摘要
分析了配电网采用的中性点接地方式,对中性点经小电阻接地和小电流接地各种不同的中性点接地方式作了比较。针对35kV,10kV不接地系统易出现弧光接地过电压以及老式消弧线圈的固定分级调档满足不了系统频繁变化时随时调谐需要的缺点,提出采用自动跟踪补偿消弧装置的方法,并结合本地区的实际经验,阐述了自动跟踪消弧线圈的工作原理、优越性及运行中存在的问题。
The neutral point grounding adopted in distribution network is analyzed in this paper and the different ways of neutral point grounding are compared such as grounding via small resistance and grounding via small current.With regard to the disadvantages of grounding arc over-voltage often happened in the non-grounding 35kV/10kV systems and the incapability of satisfying the frequent variatio of the systems by traditional arc-decreasing wires because of their fixed stages,method of using automatic following-up compensation arc-decreasing wires is introduced and its working principle ,advantages and some problems encountered in its application are discussed in the background of local application experience.
