<p>A gas insulated switchgear has: circuit breakers, circuit breaker vessels, first disconnector and maintenance earthning switches connected to first bus bars connected to circuit breaker vessels and also to main bus bars, second disconnector and maintenance earthning switches connected to second bus bars connected to the circuit breaker vessels, circuit breaker operating mechanisms, first and second disconnector and maintenance earthning switch operating mechanisms, and first and second disconnector and maintenance earthning switch operation links for linking the disconnector and maintenance earthning switches and the operating mechanisms for three phases. The second disconnector and maintenance earthning switch operation links are arranged so as to pass through inter-phases of the first bus bars and the operating panels of the circuit breaker operating mechanism and the first and second disconnector and maintenance earthning switch operating mechanisms of each phase are arranged on a common flat plane.</p> |
