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 different brands of laptop power adapters be generic?
Power adapter can not use, the key to see two factors. First, the interface must first be the same interface or can not use. Second, the output current, the output current must be strictly consistent, otherwise it would be very dangerous, the laptop overload of the current is very fragile. The final output voltage I personally think can have a difference of type 5V. Because the battery on the voltage requirements up and down can have 5V floating. I have also used a high 5V adapter, has been no problem, but this is just my personal view. Strictly the same as the best. Oh, for reference only! Since you can plug in the normal use, indicating that the interface is consistent, and the output voltage and current are the same. Then I can responsibly tell you, rest assured to use it, there will be no problem.
Q: The laptop power adapter is hot
Notebook power adapter in the power after the use of hot is a normal phenomenon, do not worry, no danger, it will not explode. The length of this time does not matter, in the use of one or two hours will become very hot, but will always keep this temperature. And the notebook's power adapter shell are high temperature, will not burn. Notebook power adapter in addition to hot, you may hear the sound, the sound is not, very small. This sound is not a big problem, it is the power adapter power after the power filter sound, so plug in the plug after. Any power adapter basically has a sound. You can listen carefully, the surrounding environment is particularly quiet when you can hear. Power adapter is a transformer, inside the transformer coil in the AC will produce Zizi sound. Some power adapter use a long time will have this sound, but no big problem, you can continue to use. As long as the sound is not high outrageous do not control. Laptop power adapter hot and sound basic are considered normal, unless the temperature is too high or even damage to the shell or the sound is very obvious, this is a problem. The general does not affect the use of the adapter bad to buy a can. Notebooks have to protect the isolation circuit, do not worry about damage to the notebook.
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: The Schneider inverter reports the nlp command
Current transformers are also possible, or power supplies
Q: Do not the laptop directly connected to the power adapter?
3, the notebook internal circuit using low-voltage direct current work, if the direct use of 220V AC and its connection will burn the circuit in the low-voltage devices, which is absolutely prohibited, but also basic common sense. At the same time, its external power jack is also dedicated, and the AC outlet is different;
Q: On the laptop power adapter problem
Can be simply calculated; 19 * 4.74 = 90.06 90W 19 * 3.42 = 64.98 65W Obviously, the second is a virtual standard, can not be used It is not enough power, ranging from the adapter burned, while the motherboard is like other notebook hardware damage, unpredictable. The adapter is likely to burn after the high and low voltage to the notebook board burned the situation more common. My notebook is dell original 4.62A, when playing the game are very hot.
Q: The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
Motor speed formula: N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (s); F - power frequency (hz); P - pole pairs of motor rotating magnetic fields.
Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
4, high-speed motor: high-speed motor running process will produce a large number of harmonics, enhance the output current of the inverter, resulting in a lot of heat. Therefore, the inverter selection is also larger than the ordinary one gear. 5, explosion-proof motor: In some mines, oil extraction environment, the frequency conversion system is explosion-proof motor, the choice of inverter should use the explosion-proof function of the inverter, and the inverter placed in a safer place. 6, the degree of protection: for dust, wet applications, inverter selection should pay attention to its protection level. Or choose Ampang letter AMB inverter, the fan can also run in the water. 7, single-phase motor: When the scene using single-phase motor, the inverter useless. 8, variable pole motor: When the field using variable pole motor, the inverter selection should ensure that the maximum operating current should not exceed the rated current of the inverter
Q: Computer frequency changer to do cd frequency changer how points positive and negative
This inverter is 380V of the bar, the capacitor series is to increase the pressure, and then parallel to increase the capacity of the capacity of the capacitor and the inverter is proportional to the power, the greater the capacity of the capacitor capacity requirements are greater.
Q: How to make the motor speed (control speed), can not use frequency
Do not use the variable frequency motor with the speed motor
