摘要

电接触元件的传热性能是影响电能传输稳定性、可靠性的一个重要因素。基于多点接触电热耦合模型,建立了接触热阻的接触面传热新模型,利用ANSYS接触单元模拟接触电导生热和接触热阻生热现象,并考虑接触点随机性的存在对接触面温升有影响的因素,建立新的传热模型,并对新的模型进行了分析。
        The heat transfer performance of electrical contact elements was an important factor affecting the stability and reliability of power transmission. Based on multi-point contact thermal-electric couple model, a heat transfer model of contact surface thermal contact resistance was established. ANSYS contact element was used to simulate the heat generation of contact conductance and thermal contact resistance. The factors that influence the temperature rise of contact surface were considered due to the randomness of contact points, and a new heat transfer model was established and analyzed.
