断路器智能分合闸电磁铁的设计
Design of the intelligent breaking and closing electromagnet for the breaker
摘要
Abstract
The coil of the breaking and closing electromagnet for the distribution system breaker is easy to burn. Aimed at the common failure, this paper designed an intelligent control module for the breaking and closing electromagnet to control the coil current with a closed-loop. Therefore, the excit-ing way of the electromagnet 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 will not be 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. Through co-simulation, the validity of the coil driver circuit and the hysteresis current control mode have been proved. The digital control technology has been introduced to design the control module and some experiments verified the actual effectiveness.关键词
