摘要
针对电气化铁路运营带来的受电弓-接触网问题,仅从传统的动力学角度研究分析已显不足,受电弓滑板载流温度分布关系的深入研究是对其的有力补充。从热学角度出发,通过将流入受电弓电流基于等效电功率形式施加到受电弓滑板上,建立滑板接触点附近的温度分布模型;运用FLUKE热像仪测量同等受流条件下滑板接触点温度分布规律,验证了仿真方法的有效性,为弓网系统电-热耦合关系进一步研究提供参考。
It is not enough to use the traditional dynamic method to do the study and analysis of pantograph-catenary on electrified railway. Deep study of its current-temperature distribution can be mode as its complement. From dynamic perspective, the current is supplied from the pantograph to the slider with equivalent electric power mode. The model of the temperature distribution around the contact point is established, And then, the temperature distribution under the same condition is tested by using FLUKE imager. The simulation results are used to verify its effectiveness. A reference is given to researching on the electric-heat couple relationship of the pantograph-catenary.
