<p>Device (1) for regulating the pressure force of a pantograph (30) of a railway train (10) on a catenary wire (2), the said pantograph (30) comprising, at its upper end, a bow (3) in mechanical and electrical contact with the catenary wire (2), and being connected mechanically to actuating means (7, 34) applying to it a nominal force at predetermined points and in a predetermined direction. This device comprises:… - means (31) for measuring the contact force between the bow (3) of the pantograph (30) and the catenary wire (2), and for supplying data relating to the measured force,… - means (5, 4a) for transmitting the measurement data from the said measuring means (31, 40) to an appropriate zone of the railway train (10),… - means (60, 20) for processing the transmitted data and reference signals, and for supplying logic control signals, and… - means (50) for controlling the said actuating means (6, 7) from the said logic control signals, when the measured contact force exceeds a predetermined maximum force threshold (Smax) or in response to predetermined external-control signals. …<??>Use for equipping pantographs of very high-speed railway trains following lines with conventional overhead wires or variable height. …<IMAGE>… </p> |
