摘要： @ An improved switch for a high-voltage device in which ignition of a power cartridge moves an insulative piston located in a conductive member away therefrom and into a passageway in an insulative liner. The piston moves a contact through a passageway and away from the conductive member to break an electrical interconnection between the conductive member and the movable contact, thereby opening the switch. The switch includes an insulative housing engageably surrounding, holding and fixing the relative positions of the conductive member and the liner. An interiorly relieved extension is formed at and about one end of the liner, and an exteriorly relieved region is formed in and about one end of the conductive member, whereby the region may be telescoped into and conformally engage the inside of the extension so that the conductive member and liner partially overlap along a tortuous interface so as to increase the interrupting capability of the switch by enhancing the isolation between the power cartridge and the passageway.

摘要： electrical switch (10) includes an alternating series of first and second switch cells. Each first cell (64) includes a first conductive member (67) with a first bore (68) and a first insulative member (71) conformally located in the first bore and movable through the first bore. Each second cell (66) includes a second insulative member (72) with a second bore (73) and a second conductive member (74) conformally located in the second bore and movable through the second bore. The first and second bores have substantially the same cross-section. The cells are mounted end-to-end in the alternating series so that the bores align. Severable metallic members (76) electrically interconnect the second conductive body of each second cell to the first conductive body of both first cells adjacent to the second cell. The first insulative bodies and the second conductive bodies are simultaneously moved to simultaneously sever the metallic members. A plurality of arcs are thereby produced between the first and second conductive bodies of adjacent cells. Additional arcs may be produced by covering the first bore of the first conductive member and the second conductive member with insulative layers.

摘要： When the pyrotechnical cartridge or motor (5) is actuated by electrical ignition from its head (5c), it pushes back the insulating piston (3) which separates by shearing the intermediary connection portion (1b) of the destructible lead (1) and pushes it back into the bore (1e) with the rod (9) of which the conic end (9a) wedges into the plug (10) for forming brake. The fuse cartridges (13) cut off safely the circuit. Application to electric circuit shut off, for example under the effect of overcurrent detectors.

摘要： Die Erfindung betrifft ein Verfahren zum Löschen des Lichtbogens in Hochspannungs-Hochleistungsschaltem, bei dem zumindest zum Zeitpunkt der Trennung der Schaltkontakte (4) in der Schaltkammer (1) des Hochspannungs-Hochleistungsschalters mit höheren Drücken gearbeitet wird.
Zwecks Abschaltung des Stromes innerhalb einer Halbwelle ohne Wiederzündung sowie einer wesentlichen Erhöhung der pro Schaltkammer abzuschaltenden Spannung übernimmt daher ein zum Schaltzeitpunkt kurzzeitig erzeugtes, elektrisch gut leitendes Hochdruckplasma, das vorzugsweise ein Kompressionsplasma oder ein Stoßwellenplasma ist, in der Schaltkammer (1) den Strom beim Öffnen der Schalkontakte (4). wobei danach durch Entspannung des elektrisch gut leitenden Hochdruckplasmas das Schaltlichtbogenplasma wirksam gelöscht wird.

摘要： The present invention relates to an interrupter comprising a gas producer configured to produce a gas by burning a fuel; an actuator pin configured to be driven under pressure of the gas produced by the gas producer; and an electrical conductor configured to electrically connect two terminals of an external electric circuit. The electrical conductor includes a first terminal portion; a first separable portion connected to the first terminal portion; a second terminal portion electrically connected to the first terminal portion; and a second separable portion connected to the second terminal portion and electrically connected to the first separable portion in parallel. The first separable portion is configured to be cut off from the first terminal portion by the actuator pin driven. The second separable portion is configured to be cut off from the second terminal portion by the actuator pin driven. A first timing when the first separable portion starts to be cut off from the first terminal portion is earlier than a second timing when the second separable portion starts to be cut off from the second terminal portion.

摘要： L'invention a pour objet un dispositif de protection électrique de type coupe-circuit comportant un boîtier (34), un système de sectionnement (38), positionné dans le boîtier (34), configuré pour occuper des états inactivé et activé correspondant respectivement aux états passant et non passant du dispositif de protection électrique (32) ainsi qu'un système de liaison (36) configuré pour occuper un état ouvert dans lequel il permet l'insertion d'un câble électrique (30) et un deuxième état fermé dans lequel il entoure le câble électrique (30), le système de liaison (36) et le système de sectionnement (38) étant agencés de manière à ce que, lorsque le système de liaison (36) est à l'état fermé, le système de sectionnement (38) sectionne le câble électrique (30) lors d'un passage de l'état inactivé à l'état activé.
Cette solution permet de conserver un câble électrique continu. En l'absence de connexion électrique, les risques d'échauffement et de déconnexion sont supprimés.
