摘要：IEC62040-3提出了UPS 按性能分類的方法，其目的是使用戶可以在相同的基礎(chǔ)上，對(duì)功率相近的不同廠家的UPS 產(chǎn)品進(jìn)行比較。UPS廠家應(yīng)按IEC62040-3規(guī)定對(duì)其產(chǎn)品進(jìn)行性能分類代碼的標(biāo)識(shí)；用戶應(yīng)選用已標(biāo)識(shí)性能分類代碼的UPS 產(chǎn)品。
　　本文闡述了IEC62040-3規(guī)定的UPS 性能分類方法和標(biāo)準(zhǔn)化的UPS 系統(tǒng)結(jié)構(gòu)，并介紹了高可用度的并聯(lián)冗余UPS和分布冗余UPS系統(tǒng)。 敘詞：UPS性能分類 雙變換 并聯(lián)冗余 分布冗余 雙母線 Abstract：IEC62040-3 put forward the method for classification of UPS by performance. The objective of classifying UPS by performance is to provide a common base on which all UPS manufacturer’s/supplier’s data are measured. This enables purchasers, for similar UPS ratings, to compare different manufacture’s products under the same measurement conditions.　UPS will be classified by performance code in accordance with this standard. UPS users should generally avoid using the UPS without performance code.
This paper describes the new UPS classification scheme and the standardized UPS system architecture .Finally parallel redundant and distributed redundant UPS with high availability are presented.
