摘要
影响铁路信号继电器触点接触电阻变化的因素很多,各个因素之间又相互关联,相互影响。对接触电阻的概念进行详细阐述,重点分析影响铁路信号继电器触点接触电阻变化的因素以及各因素之间的关系。
There are many factors affecting the contact resistance of railway signal relay,and the factors have connections and influences with each other.This paper elaborates the concept of contact resistance in detail,and focusing the analysis on the factors affecting the change of contact resistance of railway signal relay and the relationship between the factors.
