摘要

凝露是导致高压开关柜绝缘故障的主要原因之一。为了根据凝露形态分析开关柜是否安全运行，提出了一种弱光情况下基于凝露实时视频提取凝露大小、数量、面积占比等形貌参数的方法，并分析凝露形貌特征对沿面放电的影响。首先，人工搭建凝露模拟试验平台研究凝露的发展和形貌特征；其次，对不同时间段的凝露试验样品进行沿面放电试验；最后，结合凝露特征和沿面放电试验数据，分析凝露的形貌特征和沿面放电的相关性。结果表明：在高湿度环境下，沿面放电电压迅速降低，尤其是在凝露初期；随着凝露面积的增大和数量的减少，特别是在中后期，大面积水膜的形成会导致绝缘表面的湿区占比增加，液滴平均接触面积的增大，环氧树脂表面的导电性增加，从而导致闪络电压进一步降低，可为基于视频监测的开关柜的凝露闪络评估提供参考。

Abstract

Condensation is one of the main causes of insulation faults in high-voltage switchgear. To analyze whether the switchgear can operate safely based on the morphology of condensation

a method is proposed to extract morphological parameters such as the size

number

and area ratio of condensation in real-time videos under low light conditions

and to analyze the impact of these morphological characteristics of condensation on surface discharge. First

an artificial condensation simulation test platform is built to study the development and morphological characteristics of condensation. Next

surface discharge tests are conducted on condensation test samples at different time periods. Finally

combining condensation characteristics with surface discharge test data

the correlation between condensation morphological characteristics and surface discharge is analyzed. The results show that in a high humidity environment

the surface discharge voltage decreases rapidly

especially in the early stages of condensation. As the condensation area increases and the number of droplets decreases

particularly in the middle and late stages

the formation of large-area water films leads to an increase in the proportion of wet areas on the insulation surface

an increase in the average contact area of the droplets

and an increase in the conductivity of the epoxy resin surface

thereby further reducing the flashover voltage. This can provide a reference for condensation flashover assessment of switchgear based on video monitoring.
