Abstract

uma câmara autoenergizada de extinção de arco com um efeito de expansão térmica melhorada, que compreende um contato de arco móvel (4), um cilindro isolante (8), uma base de contato estacionário (1) disposto em uma extremidade superior do cilindro isolante (8) para montar um contato de arco superior (9) e um anel de arco superior (7) e uma base de contato de arco móvel (6) disposto em uma extremidade inferior do cilindro isolante (8) para montar um anel de arco inferior (5) e um contato de arco inferior (3). uma câmara de expansão térmica (2) formada dentro do cilindro isolante (8). as fraturas de uma câmara de extinção de arco são formadas em duas extremidades do cilindro isolante (8). o contato de arco móvel (4) se estende através do cilindro isolante (8), do anel de arco superior (7) e do anel de arco inferior (5) e está em contato com o contato de arco superior com contato de arco superior (9) e contato de arco inferior (3) em uma posição de ligação. no que diz respeito ao anel de ataque de arco superior (7) e ao anel de arco inferior (5) distribuído em duas extremidades de uma fratura, uma superfície de ataque de arco superior (121) e uma superfície de arco inferior (122) são formados respectivamente em superfícies adjacentes em uma direção de fratura. a superfície de ataque de arco superior (121) e/ou a superfície de ataque de arco inferior (122) estão dispostas radialmente com uma pluralidade de fendas de penetração. as aberturas de fendas (101) das fendas de penetração estão conectadas a anéis internos dos anéis de ataque de arco (5, 7) onde estão localizadas. as caudas de fenda (102) das fendas de penetração estão conectadas a bordas de anéis externos dos anéis de ataque de arco (5, 7) onde estão localizadas. as linhas retas de conexão entre as aberturas de fenda (101) e as caudas de fenda (102) não passam pelos centros dos anéis de ataque de arco (5, 7) onde os mesmos estão localizados e as direções de inclinação das linhas retas de conexão são consistentes.a self-energizing arc extinguishing chamber having an enhanced thermal expansion effect comprising a movable arc contact (4), an insulating cylinder (8), a stationary contact base (1) disposed at an upper end of the insulating cylinder ( 8) for mounting an upper arc contact (9) and an upper arc ring (7) and a movable arc contact base (6) disposed at a lower end of the insulating cylinder (8) for mounting a lower arc ring (5) and a lower arc contact (3). a thermal expansion chamber (2) formed within the insulating cylinder (8). Fractures of an arc extinction chamber are formed at two ends of the insulating cylinder (8). the moving arc contact (4) extends through the insulating cylinder (8), the upper arc ring (7) and the lower arc ring (5) and is in contact with the upper arc contact with upper arc contact (9) and lower arc contact (3) in a bonding position. with respect to the upper arch lead ring (7) and the lower arch ring (5) distributed at two ends of a fracture, an upper arch lead surface (121) and a lower arch surface (122) they are formed respectively on adjacent surfaces in a fracture direction. the upper arc strike surface (121) and / or the lower arc strike surface (122) are arranged radially with a plurality of penetration slots. The slot openings (101) of the penetration slots are connected to the inner rings of the arc attack rings (5, 7) where they are located. the slot tails (102) of the penetration slots are connected to the outer ring edges of the arc strike rings (5, 7) where they are located. the straight lines connecting the slit openings (101) and the slit tails (102) do not pass through the centers of the arc strike rings (5, 7) where they are located and the inclination directions of the straight lines of connection are consistent.
