Specifications

Variable Frequency Inverter
1.3KV ~11KV AC Driver Inverter
2.Suitable for motor speed regulation
3.Energy saving solutions

High Voltage 3KV ~11KV AC Driver Inverter  

 

General


CNBM high Voltage Variable Frequency Drives are designed to be highly reliable with high-performance, yet easy to use.It can satisfy users' need for changing the speed of fans or pumps,as well as improve the productivity.

The series are compatible with all types of three-phase medium voltage asynchronous motors.

 

Specification and advantages :

 


1. Voltage resource VFD, direct input of 3,3.3,4.16,6,606 and 10 kV,direct output of3,4.16, 6,6.6 and10 kV,no output transformer necessary. High input power factor, low harmonic current, no power factor corrective capacities and harmonic filters required.
2. Sinusoidal multi-level PWM output waveform, no output filter required, can be directly connected to standard induction motor,no harm to the insulation of the cable or the motor, low harmonics of the motor, reduction of vibration of the shafts or the vanes,with the maximal length of the output cable of 1000m.

3. Friendly human-machine interface.
4. Modular design of the power circuits simplifies maintenance routine.

5.The medium voltage circuits are linked with the controller by the optical fibers,which keep the controller safe and away from the disturbance.

6. The complete fault monitor circuit, accurate fault alarm and protection.

7. Integrated cooling blower

8. The control logic can be conveniently changed with the help of the integrated PLC.

9. Offer both field control and remote control in monitor station, providing convenient controlling options.

10. Support most of the industrial standard protocols (Profibus, Modbus, TCP/IP, etc.)

11. Compatible with industrial standard signal of 0-10V/4-20mA

12. Able to operate at either open loop control or closed loop control status with the integrated PID regulator.

Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
For your situation about the summary of recommendations: First, check whether the motor overload and whether the leakage exceeded, Second, check and clean the inverter fan, if the room temperature is high, add the external fan to the inverter cooling Third, if none of the above, then please check the inverter module is burned, replace the module Fourth, if the inverter is no problem, then the motor and load the problem, if the motor problems are not resolved, then only re-select the inverter, please select the time to increase the margin
Q:Delta VFD-A frequency converter motor number of poles set
According to the actual needs of the motor To provide the required power supply voltage, and then to achieve the purpose of energy saving, speed control, in addition, the inverter there are many protection features, such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency conversion The device has also been very widely used.
Q:What is the principle and implementation of the inverter?
How the inverter works: 1. DC can be converted into alternating current through the oscillation circuit 2. The resulting AC power is then boosted by the coil (in this case, the alternating current of the square wave) 3. Rectify the resulting alternating current to obtain a sine wave
Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
You can only use constant torque type of inverter. Motor selection frequency conversion motor. Driving is no problem
Q:Laptop power adapter current is not the same alternative?
The adapter is the voltage source, the actual output current depends on the size of the load resistance,
Q:Can the laptop power adapter be generic?
Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.
Q:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
With green wave Jie can experience to judge, there may be two possibilities: First, the inverter power selected small. Bipolar motor, not a four-pole motor, the inverter is designed according to the four-pole motor model, so in the inverter selection, can not only look at the power, but also the rated current of the motor;
Q:Why G120 inverter to be equipped with 4-pole motor?
On the upstairs that the motor parameters to be set on the possible, such as voltage, current, power, power factor, rated efficiency, rated frequency, rated speed, motor overload factor
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
and then use the inverter into three-phase AC, 380 volts almost, Can only use the transformer rose to 380 volts.
Q:Octopus AC Servo motor can be driven with ordinary inverter?
If it is synchronous motor, it depends on whether you choose the inverter is compatible with the synchronization machine, most of the incompatible. As you said the situation, the motor 8 pole, may be synchronous motor. Specifically, you can compare the rated speed and rated frequency to see if there is a slip rate to determine whether it is synchronous or asynchronous motor.
