摘要
提出一种智能型宽电压交流接触器控制器的研制方案.该控制器对施加在接触器线圈两端的电压采用PWM控制及自适应调节,使普通交流接触器实现了在宽范围交直流输入电压(AC 24～380 V或DC 24～220 V)内稳定可靠工作,具有很好的通用性,大幅度减少了产品种类;同时使接触器还可实现节能、无声运行、无弧或少弧分断、在线设置、显示、远程通信和远程操作等功能,提高了交流接触器的性能指标.
This paper presents a controller＇s design proposal of intelligently controlled AC contactor with wide-range input voltage.The controller can make general AC contactor be operated reliably with a wide range AC or DC input voltage（AC 24～380 V or DC 24～220 V） by using PWM control and self-adaptive adjustment in the coil＇s voltage,and realize the functions of energy saving,silent operation,less arc or no arc break,setting,display,communication,remote operation etc.Accordingly,the performance and characteristic of the contactor will be enhanced greatly and the types of product will be reduced considerably as well.
