UPS電源的工作方式根據(jù)用電設(shè)備對供電可靠性和連續(xù)性的要求可分為單一式、并聯(lián)式、冗余式和并聯(lián)冗余式等方式。
根據(jù)用電設(shè)備對供電可靠性和管理方便的要求也可分為分散式、集中式、分散與集中相結(jié)合三種方式。分散式UPS供電采用的設(shè)備容量都比較小，支持時間較短，適合用于一些辦公區(qū)和控制室;集中式UPS供電適合一些要求支持時間較長和較大型的計算機(jī)網(wǎng)絡(luò)機(jī)房等。
應(yīng)當(dāng)根據(jù)甲方需求來確定采用哪種UPS的供電方式和容量。集中設(shè)置的UPS電源容量的統(tǒng)計需由設(shè)計方與業(yè)主密切配合，并考慮所選UPS產(chǎn)品的轉(zhuǎn)換效率。尤其是功率較大時，UPS轉(zhuǎn)換效率非常重要，效率高就可節(jié)省初期投資和長期能源損耗的費(fèi)用。
電池的使用壽命與環(huán)境溫度密切相關(guān)，電池處于較低溫度時，蓄電池中的鋅板容易粉化，失去蓄電性能，造成永久性損壞；溫度過高時，電池的容量也會下降，情況嚴(yán)重時會造成永久性損壞。根據(jù)電池生產(chǎn)廠家的技術(shù)規(guī)范，電池的最佳使用溫度是2~25℃，在該溫度范圍使用，可延長電池的使用壽命。
The working mode of UPS power supply can be divided into single type, parallel type, redundant type and parallel redundant type according to the requirements of electrical equipment for power supply reliability and continuity.
According to the requirements of power supply reliability and convenient management of electric equipment, it can also be divided into three ways: decentralized, centralized and the combination of decentralized and centralized. The equipment capacity of distributed UPS power supply is relatively small and the support time is short, which is suitable for some office areas and control rooms; Centralized UPS power supply is suitable for some large computer network rooms requiring long support time.
The power supply mode and capacity of UPS shall be determined according to the needs of Party A. The statistics of centralized UPS power supply capacity shall be closely coordinated by the designer and the owner, and the conversion efficiency of the selected UPS products shall be considered. Especially when the power is large, the conversion efficiency of UPS is very important. High efficiency can save the cost of initial investment and long-term energy loss.
The service life of the battery is closely related to the ambient temperature. When the battery is at a low temperature, the zinc plate in the battery is easy to pulverize, lose the power storage performance and cause permanent damage; When the temperature is too high, the capacity of the battery will also decrease, and permanent damage will be caused in serious cases. According to the technical specifications of the battery manufacturer, the best service temperature of the battery is 2 ~ 25 ℃, which can prolong the service life of the battery.
