摘要
针对铁路牵引供电系统二次回路防雷问题进行研究和分析,提出在所用变压器、交直流电源回路、UPS电源回路、弱电回路等应采取分级防护方案以防过电压。
Study and analysis are made with respect of the problems of the secondary equipment lightning protection for the railway traction power supply system,the paper puts forward the graded protection plan for the auxiliary transformer circuit,AC or DC power circuit,UPS circuit and low voltage circuit so as to prevent the overvoltage.
