摘　　要：介绍了一种采用罗柯夫斯基线圈做传感器的雷电流波形的自动记录装置 ,该装置将大电流转化为低电压测量 ,其数据采集、处理用以单片机为核心的系统实现 ,将 A/D转换的结果存储至 RAM中 ,数据可打印或显示 ;初步试验表明该装置可用于雷电流的现场测量并有一定的抗干扰能力。In this paper an automatic device which can record the high current is introduced. The high current is transformed to low voltage which can be measured, the formula of transformation is also educed. The data acquisition and processing is carried out by the system whose core is a singlechip. The sample data are stored in the RAM, then the data can be displayed or printed. The device has the capability of anti-interference and precision.
