摘要： An electric gas-switch includes a switching chamber that is divided by a partition into an arc chamber and an additional chamber with a central pin being located within the arc chamber. The pin is embraced at least partially by a stationary switch part which is surrounded by a coil through which is flowing a cut-off current. One end of the coil is connected with an annular intermediate electrode which surrounds the central pin at a distance within the region of its free end. In an on position the central pin is embraced, at least at its free end, by the movable switch part that is designed in the form of a nozzle.

摘要： A separable contact structure is provided for a high-voltage compressed-gas circuit interrupter involving at least one of the contacts being tubular to provide a gas flow therethrough, and having a liner component therein. To facilitate movement of the terminal end of the arc, a relatively thin tubular member is inserted interiorly of the hollow contact, and, by electrically connecting the same to the inner anterior end of the hollow contact, the magnetic field situation is such that the terminal end of the arc is encouraged to move axially along the relatively thin tubular liner member to thereby effect considerable elongation of the established arc, and thereby to effect the extinction of the same by a more effective gas flow condition. As a further extension of this same concept, a cooperable tubular contact structure may be provided, through which gas also exhausts, and a similar relatively thin tubular liner member may also be associated therewith to act in a similar manner.

摘要： In a high-voltage circuit breaker having two arcing contacts arranged coaxially relative to one another and having an insulating nozzle which in the closed state is blocked by a first arcing contact the first arcing contact has a shaft having a greater diameter and an end element having a smaller diameter, the shaft blocking a through-channel of the insulating body. The through-channel is cylindrical along a length that is smaller than the length of the end element. As a result, the extinguishing gas starts to flow when the end element is pulled back into the through-channel.

摘要： A contact zone (1) of a quenching chamber which is arranged rotationally symmetrical about a central axis (2) and is filled with an insulating medium, having at least two stationary consumable contacts which are in the form of contact rings (4, 15) and which, when the quenching chamber is closed, are electrically conductively connected by means of a bridging contact which is arranged centrally and can move axially. The mutually facing end surfaces of the consumable contacts are partially covered by electrically insulating covers (11, 22). The aim is to provide insulating covers which are designed to have good dielectric characteristics and are easy to install. This is achieved in that a wedge-shaped annular gap (11a, 22a) which is open in the radial direction and originates from a contact-making edge (10, 21), of the cover (11, 22) is provided between a contact-making surface (7, 18) and an insulating cover (11, 22) and in that the edge (10, 21) is dielectrically shielded by means of an annular bead (8, 19) which projects beyond the contact-making surface (7, 18).

摘要： A high voltage, high power circuit interrupter uses liquid SF.sub.6 in a puffer type arrangement. The cooperating contacts are surrounded by a nozzle and an upstream and a downstream piston, which are moved by a constant force-operating mechanism, move liquid SF.sub.6 between the cooperating contacts when they separate, in order to interrupt the arc between the contacts. The interrupter requires a relatively low volume of SF.sub.6 and a constant pressure is generated in the liquid during interruption. The interrupter ratings are adjusted by varying the differential pressure across the nozzle, and by changing the base-operating pressure.
摘要翻译：高压，高功率断路器使用液体SF6，采用吹气式排列。配合的触点被喷嘴和由恒定的力操作机构移动的上游和下游活塞包围，当它们分离时，液体SF6在配合的触点之间移动，以便中断触点之间的电弧。中断器需要相对较小的SF6体积，并且在中断期间在液体中产生恒定的压力。通过改变喷嘴上的差压以及改变基准工作压力来调节断路器额定值。
