Abstract

Inventia se refera la un întrerupator de circuit cu gaz izolator si în special la un întrerupator de circuit de înalta tensiune cu gaz izolator ce are o duza îmbunatatita pentru dirijarea curentului de gaz. întrerupatorul de circuit cu gaz izolator conform inventiei este prevazut cu un piston, un cilindru de actionare mobil fata de piston pentru a comprima gazul, ansamblul conectat mobil cooperabil cu ansamblul contact fix fiind sprijinit de cilindrul de actionare fiind dispusa imediat lînga contactul de descarcare prin arc mobil, suprafata interioara a duzei fiind adaptata pentru dirijarea curentului în interior de gaz izolator comprimat între piston si cilindrul de actionare în arcul stabilit între contactele de descarcare prin arc mobil si în timpul operatiei de deschidere, suprafata exterioara a duzei fiind astfel conturata si adaptata încît sa dirijeze curentul de gaz comprimat care a trecut prin arc în afara contactului principal mobil.
