Abstract

"DISPOSITIVO PARA A PROTEçãO DE UM MANCAL DE UMA MáQUINA ELéTRICA CONTRA UMA PASSAGEM DE CORRENTE DESTRUTIVA". A invenção refere-se a um dispositivo para a proteção de um mancal (7) de uma máquina elétrica contra uma passagem de corrente destrutiva, sendo que a máquina elétrica apresenta um estator (11) e um rotor (5) que é montado girando em relação ao estator (11) por meio de pelo menos um mancal (7), em que está previsto um circuito de compensação para a geração de uma corrente de compensação destinada à compensação de uma corrente parasita através do mancal (7), que ocorre por ocasião da operação da máquina elétrica, e um elemento de acoplamento (23) para o acoplamento direto ou indireto da corrente de compensação no mancal (7).
