た機器の配置構成が必要となっている。(Prior Art) A gas-insulated switchgear is a container filled with SF 6 gas, which has excellent insulation and arc extinguishing properties, and contains a circuit breaker, a disconnector, etc. It is configured. This type of switchgear can be configured to be significantly smaller than an air-insulated switchgear. In particular, in recent years, gas-insulated switchgears that can be downsized have been widely used in substations due to a remarkable skyrocketing underground.
Therefore, rationalization of the insulation design is required as a factor that greatly contributes to miniaturization, and it is necessary to fully consider the sliding powder generated with the opening / closing operation of the switch, especially the arrangement and layout of the equipment. Is needed.

３に設けられている。FIG. 5 shows an example of equipment arrangement of a gas-insulated switchgear based on JP-A-60-187216. That is, the trackside disconnector
Below the fixed electrode 1 and the movable electrode 2 of the DS1, a support insulator 4 for supporting the conductor 3 on the movable electrode side is arranged,
Further, a fixed electrode 5 of a ground switch is provided on the conductor 3 below the fixed electrode 5.

As a result, the supporting insulator 4 is increased in size, and the container for accommodating the supporting insulator 4 is also enlarged.
