Problems solved by technology
[0003] At present, in various colleges and universities, models are used for teaching. Although it is intuitive, the internal structure, working status, and system functions cannot be displayed; the use of physical systems increases the cost of colleges and universities. Also due to the high voltage level, it is impossible to power on for system functions. Even if the school provides the power supply with the above voltage regardless of the cost, there is still a very large safety hazard due to the lack of knowledge and practical skills of the students; it is even impossible to provide such a large load for the system to demonstrate its functions; in summary The two teaching methods currently used by colleges and universities cannot demonstrate the system functions, nor can they simulate and reproduce faults, nor can they guide students to troubleshoot faults

The invention discloses a training platform for a subway traction substation system, which belongs to the field of training for a subway substation system. The training platform for the subway traction substation system includes the first medium-voltage switchgear that uses AC380V civilian voltage instead of the AC35KV voltage of the subway traction substation system for power supply. The first medium-voltage switchgear is electrically connected with a traction transformer. The traction transformer is electrically connected to a rectifier cabinet, the positive terminal of the rectifier cabinet is connected to the catenary through the DC incoming cabinet and the DC feeder cabinet in turn, and the negative terminal of the rectifier cabinet is connected to the return rail through the negative cabinet; in the present invention, the highest The voltage level is set at AC380V, which is the level of domestic production and civil electricity consumption, that is, the AC380V voltage is used instead of the original AC35kV voltage to supply power to the first medium-voltage switchgear and the second medium-voltage switchgear, through the first medium-voltage switchgear, traction The transformer and rectifier cabinet are set to DC48V on the DC voltage side of the DC incoming cabinet and the negative cabinet, that is, DC48V is used instead of DC1500V to ensure the voltage level and ensure the safety of use.
Description
technical field [0001] The invention relates to the technical field of subway substation system training, in particular to a subway traction substation system training platform. Background technique [0002] The subway traction substation system is the core of the subway, and it is the basic condition to provide energy for subway operation and ensure the safe and stable operation of the subway. At present, the basic principles of subway traction substation systems of various brands are similar, and the performance is mature and stable. The system provides feasibility, and its composition can be divided into two parts: traction substation; step-down substation, whose traction substation includes: the first medium voltage switchgear, traction transformer, rectifier, negative cabinet, DC screen , rail potential limiting device, isolating switchgear; the step-down substation includes: the first medium-voltage switchgear, step-down transformer, low-voltage power distribution pane...
