【摘要】 改进了传统交流接触器接通与分断实验装置.新型实验装置的控制模块采用PIC16F818、CD4051等组成,采集模块由互感器、数据采集卡PCI-1711L和基于PC的人机界面组成。通过编制人机界面,实现对信号的采集及其电流电压曲线的可视化显示,为交流接触器接通与分断的动态分析提供了良好的技术条件。更多还原

【Abstract】 The connection and disjunction experimentation device of traditional AC contactors was improved. New device’s controlled module composes of PIC16F81, CD4051 ect., and its acquisition module composes of trasformer, PCI-1711L data acquisition card and man-machine interface based on PC. The connection and disjunction dynamic current and voltage signals and their virtual display were acquired by human-machine interface that can provide excellence dynamic analysis for AC contactors.更多还原
