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: 380V motor addition to the inverter, but also how to change its speed?
- 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency
- Q: How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
- Yes, but it is not necessary, if it is old motor that is another matter, tell you that you can use, but can not be in the frequency conversion process for the pole, this will cause the inverter protection or failure
- Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- The frequency changer mainly consists of rectifying (alternating current direct current), filtering, re-rectifying (direct current alternating current), braking unit, driving unit, detecting unit micro-processing unit and so on. Motor asynchronous speed expression bit: N = 60 f (1-s) / p (1) Where n --- the speed of asynchronous motor; f --- the frequency of asynchronous motor; s --- motor slip; p --- motor pole pairs. From the formula (1) we can see that the output speed of the motor is related to the input power frequency, slip rate and the number of pole pairs of the motor. Therefore, the direct speed regulation mode of AC motor mainly has variable speed (adjustment P), rotor Resistance speed control or cascade speed or internal feedback motor (adjust s) and frequency control (adjust f) and so on. And we now use the most widely used is the frequency control, from the speed n is proportional to the frequency f, as long as the change in frequency f can change the motor speed, when the frequency f in the range of 0 ~ 50Hz, the motor speed adjustment range is very width. The inverter is to change the motor power frequency to achieve speed adjustment, is an ideal high efficiency, high performance speed control means.
- Q: Laptop power adapter aging
- First, the laptop power adapter is digital transformer, under normal circumstances either damaged, either available, no low voltage. Second, the notebook to play large games up to make the notebook because of poor heat dissipation caused by high temperature automatically shut down, not because of lack of power caused by automatic shutdown.
- Q: My laptop can not use the power adapter, and can only use the battery, how is it ah,
- 1, laptop power adapter can not be used, first check the power outlet, plug, cable has no virtual state, if you can tell the normal equipment damage. Should be repaired. 2, the laptop battery must be charged through the power adapter or directly for the computer power, the power adapter is not missing, if you have experience can turn on the power adapter to see if the fuse is broken, try to update the fuse can be restored. If the integrated circuit is damaged, only updated.
- 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.
- 3. Can try (the effect is not necessarily), for a large inverter and variable frequency motor, and the inverter installed braking unit, braking resistor.
- Q: Why the number of motor poles increased, the inverter capacity will increase
- The power of the three-phase motor is equal to the root number of 3 times the line current and the line voltage of the product again good with the power factor. Can also be 3 times the phase current and phase voltage of the good product and then good to power factor. The frequency converter should match the rated current of the motor, not the power of the motor.
- Q: Laptop power adapter output voltage is not the same as the current? What's the effect?
- I would like to elaborate on the basic principle of the large standard current power supply can replace the small standard current power supply. Some friends have misunderstood, that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, that is, the work of the books, when the books of high-load operation, the current larger, the books into the standby time, the current is smaller, in short, On the voltage divided by the equivalent resistance of the books. Large nominal current power supply has enough current margin, will not be replaced by a small standard current power supply after the overheating or output voltage is too low. On the contrary, with a small current power supply instead of high current power on the existence of the above risks. But some friends with 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply,
- Q: Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
- Can, but this is a test product, the application does not try!
- Q: Laptop power adapter is used to do what
- The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
