Abstract

EL DISPOSITIVO (25) PARA VERIFICAR Y SEÑALAR LA AUSENCIA DE AISLAMIENTO ELECTRICO ENTRE LA UNIDAD DE TRACCION Y LA CARROCERIA EN VEHICULOS ELECTRICOS COMPRENDE UN GENERADOR (47) DE VOLTAJE DE CORRIENTE ALTERNA PARA APLICARSE A LA TRACCION DEL VEHICULO Y ALIMENTAR EL CIRCUITO MEDIANTE SISTEMAS DE DESACOPLADO DEL CONDENSADOR (38), PARA ELIMINAR LOS EFECTOS DEL VOLTAJE DE CORRIENTE ALTERNA DE LA BATERIA. UNA RESISTENCIA EN DERIVACION (37) SE ACOPLA EN SERIE CON EL GENERADOR DE VOLTAJE, LA TENSION DE CUYA RESISTENCIA COMO INDICADOR DE LA CORRIENTE ALTERNA ORIGINADA POR EL VOLTAJE DE CORRIENTE ALTERNA APLICADO EN PRESENCIA DE DISPERSIONES CON RESPECTO DE LA CARROCERIA QUE CIERRA EL CIRCUITO COMPRENDIENDO EL GENERADOR DE VOLTAJE Y LA RESISTENCIA EN DERIVACION. GRACIAS A LA MEDIDA DE LA CORRIENTE DE DISPERSION PRESENTE EN EL CIRCUITO ES POSIBLE DETECTAR LA PRESENCIA DE DISPERSIONES Y DE CORTOCIRCUITOS CON RESPECTO DE LA CARROCERIA Y GENERAR UNA SEÑAL APROPIADA PARA EL CONDUCTOR.
