Abstract

The invention relates to a simulated electric meter box which comprises a box body. An anti-interference glass film is arranged on the outer surface of the box body, three current transformers, a circuit breaker, an intelligent electricity meter and a loading power source are arranged in the box body, the three current transformers are connected with the circuit breaker, the intelligent electricity meter and the loading power source respectively, the circuit breaker, the intelligent electricity meter and the loading power source are connected with one another, and the loading power source is composed of a power source and a load. By means of the simulated electric meter box, the ability of preventing and analyzing electricity theft and judging and solving problems of electricity utilization inspectors can be improved through teaching.

Description

technical field [0001] The invention relates to a power system teaching simulation equipment, in particular to a simulation electric meter box, which is suitable for indoor teaching and training. Background technique [0002] 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 ...
