Abstract

"UNIDADE DE DESARME DE DISJUNTOR EMPREGANDO UM êMBOLO ROTATIVO E DISJUNTOR". Uma unidade de desarme de disjuntor (2) inclui um alojamento (4) e um êmbolo rotativo (32 ) montado articuladamente dentro do alojamento. O êmbolo rotativo tem uma posição ligado e uma posição desarmado. Uma porção (74) do êmbolo rotativo é pivotada para fora do alojamento na posição desarmado. Uma barra de desarme (76) é montada articuladamente dentro do alojamento e inclui uma primeira ling³eta (262) travando o êmbolo rotativo na primeira posição e liberando o êmbolo rotativo da primeira posição. A barra de desarme também inclui uma segunda ling³eta (100) . Um atuador de desarme (170) inclui um solenóide (122) e uma alavanca de desarme rotativa (101) engatando a segunda ling³eta da barra de desarme, para pivotar a barra de desarme e liberar o êmbolo rotativo da posição ligado. Uma mola (82) força a barra de desarme, para que a primeira ling³eta trave o êmbolo rotativo na posição ligado. Um par de molas (64, 66) força o êmbolo rotativo para a posição desarmado.
