Power device and system of aerial train, aerial train and aerial train system

Abstract

The invention belongs to the field of aerial train power, and particularly provides a power device and system of an aerial train, the aerial train and an aerial train system. The problem that in the prior art, an aerial train can not give consideration to fault resistance capacity and continuous operating capacity of a power supply system is solved. The power device of the aerial train comprises a driving device of the aerial train and a power source unit used for supplying power to the driving device. The power source unit comprises a super-capacitor unit and a first charging device. The super-capacitor unit is electrically connected with the driving device and used for driving the driving device. The power source unit further comprises a rechargeable battery unit, a second charging device and a switching control unit. The super-capacitor unit and the rechargeable battery unit are electrically connected with the driving device through alternative switching of the switching control unit. The power device of the aerial train adopts the super-capacitor unit and has the advantages of being low in weight, high in capacity, fast in charging and the like, the rechargeable battery unit is further arranged, and switching is conducted between the two power units according to situations, so that the power supplying system is safer and guaranteed.

Description

technical field [0001] The invention belongs to the field of sky train power, and specifically provides a power device and system of a sky train, a sky train and a sky train system. Background technique [0002] The rapid increase of vehicles in modern cities and the relatively congested ground traffic have seriously affected people's travel. As a result, a series of rail transit facilities such as light rail, subway, maglev train and sky rail train have appeared, forming a three-dimensional transportation network. [0003] The sky train is to hang the track on the pillars, and some train cars are suspended on the guide rail in a pendulum type, and travel along the guide rail through the traveling mechanism; some travel along the guide rail. The guide rail setting has the advantages of no road occupation, no damage to the environmental landscape, low noise, safety, low cost, short construction period and less interference to ground traffic during the construction period. ...

AI Technical Summary

Problems solved by technology

The third rail power supply method requires a long laying along the track of the sky train, which is costly, and partial power failure affects the operation of the entire line, and the anti-fault ability is weak

The lithium battery pack is used for power supply. Due to the slow charging characteristics of the lithium battery, in order to ensure the continuous operation of the sky train, it is necessary to equip a battery pack with a large capacity to ensure the continuous running distance. At the same time, it needs to be configured at the station The battery replacement device is used to replace the battery pack. Compared with the third-rail power supply method, although the anti-fault ability has been improved, the weight of the large-capacity battery is heavier, which brings unnecessary energy consumption. At the same time, the time taken for lithium battery replacement Long, and the large number of configurations of spare replaceable lithium batteries also increase the cost
