Description
本発明は、複数連の耐張碍子装置における避雷装置取付構造に関するものである。 The present invention relates to a lightning arrester mounting structure in a plurality of continuous tension insulators.
従来から、送電線等への落雷から耐張碍子連を保護することを目的として、耐張碍子連の両端にアークホーンが設置されている。さらに近年では、酸化亜鉛素子を内蔵する避雷装置を耐張碍子連に取付け、雷サージ電流を鉄塔に流すことにより耐張碍子連の損傷を抑制する技術が知られている。 Conventionally, arc horns have been installed at both ends of a tension insulator series for the purpose of protecting the tension insulator series from lightning strikes on a transmission line or the like. Further, in recent years, a technique is known in which a lightning arrester incorporating a zinc oxide element is attached to a tension insulator series and a lightning surge current is passed through a steel tower to suppress damage to the tension insulator series.
酸化亜鉛素子は非直線な電流―電圧特性を持っているため、電力系統の運転電圧に対しては絶縁体として機能するが、系統に雷サージによる高電圧が発生した場合は、導体として機能して高電圧を接地側に逃がすとともに、続流を遮断することができる特徴を持つ。 Since zinc oxide elements have non-linear current-voltage characteristics, they function as insulators for the operating voltage of the power system, but they function as conductors when high voltage is generated by lightning surges in the system. The high voltage can be released to the ground side and the continuity can be cut off.
このような避雷装置を２連耐張碍子装置に取付けた例が、特許文献１に記載されている。特許文献１に示されているように、接地側と課電側にそれぞれヨークを備えた２連耐張碍子装置においては、ヨークの中央に避雷装置や電極を設置することができる。しかし、荷重の1点集中箇所を避けようとしたり、碍子連破断時に残存碍子連の損傷を防止する配慮をする場合等には、ヨークを備えない２連耐張碍子装置を形成することがあり、そのような場合に片側の碍子連に避雷装置や電極を設置すると重量バランスが崩れ、２連耐張碍子装置がねじれてしまうことがあった。また、前記ねじれにより金具に特殊な荷重が加わることになり、強度や耐久性を損なうので好ましくない。 An example in which such a lightning arrester is attached to a dual tension insulator device is described in Patent Document 1. As shown in Patent Document 1, in a two-strand tension insulator device provided with yokes on the grounding side and the charging side, a lightning arrester and an electrode can be installed at the center of the yoke. However, when trying to avoid a point where the load is concentrated at one point, or when taking care to prevent damage to the remaining insulators when the insulators are broken, a double tension insulator device without a yoke may be formed. In such a case, if a lightning arrester or an electrode is installed on one side of the insulator, the weight balance may be lost, and the double tension insulator may be twisted. In addition, a special load is applied to the metal fitting due to the twist, and the strength and durability are impaired.
また避雷装置を３連耐張碍子装置に取付けた例が、特許文献２に記載されている。この場合にも避雷装置を３連耐張碍子装置の中心線上に配置して重量バランスを取っている。しかし３連耐張碍子装置は２連ヨークを重ねた特殊な３連ヨークを使用しているため、避雷装置を３連耐張碍子装置の中心線上に配置するためには特殊な取付金具やバランスウエイトを必要としており、コスト高となったり、碍子装置の重量がバランスウエイト分だけ増加してしまうという問題があった。 An example in which a lightning arrester is attached to a triple tension insulator device is described in Patent Document 2. Also in this case, the lightning arrester is arranged on the center line of the triple tension insulator device to balance the weight. However, the triple tension insulator device uses a special triple yoke with two yokes stacked. Therefore, in order to place the lightning arrester on the center line of the triple tension insulator device, a special mounting bracket or balance There is a problem that a weight is required, resulting in an increase in cost and an increase in the weight of the lever device by the balance weight.
また、特許文献１，２の何れにおいても、避雷装置を耐張碍子連の接地側に配置し、課電側に電極を配置しているが、避雷装置自体の質量によっては、その荷重による接地側金具の強度および耐久性の低下が問題となることがある。 In both Patent Documents 1 and 2, the lightning arrester is arranged on the grounding side of the tension insulator series, and the electrode is arranged on the power application side. Decrease in strength and durability of the side metal fitting may be a problem.
本発明の目的は前記した従来の問題点を解決し、碍子装置の重量増加や金具の強度および耐久性の低下を抑制しつつ、複数連の耐張碍子装置に避雷装置をねじれを生じさせることなく取付けることができる耐張碍子装置における避雷装置取付構造を提供することである。 An object of the present invention is to solve the above-described conventional problems, and to twist a lightning arrester in a plurality of tension-proof insulator devices while suppressing an increase in weight of the insulator device and a decrease in strength and durability of metal fittings. It is an object of the present invention to provide a lightning arrester mounting structure in a tension insulator that can be mounted without any problem.
上記の課題を解決するためになされた本発明は、複数連の耐張碍子連への避雷装置取付構造であって、外被内部に複数の酸化亜鉛素子を直列に備えた棒状の避雷装置を接地側と課電側とに分割し、分割された避雷装置をそれぞれ異なる耐張碍子連にバランスさせて取付けた構造を有し、接地側の避雷装置の接地側の端部は一つの耐張碍子連の接地側に取付けられ、接地側の避雷装置の他端には放電電極が設けられ、課電側の避雷装置の課電側の端部は別の耐張碍子連の課電側に取付けられ、課電側の避雷装置の他端には放電電極が設けられ、この構成によって碍子連と並列に雷サージ電流経路を形成したことを特徴とするものである。 The present invention made to solve the above problems is a lightning arrester mounting structure to a plurality of tension insulators, a rod-shaped lightning arrester comprising a plurality of zinc oxide elements in series in the outer jacket. divided into a ground and voltage application side, then the balance divided lightning arrester device to the different tension insulator strings each have a mounting structure, the end portion of the ground side of the lightning arrester device of the ground-side one tension It is attached to the ground side of the insulator series, and the discharge electrode is provided at the other end of the lightning arrester on the ground side. A discharge electrode is provided on the other end of the lightning arrester on the charging side, and a lightning surge current path is formed in parallel with the insulator series by this configuration .
なお請求項２のように、前記避雷装置は、接地側と課電側とが略同一の質量となるように分割されたものであることが好ましい。 As in claim 2, the lightning protection device is preferably divided so that the grounding side and the power application side have substantially the same mass.
本発明によれば、複数の耐張碍子連を有する耐張碍子装置において、外被内部に複数の酸化亜鉛素子を直列に備えた棒状の避雷装置を接地側と課電側とに分割し、分割された避雷装置をそれぞれ異なる耐張碍子連にバランスさせて取付けたので、耐張碍子装置のねじれを抑制することができる。このため、ヨークが存在しない２連耐張碍子装置への取付けも可能である。また３連耐張碍子装置においても、避雷装置を耐張碍子装置の中心軸上に設置する必要がなくなり、特殊な避雷装置の取付金具およびバランスウエイト等を取付ける必要がない。 According to the present invention, in a tension insulator apparatus having a plurality of tension insulator series, a rod-shaped lightning arrester provided with a plurality of zinc oxide elements in series inside the outer jacket is divided into a ground side and a power application side, since it mounted by balanced divided lightning arrester device to withstand Zhang insulator string that different respectively, it is possible to suppress the twisting of the strain insulator device. For this reason, it is possible to attach to a two-stretch tension insulator apparatus in which no yoke is present. Also in the triple tension insulator device, it is not necessary to install the lightning arrester on the central axis of the tension insulator device, and there is no need to attach a special lightning arrester mounting bracket or balance weight.
さらに、避雷装置を接地側と課電側とに分割したことにより、従来の耐張碍子連保護機能を損なうことなく、避雷装置１本当たりの質量を従来と比較して略半分とすることができる。これにより取付金具への荷重ストレスが軽減され、取付金具の損傷リスクを軽減させることができる。また、避雷装置の表面積も略半分となることから、積雪や突風等による影響を軽減させることができ、同様に取付金具の損傷リスク低下につながる。さらに、避雷装置１本当たりの質量が略半分となったことにより、運搬負荷が軽減され、従来輸送が困難であった山岳部等への避雷装置の輸送が可能となる。 Furthermore, by dividing the lightning arrester into a grounding side and a charging side, the mass per lightning arrester can be reduced to about half compared to the conventional one without deteriorating the conventional tension-proof insulator protection function. it can. As a result, load stress on the mounting bracket is reduced, and the risk of damage to the mounting bracket can be reduced. In addition, since the surface area of the lightning arrester is substantially halved, the influence of snow accumulation, gusts, etc. can be reduced, and the risk of damage to the mounting bracket is similarly reduced. Furthermore, since the mass per lightning arrester is substantially halved, the transportation load is reduced, and the lightning arrester can be transported to a mountainous area or the like that has been difficult to transport.
以下に本発明の好ましい実施形態を示す。この実施形態は接地側のヨークを持たない２連耐張碍子装置への避雷装置の取付構造を示すものである。図１および図２に示すように、各耐張碍子連２の接地側の端部は固定金具３ａによって鉄塔のアームに接続されており、課電側の端部はヨーク３ｂの両端部にそれぞれ接続されている。ヨーク３ｂの両端部の先端には、図示しない固定金具を介して送電線が取付けられている。 Preferred embodiments of the present invention are shown below. This embodiment shows a structure for mounting a lightning arrester to a two-strand tension insulator device that does not have a grounding side yoke. As shown in FIG. 1 and FIG. 2, the end on the ground side of each tension insulator 2 is connected to the arm of the steel tower by a fixing bracket 3a, and the end on the charging side is connected to both ends of the yoke 3b. It is connected. A power transmission line is attached to the tip of both ends of the yoke 3b via a fixing bracket (not shown).
各耐張碍子連２の接地側と課電側の端部には、従来と同様、アークホーン４ａと４ｂがそれぞれ設けられている。図示のように避雷装置６は接地側と課電側とに２分割され、異なる耐張碍子連２に取付けられている。接地側の避雷装置６ａは、図１における下側の耐張碍子連２に取付けられ、課電側の避雷装置６ｂは、図１における上側の耐張碍子連２に取付けられている。 The arc horns 4a and 4b are respectively provided at the end portions of the tension insulators 2 on the grounding side and the power application side, as in the conventional case. As shown in the figure, the lightning arrester 6 is divided into two parts, that is, a grounding side and a power application side, and is attached to different tension insulators 2. The grounding side lightning arrester 6a is attached to the lower tension insulator series 2 in FIG. 1, and the charging side lightning arrester 6b is attached to the upper tension insulator series 2 in FIG.
接地側の避雷装置６ａは、避雷装置本体７ａと、アダプタ８と、アダプタ８の先端に調節自在に取付けられた放電電極９ａとからなり、図２に示すように、接地側の端部は一つの耐張碍子連２の接地側の固定金具３ａに接続された取付金具５ａの先端に取付けられ、その他端には放電電極９ａが設けられている。また課電側の避雷装置６ｂは、避雷装置本体７ｂと、放電電極９ｂとから構成され、課電側の端部は別の耐張碍子連２の課電側の取付金具５ｂの先端に取付けられ、その他端には放電電極９ｂが設けられている。 The lightning arrester 6a on the ground side includes a lightning arrester main body 7a, an adapter 8, and a discharge electrode 9a that is attached to the tip of the adapter 8 so as to be adjustable . As shown in FIG. The two tension insulators 2 are attached to the tip of a mounting bracket 5a connected to the grounding-side fixing bracket 3a, and a discharge electrode 9a is provided at the other end . The lightning arrester 6b is composed of a lightning arrester main body 7b and a discharge electrode 9b, and the end of the powering side is attached to the tip of the mounting bracket 5b on the powering side of another tension-resistant insulator series 2. The other end is provided with a discharge electrode 9b .
避雷装置本体７ａ、７ｂは何れも外被の内部に多数の酸化亜鉛素子を直列に配置したものである。前記したとおり、酸化亜鉛素子は非直線な電流―電圧特性を持っているため、電力系統の運転電圧下においては絶縁体して機能するが、系統に雷サージ等の高電圧が発生した場合は、導体として機能するものである。 Each of the lightning arrester main bodies 7a and 7b has a large number of zinc oxide elements arranged in series inside the jacket. As described above, since the zinc oxide element has a non-linear current-voltage characteristic, it functions as an insulator under the operating voltage of the power system, but when a high voltage such as a lightning surge occurs in the system. It functions as a conductor.
放電電極９ａ、９ｂ間には気中ギャップ１０が形成されている。送電線に落雷した場合には、課電側の避雷装置６ｂ、気中ギャップ１０、接地側の避雷装置６ａの順に、碍子連と並列に雷サージ電流経路が形成され、耐張碍子連２を保護することができる。 An air gap 10 is formed between the discharge electrodes 9a and 9b. When lightning strikes the transmission line, a lightning surge current path is formed in parallel with the insulator series in the order of the lightning arrester 6b on the charging side, the air gap 10 and the lightning arrester 6a on the ground side. Can be protected.
本実施形態においては、図１に示すように避雷装置６ａ、６ｂを接地側と課電側とに分割し、異なる耐張碍子連２にバランスさせて配置することにより、ねじれの影響を軽減している。本実施形態においては、避雷装置６ａ、６ｂは同等の質量となるように等分されているが、厳密に２等分する必要はなく、取付金具や放電電極９ａ、９ｂの質量等を考慮して配分しても差し支えない。 In the present embodiment, as shown in FIG. 1, the lightning arresters 6a and 6b are divided into a ground side and a power application side, and are arranged in a balanced manner with different tension insulators 2 to reduce the influence of torsion. ing. In the present embodiment, the lightning arresters 6a and 6b are equally divided so as to have the same mass, but it is not necessary to strictly divide them into two, considering the mass of the mounting bracket and the discharge electrodes 9a and 9b, etc. Can be distributed.
本発明の効果を検証するため、φ２５０クレビス（直径２５０ｍｍのクレビス型懸垂碍子）×２０ヶ×２連耐張碍子装置において、図１、図２に示したように避雷装置６ａ、６ｂを接地側と課電側とに分割し、異なる耐張碍子連２にバランスさせて配置した場合（異耐張碍子連）と、図３、図４に示すように避雷装置６ａ、６ｂを接地側と課電側とに分割し、１つの耐張碍子連２にどちらも配置した場合（同耐張碍子連）とで、接地側、および課電側の装置傾き角度を傾斜角度計により計測した。図３、および図４は避雷装置６ａ、６ｂの配置が違う点を除き、その他装置の仕様、形状、および機能等は図１、および図２の耐張碍子装置１と同じものとした。電線張力は実際の取付条件を模擬し、それぞれ７００キログラム（６８６０Ｎ）、および１５００キログラム（１４７００Ｎ）の２パターンとし、また電線の振動条件は、縦方向に１００回の振動、および横方向に１００回の振動の２パターンをもって比較検討した。測定は振動の直後に行った。なお、縦方向および横方向の振動は人力によるものとする。前記パターンにおけるそれぞれの避雷装置６ａ、６ｂの傾き角度を表１に示した。 In order to verify the effect of the present invention, in a φ250 clevis (clevis-type suspension insulator with a diameter of 250 mm) × 20 pieces × two continuous tension insulator devices, as shown in FIGS. 1 and 2, the lightning arresters 6a and 6b are connected to the ground side. 3 and 4 and divided into a different tension-resistant insulator series 2 (different tension-resistant insulator series), and as shown in FIGS. 3 and 4, the lightning arresters 6a and 6b are connected to the ground side and In the case where it was divided into the electric side and both were arranged in one tension insulator series 2 (same tension insulator series), the inclination angle of the device on the ground side and the charging side was measured by an inclination angle meter. 3 and 4 are the same as those of the tension insulator device 1 shown in FIGS. 1 and 2 except for the difference in the arrangement of the lightning arresters 6a and 6b. The wire tension simulates the actual installation conditions, and each pattern has two patterns of 700 kg (6860 N) and 1500 kg (14700 N). The vibration conditions of the wires are 100 vibrations in the vertical direction and 100 times in the horizontal direction. A comparison was made with two vibration patterns. The measurement was performed immediately after vibration. Note that vibration in the vertical and horizontal directions is caused by human power. Table 1 shows the inclination angles of the lightning arresters 6a and 6b in the pattern.
表１に示すように、縦方向に１００回および横方向に１００回振動を加えた際の数値を比較すると、避雷装置６ａ、６ｂを接地側と課電側とに分割し、異なる耐張碍子連２にバランスさせて配置することにより、同耐張碍子連２に避雷装置６ａ、６ｂを配置する場合と比較して、課電側の傾き角度が小さくなることが確認され、結果ねじれの影響を軽減することができることが示された。 As shown in Table 1, when comparing the numerical values when vibration is applied 100 times in the vertical direction and 100 times in the horizontal direction, the lightning arresters 6a and 6b are divided into the ground side and the charging side, and different tension insulators Compared to the case where the lightning arresters 6a and 6b are arranged in the tension insulator series 2, it is confirmed that the inclination angle on the charging side becomes smaller by arranging the balance in the series 2 and the influence of twisting as a result. It was shown that can be reduced.
このように本発明によれば、避雷装置を接地側と課電側とに分割し、異なる該耐張碍子連にバランスさせて取付けることにより、本実施形態のように既設の２連耐張碍子装置１にヨークが存在しない場合にも、耐張碍子連２に避雷装置６ａ、６ｂを取付けることが可能となる。また、３連耐張碍子装置においても、避雷装置６ａ、６ｂを耐張碍子装置の中心軸上に設置する必要がなくなり、特殊な避雷装置の取付金具およびバランスウエイト等をなくすことが可能となる。 As described above, according to the present invention, the lightning arrester is divided into the ground side and the power application side, and is mounted in a balanced manner to the different tension insulators. Even when the device 1 does not have a yoke, the lightning arresters 6a and 6b can be attached to the tension insulators 2. Also in the triple tension insulator device, it is not necessary to install the lightning arresters 6a and 6b on the central axis of the tension insulator device, and it is possible to eliminate special lightning arrester mounting brackets and balance weights. .
また本発明によれば、接地側および課電側に設置した避雷装置６ａ、６ｂの質量を略同一とし、各質量は従来の避雷装置の略半分とすることができる。このように各避雷装置の質量を略半分として耐張碍子装置１の両端に設置することにより、取付金具５ａ、５ｂへの荷重ストレスが軽減される。これにより取付金具５ａ、５ｂの損傷リスクを軽減させることができる。また、避雷装置６ａ、６ｂの表面積も略半分となることから、積雪や突風等による影響を軽減させることができ、同様に取付金具５ａ、５ｂの損傷リスク低下につながる。さらに、避雷装置６ａ、６ｂ１本当たりの質量が略半分となったことにより、運搬負荷が軽減され、従来輸送が困難であった山岳部等への避雷装置の輸送が可能となる。 Moreover, according to this invention, the mass of the lightning arresters 6a and 6b installed on the ground side and the charging side can be made substantially the same, and each mass can be made almost half that of the conventional lightning arrester. In this way, by installing the lightning arresters at both ends of the tension insulator 1 with the mass of each lightning arrester approximately halved, load stress on the mounting brackets 5a and 5b is reduced. Thereby, the damage risk of the mounting brackets 5a and 5b can be reduced. Moreover, since the surface area of the lightning arresters 6a and 6b is also substantially halved, it is possible to reduce the effects of snow accumulation, gusts, and the like, and similarly to the risk of damage to the mounting brackets 5a and 5b. Furthermore, since the mass per lightning arrester 6a, 6b is substantially halved, the transportation load is reduced, and the lightning arrester can be transported to a mountainous area or the like, which has been difficult to transport conventionally.
