复合继电器控制的启动电路维修

Maintenance of starting circuit controlled by compound relay

对于带有复合继电器的启动电路,首先要清楚其结构组成,其次要理顺其线路连接关系,电路控制关系,这样才能明了整个启动过程与工作原理,这样就可依照实际产生的故障现象,分析故障原因,使用相关工具进行检测,排除故障。

For the starting circuit with composite relay,first of all,we need to know its structure and composition,secondly,we need to straighten out its connection relationship between lines and circuit control relationship,so that we can understand the whole starting process and working principle,so that we can analyze the causes of the failure according to the actual fault phenomenon,and use relevant tools to carry out inspection.
