Abstract
(EN) A gas-insulated switch apparatus (1) is provided with, inside a pressure tank (4): a vacuum valve (11) that has, in a vacuum, a movable contact (14) provided on one side of a movable conductor (12) and a fixed contact (15) provided on a fixed conductor (13); an insulating rod (23) that is connected to the other side of the movable conductor (12) led from the vacuum valve (11) via bellows (16); an operation rod (24) that connects the insulating rod (23) to an operation device (5) external to the pressure tank (4); an airtight container (26) in which the insulating rod (23), the other side of the movable conductor (12), and the operation rod (24) are housed; and an intermediate pressure chamber (37) formed by connection between the bellows (16) and the inner space of the airtight container (26), wherein a sliding contact member (32) is provided on the other side of the movable conductor (12), the sliding contact member (32) is connected, via the airtight container (26), to a main circuit conductor (8) provided inside the pressure tank (4), and connection to the inside of the airtight container (26) is achieved by a connection portion provided between the airtight container (26) and the sliding contact member (32).
(FR) La présente invention concerne un appareil de commutation à isolation gazeuse (1) qui comprend, à l'intérieur d'un réservoir de pression (4) : une soupape à vide (11) qui a, sous vide, un contact mobile (14) disposé sur un côté d'un conducteur mobile (12) et un contact fixe (15) disposé sur un conducteur fixe (13) ; une tige isolante (23) qui est reliée à l'autre côté du conducteur mobile (12) conduit à partir de la soupape à vide (11) par l'intermédiaire d'un soufflet (16) ; une tige d'actionnement (24) qui relie la tige isolante (23) à un dispositif d'actionnement (5) externe au réservoir de pression (4) ; un récipient étanche à l'air (26) dans lequel la tige isolante (23), l'autre côté du conducteur mobile (12), et la tige d'actionnement (24) sont logés ; et une chambre de pression intermédiaire (37) formée par liaison entre le soufflet (16) et l'espace intérieur du récipient étanche à l'air (26), un élément de contact coulissant (32) étant disposé sur l'autre côté du conducteur mobile (12), l'élément de contact coulissant (32) étant relié, par l'intermédiaire du récipient étanche à l'air (26), à un conducteur de circuit principal (8) disposé à l'intérieur du réservoir de pression (4), et une connexion à l'intérieur du récipient étanche à l'air (26) étant obtenue par une partie de raccordement disposée entre le récipient étanche à l'air (26) et l'élément de contact coulissant (32).
(JA) 圧力タンク(4)の内部に、可動導体(12)の一方の側に設けられた可動接点(14)と固定導体(13)に設けられた固定接点(15)を真空中に有する真空バルブ(11)と、真空バルブ(11)からベローズ(16)を介して引き出された可動導体(12)の他方の側と連結された絶縁ロッド(23)と、圧力タンク(4)外部の操作装置(5)と絶縁ロッド(23)とを接続する操作ロッド(24)と、絶縁ロッド(23)、可動導体(12)の他方の側、操作ロッド(24)が収納された気密容器(26)と、ベローズ(16)と気密容器(26)の内部空間とが連通して形成された中間圧力室(37)とを備えたガス絶縁開閉装置(1)であって、可動導体(12)の他方の側に摺動接触部材(32)が設けられ、摺動接触部材(32)は圧力タンク(4)の内部に設けられた主回路導体(8)と気密容器(26)を介して接続され、気密容器(26)との間に設けられた連通部により気密容器(26)の内部は連通される。
