Abstract

alavanca de reajuste de desengate de pistão trata-se de um dispositivo para transferir o movimento de uma alavanca manual para uma alavanca de reajuste de um mecanismo de desengate por pressão em um disjuntor de caixa moldada. o mecanismo de desengate por pressão é ativado quando gases quentes são liberados durante um evento de arco e o aumento de pressão resultante força o pistão no mecanismo a expandir-se e ativar assim o disjuntor. em alguns eventos de interrrupção, gases quentes e, ocasionalmente, fragmentos de metal em estado de fusão, são responsáveis pela danificação da superfície de plástico do pistão do mecanismo de desengate por pressão e impedem que o mecanismo volte à sua posição de pré-interrupção mesmo quando ele é inclinado até a posição de pré-interrupção com uma mola. uma configuração aqui revelada proporciona a articulação do movimento da alavanca manual usada para reajustar o disjuntor com a alavanca de reajuste conectada ao mecanismo de desengate por pressão de modo a forçar o mecanismo de desengate por pressão a voltar à sua posição de pré-interrupção.
