摘要

西北地区在建和投运的750kV输电线路多处于高海拔地区

其电晕损失现象较为明显。笔者以6×LGJ-400/50型导线为例

借助可移动电晕笼

在环境气候试验室中测量其大雨条件下、0～4000m海拔范围内电晕损失随海拔的变化关系

参考标准并利用最小二乘准则对测量数据进行拟合

提出两种不同形式的电晕损失海拔修正公式。

Abstract

In the northwest region of China

most of the 750 kV transmission lines in use or under construction are located in high altitude areas

leading to obvious corona loss. This paper takes the six-bundle conductor 6×LGJ-400/50 as an example to measure its corona loss by using the corona cage in an environmental climate laboratory with heavy rain condition

and the relation between corona loss and altitude within 0～4 000 m is achieved. Then reference standard and least-square method are employed to fit the measured data. Consequently

two different altitude correction formulas for corona loss are suggested.
