摘要
500 kV平果变电站P2B号主变压器的油色谱试验结果显示,中压侧B相套管的乙烷含量超标。通过分析该套管历年的试验数据及红外巡检情况,根据相关国标及行标判断该套管存在中温过热现象,建议立即更换。
Test results of oil chromatogram of No.2 PB transformer in 500kV Pingguo substation show that the content of ethane of phase B bushing on the medium voltage side is over limit. According to the analysis of test data of the bushing and infrared detection result, and based on national and industry standard, it is judged that the bushing has overheat phenomenon at medium temperature. It is suggested that the bushing be replaced.
