Embodiment Construction

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0034] refer to figure 1 , the preferred embodiment of the present invention provides a remote anti-stealing device for remotely alarming the stealing behavior on the power supply line, the remote anti-stealing device includes a phase current acquisition unit, a user current acquisition unit and a stealing The judging unit, the phase current collecting unit and the user current collecting unit are all communicated with the power stealing judging unit. Among them, the phase current acquisition unit is used to collect the phase current value on the output phase line of the power supply unit, and output the collected phase current value to the power stealing judgment unit; the user current acquisition unit is used to collect all users who are powered b...

Abstract

The invention discloses a remote electricity larceny prevention device and a remote electricity larceny prevention method. The electricity larceny prevention device comprises a phase current collecting unit, a user current collecting unit and an electricity larceny judging unit, and the phase current collecting unit and the user current collecting unit are respectively in communication with the electricity larceny judging unit. The phase current collecting unit is used for collecting a phase current value on an output line of a power supplying unit and outputting the collected phase current value to the electricity larceny judging unit. The user current collecting unit is used for colleting partial current values, of all users, of the power supplying unit, wherein the power supplying unit supplies power to the users through output phase lines, and the user current collecting unit outputs the partial current values of the users to the electricity larceny judging unit. The electricity larceny judging unit judges whether electricity larceny occurs on power supplying circuits through comparison of the sums of the phase current value and the partial current values. According to the remote electricity larceny prevention device and the remote electricity larceny prevention method, whether electricity larceny occurs on the power supplying circuits is judged through a different value of the sums of the phase current value and the partial current values, the intelligent level of electricity larceny prevention warning is greatly improved, and the defect of false warning is avoided.

Description

technical field [0001] The invention relates to the field of electricity metering control, in particular, to a remote anti-stealing device and an anti-stealing method. Background technique [0002] The problem of anti-stealing electricity is a long-standing management problem in the power management department. The existing intelligent anti-stealing technologies can be summarized into two categories: [0003] One is the anti-stealing technology inside the meter. This technology is mainly to prevent illegal attacks on the meter from the outside. It is relatively perfect in today's smart meters. Evidence; the second category is aimed at anti-stealing electricity technology outside the ammeter. The existing technical scheme is: compare the sum of the electricity collected by each sub-meter with the electricity collected by the main meter, and subtract the electricity of each sub-meter from the total meter. The difference value is used to judge whether there is electricity stea...
