摘　　要：介绍了华中电网500 kV南昌变500 kV永南线线路高压电抗器B相高温过热故障,分析出铁心夹件和底脚之间的多点接触是造成故障的主要原因,提出了处理措施。处理后的高压电抗器运行状况良好。The analysis and treatment of high vohage reactor＇s high temperature overheat problem for 500 kV Nanchang Substation is presented in this paper. It was found that multi-spot contact between connection screw rod and bottom forms the galvanic circle is the main cause, and provided treatment measure. The high voltage reactor has worked well after treatment.
