Problems solved by technology

[0003] The existing anti-stealing technology inside the smart meter is relatively mature, but there are still difficulties in implementing the anti-stealing technology outside the meter.
The anti-stealing alarm effect is not good, and the set threshold is too small, which is prone to false alarms
Therefore, the existing anti-stealing scheme based on power comparison is difficult to accurately realize intelligent alarm in practical applications due to technical loss.

Abstract

The invention provides an electricity larceny prevention device which comprises a phase current collecting unit, a transmission current collecting unit, a user current collecting unit and a central processing unit. The phase current collecting unit, the transmission current collecting unit and the user current collecting unit are connected with the central processing unit. According to the technical scheme provided by the invention, the phase current value on a transmission phase line, the output current value on the output side of each power distribution execution unit and the input current value of each single phase user are simultaneously acquired and are compared to judge electricity larceny; the intelligent level of electricity larceny prevention alarm is greatly improved; and the shortcoming of false alarm is avoided.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an anti-stealing device. Background technique [0002] For a long time, the phenomenon of stealing electricity has been a matter of great concern to power companies. Stealing electricity not only causes serious losses to national property, affects the economic benefits of power companies, but also brings a series of hidden safety hazards and social problems, which is extremely harmful. The problem of preventing electricity theft is a long-standing management problem in the power management department. [0003] The existing anti-stealing technology inside the smart meter is relatively mature, but there are still difficulties in implementing the anti-stealing technology outside the meter. The anti-theft alarm effect is not good, and the set threshold is too small, which is prone to false alarms. Therefore, the existing anti-stealing scheme based on power comparison is difficult ...
