摘要：
The increase of train speed aggravates generation of the pantograph-catenary arc, which seriously affects the safe and stable operation of high-speed railway. In this paper, based on the classical arc models of Cassie and Mayr, the Cassie-Mayr series arc model was improved, considering the influence of arc length and train speed on the dissipated power in the transverse blowing arc. Through the experiment and comparison with the simulation results, the correctness of the improved model was validated. The actual parameter model of traction power supply system was established to analyze the effects of the separation time and the train speed on arc voltage and current. The U-I characteristic curves of pantograph-catenary arc at the trains speeds of 100 km/h and 400 km/h were compared. The results show that the voltage of pantograph-catenary arc increases with the increase of the separation time and the train speed. During arcing time of 0~100 ms, voltage amplitudes of sparking arc increase from 35 V to 137 V at the train speed of 100 km/h. As the train speed increases to 400 km/h, the amplitudes of sparking arc rise from 37 V to 386 V. © 2019, Department of Journal of the China Railway Society. All right reserved.
