Abstract

Es por consiguiente un objeto de la presente invención proporcionar una estructura de electrodos perfeccionada susceptible de ser utilizada en un interruptor de circuito y está exenta de los inconvenientes que se citan anteriormente existentes en las extructuras de electrodos de tipo convencional. Otro objeto de la presente invención es proporcionar una estructura de electrodos perfeccionada que puede promover el movimiento circunferencial de una columna de arco generada durante la interrupción del circuito. Otro objeto de la presente invención es proporcionar una estructura de electrodos perfeccionada que puede aportar gran capacidad y eficacia de interrupción del circuito. Estos y otros objetos se lográn según la presente invención proporcionando una estructura de electrodos que comprende un par de electrodos, uno de los cuales es relativamente movible con respecto al otro en y fuera de ajuste recíproco, comprendiendo al menos uno de los electrodos una sección de contacto anular y una sección impulsora de arco que rodea la mencionada sección de contacto anular, estando formada la referida sección impulsora de arco con una pluralidad de ranuras que se extienden hacia dentro a partir de su periferia exterior dividiéndola en segmentos conductores respectivos, hallándose las ranuras inclinadas en ángulo con respecto al radio de la sección impulsora de arco y asimismo inclinadas en ángulo con respecto al eje geométrico de dicha sección impulsora, de tal manera que los segmentos conductores de arco pueden solapar los segmentos correspondientes contiguos a través de las ranuras inclinadas. Los objetos que se mencionan anteriormente y otros adicionales y características de la presente invención se evidenciarán a partir de la descripción que sigue, en la cual se han expuesto las estructuras preferidas en detalle conjuntamente con los planos que se acompañan.
