The utility model belongs to the field of energy, in particular to energy-clean devices for generating electric current.

Devices of this type can be used as means for industrial production of electricity, for example as power plants.

In connection with the growth of the use of electric energy, the search for sources for obtaining cheap electric energy is carried out. Known devices that use exhaustible energy sources, such as fossils, which are expendable, pollute the environment and deplete natural sources, resulting in high-cost electricity, and those that use non-exhaustible energy sources, such as wind energy, waves, the sun, which also have many disadvantages.

Among the well-known means of generating electricity is a wind farm, which consists of a wind turbine (which converts the kinetic energy of the wind into mechanical energy), the shaft of which is connected by means of a gearbox to an electrical energy generator, which converts the mechanical energy from the shaft into electrical energy, which is transmitted through the gearbox .

Well-known devices for generating electricity using the sun's energy are solar panels, and using water energy - hydroelectric plants, which carry out an identical transformation of mechanical energy into electrical energy.

The closest analogue is a network power plant, manufactured by Boyag Tesp, with a capacity of 100 kW, consisting of a block of solar panels and an inverter for transferring electric current to the general electric network (pPOrzv//50Yag-iesp.sot.tsa/pa/sotriieie-zuzietv/zeiemuye- viapsipeirmogk-5iayop-100-Km-tog-Bivipe 55. PIti).

Both the closest analog and other means of generating electrical energy have a number of disadvantages, which consist of the following negative factors, for example: - for hydroelectric power stations, this is the possibility of construction exclusively near water bodies, difficulty in construction, large dimensions, danger of a dam breach; - for wind generators - the noise of wind generators, which is caused by the rotation of the blades of the windmill, the complexity of the construction of the wind generator and its maintenance, low wear resistance, - the solar power plant, as the closest analogue, despite its modularity and

With the possibility of changing the configuration (location of panels in space), for example on the ground or on the external surfaces of construction structures, it has a low electricity production with large dimensions and area of solar panels, to obtain a power of 100 kW/h, 250 solar panels with a size of 2x1 m are needed, which is equal to area of 700 m.

In addition, the production of electricity both with the help of wind power plants and solar power plants is uneven due to the variability of sources of solar energy and wind energy - the wind almost always blows unevenly, the generator will not work constantly, giving more or less power, and the intensity of solar radiation changes depending on the season and time of day.

The task of the useful model is to improve the design of known analogues of the device, namely: increase in electricity production, increase in the efficiency of the device, decrease in the dimensions of the device, decrease in construction costs and the possibility of moving the device, taking into account its dimensions, without significant costs for dismantling and installed in a new place, as well as ensuring the possibility of using the device as an independent power plant without external sources of electricity after its start-up.

To solve the given problem, the device for generating electricity, containing means for converting solar energy into electric or other external source of electric energy with a capacity of up to 100 kW/h, according to a useful model, is additionally equipped with an asynchronous electric motor with a capacity of 90-100 kW/h with the possibility rotation of the rotor at a speed of 750 rpm, with a torque of 1199 Nm, where the engine is connected to an external source of electrical energy by conductors, and its rotor, through a rigid connection, such as a flange, to the flywheel shaft with a mass of 0.220 t and with a radius of 0.20 m, with the possibility of rotation of the output shaft of an asynchronous electric motor with an actual rotation frequency of 740 rpm and the creation of kinetic energy of 95016 J, the wheel through a rigid connection is connected to a speed reducer with the possibility of increasing the torque of 95016 Nm , with a rotation frequency of 740 rpm, up to 4374 kNm with a rotation frequency of 16.07 rpm, in a ratio of 46.04, the gearbox is connected through a rigid connection, such as a flange, with a speed multiplier (multiplier) with the possibility increasing the speed from 16.07 rpm to 1500 rpm in a ratio of 93.34, with a torque of 46860 Nm, the reduction gear is connected through a rigid coupling to a rare earth Ma-Re-B alternator with constant with magnets, 3-phase, with the possibility of generating electricity with a power of 5 mW/h.

At the same time, the rare-earth Ma-Re-B alternating current generator can be connected by conductors to an asynchronous electric motor through a transformer substation with no less than one similar device for generating electricity, but no more than 45 series-connected similar devices for generating electricity of electricity with a capacity of up to 225 mW.

The use of an improved design of the device for the production of electrical energy in contrast to both the closest and other analogs: 1) increases the production of electricity, other things being equal: with the consumption of electrical energy from a solar power plant of 100 kW/h, the production of electricity is up to 5 mW/h, or in in the case of using several similar devices connected together, the production of electricity can be increased to 225 mW/h, with the same consumption of 100 kW/h; 2) makes it possible to use the device without alternative sources of electricity, such as, for example, solar panels or wind generators - instead of alternative sources of electricity, electricity from the general power grid is used; 3) makes the construction of power plants cheaper: if we compare, for example, with a wind power plant, the price reduction can be from 2 million dollars. up to 500,000 dollars; 4) makes it possible to move such a power plant if there is an external source of electrical energy, for example, the possibility of connecting to the general network or connecting to any of the known sources of conversion of natural energy into electrical energy.
