随着电磁阀在工业和日常应用的增多,其功耗越来越被人们所重视。通过对电磁阀驱动电路的研究,设计一套电磁阀节能驱动电路。不仅提高了电磁阀的响应时间,更重要的是降低了功耗,使电磁阀由工作在大电流状态下,变成大电流启动小电流维持的工作状态。减少了由电流过大引起的电磁阀线圈过热,增加了电磁阀的安全性。The power consumption of an electromagnetic valve is drawing increasingly more attentiori as it is widely used in industrial production and daily life. In this study, an energy - saving driving circuit of electromagnetic valves was designed. It can make an electromagnetic valve to start with a high current while work with a low current; thereby the power consumption can be reduced. Besides, it can shorten the response time of an electromagnetic valve and improve the security of the valve.
