Abstract

DISPOSITIVO ELECTRONICO DE PROTECCION TERMICA PARA MOTORES ELECTRICOS. LA TENSION IMAGEN DE LA CORRIENTE, RECTIFICADA (402, 502, 602) Y FILTRADA (704, 705) SE APLICA A UN COMPARADOR (8). ESTE RECIBE, A SU VEZ,UNA INDICACION DEL ESTADO EN MARCHA DEL MOTOR Y PROVOCA LA DESCARGA PROGRESIVA DE UN CONDENSADOR (802). LA TENSION EN BORNAS DE ESTE CONDENSADOR (802) ES APLICADA A OTRO COMPRADOR (10), QUE PROPORCIONA ASI UNA SEÑAL DE ACCIONAMIENTO DE INTERRUPCION.
