摘　　要：针对发电厂厂用电系统的特点,分析了以往常用的几种中性点接地方式所存在的问题,提出了一种基于现代先进技术的新型接地方式———快速消X弧线圈接地加快速选线(跳闸),介绍了可实现该接地方式的产品———KD XH型智能化快速消弧系统和DDS型接地故障智能选线装置,并论述了该接地方式的优点和发展前景。In the light of the features of power station service systems, the problems existing in conventional neutral point treatments are analyzed. A state-of-the-art treatment, i.e. fast arc-suppression coil grounding plus rapid fault locating (tripping) is presented. The resultant products KD-XH intelligent fast arc-suppression system and DDS intelligent locater for ground faults are described along with the merits and potential of the proposed method.
