Title:
SYSTEM FOR OPERATING AN ELECTRIC TRACTIVE UNIT
Document Type and Number:
WIPO Patent Application WO/2013/023946
Kind Code:
A3
Abstract:
System for operating an electric tractive unit. The invention relates to a system (1) for operating an electric tractive unit (10), having a contact line system (20) which is arranged along a route (2) of the tractive unit (10). In this context, a current collector (11) of the tractive unit (10) for transmitting energy can be placed in sliding contact with a contact line (23) of the contact line system (20). In addition, the contact line (23) is divided by a section insulator (24), along which the current collector (11) can travel with sliding contact, into contact line sections (23a, 23b) which are supplied with electricity separately from one another. According to the invention, a detection device (30) is designed to detect when travel over the section insulator (24) by tractive unit (10) is imminent. Said detection device (30) interacts with a drive controller (13) for an electric drive (12) of the tractive unit (10) in such a way that transmission of energy via the current collector (11) while the section insulator (24) is being travelled over is automatically reduced or switched off. As a result, the wear on section insulators (24) can be reduced.
