Description
Technical Field
The invention belongs to the technical field of parts of overhead contact systems of electrified railways, and particularly relates to a counterweight device for contact lines of electrified railways.
Background
The overhead contact system is a special type power transmission line which is erected along the overhead of a railway line and supplies power to an electric locomotive, and mainly comprises a contact line and a carrier cable. The railway line comprises a straight line section and a curve section, and the minimum curve radius of the curve section can reach 300 meters under difficult conditions. The contact net clues are in a broken line shape when arranged in the curve sections and are in a zigzag shape when arranged in the straight sections. The horizontal component force (the horizontal component force is called a curve force when the curve section is a curve force and is called a character force when the straight line section is a curve force) is generated at the strut point due to the change of the direction of the clue, the contact line is generally controlled within the effective working range of the pantograph of the electric locomotive through the locator, and meanwhile, a certain angle is reserved between the locator and the horizontal component force in order to ensure the safety of the pantograph. Because of this angle between the positioner and the horizontal component, as the horizontal tension of the cord increases, the component in the vertical direction will also increase. If the vertical upward component is greater than the gravity component of the thread itself, the contact line will be moved upward and the height of the wire will be increased. Meanwhile, in the design specification of railway electric traction power supply (TB 10009-2016), the maximum height of a contact wire from a rail surface is specifically required.
The vertical upward component force can be effectively reduced by reducing the contact line tension, but the contact line sag can be increased, the technical standard of a circuit is reduced, potential safety hazards are caused, and certain limitation exists.
Therefore, it is necessary to develop a novel device, which can control the increase of the height of the lead wire of the contact wire caused by overlarge curve force, meet the requirements of the high technical standard of the contact network of the electrified railway, has the national general use standard of the railway, and can ensure the stability of the equipment and the running safety of the railway after installation.
