GAS-INSULATED SWITCHGEAR

摘要

A gas-insulated switchgear which can suppress heat generation from a pressure vessel. A nonmagnetic conductive material having a conductivity higher than that of a pressure vessel is arranged on the inside and outside of the pressure vessel along a main bus and fixed through the flange of the pressure vessel. With such an arrangement, an eddy current generated when the main bus conducts a current flows through the conductive material having a conductivity higher than that of the pressure vessel, and the circulation path of the eddy current is formed by a channel including the conductive material. Consequently, the eddy current flowing to the pressure vessel is reduced and temperature rise of the pressure vessel can be suppressed.
