中文摘要:

针对气体绝缘组合电器(gas insulated switchgear，GIS)间歇性局部放电泄漏电磁波高灵敏感知要求，利用矩形波导理论结合有限元仿真分析了GIS矩形浇注孔泄漏电磁波传播特性和能量集中频带，结合蝶形天线和梯形渐变巴伦设计原理设计了一款外置式GIS局放检测用背腔蝶形天线传感器。传感器在1 GHz～3 GHz频带范围内最大驻波比小于7，最小驻波比为1.1，平均驻波比为2.9；而在0.3 GHz～1 GHz频带内，最大最小驻波比分别达到42.8和7，平均驻波比能达到20.6。根据设计结果对天线传感器进行试制并进行典型金属突出物间歇性局放试验测试，测试结果表明：所设计的传感器能稳定感知浇注孔泄漏的局放电磁波信号，电磁波信号能量集中频带大于1 GHz，与浇筑孔泄漏电磁波理论分析以及传感器设计驻波比性能结果相符。

英文摘要:

Aiming at the requirement of highly sensitive perception of gas insulated switchgear (GIS) intermittent partial discharge leakage electromagnetic wave. In this paper, the rectangular waveguide theory is used to analyze the leakage electromagnetic wave propagation characteristics and energy concentration frequency band of GIS rectangular pouring hole combined with finite element simulation, and an external GIS partial discharge detection back-cavity butterfly antenna sensor is designed by combining the design principle of butterfly antenna and trapezoidal gradient balun. In the 1 GHz～3 GHz frequency band, the maximum voltage standing wave ratio (VSWR) of the sensor is less than 7, the minimum VSWR is 1.1, and the average VSWR is 2.9; in the 0.3 GHz～1 GHz frequency band, the maximum and minimum VSWR reach 42.8 and 7, respectively, and the average standing wave ratio can reach 20.6. According to the design results, the antenna sensor was trial-produced and tested with intermittent partial discharge of typical metal protrusions. The test results show that the sensor designed in this paper can stably sense the partial discharge electromagnetic wave signal leakage of the pouring hole, and the electromagnetic wave signal energy concentration frequency band is greater than 1 GHz, which is consistent with the theoretical analysis of the leakage electromagnetic wave of the pouring hole and the VSWR performance of the sensor design.
