"AC Motor Drive MV Variable Frequency Drive"

 

 

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:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is no load, the demolition of the gearbox is the same can be run.
Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
Is the inverter must be. Do not know you are also a generic vector. If it is common to directly on the instructions on the motor logarithmic change 6 pole, turn the number changed to 980 on the line. Vector, then change the number of 980 and then learn from the line on the line.
Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
Communication can reach a longer and more stable, generally better of the city 485
Q:There is no inverter comes with simple PLC programming function
The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.
Q:On the laptop power adapter problem
Notebook power adapter matching the principle of the principle is: the input voltage to meet the requirements of the domestic exchange is 220V; output voltage and the original with the same output current must be greater than or equal to the original adapter output current, your future output current is less than the original will appear Power from time to time unexpected shutdown caused by increased data loss, the battery charge is not easy to rush to cause the battery aging process, the other adapter long-term work will increase the heat caused by increased safety risks.
Q:In the official website to buy ThinkPad notebook, to the power adapter?
Hello, generally there will be a power adapter with Kazakhstan, unless there is a special note bare metal
Q:The laptop power adapter is burned
You want to say that the power line or the two brands of power adapter? If only refers to the power cord, then you can rest assured that the world's power lines can be used, this line is an international standard, regardless of you and me, TV CD player line
Q:How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
Although the waste, but can be used, we use the frequency band with two-speed motor when the output is connected to the fast three terminals, you can refer to the next
Q:Laptop power adapter problem
First, that is called the transformer, not called the charger, not with you bite the word, but you according to the charger to Taobao search, basically one hundred percent are not found.
Q:380V 2 pole motor can use the inverter?
Special attention, variable frequency motor with the ordinary different, easy winding film damage
We are a professional inverter manufacturer integrating R&D, production and sales. With an experienced R&D and production team and sophisticated production lines, our company has become a domestic first-class inverter manufacturer by virtue of advanced technology, excellent quality, scientific management and perfect service
