ABSTRACT:
A pressurized gas circuit breaker capable of having a breaker chamber dismantled therefrom without loss of dielectric gas comprises: a vertical insulating support (101); a intermediate structure (100) mounted on said support and at least two breaker chambers (1, 1') per phase. Said chambers are disposed in a V-configuration on said intermediate structure, and said support and said breaker chambers are filled with gas under pressure. The circuit breaker further comprises a control jack (32) situated at the bottom of the support, and means for transmitting motion from the jack to the chambers to operate circuit breaking means located therein. Said means for transmitting motion comprise: gas-tight guide tube means (2, 2') filled, in use, with gas under pressure and having a straight insulating portion (102) situated inside the vertical insulating support and curved portions (103) situated inside said intermediate structure and leading to respective ones of said breaker chambers. Control shaft means (42, 42') are mounted with a sliding fit inside said guide tube means, and have one end connected to said control jack, and other ends connected to respective ones of said breaker chambers. The portions (107) of said control shaft means that slide in the curved guide tube portions are flexible. Each breaker chamber is fitted with a respective sliding air-lock (see FIG. 2) capable at one end of sealing the breaker chamber and at another end of sealing the guide tube means. Said air-lock comprises two separable members one of which is made fast to the breaker chamber and the other of which is made fast to the guide tube means, and said control shaft means comprise coupling means located inside said air-lock to enable the control shaft means to be separated into a first portion connected to the breaker chamber and a second portion connected to the guide tube means.
