PURPOSE: An operating mechanism of a vacuum circuit breaker in a gas insulation switch is provided to perform an operation of a circuit breaker mechanism by operating a vacuum circuit breaker with a mechanical link device. CONSTITUTION: A main shaft(12) is rotated and driven by an operation of a circuit breaker mechanism(10). The rotary driving force of the main shaft(12) is transmitted to an operating shaft(90) through a circuit breaker speed control unit. The circuit breaker speed control unit includes a plurality of rotary arms(14,92) connected to the main shaft(12) and the operating shaft(90), a plurality of control links(20A,20B) connected to the rotary arms(14,92), and a control nut(30) connected to the control links(20A,20B) in order to control a hinge interval of the control links(20A,20B). A plurality of operating lever is installed at the operating shaft(90). An insulating link(100) is connected to a lever(110) of the vacuum circuit breaker(120).
