Description

  The present invention relates to an edge line connecting method for connecting an edge line that electrically connects a first overhead line retained from one side to a utility pole and a second overhead line retained from the other side between the overhead lines.

  Conventionally, an overhead wire is erected on a utility pole while being tensioned by a tension clamp or the like. Then, there is an (electrically) connected edge line between the (first) overhead line that is retained from one of the utility poles and the (second) overhead line that is retained from the other so that no tension is applied. (See paragraph [0006] in Patent Document 1).

  Since no tension acts on the edge line, a power failure can be easily generated by cutting the edge line portion. Moreover, the power failure can be recovered by reconnecting the cut edge line portions (see Patent Document 2 [Background Art] and the like).

Therefore, it is possible to connect an edge line to the overhead wire so that a ground fault or a short circuit accident is unlikely to occur.
Moreover, since the coating | coated means has insulation, an edge line can be insulated by coat | covering with this coating | coated means. Therefore, the edge line covered with the covering means can ensure insulation even when approaching the overhead line or the charging unit, and can be connected to the overhead line in a state where the insulation is ensured. Therefore, when connecting the edge line between the overhead lines, the edge line can be connected to the overhead line so that a ground fault or a short-circuit accident hardly occurs.
The edge line is bordered so that the edge line passed between one (first) overhead line and the other (second) overhead line does not bend due to its own weight and come into contact with the arm metal. Even when the support is supported by the brace and the middle part of the edge line is covered by the covering means, if the covering of the middle part of the covering means is released by the intermediate part covering releasing means, Since the covering of the middle part of the line is released, the middle part of the edge line covered by the covering means can be supported by the edge line support tool.

  The edge line connection method according to the first embodiment of the present invention will be described with reference to the drawings. First, a specific example to which the edge line connection method is applied will be described with reference to FIG. The first example to which this edge line connection method is applied is an example in which the existing edge line 901 is replaced with a new edge line as shown in the side view of the periphery of the edge line in FIG. . In the second example, as shown in the side view of the periphery of the edge line in FIG. 1B, the existing edge line 901 has a connecting portion 902 between the edge lines 901. In this case, it is not easy to disconnect and reconnect. In the third example, as shown in the side external view of the periphery of the edge line in FIG. 1 (c), the end of the overhead line 904 (generally referred to as "stop") constructed on the terminal utility pole 903 is further provided. This is an example of extension. When the edge line connecting method of the present invention is applied, the edge line 901 is retained from the first overhead line 904A on which the tension is applied to the utility pole 903 and the other, as shown in FIG. 1 (d). The end of the edge line 901 is connected to the second overhead wire 904B on which the tension is applied, and further, the middle part of the edge line 901 is connected to the pin insulator 906 supported by the arm metal 905.

  In the first case and the second case, as shown in FIGS. 1 (a) and 1 (b), a portion (namely, an edge line) 901 that is held by the holding clamps 907 and 907 and is not applied with tension. When the power is cut off and then restored, as shown in FIG. 1 (d), the edge of the edge line 901 is connected from the pin insulator 906 (FIG. 1) without being connected by a crimping sleeve or the like. (Edge line shown in FIG. 1A or FIG. 1B) 901 is removed, and terminal processing is performed with terminal caps 908 and 908. Then, the insulation coating of the connecting portions of the overhead wires 904 and 904 connecting the end of the newly installed edge line 901 is peeled off, the conductive portion is exposed, and the end of the edge line 901 is connected with a crimping sleeve or the like. , 909. Further, the middle part of the newly installed edge line 901 is fixed to the pin insulator 906. In this way, the new edge line 901 is replaced.

  In addition, the first case and the second case also include a case where the edge line 901 is replaced by indirect hot line work, such as when there is no need for a power failure. That is, without cutting the existing edge line 901, the edge line 901 is newly established in parallel with the edge line 901, and then the existing edge line 901 is removed by cutting the existing edge line 901. This is an example of replacement with the edge line 901.

  It is to be noted that the edge line 901 is connected to the electric pole 903 from one side by a holding clamp 907 and the second overhead line 904B held from the other side by the holding clamp 907 without connecting the first overhead line 904A. In this case, the portion where the tension is applied by being held by the holding clamps 907 and 907 is regarded as an overhead line (first overhead line 904A or second overhead line 904B) 904, and the tension between the holding clamps 907 and 907 is increased. A portion that does not act is regarded as an edge line 901.

  Also in the third case, an edge line 901 is newly provided basically in the same manner as in the case described above. That is, the overhead wire 904 is extended by securing the extended overhead wire to the utility pole 903 via a newly established fastening clamp, and connecting the existing overhead wire 904 and the newly established overhead wire to the utility pole 903 to the edge line 901.

  Next, the edge line connection method according to the present embodiment will be described in detail with reference to FIGS. Here, the electric wire used as the edge line is in a state where the insulation coating at both ends is stripped in advance by the operator and the conductive portion is exposed. Moreover, the insulation coating is also stripped off at the connecting part on the overhead line side for connecting the edge line, and the conductive part is exposed.

  First, the edge line support tool 140 is fixed to the brace 905 (support tool fixing step S1). Specifically, the fixing portion 141a of the fixing member 141 of the edge line support tool 140 is fitted into the arm metal 905, and the movable portion 141b is moved and fixed to the arm metal 905 (see FIG. 6A).

  Next, the worker covers the electric wire (edge line) with the covering means 110 (covering step S2). Specifically, the covering means 110 is wound in the circumferential direction along the axial direction of the electric wire, and the first maintaining means 112 is closed with the longitudinal ends of the covering sheet body 111 being overlapped. The second maintaining means is formed by closing the ends of the covering sheet body 111 and flattening the covering sheet body 111 having a substantially cylindrical shape by pressing both end portions in the longitudinal direction inward. In step 113, both end portions of the covering sheet body 111 are closed. In such a state, the electric wire is insulated by the edge line insulation protector 100. This covering step S2 may be performed before the support fixture fixing step S1, or may be performed simultaneously by performing by another operator.

  Next, as shown in FIG. 6A, the edge line insulation protector 100 covered from one end to the other end of the electric wire by the covering means 110 and the electric wire (edge line) covered by the edge line insulation protector 100 are attached. And hold | maintain in the position which connects an edge line with an indirect hot wire working tool etc. (holding process S3). The indirect live-line work tool is an indirect live-line work gripper capable of gripping the edge line insulation protector 100, such as an insulated Yatco, and a tip gripping tool capable of such gripping operation is used as a tip. You may use the attached common operation stick. Moreover, if it is a case where it is directly performed by hot wire work, it may be held by an operator protected with insulating gloves or the like. In addition, since the edge line insulation protector 100 and the edge line are held while being insulated from the charging part on the pillar, it is not particularly necessary to provide insulation protection such as a protector to the charging part.

  Next, as shown in FIG. 6B, the portion of the first overhead wire 904 </ b> A on which tension is applied by being held by the utility pole 903 is connected to one end of the edge line 901 (first connection step S <b> 4). ). Specifically, the opening / closing means 131 is opened by holding the grip portion 132 of the second covering release means 130 of the edge insulation protector 100 with the indirect hot wire working tool. When the opening / closing means 131 is opened, one end of the electric wire covered with the insulating sheet 111 is opened, and the covering of the end of the covering means 110 is released. In this way, the covering is released and the end portion of the edge line 901 becomes connectable to the first overhead wire 904A. One end portion of the edge line 901 and the connection portion where the insulating coating of the first overhead wire 904A is peeled off are connected by a crimping sleeve or the like, and are insulated and protected by an insulating cover 909 or the like.

  Further, in the same manner as in the first connection step S4, the portion of the second overhead wire 904B on which the tension is applied by being retained by the utility pole 903 is connected to the other end portion of the edge line 901 (second step). Connecting step S5).

  Next, as shown in FIG. 7A, the edge line 901 insulated by the edge line insulation protector 100 is supported by the edge line support tool 140 fixed to the arm metal 905 (support step S6). Specifically, the opening / closing means 121 is opened by holding the grip portion 122 of the first covering release means 120 of the edge insulation protector 100 with the indirect hot wire working tool. When the opening / closing means 121 is opened, the middle portion of the edge line 901 covered with the insulating sheet 111 is opened, and the middle portion of the covering means 110 is released. In this way, the middle portion of the edge line 901 that has been released from the covering and can be supported is supported by the edge line support tool 140. That is, the movable piece 142b of the support member 142 of the edge line support tool 140 is opened, the middle portion of the edge line 901 is inserted inside the support member 142, and then the movable piece 142b is closed, whereby the edge line 901 is It is supported by the wire support 140.

  Note that the first connection step S4, the second connection step S5, and the support step S6 may be performed in any order as long as they are after the holding step S3.

  Finally, as shown in FIG. 7B, after connecting the edge line 901 between the overhead lines 904A and 904B, the edge line insulation protector 100 is removed from the edge line 901 (removal step S7). Specifically, the indirect live-line work tool is gripped by the grip piece 114b of the maintenance release unit 114 provided at a predetermined interval in the longitudinal direction, and the other indirect live-line work tool is gripped by the sheet end 114a. Then, when the indirect hot-wire working tool is operated so as to separate one end portion and the other end portion of the overlapping covering sheet body 111, the first maintaining means 112 and the second maintaining means 113 are separated, and the covering is performed. The covering with the sheet body 111 is released. By repeating this operation, all the covering by the covering sheet body 111 covered along the edge line 901 is released, and the edge line insulating protective device 100 is removed from the edge line 901.

  In this way, the portions of the overhead wires 904A and 904B in which tension is applied by being held by the power pole 903 (for example, when the overhead wires 904A and 904B are held between the power poles 903 by the holding clamps 907 and 907). If there is, the edge line 901 can be connected to a holding clamp 907 that holds one end of the overhead wires 904A and 904B and a holding clamp 907 that holds the other end of the overhead wire 904A, 904B. Since the edge line 901 is not connected to a position where it is easily formed (position on the electric pole 903 side with respect to the retaining clamp 907), the edge line can be connected to the overhead wire so that a ground fault or a short-circuit accident is unlikely to occur.

  Further, since the covering means 110 has an insulating property, the edge line 901 can be insulated by being covered with the covering means 110. Therefore, even if the edge line 901 covered with the covering means 110 is brought close to the overhead line 904 or the charging unit, the insulation 901 can be secured, and can be connected to the overhead line 904 with this insulation secured. Therefore, even when the edge line 901 is connected between the overhead lines 904A and 904B, the edge line can be connected to the overhead line so that a ground fault or a short-circuit accident hardly occurs.

  The edge line 901 passed between one (first) overhead line 904A and the other (second) overhead line 904B is not bent by its own weight or the like so as to come into contact with the arm metal 905 or the like. Even when the wire 901 is supported on the arm metal 905 by the edge line support tool 140 and the middle part of the edge line 901 is covered by the covering means 110, the first covering release means 120 covers the wire 901. When the covering of the middle part of the means 11 is released, the covering of the middle part of the edge line 901 is released, so that the middle part of the edge line 901 covered by the covering means 110 can be supported by the edge line support tool 140. it can.

  Further, when covering the edge line 901, by closing the opening and closing means 121, the edge line 901 is covered to ensure insulation, and when supporting the middle part of the edge line 901 on the edge line support 140, By opening the opening / closing means 121, the insulation in the middle of the edge line 901 can be released.

  For example, when the edge line 901 is connected between the overhead lines 904A and 904B in the live line state, the existing edge line 901 in the live line state is connected to the edge line support 140 such as a pin insulator that supports the edge line 901. Even when the newly installed edge line 901 cannot be supported by being supported, the newly installed edge line 901 can be supported by fixing the edge line support tool 140 according to the present invention to the arm metal 905.

  Even if the end of the edge line 901 is covered with the covering means 110, if the covering of the end of the covering means 110 is released by the second covering releasing means 130, Since the covering is released, the end of the edge line 901 covered by the covering means 110 and the overhead wire 904 can be connected.

  Further, when covering the edge line 901, the opening / closing means 131, 131 are closed to ensure insulation by covering the edge line 901, and when connecting the end of the edge line 901 to the overhead line 904, By opening the means 131, 131, the insulation at the end of the edge line 901 can be released.

  Further, even if the edge line 901 is in a state of being fitted according to the shape spanned between the overhead lines 904 and 904, the covering sheet body 111 can be covered along the edge line 901. Further, for example, after being connected to the overhead line 901 or supported by the edge line support tool 140, the covering means 110 can be removed from the edge line 901 in the circumferential direction of the edge line 901. It can be reused to connect other edge lines 901.

  In addition, after being connected to the overhead line 904 or supported by the edge line support tool 140, the edge line insulation protector 100 can be removed from the edge line 901 and used for connection to another edge line 901.

  Next, the edge line connection method according to the second embodiment will be described in detail. First, the configuration of the edge line insulation protector 200 used in the edge line connection method according to the present embodiment will be described with reference to FIG. In addition, since the edge line support tool used for the edge line connection method according to the present embodiment is the same as the edge line support tool 140 according to the first embodiment, description of the configuration is omitted. The description of the configuration similar to that of the edge line insulation protector 100 according to the first embodiment is also omitted for the edge line insulation protector 200.

  Similarly to the edge line insulation protector 100 according to the first embodiment, the edge line insulation protector 200 includes a covering means 210, a first covering release means 220, and a second covering release means 230.

  The covering means 210 includes a covering cylinder 211 that is formed in a cylindrical shape and can be covered from the circumferential direction of the edge line, and a storage means 212 that stores the edge line inside the covering cylinder 211.

  The covered cylinder 211 is a cylindrical tube having at least a length in the longitudinal direction of the electric wire to be covered and an inner diameter not less than the diameter of the electric wire to be covered. As the covering cylinder 211, one having a large electric insulation and dielectric strength is selected.

  The covering cylinder 211 has expansion / contraction portions 211a and 211a that can expand and contract in the axial direction of the edge line to be covered while the edge line can be covered. Specifically, the stretchable part 211a is a bellows (also called bellows). The expansion / contraction part 211a can be adjusted by expanding / contracting the length of the coated cylinder 211 in the cylinder core direction. Specifically, the covering cylinder 211 can be extended to the length of the edge line in the axial direction by extending the stretchable portion 211a. The covering cylinder 211 can be contracted to a length equal to or less than the length of the edge line in the axial direction by contracting the stretchable portion 211a.

  The storage means 212 includes a storage path 212a formed by continuous breakage along the longitudinal direction of the covering cylinder 211, and gripping portions 212b, 212b,... Respectively disposed on both sides of the storage path 212a. Prepare.

  The storage path 212a is formed by separating the end portions along the longitudinal direction of the coated cylindrical body 211 in the circumferential direction, and is formed so as to open to the extent that the edge line can be inserted, while storing the edge line. After that, it is formed so as to be closed (by elastic deformation). That is, as long as the coated cylindrical body 211 does not act in the direction in which the end portions along the longitudinal direction are forcibly separated, the end portions are processed so as to return to a state where they are close to or in contact with each other.

  The gripping portions 212b, 212b,... Are formed so as to protrude in a direction perpendicular to the surface of the covering cylinder 211 so as to be gripped by the indirect hot wire working tool, and a plurality of gripping portions 212b, 212b,. The gripping portions 212b, 212b,... Use a pair of gripping portions 212b, 212b provided on both sides across the storage path 212a. In other words, by operating the gripping portions 212b and 212b so as to be separated in the circumferential direction, the end portions along the longitudinal direction of the covering cylindrical body 211 are separated from each other, and the storage path 212a is set to be equal to or larger than the diameter of the edge line. The edge line can be accommodated from the radial direction of the coated cylinder 211.

  The first covering release means 220 includes a dividing means 221 that can divide the middle part of the covering cylinder 211 into a plurality of parts in the cylinder core direction, and a gripping part 222 that holds the dividing means 221 for the dividing operation. .

  The dividing means 221 is configured to be split into two in the longitudinal direction of the coated cylinder 211 and can separate the coated cylinder 211 into a first divided body 211A and a second divided body 211B. The first divided body 211A is a covered cylinder 211 on the first overhead line side, and the second divided body 211B is a covered cylinder 211 on the second overhead line side. In the first divided body 211A and the second divided body 211B, the opening end surface of the first divided body 211A is formed in a concave shape, the opening end surface of the second divided body 211B is formed in a convex shape, and each of the first divided body 211A is engaged in an uneven shape. Are combined. The dividing unit 221 divides the uneven engagement into the first divided body 211A and the second divided body 211B.

  The gripping part 222 has the same configuration as the gripping parts 212b, 212b,... Of the storage means 212, and straddles the connecting part between the first split body 211A and the second split body 211B, and the first split body 211A and the second split body. A pair of gripping portions 212b and 212b provided at respective end portions that couple to the body 211B is used as a set. Therefore, by operating the grip portion 222 to be separated in the longitudinal direction, the opening end portions of the first divided body 211A and the second divided body 211B engaged with each other are separated from each other, and the first divided body 211A is separated. And the second divided body 211B.

  The second covering releasing means 230 includes dividing means 231 and 231 that can divide the end portion of the covering cylindrical body 211 into a plurality of parts in the cylinder core direction, and a holding part 232 that holds the dividing means 231 and 231 for the dividing operation. , 232.

  The dividing means 231 and 231 are configured to be capable of being divided into two in the longitudinal direction of the coated cylindrical body 211, and the divided first divided body 211A or second divided body 211B, and the first divided body 211A or the second divided body. It separates into lids 231A and 231B that close the opening of 211B. The first lid body 231A is the first overhead wire side coated cylinder 211 (first divided body 211A), and the second lid body 231B is the second overhead line side coated cylinder 211 (second divided body). Body 211B). The first divided body 211A and the first lid body 231A are formed such that the opening end surface of the first divided body 211A is formed in a concave shape, and the opening end surface of the first lid body 231A is formed in a convex shape. Have been combined. Then, the dividing unit 231 divides the uneven engagement into the first divided body 211A and the first lid 231A. The second divided body 211B and the second lid body 231B are formed such that the opening end surface of the second divided body 211B is formed in a convex shape, and the opening end surface of the second lid body 231B is formed in a concave shape. Engaged and connected. Then, the dividing unit 231 divides the uneven engagement into the second divided body 211B and the second lid body 231B.

  The grip portion 232 has the same configuration as the grip portions 212b, 212b,... Of the storage means 212, and straddles the connecting portion between the first divided body 211A and the first lid body 231A, and the first divided body 211A and the first portion. A pair of gripping portions 212b and 212b provided at the respective end portions that join the lid body 231A is used as a set. Therefore, by operating the grip portion 232 to be separated in the longitudinal direction, the opening end portions of the first divided body 211A and the first lid body 231A engaged with the concave and convex portions are separated from each other, and the first divided body is separated. It can be divided into 211A and a first lid 231A.

  In addition, a pair of gripping portions provided at respective end portions that couple the second divided body 211B and the second lid 231B across the coupling portion between the second divided body 211B and the second lid 231B. 212b and 212b are used as a set. Therefore, by operating the grip portion 232 so as to be separated in the longitudinal direction, the opening ends of the second divided body 211B and the second lid body 231B engaged with each other are separated from each other, and the second divided body is separated. It can be divided into 211B and a second lid 231B.

  Next, the edge line connection method according to the present embodiment will be described in detail with reference to FIGS. 9 and 10. First, the edge line support tool 140 is fixed to the brace 905 (support tool fixing step S1).

  Next, the worker covers the electric wire (edge line) with the covering means 210 (covering step S2). Specifically, the gripping portions 212b and 212b of the storage means 212 are gripped by an indirect live work tool or the like, and are separated in the circumferential direction of the covering means 210 in a state where the first divided body 211A and the second divided body 211B are coupled. Thus, the storage path 212a is formed. An electric wire is accommodated inside the covered cylindrical body 211 (first divided body 211A and second divided body 211B) via the opened storage path 212a to cover the electric wire. Then, the first lid body 231A and the second lid body 232B are fitted into the open end portions of the first divided body 211A and the second divided body 211B that are left open, the openings are closed, and the both end portions of the electric wire are Cover. By setting it as such a state, an electric wire is insulated with the edge line insulation protector 200. FIG. This covering step S2 may be performed before the support fixture fixing step S1, or may be performed simultaneously by performing by another operator.

  Next, as shown in FIG. 9A, the edge line insulation protector 200 covered from one end to the other end of the electric wire by the covering means 210 and the electric wire covered by the edge line insulation protector 200 are indirectly hot-wired. The edge line 901 is held at a position where it is connected with a work tool or the like (holding step S3). In addition, since the edge line insulation protector 200 and the electric wire are held while being insulated from the charging part on the pillar, it is not particularly necessary to provide insulation protection such as a protector to the charging part.

  Next, as shown in FIG. 9B, the portion of the first overhead wire 904 </ b> A on which tension is applied by being retained by the utility pole 903 is connected to one end portion of the edge line 901 (first connection step S <b> 4). ). Specifically, the dividing unit 231 is divided by holding the holding part 232 of the second covering release unit 230 of the edge line insulation protective device 200 with the indirect hot wire working tool. The dividing means 231 is divided, and the first lid 231A is separated from the first divided body 211A. Further, by contracting the stretchable portion 211a, the end portion of the edge line 901 having a length necessary for connecting the edge line 901 to the first overhead line 904A is exposed from the first divided body 211A. One end of the edge line 901 covered with the covering cylinder 211 is opened, and the covering of the end of the covering means 210 is released. In this way, the covering is released and the end portion of the edge line 901 becomes connectable. One end portion of the edge line 901 and the connection portion where the insulating coating of the first overhead wire 904A is peeled off are connected by a crimping sleeve or the like, and are insulated and protected by an insulating cover 909 or the like.

  Further, in the same manner as in the first connection step S4, the portion of the second overhead wire 904B on which the tension is applied by being retained by the utility pole 903 is connected to the other end portion of the edge line 901 (second step). Connecting step S5).

  Next, as shown in FIG. 10A, the edge line 901 insulated by the edge line insulation protector 200 is supported by the edge line support tool 140 fixed to the arm metal 905 (support step S6). Specifically, the dividing unit 221 is divided by holding the holding part 222 of the first covering release unit 220 of the edge line insulation protective device 200 with the indirect hot wire working tool. The dividing means 221 is divided to separate the first divided body 211A and the second divided body 211B. Furthermore, the gap between the first divided body 211A and the second divided body 211B is widened by shrinking the stretchable portions 211a and 211a. The middle part of the edge line 901 covered with the covering cylinder 211 is opened, and the middle part of the covering means 210 is released. In this way, the middle portion of the edge line 901 that has been released from the covering and can be supported is supported by the edge line support tool 140. That is, the movable piece 142b of the support member 142 of the edge line support tool 140 is opened, the middle portion of the edge line is inserted inside the support member 142, and then the movable piece 142b is closed to support the edge line. It is supported by the tool 140.

  Note that the first connection step S4, the second connection step S5, and the support step S6 may be performed in any order as long as they are after the holding step S3.

  Finally, as shown in FIG. 10B, after connecting the edge line 901 between the overhead lines 904A and 904B, the edge line insulation protector 200 is removed from the edge line 901 (removal step S7). Specifically, the indirect live-line work tool is gripped by the grip portion 212b of the storage means 212 provided along one longitudinal end of the cover cylinder 211, and the other indirect live-line work tool is covered with the cover cylinder. The grip part 212b of the storage means 212 provided along the other end of 211 is gripped. When the indirect hot wire working tool is operated so as to separate the circumferential direction of the covering cylinder 211, the storage path 212 a is opened, and the edge line insulation protector 200 is removed through the storage path 212 a through the edge line 901.

  In this way, the portions of the overhead wires 904A and 904B in which tension is applied by being held by the electric pole 903 (for example, when the overhead wires 904A and 904B are held between the electric poles 903 by the holding clamps 90 and 907) If there is, the edge line 901 can be connected to a holding clamp 907 that holds one end of the overhead wires 904A and 904B and a holding clamp 907 that holds the other end of the overhead wire 904A, 904B. Since the edge line 901 is not connected to a position where it is easily formed (position on the electric pole 903 side with respect to the retaining clamp 907), the edge line can be connected to the overhead wire so that a ground fault or a short-circuit accident is unlikely to occur.

  Moreover, since the coating | coated means 210 has insulation, the edge line 901 can be insulated when this coating | coated means 210 is coat | covered. Therefore, even if the edge line 901 covered with the covering means 210 is brought close to the overhead line 904 or the charging unit, the insulation 901 is ensured, and can be connected to the overhead line 904 in a state where this insulation is ensured. Therefore, even when the edge line 901 is connected between the overhead lines 904A and 904B, the edge line can be connected to the overhead line so that a ground fault or a short-circuit accident hardly occurs.

  The edge line 901 passed between one (first) overhead line 904A and the other (second) overhead line 904B is not bent by its own weight or the like so as to come into contact with the arm metal 905 or the like. Even when the wire 901 is supported on the arm metal 905 by the edge line support tool 140 and the middle part of the edge line 901 is covered by the covering means 210, the first covering release means 220 covers the wire 901. When the covering of the middle part of the means 211 is released, the covering of the middle part of the edge line 901 is released, so that the edge line support tool 140 can be supported in the middle part of the edge line 901 covered by the covering means 210. it can.

  Further, when the middle part of the edge line 901 is supported by the edge line support tool 140, the insulation of the middle part of the edge line 901 can be released by dividing the dividing means 221.

  Further, for example, in the case where the edge line 901 is connected between the overhead lines 904A and 904B in the live line state, the existing edge line in the live line state in the edge line support tool 140 such as a pin insulator that supports the edge line 901. Even when the newly installed edge line 901 cannot be supported by supporting 901, it is possible to support the newly installed edge line 901 by fixing the edge line support tool 140 according to the present invention to the arm metal 905. it can.

  Even when the end of the edge line 901 is covered with the covering means 210, when the covering of the end of the covering means 210 is released with the second covering releasing means 230, the end of the edge line 901 is removed. Since the covering is released, the end portion of the edge line 901 covered by the covering means 210 and the overhead wire 904 can be connected.

  In addition, when connecting the end portion of the edge line 901 to the overhead wire 904, the end portion of the edge line 901 can be released by separating the end portion from the covering means 210 by the dividing means 231 and 231.

  When covering the edge line 901, the covering means 211 is extended to cover the end of the edge line 901, thereby covering the edge line 901 to ensure insulation and connecting the end of the edge line 901 to the overhead wire 904. In this case, the insulation of the end portion of the edge line 901 can be released by shrinking the covering means 211 to expose the end portion of the edge line 901.

  Further, even if the edge line 901 is in a state of being creased according to the shape spanned between the overhead lines 904, the covered cylindrical body 211 can be covered along the edge line 901. Further, for example, after being connected to the overhead wire 901 or supported by the edge line support tool 140, the covering means 210 can be removed from the edge line 901 in the circumferential direction of the edge line 901. It can be reused to connect other edge lines 901.

  In addition, after being connected to the overhead line 904 or supported by the edge line support tool 140, the edge line insulation protector 200 can be removed from the edge line 901 and used for connection to another edge line 901.

  Next, the edge line connection method according to the third embodiment will be described in detail. First, the configuration of the edge line insulation protector 300 used in the edge line connection method according to the present embodiment will be described with reference to FIGS. 11 and 12. In addition, since the edge line support tool used for the edge line connection method according to the present embodiment is the same as the edge line support tool 140 according to the first embodiment, description of the configuration is omitted. Also, with regard to the edge line insulation protector 300, the description of the same configuration as the edge line insulation protector 100 according to the first embodiment and the edge line insulation protector 200 according to the second embodiment will be omitted.
