摘要
本文介绍了作为DW框架式空气断路器的主要性能,并说明断路器长延时在低压电路控制电机设备时,选取最佳延时时间的方法,以满足电机设备的正常启动及线路过载或短路时尽快切断供电电路的要求。
This paper introduces the main characteristics of DWframe low-voltage air circuit breaker, and explains the method of circuit breaker's long-time delay choose the best delay when low voltage circuit control the electrical equipments, to meet the electrical equipments'natural starting and cut off power supply circuit when the circuitry over loading or short-circuito
