摘要
Abstract
For studying numerical sizes of electric field distribution and defects of cable accessories when there are defects such as air gap and impurities of stress cone and cable insulation in insulation structure of cable accessories at the interface, this paper uses finite element method,takes 220 kV high voltage cable accessories as model,adopts ANSYS software to sim-ulate three-dimensional electric field distribution of the joint and compares with analysis result of symmetrical electric field distribution of the two-dimensional axis.For ensuring electric performance of the interface,it uses testing device made of the same material as cable accessories to conduct a test to confirm satisfaction for interface pressure of electric performance of cable accessories.关键词
