      【UPS】

　　UPS，即不间断电源，是将蓄电池(多为铅酸免维护蓄电池)与主机相连接，通过主机逆变器等模块电路将直流电转换成市电的系统设备。主要用于给单台计算机、计算机网络系统或其它电力电子设备如电磁阀、压力变送器等提供稳定、不间断的电力供应。当市电输入正常时，UPS 将市电稳压后供应给负载使用，此时的UPS就是一台交流式电稳压器，同时它还向机内电池充电;当市电中断(事故停电)时， UPS 立即将电池的直流电能，通过逆变器切换转换的方法向负载继续供应220V交流电，使负载维持正常工作并保护负载软、硬件不受损坏。UPS 设备通常对电压过高或电压过低都能提供保护。

　　UPS是针对中国电网环境和网络监控及网络系统、医疗系统等对电源的可靠性要求，克服中、大型计算机网络系统集中供电所造成的供电电网环境日益恶劣的问题，以全新的数字技术研制出的第三代工频纯在线式智能型UPS。直流电源，是维持电路中形成稳恒电流的装置。如干电池、蓄电池、直流发电机等。

　　UPS和直流电源是企业重要的供电保障设备，传统的维护管理包括：①日常巡检外观，定期更换电池、滤波电容、风机等易损件，大修时做电池活化等;②改造或采用换代设备，使用高级工具测试电池性能。这种管理方式企业投入成本高，维护人员工作量大，不易实时掌握设备运行状态和关键数据，设备事故预防能力低。实施在线维护管理可避免传统方式的不足之处，获得良好效益。

　　UPS的中文意思为“不间断电源”，是英语“Uninterruptible Power System/Uninterruptible Power Supply”的缩写，它可以保障计算机系统在停电之后继续工作一段时间以使用户能够紧急存盘，使用户不致因停电而影响工作或丢失数据。
