摘要
探讨了万能式断路器欠电压脱扣器在启动及工作状态时,采用双绕组线圈和恒流源电路等技术,降低待机状态保持线圈工作电流,来实现欠电压脱扣器在工作状态的低功耗设计。该电路设计方案具有高灵敏度、高可靠度及低功耗的特点。
Investigation was made to the Under-Voltage Release of the Universal Circuit Breaker in the start-up and working condition,using double winding coil and the constant current source circuit technology,which reduced the holding coil current,to achieve the design of the Low-Power Under-Voltage Release.The circuit design has high sensitivity,high reliability and low power consumption.
