据IDC统(tong)计(ji)，我国电(dian)(dian)(dian)(dian)脑故(gu)障的原因(yin)45%主要由电(dian)(dian)(dian)(dian)源(yuan)问(wen)(wen)题引起,在我国，大城市停电(dian)(dian)(dian)(dian)的次(ci)数平(ping)均为(wei)0.5次(ci)/月(yue)，中等城市为(wei)2次(ci)/月(yue)，小城市或村镇为(wei)4次(ci)/月(yue)，电(dian)(dian)(dian)(dian)网至少存在这几种(zhong)问(wen)(wen)题：断(duan)电(dian)(dian)(dian)(dian)、浪涌(yong)、频率震荡、电(dian)(dian)(dian)(dian)压突变(bian)、电(dian)(dian)(dian)(dian)压波动、电(dian)(dian)(dian)(dian)压跌落、脉(mai)冲干扰。因(yin)此(ci)，改善(shan)电(dian)(dian)(dian)(dian)源(yuan)质(zhi)量，从配置一台(tai)UPS电(dian)(dian)(dian)(dian)源(yuan)开始。UPS电(dian)(dian)(dian)(dian)源(yuan)供(gong)电(dian)(dian)(dian)(dian)的要求1、由于比较初(chu)负(fu)载(zai)小，后期运行有可会扩容。必须有冗余设计(ji)，并(bing)且(qie)扩容时不允许负(fu)载(zai)断(duan)电(dian)(dian)(dian)(dian)。2、能配合(he)原有发电(dian)(dian)(dian)(dian)机，作为(wei)供(gong)电(dian)(dian)(dian)(dian)或配电(dian)(dian)(dian)(dian)的故(gu)障冗错(cuo)配置，保障供(gong)电(dian)(dian)(dian)(dian)顺畅。

不间断电(dian)源(yuan)供电(dian)时(shi)(shi)间多长才合(he)适(shi)？UPS能在电(dian)力(li)异(yi)常时(shi)(shi)有足(zu)够的(de)(de)(de)(de)(de)时(shi)(shi)间实施(shi)应急(ji)措施(shi)。一(yi)般(ban)而言5-10分(fen)钟的(de)(de)(de)(de)(de)后备时(shi)(shi)间就足(zu)够了。如果(guo)(guo)需要较(jiao)长的(de)(de)(de)(de)(de)后备时(shi)(shi)间，可(ke)以(yi)购买具有长延时(shi)(shi)功(gong)(gong)能的(de)(de)(de)(de)(de)UPS。不间断电(dian)源(yuan)的(de)(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)(liang)如何计算？目前(qian)市(shi)场(chang)上销售的(de)(de)(de)(de)(de)不间断电(dian)源(yuan)（UPS）多以(yi)VA作为容(rong)(rong)量(liang)(liang)(liang)单(dan)位。V是电(dian)压(ya)，A是电(dian)流，V×A就等于(yu)功(gong)(gong)率，即不间断电(dian)源(yuan)的(de)(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)(liang)。例如，一(yi)台425VA的(de)(de)(de)(de)(de)不间断电(dian)源(yuan)，如果(guo)(guo)其输出电(dian)压(ya)为110V，则(ze)该UPS能够提供的(de)(de)(de)(de)(de)最大电(dian)流为3.86A，超过此电(dian)流值(zhi)就是超载(zai)（Overload）。另(ling)一(yi)种表示功(gong)(gong)率的(de)(de)(de)(de)(de)方法是W，W表示实功(gong)(gong)，VA表示虚功(gong)(gong)。两者之(zhi)间的(de)(de)(de)(de)(de)差别(bie)在于(yu)功(gong)(gong)率因数(shu)。功(gong)(gong)率因数(shu)一(yi)般(ban)在为0.6到0.8之(zhi)间，若低于(yu)0.5则(ze)UPS设计不佳(jia)，在选购UPS时(shi)(shi)，应考(kao)虑功(gong)(gong)率因数(shu)问题(ti)。浙(zhe)江众海智能科技有限公司是一(yi)家(jia)专(zhuan)业提供 UPS电(dian)源(yuan)设备的(de)(de)(de)(de)(de)公司，有需求(qiu)可(ke)以(yi)来(lai)电(dian)咨询(xun)！
