UPS的概述及配置计算

Overview and Configuration Calculation of UPS

从UL31系列UPS的系统组成介绍入手,阐述了UPS的并机条件及要求,讲述了蓄电池的使用条件及相关知识,分析了新旧蓄电池不能混用的原因及其危害,提出了蓄电池容量测试的技术要求。以加氢联合区域机柜间UPS的选型为例,通过计算对电缆及空气断路器也进行了选型。在对UPS后备时间要求一定的情况下,用几种最常用的计算方法对蓄电池容量进行了配置,根据配置的结果参考蓄电池的技术数据对蓄电池进行了选型,并对几种计算结果进行了比较。

UL31 series of UPS system was introduced, using conditions and requirements of UPS were discussed as well as using conditions and related knowledge of the battery condition, the reasons that old and new batteries can＆#39;t be simultaneously used were analyzed as well as harms of the simultaneous use, and the requirements of the battery capacity test were put forward. Taking UPS selection as an example, types of cable and air circuit breaker were determined through the calculation. In certain circumstances of UPS backup time requirement, several common calculation methods were used to carry out the configuration of battery capacity; According to the result of the configuration, referring to battery technology data, the battery type was determined, and the several calculation results were compared.
