Description

technical field

[0001] The invention relates to the technical field of electrician teaching and training, in particular to a low-voltage power supply system fault diagnosis training device. Background technique

[0002] In the field of electrician teaching and training technology, especially the teaching of power supply system fault analysis, due to the lack of corresponding training devices to reproduce the phenomena and parameters before and after fault repair, it can only be completed by means of logical analysis and inference based on theory. The theoretical basis and practical experience requirements of students and trainees are relatively high, the teaching is difficult, and the teaching process is relatively boring. Therefore, this kind of teaching is difficult and inefficient. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a low-voltage power supply system fault diagnosis training device, a functional el...
