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:ASUS power adapter Acer can use it
- 2. Is the adapter's output current consistent with the notebook's requirements? (Or a little bit of the current is also not.)
- Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- Soft starters and frequency converters are two completely different uses of the product. The frequency converter is used for the need for speed control where the output not only changes the voltage but also changes the frequency; the soft starter is actually a voltage regulator for the motor to start when the output only changes the voltage and does not change the frequency. The frequency converter has all the soft starter functions, but its price is much more expensive than the soft starter, the structure is much more complex. Soft starter (soft starter) is a set of motor soft start, soft stop, light load energy saving and a variety of protection functions in one of the new motor control device, known as the Soft Starter abroad. The softener uses a three-phase anti-parallel thyristor as a voltage regulator, which connects it between the power supply and the motor stator. This circuit, such as three-phase full-bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor gradually increases, the motor gradually accelerates until the thyristor is fully conductive, the motor works at the mechanical characteristics of the rated voltage, smooth start, reduce the starting current and avoid starting the overcurrent trip. When the motor reaches the rated speed, the start-up process ends, the soft starter automatically uses the bypass contactor to replace the completed thyristor, providing the rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor and prolong the service life of the soft starter , To improve its efficiency, but also to avoid the harmonic pollution to the grid. Soft starter also provides soft stop function, soft stop and soft start the process of reverse, the voltage gradually reduced, the number of revolutions gradually reduced to zero, to avoid free-wheeling caused by the impact of torque. How the frequency converter works
- Q:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
- The number of poles of the motor and the inverter is not very different, the difference is the motor speed is different
- Q:Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
- n the motor pole, an Antarctic (S pole), an Arctic (N pole), calculate a pair of poles, the number of pole pairs is how many such "pairs" (S pole + N pole). 2 pole motor --- pole pairs 1 = P = 1,4 pole motor --- pole pairs 2 = P = 2, and so on.
- Q:How to choose the right inverter?
- 1, constant power load During the operation of the load device, the power remains constant. Such as machine tools, cutting machines, paper machines and so on. For example: a marble cutting machine frequency conversion system, is a constant power load, load inertia, inverter selection configuration A power with the G-type machine, plus the braking unit and braking resistor.
- Q:Is the motor having a variable frequency motor and a variable voltage motor?
- Have. 2, variable speed control; 3, electromagnetic speed; 4, variable speed control; 5, variable resistance speed control. Household fans are variable speed control. In addition, the DC motor can also use variable voltage to speed.
- Q:Laptop warranty period is not over, the power adapter is broken, repair money?
- Warranty warranty, what is the warranty, that is broken, to ensure that free repair to you, repair bad on the new Dealers are not responsible for sale, need to go to a dedicated service network. Warranty period, should not be money. If the money, the first 800 to ask to say clearly
- Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
- Depending on your question may be the problem that the laptop's internal lines may be short-circuited 1, you can go to the video online to find the same type of machine disassemble video and then repair their own 2, get to the maintenance of the place to get on nothing
- Q:Inverter problem
- A: The inverter output 4 ~ 20mA (0 ~ 20mA), the analog signal can be directly connected to the measuring instrument, the daily design, installation, application are so, as long as the selection is correct, there will be no problem.
- Q:How does the variable frequency motor output torque at very low frequencies?
- 1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
