Abstract

DISPOSITIVO DE PROTECCION PARA UN MOTOR ELECTRICO. EL DISPOSITIVO COMPRENDE UN CONTENEDOR (2) AISLANTE, A CUYA PARED DEL FONDO LLEVA CONECTADOS TRES TERMINALES ELECTRICOS (10 A 12) ACCESIBLES DESDE EL EXTERIOR. EN EL CONTENEDOR (2) UN ORGANO BIMETALICO (20) ESTA ASOCIADO CON DOS DE DICHOS TERMINALES (10, 11) Y SIRVBE PARA CONECTAR ELECTRICAMENTE, EN SU ESTADO INDEFORMADO, A FIN DE PERMITIR LA ALIMENTACION DE CORRIENTE A UN MOTOR ELECTRICO. UNA RESISTENCIA (40) UNIDA ENTRE UNO DE DICHOS DOS TERMINALES (10) Y UN TERCER TERMINAL (12), ES RECORRIDA POR LA CORRIENTE DE ALIMENTACION DEL MOTOR, Y COLABORA JUNTO CON EL AUTOCALENTAMIENTO DEL ORGANO BIMETALICO, PARA DETERMINAR LA DEFORMACION DE DICHO ORGANO (20) A FIN DE INTERRUMPIR LA ALIMENTACION DE CORRIENTE AL MOTOR CUANDO DICHA CORRIENTE SUPERA UN VALOR PREESTABLECIO.
