Claims

[Scope of utility model registration request]

a substantially rectangular box-shaped container filled with insulating gas; a three-phase switchgear configuration device housed in the container;
a power receiving lead-in section consisting of an aerial bushing or a cable head; a transformer connection section for connecting the device to a transformer;
3-phase with connection busbars connected to other adjacent equipment
In the circular gas insulated switchgear, the power receiving lead-in part is disposed at one end in the longitudinal direction of the container, and the connection bus bar is led out from the other end in the longitudinal direction of the container, and the connection bus bar is arranged at right angles to the longitudinal direction of the container. 1. A three-phase, channel-type gas insulated switchgear, characterized in that the transformer connection portion is disposed on a side surface.
