 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:A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply
3. Take a doorway as an example: choose DN50, N = 7.5Kw enough. About 50 cubic meters / H.
Q:380V motor addition to the inverter, but also how to change its speed?
Use the star connection to reduce the speed by changing the torque
Q:The laptop's power adapter is broken how much it costs
Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,
Q:How to view your own laptop power adapter is how much tile?
1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.
Q:What are the AC motor speed control methods? What are the characteristics of each
Pressure control speed, limited speed range is limited use of variable pole speed, change the motor internal wiring speed, speed is a very speed according to the motor factory set to brand speed to speed control, change the motor input Frequency to speed, are stepless speed is now more popular
Q:How to view the parameters of the notebook power adapter on your computer
The correct way to use a laptop power adapter 1. Try to avoid use in outdoor or harsh environments to prevent the adapter from being exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter
Q:Jd1a-40 motor speed controller and how to connect the motor
Speed ​​control motor wiring method: 3.4.5 is the terminal of the tachogenerator (U / V / W) from the right-to-left order of 1.2 for the excitation coil (F1 / F2) terminal, from the extended end of the speed motor (electromagnetic clutch) Master 7 plugs on the air plugs (governor): terminal 1.2 for the 220v input, 3.4 on the speed of the motor on the excitation coil, 5.6.7 speed motor on the tachogenerator. Motor speed control method: The speed regulating motor is to change the speed of the motor by using the series, voltage, current, frequency and so on of the motor to make the thyristor voltage regulation method the best.
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
Or the star of the three-phase motor to the corner, so that after the rectifier inverter into a 220-volt three-phase AC ...
Q:5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?
Because the frequency converter can reach 60 Hz frequency, while the three-phase power supply is the standard 50 Hz. So the inverter can make the motor speed faster than the rated 1500 rpm. The fastest up to about 1800 turn.
Q:The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, but is being used in the motor replacement, you need to change the frequency conversion.
