摘要

针对电缆接头线芯的温度无法直接测量的问题,应用有限元法建立了电缆接头稳态温度场分布模型；利用ANSYS软件对其温度场分布进行了仿真分析,得到了电缆接头线芯温度和表面温度的关系；根据仿真结果,提出了一种基于温度场的电缆接头温度监测系统的设计方案,给出了系统中供电电源和数据处理的设计,为工程中监测电缆接头温度、电缆运行状况提供了理论依据.%In view of problem that core temperature of cable joint cannot be measured directly,the paper applied finite element method to establish a model of steady temperature field distribution of cable joint,used ANSYS software to simulate and analyze the temperature field distribution,obtained the relationship between the core temperature and surface temperature of the cable joint.It proposed a design scheme of temperature monitoring system for cable joint based on temperature field according to simulation result,gave design of power supply and data processing of the system,so as to provide a theoretical basis for monitoring of joint temperature and running status of cable in engineering.
