Abstract

Abstract:

The catenary and pantograph system is one of the key systems connecting the traction power supply circuit.The normal operation of the bow-lift control loop is of great significance to the stable transmission of the catenary and pantograph.This paper aims at the pathological fluctuation of solenoid valve voltage,current and other parameters in the abnormal state of pantograph,and uses it as the core parameter of the bow control loop to build a test platform for pantograph control loop.The solenoid valve voltage,current and gas pressure at the outlet of the pantograph valve plate were experimentally studied.By studying the changing rules of various parameters under different operating conditions,the paper explores the essential causes of parameter fluctuations,and analyzes and evaluates the contact status of the bow net under different operating conditions.

Key words: catenary and pantograph, pantograph test, electromagnetic valve, valve plate pressure
