Abstract

A gas insulated switchgear equipment in which three circuit breakers are electrically connected in series between two main bus bars. The two main buses are parallelly mounted on a fixing base. The three circuit breakers are arranged on one side of the main buses and aligned in the axial direction of the main buses. Connecting buses for electrically connecting the circuit breakers are provided on one side of the circuit breakers where the main bus bars are also disposed. Thus, the circuit breakers are accessible from the other side thereof for their maintenance and inspection and the equipment mounting area can be minimized because the main buses are disposed in parallel.
