摘要： A contact arrangement has a longitudinal axis and includes a first contact group with a first contact and a second contact and a second contact group with a third contact and a fourth contact. The first contact interacts electrically and mechanically with the third contact, and/or the second contact interacts electrically and mechanically with the fourth contact, for closing and opening the contact arrangement. At least one mechanical coupling is provided for transmitting an actuation force to the second contact group and thereby moving the second contact group. The at least one mechanical coupling is adapted to move the third and the fourth contact in such a way that their speeds differ along at least a portion of a travel path of the third contact or along at least a portion of a travel path of the fourth contact.

摘要： A power switch operating mechanism comprises: a series of external permanent magnets, a series of internal permanent magnets, an internal pipe, an external pipe, a three-phase coil, an output ring and a power supply lead. In the series of external permanent magnets, the magnets are juxtaposed in such a way that their magnetic poles are rotated by a maximum of 90° in each case. In the series of internal permanent magnets, the magnetic poles have magnetization vector radial components that are in the same direction as that of the series of external permanent magnets and magnetization vector, axial components that are in the opposite direction to that of the series of external permanent magnets. The series of external permanent magnets and the series of internal permanent magnets are fixed so that their magnetization vector radial components are in the same direction. The three-phase coil is interposed with a fixed clearance between the series of external permanent magnets and the series of internal permanent magnets.

摘要： A puffer type gas circuit breaker has a piston, which is connected with a center shaft via a link mechanism. At an initial stage of an interruption operation, the link mechanism drives a puffer cylinder and the piston both in an interruption direction while maintaining an almost constant distance therebetween. Even when a pressure rise occurs in a compression chamber by the heat of an arc generated in accordance with opening between a fixed arc contact and a movable arc contact, the pressure rise does not become an operation counterforce to an operator. At a final stage of the interruption operation where the fixed arc contact is removed from a throat of an insulating nozzle, the link mechanism drives the piston in an almost stopped status.

摘要： The heavy-duty circuit breaker can be filled with a quenching gas and contains a first moveable arcing contact piece and a second moveable arcing contact piece as well as a drive for driving the first arcing contact piece and an auxiliary drive for driving the second arcing contact piece. An arc may burn between the arcing contact pieces. The heavy-duty circuit breaker has a heating chamber for temporarily storing quenching gas heated by the arc and an insulating nozzle, which has a throat for guiding a quenching gas flow, which throat is connected to the heating chamber by means of a channel. The throat can be blocked at least partially by one of the two arcing contact pieces, which is referred to as the blocking contact piece. The auxiliary drive is designed such that, during an opening operation, a movement direction reversal of the second arcing contact piece from a movement in opposite directions to a movement in the same direction of the two arcing contact pieces takes place, if the throat is no longer at least partially blocked by the blocking contact piece. Advantageously, the gear is a gear which is driven by the drive.

摘要： The present invention relates to a circuit-breaker including, inside a casing filled with a dielectric gas, a first arcing contact connected to a first terminal, and a second arcing contact having the same longitudinal axis as the first contact. The second arcing contact is connected to a second terminal, is mounted to move axially in a fixed cylinder, and co-operates with a moving piston to form a compression chamber. The circuit-breaker further includes a mechanism for driving the piston in a direction that is opposite to the direction in which the second contact is displaced. The driving mechanism acts during a first portion of the displacement of the moving contact from the closed position to the open position the circuit-breaker also includes a mechanism for constraining the piston to move with the moving contact during a second portion of the same displacement of the moving contact.

摘要： A puffer type circuit breaker is provided with a pump means consisting of a piston and a cylinder for producing a blast of arc-extinguishing gas. The piston is joined to one contact of the circuit breaker and the cylinder to the other contact. Both contacts are connected to an operating device which is adapted, during the first part of a breaking operation, to move the contacts in opposite directions away from each other, whereupon one contact and the piston joined thereto are returned to the initial position.
