Product Structure of MV VFD AC Motor Drive 3KV 6KV 10KV
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 MV VFD AC Motor Drive 3KV 6KV 10KV
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: A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
- If it is normal V / F control, then do not need to modify too many parameters to limit the frequency limit of 50%
- Q: What are the types of power adapter used in notebooks?
- Notebook function is limited, such as power requirements of only 50-70 watts (W). In recent years, power requirements have risen above 100 W, but the expectations for weight and size have not improved accordingly. In addition, the need to meet the low standby power performance in the specification, external power (EPS) efficiency requirements and IEC1000-3-2 harmonic power requirements above 75 W make this challenge more difficult to deal with. This article explores new trends that enable power supply manufacturers to address these challenges and provide alternative solutions to choose from.
- Q: Laptop power adapter is broken, which brand is better domestic
- What brand of your laptop brand? It is best to be original,
- Q: Can the laptop power adapter be generic?
- Output voltage, current, interface can be used as well.
- Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.
- Q: On the notebook power adapter output current and voltage issues
- This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!
- Q: My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
- Poor match, the program is unreasonable Current 1.5A, choose a single-phase 220v power supply, 370-500w inverter it
- Q: Laptop power adapter is used to do what
- Power and charge the notebook. Equivalent to power, mobile phone charger.
- Q: Three sets of batteries (540V) DC power supply U / f inverter.
- This is the reason for the battery characteristics, your group of easy to burn the battery discharge characteristics of the curve should not be partial to engage, so easy to burn. Ultimately it is your group of battery quality is relatively poor!
- Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together
- Pairs of modules are connected in a phase branch The phase output is derived from the neutral point between the modules
