A combined wind energy generator

technical field

The invention relates to a combined wind power generator, which belongs to the field of wind power generators.

Background technique

For many centuries, wind turbines, like hydraulic machinery, have been used as power sources to replace manpower and animal power, and have played an important role in the development of productivity. The widespread application of modern electromechanical power and the discovery of oil fields in the Middle East in the 1950s slowed down the development of wind turbines.

In the early 1970s, due to the "oil crisis", there was a problem of energy shortage. People realized the instability and limitation of conventional mineral energy supply, so seeking clean and renewable energy has become an important issue in the modern world. As a renewable and non-polluting natural energy, wind energy has aroused people's attention again. It is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. Broadly speaking, it is a thermal energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power utilizes natural energy. Much better than diesel power. But if it is used in an emergency, it is still not as good as a diesel generator. Wind power cannot be regarded as a backup power source, but it can be used for a long time. The use of wind power generators is to continuously turn wind energy into the standard electricity used by our families. The degree of saving is obvious. A family's annual electricity consumption only costs 20 yuan for battery fluid. However, the performance of the current wind turbines has been greatly improved compared to a few years ago. In the past, they were only used in a few remote areas. The wind turbines were connected to a 15W light bulb for direct electricity, and the light bulbs were often damaged when they were bright and dark. Now, due to technological progress, advanced chargers and inverters are adopted, and wind power generation has become a small system with certain technological content, and can replace normal commercial power under certain conditions. Mountainous areas can use this system to make a street lamp that does not cost money all year round; highways can use it as road sign lights at night; children in mountainous areas can study at night under fluorescent lights; Green power. Household wind generators can not only prevent power outages, but also increase the interest of life. In tourist attractions, border defense, schools, troops and even backward mountainous areas, wind turbines are becoming a hot spot for people to purchase. Radio amateurs can use their own technology to serve the people in mountainous areas in terms of wind power generation, so that people can watch TV and use electricity for lighting in sync with cities, and they can also make themselves rich through labor.
