Description

Analog meter box

technical field

The utility model relates to a teaching simulation device for an electric power system, in particular to a simulation electric meter box, which is suitable for indoor teaching and training.

Background technique

With the popularization of smart energy meters, the behavior of stealing electricity is becoming more and more rampant and there are various methods of stealing electricity, especially the high-tech methods of stealing electricity are hard to guard against, such as installing high-power wireless jammers or high-frequency shocks near the meter box device etc. As a major in power system electricity inspection, there is still a gap in dealing with new high-tech means of stealing electricity, which will cause a lot of direct economic losses to power supply companies and affect the corporate image at the same time. Therefore, it is necessary to study the corresponding countermeasures for the new stealing means of smart energy meters. However, power system maintenance personnel cannot carry out relevant operation exercises, so they lack the practical hands-on opportunity to deal with this kind of stealing behavior, which makes them unable to accurately judge the method of stealing electricity and quickly eliminate the stealing behavior.
