摘要

用EMTP程序对用不同的氧化锌避雷器限制GIS内快速暂态过电压的效果进行了计算

并给出了快速暂态过电压与暂态地电位升高的简单算式。同时对某GIS的隔离开关操作引起的暂态地电位升高数值进行了现场测量。提出了用氧化锌避雷器阀片限制GIS暂态地电位升高的措施。

Abstract

This paper uses EMTP program to calculate the effects of suppression on very fast transient overvoltages in GIS when employing different ZnO Surge Arresters

and gives a simple formula of transient grounding potential rises versus very fast transient overvoltages. A real GIS’s transient grounding potential rise caused by operation of disconnector was measured on site. Following the results

this paper proposes to suppress the GIS’s transient grounding potential rises by using ZnO element.
