The fixed contact hanging conductor of the pantograph type disconnect switch used in the aluminum pipe busbars of power generation and substations is fixed with aluminum pipe mounting brackets to provide flexibility against the lateral vibration load when the disconnect switch is turned on. The contact terminals are connected by welding using a flexible plate. The flexible plate is a thin aluminum laminate, and the entire flexible plate is covered with an aluminum cover to prevent corona.

撓みがふえる。 By the way, when it comes to a large-capacity, for example, 8000A hanging conductor, in the conventional design, the width, number, and weight of the flexible plate 3 increase significantly. As a result, the wind pressure load increases, and the bending in the center of the aluminum pipe increases due to the increased weight.

可撓性を保持することができる。 If a flexible plate is used as a large-capacity device as described above, the number of thin aluminum plates forming the flexible plate will increase, and the width will also increase. Also, from the perspective of preventing corona, an aluminum cover is essential, and heat will accumulate inside. By making air circulation holes in the aluminum cover and painting the flexible plate black, heat dissipation from the flexible plate is sufficient, making it possible to design a smaller flexible plate. Flexibility can be maintained.

溶接によつて接続される。 As already explained with reference to FIG. 1, a flexible plate 3 made of a plurality of thin aluminum laminates is installed between the aluminum pipe fitting 1, especially the aluminum seat plate 8 which is a part of it, and the fixed contact terminal 2. are connected by welding. Reference numeral 6 denotes an aluminum cover that is placed over the outside of the aluminum cover 6, and a plurality of air circulation holes 7 are formed in the upper part of the aluminum cover 6. This aluminum cover 6 is passed through the flexible plate 3, and the end of the aluminum cover 6 is attached to a seat plate 8 which becomes a part of the aluminum pipe fitting 1.
, and tighten the other end integrally with the fixed contact terminal 2 using bolts and nuts 9. The aluminum pipe fitting 1 and the conductor 5 made of an aluminum pipe are connected by welding.
前記空気流通穴７は熱空気の流通を良好とする
ため、特に、上端側に設けることが望ましく、図
示のように楕円形の場合、例えば径250mm、厚み
10mmのアルミカバーの上方側面に50×125への楕
円穴を８ケ所あける。 In order to improve the circulation of hot air, the air circulation hole 7 is particularly preferably provided on the upper end side, and in the case of an oval shape as shown in the figure, for example, the diameter is 250 mm and the thickness is 250 mm.
Drill eight 50x125 oval holes on the upper side of the 10mm aluminum cover.
また第３図イに示すように、アルミカバー６の
上端部に凹凸部１０を設けて、取付けによつて空
気流通穴としてもよい。 Further, as shown in FIG. 3A, an uneven portion 10 may be provided at the upper end of the aluminum cover 6 to form an air circulation hole when attached.

ともに10mm以上とることによつて空気流通路を形
成しても良い。 In addition, as shown in Figure 3B, the gap l between the aluminum cover 6 and the aluminum pipe fitting 1 and the gap l' between the aluminum cover 6 and the seat plate 8 are both 10 mm or more. An air flow passage may also be formed.
第２図ロに点線で示すように、薄いアルミの積
層よりなる可撓板３は黒色塗装１１が施されてい
る。 As shown by the dotted line in FIG. 2B, the flexible plate 3 made of a thin aluminum layer is painted black 11.

を黒色塗装することにより、ふく射係数比は0.9
以上となり、放熱が非常によくなる。 In conventional flexible plates, the surface has a glossy finish due to mechanical processing, the radiation coefficient ratio of the surface is about 0.2 to 0.3, and heat dissipation is poor. On the other hand, by painting the flexible plate black, the radiation coefficient ratio is 0.9.
As a result, heat dissipation is greatly improved.

As explained above, in the present invention, the surface of the flexible plate that generates heat when energized is painted black, and the hot air trapped inside the aluminum cover is sufficiently dissipated to the outside world through holes provided in the aluminum cover. This makes it possible to reduce the size of the flexible plate in order to suppress temperature rises, and by reducing the size of the flexible plate design, it is possible to give the flexible plate its original function and reduce its weight. This makes it possible to obtain a hanging conductor that has superior performance and is more economical than conventional ones.
