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: 4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison
- 4-5.5KW inverter made about 1300 or so, the frequency conversion motor about 3000 The same power of the electromagnetic governor + motor about 4000, the price is almost
- Q: Can different brands of laptop power adapters be generic?
- 1, strictly speaking, different brands of laptop power adapter is not common. Even if the logo on the voltage and current are the same should not be mixed, will cause the power interface or motherboard failure or even damage. 2, with the same brand of different models of the power can be used temporarily, but should not be used for too long. 3, the cottage power adapter is best not to buy the use of hidden dangers, including spontaneous combustion and explosion, try to use the original power adapter.
- Q: Inverter alarm a043, how is it
- When there is a signal failure, if necessary, use DTI Board, if necessary, change P215 In addition, for the synchronous motor (P095 = 12): the inverter is released until the motor is at rest
- 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: The relationship between the power supply of the notebook and the battery
- The relationship between the laptop power adapter and the battery should not be called a power supply relationship, both of which are devices that power the notebook host. The basic relationship between the power adapter, the battery, and the host is as follows:
- Q: Laptop power adapter bad what is the phenomenon?
- Either the power is bad or the machine on the power supply module is bad to repair service
- Q: HP laptop power adapter how to open
- Adapter is broken is difficult to repair, for a barThe common method is to insert the blade into the gap in the middle of the adapter and then pry open
- 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: 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: 400w 6-pole motor should be equipped with much of the inverter?
- 0.75KW just fine, neither waste the inverter resources, but also to meet the occasional overload. And 0.75KW inverter is the standard model.
