Abstract

APARATO PARA LA DETECCION DE DEFECTOS HOMOPOLARES Y/O DE CORTOCIRCUITO EN LINEAS AEREAS DE MEDIA TENSION. COMPRENDE MEDIOS DE CAPTACION (1) DEL CAMPO MAGNETICO PRODUCIDA POR LAS LINEAS (A, B, C) CUYOS DEFECTOS SE QUIEREN DETECTAR, MEDIOS DE AMPLIFICACION (3, 11) DE LA SEÑAL PROPORCIONADA POR LOS MEDIOS DE CAPTACION, MEDIOS DE COMPARACION (4) DE LA SEÑAL AMPLIFICADA CON UNA SEÑAL DE REFERENCIA Y MEDIOS INDICADORES (5) DE LA EXISTENCIA DE DEFECTO EN LAS LINEAS (A, B, C), Y SE CARACTERIZA LOS MEDIOS DE CAPTACION (1) COMPRENDEN DOS BOBINAS (7, 8) DISPUESTAS EN POSICION SENSIBLEMENTE HORIZONTAL, Y SEPARADAS ENTRE SI UNA DISTANCIA SUPERIOR A 20 CM. PREFERENTEMENTE, COMPRENDE UN DISPOSITIVO (10) PARA EL AJUSTE DE FASE, UN DISPOSITIVO (9) PARA EL AJUSTE DE MODULO Y UN DISPOSITIVO (11) PARA EL AJUSTE DE GANANCIA PARA LA DETECCION DE DEFECTOS HOMOPOLARES, Y UN DISPOSITIVO (3) PARA EL AJUSTE DE GANANCIA PARA LA DETECCION DE DEFECTOS DE CORTOCIRCUITO, DISPONIENDO DE UNA PUERTA AND O NAND (12) Y DE UN COMPARADOR COMUN (4) CONECTADO A LOS MEDIOS INDICADORES (5). PERMITE LA DETECCION DE AMBOS DEFECTOS CON UN COSTE REDUCIDO.
