1. What are the links in the journey of Eko electric power?
Generation - Transformation - transmission - Transformation - consumption
① The source of power transmission: power generation
② Medium of power transmission: transmission
③ Terminal of power transmission: electricity consumption
Through the power plant to send electricity, into the substation to raise the voltage, so that the power can be sent further, the line through the transmission tower to the distance. The voltage will be reduced through the substation for the use of factories and large shopping malls, and then the voltage will be lowered through the transformer for home use.
2. How fast is electricity?
Power transmission is the "sixth mode of transportation" after road, railway, waterway, aviation and pipeline transportation. The electric field transmits at the speed of 300, 000 kilometers per second, generating, transmitting, distributing and using electricity at the same time. In order to supply power reliably, optimize resources and reduce the cost of electricity, we connect the transmission lines into a large power grid for people to use. The electric field can travel around the earth about eight times a second.
3. Why should we change the pressure?
People can save water in cans, but electricity can't be stored, so it has to be made in a flash and transported by wire. In order to allow the current to carry further, voltage should be added to the electricity. After the current flows out of the step-up substation, it will enter the high-voltage line. High voltage lines are far away from the ground and are mounted on huge towers that carry electricity from the power station to all parts of the country.
4. What energy sources can generate electricity?
The energy that can generate electricity is mainly divided into traditional energy and renewable energy. At present, China mainly uses traditional energy for power generation. Traditional energy includes coal, oil, natural gas, etc.; renewable energy includes nuclear energy, water energy, geothermal energy, solar energy, wind energy, etc.
5. What is "power transmission from west to East"?
The western region of China is rich in water resources and lacks of development; the eastern region is economically developed and lacks energy. Through the energy development strategy of "power transmission from west to East", hydropower and thermal power in Western China will be developed and transported to the eastern region where power is scarce. This not only provides a new historical opportunity for the western provinces to transform the advantages of power resources into economic advantages, but also eases the current situation of power shortage in the East, promotes the optimal allocation of resources in a wide range, and achieves the best utilization of limited resources.
6. Why patrol?
Line workers patrol along the wire tower to check whether the equipment is complete. If it is damaged, it should be reported to the superior department for emergency repair, so as to avoid delaying the normal transmission of power supply. Some of them have to cross mountains and mountains. After the UHV line inspector boarded the high-voltage line, the shortest distance between the cable under his feet and the ground was 12 meters, and the highest was 800 meters. Psychological quality and physical fitness should be absolutely excellent.
7. How to deal with ice snow disaster in transmission line?
The snowstorm will make the wire on the formation of ice, some towers because of unable to withstand the gravity of ice and snow, collapsed to the ground. Now the newly developed DC ice melting device is installed on the icing line, and the ice and snow can be melted a little bit.
8. Is there radiation in the high voltage line?
Many people will wonder whether the electromagnetic environment around power transmission and transformation facilities is safe. In fact, the power frequency of China's power transmission and transformation facilities is 50 Hz. Only the power frequency of more than 3000 Hz will spread in the form of electromagnetic wave to form radiation. Therefore, we need not worry about the impact of substation or high-voltage wire on health and safety.
9. What does one degree of electricity do?
The best 1 kilowatt hour: the electric bicycle runs about 80 kilometers
The coolest 1 degree of electricity: the ordinary electric fan runs for about 15 hours
Cleanest 1 degree of electricity: 9 watt energy saving lamp on for more than 100 hours
The most entertaining kilowatt hour: watching TV for about 10 hour
The most thirst quenching 1 degree electricity: boil water about 8 liters
One degree electricity: about 15 bottles of beer
The most warm 1 degree electricity: weaving about 10 meters
10. What is the effect of saving 1 kilowatt hour of electricity per person per day?
Yike electric power shares 1.33 billion people in China, and can save 1.33 billion kwh of electricity a year, assuming that 1 kwh power is 0.61 yuan, 13.3 × 365 = 485.45 billion kwh; 4854.5 × 0.61 ≈ 296.12 billion yuan. A kilowatt hour of electricity requires 0.3 kg of standard coal, which produces 0.8 kg of carbon dioxide. According to the above algorithm: 4854.5 × 0.8 = 388.36 billion kg = 388.36 million tons, which can reduce 388.36 million tons of carbon dioxide emissions.
