What are the measures for electrical energy conservation, and what are the methods and measures for

1) Reduce the active power loss of the transformer. The transformer should be energy-saving to reduce the eddy current loss and leakage magnetic loss of the core.

At the same time, the load rate of the transformer should be increased to 75% 85%, reduce the line loss of the transformer, and the transformer with large capacity should also be selected, and the number of transformers should be reduced as much as possible, so that the transformer can operate economically.

2) Reduce energy loss on power supply and distribution lines. Conductivity should be chosen.

The smaller copper core material is used as the wire, which reduces the length of the wire and increases the cross-sectional area of the wire.

3) Improve the power factor of the system.

Higher-order harmonic coefficients of less than 15% are used.

Measures such as electronic ballasts can increase the natural power factor to 0 85~0.95, which can reduce the advanced reactive power transmitted by the high and low voltage lines of the system.

There are also capacitor compensation, reactive power compensation device installation and local compensation, etc. As long as the three parts of reducing natural reactive power, reactive power compensation and the installation site of the compensation device are dealt with, a reasonable selection of reactive power compensation mode can be achieved to achieve the purpose of energy saving.

4) Energy saving in the lighting section. Due to the large amount of illumination and the wide area, there is great potential for energy saving, including the use of high-efficiency light sources; The building is close to the room.

The outer part increases the area of doors and windows, and uses glass doors and windows with good light transmittance to make full use of natural light; All lighting that can use natural light adopts automatic adjustment of lighting according to the degree standard; Variable illuminance lighting can be automatically controlled by components and slices.

5) Energy saving of the motor during operation. The main thing is to reduce the light load and no-load operation of the motor. Frequency conversion governor can be adopted, so that it automatically adjusts the speed when the load drops, so as to adapt to the change of load, improve the efficiency of the motor at light load, and achieve the purpose of energy saving.

Another way to save energy is to use a soft starter, which gradually adjusts the thyristor according to the start-up time.

to control the change in voltage. Such as domestic water pumps, elevators and other equipment.

6) Application of high-efficiency and energy-saving electric heating equipment. Promote the use of regenerative electric water heaters and electric boilers, and cut peaks and valleys.

Make the grid and generate electricity.

The operation of the machine is more stable, economical and long-lasting.

7) Integrate the traditional power supply and distribution system, air conditioning and ventilation system, electric lighting system, etc. into the intelligent control network for computer management.

Reason. Advocate household ** air conditioning.

The energy-saving controller manages the cooling and heating equipment on a unified platform to reduce unnecessary energy waste. Especially in the southern part of our country.

It is necessary to open the air conditioner to cool or heat the air all year round, which is not only a large energy consumer, but also a large user with energy saving potential.

Generally, it is the power frequency change frequency.

1) Household power saving: turn off the lights at will, turn off the power in time after using electrical appliances, turn down the volume of TV, stereo, etc., set the temperature of the air conditioner at 26 degrees Celsius and above in summer, etc.;

2) Office power saving: In terms of lighting electricity, natural light can be used to turn on electrical appliances as little as possible. When you need to turn on the lights, try to avoid turning on all the lamps and keep enough lighting brightness.

Turn off the lights, turn off the air conditioner, computer and other electrical equipment during lunch break and after work. When leaving the office for a long time, the main switch of low-voltage power supply should be turned off;

3) Enterprise energy saving: reduce transformer capacity, make full use of the peak-to-valley electricity price difference, strengthen reactive power compensation, and adopt other energy-saving technologies.

We hope you find ours helpful.

1) Formulate reasonable construction energy consumption indicators and improve construction energy utilization. 2) Give priority to the use of energy-saving, efficient and environmentally friendly construction equipment and tools recommended by the state and the industry, such as energy-saving construction equipment with frequency conversion technology. 3) The construction site sets the power control indicators of production, living, office and construction equipment, regularly carries out measurement, accounting, comparative analysis, and preventive and corrective measures.

4) In the construction organization design, the construction sequence and working face are reasonably arranged to reduce the number of tools in the operation area, and the adjacent operation area makes full use of the common machine resources. When arranging construction processes, priority should be given to construction processes that consume electricity or other use less energy. Avoid the phenomenon that the rated power of the equipment is much higher than the used power or overload the equipment.

5) Make full use of renewable energy sources such as solar energy and geothermal energy according to local climate and natural resource conditions.

There are many ways to save energy, such as:

1.Turn off the lights in time when you leave the room.

2.When traveling, try to use public transportation to get around.

There are many energy-saving methods, common ones, and the effects are more obvious

1. Adopt thermal insulation materials. 36% of the world's energy is spent heating and cooling homes. "Zero Energy Residential" model homes built in Switzerland and Germany.

It shows that the use of new materials and new methods for heating and cooling is incalculable.

2. Use energy-saving lamps.

20% of the world's electricity is consumed on lighting, and 40% of that electricity is old-fashioned incandescent lamps.

The bubble is consumed. Energy-efficient fluorescent lamps not only save 75 to 80 percent less electricity than incandescent lamps but also last up to 10 times longer than incandescent lamps with the same amount of luminous light.

3. Improve household heat exchangers. Water heaters, heaters, and air conditioners are actually very inefficient, and only a fraction of the energy consumed by these heat exchangers is actually used to regulate the temperature. Heat pumps will change that.

Heat pumps use heat from the outside air or geothermal heat to heat or cool a building with little to no traditional energy consumption.

4. Transform the energy consumption equipment of the factory. About 1 3 percent of the world's energy is consumed by the industrial sector, which has great potential for energy saving. For example, since the 80s of the last century, Japan's Mitsubishi Heavy Industries Company has used the waste heat of steelmaking furnaces to generate electricity, saving more than 70% of energy.

5. Drive environmentally friendly and energy-saving cars. 1 4 percent of the world's energy is used for transportation, including 2 3 percent of oil produced annually. Some energy-saving measures in the transportation sector don't cost at all, such as keeping tires properly inflated, which can improve energy efficiency by 6%.

In addition, it is a gasoline-electric hybrid.

Eco-friendly vehicles such as cars can drive up to 20% more mileage than conventional cars with the same gasoline consumption.

6. Improve the energy-saving effect of refrigerators. More than half of the electricity used by residents is used for household appliances, and 1 5 percent of the world's CO2 emissions.

It is caused by the use of electricity by residents. Since the 80s of the 20th century, manufacturers have put refrigerators and other white goods.

energy efficiency has increased by about 70%, but there is still room for improvement in this area.

There are several ways to do this.

1. Industrial structure: Adjust and optimize the industrial structure and reasonably control the increment.

1. Mainly control or inhibit the excessive growth of high-energy-consuming and high-polluting industries;

2. Accelerate the elimination of backward and obsolete production capacity;

3. Gradually improve and promote the policies and measures for the optimization and adjustment of the industrial structure;

4. Vigorously promote the adjustment of the energy structure, and strive to promote the accelerated development of energy-saving services and high-tech industries.

Second, the implementation of energy-saving projects.

1. Increase investment in important projects and accelerate the implementation of key energy-saving projects;

2. Implement water resource conservation projects. Speed up the construction of water pollution control projects.

3. Promote the treatment of sulfur dioxide in coal-fired power plants. Raise funds for energy conservation and emission reduction through multiple channels.

3. Innovate models and accelerate the development of circular economy.

1. Vigorously promote the comprehensive utilization of resources and deepen the pilot project of circular economy.

2. Promote the utilization of garbage resources, waste reuse, industrial waste heat utilization, etc., and comprehensively promote cleaner production and low-carbon economy.

Fourth, relying on science and technology, innovation and development, accelerate the development and promotion of technology, research and development of new energy-saving technologies, energy-saving materials.

1. Accelerate the research and development and promotion of energy-saving and emission-reduction technologies, and accelerate the industrialization demonstration of energy-saving and emission-reduction technologies.

2. Accelerate the establishment of an energy-saving and emission-reduction technical service system and promote the healthy development of the environmental protection industry.

3. Improve the production efficiency of energy, and continuously develop new energy and new materials at the same time.

Fifth, consolidate the foundation of energy conservation and strengthen the management of energy conservation and emission reduction.

1. In terms of administrative management: establish an accountability system for energy conservation and emission reduction in government departments. False accompaniment.

2. Establish and improve the energy conservation and emission reduction index system, monitoring system and assessment system, and establish energy conservation standards.

6. Strengthen supervision and improve standards.

1. Increase the supervision and inspection and law enforcement of enterprises with high energy consumption and emissions.

2. Improve energy conservation and environmental protection standards, carry out special law enforcement inspections for energy conservation and emission reduction, and encourage energy conservation and emission reduction.

Seventh, gradually form an incentive and restraint mechanism.

1. Promote the product development network of resource industries and promote the development of technology.

2. The system is conducive to the fiscal policy of "energy conservation and emission reduction, energy conservation and efficiency improvement", and the implementation of tax policies that are conducive to "energy conservation and emission reduction, energy conservation and efficiency improvement".

When it comes to energy saving, the first thing that many people think of is to save electricity, and the most common method that we think of and use is to save the power consumption of various electrical appliances, such as don't adjust the hot air conditioner too low, don't adjust the cold air conditioner to too high temperature, choose a variety of energy-saving appliances, put the refrigerator when the hot food cools down, turn off the lights when people leave, and so on.

Many people pay attention to the energy consumption of electrical appliances, but rarely pay attention to the power loss on the line. Oxidation or loosening of the line interface, when the electrical appliances are used, will cause the circuit to heat up, and eliminate the detection of a large amount of electrical energy, therefore, in order to save energy, the wiring must be reasonable, do not leave too many terminals, and regularly check the wiring to eliminate the oxidation and loosening of the wiring. Some insulation and broken key lines are likely to be indirectly connected with the earth, which will lead to leakage at the damaged place, and in the long run, a large amount of discharge will be made to the earth, wasting electric energy.

From the perspective of yourself, you can reduce driving, take public transportation, save water, save paper, and do not use chopsticks once, and you can also save electricity.

When the TV is used, the volume is turned down, Lu Yu slows down the air conditioner and sets it to 26 degrees Celsius, and the electric early mold water heater should not be set to a long-term insulation state.

There are still 45 days to take the exam from today, and 43 days to prepare for the exam. 1. Line test (line Min 1) learning only defeat plan 1Mapping for two days, each morning and afternoon.

1. Choose energy-saving bulbs to save more electricity. Energy-saving bulbs are more power-efficient than regular bulbs. When there is no one in the room, choose energy-saving lamps instead of incandescent lamps, choose 10-watt bulbs instead of 75-watt bulbs, and pay attention to the brightness of the light bulbs.

2. For summer bathing, electric water heaters are generally used, and energy-saving ones are more energy-saving. Try to avoid showering during peak hours and turn down the water heater's control temperature button. In general, the choice of shower must be better than a bath.

3. Turn off the power in time if you don't use electricity, especially if you don't go home for a long time, you should turn off the air conditioning power and computer power when you leave, otherwise the electricity meter will still go, and the electricity consumption will be greater, and sometimes it is easy for people who steal electricity to enter.

4. The temperature of the air conditioner is generally 28 degrees Celsius, and it is the most comfortable power-saving mode under the constant temperature state. Household appliances should not be in standby mode all the time, especially for computers, refrigerators and other appliances that consume a lot of power, it is better to choose to enter the power-saving mode.

5. Choose a TV, you don't need to choose a large-size TV, it's not good for your eyes, choose an LCD TV, and the color and volume of the TV should be adjusted to the best state. When the weather is not too hot, there is no need to turn on the air conditioner all the time, and it is easy to cause problems such as colds often turned on at night.

6. When cooking, be sure to leave yourself a budget time, and remember to unplug the rice cooker at any time when you run out of it. For cooking, generally less use of induction cooker, induction cooker radiation, high power consumption, long-term use will also cause dizziness, choose a rice cooker to cook rice should also control the time.

There are many ways to save electricity, such as: turn off the lights at will, unplug the power or press the switch of the socket bar in time after using the electrical appliances, turn down the volume when using the TV, set the air conditioner to 26 degrees Celsius, and do not set the insulation state of the electric water heater for a long time, etc.

We hope you find ours helpful.

Personally, I think there are more energy-saving methods and measures, the first of which is the wrong time to use electricity, often now when we are at night. Residential electricity is basically not used, and at this time you can consider using electricity for industry.

1. The water used to wash rice can be used to water flowers and trees, or to flush toilets.

2. Garbage classification and disposal, which can be collected together, or homemade small handicrafts or sold to waste collectors.

3. Use beverage bottles to make flower pots, which can be used to grow plants. Small kettles can also be made from plastic bottles, and the size of the hole can be chiseled according to the size of the plant.

4 Old newspapers and books are gathered and sold in a certain amount. Paper companies can be reused, such as books, chopsticks, etc.

5. Use less disposable products. The manufacture of disposable products consumes a lot of raw materials and causes great harm to the environment. Such as: disposable chopsticks, disposable plastic cups, etc.

6. Bring cloth bags for shopping on the street, not plastic bags. Or don't throw away the plastic bag after use, wash it and reuse it.

7. Turn off lights, electric fans, TVs and other electrical appliances (power will also be consumed in standby mode) and faucets to save electricity and water.

8. In summer, the temperature of the air conditioner is limited to about 26 degrees (the air conditioner is too electricity-intensive), and the door should be closed when the air conditioner is turned on to reduce the loss of cold air.

9. Carry a handkerchief and reduce the use of paper towels, which not only saves and protects China's forest resources, but also effectively prevents resources and economic losses caused by natural disasters such as soil erosion and debris flows.

10. Wash clothes by hand as much as possible, instead of machine washing, which can reduce the amount of water used.

11. When washing clothes, the amount of laundry detergent is appropriate, or washed with soap, which can reduce the number of rinsing times and reduce water consumption.

12. Electrical appliances should be bought with energy-saving electrical appliances, and energy-saving lamps should be used for electric lights, although the effect is not obvious in the short term, but a lot of electricity can be saved under the long-term accumulation of the public.

13. Try to buy solar water heaters for water heaters, which not only reduces the use of gas and saves resources, but also makes reasonable use of solar energy and improves resource utilization.

14. Use bicycles instead of motorcycles, cars and other energy-dissipating vehicles, which not only saves energy, but also reduces greenhouse gas emissions.

15 In rural areas, the straw produced after the harvest of crops can be stacked to make feed for livestock, which not only makes efficient use of resources, but also reduces greenhouse gas emissions from combustion.
