Abstract

DSIPOSITIVOS DE PROTECCION DE CIRCUITOS ELECTRICOS (1) QUE CONTIENEN ELEMENTOS PTC (2) COMPUESTOS DE POLIMEROS CONDUCTIVOS (3) QUE MUESTRAN COMPORTAMIENTO PTC Y SON USADOS PARA PROTEGER UNA CARGA EN UN CIRCUITO ELECTRICO, EN LOS QUE LOS POLIMEROS CONDUCTIVOS PTC ESTAN BASADOS EN POLIMEROS DE CRISTAL LIQUIDO (3.1) ALTAMENTE ORDENADOS Y ALTAMENTE CRISTALINOS Y RELLENO CONDUCTOR DE PARTICULAS (3.2) ESPARCIDAS DENTRO, QUE ESTAN UNIDAS POR RADIACION. ESTOS DISPOSITIVOS DE PROTECCION DE CIRCUITOS (1) OPERAN COMO LIMITADORES DE CORRIENTE RESETEABLES AUTOMATICAMENTE Y SON PARTICULARMENTE UTILES PARA PROTEGER MOTORES, SELENOIDES, LINEAS DE TELEFONO Y BATERIAS, Y PARA AUMENTAR LA CAPACIDA DE INTERRUPCION DEL CIRCUITO CUANDO SE USA EN UNION CON ITNERRUPTORES Y CONTACTOS. LOS POLIMEROS DE CRISTAL LIQUIDO (3.1) INCLUYEB POLIESTERES; EJEMPLO, POLIETILENO (P-FENILENO TREFTALEITA) Y POLIETILENO (P-HIDROXIBENZOATO); COPOLIESTERES AROMATICOS, EJEMPLO; POLIETILENO (DECA-METILNOTRIFTALEITOL DI-PHIDROXIBENZOATO) Y POLIETILENO (ETILENO TRIFTALEITA-COOXIBENZOATO); AMIDAS COPOLIESTERES AROMATICAS, EJEMPLO; POLIETILENO (2,6,-HIDROXI-NAFTOLFENOXIAMINOTREFTALEITA);POLIAMIDAS AROMATICAS,POR EJEMPLO,POLIETILENO (P-FENILO-TREFTALEIAMIDA), KEVLAR, POLIETILENO (P-BENZOAMIDA),POLIETILENO (2-CLORO-1,4-FENILO TREFTALEIAMIDA), POLIETILENO (P-P''-BIFENILAMIDA), Y POLIETILENO (2,6-NAFTOLAMIDA); POLIAZOMETILOS AROMATICOS, POR EJEMPLO POLIETILENO (NITRO-2-METIL-1, 4-FENILENONITRILOETILIDINO-1, 4FENILOETILIDINO), POLIETILENO (NITRILO-2-METIL-1, 4FENILINONITRILO-METILIDINA-1, 4-FENILOETILIDINO), Y POLIETILENO (NITRILO-2-CLORO-1, 4-FENILONITRILOMETILIDINA-1,4FENILOMETILIDINA); Y COMPOSICIONES DE LAS MISMAS. LOS RELLENOS CONDUCTIVOS DE PARTICULSA (3.2) INCLUYEB MANCHAS DE CARBON, FIBRAS DE CARBON, GRAFITO Y TROZOS DE METAL.
