摘要

电晕是变电站内十分普遍的一种放电现象

也是高压设备可能存在缺陷或故障的征兆信号。采用"日盲"型紫外成像仪在不同的气象环境下对多座500 kV变电站进行了现场检测

发现了部分设备的电晕放电现象。对上述放电现象进行了分类

并对放电原因进行了分析

结合实验室的研究和现场测试

提出了结合设备的放电位置、放电强弱、放电形态、放电机理并结合气象因素进行放电评估的综合分析方法

实际应用证明了该方法的有效性。

Abstract

Several 500 kV electric substations are detected with a "solar blind" type UV imager under different weather conditions

and corona discharges are found in some equipments.The discharge phenomena are classified

and the causes of discharge are analyzed.Combining laboratory research and on-site tests

a comprehensive estimation method of corona discharge is proposed

in which discharge location

discharge strength

discharge pattern

discharge mechanism and meteorological factors are taken into account.Practical application proves the effectiveness of this method.
