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: What is the difference between variable frequency motor and variable speed motor?
- The variable frequency motor requirements are high, are special motor, so the general motor can not use the inverter to speed. According to the above formula, it can be seen that increasing the frequency, the motor speed will be faster, reduce the frequency of the motor speed is slow, variable frequency motor core is also a special material, because the ferromagnetic material There is a saturation period, to the saturation period, regardless of whether the motor current increases, the motor will not continue to increase the intensity of the magnetic field,
- Q: Is the speed of the motor controlled?
- Change the external conditions, you can change the motor speed: 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency speed 3. Winding motor rotor series resistance speed control. 4. Slip motor is to change the slip electromagnetic speed
- Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
- Then the motor nameplate on the standard 2P, it must be 2-pole motor, synchronous speed = 60 seconds x frequency (mainland 50Hz) / pole pairs, you can also look at the rated motor speed, about 2940 rev / 60s, so the inverter Set the number of motor poles, is set 2 pole, I hope you can be satisfied.
- Q: Laptop computer about electricity no electricity, is the power adapter problem?
- To judge this is very simple: 1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem 2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter 3. If the two states can work that is the computer charge management part of the poor contact and other issues.
- Q: How to lift Yaskawa inverter base blockade?
- Unlock the base block of Yaskawa inverter: 1. If the Yaskawa inverter reported that the base blockade, we should first check the cause, parameter settings in strict accordance with the recommendations of professional engineers to set.
- Q: What is the adapter?
- Easy Alliance Electronics (China) Co., Ltd. (eNetwork) currently has a different series, different types of adapters, original authentic, and sold at competitive prices.
- Q: Inverter principle eff23
- For vectors such as vector-controlled frequency converters that require a lot of computation, there is sometimes a need for a torque calculation CPU and some corresponding circuits. Frequency control is by changing the motor stator winding power supply to achieve the purpose of speed.
- Q: Will the laptop's power adapter is not the original good?
- As long as the power and current are equal or slightly larger than the original adapter, but the voltage must be equal to the original adapter on the line.
- Q: 55 瓩 4 pole motor with a frequency of one hour can save much electricity
- Such as: 55KW motor full load operation, 1 hour with 55 degrees of power (according to the motor power slightly different changes),
- Q: Three sets of batteries (540V) DC power supply U / f inverter.
- It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
