This work is briefly acquainted with the history and current trends in the art wind turbines. In addition to distribution and description 3 way switches of individual components also addresses environmental impacts.
One of the main directions which will have our company in the near future pay more attention to the question of how to ensure the growing demand for electricity in the world and also look at the pure form of the acquisition. 3 way switches In addition to current trends in the orientation of the environmentally focused projects and associated ever increasing need to find new ideas in recent years acquired 3 way switches a method of obtaining energy from the wind greatly in importance. It is important that in every way technical 3 way switches applications can still improve existing technologies. This will address important issues of current technology and at the same time push the limits of our capabilities further. [1]
The use of wind power dates back several thousand years into the past. Man this power used for ship propulsion. These simple 3 way switches old vessels are more than 5,000 years old and come from ancient Egypt. The earliest mills powered by wind coming 3 way switches from today's Afghanistan and are 2,700 years old. They are normally used for grinding corn and irrigated fields in the islands of the Mediterranean. Crete are used today. Likewise in the Netherlands were used windmills to pump water from low-lying areas (Figure 1).
In 1854 appeared the first wind-powered water pump. Consisted of a rosette, which were coated tarpaulin and wooden 3 way switches tail, which filmed the entire plant downwind. In 1940, those working for more than 6 million. They were used to pump water and to generate electricity energie.20 century meant the emergence of new energy sources - electricity, oil and gas. Wind pumps gradually pushed. In the 70 years during the oil crisis, interest in wind energy 3 way switches revived. Many states encourage research and development of wind energy. [2]
Are an important part of the turbine that capture the wind energy. The leaves are made of laminates, polyester, and is also used sometimes 3 way switches wood. These materials are characterized by a combination of flexibility and strength. These materials do not interfere with television and other signals. Averages for large turbines is between 25 and more than 50 meters and can weigh up to one ton.
In many turbines 3 way switches is the activity of the individual components controlled electronically and can be controlled remotely. Used electronics keeps the voltage at varying speed of the generator. diversity of wind turbines, the vast majority of modern turbines is available in two configurations - with a horizontal or vertical axis.
Wind power divided by the size of the installed capacity: microreservoir - with a capacity of up to 30kW - supply direct current to charge batteries medium sized power - with power up to 100kW - alternating current supplied to the grid large power plants - with an output of 100kW - alternating current supplied to the grid
Small wind turbines in the world mostly used as a standalone power source. In some cases, however, even these small systems to be connected to the public electricity 3 way switches network, which allows the owner of such a system to reduce the cost of buying electricity while in the case of excess supply it generated electricity to the grid. Ordering and delivery to the network is done by automatic switches. Measure the consumption of electricity is usually connected such that the supply of electricity to the network revolves vice versa.
Such turbines are currently produced by a number of companies in a wide power range from a few watts to several thousand W. Small wind turbine with power from 100 to 500 W is in a good windy spot (with average wind speeds greater than 5 m / s) capable of very cheaply supply energy to the battery and then provide energy for example. lighting, power electrical appliances such as radio or television. In the past (the early 70 years) was the reliability of these turbines problematic. However, at present the market for turbines that can withstand even the harshest conditions and require little maintenance (every 5 years). The reliability 3 way switches of these systems are aligned such confidence. systems with solar cells.
The use of small wind turbines for the isolated users showed more favorable than such use. diesel generators or extension of power lines. The advantage is that the wind systems are not only relatively small, but can be quickly built. In many countries, the extension of power lines to the customer about one kilometer more expensive than the cost to build a small wind system. Although wind turbines are characterized by higher investment costs
