A high-power charging device for trams

Abstract

The invention relates to high-power charging equipment of a tramcar. The high-power charging equipment comprises a rectifier transformer (1), a charging device cabinet (2), an output isolation cabinet (3), a master control system (4) and a vehicle position monitoring device (5), wherein the rectifier transformer, the charging device cabinet and the output isolation cabinet are electrically connected in sequence; the rectifier transformer converts alternating voltage input from a high-voltage supply network into input voltage suitable for the charging device cabinet; the charging device cabinet is used for generating charging currents or charging power needed by a vehicle-mounted super-capacitor energy storing device through the input voltage input from the rectifier transformer; the output isolation cabinet is used for outputting the charging currents or the charging power generated by the charging device cabinet to the tramcar and achieving downlink and uplink charging switchover of the tramcar; the master control system is in signal connection and communicating junction with the rectifier transformer, the charging device cabinet, the output isolation cabinet and the vehicle position monitoring device. The high-power charging equipment can be automatically adjusted according to the operating state of the super-capacitor energy storing device to achieve quick and safe charging.

Description

technical field [0001] The invention relates to a high-power charging device for trams based on a novel supercapacitor. Background technique [0002] With the development of urban rail transit and supercapacitor technology of new energy storage devices, it has become a general consensus that a new generation of energy-saving and environmentally friendly trams represented by supercapacitor energy storage trams is an inevitable trend in the development of urban rail transit. The charging equipment provides energy supply for the supercapacitor energy storage device of the tram, which is an important basic support system for the new tram. The development of high-power charging technology has a decisive impact on the development of trams. [0003] The use of electric drive for trams belongs to green transportation. The existing trams mainly use the overhead line network to provide power, but the overhead line network for power supply has an impact on the landscape in some specif...
