摘要
本文通过对剩余电流动作保护器的介绍与应用,并结合众多工程设计实例,提出了剩余电流动作保护器在几种常见情况下使用的必要性。剩余电流动作保护器在TN接地系统中对于工厂单相接地故障起到保护作用。在某些情况下,应使用带剩余电流保护功能的塑壳断路器进行电动机或线路保护。
Through the introduction and application of the Residual current operated protective device in this paper, combined with many engineering design examples, this paper puts forward the necessity of the use of residual current operated protective device in several common situations. Residual current operated protective device has protective effect on the single phase grounding fault in TN system.In some cases, the circuit breakers with residual current protection function should be used for motor or line protection.
