高压开关柜局部放电检测技术应用的相关探讨

局部放电问题在各类电力系统中较为常见,尤其是高压用电系统,其会造成一定的破坏作用,也会增加电能损耗。基于此,文章以局部放电现象以及其危害作为出发点,分析常见高压开关柜局部放电检测技术以及应用,重点介绍PDL1定位法和TEV检测法,并在文章最后给出实例检测内容,进一步明确相关理论。希望通过分析明晰局部放电检测技术,为后续工作提供必要的参考。

Partial discharge is a common problem in various power systems, especially in high-voltage power systems, which will cause some damage and increase the power loss. Based on this, the article takes partial discharge phenomenon and its harm as the starting point, analyzes the common high voltage switchgear partial discharge detection technology and its application, emphatically introduces the PDL1 localization method and the TEV detection method. At the end of the article, an example is given to further clarify the relevant theory. It is hoped that, by analyzing and clarifying the PD detection technology, it will provide the necessary reference for the follow-up work.
