Overhead contact line and/or chain work and/or electricity consumer`s deflection and/or force measuring device for electrically operated railway track, has fiber-optic cable transmitting optical output signals of sensor to computer

摘要

The device has an acceleration sensor (8) measuring position and/or movement and/or acceleration and/or jerk of overhead contact lines and/or chain work and/or electricity consumers and/or measuring a contact force between the line and consumer. The sensor is attached at the overhead contact lines and/or supports of the lines and/or the electricity consumers at high voltage potential. A fiber-optic cable (7) transmits optical output signals of the sensor to a computer. An opto-coupler converts one of the optical output signals into an electrical signal at ground potential.
