为了获得特高压交流同塔双回输电线路雨天电晕损失评估的关键数据,采用特高压交流同塔双回试验线段、特高压电晕笼两种试验手段,应用光纤数字化测量方法监测雨天气象条件下特高压交流同塔双回试验线段电晕损失,测量特高压电晕笼人工淋雨降雨率为12、16、20 mm/h条件下8×LGJ-630分裂导线电晕损失。并采用有效电晕损失等效计算方法,对电晕笼与试验线段试验结果进行等效计算分析。电晕笼与试验线段电晕损失基本等效,其误差在±6.5%范围内。研究结果验证了电晕笼分裂导线电晕损失试验结果与特高压交流同塔双回试验线段雨天监测结果的一致性,同时证明了有效电晕损失等效计算方法可以较为准确地将淋雨条件下电晕笼分裂导线电晕损失等效换算成特高压交流线路,研究成果可为特高压交流同塔双回输电线路电晕损失评估提供参考。

In order to obtain key data of corona loss of UHV AC double circuits transmission line under rain,two methods,namely,double circuits test line and UHV corona cage,were adopted,moreover,the optical fiber data measurement method was applied to monitor rainy corona loss of UHV AC double circuits test line in UHV corona cage,and 8×LGJ-630 bundle conductors＇ corona loss was measured under artificial rainfall rates of 12mm/h,16mm/h,and 20mm/h.Then the reduced corona loss equivalent calculation method was used based on the test results of corona cage and test line.The corona loss results of corona cage and test line were basically equivalent,and corona loss equivalent error was controlled in ±6.5% range.The research results verify that,the test results of bundle conductors＇ corona loss in corona cage are consistent with monitoring rainy corona loss of UHV AC double circuits test line,and the reduced corona loss equivalent calculation method is an effective way to convert bundle conductors＇ rainy corona loss in corona cage into the one of UHV AC line.The research results can provide a reference for UHV AC double circuits transmission line＇s corona loss evaluation.
