<p>PURPOSE:To make a gas insulation switching device light weight and compact by mounting a current transformer supporting plate to a plurality of protrusions which are provided at the inner periphery surface of container flange part. CONSTITUTION:A plurality of protrusions 21 are provided at the inner periphery surface of a flange part 19 of a container which is connected to a target equipment 17 of a current transformer container 9 with a specified amount of distance between them and a current transformer supporting plate 22 is mounted to these protrusions 21. In this case, the current transformer supporting plate 22 is stored within a gas 18 so that it is not restricted by regulations of a pressure container, its thickness may be the minimum which is required for supporting a current transformer 8. Thus, a current transformer supporting plate 22 is stored within the gas 18 and a recessed part is provided at the gas- side protruded part of a container flange 19 to retain a space for storing the main unit of the current transformer 8. Therefore, the size of a gas insulation switching device can be minimized and made light weight.</p> |
