    UPS电源

    UPS电源是什么?

    UPS(Uninterruptible Power Supply)电源,即不间断电源,是一种将蓄电池(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。

    UPS电源的工作原理

    • 当市电输入正常时,UPS电源将市电稳压后供应给负载使用,此时的UPS电源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电源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电源通常对电压过高或电压过低都能提供保护。
    • UPS电源主要用于给单台计算机、计算机网络系统或其他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。

    UPS电源的类型

    被动后备式UPS电源

    • 指逆变器并联连接在市电与负载之间仅简单地作为备用电源使用。此种UPS电源,在市电正常时,负载完全而且是直接地市电供电,逆变器不做任何电能变换,蓄电池由独立的充电器供电;当市电不正常时,负载完全由逆变器提供电能。

    在线互动式UPS电源

    • 指逆变器并联连接在市电与负载之间,起后备电源作用,同时逆变器作为充电器给蓄电池充电。通过逆变器的可逆运行方式,与市电相互作用,因此被称为互动式。此种UPS电源,在市电正常时,负载由经改良后的市电供电,同时逆变器作为充电器给蓄电池充电,此时逆变器起AC/DC变换器的作用;而当市电故障时,负载完全由逆变器供电,此时,逆变器起DC/AC变换器的作用。

    双变换式UPS电源

    • 指逆变器串联连接在交流输入与负载之间,电源通过逆变器连续地向负载供电。此种UPS电源其供电方式如下:市电正常时,市电经过整流器、逆变器向负载供电;市电不正常时,由蓄电器经逆变器向负载供电。

    UPS电源的应用

    UPS电源广泛应用于:矿山、航天、工业、通讯、国防、医院、计算机业务终端、网络服务器、网络设备、数据存储设备、应急照明系统、铁路、航运、交通、电厂、变电站、核电站、消防安全报警系统、无线通讯系统、程控交换机、移动通讯、太阳能储存能量转换设备、控制设备及其紧急保护系统、个人计算机等领域。
