| description | The invention relates to the field of switch equipment and particularly relates to a circuit breaker and a hydraulic linked operating mechanism thereof. The hydraulic linked operating mechanism comprises a hydraulic control unit and operating units in one-to-one correspondence with all phases of the circuit breaker; each operating unit comprises a power master valve in which a master valve signal oil port is formed; a hydraulic control signal oil port communicating with the master valve signal oil port to introduce high-pressure signal oil to the master valve signal oil port and making the master valve signal oil port communicate with a low-pressure oil tank is formed in the hydraulic control unit which is a mater hydraulic control unit; and the master valve signal oil port of each power master valve is simultaneously connected with the hydraulic control signal oil port of the master hydraulic control unit so as to be simultaneously controlled by the master hydraulic control unit. The power master valve corre |
