新疆高温差地区750kV电抗器用金属波纹式储油柜选型及T/H曲线矫正计算

T/H Curve Correction Calculation and Type Selection of Metal Corrugated Oil Conservator for 750kV Reactor in Xinjiang High Temperature Difference Area

在介绍750kV金属波纹管内油式储油柜结构和原理的基础上,分析了新疆地区某750kV变电站高压并联电抗器所使用的金属波纹式储油柜在高温差环境下油位变化规律和加补充油工作存在的问题,论证了储油柜选型的正确性,矫正了储油柜油位温度曲线,并提出了运行维护建议。

Based on the principle and structure of 750kV metal corrugated oil conservator, the problems of supplementary oil and the law of the oil level change of the metal corrugated oil conservator for 750kV reactor in Xinjiang high temperature difference area are analysed. The correctness of the type selection of oil conservator is demonstrated. The oil level and temperature curve is corrected. The operation and maintenance suggestions are put forward.
