Abstract

DISPOSITIVO DE DETECCION DE LAS TRANSICIONES AL ESTADO NORMAL EN UN BOBINADO SUPERCONDUCTOR, ESPECIALMENTE DE GENERADOR ELECTRICO, Y DE PROTECCION DE TAL BOBINADO. DISPOSITIVO DE DETECCION DE LAS TRANSICIONES AL ESTADO NORMAL EN UN BOBINADO SUPERCONDUCTOR A FRECUENCIA INDUSTRIAL, ESPECIALMENTE PARA EL INDUCIDO DE UN GENERADOR ELECTRICO (1). COMPRENDE UN GENERADOR AUXILIAR (4) DE UNA CORRIENTE DE PEQUEÑA INTENSIDAD DE FRECUENCIA NOTABLEMENTE MAS ELEVADA QUE LA FRECUENCIA INDUSTRIAL, MONOFASICA O POLIFASICA SEGUN QUE LA CORRIENTE PRINCIPAL QUE RECORRE EL BOBINADO SEA MONOFASICA O POLIFASICA, MONTADA EN PARALELO CON EL BOBINADO SUPERCONDUCTOR, Y LOS ELEMENTOS (5, 6) PARA DETECTAR LA VARIACION DEL DESFASE ENTRE INTENSIDAD Y TENSION DE LA CORRIENTE AUXILIAR CUANDO LOS CONDUCTORES DE ESTE BOBINADO PASAN AL ESTADO NORMAL.
