Company name - * 01-04-06 - ABB Characteristics 特性 Ultimate flexibility in motor voltage. The customer can choose practically any motor voltage. 对电机电压的适应性，用户可以根据实际情况选择电机电压 Reasonable cost. The transformer is not over dimensioned as in drives where no sine filter is used. 节省费用，升压变压器容量比没有正弦波滤波器的传动所需的容量要小 No extra stress of motor coil insulations. No bearing current due to sine filter and galvanic isolation provided by the transformer. 不要求特殊的电机线圈绝缘。由于有正弦波滤波器和变压器的隔离作用不 会产生轴承电流 Low motor noise. The voltage and current waveforms are sinusoidal and therefore no additional noise due to converter is produced. 低电机噪音，输出的电压和电流为正弦波形 Long cables allowed. 允许长的电机电缆 Can be installed in floating networks. 可以安装在浮地电网 Advanced control methods. 先进的控制模式 Pump life time is maximised 提高泵的使用寿命 Up to 100% starting torque by step-up transformer 通过使用升压变压器可以得到100%的起动转矩 Cables several kilometters long may be used as there are no voltage reflections 允许使用几千米长的电缆，而没有电压辐射 Long cable voltage drops needs to be compensated by output transformer secondary side 电缆上的压降可以通过输出变压器来补偿 Characteristics 特性 ACS800 M ACS800+ NSIN Motor cable e.g. 500-1000 m M ACS800 + NSIN Total motor cable e.g. 700-2000 m Multiple parallel motors - total cable length long M M M M M M M M Drive with output transformer (results are scaled) -1500 -1000 -500 0 500 1000 1500 Voltage (V) Drive output voltage Transformer Primary voltage Transformer Secondary voltage ACS800 LV ESP VSD System : ACS800 低压潜油电泵调速系统 Downhole Wellhead Topside Input Transformer 输入变压器 Step up Output Transformer 输出升压变压器 12 pulse Input Rectifier 12 脉波整率 Inverter 逆变器 Downhole Cable 电缆 Motor 电机 Pump 泵 M P JB DC bus A DC bus B M P JB M P JB M P JB M P JB M P JB M P JB M P JB M P JB M P M P JB M P JB M P JB M P JB M P JB M P JB JB Inp
