ABSTRACT:
Gas-blast circuit interrupter of the puffer type comprising sealed compressed-gas filled arc-extinguishing chambers and support insulators. The enclosures of the chambers and of the support insulator thereof are traversed by control rods which operate the contacts and which are assembled in situ through a door managed in a junction housing which secures the enclosures together and accomodates the confronting end portions of the rods. The junction housing is gastight and may be filled with the same gas as the enclosures so as to avoid pressure differentials across the seals causing leakage of gas. A fluid communication is established between the enclosures after mounting thereof on the junction housing.
