摘要
为了研究10 k V XLPE电缆本体受伤电场情况,防止电缆缺陷局部放电电场发展导致电缆接头击穿,通过分析XLPE电缆主要缺陷类型及原因来确定引起电缆故障的主要类型故障,然后利用有限元分析方法对电缆本体受伤情况电场进行仿真研究,最后根据仿真结果得出结论:在电缆本体空洞插入铁丝会造成电场畸变,严重时会造成绝缘击穿,为今后电缆线路故障分析提供参考。
In order to study the electric field when there are defects in 10 kV XLPE cable and prevent the electric field devel-opment of partial discharge caused by cable defects leading to cable connector breakdown , the main defect types and reasons of XLPE cable are analyzed to determine the main types of cable fault .And then ANSYS is used to study and simulate the elec-tric field of cable body defect .Finally, based on the simulation results it is concluded that inserting the iron wire into the cable can cause the electric field distortion and seriouly it can cause insulation breakdown , which can provide a reference for the fu-ture study of cable line fault .
