Abstract

Transformatorul cu tensiune reglabila, conform inventiei, în scopul reglarii tensiunii, este constituit dintr-un transformator principal si un transformator auxiliar, de reglaj, cu miez saturabil în curent continu printr-o bobina de comanda, care au legate în serie înfasurarile primare si de asemenea înfasurarile secundare, dar în opozitie de faza si care poate functiona între doua cazuri extreme si anume, primul caz cînd miezul transformatorului auxiliar nu este saturat în curent continuu, caz în care tensiunea de intrare se repartizeaza proportional cu impedanta de intrare a celor doua intrari primare, iar în secundare se introduc de asemenea tensiuni proportionale cu tensiunile din primar care scad, tensiunea auxiliara din tensiunea transformatorului principal, iar în al doilea caz, cînd miezul transformatorului auxiliar este saturat, caz în care, tensiunea de intrare este repartizata toata pe înfasurarea transformatorului principal, iar în secundar cu tensiunea de intrare, pe cînd în secundarul transformatorului auxiliar tensiunea indusa este nula, astfel ca în final tensiunea de iesire va fi egala cu tensiunea din secundarul transformatorului principal.The voltage-regulated transformer according to the invention for the purpose of voltage regulation is constituted by a main transformer and an auxiliary regulator with a saturable core in direct current through a control coil having in series the primary and such as the secondary turns but in opposition to the phase and which can function between two extreme cases, namely the first case when the auxiliary transformer core is not saturated in DC, in which case the input voltage is distributed in proportion to the input impedance of the two inputs primary, and secondary voltages are also proportional to the primary stresses that decrease, the auxiliary voltage from the main transformer voltage, and in the second case, when the auxiliary transformer core is saturated, in which case the input voltage is distributed all over the the main transformer, and in secondary with the i voltage the induced voltage is zero, so that the output voltage in the end will be equal to the voltage in the main transformer secondary.
