摘要： The compressed-gas cutout (10) according to the invention comprises a first contact (14) and a second contact (18), which are displaceable relative to each other along a longitudinal axis (A). A blow volume (54, 52, 68) is provided around the first contact (14). Said blow volume (54, 52, 68) is connected via a gas channel (44) to an electric arc zone (40) in order to blow at an electric arc produced when disconnecting the first contact (14) from the second contact (18). The blow volume (54, 52, 68) is delimited radially on the outside by a disconnecting element (30), which disconnects the blow volume (54, 52, 68) from a low-pressure chamber (72). In the radial direction, a flow opening (64, 66, 68) enabling gas exchange leads from the low-pressure chamber (72) into the blow volume (54, 52, 68).

摘要： A contact arrangement has a longitudinal axis (z) and comprises at least a first contact (4a) and at least a second contact (4b) interacting electrically and mechanically with each other for closing and opening the contact arrangement. The first contact (4a) is surrounded by a protecting cover element (2) in such a way that a contacting extremity of the first contact (4a) protrudes beyond the cover element (2). The first contact (4a) and the cover element (2) are arranged with respect to one another in such a way that a gap (7) is provided between them along at least a portion of their elongation, wherein the gap (7) has a first opening (10) towards a first volume (15) surrounding the first contact (4a). The cover element (2) comprises at least one chamber (9) connected at least to the gap (2).

摘要： A simplified construction of a gas-insulated high-power circuit breaker with a saving of components is achieved by at least one hole and at least one leaf spring, which is fastened on one side and is elastically bendable in dependence upon the pressure of the insulating gas in the compression volume, being formed in a valve plate of the valve. The bendable spring closes off the hole when the circuit breaker closes and opens it when the circuit breaker opens as soon as the pressure of the compressed insulating gas in the compression volume exceeds the value of the gas pressure in the low-pressure chamber by at least two bar.
