摘　　要：用超高频法模拟研究了油 /纸绝缘中局部放电并用内置超高频探头实现了电力变压器局部放电的在线检测。该法有望解决变压器局部放电在线检测中的抗干扰问题。The partial discharge (PD) pheromena in transformer oil/paper insulator were investigated experimentally with ultra-high frequency (UHF) partial discharge detect technique in this paper. In site a UHF sensor was installed in the power transformer in which there were defets probably. PD in the transformer could be detected on-line by UHF technique. It is hopeful that problem of anti-interfere in transformer on-line PD detect could be settled with UHF partial discharge detect technique.
