ABSTRACT:
A gas-insulated switchgear is provided, which can be made smaller and causes less increase in length in the circuit direction, by means of an improvement to the layout configuration of the operating rod of a bus-use grounding switch. Operating rods of bus-use grounding switches are vertically disposed so as to be substantially perpendicular to the buses, and operating devices are disposed along an extension of the operating rods, respectively. Bus-use voltage transformers are horizontally disposed in such a manner that they vertically overlap each other, and are respectively connected in the circuit breaker direction of the buses.
