摘要
UPS是一种以整流器、充电器、电池组、逆变器、监控器等装置组成的、能够为电气负载提供恒压恒频电源的储能设备。它是保障电力供应和优化配电质量的有效手段,并逐渐发展成为质量稳定、性能可靠的自动化局部供电中心。目前,采用多组UPS冗余并联和在线维护(热插拔)技术,大大增强了电源的可靠性。蓄电池是UPS的心脏,必须对蓄电池长期跟踪测试,优化充、放电方法,实行状态管理。
Consisting of a rectifier, charger, battery hank, inverter, monitor and other devices, UPS can offer the energy storage with constant voltage and frequency power source for the electrical load. It is an effective measures for power supply and optimized energy quality. Now it is becoming a center of automatic local power supply with stable quality and reliable performance. The application of multi - group UPS redundant parallel and online maintenance （heat insert） technology has enhanced the reliability of power sources greatly.
