１が装着されている。In FIG. 1, inside the tank 1 indicated by the two-dot chain line,
The contents of the transformer, consisting of the core 7, winding 6, core fasteners 8, line leads 9, and tap leads 10, are suspended from the cover 3 via the contents suspension bolts 4, and the on-load tap changer 1
1 is installed.
１２はタツプリード１０のタップリード絶縁補強物で、
第３図に示すように数本の平角線を一体に重ね合わせた
タツプリード１０を絶縁しており、負荷時タップ切換器
１１から離れた位置の巻線６のタツプリード１０を他相
巻線に対し絶縁している。12 is a tap lead insulation reinforcement of the tap lead 10;
As shown in Fig. 3, a tap lead 10 made of several rectangular wires stacked together is insulated, and the tap lead 10 of the winding 6 located away from the load tap changer 11 is connected to the other phase winding. Insulated.

続されている。Further, the line lead 9 is pulled out from each phase winding 6 and supported by line lead supports 13 fixed to the cover 3 at a plurality of locations between the line lead 9 and the bushing 2, and then pulled out from the winding 6 as shown in the figure. After that, it is raised upward, and after being extended in the horizontal direction, it is guided downward again and connected to the bushing 2.
尚、５は中身吊りボルトである。上記従来の構造におい

インリードの支持構造を簡略化できる負荷時タップ切換
変圧器を提供することにある。In addition, 5 is a bolt for hanging the contents. In the above-mentioned conventional structure, the line lead 9 is raised upward, extended horizontally, and then guided downward again, which increases the length of the line lead and increases the cause of dielectric breakdown problems. Since the line lead support 13 is attached, there is a drawback that the line lead support structure is complicated.The purpose of the present invention is to eliminate the above drawback, shorten the length of the line lead, and reduce the cause of dielectric breakdown trouble. An object of the present invention is to provide an on-load tap change transformer that can simplify the support structure of line leads.

延ばし、タップリード絶縁補強物にラインリード方向に
延びる複数のラインリード支持物を取付け、ラインリー
ド支持物にラインリードを取付けることにある。In the on-load tap-changing transformer of the present invention, a tap-lead insulation reinforcement that insulates the tap lead is extended to the tap-changer, a plurality of line-lead supports extending in the line lead direction are attached to the tap-lead insulation reinforcement, and the line lead is It consists in attaching the line lead to the support.
以下本発明の負荷時タップ切換変圧器の一実施例を、従
来と同部品は同符号で示し概略構造は従来とほとんど同
様なのでその説明を省略し第２図により説明する。Hereinafter, one embodiment of the on-load tap-changing transformer of the present invention will be explained with reference to FIG. 2, in which the same parts as in the conventional one are denoted by the same reference numerals, and the schematic structure is almost the same as the conventional one, so the explanation thereof will be omitted and will be explained with reference to FIG.
タップリード絶縁補強物１２は負荷時タップ切換器まで
延長している。The tap lead insulation reinforcement 12 extends to the on-load tap changer.
タップリード絶縁補強物に複数のラインリード支持物１
３を紐で結んで取付ける。Multiple line lead supports 1 on tap lead insulation reinforcement
Attach by tying 3 with a string.
複数のラインリード支持物１３は、ラインリード９方向
に延びていると共に、その高さ寸法はプツシング２側か
ら符号６の方向に行くにしたがい順次低くなっている。The plurality of line lead supports 13 extend in the direction of the line lead 9, and their heights decrease successively from the pushing 2 side toward the direction 6.
そして、ラインリード９はラインリード支持物１３に支
持されている。The line lead 9 is supported by a line lead support 13.
このようにラインリード９は、負荷時タップ切換器１１
部分まで延長されたタツプリード絶縁補強物１２を介し
取り付けられたラインリード支持物１３により支持され
るので、カバー３からの支持が不要となり、その支持構
造がきわめて簡単となる。In this way, the line lead 9 connects to the on-load tap changer 11.
Since it is supported by the line lead support 13 attached through the tapped lead insulating reinforcement 12 that extends to the section, support from the cover 3 is unnecessary, and its support structure becomes extremely simple.
更に、第３図からも明らかなように、ラインリード９の
長さを最短にできるので絶縁破壊トラブル要因を減ずる
ことができる。Furthermore, as is clear from FIG. 3, since the length of the line lead 9 can be minimized, the causes of dielectric breakdown troubles can be reduced.
