自动控制系统中间继电器的检查项目与试验方法

Inspection Items and Test Methods of Electric Relay for Automatic Control System Control

中间继电器作为信号输出的执行放大、扩展元件,在自动控制系统中扮演着重要的角色,依照设备定期检测制度的规定,应定期对设备的工作状态进行必要的检查试验,但在现场工作中,中间继电的检测是一个容易被忽视薄弱的环节。本文从现场的试验出发,对中间继电器的检测项目和试验方法进行了总结,便于日常维护中开展对继电器的检测工作。

The intermediate relay acts as a signal output to perform amplification and expansion of components,and plays an important role in the automatic control system.In accordance with the provisions of the regular inspection system of the equipment,the necessary inspection and test of the working status of the equipment should be conducted periodically.However,in the field work,the detection of intermediate relays is a link that is easily overlooked and weak.This article starts from the test of the scene,summarizes the detection items and test methods of the intermediate relay,and facilitates the detection of the relay during routine maintenance.
