高速铁路牵引供电系统避雷器预防性试验方法研究

在牵引供电系统中,避雷器作为保护牵引供电系统免受过电压侵害的重要设备,应用非常普遍,其本身的电气性能对于牵引供电系统可靠运行非常重要,避雷器带病运行将对整个系统安全构成严重威胁。本文对某高速铁路牵引供电系统中不同部位避雷器的电气结构进行分析,以期在最小环境干扰和最少拆解工作的条件下严格执行预防性试验规程,并从运行维护和试验角度提出合理化建议,为其他电气设备的预防性试验方法提供参考。

In the traction power supply system,lightning arrester,as an important device to protect the traction power supply system from overvoltage,is widely used.Its electrical performance is crucial for the reliable operation of the traction power supply system,and the operation of lightning arrester with faults will pose a serious threat to the safety of the entire system.The electrical structure of lightning arresters in different parts of traction power supply system of a high-speed railway are analyzed so as for the strict implementation of preventive testing procedures with minimal environmental interference and disassembly work.Reasonable suggestions are put forward from the perspectives of operation,maintenance,and testing.These will be able to provide reference for preventive testing methods of other electrical equipment.
