Abstract
La presente descripción se refiere a un sistema de contacto de un interruptor de circuito y un interruptor de circuito. El sistema de contacto de un interruptor de circuito comprende: un soporte de contacto; un eje de soporte rotativo; una barra colectora una pluralidad de grupos de láminas conductoras, cada grupo de láminas conductoras que comprende dos o tres láminas conductoras, cada una provista de una lámina conductora provista de un contacto, y la pluralidad de grupos de láminas conductoras dispuestas en paralelo y soportadas de manera giratoria en el soporte de contacto por medio del dispositivo giratorio eje de soporte, de modo que la pluralidad de contactos forme una superficie de contacto que pueda entrar en contacto con un conductor externo para lograr la conducción eléctrica; y un miembro de conexión flexible, dos extremos de los cuales están conectados eléctricamente respectivamente con la pluralidad de láminas conductoras y la barra colectora. Se forma un primer espacio entre dos grupos de láminas conductoras adyacentes, se forma un segundo espacio entre dos láminas conductoras adyacentes en cada uno de los grupos de láminas conductores, y el primer espacio es más grande que el segundo espacio; los contactos en las láminas conductoras en dos lados del grupo de láminas conductoras están dispuestos distantes entre sí y desviados en la dirección de disposición de las láminas conductoras. Se evita una presión de contacto entre las láminas conductoras y el conductor externo debido a la soldadura por fusión sobrecalentada de los contactos. (Figura para el Resumen: Figura 2).The present description refers to a contact system of a circuit breaker and a circuit breaker. The contact system of a circuit breaker comprises: a contact holder; a rotary support shaft; a bus bar a plurality of groups of conductive sheets, each group of conductive sheets comprising two or three conductive sheets, each provided with a conductive sheet provided with a contact, and the plurality of groups of conductive sheets arranged in parallel and supported by rotatably on the contact support by means of the support shaft rotating device, so that the plurality of contacts form a contact surface that can come into contact with an external conductor to achieve electrical conduction; and a flexible connecting member, two ends of which are electrically connected respectively to the plurality of conductive foils and the bus bar. A first space is formed between two groups of adjacent conductive sheets, a second space is formed between two adjacent conductive sheets in each of the groups of conductive sheets, and the first space is larger than the second space; the contacts on the conductive foils on two sides of the group of conductive foils are arranged spaced from each other and offset in the direction of arrangement of the conductive foils. A contact pressure between the conductive foils and the outer conductor is avoided due to overheated fusion welding of the contacts. (Figure for Summary: Figure 2).
