Abstract

"MONITOR DETECTOR DE FALHAS EM INSTALAçãO DE TRANSFORMADOR DE LUMINOSOS A GáS NEON". Composto de um circuito eletrónico instalado dentro do compartimento do transformador para supervisionar e desligar o transformador em caso de falhas. Baseado em um microcontrolador digital programado que é conectado no transformador, e que fornece uma corrente de excitação ao "TRIAC" que liga/deslIga a primária do transformador na tensão AC da rede elétrica como também fornece uma corrente para acender um LED de luz vermelha quando ocorre uma falha e um LED de luz verde que indica se existe alimentação da rede. Quando o luminoso opera normalmente, o TRIAC está acionado e o transformador permanece ligado e o LED de luz vermelha permanece apagado, enquanto o LED de luz verde permanece aceso. Quando ocorrer qualquer falha na instalação, instantaneamente o monitor detecta a falha e o transformador é imediatamente desligado e seis segundos depois ele é religado automaticamente. Se a causa da falha desaparecer o transformador continuará operando normalmente. Entretanto, se a falha persistir o transformador será desligado pela segunda vez e seis segundos após o transformador é religado novamente. Se ainda assim a falha persistir o transformador será desligado pela terceira vez em caráter definitivo, ocasião em que um LED de aviso começará a piscar informando inclusive o tipo de falha ocorrida até que um técnico de manutenção compareça no local e efetue o reparo necessário.
