| 摘 要： | 110 kV避雷线发热非常罕见.笔者对接入平果牵引站的110 kV马平牵线的避雷线发热情况进行了现场调查和分析,得出避雷线发热与牵引站部分回流线被盗、地回流电流过大有关.同时利用CDEGS软件建立了仿真模型进行了计算,仿真结果显示,当牵引负荷较大时,避雷线中有较大牵引电流流过.在牵引站进行的现场测试验证了分析的正确性....

| Abstract: | Field survey and analysis were performed about a lightning wire heating fault of 110 kV Maping traction line into Pingguo traction substation.It was found that the heating was generated by exceeding ground reflux current due to the missing of a length of reflux line.Simulation of the traction substation by the software CDEGS shows that greater traction current appears in lightning wire when traction load is larger.A test in the traction substation verifies the correctness of the analysis.In addition,some su... |
