高压开关柜局部放电检测技术的研究

Research on Detecting Technology of Partial Discharge in HV Switchgear

高压开关柜是电力系统中非常重要的电气设备,其内部发生的局部放电会对开关柜乃至整个系统造成严重危害。文中介绍了适用于高压开关柜内的局部放电检测技术,并提出了基于这种技术的故障分析和判断方法,有助于及时有效地发现故障隐患,保障高压开关柜的安全运行。

Partial discharge in high voltage switchgear can result in catastrophic failure of the switchgear and in some cases of the whole substation. This paper introduces a technology to detect partial discharge in HV switchgear, and propo- ses methods of analyzing and judging failure based on the technology, which will help discover potential faults timely and effectively and thus guarantee safe operation of HV switchgear.
