Problems solved by technology

[0002] A voltage transformer (TV) is a sensor for measuring and measuring instruments to obtain primary voltage information, that is, for a metering device, it is very important whether the wiring of the voltage transformer is correct. If there is a wrong wiring, the value of the metered electric energy will change and cannot be normal. Metering, even impossible to measure, will cause damage to instruments and equipment in serious cases; what is more serious is wrong wiring at the transformer, which is likely to cause equipment damage or personal injury accidents
The current training equipment mainly includes real equipment consistent with the actual equipment on site and intelligent simulation training equipment, but these two types of equipment have serious deficiencies in training:
The most obvious shortcomings are that failures cannot be reproduced, it is not convenient to learn the principles, the training efficiency is extremely low, and the lack of comprehensiveness and theoreticalness of professional knowledge
[0004] 2. The existing intelligent simulation training system: the boring and monotonous human-machine interface lacks a sense of reality, the most prominent problem is the poor consistency with the site, and the operation training of installation and wiring cannot be carried out
The trainers cannot fully understand the wiring of the device as a whole, and its internal structure is very different from that of the site, so it cannot arouse the trainers' strong interest in learning, and they cannot actively understand and learn the situation and reasons for the wrong wiring on site
