摘要
阐述了超高频(Ultra High Frequency,UHF)局放在线监测校核原理、测试校核试验设备及覆盖范围有效性校核、超高频局放在线监测现场校核、超高频局放在线监测校核异常及对策、案例分析。案例分析主要以220 kV大朗站GIS局部放电在线监测装置为例,检验局放在线监测装置是否能够有效发挥GIS局放在线监测与预警的作用。
This paper mainly describes Ultra High Frequency(UHF)partial discharge on-line monitoring and checking principle,the effective calibration of testing calibration equipment and coverage area,UHF partial discharge on-line monitoring for GIS equipment calibration field,UHF partial discharge on-line monitoring for GIS equipment anomaly checking and strategies and case analysis.The case analysis mainly takes the GIS partial discharge online monitoring device of 220 kV Dalang station as an example to test whether the local GIS partial discharge on-line monitoring device can effectively play the role of GIS partial discharge on-line monitoring and early warning.
