接触器节能抗晃电控制器产品的开发

介绍了一种接触器节能抗晃电控制器产品的技术方案和工作原理。控制电压Us反时限脉动全压起动技术,减小了触头合闸时的振动,延长了其使用寿命;采用宽电压、恒功率输出的低压直流吸持技术,使小功率接触器节能≥70%,中、大功率接触器节能≥90%,杜绝了晃电＂失压＂引起的跳闸事故;采用全压自动分时分批再起动技术,又使接触器晃电＂失电＂跳闸后,尽快地实现了再起动,保证了流水线生产的连续性,从而最大限度地减小晃电跳闸断电给企业造成的损失。

Development of Contactor’s Controller with Energy-Saving and Anti-Interference Electricity

This paper introduced the technical scheme and working principle of a kind of contactor＇s controller with energy-saving and anti-interference electricity. Using the control voltage Usand inverse time pulsation pressure starting technology can reduce the vibration of conactor when switching and prolong its service life. Low voltage DC holding technology with wide voltage and constant power output can make the small power contactor＇s energy-saving more than 70%,medium and high power contactor ＇s energy-saving more than 90%,so as to stop the tripping accidents caused by interference electricity and lost voltage. And total pressure automatic time-sharing re-starting technology can make contactor re-starting as soon as possible when tripping,which ensures the continuity of the production line and reduce the losses.
