ーサ１２ａ，１２ｂによって形成されている。The busbar of such a switchgear is based on a gas division grounded tank in which both ends of a grounded tank are sealed with insulating spacers and a conductor is housed in the tank together with an insulating gas. Conventional Gas Sectional Grounding Tank 1 As shown in FIG. 1, a grounding tank 11 filled with insulating gas includes a conductor 17 housed inside, an insulating spacer 12a that supports insulation between the conductor and the ground, and 12b.

7 and the grounding tank 11, an arc 13 is generated, and this arc 13 is driven by the electromagnetic car 4 to the end of the inner wall of the grounding tank 11, where the legs of the arc are If the hole 16 remains in the grounded tank 11, there is a risk of a serious accident. The object of the present invention has been made in view of the above points, and is to provide a gas insulated switchgear equipped with a gas division grounded tank that can prevent damage to the tank due to arcing in the event of a ground fault.
In order to achieve the object of the present invention, a high melting point metal tube is provided at both ends of the inner wall surface of the grounded tank.
以下本発明を第２図に示す実施例を参照して説明する。The present invention will be explained below with reference to the embodiment shown in FIG.

が高いので金属消耗量が少ない。The same parts as in FIG. 1 are given the same symbols. As shown in FIG. 2, a grounding tank 11 filled with an insulating gas such as SF6 gas includes a conductor 17 housed inside and insulation spacers 12a and 1 for maintaining insulation between the conductor and the ground.
Refractory metal tubes 20a and 20b made of a high-melting metal member are attached to both ends of the inner wall surface of the tank 2b and the grounded tank 11. The high melting point metal member is made of titanium or heat-resistant steel, for example, which has a higher melting point than the material of the grounded tank, such as iron or aluminum, and the high melting point metal cylinders 20a and 20b are formed in an annular shape. In such a configuration of the present invention, when a ground fault occurs inside the grounded tank, the arc is driven to the end of the grounded tank 11 by electromagnetic force, and the legs of the arc stay on the metal cylinder 20a or 20b. Or, a part of 20b is melted, but since titanium or heat-resistant steel has a high melting point, the amount of metal consumption is small.

供することができる。Therefore, the legs of the arc do not reach the inner wall surface of the grounded tank 11, and there is no risk of damaging the grounded tank 11.
As described above, according to the present invention, by providing high melting point metal cylinders having a higher melting point than the ground material of the grounded tank at both ends of the inner wall surface of the grounded tank, when a ground fault occurs in the gas division grounded tank, the tank of the grounded tank Since damage to the ground tank due to ground fault arc can be prevented without increasing the thickness of the wall, it is possible to provide a gas insulated switchgear equipped with an economical gas sectional ground tank.
