Abstract

본 발명은 부하전원 차단장치에 관한 것으로, 종래에는 부하구동소자가 쇼트되었을 경우 사용자가 전원을 차단하지 않는한 계속 부하가 온됨에 따라 부하가 과열되어 화재의 위험성이나 제품의 수명 및 안정성에도 치명적인 영향을 줄 수 있는 문제점이 있었다. 따라서 본 발명은 부하구동소자에 이상이 있어 부하가 온되지 않는 상황에도 부하로부터 이상전류가 검출되면 전원을 차단하여 화재의 위험을 방지할 수 있도록 한 효과가 있다.The present invention relates to a load power cut-off device, and in the related art, when the load driving device is shorted, the load is overheated as the load is continuously turned on unless the user cuts off the power, and thus, the load is overheated. There was a problem that could give. Therefore, the present invention has the effect of preventing the risk of fire by shutting off the power supply when an abnormal current is detected from the load even in a situation where the load driving device is abnormal and the load is not turned on.
