Abstract
(EN)
An arc extinction apparatus according to an embodiment of the present invention comprises a chamber unit, a division unit, a filter unit, and a cover unit. A discharge port is formed in the chamber unit such that a fluid in the chamber unit is discharged to the outside. An insertion groove is provided on inner surfaces of the chamber unit that face each other. The division unit is coupled to the inside of the chamber unit. In addition, the division unit divides a path of the fluid discharged through the discharge port into multiple paths. The filter unit is disposed in the discharge port and filters out at least one predetermined material from the fluid passing through the discharge port. The cover unit comprises a plurality of exhaust pipes and is coupled to the discharge port from the outside of the filter unit. Furthermore, the division unit comprises a grid and an insulation cap. Side portions of each of a plurality of grids at either side thereof are inserted into the insertion groove. The insulation cap is coupled to upper ends of the plurality of grids and comprises a vent pipe which is open between the plurality of grids.

Un appareil d'extinction d'arc selon un mode de réalisation de la présente invention comprend : une unité de chambre; une unité de division; une unité de filtre et une unité de couvercle. Un orifice de décharge est formé dans l'unité de chambre de telle sorte qu'un fluide dans l'unité de chambre est déchargé vers l'extérieur. Une rainure d'insertion est disposée sur des surfaces internes de l'unité de chambre qui se font face. L'unité de division est couplée à l'intérieur de l'unité de chambre. De plus, l'unité de division divise un trajet du fluide déchargé à travers l'orifice de décharge en de multiples trajets. L'unité de filtre est disposée dans l'orifice de décharge et filtre au moins un matériau prédéterminé à partir du fluide passant à travers l'orifice de décharge. L'unité de couvercle comprend une pluralité de tuyaux d'échappement et est couplée à l'orifice de décharge depuis l'extérieur de l'unité de filtre. En outre, l'unité de division comprend une grille et un capuchon isolant. Des parties latérales de chacune d'une pluralité de grilles de chaque côté de celles-ci sont insérées dans la rainure d'insertion. Le capuchon isolant est couplé aux extrémités supérieures de la pluralité de grilles et comprend un tuyau d'aération qui est ouvert entre la pluralité de grilles.
