Abstract

EL INTERRUPTOR DI TIENE UN TRANSFORMADOR (2) DE CORRIENTE TOTALIZADA CUYA INDUCTIVIDAD FORMA, JUNTO CON UNA CAPACIDAD DE MEDICION (8) UN CIRCUITO DE OSCILACIONES CUYA POTENCIA ABSORBIDA SE MODIFICA CON LA AMPLITUD DE UNA CORRIENTE DE ERROR IF Y QUE TIENE ASIGNADO UN RECTIFICADOR DE DOBLE VIA (21) CON DIODOS (22 A 25) Y UN COMPARADO (34). SEGUN EL INVENTO, PARA LA COMPENSACION DE TEMPERATURAS DE LOS DIODOS (22 A 25), SE DA AL COMPARADOR (34) UNA CORRIENTE DE COMPENSACION IK, INDEPENDIENTE DE LA CORRIENTE DE ERROR IF. ESTA CORRIENTE DE COMPENSACION IK PUEDE DERIVARSE DE UN DIVISOR DE TENSION (40) QUE TIENE UNA RESISTENCIA INDEPENDIENTE DE LA TEMPERATURA. EN ESTE TIPO, LA SEÑAL DE SALIDA DEL INTERRUPTOR DE PROTECCION DE CORRIENTE DIFERENCIAL ES INDEPENDIENTE DE GRANDES OSCILACIONES DE LA TEMPERATURA DE AMBIENTE.
