基于CPLD的真空断路器智能控制单元的设计

Design of Intelligent Control Unit for Vacuum Circuit Breakers Based on CPLD

基于CPLD技术设计了真空断路器永磁操动机构的智能控制单元 ,该控制单元包括输入、输出和控制三个模块。描述了该控制单元的结构、逻辑控制功能 ,以及实现该控制单元的硬件电路和软件。对控制断路器的逻辑功能进行了仿真 ,并在断路器上进行了试验验证。

The intelligent control unit(ICU) of operation mechanism with permanent magnetic actuator for vacuum circuit breaker is designed based on CPLD in this paper.ICU consists of the input/output module and the control module.The present paper describes the structure and the function of logic control of ICU,and shows the circuit block diagram of ICU.The logic function of controlling circuit breaker is simulated.The experimental results of ICU on a vacuum circuit breaker show the logic control function and driving are correct.
