分／合闸电磁铁智能控制模块的设计
Design of the Intelligent Control Module Used for the Breaking and Closing Electromagnet
摘要
Abstract
For some reasons,the coil of the electromagnet often burns,and it seriously affects the reliability of the distribution system.This paper introduced the digital power supply technology and designed an intelligent control module for the breaking and closing electromagnet to control the coil current with a closed-loop.Therefore,the way of the electromagnet exciting can be fundamentally changed.The module can control the exciting time and the exciting current of the coil accurately.With these measures,the coil burning can be avoided,and the operation characteristics of the electromagnet are not affected by the AC phase angle.The coil current can be accurately control over a wide range of input voltage,and it improves the consistency of the operation characteristics,so the operation reliability of the breakers can also be improved.关键词
