各種備用電源的(de)特點

1、UPS電源的特點

1）可實現不(bu)間斷供(gong)電。

2）長期(qi)帶(dai)載工作。

3）帶電機(ji)類負載需(xu)要擴(kuo)容或加(jia)緩(huan)啟(qi)動措施。

4）蓄電池處(chu)理有生態破壞問(wen)題，應(ying)做環(huan)保處(chu)理。

2、柴油發電機特點

1）容量大，噪音大，產生公害。

2）排煙(yan)中有大量的二氧(yang)化硫，污(wu)染大氣，嚴重(zhong)影響(xiang)環保(bao)。

3）在(zai)高層建筑中，柴(chai)油發電機組一(yi)般(ban)放在(zai)地下室，設計難度大，造價高，進(jin)風、冷卻、排煙(yan)、減震、消音等設施(shi)都(dou)需要(yao)充分考慮(lv)，需要(yao)專(zhuan)用房間。

4）日常維護必須到位，工作量(liang)大(da)。

5）存在火(huo)災隱(yin)患。因為內部(bu)有一油罐，萬一失(shi)火(huo)，后果難以設想(xiang)。發電(dian)機房內需使用水噴霧滅火(huo)，費用則越來(lai)越高。

3、應急電源（EPS電源）的特點

1）電(dian)網有(you)電(dian)時(shi)，處于靜態(tai)，無噪音(yin)(yin)；無市電(dian)時(shi)，其噪音(yin)(yin)小于60db。不需排煙、防震(zhen)處理。而且具有(you)無火災(zai)隱(yin)患的特點。

2）自動切換(huan)(huan)，可實現(xian)無人值(zhi)守，節能，電(dian)網供(gong)電(dian)與EPS電(dian)源供(gong)電(dian)相互切換(huan)(huan)時間為(wei)0.25S，特(te)殊情況下可實現(xian)零切換(huan)(huan)。

3）可在不加軟(ruan)啟動設(she)備的情(qing)況(kuang)下直接帶(dai)電機類負載。

4）使(shi)用可靠、主(zhu)機壽命長達20年以上(不包括蓄電池)。

5）適應(ying)(ying)惡劣環境，可放置于(yu)地下室或配電室，甚至(zhi)建(jian)筑豎(shu)井(jing)里，可以緊靠應(ying)(ying)急(ji)負荷(he)使用(yong)場所(suo)就地設置，減(jian)少供電線(xian)路。

6）蓄(xu)電池處理有生態破(po)壞問題，應做環保處理。

EPS電源與UPS電源的區別

1、負載性質的區別

UPS電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)對象(xiang)主要(yao)是計算機和網絡設備，負(fu)載性(xing)質較低，目前規定(ding)UPS電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸出的(de)功率因(yin)數為(wei)0.8。而EPS電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)主要(yao)用(yong)于電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)應急保障，通常負(fu)載性(xing)質為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)性(xing)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)容性(xing)。有些負(fu)載是要(yao)求斷電(dian)(dian)(dian)(dian)(dian)(dian)后才(cai)投入(ru)使(shi)用(yong)，所有EPS電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)必須(xu)能(neng)提供(gong)(gong)很大的(de)沖擊電(dian)(dian)(dian)(dian)(dian)(dian)流，通常要(yao)求在120%負(fu)荷的(de)情況下能(neng)持續供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)10分鐘以(yi)(yi)上。 UPS電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)額(e)定(ding)容量以(yi)(yi)KVA為(wei)單位，EPS電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)額(e)定(ding)容量以(yi)(yi)KW為(wei)單位。

EPS電(dian)源主(zhu)要用于消防類(lei)負荷以(yi)及一些對切(qie)換時間要求不高，但需要持續供電(dian)的設備(bei)。UPS電(dian)源主(zhu)要用于計算(suan)機(ji)、數字(zi)信息(xi)系統等對供電(dian)質(zhi)量要求較高的負載。

2、功能的區別

EPS電(dian)(dian)(dian)(dian)(dian)源和(he)UPS電(dian)(dian)(dian)(dian)(dian)源都具(ju)備市(shi)電(dian)(dian)(dian)(dian)(dian)旁路(lu)和(he)逆變(bian)電(dian)(dian)(dian)(dian)(dian)路(lu)，但(dan)是EPS電(dian)(dian)(dian)(dian)(dian)源只具(ju)有(you)持續供電(dian)(dian)(dian)(dian)(dian)功能(neng)，對(dui)逆變(bian)切換時間要(yao)求不高，目(mu)前(qian)大部分EPS電(dian)(dian)(dian)(dian)(dian)源還具(ju)備蓄電(dian)(dian)(dian)(dian)(dian)池單體檢測(ce)功能(neng)。EPS電(dian)(dian)(dian)(dian)(dian)源在(zai)市(shi)電(dian)(dian)(dian)(dian)(dian)中斷后才進行逆變(bian)輸(shu)出，電(dian)(dian)(dian)(dian)(dian)源利用率高。

而(er)UPS電(dian)(dian)(dian)源一般強調(diao)其三大功能(neng)：對市(shi)電(dian)(dian)(dian)進行(xing)穩(wen)頻和(he)穩(wen)壓處理；對切換時間要求極高(gao)的設(she)備供(gong)(gong)電(dian)(dian)(dian)；凈化市(shi)電(dian)(dian)(dian)。日常著(zhu)重整流和(he)逆變的雙變換電(dian)(dian)(dian)路供(gong)(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)能(neng)利用率不高(gao)。但是(shi)UPS電(dian)(dian)(dian)源不僅(jin)僅(jin)是(shi)在斷電(dian)(dian)(dian)時逆變供(gong)(gong)電(dian)(dian)(dian)，還可(ke)以在市(shi)電(dian)(dian)(dian)出現電(dian)(dian)(dian)壓偏(pian)差大、浪涌等異常情(qing)況(kuang)時提供(gong)(gong)穩(wen)定的電(dian)(dian)(dian)力輸(shu)出，這是(shi)EPS電(dian)(dian)(dian)源所不具備的。

3、應用領域上的區別

在我國EPS主要用于(yu)消防類負荷及一些對供(gong)電質量要求不太(tai)高，但(dan)需保證連續供(gong)電的用電設備。僅強調能持續供(gong)電這一功能。EPS用于(yu)消(xiao)防(fang)(fang)負(fu)荷時，其產品技術受公安部消(xiao)防(fang)(fang)認證(zheng)。UPS一般用于計算(suan)機及數字信(xin)息(xi)系統等(deng)場合。要(yao)求(qiu)供(gong)電質量較(jiao)高(gao)的(de)負載，主要(yao)強調逆(ni)變切(qie)換時間(jian)、輸出(chu)(chu)電壓、頻(pin)率穩定性(xing)、輸出(chu)(chu)波(bo)形的(de)純正、無各種干擾等(deng)。
