Description

Busbar for rigid suspension contact net

Technical Field

Background

Overhead contact networks are divided into flexible suspension contact networks and rigid suspension contact networks. The flexible suspension contact network is widely applied to domestic and foreign electrified railways and urban rail transit systems, but the flexible suspension contact network is complex in structure and is greatly limited and influenced by tunnel clearance, and at present, more and more urban rail transit projects adopt rigid suspension contact network systems.

The bus bar is a main part of a rigid suspension contact net system and is used for clamping and fixing the contact line and carrying and transmitting traction current. The busbars are rigid beams suspended directly above the track by spaced apart support means, typically spanning 6-10m. The locomotive is contacted with a contact line clamped by the pantograph and the bus bar above the pantograph to take current, so that the straightness of the bus bar in the vertical direction directly influences the current collection characteristic between the pantograph and the pantograph-catenary, and the highest operation speed of the system is determined to a great extent.

The conventional bus bar is generally in an n-shaped structure, is made of aluminum alloy and has a height of 110mm. The sag of the bus bar is increased due to the fact that the span is enlarged or the rigidity of the bus bar is reduced, the current collection characteristic of a locomotive pantograph is poor, and the operation speed of a system is limited. If the deflection of the bus bar is controlled by reducing the span, the engineering construction cost increases, and thus the higher speed requirement needs to be satisfied by improving the rigidity of the bus bar itself.
