Abstract

本实用新型提供了一种价格低廉、性能可靠的不间断电源系统，它的特点是采用普通的不间断电源设备通过接线上的改变，而达到并机的效果。可直接并机的不间断电源因要解决设备之间隔值与相位的瞬间同步问题，通常技术都比较复杂，造价高昂，该不间断电源系统利用新型静态开关技术，用普通的不间断电源达到双机热备份。

Description

高可靠性不间断电源系统
技术领域：
本实用新型涉及一种适合于那些对电源质量要求极高的部门应用的高可靠性不间断电源系统。
背景技术：
在医院手术室、民航导航台、银行中心机房、发电厂等部门，为了保证其设备安全运行，对供电电源提出了极高的要求，通常采用二台经特殊设计可直接并机运行的不间断电源并联运行，以确保当其中一台不间断电源出现故障时，不致于影响电源系统中断供电，这种可直接并机的不间断电源设备因要解决设备之间相互幅值与相位的同步问题，技术复杂，造价高昂是普通不间断电源的几倍甚至更高，无形中提高了用户的运行成本。
实用新型内容：
本实用新型的目的是采用普通不间断电源设备组成一套价格低廉、性能稳定的高可靠性不间断电源系统。
本实用新型由二台普通不间断电源组成，利用不间断电源设备上的静态旁路开关将二台电源设备串联起来组成具有主、备工作模式的电源系统，二台电源设备同时带电运行，只有主机带负载，备机只是处于热备份待机状态，当主机出现故障时，主机上的静态旁路开关立即将有故障的主机脱开，而转由备机投入供电，本系统的特点是结构简单，没有复杂的控制电路，真正的热备份没有转换时间。
附图说明：
附图是本实用新型结构示意图。
具体实施方式：
从附图可以看出本实用新型相关的电路连接关系。二台不间断电源设备接成串联型式，负载接到不间断电源B的交流输出端上，正常工作时不间断电源A上的逆变器3、不间断电源B上的逆变器4分别送出高精度稳压电流至交流输出端上，不间断电源A的交流输出接在不间断电源B的静态旁路开关2的输入端，当不间断电源B正常运行时，其静态旁路开关2是断开的，保证了二台不间断电源的交流输出不会直接并机，不间断电源A只是空载运行，也即热备份待机状态，此刻即使不间断电源A出现故障，对整个电源系统也是没有影响的。
当不间断电源B出现故障，逆变器4停止输出交流电流，静态旁路开关2立即闭合将处于待机状态的不间断电源A的变流输出送到负载R，保证了负载R上电源不中断。
