摘要： The present invention relates to a medium- or high-tension circuit breaking having abutting arcing contacts and comprising a casing filled with a gas having good dielectric properties and containing a stationary first abutting contact and moving equipment including a first tube capable of being displaced by a drive rod and a semi-moving tubular second abutting contact. The annular end of the first tube carries a ring of contact arms that slide on the first abutting contact and that carry respective arcing contact blocks at their ends and respective permanent contact swellings proximate to the arcing contact blocks. A circuit breaker is thus provided which withstands the effects of arcing particularly well.

摘要： A circuit breaker includes an insulating casing, a stationary main contact, a stationary arcing contact. A moving main contact and a moving arcing contact constituted by a tube define a blast cylinder co-operating with a first fixed piston. A second piston secured to a moving assembly includes the tube and slides in a second stationary cylinder. The volume between the two cylinders is put into communication with a volume adjacent to the casing or with a volume inside the tube via openings. An inertial ring selectively closes off the openings by moving between first and second extreme positions, the first position being one in which the openings are open and corresponding to a rest position for the moving assembly, and the second position being one in which the openings are closed.

摘要： In a gas-blast circuit breaker, compressed gas is directed through a movable contact maker into a blow-out space, the latter being delimited by a cylinder and a piston which is operatively associated with the movable contact maker. The piston comprises inlet openings which are releasably closed by means of a valve body. At a neck or collar of the piston there is displaceably mounted an actuating element, the latter being reciprocatingly movable between a lower first lock-in position and an upper second lock-in position. The actuating element comprises a nose or lug which, during the closing operation, abuts against an upper stop face or surface, whereby the actuating element is brought into the lower first lock-in position. The valve body thereby moves into the closed position thereof. Towards the end of the opening stroke, a shaft associated with the actuating element comes to bear upon a lower stop face or surface, so that the actuating element is brought back to the upper second lock-in position thereof, whereby the valve body is returned to and retained in its open position. The blow-out space is thus connected with the ambient space during the closing operation and again separated from the ambient space prior to the opening or tripping operation. The driving mechanism of the circuit breaker is assisted during the interruption of relatively high-amperage currents and no additional driving effort is required of the driving mechanism during the closing operation and the interruption of relatively low-amperage currents. The gas-blast circuit breaker thus gets by with a driving mechanism of relatively low operating power.

摘要： A gas blast circuit breaker comprises a cylindrical metal or insulative enclosure filled with pressurized insulative gas, a fixed arc contact and a mobile assembly coupled to an operating member comprising a gas blast cylinder associated with a gas blast nozzle and cooperating with a piston, and a mobile arc contact carried by a tubular member inside the gas blast cylinder. The inside wall of the tubular member comprises a bottleneck whose cross-section is less than the inside cross-section of the tubular member and coaxial therewith. The minimum cross-section of the bottleneck has a diameter less than or equal to the diameter of the inside cross-section of the mobile arc contact and equal to at least 0.75 times the diameter of the inside cross-section of the mobile arc contact. The operation of the circuit breaker is improved by increasing the gas pressure near the mobile arc contact by virtue of a particularly simple and low-cost arrangement.

摘要： A gas-blast load-break switch comprises a pressure storage chamber for storing pressure of arc-extinguishing gas with arc energy generated by the disconnection between contacts, and a suction chamber including a piston which is moved in connection with the cut-off movement of the movable contact. A gas flowing device is provided such that the pressure raised by the arc energy is stored in the pressure storage chamber before communicating the pressure storage chamber and the suction chamber and a gas chamber formed on the opposite side of the piston from the suction chamber. The volume of the gas chamber is greater than that of the pressure storage chamber and the suction chamber, and the distance of piston movement in the suction chamber is longer than the contact length when the movable contact is thrown into the fixed contact.

摘要： A gas circuit breaker includes a pair of separable contact portions, a nozzle of an electrically insulating material surrounding the contact portions to guide a flow of gas, and a buffer chamber for compressing the gas upon a separating operation of the contact portions so as to supply the gas under the guidance of the insulating nozzle. The gas from the puffer chamber is exhausted through exhaust passages passing through a hollow portion of a movable one of the contactors. The exhaust passages are formed between the puffer chamber and the movable contactor. A blocking arrangement, during initial stage of the separating operation, closes the exhaust ports of the exhaust passages and subsequently opens the exhaust ports located on a downstream side of the gas flow. The blocking arrangement, of an electrically insulating material, is divided along an axial direction of the gas circuit breaker. Electrical insulating material of the blocking arrangement is fastened by springs from the exterior of the circuit breaker to reduce unnecessary gas flow from the puffer chamber through the blocking arrangement.
