Description

本発明は、仮設用継電装置に関する。 The present invention relates to a temporary relay device.

従来、建築物の建設中には、仮設配電盤を設け、仮設配電盤に商用電源からの電力を引き込み、建築物の各階へと作業のために使用する電力を提供している。従来の仮設配電盤は、商用電源からの電力を引き込むため、特定の階層における作業が終了した後、商用電源の接続された仮設配電盤からの電力を別の階に延長し、作業者による他の階層での作業が行われる。 Conventionally, during the construction of a building, a temporary switchboard is provided, and electric power from a commercial power source is drawn into the temporary switchboard to provide electric power used for work to each floor of the building. Since the conventional temporary switchboard draws power from the commercial power supply, after the work in a specific layer is completed, the power from the temporary switchboard to which the commercial power supply is connected is extended to another floor, and the power from the temporary switchboard connected to the commercial power supply is extended to another floor. Work is done in.

各階層での作業は、並行的に行われることもあり、また、現住建造物の作業では、商用電源からの電力供給を継続したまま、電源ケーブルを延長することが要求される場合も多い。このため、このような作業は、電気工事士資格を有する作業者が、十分注意を払い行うことになるが、それでも雨中、暗中、狭隘部での作業を行う場合、感電する可能性が排除できず、熟練者と雖も特に注意を必要とする作業となっている。 The work at each level may be performed in parallel, and the work of the existing building often requires the extension of the power cable while continuing the power supply from the commercial power source. For this reason, such work must be performed by a qualified electrician with sufficient caution, but the possibility of electric shock can be eliminated when working in the rain, in the dark, or in a narrow area. However, it is a work that requires special attention even for skilled workers and 雖.

これまで、仮設電源の設置に関して、検討されており、例えば、特開２００２−６１４２０号公報（特許文献１）では、建築現場の狭隘で煩雑なスペースに、上下に分割された仮設電柱を一人の作業者で短時間のうちに、容易に、安全に立設でき、また、使用済みの仮設電柱を容易に撒去回収できる装置を提供する技術が提案されている。 So far, the installation of a temporary power supply has been studied. For example, in Japanese Patent Application Laid-Open No. 2002-61420 (Patent Document 1), one person has a temporary utility pole divided into upper and lower parts in a narrow and complicated space at a construction site. A technique has been proposed for providing a device that allows an operator to easily and safely stand up in a short time and to easily remove and collect used temporary utility poles.

特許文献１の技術は知られているものの、仮設配電盤を他の階層に延長する際に安全、かつ効率的に施工する技術が現在でも必要とされていた。 Although the technique of Patent Document 1 is known, a technique for safely and efficiently constructing a temporary switchboard when extending it to another layer is still required.

以下、本発明を実施形態により説明するが、本発明は、後述する実施形態に限定されるものではない。図１は、本実施形態の仮設継電装置１１２が配設された施工現場１００の実施形態を示す。施工中の建造物１１０には、施工のための足場１１１が仮設されており、足場を介して、作業者が、建造物１１０の外部を施工し、また、建造物１１０の内部を施工することが可能とされている。 Hereinafter, the present invention will be described with reference to embodiments, but the present invention is not limited to the embodiments described later. FIG. 1 shows an embodiment of a construction site 100 in which the temporary relay device 112 of the present embodiment is arranged. A scaffolding 111 for construction is temporarily installed in the building 110 under construction, and the worker constructs the outside of the building 110 and the inside of the building 110 through the scaffolding. Is possible.

建造物１１０の外部や内部を施工するためには、少なからず電力を使用する装置が利用されるため、通常では、建造物１１０から離れた箇所に仮設用電柱１２０を設け、送電線１３０から仮設電線１２１を引き込み、電気メーター１２２および引込開閉器１２３および電線１２４を経由した仮設電力を使用して仮設用継電装置１１２から、建造物１１０の内部に電力を供給する。 Since a device that uses electric power is used to construct the outside and the inside of the building 110, a temporary electric pole 120 is usually provided at a place away from the building 110 and temporarily installed from the transmission line 130. The electric wire 121 is pulled in, and electric power is supplied from the temporary relay device 112 to the inside of the building 110 by using the temporary electric power via the electric meter 122, the retractable switch 123, and the electric wire 124.

仮設用継電装置１１２からは、各階層の施工を行うための機器が要求する電圧、相の電力が図示しない電線を介して建造物１１０内に引き込まれ、各種の作業を可能としている。 From the temporary power relay device 112, the voltage and phase power required by the equipment for performing the construction of each layer are drawn into the building 110 via electric wires (not shown), enabling various operations.

例えば図１に示した実施形態において、１階での作業を終了した場合や、複数の階層での作業を並列的に行う必要が生じた場合、２階に仮設用配電盤を設置し、電線１２４を２階の仮設用配電盤１１２に接続することで２階における施工のための電源を確保する。このような切り替え作業は、他の施工を完全に中止して行う場合を除き商用電源からの電力供給を受けた状態で電線接続を行わなければならない状況となる。また、その他、現住の建造物１１０を施工する場合、居住用の電力を停止できないため、同様に商用電源からの電力が供された状態での電線延長工事が行われる。 For example, in the embodiment shown in FIG. 1, when the work on the first floor is completed or when it becomes necessary to perform the work on a plurality of layers in parallel, a temporary switchboard is installed on the second floor and the electric wire 124 is installed. Is connected to the temporary switchboard 112 on the second floor to secure a power source for construction on the second floor. Such switching work is a situation in which the electric wires must be connected while receiving power from a commercial power source, unless other construction is completely stopped. In addition, when constructing the existing building 110, since the electric power for residential use cannot be stopped, the electric wire extension work is also carried out in the same state where the electric power from the commercial power source is supplied.

従来、作業者が、直接生きた電気の来ている電線を加工し、接続を行う。作業者は、電気工事士の資格を有しているとは言え、生きた電力が供給された電線を施工するのは、十分な注意が必要とされる。また、近年の少子高齢化の影響により施工者が高齢化すること、また外国人労働者の増加が予測されることから、さらに安全性を向上し、効率化することが喫緊の課題である。 Conventionally, a worker processes and connects an electric wire directly receiving live electricity. Although workers are qualified as electricians, they need to be very careful when constructing live-powered wires. In addition, as the number of contractors is aging due to the recent declining birthrate and aging population, and the number of foreign workers is expected to increase, it is an urgent issue to further improve safety and efficiency.

そこで、本実施形態では、仮設用継電装置１１２を、電気自動車の充電や電気自動車から電力を引き出すためのＥＶ用プラグを使用して構成する。また、工事用電線の延長は、ＥＶ用プラグを両端に接続した延長ケーブルに１１３を使用して行う。このため、例えば２階での作業が必要となった場合、１階の仮設用継電装置１１２の出力側のＥＶ用プラグに適合するＥＶ用プラグを備えた延長ケーブル１１３を接続し、延長ケーブル１１３の他端を、２階に設置された仮設用継電装置１１２の入力側のＥＶ用プラグに接続する。 Therefore, in the present embodiment, the temporary relay device 112 is configured by using an EV plug for charging an electric vehicle or drawing power from the electric vehicle. Further, the extension of the construction electric wire is performed by using 113 for the extension cable in which the EV plug is connected to both ends. Therefore, for example, when work on the second floor is required, an extension cable 113 having an EV plug compatible with the EV plug on the output side of the temporary relay device 112 on the first floor is connected, and the extension cable is connected. The other end of 113 is connected to the EV plug on the input side of the temporary power relay device 112 installed on the second floor.

このため、作業者は、生きた電線を直接施工することなく、ＥＶ用プラグを介して工事用電力を延長することができ、また延長ごとに生きた電力の通じた電線を施工することが無くなる。さらに、同時的に３階、４階の施工が必要となった場合にでも、適宜仮設用継電装置１１２を増設することで、同時並列的に複数階の階層へと、一本の電線１２４からの電力供給で、ＥＶ用プラグの電力制限の上限まで電力を供給することが可能となり、施工効率が改善される。 For this reason, the worker can extend the construction power through the EV plug without directly constructing the live electric wire, and also eliminates the need to construct the live electric wire for each extension. .. Further, even if the construction of the 3rd floor and the 4th floor is required at the same time, by adding the temporary power relay device 112 as appropriate, one electric wire 124 can be simultaneously connected to the multiple floors in parallel. By supplying power from, it becomes possible to supply power up to the upper limit of the power limit of the EV plug, and the construction efficiency is improved.

図２は、本実施形態の仮設用継電器１１２の機能構成を示した図である。図２に示すように仮設用継電装置１１２は、従来の配電盤と類似の構造を有しているが、電力の入力用のＥＶ用プラグ２０１と、電力の出力用のＥＶ用プラグ２０４とが筐体に備えられている。ＥＶ用プラグ２０１は、メスコネクタとして実装され、ＥＶ用プラグ２０４はオスコネクタとして実装することができる。 FIG. 2 is a diagram showing a functional configuration of the temporary relay 112 of the present embodiment. As shown in FIG. 2, the temporary power relay device 112 has a structure similar to that of a conventional switchboard, but has an EV plug 201 for power input and an EV plug 204 for power output. It is provided in the housing. The EV plug 201 can be mounted as a female connector, and the EV plug 204 can be mounted as a male connector.

また、ＥＶ用プラグ２０１には、対応するオスのＥＶ用プラグ２０３が挿入されて電力の供給を行い、ＥＶ用プラグ２０４には、対応するメスのＥＶ用プラグ２０２が装着されて、電力の出力が行われる。ＥＶ用プラグとしては、これまで知られたいかなる形式のものでもよく、例えば日本配線システム工業規格ＪＷＤＳ−００３３、国際規格ＩＥＣ：６１８５１−１ ｅｄ．２．０ ＡｎｎｅｘＡで規定される規格に適合するものを使用することができまた、チャデモ、コンボ方式のいずれに適合する形式のプラグでもよい。 Further, the corresponding male EV plug 203 is inserted into the EV plug 201 to supply electric power, and the corresponding female EV plug 202 is attached to the EV plug 204 to output electric power. Is done. The EV plug may be of any type known so far, for example, Japan Wiring System Industrial Standard JWDS-0033, International Standard IEC: 61851-1 ed. A plug that conforms to the standard specified by 2.0 Annex A can be used, and a plug that conforms to either the CHAdeMO or combo method may be used.

ＥＶ用プラグ２０１と、ＥＶ用プラグ２０４との間には、ブレーカー２０３が配置されていて過電流を保護することができる構成とされている。また、図示した実施形態では、ブレーカー２０３の下流側から電力切替装置２０５を介して各階負荷２０６へと電力が供給されている。電力切替装置２０５は、供給された電力を各階負荷２０６が利用できる形式の電圧および相に変換する機能を有する。例えば、引込開閉器から供給されるのが、２００Ｖ３相交流の場合、１００Ｖ２相交流に変換する処理を行うことができる。 A breaker 203 is arranged between the EV plug 201 and the EV plug 204 so that an overcurrent can be protected. Further, in the illustrated embodiment, electric power is supplied from the downstream side of the breaker 203 to each floor load 206 via the electric power switching device 205. The power switching device 205 has a function of converting the supplied power into a voltage and phase of a form that can be used by each floor load 206. For example, in the case of 200V 3-phase AC supplied from the retractable switch, it is possible to perform a process of converting to 100V 2-phase AC.

また、引込開閉器２０３から供給されるのが、例えば、ＥＶ用の充電スタンドからの交流電力または仮設電力としてＥＶの二次電池からの直流電流を使用する場合、または仮設電力として家屋に配設されたＥＶ充電用プラグからの電力を使用する場合、電力切替装置２０５は、各階負荷２０６が利用できる形式の電力形式に変換する機能を備えていても良い。例えば、このために使用する電力切替装置２０５は、特開２０１８−１０７８７９号公報に記載された電力切替装置を使用することができる。 Further, what is supplied from the retractable switch 203 is, for example, when AC power from a charging stand for EV or DC current from an EV secondary battery is used as temporary power, or is arranged in a house as temporary power. When using the power from the EV charging plug, the power switching device 205 may have a function of converting the power format into a format that can be used by the load 206 on each floor. For example, as the power switching device 205 used for this purpose, the power switching device described in Japanese Patent Application Laid-Open No. 2018-107879 can be used.

また、ＥＶ用プラグ２０４には、特に制限はないが、引込み開閉器や、ＥＶ充電スタンド、ＥＶの二次電池からの直流電力をそのまま、他の階層の仮設用継電装置１１２へと送付する構成とされている。このため、各仮設用継電装置１１２は、同一の構成とすることができ、特定の実施態様の必要に応じて、個別に設置することができるし、また適宜、仮設用継電装置１１２を移設して電力供給を行うことができる。 Further, the EV plug 204 is not particularly limited, but the DC power from the retractable switch, the EV charging stand, and the secondary battery of the EV is sent as it is to the temporary relay device 112 of another layer. It is configured. Therefore, each temporary power relay device 112 can have the same configuration, can be installed individually according to the needs of a specific embodiment, and the temporary power relay device 112 can be appropriately installed. It can be relocated to supply power.

図３は、本実施形態で使用する延長ケーブル１１３の実施形態を示す。図３に示すように、延長ケーブル１１３は、電線２１０の両端にＥＶ用コネクタ２０３と、ＥＶ用コネクタ２０２とが接続されている。延長ケーブル１１３は、ＥＶ充電用の電力システムを使用する場合、充電ポストと、ＥＶとを接続する形式を有する充電ケーブルを使用することができる。また、図１に記載したように商用電源からの電力供給を行う場合には、既存の電線をＥＶ用プラグ２０３、３０３に接続し、適切電力供給を行うように構成することができる。 FIG. 3 shows an embodiment of the extension cable 113 used in the present embodiment. As shown in FIG. 3, in the extension cable 113, the EV connector 203 and the EV connector 202 are connected to both ends of the electric wire 210. When using a power system for EV charging, the extension cable 113 can use a charging cable having a form of connecting the charging post and the EV. Further, when power is supplied from a commercial power source as described in FIG. 1, existing electric wires can be connected to EV plugs 203 and 303 to be configured to appropriately supply power.

図４は、本実施形態の仮設用継電装置１１２の他の実施形態を示す。図２に示した実施形態では、筐体にＥＶ用プラグが設けられていたところ、図４に示す実施形態では、ＥＶ用プラグ２０１、２０４は、仮設用継電装置１１２から電線を介してブレーカー２０３に接続されており、その他の機能は、図２に示した仮設用継電装置１１２と同一である。図４に示した実施形態では、従来使用されていた配電盤に対して最小の加工で本実施形態の仮設用継電装置１１２とすることができ、従来資源を有効利用することが可能となる。

FIG. 4 shows another embodiment of the temporary power relay device 112 of this embodiment. In the embodiment shown in FIG. 2, where E V plug is provided on the housing, in the embodiment shown in FIG. 4, EV plug 201 and 204, the temporary use relay device 112 through an electric wire It is connected to the breaker 203, and other functions are the same as those of the temporary power relay device 112 shown in FIG. In the embodiment shown in FIG. 4, the temporary power relay device 112 of the present embodiment can be obtained with the minimum processing with respect to the switchboard conventionally used, and the conventional resources can be effectively used.

図５は、本実施形態の仮設用継電装置１１２の他の使用態様５０２を示した図である。なお、説明の便宜上、建造物１１０とＥＶ５０２の大きさは、変更して示している。鍛造物１１０には、本実施形態の仮設用継電装置１１２が配置されていて、仮設用継電装置１１２には、ＥＶの二次電池から電力が供給されている。ＥＶ５０２からの直流電流は、引出しケーブル５０１により、電力切替装置５０３に供給されている。電力切替装置５０３は、ＥＶ５０２からの電力を、例えば２００Ｖ３相交流に変換し、仮設用継電装置１１２に送付する。 FIG. 5 is a diagram showing another usage mode 502 of the temporary power relay device 112 of the present embodiment. For convenience of explanation, the sizes of the building 110 and the EV 502 are shown changed. The temporary power relay device 112 of the present embodiment is arranged on the forged product 110, and power is supplied to the temporary power relay device 112 from the secondary battery of the EV. The direct current from the EV 502 is supplied to the power switching device 503 by the extraction cable 501. The power switching device 503 converts the power from the EV 502 into, for example, 200V three-phase alternating current, and sends it to the temporary relay device 112.

なお、電力切替装置５０３としては、上述した特開２０１８−１０７８７９号公報に記載された電力切替装置を使用することができる。図５に示した仮設用継電装置１１２は、ＥＶ用コネクタを介して供給電力を受け取り、仮設用継電装置１１２が内蔵する電力切替装置２０５により、各階負荷２０６の要求に適合した電力に変換し、各階負荷２０６に供給する。 As the power switching device 503, the power switching device described in JP-A-2018-107879 described above can be used.

Then, it is supplied to the load 206 on each floor.

図５の実施形態によれば、建造物１１０の側に商用電力が無い場合や、商用電力を使用するまで電力需要が大きくない場合等、効率的に建造物１１０の施工のための電力を供給することが可能となり、施工性も改善することができる。 According to the embodiment of FIG. 5, when there is no commercial power on the side of the building 110 or when the power demand is not large until the commercial power is used, the power for the construction of the building 110 is efficiently supplied.
