Abstract

SE PRESENTA UN MECANISMO DE RELE DE SOBRECARGA DE ESTADO SOLIDO DISEÑADO PARA MINIMIZAR LAS FUERZAS REQUERIDAS PARA ABRIR UN CONTACTO ELECTRICO ASOCIADO CON EL MISMO EN EL CASO DE UNA SOBRECARGA DE CORRIENTE EN UN CIRCUITO PROTEGIDO, Y DISEÑADO ADEMAS PARA AGUANTAR EL MAGNETISMO RESIDUAL EN UN SOLENOIDE QUE INICIA LA ABERTURA DEL CONTACTO. EL CONTACTO INCLUYE UN PAR DE CONTACTOS ESTACIONARIOS SOPORTADOS POR UNA BASE Y UN PAR DE CONTACTOS MOVILES SOPORTADOS POR UN SOPORTE DE CONTACTOS. UN PESTILLO DEFINE UNA MUESCA QUE ESTA NORMALMENTE ENGANCHADA CON UNA PALANCA. CUANDO ESTA ASI ENGANCHADA, EL SOPORTE DE LOS CONTACTOS ESTA POSICIONADO DE MANERA QUE LOS CONTACTOS MOVILES ESTEN EN CONTACTO CON LOS CONTACTOS ESTACIONARIOS. CUANDO LA PALANCA SE DESENGANCHA DEL PESTILLO, EL SOPORTE DE LOS CONTACTOS SE MUEVE Y SE ROMPE EL CONTACTO ENTRE LOS CONTACTOS MOVILES Y LOS CONTACTOS ESTACIONARIOS. EL PESTILLO ESTA PROVISTO DE UN CONTRAPESO PARA AYUDAR A MINIMIZAR LA FUERZA REQUERIDA PARA HACER VOLVER EL PESTILLO A SU POSICION ORIGINAL DESPUES DE QUE SE HAYA DISPARADO EL MECANISMO. UN BRAZO DEL PESTILLO SE EXTIENDE DESDE EL PESTILLO AL INTERIOR DEL CAMINO DE LA PALANCA DE MANERA QUE A MEDIDA QUE LA PALANCA SE MUEVE HASTA SU POSICION EXTENDIDA EN UN CAMINO ARQUEADO, LA PALANCA IMPARTA UN MOVIMIENTO SOBRE EL PESTILLO PARA HACERLO VOLVER A SU POSICION INICIAL, SI ESO NO HUBIERA OCURRIDO YA. UN PAR DE CONTACTOS ESTACIONARIOS AUXILIARES ESTA SOPORTADO POR UN ALOJAMIENTO DE CONTACTOS ESTACIONARIOS AUXILIAR Y PUEDE INSTALARSE SELECTIVAMENTE EN UNA POSICION TANTO NORMALMENTE CERRADA COMO NORMALMENTE ABIERTA.
