Abstract
Medium voltage cables are widely used in various distribution networks. The cable joint are prone to discharge defects during installation and operation to destroy their insulation structure. In order to study the impact of different defects on the electric field strength of the cable joint, this paper established a 26/35 kV XLPE in SolidWorks. The three-dimensional physical model of the cable body and the cable joint is designed with four typical defects models of air gap, cut, impurity and scratch. These typical defects was simulated by finite element method (FEM) in the three-dimensional electric field simulation of CST STUDIO and through comparison to get the influence of defects on the electric field strength. The results show that these four kinds of defects will increase the electric field strength of the cable joint and even lead to a huge failure caused by insulation breakdown. It provides an important reference for diagnosis of the insulation condition monitoring of the cable joint in the future. Ensure the safety and reliability of power system operation.
