THERMAL RELAY FOR OVERLOAD PROTECTION OF OVERHEAD LINES

THERMISCHES UEBERLASTSCHUTZRELAIS FUER FAHREITUNGEN

Overhead line system of German Federal Railways and its thermal behavior are described. The operating principle of the thermal overload relay is outlined. A tripping signal is initiated when the contact wire has reached a certain final temperature. For this purpose, the ambient temperature is measured at the relay location and the temperature rise is simulated on the basis of the respective current loading.
