| 摘 要： | 运行中的GIS内置传感器因其不易拆装,很难对其可靠性及有效性进行校验。根据GIS的结构特点以及特高频信号在GIS内的传输特点,提出一种对内置式特高频传感器的有效性进行校验的方法。通过在相邻传感器注入特高频信号并对信号幅值进行检测,通过检测及计算结果来判断特高频传感器的有效性,经现场验证,该方法简单有效。

| Abstract: | It is difficult to verify the reliability and effectiveness of the GIS built-in sensors in operation because they are not easy to disassemble and assemble.According to the structural characteristics of GIS and the transmission characteristics of UHF signals in GIS,a method for verifying the validity of the built-in UHF sensors was proposed.By injecting UHF signals into adjacent sensors and detecting the signal amplitude,the effectiveness of UHF sensors was judged through detection and calculation results.Field verification showed that the method is simple and effective. |
