At least it is about 300 meters and the height can reach 400 meters. Nowadays, the shooting distances of different types of cameras are also different. We see that these electronic devices are often equipped with radar waves to detect the speed of vehicles. Now the detection distance on the highway is at least 300 meters, and the highest. can reach 400 meters.
Will wind turbines turn in the direction of the wind?
There are two points:
Wind turbines do not produce electricity at all time. When there is no wind, it should still be on standby;
The height of modern megawatt-level wind turbines is typically 65 to 90 meters and they are in open wilderness . If there is no wind when you are upstairs, there could be two reasons: First, your building is not high enough. The most common wind turbine 80 meters high is equivalent toa building of 25 to 30 floors. The second floor is built in town. There are too many buildings in the city, making the wind unstable and turbulent everywhere. For example, a city is like the bottom of a river with many large rocks and the water flow is unstable and irregular. So when you are standing upstairs, sometimes there may be no wind and sometimes there may be gusty winds. The wind turbine is in the wind field, there is no obstruction, the wind speed is stable and lasts a long time (wind measurement and corresponding simulation calculation are required). Additionally, specific fan positions are calculated to ensure low turbulence and stable wind speed.
So the wind upstairs is different from the wind field, and the height of the building is different from the height of the wind turbine. If you don't feel the wind when you stand upstairs, you do. This does not mean that the energy iswind turbine cannot be produced.
Yes, the cabin can rotate and is always facing the wind. The technical term is yaw. Of course, the pod will not always rotate in one direction, such as clockwise or counterclockwise. If the wind direction is unlucky, it will always move in the same direction. The fan will spin a maximum of seven or eight hundred degrees. must also be actively running. This is called undocking. Prevent the cables inside from being pulled out.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism and an energy storage device.gie.
Detailed information:
The principle of wind energy production is to Use wind power to spin the windmill blades, then increase the rotation speed with the speed boost to encourage the generator to produce electricity. According to current wind turbine technology, electricity production can start at a breeze speed of around three meters per second (the breeze level). Wind energy is becoming a craze around the world because it poses no fuel problems and does not produce radiation or air pollution.
Generally speaking, a wind turbine is a thermal energy engine that uses the sun as the heat source and the atmosphere as the working fluid. Wind energy uses natural energy. This is much better than diesel power generation. But if it is used in an emergency,it is still not as efficient as a diesel generator. Wind power cannot be considered as a backup energy source; but it can be used for a long time.
