Description

この発明は、変圧器の二次側リード線が断線した場合に、応急的に電力を供給するための変圧器用仮リード体および、これを使用した給電方法に関する。   The present invention relates to a temporary lead body for a transformer for temporarily supplying power when a secondary lead wire of a transformer is disconnected, and a power feeding method using the temporary lead body.

図３に示すように、変圧器１００は、箱型で上部が開口した本体１０２と、本体１０２の上部を覆う蓋１０３とを備えている。また、本体１０２の側壁内面には内部端子１０４が配設され、この内部端子１０４には、コイル（図示せず）に接続された内部リード線１０５が接続されている。一方、本体１０２の側壁外面には外部端子１０６が配設され、この外部端子１０６に二次側（低圧側）リード線１０１が接続されている。さらに、内部端子１０４と外部端子１０６とが接続されていることで、内部リード線１０５（コイル）と二次側リード線１０１とが、内部端子１０４と外部端子１０６とを介して導通接続されている。そして、二次側リード線１０１を引き込み線（低圧引き下げ、引き上げ線）に接続することで、二次側リード線１０１を介して引き込み線側（需要家側）に電力が供給されるものである。   As shown in FIG. 3, the transformer 100 includes a box-shaped main body 102 that is open at the top and a lid 103 that covers the top of the main body 102. An internal terminal 104 is disposed on the inner surface of the side wall of the main body 102, and an internal lead wire 105 connected to a coil (not shown) is connected to the internal terminal 104. On the other hand, an external terminal 106 is disposed on the outer surface of the side wall of the main body 102, and a secondary side (low voltage side) lead wire 101 is connected to the external terminal 106. Further, since the internal terminal 104 and the external terminal 106 are connected, the internal lead wire 105 (coil) and the secondary lead wire 101 are electrically connected via the internal terminal 104 and the external terminal 106. Yes. Then, by connecting the secondary lead wire 101 to the lead-in wire (low-voltage pull-down, pull-up wire), power is supplied to the lead-in wire side (customer side) via the secondary lead wire 101. .

このような変圧器１００の二次側リード線１０１が断線した場合、断線を改修する方法として、電線接続用のスリーブなどを用いて、断線した二次側リード線１０１に新たなリード線を接続する方法が知られている（例えば、特許文献１参照。）。   When the secondary-side lead wire 101 of such a transformer 100 is disconnected, a new lead wire is connected to the disconnected secondary-side lead wire 101 using a wire connection sleeve or the like as a method of repairing the disconnection. There is a known method (see, for example, Patent Document 1).

特開平１０−２５５８６５号公報Japanese Patent Laid-Open No. 10-255865

ところで、二次側リード線１０１が、その自重や風力などによって、外部端子１０６に接続されている根元で断線してしまう場合がある。一方、特許文献１の技術では、断線した二次側リード線１０１と新たなリード線とを重ねてスリーブで圧接、接続するため、断線した二次側リード線１０１が、外部端子１０６から１０ｃｍ程度残っていなければ、新たなリード線を接続することができない。   By the way, the secondary side lead wire 101 may be disconnected at the root connected to the external terminal 106 due to its own weight or wind force. On the other hand, in the technique of Patent Document 1, since the disconnected secondary side lead wire 101 and a new lead wire are stacked and pressed and connected with a sleeve, the disconnected secondary side lead wire 101 is about 10 cm from the external terminal 106. If it does not remain, a new lead cannot be connected.

従って、二次側リード線１０１が外部端子１０６の根元で断線した場合、特許文献１の技術では、新たなリード線を接続して改修を行うことができない。この結果、変圧器１００を交換するしか改修方法、電力供給方法がなく、停電状態が長期化してしまうおそれがある。   Therefore, when the secondary lead wire 101 is disconnected at the base of the external terminal 106, the technique of Patent Document 1 cannot be repaired by connecting a new lead wire. As a result, there is only a replacement method and a power supply method for replacing the transformer 100, and there is a possibility that the power outage state will be prolonged.

そこでこの発明は、変圧器の二次側リード線が根元で断線した場合であっても、確実に電力を供給することを可能にする変圧器用仮リードおよび給電方法を提供することを目的とする。   Therefore, an object of the present invention is to provide a temporary lead for a transformer and a power feeding method that can surely supply power even when the secondary side lead wire of the transformer is disconnected at the base. .

ここで、変圧器１００は、図３に示すように、箱型で上部が開口した本体１０２と、この本体１０２の上部を覆う蓋１０３とを備える。また、図１に示すように、本体１０２の開口端縁１０２ａに接する蓋１０３の内面には、弾性を有し変形自在なゴムパッキン（パッキン）１０３ａが配設されている。   Here, as shown in FIG. 3, the transformer 100 includes a main body 102 that is box-shaped and has an upper opening, and a lid 103 that covers the upper portion of the main body 102. Further, as shown in FIG. 1, an elastic and deformable rubber packing (packing) 103a is disposed on the inner surface of the lid 103 in contact with the opening edge 102a of the main body 102.

本体１０２の側壁内面には内部端子１０４が配設され、この内部端子１０４には、コイル（図示せず）に接続された内部リード線１０５が接続されている。一方、本体１０２の側壁外面には外部端子１０６が配設され、内部端子１０４と外部端子１０６とが接続板１０７を介して接続されている。ここで、垂直に延びるボルト１０８が内部端子１０４に接続され、接続板１０７の挿入孔にボルト１０８が挿入され、ボルト１０８にナット１０９が締め込まれることで、接続板１０７が取り付けられている。   An internal terminal 104 is disposed on the inner surface of the side wall of the main body 102, and an internal lead wire 105 connected to a coil (not shown) is connected to the internal terminal 104. On the other hand, an external terminal 106 is disposed on the outer surface of the side wall of the main body 102, and the internal terminal 104 and the external terminal 106 are connected via a connection plate 107. Here, the vertically extending bolt 108 is connected to the internal terminal 104, the bolt 108 is inserted into the insertion hole of the connecting plate 107, and the nut 109 is tightened into the bolt 108, whereby the connecting plate 107 is attached.

また、外部端子１０６には二次側リード線１０１が接続され、内部リード線１０５（コイル）と二次側リード線１０１とが、内部端子１０４と接続板１０７と外部端子１０６とを介して導通接続されている。そして、二次側リード線１０１を引き込み線（低圧引き下げ、引き上げ線）に接続することで、変圧器１００から引き込み線側（需要家側）に電力が供給されるようになっている。   Further, the secondary side lead wire 101 is connected to the external terminal 106, and the internal lead wire 105 (coil) and the secondary side lead wire 101 are electrically connected through the internal terminal 104, the connection plate 107, and the external terminal 106. It is connected. And by connecting the secondary lead wire 101 to the lead-in wire (low-voltage pull-down, pull-up wire), electric power is supplied from the transformer 100 to the lead-in wire side (customer side).

導体２は、導電性で、変圧器１００の本体１０２の開口端縁１０２ａに係合する係合部２１を有し、係合部２１が開口端縁１０２ａに係合した状態で、一端部２ａが本体１０２内に位置し、他端部２ｂが本体１０２外に位置するように形成されている。   The conductor 2 is electrically conductive and has an engaging portion 21 that engages with the opening end edge 102a of the main body 102 of the transformer 100. With the engaging portion 21 engaged with the opening end edge 102a, the one end 2a Is located in the main body 102 and the other end 2 b is located outside the main body 102.

具体的には、薄い帯板状の銅板で構成され、図２に示すように、略「７」字状（鉤型、フック状）に形成され、その曲げ部が係合部２１となっており、係合部２１の内側間隔Ｇは、変圧器１００の本体１０２の側壁の厚みよりもやや大きく設定されている。そして、係合部２１が開口端縁１０２ａに係合、嵌合した状態で、一端部２ａ側（短片側）が本体１０２の側壁内面に沿って下方に延び、一端部２ａが内部端子１０４の上方に位置し、他端部２ｂ側（長片側）が本体１０２の側壁外面に沿って下方に延び、他端部２ｂが外部端子１０６の上方に位置するようになっている。   Specifically, it is formed of a thin strip-shaped copper plate, and is formed in a substantially “7” shape (saddle shape, hook shape) as shown in FIG. The inner gap G of the engaging portion 21 is set to be slightly larger than the thickness of the side wall of the main body 102 of the transformer 100. Then, in a state where the engaging portion 21 is engaged with and fitted to the opening edge 102 a, the one end 2 a side (short piece side) extends downward along the inner surface of the side wall of the main body 102, and the one end 2 a is connected to the internal terminal 104. The other end 2 b side (long piece side) extends downward along the outer surface of the side wall of the main body 102, and the other end 2 b is located above the external terminal 106.

また、図１に示すように、本体１０２の開口端縁１０２ａと蓋１０３とで係合部２１が挟まれた状態で、ゴムパッキン１０３ａの変形によって本体１０２の開口端縁１０２ａと蓋１０３とに隙間が生じないように、つまり、本体１０２と蓋１０３との密封性・気密性が確保されるように、導体２の厚みが設定されている。さらに、導体２の幅は、内部リード線１０５（コイル）側から所定の電流を流せるように設定されている。また、導体２には、その両端部２ａ、２ｂを除いて絶縁被覆が施されている。   In addition, as shown in FIG. 1, with the engagement portion 21 sandwiched between the opening edge 102 a of the main body 102 and the lid 103, the opening end edge 102 a of the main body 102 and the lid 103 are deformed by the deformation of the rubber packing 103 a. The thickness of the conductor 2 is set so that a gap is not generated, that is, the hermeticity and airtightness between the main body 102 and the lid 103 are ensured. Furthermore, the width of the conductor 2 is set so that a predetermined current can flow from the internal lead wire 105 (coil) side. In addition, the conductor 2 is provided with an insulating coating except for its both end portions 2a and 2b.

このような導体２の短片側の一端部２ａに、導電性の接続線３が接続されている。すなわち、一端部２ａに第１のボルト２１が取り付けられ（例えば、溶接され）、この第１のボルト２１に螺合されたナット２２、２３で挟持されることで、接続線３の基端部が接続されている。また、この接続線３の自由端部には、Ｃ字状（爪形）のコネクタ３１が接続され、後述するようにして、このコネクタ３１を介して内部端子１０４に接続可能となっている。   A conductive connection line 3 is connected to one end 2 a on the short piece side of the conductor 2. That is, the first bolt 21 is attached (for example, welded) to the one end 2a, and is clamped by the nuts 22 and 23 screwed to the first bolt 21, so that the base end of the connection line 3 Is connected. Further, a C-shaped (claw-shaped) connector 31 is connected to the free end of the connection line 3 and can be connected to the internal terminal 104 via the connector 31 as described later.

一方、導体２の長片側の他端部２ｂに、導電性の仮リード線４が接続されている。すなわち、他端部２ｂに第２のボルト２４が取り付けられ（例えば、溶接され）、この第２のボルト２４に螺合されたナット２５、２６で挟持されることで、仮リード線４の基端部が接続されている。また、仮リード線４の自由端部は、後述するように、引き込み線に接続可能となっている。   On the other hand, a conductive temporary lead wire 4 is connected to the other end 2 b of the long side of the conductor 2. That is, the second bolt 24 is attached (for example, welded) to the other end 2b, and is clamped by nuts 25 and 26 screwed into the second bolt 24, whereby the base of the temporary lead wire 4 is obtained. The ends are connected. Further, the free end portion of the temporary lead wire 4 can be connected to a lead-in wire as will be described later.

ここで、接続線３と仮リード線４とには、両端部を除いて絶縁被覆が施されている。また、接続線３の長さは、後述するようにしてコネクタ３１を内部端子１０４に接続できるように設定され、仮リード線４の長さは、二次側リード線１０１の初期長（断線前の長さ）と同等の長さに設定され、引き込み線に接続できるようになっている。   Here, the connecting wire 3 and the temporary lead wire 4 are provided with an insulating coating except for both ends. Further, the length of the connecting wire 3 is set so that the connector 31 can be connected to the internal terminal 104 as described later, and the length of the temporary lead wire 4 is the initial length of the secondary side lead wire 101 (before disconnection). It is set to a length equivalent to the length of the cable and can be connected to the lead-in wire.

さらに、第１のボルト２１とナット２２、２３とを覆う電気絶縁性の第１のキャップ５１と、第２のボルト２４とナット２５、２６とを覆う電気絶縁性の第２のキャップ５２とが、それぞれ着脱自在に設けられている。   Furthermore, an electrically insulating first cap 51 that covers the first bolt 21 and the nuts 22 and 23, and an electrically insulating second cap 52 that covers the second bolt 24 and the nuts 25 and 26 are provided. Are detachably provided.

次に、このような構成の変圧器用仮リード体１を使用した給電方法などについて説明する。   Next, a power supply method using the transformer temporary lead body 1 having such a configuration will be described.

まず、二次側リード線１０１が断線した場合、まず、変圧器１００の蓋１０３を開けて、図１に示すように、変圧器用仮リード体１の導体２の係合部２１を本体１０２の開口端縁１０２ａに係合、装着させる。次に、接続線３を内部端子１０４に接続する。すなわち、接続線３のコネクタ３１を内部端子１０４のボルト１０８に挿入した状態でナット１０９を締め込んで、ナット１０９と接続板１０７とでコネクタ３１を挟持する。これにより、仮リード線４と内部リード線１０５（コイル）とが、導体２と接続線３と内部端子１０４とを介して接続される。   First, when the secondary lead wire 101 is disconnected, first, the lid 103 of the transformer 100 is opened, and the engaging portion 21 of the conductor 2 of the transformer temporary lead body 1 is connected to the main body 102 as shown in FIG. Engage and attach to the opening edge 102a. Next, the connection line 3 is connected to the internal terminal 104. That is, the nut 109 is tightened in a state where the connector 31 of the connection line 3 is inserted into the bolt 108 of the internal terminal 104, and the connector 31 is sandwiched between the nut 109 and the connection plate 107. Thereby, the temporary lead wire 4 and the internal lead wire 105 (coil) are connected through the conductor 2, the connection wire 3, and the internal terminal 104.

次に、第１のボルト２１とナット２２、２３とに第１のキャップ５１を装着し、第２のボルト２４とナット２５、２６とに第２のキャップ５２を装着して、変圧器１００の本体１０２に蓋１０３を取り付ける。その後、仮リード線４の自由端部を引き込み線に接続する。   Next, the first cap 51 is attached to the first bolt 21 and the nuts 22 and 23, and the second cap 52 is attached to the second bolt 24 and the nuts 25 and 26. A lid 103 is attached to the main body 102. Thereafter, the free end portion of the temporary lead wire 4 is connected to the lead-in wire.

このようにして、変圧器用仮リード体１を配設した状態では、変圧器１００の内部リード線１０５（コイル）側と引き込み線とが、内部端子１０４と接続線３と導体２と仮リード線４とを介して導通接続され、変圧器１００から引き込み線側（需要家側）に電力が供給可能となるものである。   In this manner, in the state where the transformer temporary lead body 1 is disposed, the internal lead wire 105 (coil) side of the transformer 100 and the lead-in wire are connected to the internal terminal 104, the connection wire 3, the conductor 2, and the temporary lead wire. 4, and can be supplied with electric power from the transformer 100 to the lead-in line side (customer side).

以上のように、この変圧器用仮リード体１および給電方法によれば、既存の二次側リード線１０１を利用して電力供給するものではないため、二次側リード線１０１が根元で断線した場合であっても、確実に電力を供給することができる。しかも、導体２の係合部２１を本体１０２の開口端縁１０２ａに係合させ、接続線３を内部端子１０４に接続し、仮リード線４を引き込み線に接続するだけでよいため、容易、安全かつ迅速に電力を供給することが可能となる。   As described above, according to the temporary lead body 1 for a transformer and the power feeding method, power is not supplied using the existing secondary side lead wire 101, so the secondary side lead wire 101 is disconnected at the base. Even if it is a case, electric power can be supplied reliably. In addition, the engaging portion 21 of the conductor 2 is engaged with the opening edge 102a of the main body 102, the connecting wire 3 is connected to the internal terminal 104, and the temporary lead wire 4 only needs to be connected to the lead-in wire. It becomes possible to supply power safely and quickly.

この結果、二次側リード線１０１が根元で断線しても、変圧器１００を取り替えることなく早期に仮送電を行い、停電時間を大幅に短縮化することができる。また、柱上活線近接作業であるため、作業に必要な人員の削減が可能となる。   As a result, even if the secondary lead wire 101 is disconnected at the base, temporary power transmission can be performed early without replacing the transformer 100, and the power failure time can be greatly shortened. In addition, since the work is close to the live poles, it is possible to reduce the number of personnel required for the work.

しかも、変圧器用仮リード体１を配設しても、変圧器１００の本体１０２と蓋１０３とに隙間が生じないように、導体２の厚みが設定されているため、変圧器１００の気密性を確保して、変圧器１００の機能、性能を維持することができる。   Moreover, since the thickness of the conductor 2 is set so that no gap is generated between the main body 102 and the lid 103 of the transformer 100 even if the temporary lead body 1 for the transformer is disposed, the airtightness of the transformer 100 is set. And the function and performance of the transformer 100 can be maintained.

また、変圧器１００を取り替えて本送電を行い、変圧器用仮リード体１による仮送電が不要になった場合には、変圧器用仮リード体１を取り外すことで変圧器用仮リード体１を再利用することができ、経済的である。   In addition, when the transformer 100 is replaced and main power transmission is performed and the temporary power transmission using the transformer temporary lead body 1 is no longer necessary, the transformer temporary lead body 1 is removed to reuse the transformer temporary lead body 1. Can be economical.
