General Introduction


From the above, different voltage output, the quantity of power units is different, but the working theory is exactly identical. All power units receive the indicator from same central process controller. There is a phase difference in secondary windings of transformer which provide energy for power unit, in this way, most of the harmonics current caused by independent power unit will be eliminated, so the primary winding current is approximately sine wave, the harmonics current flowing into power grid are so few, even under the rated load, the harmonics contents is lower of 3%.

 

The power unit is AC-DC-AC structure, equivalent to a low-voltage power source inverter of 3-phase input single-phase output. The rectifier side is diode three-phase full bridge circuit and the IGBT inverter bridge can be controlled through sine PWM mode to output single-phase AC. All power units are fully identical in structure and electrical performance, very easy for maintenance and replacement.


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 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.

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: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 power adapter bad what is the phenomenon?
Either the power is bad or the machine on the power supply module is bad to repair service
Q:Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,
The frequency is too low or the brake gap is small
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
1. submersible pumps are generally the problem, far away from the reflection voltage, the pump insulation breakdown, in particular, to better pump. 2. Distance away, the inverter and pump connection thicker. 3. Then on the output filter.
Q:The parameters of the inverter is 4, 6 motor can be used
Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment.
Q:What is the motor series parameter setting of the inverter? If it is with the spindle,
Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning
Q:How to disassemble the notebook power adapter
HP laptop power adapter for the whole design of small sealed, you can follow the following steps to dismantle: 1, laptop power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence Cracked. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open.
Q:Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole
Running in the low frequency or other? Load it, the motor cooling mode is built-in fan or forced air cooling? Pump motor connection has not checked about, such as triangular error into a star and the like, hoping to have you help
Q:The laptop's power adapter can be used on a desktop computer
First of all, the desktop is the kind of power, is ups uninterruptible power supply. But relatively large, not directly inside the chassis. In addition, the storage capacity is limited.
Q:Laptop power supply 20V 3.5A can use 20V 4.5A power adapter Mody, what impact?
It's ok. As long as the voltage is appropriate on the line. Current value refers to the maximum current that can be output. How much depends on your computer. Or, with a big no harm, can only be better, if you can use a small, but a little longer charging time.
