高压配电柜绝缘受潮击穿原因分析及改造

Modification of Insulation for 35 kV High Voltage Switchgear

高压配电柜作为电力系统的重要组成部分,对于电力的正常稳定供应有着重要的意义。在实际运行过程中,高压配电柜会因其工作状态以及环境因素等影响,出现绝缘受潮击穿的现象,危害到电力的正常供应。本文以宁波市周公宅水库的35kV高压配电柜为实际例子,对其日常的工作状态进行总结,并分析了发生绝缘受潮击穿问题的原因。同时以此为基础,结合实际工作经验,对高压配电柜绝缘受潮击穿的处理方法进行了总结,并对处理后的结果进行了探讨。这些研究对高压配电柜的应用和电力系统的发展有着重要的意义,有很好的现实价值。

in modern production and life,power equipment plays an important role.As an important part of the power supply system,the high-voltage distribution cabinet plays an important role in the normal and stable power supply.In the actual work process,the high-voltage distribution cabinet will be due to its own working state and environmental factors,resulting in insulation damp breakdown phenomenon,endangering the normal supply of electricity.In this paper,we take the 35 kV high-voltage distribution cabinet of Zhougongzhai Reservoir in Ningbo City as an example,summarize its daily working state,and analyze the reason of insulation damp breakdown.At the same time,we summarize the treatment methods of insulation damp breakdown of high voltage distribution cabinet and discuss the results after treatment.These studies are of great significance to the application of high voltage distribution cabinet and the development of power system,and have very good practical value.
