Problems solved by technology

[0005] The purpose of the present invention is to provide a power receiving device and system for urban rail transit, which is used to solve the problem of affecting urban landscape and safety in the way of erecting the power supply catenary throughout the whole process of the prior art, for example, erecting high-voltage catenary at key intersections , the height of passing vehicles is limited. When some vehicles transport materials, it is easy to scratch the catenary, resulting in electric shock, and there are certain safety hazards.

Abstract

The invention discloses a powered device and system for urban track traffic. The device comprises a power supply, a power supply track connected with the power supply and a transponder. The power supply track comprises multiple power supply sub-tracks insulated from one another. The transponder is electrically connected with all the power supply sub-tracks and used for receiving control signals sent by a train to control connection between the power supply sub-tracks below the train and the power supply so as to supply power to the train. In the powered device and system for urban track traffic, when the train passes, the power supply sub-tracks below the train are controlled to be connected; due to the fact that all the power supply sub-tracks are insulated from one another, it can be guaranteed that no electrified part exists on the periphery of the train, and the safety of the powered device and system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rail transit power supply, in particular to an urban rail transit power receiving device and system. Background technique [0002] Urban rail transit mainly refers to urban subway, urban express rail, light rail, tram, etc. Urban rail transit generally requires continuous power supply from the power system to ensure its normal operation. [0003] In the prior art, urban rail transit generally adopts a continuous power receiving method, and the overhead catenary is used to continuously provide electric energy for trains. figure 1 A structural schematic diagram of catenary power supply in the prior art, such as figure 1 As shown, in the prior art, a continuous power supply catenary 14 needs to be erected throughout the whole process above the train 12, and a pantograph 13 is installed on the roof of the train 12, and continuous power is received through the contact between the pantograph 13 and the catena...
