Method for monitoring railway track contact wires involves measuring position of balance weight on support mast and recording deviation of balance weight from neutral position at known temperature

摘要

Monitoring of track contact wires (1) fastened on support masts (5) by tensioning devices and balance weight (12) involves determining the temperature and/or wear of the lines. The position of the balance weight on the support mast is measured, the deviation of the balance weight from a neutral position at a known temperature is recorded, and from the position deviation and length expansion coefficient of the contact wire material an additional parameter of the contact wire is derived. An independent claim is included for a device to carry out the above method.
