No backup power supply is required . save much energy bill in the long run 全天候,在阴天和夜晚,利用平时储蓄的能源,继续发光。
Power supply backup power by diesel engine generating of telex building s replace construction 电报大楼供电设备及备用电源柴油引擎发电汰换工程
Backup power for various communication system and signal system in telecom service , mobile field service and railway service 电信、移动、铁道等各种通信、信号系统备用电源。
Dc power supply and backup power supply for the operation of equipment used in electricity utility and nuclear power stations 电力系统、核电站等设备操作直流电源及备用电源。
In a matter of five minutes , the heat went from drafting a potential backup power forward in smith to landing cook , who was regarded as one of the draft ' s better shooters 在约5分钟内,热火新秀从一个大前换到了一个得分后卫,该后卫被认为是今年新秀中最好的射手之一。
It is therefore necessary to have a backup power supply such as the electricity grid to meet the demand when the electricity generated by the renewable energy system is unable to provide the power required 当可再生能源未能提供足够电力,则须要由后备电源(例如市电)补充,以应付电力需求。
When external connected 220v power is failed , specially designed backup power will start automatically , and can maintain a 12hrs ' power supply after the failure of external connected power supply 还专门设计了,当外接220v交流电停电时,自动启动备用电源功能,在外接电源断电12小时内仍可继续工作。
The intermittency of renewable power does not diminish its capacity to contribute wedges ; even if coal and natural gas plants provide the backup power , they run only part - time ( in tandem with energy storage ) and use less carbon than if they ran all year 虽然再生电力会断断续续,但不会减少达成楔形的贡献,即使需要燃煤和天然气发电厂提供备用电力,也只需在部份时间运转(搭配能源储备) ,使用的碳当然少于现今全年无休的情况。
To ensure an uninterrupted operation of communications facilities such as the exchange , we normally use the diesel generator engine unit ( dgeu ) as the backup power . once there is a break in municipal power pipes , dgeu is immediately brought into operation through ats to feed communications facilities , thus guaranteeing a sound offering of telecom services 为保证交换机等通信设备的不间断运行,一般多采用柴油发电机组做为自己的备用电源,一旦市电发生供电故障,即刻启动柴油发电机组,通过市电油机转换屏( ats )进行切换,由柴油发电机组对通信设备提供电源,以保障电信业务的正常运行。
