摘要
通过分析中性点非直接接地系统易发生单相接地故障,发生单相故障时电压变化对过电压保护器的影响,为解决带间隙组合式过电压保护存在的问题,提出了新型的六柱全相双安全保护装置。
In the article, it is analyzed the effects of voltage change on overvoltage protector when there is single - phase fault for neutral point of non - solid earthed system. In order to solve the existing problems of combined overvohage protector with clearance, the new six - column all - phase double safety protector is developed.
