Energy-saving Solutions for Enterprise
1、Program Overview
◆Saving energy achieves 10% -70%
◆The enterprises do not need to pay for expense of equipment manufacture and installation.
◆Enterprises only need to pay the saving electricity expense to our company according to the actual quantity of energy saving after the equipments put into operation.
◆According thousands of the projects’ implementation experiences, such projects recover the investments in three or four years. (Equipment service life is 15 years)。
◆Our company will no longer charge the saving electricity expense after recovering the investment.
The significance of the program:
1）、Concentrate on solving problems of energy conservation, make enterprises’ energy-saving work reach new level and take their social responsibility。
2) 、Avoid the enterprises reactive power fine of low power factor caused by electric energy using (according to Ministry of Electric Power and Water Resources, State Price Control Bureau establish the " measures of power factor adjustment expense ").
3）、Avoid the high-energy consumption enterprises are implemented differential prices because of the changes of national power regulation.
4）、For the standard-conforming large-scale (saved energy equal 10 thousand tons standard coal or more) energy-saving technological transformation projects, China will reward the enterprises for energy saving which based on the "Financial Incentives Interim Measure for Energy-saving Technological Transformations" established by Ministry of Finance, the National Development and Reform Commission.( Amount of 200 yuan / ton of standard coal).
5）、Equipments recovery period is generally 3-4 years, each period payment equal to the amount of current energy-saving benefits, and equipments service life are 15 years, so enterprises will gain huge energy-saving benefits.

- Q:Can the HP laptop's power adapter be universal?
- Hello! Thank you for choosing HP products. Based on your description, we recommend that you refer to the following information: Notebook power adapter is generally depends on the adapter interface, input and output of the parameters are consistent, it is recommended that you see the parameters on the power adapter to see if the same, if the agreement then the two machines can be common adapter.
- Q:Who knows how the inverter is calculated?
- There is no pole in the inverter, the electrode can be polarized, the greater the number of poles of the motor the slower the speed, please refer to.
- Q:ABB frequency converter and the difference between domestic frequency converter
- The objective lens is equivalent to the lens of the projector, the object is inverted through the objective lens, magnified real image. Eyepiece is equivalent to the ordinary magnifying glass, the real image through the eyepiece into a positive, magnified virtual image.
- 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:There is no inverter comes with simple PLC programming function
- The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.
- Q:What is the difference between the collector and the emitter mode?
- The emitter is very high, the base is mixed and the collector is the lowest
- Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
- Electronic governor is for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the power supply power for the output does not change, so this speed is not an energy Type of speed control methods, such as home for the use of fans and the like. Inverter speed is the original direct input three-phase asynchronous motor power first access to the inverter, in the inverter through the PWM and other electronic converter technology to rectify the frequency AC, inverter, become a frequency controllable AC In the input to the motor, in the motor running through the V / F control, output torque control, vector control and other control methods to adjust the frequency, change the loop current, to achieve energy-saving operation, especially in the light load energy efficiency is obvious, An energy-saving products that have been widely promoted and applied
- Q:Who knows how the frequency converter works
- 4 inverter circuit Inverter circuit In contrast to the rectifier circuit, the inverter circuit converts the DC voltage into the AC voltage of the desired frequency, and turns on and off the power switch device of the upper bridge and the lower bridge at the determined time. Which can be in the output U, V, W three phase phase difference between the 120 ° electrical angle of the three-phase AC voltage.
- Q:How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
- Although the waste, but can be used, we use the frequency band with two-speed motor when the output is connected to the fast three terminals, you can refer to the next
- Q:What is the application of variable frequency speed control?
- In the second half of the 20th century, the power electronic devices from the SCR (thyristor), GTO (gate can be turned off thyristor), BJT (bipolar power transistor), MOSFET (metal oxide field effect transistor), SIT (electrostatic induction transistor ), SIT (Electrostatic Inductive Thyristor), MGT (MOS Control Transistor), MCT (MOS Control Gate) to today's IGBT (Insulated Gate Bipolar Transistor), HVIGBT (High Voltage Insulated Gate Bipolar Thyristor), Device To promote the continuous development of power conversion technology. Since the 1970s, pulse width modulation variable frequency (PWM-VVVF) speed control research has aroused people's attention. In the 1980s, the PWM model optimization problem, which was the core of the frequency conversion technology, attracted people's interest and made many optimization modes, in which the saddle-wave PWM mode was the best. The 20th century, the late half of the 1980s, the United States, Japan, Germany, Britain and other developed countries VVVF inverter has been put into the market and widely used.
