摘要

±1100 kV换流站阀厅空气净距的研究已经成为特高压直流输电工程设计中的关键问题之一

空气净距的决定因素是放电电压和海拔高度

g参数修正法综合考虑了大气压力、温度、湿度等因素的影响

对实际海拔下放电电压进行修正。文中基于g参数迭代法进行特高压直流阀厅金具空气安全净距的计算

并将该方法运用到准东换流站阀厅的空气净距设计中

给出阀厅内主要设备金具的空气净距值。为特高压换流站阀厅的建设提供了一定的依据。

Abstract

The research on calculation of air clearance in fittings of valve hall of ±1 100 kV converter station is one of the key issues in the UHVDC engineering design. The air clearance is determined by discharge voltage and altitude

the g parameter correction method takes into account the effects of atmospheric pressure

temperature and humidity

and corrects the discharge voltage at the actual altitude. This article calculates the air safety clearance in fittings of UHVDC valve hall based on parameter g iteration method. The method is applied in the air safety clearance design for Zhundong converter station valve hall

it gives the air safety clearance value of the main equipment. It provides a certain basis for the construction of UHV converter station valve hall.
