Design And Application Of Electrical Installation And Maintenance Training Equipment For Urban Rail Transit Vehicles

The installation and maintenance of electrical system of urban rail transit vehicles are the key skills of the students of urban rail transit vehicles. The acquisition of skills can not only rely on the teaching of teachers, but also requires a lot of repeated operation and training. Urban rail transit specialty is a new professional. Practice teaching equipment is not perfect. Supporting teaching tools are very limited. In particular, the vehicle electrical system related training equipment are mainly based on perceptual knowledge. Training device is still in use of the original mechanical and electrical professional training device. The teaching equipment with special characteristics is large in size, expensive in price, inconvenient in maintenance and repair. Therefore, it is quite necessary to develop the experimental and practical training equipment which is necessary for the professional skills of rail traffic. It can simulate the real workplace environment, the production of the project into the training teaching system.In this paper, the electrical installation and maintenance training equipment of urban rail transit vehicles are described. The typical circuit in the actual electric system of the urban rail transit vehicle is separated from the system. After simplification and transformation, the appearance and working principle of the actual vehicle circuit are simulated. Make it easy for students to carry out a large number of repeated operation and training. It helps students to carry out professional knowledge learning and practical skills training. It lays the foundation for the students to the electrical installation, maintenance and repair of the urban rail transit vehicles. The paper elaborates the needs of students, schools and enterprises in the training teaching. The function of training equipment should be analyzed, including electric system principle demonstration function, electrical wiring installation planning and training function, electrical single skill training function, electrical wiring and wiring training function and electrical system inspection and maintenance training function. According to the functional requirements, the electrical system of the whole train was analyzed and screened. In the end, the vehicle external illumination circuit is used as the carrier of the training equipment. According to the electric principle diagram of the train, the function and working principle of the external lighting circuit are analyzed and studied. Under the principle of ensuring the safety, practicality, convenience and economy of practical training equipment, the design of equipment circuit, appearance and supporting training teaching materials are designed. The formation of a complete set of vehicle electrical installation and maintenance of experimental training system.At present, the training equipment in this paper has been applied in the teaching of theory and practice and has produced a good teaching effect. As a teacher training equipment and competition training equipment in the teacher training and the development of students play a greater role. If we can get further promotion will have greater social benefits and economic benefits. Hope that through this study, enrich and improve the urban rail transit professional experimental training conditions, improve the quality of personnel training. At the same time, it also hopes to provide ideas and ideas for the development of other training equipment.
