摘要
电流行波的采集是输电线路行波故障定位的首要环节,由于行波频率很高,因此了解电流传感器在高频环境下的传输特性是十分必要的,结合霍尔电流传感器在输电线路行波故障定位的应用,列出了磁补偿式霍尔电流传感器的数学模型,对它的幅频、相频特性作了进一步分析,并且讨论了其对行波高频噪声的抑制作用。
Current traveling wave acquisition is a chiefly part in the fault location of transmission line.The frequency of current traveling wave is very high,so it is necessary to study the high-frequency modeling of current sensor.With the Hall-effect current sensor in the fault location,A simple mathematical model of closed-loop Hall-effect current sensor was presented and it's characteristic was also analysed.The restrain effect for high-frequency traveling wave was discussed.
