一起220kV光伏电站光伏箱变故障分析和处理

Analysis and Treatment of Some Photovoltaic Box Transformer Accident in 220kV Photovoltaic Power Station

国家一直以来大力推广光伏电站的建设,随着“碳中和”“碳达峰”要求的提出,光伏电站建设达到空前高度。对一起220kV光伏电站光伏箱变突发跳闸事故进行了分析,通过外观检查、直阻测试、带电距离校对等最终确定故障点位置,并分析了故障原因,为以后的工程提供帮助和借鉴。

The country has been vigorously promoting the construction of photovoltaic power stations.With the requirements of"Carbon Neutrality"and"Carbon Peaking",the construction of photovoltaic power stations has reached an unprecedented height.A sudden trip accident of photovoltaic box transformer in 220 k V photovoltaic power station was analyzed.The location of the fault point was finally determined through visual inspection,direct resistance test,live distance calibration and the cause of the fault was analyzed,providing help and reference for future projects.
