应急电源

对EPS，UPS及柴油发电机组的3种应急电源进行了技术经济比较，得出EPS作为一种可靠的绿色应急供电电源，尤其适用于当高层建筑消防设施没有第二路市电，又不便于使用柴油发电机组的场合；UPS作为不问断供电设备，广泛应用于计算机、程控交换机、数据处理系统、医疗诊断仪及精密电子仪等不能中断供电的场所。

Emergency Electric Sources

This paper makes technical and economic comparison of three emergency electric sources of EPS, UPS and diesel power set, drawing the conclusions that EPS, as a reliable green emergency electric source, is especially applicable for the occasion that the high-rise building's fire-fighting devices have on second commercial power and the diesel power set is not convenient to use; and that UPS, as a uninterrupted power supply, is widely used in some occasions that the power supply can't be interrupted such as the computer, programmable exchanger, data-processing system, medical diagnoser, and precision electronic machine, etc.
