Working Principle
WLD-HVF series medium voltage inverter adopts Power Units in series and overlapping technology to obtain MV directly by means of overlap wave. Low voltage power unit is an actually improved motor variable frequency inverter, which takes full advantage of mature technology. WLD-HVF belongs to High-high voltage source inverter, the customer can connect high voltage (3/6/10KV) directly to WLD-HVF, then WLD-HVF output high voltage (3/6/10KV) correspondingly. WLD-HVF consists of phase-shifting transformer, power unit cabinet and controller, for example:
6KV Series: Consisting of 15 AC power units with 690V. Every 5 power units are connected in series to form one phase (phase voltage 3450V), 3-phase Y-type connection, so the Line voltage can reach to 6KV.
Energy Saving Fields
Power Generation: Induced draft fan, forced draft fan, condensate pump, feed pump, primary air fan, secondary air fan, booster fan, circulating pump, mill fan, slurry pump etc
Cement: draft fan, high-temperature fan, air blower, dust collection fan, grinding machine etc.
Metallurgy: blast furnace blower, slurry pump, feed water pump, dust fan, compressor etc.
Petroleum&Chemical: Water injection pump, crude oil pump, Compressor, fan, circulation pump, etc
Urban water supply: Water delivery pump, water intake pump, water supply pump, sewage treatment industry, self-fractionating pump etc
Minerals & Mining: Mud pump, ventilation fan, belt conveyor, slurry pump etc
Others: Loads such as fan, pump and compressor in pharmaceutical, paper making and wind tunnel test
Patented pre-charge technology
The pre-charging function can effectively control the charging speed of the capacitors, and thus charging shock can be prevented. Together with IGBT intelligent driving technology, the innovations can double the lifetime of the capacitors, from 5 years to 10 years for instance. The maintenance cost can be lowered significantly.
Patented automatic recovery technology
With real-time monitoring, the VFD system can identify the causes of power cell bypass, and automatically restarts once it detects the problems are fixed. It ensures equipment to operate continuously and stably when the bus power supply has instantaneous failure.
Patentedventilation and heat dispersion method
Our VFD’s ventilation system is centralized and vertical. It has significant advantage over the distribution type in terms of temperature field control, air flow distribution, and wind speed uniformity. Since the capacitor units are located at the ventilation ducts, it is estimated that the lifetime of capacitor can be doubled, and thus the overall system service time is prolonged with this cooling mechanism.
- Q: How does the laptop's power adapter open
- Control Panel - System - Hardware - Device Manager - Network Adapter, right click, and the menu appears. If it is infinite, then first follow the above argument to see if it can be enabled.
- Q: Pump frequency converter instantaneous restart and restart the problem
- Speed tracking start. The specific to ask you to drive the inverter that guy. He earned your money there is a need for technical support
- Q: Is the speed of the motor controlled?
- Armature for the cast steel made of cylindrical structure, which is connected with the squirrel cage induction motor shaft, commonly known as active part; Pole made of claw-shaped structure, mounted on the load shaft, commonly known as the moving part. The active and slave parts are mechanically free of any contact.
- Q: Asus notebook power adapter how to open
- if the power adapter is broken directly to the computer with a city on the line can not spend a few money back you can burn the computer is bigger to go to the computer The city took to repair and no one to repair to buy a very low price
- Q: Laptop computer about electricity no electricity, is the power adapter problem?
- This situation is definitely not about what power off, if it is really about electricity no electricity, then your laptop is a one-time shutdown, rather than the screen flashing. I think this situation is more like a laptop screen lamp problem. Is unlikely to be a power problem. The screen flashes from the surface that there may be enough current. If the adapter can not provide enough current for the notebook, then the notebook will be over-current protection, which automatically shut down. You can find an adapter with the same output voltage as your adapter, the output power is greater than or equal to your adapter other adapter, if the situation remains the same, then it is certainly the problem of the lamp. But the inferred will not be a power problem.
- Q: Servo control system can give the inverter signal,
- Servo motor driver can give the inverter signal, with analog output to control,
- Q: Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
- 7 seconds more than a change, too often. It is estimated that the inverter will not work. Suggest:
- Q: The laptop's power adapter is broken how much it costs
- Hello, this is not very expensive Generally in 80 or so, you can go to the Internet to see the model, and then to the store to buy the price on it.
- Q: What is the frequency converter used to do, why some motor with the inverter?
- Speed control, there are speed requirements of the place are in the inverter
- 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;
