<p>In order to provide a good gas-insulated circuit breaker which is compact and easy in assembling and preparation, a gas-insulated circuit breaker 100 is constructed with a grounded encloser 104 enclosing insulation nature gas, a current interruption part having a fixed contactor 115 arranged in the grounded encloser 104 and a movable contactor 116 to be contacted with and to be separated from the fixed contactor 115, and an operating mechanism 101 to output a driving force to drive the movable contactor 116, wherein a grounded encloser side main rotating shaft 110 connected to the movable contactor 116 through a connection member and a main output shaft 102 for outputting a rotating force to actuate the movable contactor 116 through the grounded encloser side main rotating shaft 110 provided on the operating mechanism 101, are arranged on a coax so as to be coupled with a gear coupling 120, and the operating mechanism 101 is arranged almost under the grounded encloser 104. <IMAGE></p> |
