| 摘 要： | 电力电缆接头事故在电力电缆故障中占很大的比例，电力电缆接头的温度是反应其运行状态的重要参数。文中构建了电力电缆接头的简化结构模型，运用传热学的原理建立了电力电缆接头的温度场数学模型，应用有限元法分析了电力电缆接头的温度场分布。根据温度场的分布，把温度传感器合理地安装在接头的表面，可以通过电力电缆接头的结构特性、表面温度和环境温度，得到更加接近实际温度的接头线芯温度，能够及时准确地了解电力电缆接头的运行状况。

| Abstract: | There are many power cable junction faults in cable accidents, the temperature of the cable junction is very important and it can react to the cable junction running. This paper establishes a simplified power cable junction structure model, it uses the principle of heat transfer to establish power cable connector mathematical model of the temperature field, and applies Finite Element Method to calculate and simulate temperature field of cable junction. The temperature sensor is installed in the surface of t... |
