摘要

隔离开关是在有电压无负荷情况下分合线路用的开关设备。在2005年

中国率先在西北电网建设第1条750 kV线路

并且变电站的安装高度在海拔2 000 m左右。因此

研制适用于高海拔地区的800 kV高压交流隔离开关是高压电力领域的一个重要课题

具有重大工程应用作用。笔者在综述国外800 kV特高压交流隔离开关发展状况的基础上

通过对800 kV高压交流隔离开关的绝缘距离计算、均压环设计等一些技术参数进行探讨与研究

得出了一些初步的结论。根据西北的环境特点并进行线路统计耐受电压计算

确定高海拔地区的800 kV高压交流隔离开关的绝缘参数以及要研制800 kV高压交流隔离开关的结构参数

为研制800 kV高压交流隔离开关提供了技术保障。

Abstract

The disconnector is a circuit switching equipment used in no load condition.In 2005

China took the lead in the Northwest power grid construction

the first 750 kV line and substation installation height of about 2 000 m above sea level.Therefore

the development for high altitude areas of the 800 kV high-voltage AC disconnector is an important topic in high-voltage power field

have a significant role in engineering applications.This article based on reviews of the foreign 800 kV UHV disconnector development

and through the discussion and research of 800 kV high-voltage disconnector insulation distance calculation

grading ring design and some technical parameters

some preliminary conclusion are drawn.According to the environmental characteristics of the northwest area in China

study line statistical withstand voltage calculations to determine the high altitude of 800 kV high-voltage AC disconnector insulation parameters and to develop 800 kV high-voltage AC disconnector of structural parameters for the development of 800 kV high-voltage AC disconnect switch provides the technical support.
