摘要
通过对电气设备保护接零系统的概述,在TN-C系统负载不对称时,通过对中性点电压的分析及中性线电流与相线电流的比较,讨论了该系统存在的问题以及应对措施,最后分析了在TN系统中应注意的几个问题。
This text summarizes the protective zero terminating system of the electric equipments.While the load of the TN-C system is dissymmetry,by analyzing the neutral point voltage and comparing the neutral line current with the phase line current,this paper discusses the problems exist in the system and the corresponding replying measures.Finally,it analyzes several problems that should be noticed in the TN system.
