What are the energy saving and power saving measures of enterprises?

For production-oriented enterprises with high energy consumption, electric energy is the main resource of the enterprise, how to do a good job in energy management! First of all, it is necessary to find out the waste of electricity in the enterprise, and to do a good job in the measurement and statistics of electric energy management

It is not possible to grasp the current status of electricity consumption, 2It is impossible to quantify the energy-saving indicators of the enterprise, the aging of the equipment, 3Need to update energy-saving equipment, equipment utilization rate is not high, power quality is not good; In view of this kind of situation, the enterprise should consider the establishment of a set of power management and control system, at present, most of the enterprises are managed through human experience, energy saving indicators also rely on experience, according to the current situation, the enterprise power management system is the necessary management program for each enterprise in the future, is to ensure the safe operation of the substation and distribution system at the same time, the collection of scientific energy consumption data to provide evidence for the energy saving indicators of the enterprise.

Therefore, energy management is the top priority of enterprises!

How? Personal opinion is for reference only: you need to analyze where electricity is used and where it is mainly used. If 80% of the electricity is used in the motor, then your main direction is to understand the power saver in the motor.

Saving electricity means saving electricity, and saving electricity is not not using electricity, but using electricity scientifically.

In China, the power quality is poor, transients, surges, spike pulses, harmonics, etc. flood the entire power grid, coupled with the use of nonlinear loads at the user end, power-saving vector diagram impact loads, fluctuating loads, and asymmetric loads The main reason for low power quality is the reduction of power factor, the reduction of power energy efficiency on the entire user side, and the endless potential safety hazards.

The main power-saving technologies include surge, transient suppression, harmonic cancellation, reactive power compensation, and system impedance balance. Power load side: soft start technology, frequency conversion technology, system power-saving technology.

I am a professional power-saving device, you can consult if you have any questions.

The measures to save electricity by enterprises are as follows:

2. Computers that are idle or not used within two hours should be shut down in time to ensure that people take the organ and the organ is powered off;

3. The computer needs to be maintained and cleaned frequently, pay attention to dust and moisture, and reduce power consumption;

4. Turn off water dispensers, computers, printers and other electrical equipment 20 minutes before getting off work, and unplug and disconnect the power supply;

5. The use of air conditioning strictly implements the 26 degree standard, and the air conditioner must be turned off after leaving for more than half an hour to reduce energy consumption;

6. It is forbidden to use office computers for entertainment activities.

There are the following points in terms of energy conservation in enterprises:

1. The first draft of the document should be drafted as much as possible, the line spacing should be reduced, and the small font should be used to print to save paper, ink and electricity;

2. Double-sided copy and printing paper should be used for copying and printing paper, and the copy paper after single-sided use can be photocopied or cut into note paper or scratch paper on the blank side;

3. Reuse the reusable briefcase;

4. Try to use network sharing, transfer and read documents to each other on sharing, or use e-mail instead of paper documents;

Through strict rules and regulations, the use of unreasonable energy-using equipment is eliminated. Through on-site inspections, energy waste is stopped.

8. Energy saving and consumption reduction - first of all, we must first start from the large energy consumers, due to the shortage of energy, with the further development of energy conservation work. A variety of new, energy-saving advanced furnace types are becoming more and more perfect, and the use of new refractory fibers and other high-quality insulation materials makes the heat dissipation loss of the furnace significantly reduced. The use of advanced combustion devices strengthens combustion, reduces the amount of incomplete combustion, and the air-fuel ratio tends to be reasonable.

However, the technology to reduce exhaust heat loss and flue gas waste heat is still not progressing rapidly. In order to further improve the thermal efficiency of the kiln and achieve the purpose of energy saving and consumption reduction, flue gas waste heat is also an important way to save energy.
