750 kV高压电抗器套管将军帽发热分析及处理

Analysis and Treatment of Overheating Defect of 750 kV High Voltage Reactor Bushing Coupler

针对某750 kV变电站高压电抗器套管发热缺陷,查找具体发热部位,分析并明确了发热原因为套管将军帽与导电杆连接部位接触不良。对将军帽进行处理后重新安装,有效消除了套管发热缺陷,并针对此类缺陷提出了相应的整改措施。

In allusion to the overheating defect of a high voltage reactor bushing in a 750 kV substation,the overheating position is found,and the cause of overheating is analyzed and determined,which is the poor contact between the bushing coupler and the conductive rod.After the coupler is treated and reinstalled,the overheating defect of the bushing is effectively eliminated,and the rectification measures are proposed for such defects.
