Description

Technical Field

[0001] The utility model relates to the technical field of monorail vehicles, in particular to an electrical cabinet for a monorail vehicle. Background Art

[0002] Straddle-type monorail trains ride on rubber tires on track beams, with the majority of the vehicle's underbody occupied by tracks, bogies, and guide wheels. Monorail vehicles are smaller than subway cars, leaving less space for equipment installation and wiring. Existing monorail wiring systems achieve electrical connections by routing bundled wiring harnesses onto the vehicle body.

[0003] The existing rail vehicle electrical layout: Electrical components and host equipment for each system are centrally installed in electrical cabinets at the ends of the vehicle, resulting in typically tall and bulky cabinets. These cabinets are connected to various functional devices installed on the vehicle via through-body and underframe wiring harnesses. The cabinets and harnesses are connected using intermediate connectors. The centralization of components and host equipment results in an increase in cabling, requiring more space for wiring and harness transfers. Jumper cables between vehicles are typically located on the lower exterior of the vehicle, and junction boxes are suspended from the lower sections of the vehicle bodies at both ends for jumper connections.

[0004] However, in the above-mentioned existing method, most of the space at the bottom of the vehicle is occupied by tracks, bogies, and guide wheels, and the jumper wires are not suitable for being set under the vehicle. The space in the monorail vehicle compartment is small, and some equipment needs to be installed on the vehicle, further squeezing the available space in the compartment and making it less suitable for use.
