Research on the Heat Transfer of High-Speed Railway Pantographs

Abstract:

In the pantograph-catenary system of electric railroads, there is friction heat between high-speed moving pantograph sliders and the contact wires, leading to a temperature increase on the contact surface. On the contact surface under the current collecting conditions, there are also contact resistance heat and arc heat produced by the current effect, leading to further temperature increase of the pantograph sliders. This paper applies finite element method to analyze the steady heat transfer and transient heat transfer of the pantograph sliders of high-speed train and studies the transient heat transfer of sliders and contact wires in actual movement. The computing results determined the temperature fluctuation range and temperature distribution when sliders and contact wires are in normal working condition.
