Product Structure 1. Bypass Cabinet (Optional) The by-pass cabinet or switching cabinet may employ isolating breaker, vacuum contactor or the combination, depending on the user¡¯s working conditions. The function of by-pass cabinet is to put the motor into operation in industry frequency grid after the WLD-HVF exits, so as to ensure the continuity of user¡¯s production. The switching cabinet is designed to divert the WLD-HVF output to different motors. 2. Transformer Cabinet Used for installation of Phase-shift transformer, it is dry type transformer with functions of temperature display and over-heat protection, also with insulation grade of H. The secondary multi-winding output provides phase-shift power supply to the power unit. This can greatly improve the current waveform on grid side and reduce the harmonic interference of the equipment to power grid lower of the National Criterion. 3. Power Unit Cabinet Used for installation of power units, which adopted imported high quality components inside, all power units are installed on the sliding seat, it is very easy to replace. 4. Control Cabinet Used for installation of low voltage control components, there are controller, PLC, UPS, Electric siren, DC 24V power supply, Control Power Source Switch, Wiring Terminals, Touch Screen, Operation Button etc. The equipment adopted fiber optical communications, which has a very good EMI restraining performance; The transformer, control cabinet and all power units, are built in temperature protection, so it will be maintenance free. Technical Features Voltage source High-high frequency inverter, it can realize No-step speed regulation, which makes the typical motors into intelligent motors. Low harmonics input and high power factor, the typical value for power factor is 0.95 through whole speed regulation, even more higher, no need for power factor compensation. WLD-HVF output few harmonics, the motor does not generate extra heat and noise. Modularized design of power units, interchangeable and easy to produce and repair, the equipment can find any fault exactly based on advanced diagnostic procedures in MPU. The inverter still can operate even the faults for part of power units exists, if there are faults happen for inverter, the system can switch to power frequency through bypass function. Applicable to all kinds of power grid at home and abroad and suitable for typical high voltage motor. Colorful touch screen, easy to operate and maintenance. Able to realize remote control, DCS operation and communications with Host, and support all kinds of communications interfaces such as CAN, Profibus, Modbus, RS232, RS485 etc. Applied latest components, master control chip adopted TI¡¯s DSP F28335 and ALTERA¡¯s FPGA of EP3C to realize powerful processing capacity; Sampling adopted AD¡¯s AD7606 with 16 bit to ensure control accuracy of the system. The switchgear can satisfy safety requirements, and the pressure-relief channel of high voltage switch can ensure safe use of operators.
