三相不间断电源

直流 交流

不间断供电系统不间断供电系统为用户提供不间断直流和交流供电。不间断供电系统包括:•充电整流单元;•带保护和切换单元(UPS配电板)的蓄电池(AB);•带窦滤波器的电压源逆变器(电压源逆变器柜);•备用(旁路)供电通道;•匹配变压器。不间断电源系统的输入输出三相线路电压为220v、380v AC，可根据客户要求提供从15 ~ 60kva的供电范围。蓄电池电压也可根据客户的要求和直流用户的可用性来选择。直流开关柜可与充电整流装置组合在一个机柜中。交流开关柜可与电压源逆变器组合在一个机柜中。电源可以由一个或两个输入端提供。 In case of one input, if voltage at the input is available, power is transferred either via double conversion channel or via bypass channel from input to output. When input voltage is disconnected, load continues to be supplied from accumulator battery and voltage source inverter. As a rule, accumulator battery capacity is selected at the rate of two-hour load power supply. In case of two inputs, consumers are supplied from input with voltage. Only in case of no voltage on both inputs, load is supplied from accumulator battery and voltage source inverter. VOLTAGE SOURCE INVERTER CABINET Voltage source inverter with sinus filter provides load power supply with sinusoidal power-frequency voltage with the lowest form deviation.
