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: The relationship between the power supply of the notebook and the battery
- 2, when the laptop turns on the power adapter, and the battery power is low, the charging circuit detects the battery power is lower than the set value, the power adapter will side of the host power supply, while the battery charge. After the charge is restored, it is restored to the power supply state directly from the adapter. Therefore, the relationship between the power supply of the notebook and the battery is that the battery is charged by the power adapter when the battery level is below the set value.
- Q: How is the notebook with a power adapter?
- Clear use: Home use and office with the laptop power adapter to buy a home (AC), the car with the laptop power adapter, to buy a car, you want to use the aircraft on the basis of the car with a The aircraft head on it. Home, car, plane, want to take into account, to buy a two-in-one, or three in one. But if you do not want a few bags of computer weight, you can put a home, put a car, the office put a, so you can not bring to bring, plug to plug, more convenient, you can also give people around
- Q: Will the 75KW4 pole motor can be used to increase the speed of the inverter?
- Can not, only slow down, on our national grid, 50HZ is the largest. At least with the inverter can not be achieved.
- 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 is the characteristic of the variable pole speed method?
- Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: The process of the slip loss back to the grid or production machinery, the higher efficiency; device capacity and speed range is proportional to the investment province, for speed range in the rated speed of 70% -90% of the production machinery; Device failure can be switched to full speed operation, to avoid shutdown; thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders. Fourth, winding motor rotor series resistance speed control method Winding asynchronous motor rotor series into the additional resistance, so that the motor slip increase, the motor running at a lower speed. The greater the resistance of the series, the lower the motor speed. This method is simple and easy to control, but the slip power is consumed in the form of heat. Is a level of speed, mechanical characteristics of soft.
- Q: Who knows how the frequency converter works
- 2. flat wave circuit In addition, the ripple current generated by the inverter also changes the DC voltage. In order to suppress the voltage fluctuation, the inductor and the capacitor absorb the pulsating voltage (current). In general, the DC voltage of the rectifier is rectified and the DC voltage is rectified. General inverter power supply of the DC part of the main circuit in terms of margin, so eliminating the need for a simple capacitor filter smoothing circuit.
- Q: Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
- The existing Taian inverter 380V3.7KW can bring 4.0KW 2 pole motor, 18000 to 300HZ can also see how you load, It is best to check your wiring tightness and whether the load is stuck. It is recommended to use the N310-4005-S3 this model, such as with the E510-405-H3 better.
- Q: 400w 6-pole motor should be equipped with much of the inverter?
- Under normal circumstances, the market are sold on the inverter are based on the common 4-pole motor matching, when to match the 6-pole motor, the inverter to a large power level, which is 400W of the first-class power 0.75KW, and so on
- Q: How to learn the inverter debugging and design parameters
- You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.
- Q: Please recommend a high performance laptop power adapter?
- See what model you notebook ah, according to your power adapter voltage, rated current to match.
