Description

 Method for wired power supply, base station transmission and active wireless reception of electric energy in power grids

 The invention relates to a method for wired power supply, base station transmission and active wireless reception of electric energy, which is realized by a power grid wired power supply system device base station transmission system device and an active wireless reception power system device. Background technique:

 In 1873, the British scientist Maxwell established Maxwell's equations. The results of previous research by Faraday, Ampere, and Gauss formed the theorem. Maxwell believed that electromagnetic energy exists in the form of waves, that is, electromagnetic waves.

 In daily life, use water as a physical experiment, put the water in a round container, open one or several holes around the bottom or bottom of the container, install the valve, when you open the valve, the water will flow out, the valve port The larger the water, the greater the flow of water. The more valves there are, the more water flows. When we look at the water level, we will see that the water produces one or several vortices of different sizes. In the air, the higher the water level, the pressure. The larger the flow rate, the larger the eddy current, the water level and pressure, the flow rate and the eddy current are proportional, and the water level and eddy current, pressure and flow rate cannot form the positive and negative ratio. Instead, according to the valve to control the eddy current, if the water is in the container, let it flow out, can it produce eddy currents, the answer is yes. If chemical raw materials are placed in the water (regardless of chemical changes), can the material materials flow out with the water? As long as there is enough space, it is completely ok, physically just changing its shape.

 There are many similarities between electricity and water. Electricity has current, water has water flow, electricity has magnetic flux density in the air, and water has humidity in the air. The current has a density, and the water flow also has a specific gravity. Water can be sprayed in the air, electricity can also be transmitted in the air. Water brings happiness and disaster to human beings. Electricity is the same. It is just how people develop, use, overcome and prevent it.

 The current caused by induction in the conductive object is eddy current. In the electromagnetic wave, the magnetic flux has density and the current also has density. Therefore, we use the volume integral method to scatter the electromagnetic wave in the electromagnetic wave.

For example, one or more pumps in an electric irrigation station pump the water from the rivers and reservoirs to the ground through electric motors, diesel engines, etc., and drain them through the trenches or pipes to the farmland or Where water is needed, if the ground drain is generated through the drain of the trench, the water loss is large and the water resources are low. If the pipeline is drained, the loss is small, almost zero, and the water resource utilization rate is high. The water pumped out by the electric irrigation station is natural water, which can be used in places where natural water is needed. If it requires a lot of natural water and a small amount of purified water, it is not difficult to do. Just add water purification equipment at the electric irrigation station. The erection or buried pipelines can be transported side by side or separated by the same pipe.

 From the existing patented technology analysis, wireless power supply and wireless reception, especially the invention patents applied by Sony Corporation of Japan, "power supply device, power receiving device, wireless power supply device and wireless power transmission method", using magnetic resonance and magnetic induction phenomena and Active transmission and passive reception, which have certain shortcomings of directionality and short distance. Although the emission voltage and current are constant, the received power is affected by the distance to generate voltage fluctuations, and the long distance voltage is low, short distance. The voltage is high. In particular, it is difficult for a mobile power receiver to receive stable power or is unable to receive at all, which is inefficient.
