An embedded rail transit power supply system

Abstract

The invention discloses an embedded rail transit power supply system which consists of electric conductors and supporting rod assemblies, wherein a current collector assembly in each electric conductor is located in a wear-resistant wall. The current collector is located in the wear-resistant wall, so that influence caused by factors such as natural conditions, train vibration as a result of unevenness of rails and the like is avoided, the current-receiving quality is stable, and accidents of arc ablation of the current collector, the wear-resistant wall and the like are avoided, and meanwhile, the impact effect on the current collector by an end elbow is eliminated, so that the traffic safety is ensured. The electric conductors of the embedded rail transit power supply system can be arranged in a cross manner at the same height, so that cross-through is realized; and fractures are naturally formed at intersections of different lines, so that the purpose of isolating different electric subsections is achieved, thereby facilitating the whole line layout.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices and transportation, and in particular relates to an embedded rail transit power supply system. Background technique [0002] Rail transit is a way of transporting people using rail trains. According to the different ways of rail trains to obtain current, the current rail transit power supply mainly includes overhead catenary power supply and catenary rail power supply. The contact line of the overhead catenary power supply is located above the vehicle and is supported by pillars, catenary cables, hanging strings, etc. The carbon slide plate of the pantograph on the top of the rail train contacts the contact line to obtain current; the contact rail and accessories of the catenary power supply are located at On the side of the bottom of the vehicle, the contact rail and accessories are supported by insulating brackets, and the carbon slide plate of the collector shoe on the side of the r...

AI Technical Summary

Problems solved by technology

Due to the influence of factors such as the installation accuracy of the overhead catenary, natural conditions (such as excessive shaking of the catenary due to strong winds, failure to receive power due to icy rain and snow), and train vibration caused by track unevenness, the carbon slide of the pantograph is in contact with the overhead catenary. There are large fluctuations in the contact force between the wires, which leads to unstable quality of current receiving, and accidents such as arc ablation of overhead contact wires and pantographs, which affect driving safety

In the contact rail power supply mode, there is also a phenomenon of unstable current receiving quality between the carbon slide plate of the collector shoe and the contact rail, and when the collector shoe passes through the fracture, it impacts with the end elbow, which causes an arc and causes ablation End elbows and collector shoes
