摘要：
With the continuous increase of train speed,undulations of catenary and vibrations of the pantograph head result in generating pantograph- catenary arc frequently,intensifying the abrasion betw een pantograph strip and catenary w ire,w hich has seriously influenced the current collection and safety of electric multi units( EM U). It is necessary to study the pantographcatenary arc in immediately. Some researchers develop a few pantograph- catenary arc testing equipment,w hich couldn’t really reflect the operating condition of pantograph-catenary system. In this paper,the pantograph-catenary arc test apparatus w as developed,w hich simulated the flexible and straight contact of pantograph strip and catenary w ire,based on the coupling relationship betw een pantograph and catenary. The equipment w as used to research the electrical parameters of the pantograph-catenary arc and the dynamic contact resistance.
