Abstract

La presente invencion se refiere a un aparato interruptor eléctrico que tiene sus contactos de interruptor protegidos contra oleadas de corriente, caracterizado porque comprende; primero y segundo conductores; un circuito interruptor conectado entre dichos primero y segundo conductores e incluyendo un resistor de polarización y medios interruptores conectados respectivamente en serie uno con el otro entre dichos primero y segundo conductores, dichos medios interruptores teniendo contactos de interruptor movibles entre una posición cerrada para completar un circuito y una posición abierta para interrumpir el circuito; y un circuito de derivación conectado en paralelo con dicho circuito interruptor entre dichos primero y segundo conductores e incluyendo medios de derivación de corriente normalmente no conductores para mantener normalmente una impedencia relativamente alta en dicho circuito de derivación, que es más alta que la impedencia de dicho circuito interruptor para que la corriente fluya normalmente a tráves de dicho circuito interruptor, dichos medios de derivación de corriente normalmente no conductores haciéndose conductores en respuesta a la aplicación de un voltaje predeterminado, dicho resistor de polarización cooperando con dichos medios de derivación de corriente para polarizar dichos medios de derivación de corriente a conducción en respuesta a la presencia de una oleada de corriente en dicho circuito interruptor, para así formar una trayectoria de baja impendancia en dicho circuito de derivación y permitir que la oleada de corrientes fluya a través de dichos medios de derivación de corriente y derive dichos medios interruptores, protegiendo así los medios interruptores contra las oleadas de corriente.
