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.
