Abstract

SIN UN LIMITADOR (3) DE CORRIENTE DE CORTOCIRCUITO APARECEN EN LOS RECTIFICADORES (1,8) DE CORRIENTE UNA CORRIENTE DE CORTOCIRCUITO MUY ALTA EN EL CIRCUITO (2) INTERMEDIO DE TENSION CONTINUA EN LA DESCARGA POBRE DE IMPEDANCIA DEL CORTOCIRCUITO DE UN CONDENSADOR (C1, C2, C3) DE CIRCUITO INTERMEDIO, QUE CONDUCEN A LAS PARTES DE CONSTRUCCION A FUERZAS ALTAS DE SOLICITACION Y EVENTUALMENTE ARCOS ELECTRICOS EN EL RECTIFICADOR (1,8) DE CORRIENTE. PARA EVITAR ESTO, UN LIMITADOR (3) DE CORRIENTE DE CORTOCIRCUITO REVERSIBLE MUESTREA UN CONDUCTOR (5) FRIO, DE CONDUCTIVIDAD BAJA Y REFRIGERADO AL MEMOS DE UN CONDENSADOR (C2, C3) O DE UN BANDO DE CONDENSADOR DEL CIRCUITO (2) INTERMEDIO DE TENSION CONTINUA CONECTADO EN SERIE. EL CONDUCTOR (5) FRIO PUEDE ESTAR DISPUESTO EN EL CIRCUITO (2) INTERMEDIO DE TENSION CONTINUA O EN EL RECTIFICADOR (1,8) DE CORRIENTE. DE FORMA PARALELA AL CONDUCTOR (5) FRIO PUEDE ESTAR CONECTADO UN VARISTOR (6) Y/O UNA RESISTENCIA (7) A MASA Y/O UN DIODO (4) EN LA DIRECCION DE BLOQUEO DE UNA SENDA DE CORTOCIRCUITO. EL CONDUCTOR (5) EN FRIO Y EL VARISTOR (6) O EL CONDUCTOR (5) EN FRIO Y LA RESISTENCIA (7) A MASA PUEDEN SER REUNIFICADOS PARA LA FORMACION DE UN COMPONENTE.
