摘要(Abstract)：

通过一起局部放电在线监测系统报警的案例分析,对GIS局部放电监测系统中的干扰传播途径和抗干扰措施进行分析研究,确认报警信号由外界干扰引起,并采取了有效的抗干扰措施。对盆式绝缘子进行金属屏蔽接地后,使局部放电在线监测信号明显减小。
Through case analysis on alarming of online partial discharge(PD) monitoring system, this paper analyzes and investigates interference transmission path in PD monitoring system of GIS and the anti-interference measures. It is confirmed that the alarming signal is from external interference and effective anti-interference measures are taken. By metal screen grounding of basin-type insulator, signal of online PD monitoring is evidently reduced.
