接触网系统保护方式的探讨

Probe into the Protection Mode of the Contact Network System

介绍了电气化铁道接触网的保护机理,论述了回流线加避雷器、回流线加双重绝缘、回流线加闪络保护地线3种接触网保护方式的原理及优缺点,并从技术、经济方面进行了比较。

This paper introduces the protection mechanism of the contact network on the electrified railway,discusses on the principles and advantages/disadvantages of three kinds of the protection modes of the contact network system including the counterflow line ＋lightning arrester,the counterflow line＋ double insulation and the counterflow line ＋ flashover protectives ground wire,and compares them from technical and economic aspects.
