Analysis on cause and effect of overhead contact wire arcing in transit
Wu Wei;Ma Junjie;Lan Zhikun;
By analyzing the contact resistance and pressure, current and speed under the interaction between the overhead contact wire and pantograph system, this paper summarizes the sliding electrical contact characteristics of pantograph and contact wire system. Based on the electric arc theory and practical operation tests, it analyzes the causes of the contact wire arc phenomenon and summarizes their influence. Suggestions are also made for the arcing phenomenon in urban rail transit overhead contact system.
