摘　　要：对高压设备绝缘特性带电检测仪信号采集系统的主要组成——电流传感器及波形采集系统进行了研究．阐明了电流传感器的设计思想，提出了波形采集系统的设计方案．讨论了传感器的电路结构及屏蔽措施，给出了在实验室条件下的试验结果．分析得出数据采集速率与带电测试准确度之间的关系．The signal sampling system of the on line high voltage insulation diagnosing device mainly made up of two parts, current sensor and waveform sampling system, is studied in this paper. The design methods for the current sensor and waveform sampling system are put forward. The structure and shielding of the current sensor are discussed, and the laboratory testing results are given. Finally the relation between the sampling rate of the data sampling system and accuracy of the device is analyzed.
