Claims

[Scope of utility model registration request]

The main pipes on the transformer side and the busbar side are drawn out from both longitudinal ends of the grounded tank-type horizontal circuit breaker, respectively, and the main circuit on the transformer side is equipped with a current transformer, a grounding switch, and a bushing. In a gas-insulated switchgear, the main circuit on the side of the transformer is provided with a current transformer, a bushing, a disconnector, and a grounding switch, and further includes a busbar and a lightning arrester for connecting devices. The bushing is disposed substantially upward on the upper surface of one longitudinal end of the circuit breaker, and between the bushing and the circuit breaker, an earthing switch, a lightning arrester branch busbar, and a current transformer are constructed in this order from the circuit breaker side. A gas-insulated switchgear characterized in that the other end of the circuit breaker is connected to a bus bar through bushings, and an internal current transformer, a disconnector, and a grounding switch are connected in that order to the bus bar.
