Transformer amplifier relates to the field of electrotechnics that encludes distribution of electrical energy. During distribution of electric energy with distribution transformers the range for regulation of voltage is ñ5%,while with significant voltage downfalls in the net from 5 % and cannot attain the correct function of electric appliances, thus it imperils their function and brings to the possible burning out. This shortcoming is now solved by building up or construction of new transformer station. As a possible technical solution for imperrilled consumers is the application of the transformer amplifier that at the place in the net with reduced voltage increases and maintains the power that can overtake the consumer, corresponding to the squared relation of the secondary and primary voltage. Transformer amplifier comprises from the core of amplifiers of complex sheets per numbers from (1) -(10) thus by arrangement of the sheets three free spaces are framed among which are set transformer sheets that interweave mutually where they successively cover frontal or lateral points of touch of sheets. Two free areas in the core shaped as parallelepiped are mutually in parallel and detached by contours of sheet metal packages (1) is set in the first part of the primary winding (13). In the first and the third free space around the package of the yoke of sheet metals (2) and (7) is set in the second part of the primary winding (14). In the second and third free space around the package of the sheet metals (2) and (6) sets the secondary winding (15). In the third free space around the sheets (8) is set the winding (16). Mutual coupling of the winding achieves reduction in flux with winding of the incitation (16) with flux of the second part of the primary winding (13). Regulation of distribution of the flux is carried along with the application of voltage comparators of standard undervoltage relay by coupling thereof to the voltage of the network to the incitation of the winding (16) and with standard voltage values of the net, the incitation voltage interrupts and switches off. |
