    摘要: The electrical apparatus is located in a metal container filled with pressurized dielectric gas and comprises: an electrical conductor (1) with a longitudinal axis (X), the conductor being intended to hold a voltage and being placed inside the container (6); and two corona-shield caps (10, 12) partially surrounding the conductor (1), at least one of the corona-shield caps (10) comprising a hollow, electrically conductive body (14) having a longitudinal axis substantially coaxial with the axis of the case (6), said body (14) comprising an annular depression (22) in its external surface and holes (26) passing through said body (14), the holes being produced in the bottom of said depression. The holes (26) ensure that the dielectric gas can circulate between a zone internal to and a zone external to the corona-shield cap (10) by convective exchange.

    摘要: A switchgear according to the present invention includes a fixed contactor provided in a tank filled with insulating gas, and a movable contactor provided in the tank, the movable contactor being connected to and disconnected from the fixed contactor so as to move forward and backward. The switchgear includes an arc extinction member including a surrounding portion which is slidably connected to the outer circumferential surface of the movable contactor halfway in a movement range from a closed contact state to an open contact state and is formed so as to surround an arc space portion in a sealed manner, the surrounding portion being formed with a through hole through which the arc space communicates with the outside of the arc space.

    摘要: A gas-insulated low- or medium-voltage switch (1) for system voltages within 1 to 52 kV and for up to 2000 A rated current comprises first and second contacts (10, 20) being movable in relation to each other along an axis (2) of the switch and defining a quenching region (3) in which an arc is formed during a current breaking operation; and an arc-extinguishing system (30) for extinguishing the arc during the current breaking operation. The arc-extinguishing system (30) comprises a swirling device (50) configured for generating a subsonic swirl flow of a quenching gas onto the quenching region (3) during the current breaking operation.

    摘要: L' invention concerne une chambre de coupure de courant dans laquelle le soufflage est réalisé intégralement par l'intérieur d'un tube creux (30) qui porte l'un des contacts (3).
    Selon l'invention, on réalise un rétrécissement (304) de section S2 de passage du gaz de soufflage en amont de la partie contact (31) proprement dite de section S1 à laquelle est relié le tube creux (30) et une section S3 de passage plus large (305) entre les deux (304, 31), c'est-à-dire S2
    On évite ainsi de réaliser une zone de faible densité de gaz à proximité de la zone de contact proprement dite (31) qui est celle la plus exposée aux champs électrique après coupure.
    La chambre de coupure ainsi conçue présente une bonne tenue diélectrique à la tension transitoire de rétablissement (TTR).

    摘要: An interrupter unit of an electrical switching device has a flow-conducting body. Gases which are flowing away are guided by way of the flow-conducting body. The flow-conducting body is formed at least from a first and a second element, wherein a joint gap is formed between the two elements. The joint gap has a section, which is formed with a complementary shape between the two elements so as to form a labyrinth structure.

    摘要: L'intérieur des contacts (20,24) tubulaires d'un disjoncteur à autoexpansion et à gaz SF6 comporte des nervures de guidage (56,58) agencées pour s'opposer à tout écoulement gazeux tourbillonnaire à effet Vortex entre la première chambre de coupure (26) et la deuxième chambre d'expansion. La présence de ces nervures améliore la tenue diélectrique du disjoncteur, et empêche tout réamorçage de l'arc à l'intérieur des contacts.
