摘要
双绕组电磁系统大量使用在大中容量交流接触器中,具有节能效果好、抗电磁干扰能力强、极限操作频率高等特点。从绕组形式和切换开关类型两方面对该种电磁系统进行了分析说明,指出了系统可进行功能扩展的地方,并阐述了系统的常见故障。
The double coils electromagnet system is widely used in AC contactor of medium and large capacitywith the characteristics of excellent energy-saving effect, strong ability of anti-electromagnetic interference, highlimit-operating frequency, etc. This paper analyzed the electromagnetic system from two aspects of windings and theswitch type. The system parts with function extension were pointed out and the common faults taking place in thissystem were clarified.
