Product Structure
AC Motor Drive Variable Frequency Drive Consists Of By-pass Cabinet, Transformer Cabinet, Power Unit Cabinet And Controller Cabinet From Left To Right.
Technical advantages of AC Motor Drive MV Variable Frequency Drive
No need of extra output filtering device
Directly driving the general medium voltage synchronous or asynchronous motor and the temperature of the motor will not be increased.
No need of motor derating operation
No dv/dt damage to insulation of motor and cable
No torque ripple induced by harmonics, and the service life of motors and mechanism devices can be extended
No cable length limited when voltage drop is in the allowable range.
Besides the above advantages, AC Motor Drive MV Variable Frequency Drive has the following functions and features:
Protection of overload, overheat, over-current, open-phase, grounding, over-voltage, negative sequence.
Current limited function
Interlock protection of control power supply
Two sets of control power hot standby for redundancy
Power cell by-pass function
Control cabinet automatic bypass function
Cabinet door opening alarm function
Lock-phase function
Synchronizing switch function between variable frequency and power frequency (optional)
Soft start of motors, no impact to mechanical equipment and network
Voltage source High-high variable frequency drive, it can realize No-step speed regulation, which makes the typical motors into intelligent motors.
High quality power input: By phase shifting of the secondary winding and multi-pulse diode rectifier, isolated powers can be acquired and supplied for power cells. (18 pulses for 3/3.3kV, 30/36 pulses for 6/6.6kV, 48/54 pulses for 10/11kV) By using the technique of multi-pulse rectifier, the harmonic current could be eliminated greatly.
Power cell communicate with controller through optic-fiber, completely electric isolated
Inner set PID regulator, can realize running in closed-loop
Multiple communication methods with host computer, isolated RS485 interface, standard MODBUS RTU, communication protocol, PROFIBUS DP (optional), industrial Ethernet communication protocol (optional)
Accurately fault records, can inquiry information and locate fault
Compact construction, reasonable layout (can do customer-design)
Very good protective design to dust, ferrum pulveratum, acid mist, moisture etc.
Bypass cabinethas a function of "five-protection", meanwhile, it has a pressure relief channel to ensure the safety of operators.
Modularized design of power units, interchangeable and easy to produce and repair.

- Q: Can different brands of laptop power adapters be generic?
- First look at the specifications, voltage, power, current, are matched after looking at the interface, all the same can be used, or else the two are bad.
- Q: Can the laptop's power adapter be used for years?
- In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, which is the so-called "travel power adapter", if the city voltage to only 110V country , This feature is very useful, and some parallel notebook computers are sold only in the origin, there is no such compatible voltage design, or even only a single 110V input voltage, in our 220V mains voltage will be burned to burn.
- Q: The laptop power adapter is hot
- Notebook power adapter in the power after the use of hot is a normal phenomenon, do not worry, no danger, it will not explode. The length of this time does not matter, in the use of one or two hours will become very hot, but will always keep this temperature. And the notebook's power adapter shell are high temperature, will not burn. Notebook power adapter in addition to hot, you may hear the sound, the sound is not, very small. This sound is not a big problem, it is the power adapter power after the power filter sound, so plug in the plug after. Any power adapter basically has a sound. You can listen carefully, the surrounding environment is particularly quiet when you can hear. Power adapter is a transformer, inside the transformer coil in the AC will produce Zizi sound. Some power adapter use a long time will have this sound, but no big problem, you can continue to use. As long as the sound is not high outrageous do not control. Laptop power adapter hot and sound basic are considered normal, unless the temperature is too high or even damage to the shell or the sound is very obvious, this is a problem. The general does not affect the use of the adapter bad to buy a can. Notebooks have to protect the isolation circuit, do not worry about damage to the notebook.
- Q: Is the inverter output current proportional to the output torque?
- When 50HZ or more, the voltage is not increased, the magnetic flux decreases. P = T * n / 9550, if the motor output torque does not change, the current will increase, the motor heat overload
- Q: Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole
- Whether the motor is abnormal roar, if any, you can adjust the inverter parameters in the motor carrier frequency
- Q: Lenovo g450 laptop power adapter specifications is what?
- Input: 100-240V ~ 1.5A 50-60Hz Output: 19V - 4.74A
- Q: 22kw.2 pole fan can use Fuji inverter?
- Fan with Fuji? Money more people silly ... no comment ..
- Q: How to choose a power adapter
- Your notebook power part of the compatibility is very good, in a certain voltage range of power can be used long, but still please note on the notebook subject.
- 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.
- Q: Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
- If you buy the inverter and the motor can match, it is certainly the quality of the inverter.
