摘要

电力电缆由电缆本体和电缆接头组成，电缆接头内部的温升是影响电力电缆线路载流能力的关键因素。针对电缆接头材料参数分散性大和热流扩散规律不明显等问题，文中提出了一种基于主热流分析的电缆接头热点温度反演辨识方法，以准确辨识接头内部的热点温度。首先建立了10 kV三芯电缆及接头的有限元仿真计算模型，得到温度场分布规律。其次通过分析电缆接头的热流扩散规律，建立了电缆本体的热路模型，并采用正交试验法设计训练样本和测试样本，确定了距离接头端部0.1、2.0 m的2个导体特征温度点，从而构建了本体径向反演和导体轴向反演的接头热点温度组合反演方法。最后搭建了电缆多工况温升试验平台，在不同负载、外界风速和环境温度下，试验结果表明热点温度仿真值与试验值最大误差为2.29 K，热点温度反演值与试验值最大误差为3.92 K，为电缆接头热故障监测方法提供了参考。

Abstract

Power cables are composed of the cable body and cable joints

and the temperature rise inside the cable joints is a key factor affecting the current carrying capacity of power cable lines. In view of such issues as large dispersion of cable joint material parameters and unclear heat flow diffusion

in this paper a cable joint hot spot temperature inversion identification method based on main heat flow analysis is proposed to accurately identify the hot spot temperature inside the joint. Firstly

a finite element simulation calculation model for 10 kV three core cables and joints is set up to obtain the temperature field distribution. Then

a thermal path model of the cable body is set up by analyzing the heat flow diffusion law of cable joints. The orthogonal test method is used to design training and testing samples and determine two conductor characteristic temperature points at distances of 0.1 m and 2.0 m from the end of the joint

thus

a joint hot spot temperature combination inversion method for radial and axial inversion of the body is constructed. Finally

a multi condition temperature rise test platform for cables is set up. The test results shows that under different loads

external wind speeds and ambient temperatures the maximum difference between the simulated and experimental values of the hot spot temperature is 2.29 K

and the maximum error between the inversion value of the hot spot temperature and the experimental value is 3.92 K

which provide a reference for the thermal fault monitor ing method of cable joint.
