UPS电源的出现与计算机的发展有着密切的关系,建立一个不停电的供电系统对于任何一个用电户都是十分需要的。但是,要把不停电系统建设得这样完善却是计算机系统促进的结果。计算机为什么要配用UPS电源呢?简单地来说,因为市电电网的供电质量差,达不到计算机系统对供电的要求。使用UPS电源是一种提高供电质量的技术措施。
乐万家彩票平台 "UPS"是英文"UninterruptiblePowerSystem"的缩写。其意思是"不间断电源系统"或者称为"不停电供电系统"。也就是说,市电一旦掉电(停电),后备电源几乎是在无断点的状况下,对原有负荷继续供电。UPS电源对保证计算机正常运行是很重要的设备,有了UPS电源,可以保证计算机不丢失信息和数据,可以保证计算机设备的安全,不会划伤磁盘的盘面或者磁头受到损坏。也就是说,随着计算机应用的日益普及,信息处理技术的不断发展,对供电的质量提出越来越严格的要求。

在我国电能质量差,供电只有电压和频率标准,对高次谐波没有要求。并且随时有停电的危险,所以,在计算机供电系统中采用UPS电源是十分必要的。
我国供电电源质量的标准是:400万kW以上的大电网,电压波动为±5%,频率(50±0.2Hz);400万kW以下电网电压波动为±5%~-7%频率为(50±0.5)Hz(对高次谐波分量没有规定)。实际上,在一些地区往往达不到这个标准,还在继续供电,有时电压低得几乎连荧光灯也起动不起来。
