Abstract

"APARELHO PARA DETECTAR FALHA DE BOBINA EM UM SOLENóIDE DE ATUAçãO DE UMA CHAVE DE FORçA ELéTRICA". A continuidade da bobina (11) do solenóide de atuação (9) de uma chave de força elétrica (1) é detectada através da utilização de um dispositivo sinalizador (45), tal como um diodo emissor de luz (LED) que monitora a energização de um suprimento de energia CC (25) alimentado a partir do lado da fonte da bobina (11). Um circuito (51) energizado a partir do outro lado da bobina (11) gera uma voltagem CC V2 que é aplicada ao eletrodo de portão de um comutador eletrónico (47) desviando o LED (45). A voltagem V2 é maior que a voltagem de suprimento para polarizar o comutador eletrónico (47) para desligar tal que o LED (45) esteja iluminado quando houver continuidade através da bobina (11) . Se a bobina (11) falhar, V2 será zero e o comutador eletrónico (47) é ligado para desenergizar o LED (45) para sinalizar a falha da bobina (11).
