Circuit control structure and battery cabinet for direct-current pure electric small train

Abstract

The invention belongs to the technical field of direct-current electric small trains, and relates to a circuit control structure and a battery cabinet for a direct-current pure electric small train. The circuit control structure comprises a storage battery pack, and the anode output end and the cathode output end of the storage battery pack are connected with a communication control module to forma loop; the positive electrode output end of the storage battery pack is output to the direct-current output module through the discharge relay, the fuse and the anti-reverse diode in sequence, and the direct-current output terminal is grounded; a cooling circuit is connected to a node A between the fuse and the anti-reverse diode; and the communication control module comprises a plurality of connecting ends which are respectively connected with the fuse, the relay coil, the temperature sensor, the discharge relay and the undervoltage protection circuit. According to the battery cabinet, thelow-voltage direct-current stable output function is achieved through the direct-current output module, the under-voltage automatic power-off protection function is achieved through the design of theunder-voltage protection circuit, and the battery cabinet is compact in overall structure, reasonable in component layout and suitable for a narrow-space environment.

Description

technical field [0001] The invention belongs to the technical field of DC electric trains, and relates to a battery cabinet, in particular to a circuit control structure and a battery cabinet for a DC pure electric train. Background technique [0002] With the continuous development of international and domestic tourism, the whole society vigorously advocates "energy saving, emission reduction, and green development", and the market of pure electric sightseeing trains is booming. The pure electric sightseeing train is mainly used in tourist attractions. The whole vehicle is powered by a large-capacity DC power battery and has no exhaust emissions. It has a beautiful appearance, large passenger capacity, and low cost, and is favored by tourists and tourism companies. [0003] At present, pure electric sightseeing trains generally use medium and high-power electric transmission systems. The system contains a variety of electrical components, such as traction converters, batter...

Problems solved by technology

At the same time, limited by the size of the train, it will inevitably lead to insufficient space for the electrical and mechanical layout of the train. Therefore, the structure of the battery cabinet needs to be simplified to meet the requirements of the electrical system for various functions.
