Abstract
The present invention provides a three-phase lumped together gas insulated switchgear, which is small-sized and simply constructed, including main busbar conductors and disconnectors connected to the main busbar conductors. In the gas insulated switchgear, phases of the main busbar conductors are respectively disposed on the vertexes of a triangle. Further, the axes of the disconnectors and disconnector movable side conductors, both of which correspond to three phases, are arranged between one phase of the main busbar conductor and the other two phases of the main busbar conductors so that the axes of the disconnectors for the busbars become parallel with each other. Furthermore, the movable side conductors are connected to the main busbar conductors. Because of the above construction, a circuit breaker and the busbars can be linked within the shortest possible distance to the disconnectors arranged between the circuit breaker and the busbars.
