Electric larceny prevention metering device and electric larceny prevention method thereof

Abstract

The present invention discloses an electric larceny prevention metering device and an electric larceny prevention method thereof. The electric larceny prevention metering device comprises a box which is capable of closing secondary wiring of current transformers, so that electric larceny cannot occur at the position of the secondary wiring. At the same time, each current transformer sleeves an electric conductor, one end of the electric conductor is fixed to a kettle head rod of a transformer, and the electric conductor is not easy to break, so that electric larceny cannot occur at the position of primary wiring, and a pressure wire at the voltage side of the transformer can be omitted. The electric larceny prevention method of the electric larceny prevention metering device can protect the secondary wiring, the primary wiring and the current transformers, in addition, connection points of the above positions are also protected, in this way, through adoption of the electric larceny prevention metering device, the positions where electric larceny is easy to occur can be closed, thereby effectively preventing occurrence of an electric larceny condition.

Description

technical field [0001] The invention relates to the technical field of electricity theft prevention, in particular to an anti-theft electricity metering device and an application method thereof. Background technique [0002] With the widespread application of power equipment, electricity bills have become a relatively large expense for enterprises. Some companies deliberately steal electricity to achieve the purpose of paying less or no electricity bills. Even professional organizations that steal electricity for profit have emerged in society to provide power supply companies. cause greater losses. Such as figure 1 As shown, at present, the power supply enterprises generally install the A-phase current transformer 1a, B-phase current transformer 1b and C-phase current transformer 1c for measuring electric energy in the switchboard, and let the A-phase voltage line on the low-voltage side of the transformer 2a, B-phase voltage line 2b and C-phase voltage line 2c pass throu...

AI Technical Summary

Problems solved by technology

The disadvantage is that the current transformers, voltage lines, primary current lines of current transformers, secondary current lines of current transformers, and voltage and current contacts are all exposed, leaving large technical loopholes for illegal enterprises to steal electricity, making There are no technical obstacles to stealing electricity, and no traces are left after stealing electricity, so it is difficult to find out the evidence of electricity stealing
