Abstract

DE FORMA ESPECIAL LOS CONTACTOS DE PROTECCION, CON LOS CUALES LAS PIEZAS DE CONTACTO SUFREN UNA MERMA EN LOS PROCESOS DE CONEXION, SE VALORAN SEGUN LOS CRITERIOS DE SUSTITUCION CON RESPECTO A ESTA MERMA. DE ACUERDO CON LA INVENCION SE ELIGE COMO CRITERIO DE SUSTITUCION DE LA PRESION DE LA ROTURA DE CONTACTO CONOCIDA EN LA PIEZA DE CONEXION PARA LA DETERMINACION DE LA MERMA DE CONTACTO EN LA MODIFICACION DE LA PRESION DURANTE EL PROCESO DE DESCONEXION Y CON ELLO SE CALCULA LA DURACION DE VIDA RESIDUAL. EN UNA DISPOSICION PERTENECIENTE LA UNIDAD DE PROCESADO DISPONE DE UN CONTROLADOR (40), UNA MEMORIA (41) PERTENECIENTE Y UN DISPOSITIVO PARA LA INDICACION DEL VALOR DETERMINADO. EVENTUALMENTE EL APARATO DE CONEXION PUEDE TENER LOS MEDIOS DE INDICACION CORRESPONDIENTES PROPIOS.IN A SPECIAL WAY THE PROTECTION CONTACTS, WITH WHICH THE CONTACT PIECES SUFFER A DECREASE IN THE CONNECTION PROCESSES, ARE VALUED ACCORDING TO THE SUBSTITUTION CRITERIA REGARDING THIS DECREASE. IN ACCORDANCE WITH THE INVENTION, THE CRITERIA FOR SUBSTITUTING THE PRESSURE OF THE BREAKAGE OF CONTACT KNOWN IN THE CONNECTION PIECE FOR THE DETERMINATION OF THE PRESSURE DAMAGE DURING THE DISCONNECTION PROCESS IS SELECTED AND WITH IT THE CALCULATION OF THE RESIDUAL LIFE DURATION. IN A BELONGING PROVISION THE PROCESSING UNIT HAS A CONTROLLER (40), A BELONGING MEMORY (41) AND A DEVICE FOR THE INDICATION OF THE DETERMINED VALUE. EVENTUALLY THE CONNECTION DEVICE MAY HAVE THE PROPER CORRESPONDING MEANS OF INDICATION.
