摘要
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 suggestions are offered to ensure safe operation of the traction substation.关键词
