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 to choose the right inverter?
- , fan, pump load This is the most suitable for use in frequency conversion speed of the scene environment, the inverter function technology is not too high requirements, the use of inverter energy saving effect is remarkable. For example: a large-scale heating equipment in a large-scale heating system, including blower, induced draft fan (centrifugal fan) inverter configuration configuration with the power of the P-type machine; water pump (centrifugal pump) inverter configuration configuration with the power of the P-type machine ; Conveyor pump frequency converter selection configuration with the power of G-type machine; belt machine (coal feeder) inverter configuration configuration to enlarge a file of the G-type machine; slag converter inverter configuration configuration to enlarge a file of the G-type machine; Crusher (coal crusher) inverter configuration configuration to enlarge a file or two stalls of the G-type machine.
- Q: Laptop power adapter current is not the same alternative?
- so the output voltage, the same output polarity, the output current of the adapter can be used in smaller power notebook, and small power adapter can not be used to give Powerful notebooks,
- Q: Notebook power adapter on how to look at power
- It should be noted that there are many in Japan to buy a notebook or over there in the parallel imports, input only support 110V in China is not used, because the Chinese standard is 220V. Now the subject is 90W 20V. Output voltage and power will be identified, such as the target for the 90W 20V, that output power is 90W, the output voltage is 20V. If only the output voltage and output current are identified,
- Q: Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power
- P = UI, that is, power = voltage × current. That is only the voltage of the motor will be faster, so the higher the speed the greater the power
- Q: What is the working principle of high voltage electrodes and frequency converters?
- High voltage inverter from high - low - high; low - high; high - high points. The following are the same as the " High-low-high-mode high-voltage inverter is the high-voltage power transformer with a step-down, with low-voltage inverter control, and then step up the transformer voltage to the voltage we use, the supply of high-voltage motor.
- Q: ASUS notebook power adapter can be universal? is it?
- Under normal circumstances, as long as other ASUS notebook power adapter voltage, current and interface with your notebook the same, you can use. Not ASUS adapter even if the voltage, the interface is the same is best not to use, easy to cause damage to the computer. I suggest you can call the ASUS national service hotline to see, consult the current market can support your laptop adapter model, and then to the computer store or online purchase. If you feel that my answer is satisfied, please adopt Wo take
- Q: Lenovo laptop power adapter side of the feet which is positive
- Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop.
- Q: Laptop power adapter problem
- Third, since the book is very old, the original factory may not have such a transformer spare parts, then a reasonable idea is to let this book off, rather than the provincial money to take their own little life joke, a notebook and then expensive It will not be more expensive than your life, the money is very unreasonable province. A notebook with a decade is also completely considered the best use of the matter, you are stingy stingy Ye Hao, there are emotional sustenance worth mentioning, it should be eliminated or out of it.
- Q: Is the motor having a variable frequency motor and a variable voltage motor?
- Motor with DC and AC motor, variable frequency motor and fixed frequency motor, string motor, that is, I have not heard of a transformer motor.
- Q: Please recommend a high performance laptop power adapter?
- Power adapter can recommend you what model you get what model ah he is a standard can not just recommend
