摘要
基于电场有限元数值计算和界面沿面放电试验研究结果,研制了优化绝缘结构设计的插拔式快速终端和接头,其应力锥的绝缘材料采用三元乙丙橡胶,外屏蔽为不锈钢。,终端和中间接头插拔配合的过盈值、复合界面压强值的理论计算值和按IEC、GB、Q/WLT等标准进行型式和补充试验的结果基本一致,寿命可达1000次。
Design of termination and joint for pass-by cable used to living-work had been optimized based on FEM analysis and study results of surface discharge experiments in this paper. According to IEC 60502 standard, type test and complementary tests including inserted in and drawn out 1000 times fatigue test for validating their electrical characteristics are discussed in the paper. The research results prove that power cable with rated voltage up to 35 kV may be connected and/or branched on-site quickly and safely using these terminations and joints.
