General Introduction
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, medium voltage variable frequency drive has the following functions :
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

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.
Medium voltage variable frequency drive has the following features:
- 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 to choose the right inverter?
- 2, constant torque load Constant torque load equipment requires low frequency inverter torque, dynamic response speed. Inverter 0HZ vector state, to 150% of the torque, to meet the needs of various conditions. For example: a dredger owner bucket inverter system, is a constant torque load, dual motor, and the load overload time is long, so the inverter configuration configuration to enlarge the two models of the G-type machine, while the power supply for the device Machine power supply, the inverter must be configured to input AC reactor.
- Q: A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
- If it is normal V / F control, then do not need to modify too many parameters to limit the frequency limit of 50%
- Q: How do I protect the inverter when the three-phase two-pole motor is running?
- A: At this time to put the heart in the stomach, wait and see the change, what do not move (to prevent the accident to expand), until the motor stops, and then confirm, what kind of protection: alarm (alarm automatically after the release) or failure , Such as: over-voltage, overload, over-temperature, etc., and then the right medicine; inverter in the run which is not allowed, forced parking stop. Otherwise it will cause serious damage to the inverter.
- Q: Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power
- The original you are the ordinary motor ah, this ordinary motor can not afford too high frequency. Often at high frequencies or low frequency work will burn the motor. The higher the speed, the current will increase, the lower the speed, the current will be reduced. Its power is not much change. You still with a special frequency control motor it. Frequency conversion motor is a special design, the use of frequency converter for the drive power, the motor and inverter electromechanical integrated frequency control system, so as to achieve low frequency constant torque operation and high frequency constant torque operation. This motor has good speed performance and significant energy saving effect
- Q: What is the laptop adapter
- 3, classification: according to the use of points (AC, such as home, office use AC are called AC; DC, such as the car, the aircraft are used DC are called DC); by the output voltage current (12V series, ASUS more commonly used, such as ASUS 12V3A; 15V series, TOSHIBA more commonly used, such as TOSHIBA 15V3A, 15V4A, 15V5A; 16V series, SONY, IBM more commonly used, such as SONY 16V4A, IBM 16V4.5A; Series, HP, such as HP 18.5V3.5A; 19V series, such as ACER 19V3.42A, TOSHIBA 19V3.42A; 19.5V series, such as DELL 19.5V3.34A, SONY 19.5V4.1A; 20V series, such as DELL 203.5A , LENOVO 20V3.25A; 24V series, such as APPLE 24V1.875A; 9.5V-24V series, such as Acharger ALS-185A35C).
- Q: Yaskawa inverter reported base blockade what is the reason?
- For example, when you stop the inverter, there will be a signal to the inverter, and then the inverter will base block, cut off the output, the motor will no longer work; when you need the inverter work, There is a signal to the inverter, the inverter to cancel the base blockade, it is normal work,
- Q: Laptop power adapter problem
- Second, the transformer This thing is not standardized production, the result is that even if the parameters of the same, the transformer to get another of this may not be compatible with the use of the explosion with the use of the cup like the situation, so we generally Stressed the original transformer.
- Q: Do not the laptop directly connected to the power adapter?
- 4, but you can use the external 14 ~ 20V battery, connected to the matching power plug for the notebook power supply, the effect and the use of the same power adapter.
- Q: Will the laptop's power adapter is not the original good?
- Theoretically can be inserted into the use and will not have any obvious damage to the machine But it is best to buy the number of volt and your original consistent Original also has original benefits According to some "professional" sources claim that no original touchpad will have a slight jitter, I was not found
- Q: 400w 6-pole motor should be equipped with much of the inverter?
- Under normal circumstances, the market are sold on the inverter are based on the common 4-pole motor matching, when to match the 6-pole motor, the inverter to a large power level, which is 400W of the first-class power 0.75KW, and so on
