摘　　要：用天线理论对用于GIS局部放电检测的超高频传感器频率响应特性进行了分析及实测。结果表明 ,理论计算和实测结果能较好地吻合。同时 ,对电容式传感器在UHF波段的灵敏度随频率的变化关系及传感器结构对频率响应特性的影响进行了研究 ,这些结果具有实用的工程意义。The frequency response (FR) characteristics of the ultra high frequency (UHF) sensors used for detecting partial discharge in GIS are analyzed by the antenna theory and measured in laboratory. It is shown that the calculated results are in good confirmity with the measured ones. In addition, the sensitivities of the capacitive sensors as function of frequencies in UHF band and the influences of the sensor constructions on the frequency response characteristics are studied.
