摘　　要：为准确测量EAST离子回旋波加热(ICRF)系统中的驻波电压,设计了一款传输线驻波电压测量系统。该系统利用传输线上的电压探针阵列,经检波器、光电隔离器和采集卡接入PC机的数据处理模块,并用LabVIEW数据采集处理软件将采集到的信号进行拟合。测量结果能够清楚地得到各电压探针的电压值,拟合结果具有明显的驻波特性,同时还可以将探针信号作为发射机的保护信号,用于保护发射机安全稳定运行。In order to accurately measure the standing wave voltage in ion cyclotron range of frequencies(ICRF)wave heating system on EAST,a standing wave voltage measurement system along transmission line is designed.The voltage probes array on transmission line had been used in this system,through the power detector,photoelectric isolator and acquisition card to access the data processing module of PC.After that,the collected signal is fitted by the LabVIEW software used for standing wave voltage calculation.From the measurement results,it is clear that the standing wave voltage of ICRF wave heating system had been successfully detected.Meanwhile,one of the probe signal can also be used as the protection signal of transmitter to guarantee the safe and stable operation of transmitter.
