20kV系统客户端变电所设计探讨

Discussion about 20 kV System Client Substation Design

分析了20 kV电压等级相对10 kV电压等级的优越性,介绍了20 kV电压等级配电中性点接地方式的不同,并阐述了20 kV电压等级在设备选型、变配电室布置、10(20)kV过渡、接地电阻等方面需要注意的问题,以为同类设计提供参考。

This paper analyzed the superiority of 20 kV voltage class relative to 10 kV voltage level. The differences of neutral point grounding way of 20 kV voltage grade were introduced, and the problems need to be paid attention to for 20 kV voltage class were expounded,including equipment selection, substation chamber and transformer room layout, 10（20）kV transition, grounding resistance, etc. It could provide reference for similar design.
