Abstract

L'invention concerne un agencement de refroidissement d'un dispositif de commutation électrique tel qu'un disjoncteur (3) et/ou un sectionneur installé dans une enveloppe (2), cet agencement comprenant un conduit de refroidissement (11) électriquement isolant formant cheminée qui est monté à l'intérieur de l'enveloppe (2) de manière étanche en comportant deux ouvertures (13, 16) situées à deux hauteurs différentes et débouchant chacune hors de l'enveloppe (2). Un caloduc (7) électriquement conducteur traverse la paroi du conduit de refroidissement (11) pour comporter une portion de dissipation thermique (9) située dans ce conduit (11), ce caloduc (7) comprend une première extrémité (8) thermiquement couplée à une partie (6) à refroidir du dispositif de commutation (3) et une seconde extrémité située à l'intérieur du conduit (11) et présentant une forme bombée (22) pour éviter un amorçage d'arc électrique entre cette seconde extrémité (22) et l'enveloppe (2).The invention relates to a cooling arrangement for an electrical switching device such as a circuit breaker (3) and / or a disconnector installed in an enclosure (2), this arrangement comprising an electrically insulating cooling duct (11) forming a chimney. which is mounted inside the casing (2) in a sealed manner comprising two openings (13, 16) located at two different heights and each opening out of the casing (2). An electrically conductive heat pipe (7) passes through the wall of the cooling pipe (11) to include a heat dissipation portion (9) located in this pipe (11), this heat pipe (7) comprises a first end (8) thermally coupled to a part (6) to be cooled of the switching device (3) and a second end located inside the duct (11) and having a convex shape (22) to prevent an electric arc starting between this second end (22) ) and the envelope (2).
