T型电缆接头温度场仿真分析OA

In this paper,the structure and classification of commonly used cable joints are summarized.On this basis,the typical T-shaped joints are selected for analysis and research,and the geometric shapes and dimensions of the main components of the joints are obtained by field measurement.Based on this,a model is established.According to the principle of heat transfer,the model of cable joint is established,and the distribution law of temperature field of cable joint under normal operation condition is calculated by finite element analysis,and its influence factors are analyzed.The effects of ambient temperature,air convection heat transfer coefficient and load current on the temperature field distribution of cable joints are obtained.The analysis results of the temperature field distribution characteristics and influencing factors of the cable joint obtained in this paper can provide a reference for the optimal design of the cable joint and the installation and layout of the temperature monitoring equipment.
