Abstract

Perfeccionamientos en aparatos de control de corriente alterna caracterizados por la disposición de un arrollamiento de reactancia incluido en el circuito de corriente alterna que ha de controlarse y provisto de un núcleo magnético adaptado para ser saturado magnéticamente por medio de un arrollamiento de saturación al que se suministra una fuerza de control relativamente pequeña y en el que el aparato comprende esencialmente dos arrollamientos de reactancia provisto de núcleos magnético y unido en paralelo uno a otro en el circuito de corriente alterna a controlar una corriente rectificada derivada del circuito a controlar a través de una serie o transformador de corriente hace que atraviesen los arrollamientos de reactancia en serie unO con otro mientras que los núcleos magnéticos llevan un arrollamiento o arrollamientos de saturación atravesado por la corriente de control con los fines especificados.Improvements in alternating current control devices characterized by the provision of a reactance winding included in the alternating current circuit to be controlled and provided with a magnetic core adapted to be magnetically saturated by means of a saturation winding to which it is supplied a relatively small control force and in which the apparatus essentially comprises two reactance windings provided with magnetic cores and connected in parallel one to another in the alternating current circuit to control a rectified current derived from the circuit to be controlled through a series The current transformer causes the reactance windings to pass through in series with one another while the magnetic cores carry a saturation winding or windings crossed by the control current for the specified purposes.
