Abstract

Interruptor eléctrico de potencia de reducido volumen de líquido, caracterizado por comprender una cámara de extinción, con un recinto de expansión por encima de la cámara de extinción con un contacto fijo situado en la parte superior de la cámara de extinción, con una varilla de contacto que al desconectar se desplaza hacia abajo, la cual del recinto inferior de la cámara de extinción impulsa líquido extintor; y como mínimo tiene un elemento de válvula para unir el recinto inferior de la cámara de extinción, con el recinto de expansión al sobrepasarse una determinada presión en la parte inferior de la cámara de extinción, siendo el camino de unión entre los dos recintos lateral si la cámara de extinción; figurando en el interior del tubo aislante discos fijados a unas distancias y que guían la varilla a través de taladros, teniendo estos discos distintos juegos respecto a la varilla, habiendo un disco con menor juego y los discos van aumentando su juego respecto a la varilla deuna forma progresiva conforme se van acercando a los extremos de la cámara de extinción.
