Abstract

Un interruptor de circuitos de alta tensión que utiliza un fluido dieléctrico, reduciendo sustancialmente el arco resultante formado por la interrupción el flujo de dicho fluido causando la extinción de dicho arco cerca de un valor cero de la corriente un mínimo de baja presión incipiente, comprendiendo dicho interruptor contactos móviles y fijos dispuestos en al menos un recinto parcialmente confinado, caracterizado por medios para introducir dicho fluido dieléctrico en dicho recinto a una presión alta inicial predeterminada y mantener sustancialmente dicha presión a lo largo de un intervalo de tiempo predeterminado, medios de almacenamiento de energía sensibles a dicho fluido de alta presión y a los cambios en dicho flujo de fluido para suavizar la presión resultante de dicho fluido por reducción de dicho máximo de presión y aumento de dicho mínimo de presión, y porque dicho recinto proporciona un camino de flujo primario para dicho fluido en una boquilla formada por la separación de dicho contacto móvil con respecto a dicho contacto fijo y una camino de flujo secundario formado al menos parcialmente por dicho contacto fijo.
