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:Is the laptop power adapter long-haul?
- As long as the power, regardless of your access to the computer, the adapter is working. In fact, not much harm, anyway, five years of notebook life, this thing as long as not deliberately to damage, will be very durable, worse than the important parts of the computer slow. As long as the big brand, nothing Even if you broke, this thing can value a few money? In fact, the proposal or pull it, on the ground stumbling ... ...
- Q:55 瓩 4 pole motor with a frequency of one hour can save much electricity
- it is used in the fan pump load can save about 14-22 kWh, used in the general category, on Multiply your number by 55.
- Q:There is no inverter comes with simple PLC programming function
- The PLC is programmed to handle digital and analog, the core of the entire control system. It can output the digital to the inverter, so that the inverter is reversing, you can output the analog to the inverter set speed, but also through the communication, direct control inverter
- Q:On the notebook power adapter output current and voltage issues
- This current is the maximum current value of the adapter output, Voltage matching, of course, can be charged. It is recommended to select an adapter with an output current value that is slightly larger than the original.
- Q:Delta VFD-F frequency converter how to adjust the number of poles
- P148 look, this is to correspond to the number of poles of the motor, not to adjust the number of poles of the motor
- Q:Fuji inverter motor set the number of poles will not have any effect?
- The number of motor poles set incorrectly, self-learning when the motor parameters are not correct, not the correct parameters of the motor. Inverter control speed is not accurate, and the motor will heat, can not work properly.
- Q:Lenovo g450 laptop power adapter specifications is what?
- Lenovo G450 power adapter Model: ADP-90RH B LENOVO P / N: 36001681 Input: 100-240V ~ 1.5A 50-60Hz Output: 19V $ 4.74
- 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: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: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.
