Simulation Analysis of Pantograph-Catenary Arc Based on Improved Mayr Model
摘要
Abstract
Pantograph-catenary arc is likely to burn pantograph strip and contact wire, which seriously endangers the safe operation of the train.This paper introduces the Mayr arc model and analyzes the energy process of the pantograph-catenary arc column based on the theory of energy balance and the theory of transverse blowing arc,and the effect of the high speed airflow on the arc dissipation power is studied. The relationship between the arc dissipation power Ploss,the train speed ν,the current I and the off-line spacing l is defined and Mayr arc model is improved. Then, the improved Mayr arc model is built with Simulink simulation software. Finally, the simulation waveforms and experimental waveforms are compared and analyzed, and the rationality of the arc model is verified. The results show that with the increase of the train speed the effect of the airflow on the arc is getting more significant; the power consumption of the arc, the peak arcing voltage and the peak arc extinction voltage increase.关键词
