この発明社ガス絶縁母線等のガス絶縁電気装置における
容器の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a container for a gas insulated electrical device such as a gas insulated busbar.
第１図社従来のこの種装置の構造を示す縦断面図である
。FIG. 1 is a vertical cross-sectional view showing the structure of a conventional device of this type.
この図において（１）は筒状の容器で、軽量化および渦
電流損低減のため、アルミニウムまたはその合金により
構成されている。In this figure, (1) is a cylindrical container, which is made of aluminum or an alloy thereof in order to reduce weight and reduce eddy current loss.

た母線等の導体である。C) is an insulating spacer (3) placed at regular intervals in the container. A conductor such as a bus bar is supported by the insulating spacer.
なお１容器（１）の内部には絶縁ガスが充填されて−る
。Note that the inside of one container (1) is filled with an insulating gas.

その温度によりアルミニウム製の容器（１）を溶融し貫
通破壊する恐れがある。The conventional device is constructed as described above, but if a flash fault occurs between the conductor O) and the container (1) for some reason, an arc will occur between the two, but this arc It moves left and right depending on the current direction. However, if it touches the insulating spacer (2) and its creeping resistance decreases, even if the current direction of the conductor changes, it will remain near the Ark company's insulating spacer, and the temperature will eventually melt the aluminum container (1) and cause it to break through. There is a fear.

以下、ＦＩ！ＪＫ示すこの発明の一実施例について説明
する。The present invention aims to eliminate such drawbacks and provide a device that does not impair eddy current loss reduction and weight reduction.Hereinafter, FI! An embodiment of this invention shown by JK will be described.

溶融点約６００℃）で形成する。That is, as shown in Fig. 2', the material of the container is different between the part located near the insulating spacer and the other parts. The portion (11) is made of stainless steel (melting point approximately 1600°C), which is a non-magnetic material and has a higher melting point than aluminum or its alloy.The other portion (12) is made of aluminum or its alloy (as in the past).
It is formed at a melting point of approximately 600°C.
その他の構成は従来の装置と同様である。The rest of the configuration is similar to the conventional device.

その合金の部分（１２）とは７ランジによるボルト結合
としても同様な効果が期待出来る。Note that the same effect can be expected even if the stainless steel part (11) and the aluminum or aluminum alloy part (12) are connected by bolts using seven langes.

損なうこともなく実用上１すぐれたガス絶縁電This invention is constructed as described above, and since the part near the insulating spacer, which is a small part of the container, is formed of a material with a higher melting point than the other parts, the container will melt even if the arc stays near the insulating spacer. It is a gas insulated electrical conductor with excellent practical properties without sacrificing these characteristics, as it has no fear, has low eddy current loss, and can be used as a material for light meals.
