| 摘 要： | 根据超高频分形天线设计的原理,采用平行传输线的电感等效方法分析了Hilbert分形天线阻抗特性,设计出了应用于检测气体绝缘组合电器(gas insulated substation,GIS)局部放电的3阶Hilbert分形天线;采用Hilbert分形天线和微带天线,对金属突出物缺陷产生的局部放电进行了测量,实测结果表明,该天线特性良好,可用于GIS局部放电在线监测;应用Hilbert分形天线和LabVIEW建立了便携式GIS局部放电在线检测及定位系统,进行的局部放电源定位精度满足现场定位要求.

| Abstract: | We design a third Hilbert fractal antenna for partial discharge(PD) monitoring in gas insulated substations(GIS) based on fractal principles,and analyze the Hilbert antenna impedance characteristics using an equivalent inductance method of parallel transmission lines.The PD experiment of metal protrusion defect is conducted employing fractal and microstrip antennae.The test results show that the characteristic of the Hilbert fractal antenna has good performance and can detect the PD signal for online monito... |
