Abstract: PURPOSE: A device for preventing insulation breakdown of a gas insulation switching device and a preventing method thereof are provided to prevent accidents by preventing a wire point from recovering gas or a ground switching device form being inserted due to mal-operation of a worker. CONSTITUTION: A communication part(420) receives the current value of Line-PT and BUS-PT from the PT panel of a gas insulation switching device. The communication part receives the connecting and disconnecting states of a first disconnector, a second disconnector, and a circuit breaker from the control panel of the gas insulation switching device. A determining part(440) determines the states of the wires of the first disconnector, the second disconnector, the circuit breaker, and the ground switching device. A control part(460) controls to output the states of the first disconnector, the second disconnector, the circuit breaker, and the ground switching device determined at the determining part. An output part(480) outputs the states of the first disconnector, the second disconnector, the circuit breaker, and the ground switching device according to the control of the control part.
