Abstract

The invention provides a rigid-flexible transition busbar, which belongs to the technical field of electrified railway and urban rail transit overhead catenary. It solves the problems of transitional hardness and high cost in the existing rigid-flexible transition busbar. The rigid-flexible transitional bus bar includes a bus bar body. The two ends of the bus bar body are respectively a rigid connection end and a flexible connection end. The lower part of the bus bar body has a clamping jaw. The rigid-flexible transition part whose body rigidity gradually decreases, the upper surface of the rigid-flexible transition part is a continuous transition slope; the bus bar body is distributed along the length direction with several connecting through holes passing through the bus bar body, and locks are respectively installed in the connecting through holes. Each locking bolt is covered with a positioning sleeve, and the two end surfaces of the positioning sleeve respectively abut against the inner surface of the main body of the bus bar. The rigid-flexible transitional busbar adopts a continuous transition slope for transition, eliminating hard points in the rigid-flexible transitional busbar.

Description

Technical field

[0001] The invention belongs to the technical field of electrified railways and urban rail transit overhead contact nets, and relates to a busbar, in particular a rigid-flex transition busbar. Background technique

[0002] The overhead catenary of electrified railway and urban rail transit generally adopts rigid suspension in tunnels, and adopts flexible suspension on the ground or viaducts. Rigid-flexible transition refers to the transition between the two catenary modes of rigid suspension and flexible suspension.

[0003] Existing rigid-flexible transition devices, for example, Chinese patent [Application No. 200620078307.4; Authorized Announcement No. CN2900226Y] discloses a busbar rigid-flexible transition device. The top surface of the right part of the busbar body is recessed at regular intervals. The depth of the groove and the groove gradually increase in a single direction. The side of the busbar body is provided with through holes at equal intervals, and...
