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: Laptop power adapter current is not the same alternative?
- so the output voltage, the same output polarity, the output current of the adapter can be used in smaller power notebook, and small power adapter can not be used to give Powerful notebooks,
- Q: Does the teacher know the working principle of the inverter?
- Very basic questions, the principle of fine you go online search, everywhere, I do not like to copy someone else, I simply tell you about: Voltage type inverter Three-phase alternating current to the rectifier module, converted into DC, filter stored in the electrolytic capacitor, IGBT + and - from the electrolytic capacitor to take energy, by the DSP (or other controller) output PWM pulse control IGBT turn on and off, So the output AC, the AC and input AC waveform is very different, so that the inverter is also a source of interference. Current filter in the middle of the filter is the inductor non-capacitance, we are more commonly used on the market and the economic converter are mostly voltage-type inverter.
- 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: My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
- Motor current when the current 10A this has no effect on you, the rated current is 31.4A, your inverter is selected how many W, is the fan pump type or universal? Now the motor operating current reached 34-35A, more than the rated current, then the motor may have two problems, one is the motor leakage powerful, and in a motor is overload, resulting in increased current
- Q: Notebook plug in the power adapter lights, but can not open the machine
- Put the board under the re-installed, try and then boot. Asked: This is the case of removal, with the battery can boot answer: Then put the battery on the computer, and then use the power splitter to see if you can. If not I do not know, is the computer question to ask: This can be
- Q: Yaskawa inverter reported base blockade what is the reason?
- Yasukawa compared garbage on the signal board on the small line of poor oxidation, and get like, this is a weak signal, and safety relays connected, do not use high-grade security circuit with a small line short, Yasukawa A 1000 factory is short for a long time after the oxidation of the base blockade
- Q: Laptop power supply 20V 3.5A can use 20V 4.5A power adapter Mody, what impact?
- can. For a constant voltage power adapter, the following requirements can be replaced: The replacement of the new power adapter output voltage is the same as or similar to the output voltage of the original power adapter. Replacement of the new power adapter maximum output current is not less than the original power adapter maximum output current. Replacement of the new power adapter with the original power adapter interface definition and shape the same. Replacement of the new power adapter Other non-major electrical performance indicators, not less than the original power adapter of the corresponding indicators. Notebook original power adapter nominal rated current of 3.5A, indicating that the laptop itself does not exceed the input current of 3.5A, for the rated current of 4.5A power adapter, the drive is no problem in this load.
- Q: Is the laptop power adapter AC and DC?
- In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, if the nameplate indicates that the input voltage is AC 110V, then in China's 220V mains voltage Plug it will burn.
- Q: The laptop's power adapter is broken how much it costs
- Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,
- Q: Inverter principle eff23
- Low-voltage general-purpose inverter output voltage of 380 ~ 650V, the output power of 0.75 ~ 400kW, the operating frequency of 0 ~ 400Hz, its main circuit are used to pay straight to pay the circuit. Its control has gone through the following four generations. 1U / f = C sine pulse width modulation (SPWM) control mode is characterized by simple control circuit structure, low cost, mechanical properties of hardness is better, to meet the general requirements of the smooth transmission speed, has been in various fields in the industry Widely used. However, this control mode at low frequencies, due to the lower output voltage, the torque by the stator voltage drop is more significant, so that the maximum output torque reduction.
