QYBP Series Variable Frequency Drive (VFD) switchboard for Electric Submersible Pump (ESP) Unit, developed by Dongying Orientsun Electric Co. Ltd., adopts imported low voltage VFD as well as a wideband step-up transformer which boosts the input voltage to ESP working voltage. This is the international control mode for ESP unit, in the domestic commonly known as high-low-high (HLH) control mode. The switchboard has two working modes of variable frequency and fixed frequency.
1.The switchboard reliability is improved by using imported low voltage VFD;
2.The lifetime of motor and cable is prolonged, because the output wave shape of VFD is like the sine wave after reformed by the filter and the wideband step-up transformer.
1.Input voltage: 380~480V;
2.Output voltage: 800~4000V;
4.Output frequency: 0~60Hz;
