Abstract

Un interruptor de circuito eléctrico que utiliza un medio dieléctrico y que comprende medios de contacto estacionarios, una boquilla eléctrica y térmicamente aislante que tiene una garganta de boquilla y un contacto móvil normalmente insertado en dicha garganta de boquilla y en contacto eléctrico con dichos medios de contacto estacionarios, caracterizado por un cilindro aislado para contener dicho medio di eléctrico en estado líquido en todo momento y que tiene un extremo conectado a dicha boquilla y el otro extremo a un pistón de bomba, medios de almacenamiento de líquido para llenar dicho cilindro con dicho líquido a una velocidad predeterminada, y medios de válvula que regulan el paso a dicho cilindro y dicha boquilla, incluyendo dichos medios de válvula una abertura a través de una pared lateral de dicha boquilla, teniendo dicho cilindro dicho primer extremo conectado a dicha abertura, cerrando normalmente dicho contacto móvil dicha abertura de manera que, cuando se mueve, permite que dicho líquido fluya a través de dicha abertura y dicha garganta de boquilla, a fin de permitir que dicho pistón de bomba haga que dicho líquido fluya a través de dicha garganta de boquilla a una velocidad predeterminada.
