熔断器和热继电器在电气线路中的使用

在电动机控制接线中，主电路中装有熔断器，为什么还要加装热继电器?它们各起何作用，能否互相代替?而在电热及照明线路中，为什么只装熔断器而不装热继电器?

     答:熔断器在电气线路中主要起短路保护和严重过载保护作用，而热继电器主要用于过载保护.两者不能互为代用，但可以互为补充.如果用熔断器作电动机的过载保护，为了防止电动机在启动过程中熔断器熔断，熔断器熔体的额定电流一般应取电动机额定电流的2. 5~3倍，这样即使电动机长时间过负荷50%，熔断器也不会熔断，而电动机可能因长时间过负荷而烧坏.所以不能用熔断器作过负载保护.而热继电器是利用电流的热效应来工作的，由于热惯性的影响，尽管发生短路时电流很大，也不可能使热继电器立即动作，这样就延长了短路故障的影响时间，对供电系统及用电设备会造成危害.所以也不能用热继电器作为短路保护.

对于电热及照明设备，由于负载的性质不同于电动机的拖动负载，一般来说，它们不会出现过负载现象，所以，一般不装备热继电器，而只装备熔断器，主要起短路保护作用.
