Abstract

Since the thermal expansion coefficient of the insulating material and the metallic material in the cable joint different is large, when the temperature changes, there is great stress in the insulating material or the tightening of the insulating material and the metal material, causing damage to the insulation, and the temperature too high will damage the thermal stability of the material, resulting in insulation damage, seriously affecting the safe operation of high-speed trains. In order to improve the reliability of power supply, finite element method is used to analyze the distribution characteristics of temperature field and stress field of cable joint in the process of normal and insulated aging. The study shows that the insulation state of cable joint can be judged by detecting the surface temperature and strain of cable joint, and it can provide a reference for the maintenance and maintenance of the cable head.
