摘要
城轨交通信号系统的各设备负载都由电源屏和UPS统一供电,而能达到各负载分路供电的电气元件则是通过空气断路器完成。在信号系统的维护过程中,空气断路器选择不当,可能带来很多麻烦。因此,从断路器的种类、功能、应用等几方面,详细介绍了断路器选用时的注意事项。
The load of various signal system equipment of urban mass transit were fed by power supply panel and UPS system while each electrical component could adopt air choppers to attain its load shunt supply. If the selection of air chopper could not be made appropriately, lots of troubles may be invited. In terms of classification, function, application of chopper, some considerations in selecting choppers are explained in detail.
