摘要：
The temperature rise of pantograph strip in electric contact system between pantograph and catenary will change the environment of contact surface, aggravate friction and wear and finally affect the reliable operation of electric locomotives. In this paper, the effects of joule heat, friction heat and arcing heat on the temperature rise characteristics of pantograph strip were studied respectively based on a home-made test apparatus for electric contact between pantograph and catenary. The characteristics of these three heat sources and their impacts on the temperature rise of pantograph strip were analyzed in accordance with the theory of heat transfer. The temperature distributions in the strip and its variations were recorded by a thermal infrared imager. The research shows that joule heat plays a dominant role in the temperature rise while the impact of friction heat on the amplitude of temperature rise is minor. Arcing heat has a local heating effect on the strip. The temperature rise of the contact point between pantograph and catenary under the joint effects of 3 heat sources is smaller than that under joule heat only, which could be an evidence indicating that the contact wire takes away heat through friction with the strip, which has certain cooling function for the strip. The research makes sense for the theory of temperature rise in electric contact system between pantograph and catenary. © 2019, Department of Journal of the China Railway Society. All right reserved.
