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: How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
- The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah
- Q: How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
- With the inverter control, then you do not need multi-speed motor, because the inverter can directly control the motor speed, if the two together, the formation of a waste.
- Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
- Then the motor nameplate on the standard 2P, it must be 2-pole motor, synchronous speed = 60 seconds x frequency (mainland 50Hz) / pole pairs, you can also look at the rated motor speed, about 2940 rev / 60s, so the inverter Set the number of motor poles, is set 2 pole, I hope you can be satisfied.
- Q: Does the teacher know the working principle of the inverter?
- At present the main inverter is Mitsubishi you can go to their domestic sales site to find a specific inverter manual has a detailed explanation Also popular said that the inverter is to change the operating frequency of some mechanical equipment control devices, such as motors, pumps, etc.
- Q: Lenovo laptop power adapter side of the feet which is positive
- Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop.
- 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: With the inverter control fan 37Kw4 pole with what model inverter
- Universal or light-load type, the brand is not limited.
- Q: Do not the laptop directly connected to the power adapter?
- "Notebook do not power adapter", can only use the internal lithium battery power supply work. It can not directly use 220V AC power supply for it. 1, because the notebook product design power supply standard, is to use the matching power adapter power supply. That is, the power adapter will 220V civilian AC, rectifier filter, and then converted to low-voltage 19V DC, for the notebook to provide power supply;
- Q: Siemens g120 inverter torque limit what is the meaning
- For example, you have 100kg of power, but you can send the power and you lift the weight of the object, if the object weight of 10kg, you can only use 10kg of power.
- Q: What is the output voltage of the laptop power adapter?
- Laptop power adapter output voltage, different brands may be different. Adapter output voltage is not a unified standard, different models are not the same notebook. The output voltage between 12V to 20V, 19V, 20V more.
