Abstract

Patente de Invenção: <B>"INTERRUPTOR ELéTRICO DE PROTEçãO PARA APARELHO COM FUNçãO DE SOBRECORRENTE E SUBTENSãO E SENSOR DE SOBRECORRENTE PARA ELE"<D>. O interruptor elétrico de proteção para aparelho abrange um contato de comutação mecânico (2) para um condutor de corrente (S1-S3), um mecanismo de engate travável (6) para o contato de comutação (2), um sensor de sobrecorrente (3), e um relé de sobretensão eletromecânico (7), cuja tensão de exitação é derivada da tensão de condutor de corrente e que trava no estado excitado da chave de conexão (6). O sensor de sobrecorrente (3) produz, quando de sobrecorrente, a separação do relé de subtensão (7) de sua tensão de excitação, a qual deixa de existir também no caso de subtensão. A solução do travamento da chave de conexão (6) é, com isto, produzida tanto no caso de sobrecorrente como também no caso de subtensão pelo mesmo componente, nomeadamente o relé de subtensão (7). O sensor de sobrecorrente 3 é formado, de preferência, por meio da combinação de um conversor de corrente com um circuito eletrónico, o qual, por seu lado, de preferência, é executado como circuito integrado. Um conversor de corrente especialmente simples para a detecção da corrente que flui do condutor de corrente (S1-S3) resulta por meio de um par de enlaces indutivos dos dois lados de um segmento do condutor de corrente em uma placa condutora, sendo que para a configuração de um núcleo de ferro para o conversor de corrente pode estar previsto um par de metades de núcleo de ferro (K11 - K32) dispostos contrapostos dos dois lados da placa condutora.
