Abstract

PURPOSE:To miniaturize a gas insulation switchgear by arranging service- entrance units and switches in such a way that the units and switches are respectively collected closely to each other. CONSTITUTION:A main and auxiliary service-entrance units 3a and 3b are constituted by respectively connecting disconnecting switches 1 and breakers 2. The units 3a and 3b are arranged in parallel with each other in the same direction. The first to third switches 4a-4c are arranged in parallel with each other in the direction perpendicular to the direction in which the units 3a and 3b are arranged. Since the first to third switches 4a-4c are collected relatively closely to each other, lengths of cable pits 18 can be reduced and, at the same time, the entire body of this gas insulation switchgear can be miniaturized.
