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:Variable frequency pump pressure in the very low flow instability, why?
- . If you want to stabilize the pressure, you must adjust the pipeline characteristic curve is the work point to enhance, so that you can both stabilize the pressure and adjust the flow.
- Q:65w adapter and 90w laptop power adapter What is the difference?
- In general, notebooks have to use power consumption is to decide whether to use 65W or 90W adapter power supply, but not to say that 90W must not use the 65W power supply, but his power is not reached, it is possible that the machine is using some of the features Can not start, for example, external equipment, power supply, if the original request is 90W power supply, but you are using the 65W power supply, external equipment can not work properly. But some cases do not need external equipment, so choose a small 65W power supply is very convenient
- Q:11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
- Frequency converter in the 5-50Hz is constant torque frequency, 50-100Hz is constant power frequency, to see what you want to get the effect
- Q:Jd1a-40 motor speed controller and how to connect the motor
- Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor circuit in the adjustable additional potential to change the motor slip, to achieve the goal of speed. Most of the slip power is absorbed by the additional potential in series, and then an additional installation occurs, and the absorbed slip power is returned to the grid or converted to the energy. According to the slip power absorption application method, the cascade speed regulation can be divided into the motor cascade speed regulation, the mechanical cascade speed regulation and the thyristor cascade speed regulation situation, take the thyristor cascade speed regulation, Suitable for fans, pumps and rolling mills, mine hoists, extruders on the use. Fourth, winding motor rotor series resistance speed control method Fifth, the electromagnetic speed control motor speed method Six, hydraulic coupler speed control method This method is suitable for fan, pump speed.
- Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
- Here is not the inverter can solve the problem, you should first 220V single-phase AC rectifier for the DC (full-wave rectifier plus filter about 310 volts),
- Q:My Lenovo v450 laptop power adapter should be bad how to match?
- Lenovo V450 laptop power adapter is broken, the warranty period is not artificially damaged can be directly to the Lenovo aftermarket replacement adapter can be outside the warranty period to pay maintenance, it is recommended to use the original power adapter the best. Laptop charger (Laptop Charger), that is, laptop charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry called the traditional notebook power adapter for the single band notebook charger (mainly in order to distinguish between the universal notebook charger.)
- Q:On the notebook power adapter output current and voltage issues
- On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator. 3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating. Conditional or buy a large number of good current.
- Q:Laptop adapter
- This principle is not, try, look at how the charge situation, if you can charge, can be filled, just a long time, to no harm However, the heat may be high, long-term so, there is a risk
- Q:What is the common COM point of the PLC and the inverter? Is it positive?
- Generally refers to the common, and most of the negative
- Q:Notebook power adapter on how to look at power
- then the same formula can be used to calculate: power (unit: W) = voltage (unit: V) × current (unit: A). For example: the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we set a formula to know the output power is 20 × 4.5 = 90W.
