Perfect Power Output Section
The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:
1. No need for the additional output filter
2. Directly driving general synchronous or asynchronous motor
3. No de-rating operation on the motor
4. No dV/dt stress on the insulation of motor and cables
5. No torque ripple, extending service life of motors and mechanism
6. No cable length restriction within the acceptable voltage drop.
The general MV VFD has the following protection functions and features:
Overload and over-current
Phase loss and grounding
Over voltage
Overheat
Current limit
Redundant control power supply
Cell Bypass (optional)
Cabinet door alarm
Phase-Lock function
Synchronous Switching between VFD and Grid system
Soft start of motor
High efficiency >98% (VFD at full-load)
Electrical Isolation by the optic fiber
Built-in PID regulator
RS485 communication with the protocol, Modbus as standard, optional Profibus-DP, Ethernet,etc
Accurate fault records, easy to check fault history
Compact structure and layout, customized design is available
- Q: The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
- Can be used, their rated current is not the same, the need to use the inverter over-current overload protection and other parameters for the corresponding changes.
- Q: What is the application of variable frequency speed control?
- Frequency control speed ratio is relatively large, in other words, the speed is accurate, smooth speed. Widely used, the basic works can be used
- Q: A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply
- 3. Take a doorway as an example: choose DN50, N = 7.5Kw enough. About 50 cubic meters / H.
- Q: Can the laptop 1.3a power adapter be used on a 1.5a device?
- Theoretically impossible, because the power is small, but if it is a short period of time is possible, a long time to die.
- Q: Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
- 3. Can try (the effect is not necessarily), for a large inverter and variable frequency motor, and the inverter installed braking unit, braking resistor.
- Q: What is the frequency of `30 points
- AC are frequency, China is 50 Hz, is in a second amplitude of 50 times. To change this frequency, it is necessary to use some electronic components to change the current frequency. General frequency conversion for the tributary motor speed more. So that some equipment can be stepless. Principle, see the first floor just fine, copy the more detailed.
- Q: Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
- Hi, the inverter control is no problem. You need to select the inverter by the load characteristics of the centrifugal pump, consider: Centrifugal pump rated working current, overload capacity, parking whether there is emergency stop request. I used the inverter to control the horizontal centrifuge some time ago.
- Q: Short-term short-circuit converter DC link positive and negative will damage the inverter?
- the switch signal Is the fan running up after the speed line is low, this can be shorted. Pulse is every turn a circle, send two pulses to the speed line
- Q: 22kw.2 pole fan can use Fuji inverter?
- according to the rated name of the fan brand and the inverter rated current control, select the current value match, or slightly larger The
- Q: Three motors, if coupled with the governor speed, is it necessary to add the inverter?
- ?Second, the variable speed: change the way the stator winding wiring to change the cage motor stator pole pairs to speed.
