摘要:
设计了一款用于超高频局放检测的超宽带椭圆缝隙天线. 该天线具有时域保真度高、尺寸较小、馈电简单等特点. 测试结果表明,天线在300～1 500 MHz频段内的回波损耗低于-10 dB,平均等效高度15.7 mm,满足局放检测天线的指标要求. 通过CST Microwave Studio软件对其时域波形保真度进行仿真计算分析,对局放检测时天线的摆放方向提供参考. 结果表明,椭圆缝隙天线在一些角度上的保真度超过0.9,能较好地还原局部放电波形,同时天线较小的尺寸也能更好地适应局部放电现场检测.
Abstract:
An ultra-wideband elliptical slot antenna for UHF partial discharge detection is proposed. The antenna has the characteristics of high time domain fidelity,small size and simple feeding. The test results show that the return loss of the antenna in the frequency band of 300～1500 MHz is lower than -10 dB,and the average equivalent height is 15.7 mm,which satisfies the index of the partial discharge detection antenna. The time domain waveform fidelity is simulated and analyzed by CST Microwave Studio software to provide reference for the placement of antenna in partial discharge detection. The research shows that the fidelities of the elliptical slot antenna at some angles exceed 0.9,which can better restore the partial discharge waveform,and the smaller size of the antenna can better adapt to partial discharge on-site detection.
