Abstract

a presente invenção refere-se a um interruptor e uma estrutura de exaustão do mesmo. o interruptor compreende um coletor de escape (101, 102, 103). o coletor de escape é alinhado com uma cauda de uma câmara de extinção de arco (106). um espaço de exaustão do coletor de escape é sobreposto com um dispositivo de ligação (401, 402) do interruptor. quando o dispositivo de ligação não está conectado, o dispositivo de ligação ocupa o espaço de exaustão. quando o dispositivo de ligação está conectado, o espaço de exaustão está desocupado. a estrutura de exaustão de interruptor utiliza um espaço desocupado do dispositivo de ligação, aumenta a quantidade de coletores de escape, expande o espaço de exaustão, aperfeiçoando, desse modo, significantemente, a capacidade de exaustão. a estrutura de exaustão é também provida com uma saliência de bloco (104) para corte de um arco. a saliência de bloco também serve como um suporte para a câmara de extinção de arco, evitando redução da capacidade de extinção de arco devido a uma alteração da câmara de extinção de arco causada por um impacto.the present invention relates to a switch and an exhaust structure thereof. the switch comprises an exhaust manifold (101, 102, 103). the exhaust manifold is aligned with a tail of an arc extinguishing chamber (106). an exhaust space of the exhaust manifold is overlaid with a switch connection device (401, 402). when the connecting device is not connected, the connecting device occupies the exhaust space. when the connecting device is connected, the exhaust space is unoccupied. the switch exhaust structure utilizes an unoccupied space of the connection device, increases the number of exhaust manifolds, expands the exhaust space, thereby significantly improving the exhaust capacity. the exhaust structure is also provided with a block protrusion (104) for cutting an arc. the block protrusion also serves as a support for the arc extinguishing chamber, preventing reduction of the arc extinguishing capacity due to an alteration of the arc extinguishing chamber caused by an impact.
