Abstract

In the power system, there are a large number of cable joints in the electrical transmission equipment. There are about one cable joint every 100 meters in the long-distance cable. A large number of cable joints are easy to cause internal and external faults. The fire caused by the problem of cable joints accounts for more than half of the total cable accidents. It is also a good choice to use insulation material between the cable and the environment, and to inject high insulation and good heat conduction material between the measuring point and the joint. This situation is mainly suitable for cable components with small heat capacity. For electrical equipment in normal operation, the greater the temperature difference between inside and outside the cable, the greater the resistance at the joint. It can be understood that the warning signal of cable joint failure can be replaced by the temperature of the cable.
