由于煤矿生产系统安装的异步电机之间有联锁保护,所以要求协调一致。如其中一台电机出现故障,会依靠电器闭锁设定,做出相应动作并发出信号,引起操作人员注意。由于电器闭锁是由电器辅助节点串并联构成的,节点多,控制线路复杂,以及电机的分布又是按照工序的要求而散布在整个生产 Due to the interlock protection between asynchronous motors installed in the coal mine production system, harmonization is required. If one of the motors malfunctions, it will rely on the setting of the electrical lock to make the corresponding action and send a signal, causing the operator’s attention. As the electrical equipment is closed by the electrical auxiliary nodes in series and parallel, more nodes, the control circuit is complex, and the distribution of the motor is in accordance with the requirements of the process and spread throughout the production
