摘要
针对交流低压配电系统中性点接地方式而产生不同的配电制式,按照DL/T621-1997《交流电气装置的接地》给出的TN-S、TN-C、TN-C-S、TT、IT五种交流低压配电制式,逐一分析了特性,探讨其应用。
Different distribution systems appear due to different neutral point grounding mode in AC low voltage distribution system, one by one the characteristics of five kinds of AC low voltage distribution systems were analyzed, TN - S, TN - C, TN - C - S,TT,IT specified in DL/T 621 - 1997 Code of AC Electric Devices Grounding＂ and their application was discussed.
