摘要： A relief valve for discharging a dielectric gas between two volumes (V1, V2) of a high-voltage or medium-voltage interrupting chamber. There is used as a closure member a flexible metal blade secured to the body, the closure member therefore being opened by deformation of the flexible blade from a closed position (FIG. 1) in which it is pressed against a closure member seat formed in the body to a fully open position in which it fits closely against a stop member secured to the valve body while remaining within its elastic limit, the open passage for the gas being open in this fully open position (FIG. 1A) and the return of the blade from its fully open position to its closed position being possible because of its flexibility.

摘要： The present invention relates to an arc-quenching device for circuit breakers having double-break contacts for use in low-voltage distribution systems. Provided around a prechamber (41) is a magnetic shield (91) for the purpose of intensifying the magnetic blowing action on an arc formed between the arc guide rails (51, 61) of the prechamber. In addition, a blowing loop (81) is inserted in the arc-quenching circuit and extends in sections parallel to an arc guide rail (61). Prechamber insulation having a bulge constricting the arc area likewise serves the purpose of optimizing the arc run.

摘要： Extending between a fixed tulip contact (1) and a slide tulip (4) is an arcing chamber (5) which is occupied in the closed position by a movable contact pin (3) which fills up both an exhaust (9) surrounded by the slide tulip (4) and a blowout opening (7) which is surrounded by the tulip contact (1) and connects the arcing chamber (5) to a pressure chamber (6). The arcing chamber (5) is surrounded by an annular heating volume (13) open toward the same. Arranged in the pressure chamber (6) is a charge (10) of explosive which is for the most part converted within approximately 10-30 ms after ignition to extinguishing gas, preferably predominantly nitrogen, the gas pressure moving the contact pin (3) toward the open position. After clearance of the blowout opening (7) and the exhaust (9), the arc drawn between the contact pin (3) and tulip contact (1) is blown out, something which is supported by the pressure buildup, to which the arc contributes, in the heating volume (13). The pressure chamber with the charge can also surround the arcing chamber in an annular fashion. In this case, it is also possible to support the opening movement by the explosion pressure, for example, via pistons.
