电动机现场指示灯干扰问题的解决方案

Solution for interfered field indicator light of electromotor

为消除感应电流对电动机指示灯的干扰,在现场操作柱中增加欧姆龙继电器,通过欧姆龙继电器的通断来控制指示灯,消除感应电流干扰。该方式改造简单,运行成本低,控制效果明显。

In order to eliminate the interference of induced current on the indicator light of electromotor, OMRON relay was added to the field operation column. The indicator light was controlled by the OMRON relay, and thus the interference of the induced current was eliminated. The reform was simple, and operation cost was tow, but control effect was good.
