Undervoltage compensation of pantograph catenary arc

Abstract

This paper describes the design of a new type of pantograph-catenary arc simulation test device and simulation of the arc generated by the pantograph during operation under laboratory conditions. The influence of the burning position of the pantograph-catenary arc on the overvoltage of the traction system is studied. Corresponding suppression measures for the arcs are proposed, and the dynamics of the arc processes are carried out by theoretical simulation. The characteristics of the pantograph-catenary arc and the discharge process are analyzed, and the relationship between the characteristics of the pantograph and the arc is explored.
