在自动控制电路中有以下保护环节，也是一般自动控制电路共有
的保护环节。
（1）短路保护 电机、电器和导线的绝缘损坏或发生故障时，可能
造成短路事故。很大的短路电流产生过热和电动力可能引起电器设备
损坏，甚至因此引起火灾，因此要求一旦发生短路故障时，控制电路
应能迅速地切断电路。
短路保护的常用方法是采用熔断器或断路器。这些保护装置不应受起
动电流的影响而误动作。所以要按熔断器、断路器的选择和整定要求进行。
（2）长期过载保护和断相保护
电动机长期超载运行，绕组温升将超过其允许值，造成绝缘材料变脆、
寿命缩短，严重时还会使电动机损坏。过载电流越大，达到允许温升
的时间就越短。常用的长期过载保护元件是热继电器。热继电器不能兼
作短路保护，因为发生短路时，它可能还来不及动作就已对电器设备
造成损坏了。
据统计，因断相运行而烧坏电动机的台数，在有些单位竟多达损坏电机
总台数的80%以上，所以电动机应该有断相保护的环节，也就是说要选用
带断相保护功能的热继电器。
