Abstract

External partial discharge (PD) sensors for the ultra-high frequency (UHF) method are widely used to detect the PD signals in high-voltage power equipment for ease of installation and maintenance. However, conventional external PD sensors detect not only PD signals but also LTE signals; thus, a microwave filter is usually employed. In this work, a UHF filtering antenna (filtenna) is proposed as the external PD sensor to detect PD signals and simultaneously block LTE-band signals. The proposed UHF filtenna is the printed monopole antenna with a built-in interdigital bandpass geometry, which is selected for its compact size. Measurement results show that the proposed UHF-printed monopole filtenna operates adequately in the frequency range of 1 GHz to 1.6 GHz and simultaneously blocks LTE signals significantly.

LTE信号抑制局部放电检测的UHF印刷单极膜

用于超高频（UHF）方法的外部局部放电（PD）传感器被广泛用于检测高压电力设备中的局部放电信号，以便于安装和维护。然而，传统的外部PD传感器不仅检测PD信号，而且检测LTE信号；因此，通常使用微波滤波器。在这项工作中，提出了一种超高频滤波天线（filtenna）作为外部局部放电传感器，以检测局部放电信号并同时阻断LTE波段的信号。所提出的超高频滤波器是具有内置叉指带通几何结构的印刷单极天线，因其紧凑的尺寸而被选择。测量结果表明，所提出的UHF印刷单极子滤波器在1GHz至1.6GHz的频率范围内充分工作，同时显著阻断LTE信号。
