Abstract

DETECçãO DE DESEQUILìBRIO DE CIRCUITO APLICáVEL EM AVIõES E INTERRUPTOR DE CIRCUITO E EMPACOTAMENTO DO MESMO. A presente invenção refere-se a uma detecção de desequilíbrio de corrente e interruptor de circuito aplicável em avião que interrompe um circuito elétrico quando um desequilíbrio de corrente é detectado. A detecção de desequilíbrio de corrente e interruptor de circuito inclui um alojamento, fontes de alimentação, um sistema de sensor para detectar um desequilíbrio de corrente no lado de linha do circuito elétrico, um controlador lógico e um controlador de energia que inclui um relé de energia que tem contatos capazes de sobreviverem aos tipos de interrupção de carga e fazer interrupção de carga de condições de falha de terra nos níveis de corrente previstos. Na partida, o dispositivo executa um teste para confirmar que nenhum dos contatos do relé falhou em uma posição fechada, e verificar se um FET de comutação o qual controla a bobina do relé está em curto.
