电源质量对负荷的影响电源质量对负荷的影响包括：电源电压允许压降范围及持续时间；日常电压失真范围、频率精度。负荷对电源质量承受力强，可以简化系统提高可靠性降低成本，比如增加旁路时采用一般为0．02~0．2S瞬时停电转换方式。日常电压失真，频率精度一般不是特殊负荷，市电电源下足够运行，一般不需考虑电源对负荷的影响。对电源电压瞬时降低和断电敏感的计算机，电源电压降低10％半个周期就会产生影响。则需要提供电源。3.3UPS容量选择根据下列因素，特性、计算负荷、冲击电流、峰值电流、过载能力、负荷突变状况选择UPS容量。有效负荷容量用下述数值作补偿。

Sante UPS power supply 3C20KS20KVA UPS Type Generally, the UPS isselected as economically as possible according to the requirementsof power reliability, function requirements, and ease of use.Select a UPS based on the load characteristics. From the practical,easy to choose, UPS can be divided into three categories: singleoperation, backup operation; There is bypass conversion, no bypassconversion; The inverter runs normally. The power supply runsnormally. 2, the characteristics of UPS power supply singleoperation UPS, used for general important loads; It is used forloads with different input and output frequencies, or with littleimpact on the mains and high frequency accuracy requirements.Backup operation UPS, the use of multiple non-power failuredevices, with backup function, when part of the failure, othernormal parts to the load power supply, for particularly importantloads. A bypass UPS is available, and loads can be supplied by themains and inverters, improving power supply reliability. Most UPSare configured with bypass mode. No bypass converter UPS is usedfor loads with different input and output frequencies, or with highrequirements for mains frequency and voltage accuracy. Usually theinverter runs, the load has high requirements on the quality of thepower supply, and is not affected by the mains, power supplyvoltage and frequency. In normal mains operation, the load has lowrequirements on the quality of the power supply, high requirementson reliability, and high efficiency without changing operation.When used, the three operating modes are combined according to theload nature.

使用范围：
太阳能路灯、庭院灯、杀虫灯、信号灯，UPS不间断电源，警报系统，消防、应急照明系统，邮电通信，电力系统，电厂电站的开关控制及事故处理，银行不间断系统，和电讯设备，电动玩具,安全防卫系统，医疗设备，太阳能系统，船舶设备，控制设备，电子仪器及其它备用电源。当电流回复到额定电流值以下，不停电转换到整流器，逆变器供电。(2)关于峰值电流能承受峰值电流的UPS；容量=有效负荷容量X峰值电流（大值）/UPS额定电流；峰值容量一般为有效容量2倍；峰值系数为2．5以上的UPS，峰值电流承受能力为250％PA上，一般不超出UPS额定容量．可以直接采用，不需补偿。(3)关于过载UPS过载能力一般在有效负荷的1．1倍以上，负荷过载超过1．1倍应对UPS进行保护。(4)负荷突变多数UPS负荷突变0100％范围内，输出电压波动可以控制在_10％l~A内。对有效负荷容量可以不作补偿。(5)发电机-UPS配合在某些场所中UPS在市电停电后转换至自备发电机供电。在自备发电机供电时，应能提供UPS启动时大冲击电流，而不会影响发电机运行。a.选择整流设备较低启动电流UPS。例如12脉冲整流器，则自备发电机容量应该是整流器的2倍。
