GIS 局部放电在线监测超高频 Moore 分形天线研究
Research on UHF Moore fractal antenna for online GIS PD monitoring
摘要
Abstract
We designed a sensor of Moore fractal antenna for online monitoring partial discharge ( PD) in gas insula-ted substations ( GIS) , which is working at ultra-high frequency .Firstly, we analyzed the multi-frequency characteris-tics of this antenna in theory , used ANSYS HFSS to simulate the Moore fractal antenna and the Hilbert fractal antenna for comparison , and the results show that the Moore fractal antenna had great direction and omnidirectional radiation feature, then we made their physical ones according to the simulation results .The antennas were tested by vector net-work analyzer , and the results show that the Moore fractal antenna had more frequency bands when the VSWR<5 .Fi-nally, the partial discharge was tested in the laboratory , detected by Moore fractal antenna and Hilbert fractal anten-na.Compared the measurement results , the antenna proposed was quite promising for PD on-line detection applica-tions.关键词
