Rated current DC 额定电压
The object of using DC fuse in tunnels and way of selection were expounded, including the selection of rated voltage and current, and the coordination of circuit breakers.
概述了在轨道交通系统中选用直流熔断器的目的及选用方法，包括额定电压、额定电流的选择，与断路器的配合工作。
The rated current is the DC current value that satisfies both of DC saturation current value and temperature rise current value.
额定电流值指直流重叠允许电流或温度上升允许电流均可满足的直流电流值。
P. S. :The peak current or power should be tested when other output of DC overshoot rated load, and the peak current pulse widens within 100ms.
峰值电流或功率的测试是在其它额定负载时测试，且脉宽小于100 毫秒。
