110kV祁连变35kV开关计量CT异常分析

Analysis on the Abnormality of the Metering CT on 35 kV Switch in Qilian Substation

敞开式电流互感器由于制造原因导致运行中发生放电异音,影响设备稳定运行,通过对祁连110 kV变电站35 kV祁宝线55号开关A相计量CT运行中放电检查、分析和处理,消除了异音,确保了计量CT正常运行。

Because of defects in manufacturing,abnormal sound is detected from discharge of the metering open-type CT on a 35 kV switch in the Qilian substation. This paper introduces check works on the causes result in the discharging of the metering CT,analysis result and final treatment.
