摘要

中国相关规程标准中尚未对±200 kV电压等级直流换流站设备不停电时的安全距离做出说明

如果按照高一档电压等级±500 kV安全距离来选取±200 kV电压等级的安全距离

存在安全裕度明显偏大的现象。通过对±200 kV换流站5种典型电极对其它设施（接地）间隙进行正极性标准操作冲击试验

借鉴带电作业相关研究成果

计算得到±200 kV换流站内典型电极的最小安全距离和危险率

同时结合人体在换流站内的活动范围

确定了±200 kV换流站典型不同的设备不停电时的最小安全距离为2.8 m。研究结果可为±200 kV换流站设备不停电时的安全距离的最终确定提供技术参考。

Abstract

The existing Chinese specifications and standard do not include the safe distance of ±200 kV voltage class converter station equipment with power.If select a safe distance for ±200 kV voltage class according to that for as high as ±500 kV voltage class

the safety margin is too large.In this article

normal polarity standard operation impact test was conducted for the gaps between five typical electrodes and the other facilities（grounded）in ±200 kV converter station

so the resulting minimum safety distance and risk rate of the typical electrode in the±200 kV converter station were calculated with reference of the related research on live operation.Moreover

considering the range of human activity in the converter station

the minimum safe distance to different typical equipment with power in the ±200 kV converter station was determined as 2.8 m.This research may provide a reference for determination of safe distance to the equipment with power in ±200 kV converter station.
