Wanlida High Voltage Frequency Converter - China
price: contact company for price
It is very suitable for motor speed
regulation and energy saving solutions,
especially for high voltage motor of fans,
pump.
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.
