Title:
TEMPERATURE COMPENSATION DEVICE FOR RIGID OVERHEAD CATENARY
Document Type and Number:
WIPO Patent Application WO/2017/032316
Kind Code:
A1
Abstract:
Provided is a temperature compensation device for a rigid overhead catenary, wherein one end of a left slide guide rail (2) and of a right slide guide rail (3) are respectively fixedly connected to busbars (1) at two ends. Inner sides of the two slide guide rails are both formed with a slide channel (13) and a slide rail (14) throughout the full length. The two slide guide rails are connected together and can slide freely relative to each other by means of inserting the slide rails(14) into the opposite slide channels (13). The lower ends of outer sides of the two slide guide rails are each formed with a contact wire slot (15) throughout the full length, and the contact wire slots (15) correspond to contact wire slots of the lower ends of the busbars (1) connected thereto. A current conduction rod (7) is mounted on a top face of each of the two slide guide rails via a current conduction support (5) and a parallel current conduction base (6), and the middle section of the current conduction rod (7) extends into the opposite parallel current conduction base (6) and can slide freely along with the two slide guide rails. The device is mounted in the rigid overhead catenary system and compensates for heat expansion and cold contraction of the system due to temperature changes, thereby realizing good electric continuity and smooth transition between anchor segments, ensuring stable operation of the locomotive and enhancing safety and reliability of locomotive operation.
