Abstract

The joint of high-voltage cable is the weakest part in the whole cable system, and the local defect of the middle joint will affect the distribution of the internal electric field. This paper establishes a three-dimensional model by finite element simulation software based on the electric field calculation equation in Maxwell equation system. The influence of typical defects such as impurity, scratch and air bubble on the electric field distribution in the middle joint is analysed. The results show that the internal defects of the middle joint may cause distortion of the local electric field strength in the middle joint, which may lead to deterioration of the insulation.
