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。
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 disjunc-tion dynamic current and voltage signals and their virtual display were acquired by human-machine interface that can provide excellence dynamic analysis for AC contactors.
