摘　　要：针对电气接头温升问题,本文构建了接头热电耦合数学模型,提出有限元模型进行计算,以提升计算精准度和速度,并基于模型进行温升试验。结果表明,接触电阻、电流强度、接头宽度和厚度均会对接头温升造成影响。In response to the problem of temperature rise in electrical connectors,this paper constructs a mathematical model for thermoelectric coupling of connectors and proposes a finite element model for calculation to improve calculation accuracy and speed.Based on the model,temperature rise tests were conducted,and the results showed that contact resistance,current intensity,joint width,and thickness all had an impact on the temperature rise of the joint.
