Abstract

Mejoras introducidas en el objeto de la Patente principal nº 424.599, por: "Unión entre instalación bajo envolvente metálica aislada por un gas a presión y un transformador aislado por un líquido dieléctrico", teniendo esta unión una cámara intermedia que separara el volumen interno del transformador del de la instalación, estando el volumen interno de la cámara intermedia llena de un líquido dieléctrico a pequeña presión y delimitado por dos superficies, una interna constituida por la superficie exterior de un paso condensador, la otra externa formada en su mayor parte por una pared aislante cónica que corona el paso condensador y penetra en la envolvente metálica, caracterizadas porque la pared aislante cónica tiene en su base un collarín externo que presenta dos superficies anulares concéntricas, poniéndose una en contacto con la envolvente metálica de la instalación y definiendo un plano de junta entre el volumen interno de la instalación a presión de gas y la atmósfera, y definiendo laotra con otra pieza un plano de junta entre el volumen interno de la cámara intermedia lleno de líquido dieléctrico y la atmósfera.
