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 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.
这些断路器应在每极上装有额定值从80%至160%可调的长延时过电流装置。
These circuit breakers should have the long time-delay over-current devices on each polar whose rated value can be adjusted from 80% to 160%.
最好使用交流电源供电，并为设备安装保险丝或额定电流小于2安培的自动断路器，自动断路器还必须与其他负载电流电路分离。
It is recommended that AC power supplies to instruments be protected by fuses or automatic circuit breakers rated at not more than 2 Amperes, and must be separated from any load current circuits.
在最小值熔丝或断路器紧挨最大额定电流40安培的电池。
At a minimum there must be a fuse or circuit breaker located close to the battery rated at 40 amps maximum.
