A method for the automatic detection of critical regions of a contact wire of the overhead line of rail-bound vehicles

摘要

The invention relates to a method for the automatic detection of critical regions of a contact wire of the overhead line of rail-bound vehicles, wherein the overhead line under the operating voltage is detected and the measurement is carried out without interruption.It is the object of the invention, the disadvantages of the prior art by a method to be eliminated, which is an uninterrupted, automatic and location-related recording of critical regions of a contact wire ensures.This is achieved according to the invention in that the current collector with optical and / or electromechanical and / or inductive sensors is provided, wherein the sensors at the locations of the grinding surface or the emergency running of the current collector are arranged in the form of a critical and thus are intended to be tested. They are, via electrical or glass fiber lines with one or more computers, hereinafter referred to as the computer unit connected. Because of the placement of the a - and out, or other contact wire, the optical and / or mechanical and / or inductive sensors are excited. At the instant in which one of the sensors is excited, a signal to the computer unit.
