The gas insulated electrical gear comprises at least one tank (2, 2A, 2B) which is filled with a dielectric gas and which is provided with a rupture disk (1) which ruptures in the event of the dielectric gas in the tank reaching an excessive pressure so as to allow the gas to be exhausted from the tank. The rupture disk is protected against attack from the environment outside the tank by being placed inside the enclosed cabinet (3) having an atmosphere in which temperature and humidity are controlled. The cabinet can be the low voltage and/or mechanical control supporting cabinet fitted to said electrical gear.
L'appareillage électrique à isolation gazeuse comprend au moins une cuve (2,2A,2B) qui est remplie d'un gaz diélectrique et qui est munie d'un disque de rupture (1) qui se rompt en cas de surpression du gaz diélectrique dans la cuve pour permettre l'évacuation du gaz vers l'extérieur de la cuve. Le disque de rupture est protégé contre les agressions de l'environnement extérieur à la cuve en étant disposé à l'intérieur du coffret (3) cloisonné à atmosphère dont la température et d'hygrométrie sont contrôlées. Ce coffret peut être le coffret basse tension et/ou support de commande mécanique équipant ledit appareillage électrique.
