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: Inverter alarm a043, how is it
- When there is a signal failure, if necessary, use DTI Board, if necessary, change P215 In addition, for the synchronous motor (P095 = 12): the inverter is released until the motor is at rest
- Q: Can the laptop power adapter be generic?
- Output voltage, current, interface can be used as well.
- Q: What is the working principle of high voltage electrodes and frequency converters?
- High-voltage inverter is the input power supply voltage above 3KV high-power inverter, the main voltage levels are 3000V, 3300V, 6000V, 6600V, 10000V and other voltage levels of high-voltage high-power inverter High voltage inverter from high - low - high; low - high; high - high points.
- Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.
- Q: Laptop power adapter how to detect?
- After opening to see what is burned, Estimated to be insurance and the like
- Q: Do you need to rectify before switching?
- There are two ways to convert frequency, that is, cross and cross the intersection, the latter need a direct current, need no rectification, depending on your DC situation.
- Q: What is the difference between the collector and the emitter mode?
- This physical structure is intended to facilitate the need for positive enlargement.
- Q: The laptop's power adapter is too hot to do
- The original adapter heat should be no problem, the fan mouth is very hot, the weather may be more and more hot it!
- 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: What is the output voltage of the laptop power adapter?
- Generally have 19V of the common friends, I was 19V
