The present invention relates to an earthquake-proof device for a switchgear. the earthquake-proof device for a switchgear comprises: a lifting means mounted on a lower portion of a switchgear and having an air tube embedded therein; a compressor having an air inlet and outlet pipe installed to supply or discharge air to or from the air tube; and a control unit for controlling the operation of the compressor. when vibration occurs due to an earthquake or the like, air is automatically supplied to the air tube, so that longitudinal and transverse vibrations can be effectively and immediately attenuated.
본 발명은 수배전반용 내진 장치에 관한 것으로, 수내전반의 하부에 장착되고, 에어튜브가 내장된 승강수단; 에어튜브에 공기를 공급 또는 배출하도록 공기 유출입관이 설치된 컴프레서;와 컴프레서의 작동을 제어하는 제어부;를 포함하여 이루어짐으로써, 지진 등에 의한 진동 발생시 에어튜브에 공기가 자동 공급되어 종, 횡방향 진동이 효과적이면서 즉각적으로 감쇠될 수 있도록 한 것이다.
