    摘要: An interruption switch is provided for interrupting high currents at high voltages, with a casing, which surrounds a contact unit defining the current path through the interruption switch which has a first and second connection contact and a separation region. The contact unit is formed such that a current can be supplied to it via the first connection contact and can be discharged therefrom via the second connection contact, or vice versa. The separation region is formed such that, when it is separated, the current path between the first connection contact and the second connection contact is interrupted. The separation region is arranged inside a reaction chamber. A coating with a reactive material is present in the reaction chamber. The reactive material is designed such that under the influence of an electric arc it attenuates or extinguishes the electric arc.

    摘要: A pyrotechnic drive device includes a housing (3) provided with a combustion chamber (5) having pyrotechnic material (15) as well as an activation device (13). The combustion chamber is delimited at least in an initial state on all sides by combustion chamber walls (3, 7, 13, 17, 33, 35) formed in at least one partial region by respective pressure-receiving surface or respective pressure-receiving element (17, 35). Each pressure-receiving impact of a pressure-receiving element (17, 35) is impacted after the activation of the pyrotechnic material (15) in such a way by the gas pressure generated in this manner that the pressure-receiving element (17, 35) is moved and/or deformed (17, 35) and/or a mechanical impulse is thus transmitted via the pressure-receiving element (17, 35) to an element to be driven (19) so that a connected substance (25) is transmitted. The residual volume of the combustion chamber (5), in which no pyrotechnic material (15) is provided in the initial state, is filled with a liquid, a gel-like or pasty filling material (21), and/or a soft, rubber-like material.

    摘要: The present invention relates to a quick circuit breaker, that is, a switch with which an electrical circuit can be disconnected particularly quickly. Such switches are occasionally also referred to as pyrotechnic disconnect devices or as electrical interrupting switching elements. In particular, it is a quick circuit breaker (10) which comprises a current supply contact and a current discharge contact which are connected by a conductor (20) and in which the conductor (20) is guided through a separation chamber (12) and an expansion vessel (18) being provided in the separation chamber (12), the expansion vessel (18) being able to be expanded by an explosive charge. It is further about a method for emergency disconnection of a circuit.

    摘要: A switch (10), particularly a disconnecting switch (10) for high direct currents and alternating currents at high voltages, can be transferred from a conducting position into a disconnecting position. The switch (10) is includes a housing (12), a first contact (28), a second contact (30), a switching piston (24) guided by the housing (12) with a connecting element (22), which establishes an electrical connection in the connecting position between the first contact (28) and the second contact (30). The housing (12) defines an interior space surrounding the connecting element (22). The connecting element (22) extends at least partially in the interior space (18) and is filled with an insulating medium (20), and the switch is designed such that a mechanical movement of the switching piston (24) transfers the switch (10) from the connecting position into the disconnecting position. The switching piston (24) mechanically impacts the connecting element (22) such that the electrical connection between the first contact (28) and the second contact (30) is interrupted in at least one disconnecting location.

    摘要: An electrical interruption switch having a casing which surrounds a contact unit which defines the path of the current through the interruption switch, and having a propellant charge having a gas-generating activatable material. The contact unit has a first and a second connection contacts, an upsetting region, a separation region and a sabot. An extinguishing agent is provided in such a way that the motion of the sabot and/or the upsetting of the upsetting region reduces the volume for receiving the extinguishing agent in such a way that the extinguishing agent is injected through at least one discharge channel that connects the volume for receiving the extinguishing agent to the chamber in which the separation region is located, in order to extinguish or to prevent the formation of an electric arc between the ends of the separation region.
