摘要
本文对同一建筑中TN与IT系统共存的问题进行了研究。对TN、IT系统的简单评述后,本文给出了基于电源转换开关、隔离变压器以及采用零序电抗器实现变压器中性点对接地隔离的三种解决方案。
This paper deals with the problem of compatibility of TN and IT system in the same structure. After a brief introduction to the TN and IT system, three methods are proposed based on transfer switch, insulating transformer and neutral - point earthing isolation using zero- sequence reactor.
