摘要(Abstract)：

为验证110 kV高压电缆振荡波局部放电试验技术检测电缆绝缘潜在性缺陷的有效性,以及积累该项试验技术现场应用经验,在高压大厅进行了110 kV电缆终端及中间接头放电仿真模型局部放电振荡波模拟试验,并进行该项技术对试验电缆破坏性的比对研究。试验表明高压电缆振荡波局部放电试验技术可检测并定位电缆终端较明显的局部放电缺陷,但对于半导电尖端较小的模拟缺陷,则无法检测到局部放电。
To verify the validity of 110 kV high voltage cable oscillation partial discharge test for latent cable insulation defect detection as well as experience accumulation of test technology in field application, partial discharge oscillation wave simulation test on 110 kV high voltage cable terminations and middle joints discharge simulation model is performed in the high voltage test hall, and comparative research on cable damage by use of the technology is conducted. The test shows that partial discharge test technology of high voltage cable oscillation wave can effectively detect and locate clear partial discharge defects of cable terminations and middle joints; however, it can not detect partial discharge from semiconductive terminal with small analog defects.
