Abstract

Abstract: In order to improve professional management of traction power supply and ensure operational safety of traction power supply system, database was established based onkey items like time, location, impact, cause and responsibility of traction power supply accidents by using statistical analysis methodand considering characteristics of traction power supply. Then qualitative analysis was carried out from different dimensions,trend and law of accidents were summarized,main factors affecting system's operational safety were found and suggestions proposed.The results show that accidents have been declining in recent years. The system's operation safetyis greatly affected byexternal environment. Accidents caused by overturning rod, breaking line and collapse of catenary are more frequent and have a greater impact.

Key words: traction power supply, operation safety, accident statistics, qualitative analysis, influencing factors
