摘要
CJ系列交流接触器应用广泛,但是运行噪声大,耗电高,线圈铁心运行温度高,易烧毁。介绍一款节电器,它能有效地解决接触器运行过程中的众多问题。根据接触器工作过程分出的吸合和保持两个阶段的不同特点,采用超小型单片机PIC12F508控制接触器吸合电压和维持电压,实现接触器的无声运行和节能的目的,同时改造了交流接触器线圈,节省大量的铜线。
AC contactors in CJ series is widely used,but there are many problems such as loud noise,high power-consumption,high temperature of iron core coil in the course of operational process.It is of great practical significance to solve the problems.A electricity saving device introduced in the article solved the problems.The noiseless running and electricity saving were achieved by the aid of PIC12F508 to control pick-up voltage and maintaining voltage of AC contactor.Furthermore,much copper has been saved by means of reforming the coil.
