<p>PURPOSE: To obtain a gas insulated switchgear comprising an arrester and a section for disconnecting the arrester from the power supply side, disposed in a tank, wherein the overall size is reduced by simplifying the structure of disconnecting section. CONSTITUTION: A disconnecting section D comprising a fixed contact 5 and a movable contact is formed on the power supply side of an arrester 1. The fixed side contact 5 is fixed to the upper part of a tank through a supporting insulator 2 whereas the movable side contact is disposed on the power supply side of the arrester 1. The disconnection section is opened/closed by moving a straight advance sliding shaft 6, disposed on the ground side, up and down through a straight advance operating means 20.</p> |
