Abstract

UN INTERRUPTOR ELECTRICO QUE CONSTA DE DOS CONTACTOS FIJOS (1, 2) Y UN CONTACTO MOVIL (3), QUE JUNTOS FORMAN EL SISTEMA DE CONTACTO PRINCIPAL, QUE SE ENCUENTRA EN UNA CAVIDAD CON AISLAMIENTO DE ACEITE (13) ENCERRADA EN UN RECEPTACULO (10). EN SU DIRECCION DE MOVIMIENTO, EL CONTACTO MOVIL TIENE UNA EXTENSION A MODO DE EJE (14). EL EJE TIENE UN PISTON HIDRAULICO CON EL QUE SE ACTIVA EL CONTACTO MOVIL. EL PISTON HIDRAULICO SE ENCUENTRA RODEADO DE UNA CAVIDAD EN QUE HAY FORMADA UNA CAVIDAD DE PISTON (15, 16) A CADA LADO DEL PISTON HIDRAULICO. LAS CAVIDADES DE PISTON SE RELLENAN CON ACEITE. EL MOVIMIENTO DEL EJE QUEDA DETERMINADO POR UNA VALVULA DIRECCIONAL CONTROLADA ELECTRICAMENTE (21). LA VALVULA DIRECCIONAL RECIBE SEÑALES QUE INDICAN SI EL INTERRUPTOR ELECTRICO SE ENCUENTRA ABIERTO O CERRADO. ANTE UNA SEÑAL DADA, LA VALVULA DIRECCIONAL DISTRIBUYE UNA PRESION ELEVADA A LA CAVIDAD DE PISTON QUE SE VA A ALARGAR. EL INTERRUPTOR ELECTRICO PUEDE TENER UN MECANISMO DE CONTACTO AUXILIAR QUE SE PUEDECOLOCAR BIEN EN LOS CONTACTOS FIJOS Y/O EN EL CONTACTO MOVIL. EL INTERRUPTOR ELECTRICO PUEDE TENER UN MECANISMO DE BIESTABILIDAD QUE CONSTA DE PISTONES CUNEIFORMES (45, 46), POLARIZADOS MEDIANTE RESORTES (47, 49), Y QUE, EN CASO DE UNA CAIDA DE PRESION, DICHOS PISTONES CUNEIFORMES BLOQUEAN EL CONTACTO MOVIL EN LA POSICION EXISTENTE A TRAVES DEL EJE.
