An LS Peano fractal antenna, which integrates the self-similarity and spatial filling features of fractal technology, was designed for detecting the ultra-high frequency (UHF) signals generated by gas-insulated switchgear (GIS) partial discharge (PD). Firstly, we used ANSYS HFSS to simulate and design the LS Peano fractal antenna. Then we made the antenna object according to the optimised simulation results. Finally, PD trials involving a metal protrusion defect are conducted therewith. The test results show that: the LS Peano fractal antenna has ellipsoidal directivity; the measured results indicate that the voltage standing wave ratio (VSWR) of this antenna is less than 4.5 in the range from 300 MHz to 3 GHz, which has better PD monitoring ability; the VSWR of this antenna is less than 2 in the range from 1.1 GHz MHz to 3 GHz, which has a higher density of monitoring PD.

用于局部放电 GIS 检测的 UHF LS Peano 分形天线

LS Peano分形天线集成了分形技术的自相似性和空间填充特性,用于检测气体绝缘开关设备(GIS)局部放电(PD)产生的超高频(UHF)信号。首先,我们使用ANSYS HFSS 对LS Peano 分形天线进行了仿真和设计。然后根据优化后的仿真结果制作天线对象。最后,随之进行涉及金属突出缺陷的PD试验。测试结果表明:LS Peano分形天线具有椭球方向性;实测结果表明,该天线的电压驻波比(VSWR)在300 MHz至3 GHz范围内小于4.5,具有较好的局放监测能力;该天线的 VSWR 在 1.1 GHz MHz 至 3 GHz 范围内小于 2,
