[0002] The problem of electricity theft has long been a "headache" that has troubled the power supply department. It is not only hated by power supply companies, but also seriously affects the stability and harmony of society. In order to prevent electricity theft, power supply companies have adopted a variety of measures, which have played some role, but the effect is minimal. Driven by economic interests, electricity thieves rack their brains and find ways to steal electricity, which not only increases the difficulty of anti-electricity theft work, but also brings challenges.
[0003] Therefore, mastering anti-electricity theft technology is one of the main means of anti-electricity theft training. The traditional anti-electricity theft training content is outdated, the training methods are single, and the training is mainly carried out in the form of traditional preaching and electricity theft case explanation training, which has little effect and is no longer suitable for the needs of modern power grids.
[0004] There are also some anti-electricity theft training devices, such as the Chinese invention patent application with application publication number CN 110009959 A, which provides an all-purpose power supply station training operating system and its anti-electricity theft training circuit. By setting the wiring mode of multiple electric energy meters in the anti-electricity theft training circuit, it can simulate various electric theft methods in the low-voltage power distribution system, so that the trainees of the substation can learn various electric theft principles and the actual circuit structure of electric theft more intuitively. However, the training content provided by the anti-electricity theft training device only includes two-household joint electric theft, zero-fire reverse connection electric theft, and simulated remote control electric theft. The types of electric theft cannot meet the requirements of anti-electricity theft technical training.
[0005] In order to solve the above problems, people have been seeking an ideal anti-electricity theft solution. Summary of the invention
