Abstract
With the acceleration of urbanization, the use of power cables is increasing. However, unlike overhead lines, power cables are laid in underground pipe galleries. It is difficult for power grid operation and maintenance personnel to carry out patrol inspection of power cable lines through intuitive detection means. Therefore, many defects of power cables are difficult to be found in time. During the operation of power cables, the influence of insulation electrical treeing is very large. Electrical treeing is an irreversible insulation damage. Electrical treeing can easily lead to penetrating discharge channels in cable insulation, thus affecting the reliability of the entire transmission system. In response to the above problems, the project team carried out an experimental study on the influence of the defect characteristics of XLPE insulated cables on the initial voltage of electrical tree. Based on the experimental results, this paper deeply analyzes the influence mechanism of cable defect characteristics on electrical tree. The numerical model of cable defects is constructed, and the influence of various factors on the generation of electrical tree is analyzed. Finally, the technical measures to weaken the deterioration of electrical tree in cable insulation are put forward. This research work has guiding significance for optimizing the performance and quality of power cables and improving the operation level of cables.
