摘要
研制了一种对GIS快速暂态测量有重要意义的设备——阻抗变换器,本文叙述了其线路原理及性能测试。该阻抗变换器1dB带宽为0～128MHz。用该阻抗变换器建立了一套能用于GIS快速暂态测量的测量系统,该系统具有短上升时间、低下限频率、高分压比。
A most importent apparatus—impedance converter for measurement of VFT is developed. This paper describes the principle and performance test. The bandwidth (±1dB) of this converter is 0～128MHz. With this converter a measuring system was established which can be applied to measure VFT in GIS. This measuring system posseses short rise time, low cut-off frequency and high voltage divided ratio.
