Abstract

UN DISPOSITIVO OPERADO DE FORMA MANUAL O AUTOMATICA PARA DESCONECTAR RAPIDAMENTE LA LINEA DE ALIMENTACION ENTRE UNA FUENTE DE CORRIENTE Y EL CIRCUITO DE USUARIO EN CASO DE URGENCIA, P. EJ., EN APLICACIONES AUTOMOTRICES, PARA ELIMINAR EL RIESGO DE INCENDIO DEBIDO A COMPRESION ACCIDENTAL DE LOS CABLES POSITIVOS EN EL CASO DE UN CHOQUE; EL DISPOSITIVO PRESENTA UN PRIMER Y SEGUNDO ELEMENTOS DE CONTACTO CONECTADOS EN SERIE ENTRE DOS TERMINALES DE LA LINEA Y MOVILES EN RELACION ENTRE SI EN OPOSICION A ELEMENTOS ELASTICOS, Y ELEMENTOS DE CONTROL PARA MOVER SELECTIVAMENTE LOS CONTACTOS A UNA PRIMERA POSICION DE TRABAJO EN DONDE SE PONEN EN CONTACTO ENTRE SI PARA HACER UN CORTOCIRCUITO DE LA LINEA, Y UNA SEGUNDA POSICION DE SEGURIDAD EN DONDE SE SEPARAN PARA DESCONECTAR LA LINEA; LOS ELEMENTOS DE CONTACTOS ESTAN DEFINIDOS POR ESCOBILLAS DE CARBON REALIZADAS DE UNA MEZCLA SINTERIZADA DE POLVO DE CARBON Y PARTICULAS DE COBRE, Y DEL MISMO TIPO UTILIZADO EN MOTORES DE CONMUTADOR COLECTOR.A DEVICE OPERATED MANUALLY OR AUTOMATICALLY TO QUICKLY DISCONNECT THE POWER SUPPLY BETWEEN A CURRENT SOURCE AND THE USER CIRCUIT IN CASE OF URGENCY, e.g., in AUTOMOTIVE APPLICATIONS, TO ELIMINATE THE RISK OF COMPRESSION DUE TO DAMAGE POSITIVE CABLES IN THE CASE OF A SHOCK; THE DEVICE PRESENTS A FIRST AND SECOND CONTACT ELEMENTS CONNECTED IN SERIES BETWEEN TWO TERMINALS OF THE LINE AND MOBILE IN RELATION BETWEEN IN OPPOSITION TO ELASTIC ELEMENTS, AND CONTROL ELEMENTS TO SELECTLY MOVE CONTACTS TO A FIRST WORKING POSITION WHERE IN CONTACT BETWEEN TO MAKE A SHORT CIRCUIT OF THE LINE, AND A SECOND SECURITY POSITION WHERE THEY SEPARATE TO DISCONNECT THE LINE; THE CONTACT ELEMENTS ARE DEFINED BY CARBON BRUSHES MADE OF A SINTERED MIXTURE OF COAL POWDER AND COPPER PARTICLES, AND OF THE SAME TYPE USED IN COLLECTOR SWITCH MOTORS.
