摘　　要：充分研究了现有的局放检测技术,分析了局部放电信号在电缆中的传输特性,以高频电流法为检测手段,采用无线或光纤作为传输媒介,提出分布式局部放电检测技术。通过现场实际应用,证明分布式局部放电检测技术在高压电缆交接试验时可以有效地检测出电缆中的微小绝缘缺陷。This paper fully studies the existing PD detection technology and analyzes transmission characteristics of partial discharge signals in the cable. Distributed partial discharge detection technology are proposed by using the high frequency current as the detection method and using wireless or optical fiber as the transmission medium. Through practical application of the field,the test results show that distributed partial discharge detection technology can effectively detect the tiny insulation defects in the cable.
