Abstract
EL DISPOSITIVO EVITA LOS INCONVENIENTES DE UNA LIMITACION DE CORRIENTE A TRAVES DEL CIRCUITO DE CARGA (RL) AL QUE ESTA ENLAZADA LA FUENTE DE TENSION (ST), PARA PERMITIR LAS DEMANDAS DE CORRIENTE TRANSITORIA, Y REMEDIR CON UNA DISIPACION DE ENERGIA AL PRODUCIRSE EL CORTACIRCUITO. EL DISPOSITIVO CONSTA DE UN CIRCUITO DETECTOR-MEDIDOR (DM) DE TENSION DE CARGA VL SUPERIOR A UNOS UMBRALES VL1 Y VL2 < VL1, UNA TERMISTANCIA (TH) CON COEFICIENTE DE TEMPERATURA POSITIVO DE TENSION DE BASCULAMIENTO VL2< VTHB (MENOR O IGUAL) VL1, UN INTERRUPTOR ELECTRONICO (IE) EN SERIE CON LA TERMISTANCIA (TH) Y CONTROLADO POR ELCIRCUITO DETECTOR-MEDIDOR (DM), Y UNA RESISTENCIA DE DERIVACION (RD). EL INTERRUPTOR BASCULA DEL ESTADO NORMAL CERRADO AL ESTADO ABIERTO CUANDO VL > VL1 EN RESPUESTA A UN CORTOCIRCUITO, ENLAZANDOSE ENTONCES LA FUENTE (ST) A LA RESISTENCIA DE DERIVACION ELEVADA (RD), Y DEL ESTADO ABIERTO AL ESTADO CERRADO CUANDO VL > VL2.
