Problems solved by technology

[0003] (1) The working space is small, the internal space is about 2300mm*2300mm*2300mm, which cannot truly reproduce the environment of the real power distribution system
[0004] (2) The training function provided is single, and the comprehensive teaching platform can only be used for simple wiring and installation training, and the basic theory of power supply and distribution technology cannot be , such as the design of the small system power supply and distribution system, the calculation of the load, the selection of wires and switching appliances, etc., are integrated into the training device
[0005] (3) The degree of intelligence is low. The comprehensive teaching platform only provides a wiring operation platform, and there is neither wire and switch electrical specification selection content, nor automatic scoring function
[0006] (4) Large wire consumption is required. When using this comprehensive teaching platform for wiring training, the used wires can hardly be reused each time. It is very uneconomical from the perspective of training economy
