Abstract

APARATO PROTECTOR CONTRA SOBRETENSIONES ELECTRICAS. COMPRENDE UNA ETAPA DE DIODOS ZENER, VARISTORES, DESCARGADORES DE GAS U OTROS COMPONENTES CUYA IMPEDANCIA SE REDUZCA A PARTIR DE UN CIERTO VOLTAJE, MONTADOS EN SERIE Y/O EN DERIVACION, CON UNO DE SUS TERMINALES APLICADO A UN CONDUCTOR DE SALIDA DEL INTERRUPTOR DIFERENCIAL ASOCIADO A LA ALIMENTACION DEL RECEPTOR, MIENTRAS QUE EL OTRO TERMINAL DE LA PROPIA ETAPA SE HALLA APLICADO AL OTRO CONDUCTOR ANTES DE LA ENTRADA DEL MISMO EN EL INTERRUPTOR DIFERENCIAL, DERIVANDOSE UNA CORRIENTE DE DESCARGA HACIA DICHO OTRO CONDUCTOR. APLICABLE A LA PROTECCION DE RECEPTORES ELECTRICOS QUE REQUIEREN UNA ALIMENTACION UNIFORME Y SON SENSIBLES A PICOS DE TENSION.
