Novel traction power supply system based on rail traffic sand table model

Abstract

The invention discloses a novel traction power supply system based on a rail traffic sand table model. The two traction power supply modes of an overhead contact line and a contact rail are adopted, wherein according to the power supply mode of the overhead contact line, a semi-compensation suspending device and a full-compensation suspending device are adopted, the combination of soft and hard crossing is adopted by a station, soft crossing is adopted by a vehicle section, the line is provided with equipment like a segmented insulator, an anchoring section joint, a center anchoring section, afeeder line, an electric connector and a return line and various lines, and the signal marks are complete, and are completely identical to those in the actual operating situations. The basic principle and the working operating scene of a rail traffic or railway power supply system can be truly restored to achieve the purpose of educating and teaching students of relevant universities and majors of railway and rail traffic, the purpose of training staff by rail traffic and railway construction and operation units can also be achieved, and the original intention of the design of a sand table istruly embodied.

Description

technical field [0001] The invention relates to a rail traffic simulation sand table system, in particular to a novel traction power supply system based on a rail traffic sand table model. Background technique [0002] The commercial nature of the sand table in the existing rail transit is serious, the power supply method is simple and some businesses aim to make money, not only the cost is high, the structure is simple, the performance is poor, and it cannot restore the real rail transit and railway power supply operation status, let alone achieve For the purpose of education, teaching and training, dry batteries or separate track power supply methods are used commercially, and the catenary is not even erected as a mock project. The irresponsible attitude of the merchants not only makes it impossible for learners to have real access to rail transit and railway scenes, but even causes misunderstandings, completely away from the original intention of using the sand table.
