Abstract:With the rapid development of rail transit industry in China,along with the continuous increase of traffic pressure on urban pavement and the improvement of urban traffic informatization level,it still maintains a rapid development trend. As the core component of vehicle operation,traction converter mainly undertakes the function of energy conversion and transmission. Its performance will directly affect the operation of vehicles and the ride environment in the vehicle. Starting from the converter equipment of rail transit vehicles,this paper introduces the protective design of the box,and explains several key designs for how to improve the protective performance of the converter box.
