Wind Turbine
AAB engages in the R&D and production of small and medium-sized wind turbines. Products are divided into horizontal axis and vertical axis wind turbines. wind turbines. More than ten models in a single series. The product is generally suitable for areas with good wind power conditions, far from the power grid, or areas with abnormal power grids to provide household electricity (such as electricity for simple electrical appliances such as televisions and lamps), monitoring installations, communication equipment. , etc. and other small and medium-sized users. Electricity consumption of electrical installations. The main application areas of products: road lighting, offices, residences, enterprises, agriculture, animal husbandry, plantation, animal husbandry, tourism, advertising, service industries, ports, mountainous areas, forestry areas, railways, oil, military border posts, communications relays. Stations, road and rail signal stations, geological exploration and field survey workstations and other areas with inconvenient power supply.

But: I have never used it, so I don't know not how reliable it is, and a big problem with wind power generation is the amount of electricity generated. She is unstable. If voltage and current stabilizing devices, batteries, etc. are added, that is, the external expansion part, the price of the expansion part is much higher than the price of the expansion part.fan price. Additionally, if the home uses air conditioners, refrigerators, electric cookware, and other equipment, a set of fans will definitely not be able to meet the demand when power consumption is high. But for families, when power consumption is low, fans. won't stop, and most of them won't stop. There is no way to store the remaining energy

Everyone should be able to light a candle with a match, but it's amazing to light a candle without the match touching the wick. Speaking of which, I discovered this phenomenon by accident. One day, while I was burning orange peels after lighting a candle, the candle I had lit was blown away by a gust of wind, so Istruck a match 6 cm from the candle wick. time, the candle burned on its own. I found this very strange. When I got back to school, I asked my tutor to do a little experiment like this today and asked me to look carefully and listen carefully.
The experiment has begun. The teacher first took a match out of the matchbox, struck it, and the match burned. After the candle had burned for a while, he blew it out. . Only the wick was visible. There was a wisp of green smoke coming from the fire. I felt very strange. Why did the professor put out the fire? Before I could react, I saw the teacher take out a match from the matchbox again at lightning speed, and quickly struck the match which was about 6 cm above the wick of the matchbox. candle, and dancing flames followed with green smoke. , suddenlySuddenly, the flame “hissed”like a shooting star and fell into the arms of the candle mother. The candle burned suddenly and the flame danced with the breeze. The experiment was successful, and I did this experiment again and again, but I still don't know the reason. The teacher pretended to be mysterious and simply asked the students to try it one by one, without explaining what had happened all night. When the students were almost finished, the teacher finally revealed the secret. It turned out that after the candle was extinguished, it seemed that there was no source of fire, but in fact there was still a stream of combustible gas flowing over the candle. The second time, we lit the flammable gas about 6 cm from the candle, and this gas ignited the candle wick, resulting in this phenomenon.

What makes the 21st century so prosperous? It's scientific! Our lives are independentinseparable from the word “science”. If you think science is just about tinkering and experimenting, you're dead wrong. There is too much science in our lives. They are as big as a space shuttle flying through the sky, or as small as the reason birds can fly freely. You could say they are everywhere.
How important is science to human beings? What would happen if humans abandoned science? Just give a few examples and you will understand: the scientist Edison invented electric light, so people could see light at any time; physicist Newton discovered universal gravity, which made us understand why we can't fly... There are so many. There are so many such examples that we cannot count them. They have brought a lot of help to humanity. These things all belong to science. However, regardlessthe greatness of these people and these things, they are only a drop of water in the world. infinite ocean of science. If we leave this ocean of science, then human history could go back tens of millions of years. In other words, what drives human history is science!
The history of Father Sun's electricity production
The history of Father Sun's electricity production? In daily life, many parents tell stories to their children, because some stories help children's imagination. Some parents also educate their children by telling stories. Below I will share the story of Father Sun generating electricity.
The history of electricity production from Father Sun 1The history of electricity production from Father Sun
Coal was extracted from the ground. He went to the power plant and sent electricityquoted. The lights were on, the machines were working and people were congratulating him.
Coal thought he was big and very proud, so he said to the sun, wind and sea water: "Hey, friends, let's compare which capacity is larger, d 'okay?"
< p> Sea water He said: "Compare, I have countless treasures Fish and shrimp grow in my arms, and there are a lot of iodine, potassium. , uranium and other minerals in the sea. "The wind said: "I can push the sailboat forward, and I can also help people plow the clouds and to sow rain, to regulate temperature. "
The sun also said: "I can bring light and warmth to the earth. Without me, the day on earth would be as bad as the night..."
Mei hurriedly interrupted them and said: "No, no, let's compete: see who can do it. The lights come on. . "
While he was speaking, the coal blewin the boiler, burned red, released a lot of heat, turned the water in the boiler into steam, drove the turbogenerator and made the electric lamp shine.
When Mei was feeling proud, he suddenly heard a kind voice say: “Son, you must be humble. "
Coal raised his head and found that the person talking to him was Taiyang. He asked, "Child? Who is your child? "
Taiyang said with a smile: "You follow me My child, have you forgotten? Coal energy is obtained and stored from me. "
Coal shook his head and said, "How is that possible?"
The sun told him that hundreds of millions of years ago, the trees of the large forest absorbed the sun's energy for photosynthesis. Later, the trees turned into coal, which actually stored the sun's energy. After all, the heat emitted by the coal was converted from it. of the sun's energy there are ctens of millions of years.
Hearing this, Mei's eyes turned around and he said, "But now, can you use solar energy to turn on the lights?" »
“Of course you can! » and it turned out to be Chuanbai. A scientist in a lab coat took Coal to tour the solar plant and the hydroelectric and wind power plants.
The sun patiently asked Coal: “Child, have you seen everything. ?"
Coal lowered his head: "Father Sun produces electricity, which is much simpler and cleaner than mine. The seawater and the wind are no worse than me!"
When the seawater and the wind heard this, they also became happy. They held hands and said shouted loudly: “Actually, we are all beautiful because of the sun that shines on the earth. The sun is also the source of our energy!"
Everyone looked at the sun. The sun blinkedeyes and smiled.
The story of the generation of Father Sun. electricity 2Story of the magic pen
An old man gave Xiaofeng a pencil. It was not an ordinary pencil, but a magic pen. At night, Xiaofeng went to bed. The pencil stood up on its own and drew a mouse on the paper. As soon as he finished, the mouse yawned, stretched and came to life.
