Description

DESCRIPTION P; : -V method of generating an electromotive force. To the author's testimony of F. L. Shapiro, wgg yleanom, 25 November 1934 (cf. ner. No. 151843). Published on August 31, 2008. The present invention relates to a method of generating an electromotive force based on a change in magnetic flux, which is changed by heating above the Curie point and cooling51 below this point, the magnetic permeability of the iron core of the current transformer. In the drawing fkg. 1 shows an exemplary form of a transformer according to the invention; FIG. 2 and 3 are the corresponding curves. FIG. Figure 2 shows the curves of the magnetic permeability (Jfrom temperature (f) for one of the sorts of iron at different strengths H magnetic field at temperatures close to critical (the temperature at which ferromagnetism disappears, i becomes 1. For iron grade (Fig. 1): - 786 °, for nickel / „„ 300 °. A small change in temperature causes a sharp change in the value of several thousand hours to 1.1- If the ferromagnetic magnetic core is alternately heated and cooled so that in order for its temperature to be 100, then the pulsating magnetic flux in it will be a pulsating magnetic flux in the permanent magnet and, therefore, in the winding, in terms of emf, and current. The source of electrical energy is heat, supplied to made with the help of an exemplary device of a transformer depicted in phi 1. Pumps 3 from boiler 1 and cooler 2 drive cold (hot) gases into the coils 7 of the transformer magnetic circuit. Valves 4 and 5 are periodically opened and closed by a special servomotor. When the valves 4 are closed, the valves 5 are open and the gases are directed so that when the first part of the magnet conductor heats up, the left cools and back. FIG. 3 curve 1 shows the change in the magnetic permeability of the right side, the curve of the 2-left part, and curve 3 gives the total magnetic conductivity, which, as can be seen from the curve, remains constant. Therefore, the total magnetic flux passing through the excitation coil 8 (Fig. 1) will be constant, it does not occur in it.

T gt. , Prompolngraf Tambovsk 12. Z. K. 4147-5 (X) E.D. c. and there will be no transfer of energy from the excitation circuit to the working circuit (coil 11). In order to ensure this, even at a strictly constant total magnetic conductivity, it is necessary to make the core of the coil 8 highly saturated. The constant total magnetic flux branches out between the right and left parts of the magnet wire proportional to their tt and therefore will be pulsating in each of them (Fig. 3 curves 1 and 2). In coils M, pulsating flows will cause variables e. D. s., shifted from each other in phase by 18 (f (Fig. 3 - curves 1 and 2)., With the appropriate connection of the coils, the total ed s will be the total (curve 3). In Fig. 3 e. The spacecraft is conventionally shown rectangular, in reality it will vary along a periodic curve, which can be brought closer to a sinusoid by a special design of valves, magnetic conductor, etc. Thus, according to the proposed method, heat energy will be converted into electrical energy. invention.
