If you ask about large wind turbines, the 50-meter tower barrel and distribution cabinet produced by Games (Gemisa) in Spain are expected to cost about 6 million yuan, and the 25-meter blade costs about 100,000 yuan in total. 3 blades can produce electricity. The price is estimated between 8 and 9 million. Tianjing Shenzhou may be cheaper. Dongqi (Vestas) machines and Sinovel towers are less than 70 meters and less than 10 million.
If it is a domestic wind turbine, it will cost about 2000-2500
New motor (pure electric drive), such good technology, it's a pity that There isn't any material to make it!
Normally 0.8 to 0.95 is enough. The impact of being too high or too low can be compared to a bucket carrying water. The water is like the work we need, and the bucket is like the reactive power. Only when there is a bucket can weWe lift the water.
But too high a power factor is like filling a very full bucket. It doesn't matter if it's stable. Once there is a slight disturbance, the water will flow easily; it also has weight. and consumes energy, so the efficiency is low; if it is installed in 8 or 9 points and is not afraid of disturbances, the efficiency will be higher;
The size of the power factor is related to the load properties of the circuit. For example, the power factor of resistive loads such as incandescent light bulbs and resistance ovens is 1. Typically the power factor of circuits. with inductive loads is less than 1.
The power factor is a coefficient that measures the efficiency of electrical equipment. A low power factor indicates that the circuit uses significant reactive power for the conversion of the alternating magnetic field, thereby reducing the use of the equationipement and increasing line power losses.
Detailed information:
Nonlinear loads distort the current waveform from a sine wave to other waveforms. In addition to the original power supply frequency (fundamental frequency), the input current of a nonlinear load also contains many high-frequency harmonic current components. Filters composed of linear components such as capacitors and inductors can reduceuit harmonic currents entering the electrical system from the load end.
Capacitors connected in parallel to the line for reactive power compensation will amplify the harmonics, making the system voltage and current distortion more serious. In addition, the harmonic current superimposed on the fundamental current of the capacitor will increase the effective current value of the capacitor, causing an increase in temperature and reducing the life of the capacitor.

The idea is very good and deserves recognition if this machine can really achieve continuous supply without consuming anything other than . itself if the power is , then we can say that it is a perpetual motion machine. if it is realIf this machine succeeds, it will cause a new global industrial revolution and humanity will enter a new era. Whateverdifficulty of making this machine, there are some points of knowledge that I would like to discuss together; first of all, the principle of this machine that you mentioned violates the law of conservation of energy. The current reversal of all electronics. The systems and compression of the air system, the work of the power generation system and the connection of mechanical components require energy consumption. Once the power of an electric motor is transmitted through so many connections, much of the power itself is lost. If a generator is used to produce electricity, then it can only be The power required by the generator to produce electricity is less than the power transmitted by the motor, the power of the electricity generated by the generator will not be greater than the power consumed; by the generator itself, because there is energy consumption in the middle. Of soulHowever, the energy power consumed by the engine is also greater than the work done by itself, a new problem arises: the power emitted by the generator cannot meet the needs of the engine. Power can only be transmitted efficiently and becomes smaller and smaller. If you want this machine to move, you need a new one, but it doesn't matter how the electronic systems, hydraulic systems and pneumatic systems. , and mechanical systems exist in various forms. They can only conduct energy but cannot amplify it. Lift a water bucket directly by hand or lift a water bucket with a labor-saving pulley. The energy required is the same, but the form. is different. How to amplify power is a problem that has been bothering me for a long time, I wonder if permanent magnets can be added to increasethe power. I hope we can discuss it together.
Internal pressure circulation, a pneumatic turbine drives the generator to produce electricity. Pressure generation also requires energy consumption, but it simply converts motor power into pneumatic power. The pneumatic power is then converted into electrical power. How can it start without new power in the middle? Even if the internal pressure of the engine is raised to a high level, a high-power generator can produce electricity, but the power generated by the high-power generator will not exceed the power consumed by the engine. In this case, that of the machine. energy consumption will still not be self-sufficient. An electric air pump can generate a lot of air pressure when driven by a small motor. It seems that the power is increased, but in fact iThis is simply an equivalent replacement. It must be lower than the original power due to consumption. A small motor saves effort but costs distance. Is this the same situation?
