摘要： 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.

摘要： The invention relates to a resistance switch-in device for switching in only when a circuit breaker closes, said switch-in device including a moving arcing contact in an interrupter chamber. The device is characterized in that the switch-in contacts (2 and 3, 32 and 33) are disposed in the interrupter chamber (1) of the circuit breaker and that since at least one (2,32,33) of said switch-in contacts is a moving contact, it moves on a path parallel to that of the moving arcing contact (5). The invention applies in particular to connecting a load to long-distance high-tension circuits that are unloaded.

摘要： A reciprocating rod bears a bridge which is movable on the rod with initial movement of the rod in a given direction completing closure of bridge carried moving contacts onto stationary contacts for inserting a resistance in a circuit during closure. Linkage between the rod and main contacts functions to subsequently close the main contacts of the cut-out switch, thereby shorting the resistor. Continued movement of the rod in a given direction subsequently causes the bridge borne contacts to move away from the stationary contacts, thereby opening the circuit through the resistors.
