Abstract

RELE DE SOBREINTENSIDAD TEMPORIZADOS DE TIPO ELECTRONICO. CONSISTE EN UN DISPOSITIVO ELECTRONICO QUE PROPORCIONA UNA SEÑAL DE SALIDA EN RESPUESTA A UNA SEÑAL ALTERNA DE ENTRADA QUE PRESENTA UNA PRIMERA FRECUENCIA SUPERIOR A UN NIVEL MINIMO DE EXCITACION PREAJUSTADO, VARIANDO EL TIEMPO DE APARICION DE LA SEÑAL DE SALIDA CON RELACION AL TIEMPO EN QUE LA SEÑAL DE ENTRADA REBASA EL NIVEL MINIMO DE CAPTACION EN RELACION INVERSA RESPECTO A UN VALOR MEDIO DE LA SEÑAL DE ENTRADA. CONSTA DE UN RECTIFICADOR TRIFASICO (32), REALIZANDOSE UN MUESTREO (40) QUE SE LLEVAN AL CONVERTIDOR ANALOGICO DIGITAL (38) QUE CONVIERTE LAS MUESTRAS EN NUMEROS BINARIOS QUE PASAN A UN DISPOSITIVO CONTADOR (60) QUE EXCITA UNA SEÑAL DE SALIDA EN CASO DE QUE REBASE UN NUMERO LIMITE. LINEAS DE DISTRIBUCION DE ENERGIA ELECTRICA.
