摘要
Abstract
The case that built-in type UHF sensor alarmed after 1 100 kV GIS circuit breaker switching is presented. The fault is located successfully based on the propagation characteristics and pattern recognition techniques of UHF signals, and then attenuation rule of UHF signals in different gas chambers is concluded. By tracking and analyzing the UHF signal amplitude and on-line frequency spectrogram information and de-tecting discharge point by faulty gas chamber disassembly, the above-mentioned diagnosis and analysis is proved correct, providing an effective example for application of UHF-based method in UHV GIS projects. In the final, the paper brings forward some suggestions on field detection of UHF-based method.关键词
