Abstract (en)

[origin: US2017309425A1] An air circuit breaker includes two separable electrical contacts connected to electric current input and output terminals; and a chamber for quenching an electric arc, including a stack of splitter plates that are spaced apart from one another, and lateral walls placed on either side of the stack and including a thermosetting-resin impregnated polyamide woven and being devoid of glass fibres. The quenching chamber furthermore includes protective elements made of crosslinked polyamide, the elements being placed in junction zones between the lateral walls and holding plates, the protective elements covering corners of the splitter plates, which corners are adjacent to the lateral walls, so as to separate these corners of the splitter plates from the electrical contacts.

Abstract (fr)

Ce disjoncteur à coupure dans l'air comporte : - deux contacts électriques séparables raccordés à des terminaux d'entrée et de sortie d'un courant électrique ; - une chambre de coupure (18) d'un arc électrique, comportant un empilement (20) de plaques de séparation (22) espacées les unes des autres et des parois latérales (24) disposées de part et d'autre de l'empilement (20) et comportant un tissu polyamide imprégné de résine thermodurcissable et étant dépourvue de fibres de verre. La chambre de coupure (18) comporte en outre des éléments de protection (40) en polyamide réticulé placés au niveau de zones de jonction entre les parois latérales (24) et les plaques de maintien (22), les éléments de protection (40) recouvrant des coins (49) des plaques de séparation (22) adjacents aux parois latérales (24), de sorte à séparer ces coins (49) des plaques de séparation (22) des contacts électriques.
