摘要
设计了一套基于虚拟仪器技术的污秽绝缘子泄漏电流数据采集系统,利用可靠的电压和泄漏电流信号提取系统,保证了提取信号的准确性。采用了双缓冲数据采集模式,实现了对信号的高速、连续、实时采集。系统还具有信号显示、分析和处理等功能,在实验室,通过对实际绝缘子的泄漏电流进行采集,验证了系统设计的正确性和可靠性。
A set of data collection system of polluted insulator leakage current was designed based on virtual instruments technology in this article, and a reliable system ofleakage current and voltage signal extraction system was designed to ensure the accuracy of the extracted signal. The paper used the two-buffer data acquisition mode for high-speed signal acquisition for real-time, and it also has the signal display, analysis and processing functions. The leakage current of actual insulator has been collected in laboratory, which has proved the correctness and reliability of this system.
