Relationship Between Meteorological Factors and Accidents of Traction Power Supply System of High-Speed Railway

Cheng, Hongbo / He, Zhengyou / Wang, Qi / Mu, Xiuqin

Some equipment of traction power supply system of high-speed railway is equipped outside, their state influenced by external environmental meteorological factors, and some occurred accidents of traction power supply system relate to meteorological factors closely. Time distribution feature of traction power supply system is proposed on the basis of statistics and arrangement of accident occurred nearly three years, and summer is the peak period of traction power supply system's failure; the relationship between accident and temperature, humidity, precipitation, wind speed, and lightning strikes is proposed, and their correlation has been analyzed. It is found that temperature, wind speed, and lightning are correlated with failure times significantly. Meteorological composite index is proposed to early warning the state of traction power supply system.
