Embodiment Construction

[0024] The anti-stealing detection device and the anti-stealing analysis system of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown in the figure, it is a composition structure of a watch area anti-stealing detection device. The device is composed of a parameter sampling circuit 1, a synchronous circuit 2, a single-chip microcomputer circuit 3, a memory circuit 4, a power supply circuit 5 and the like. Parameter sampling circuit 1 is provided with N+1 sampling lines according to the scale of a meter area, that is, the sampling lines of a main meter (electric energy meter on the power supply side) and N electric energy meters on the user side. The specific sampling circuit is divided into voltage parameter acquisition The circuit 7 and the current parameter acquisition circuit 8, the voltage parameter acquisition circuit 7 and the input terminal of the power supply circuit are conn...

Abstract

The invention discloses a meter area electricity larceny prevention detection device and an electricity larceny prevention analysis method. The detection device comprises parameter sampling circuits,a single-chip microcomputer circuit and a power supply circuit. The parameter sampling circuits are circuits for sampling a main meter and N user meters in a meter area at the same time, each samplingcircuit is controlled by a synchronous circuit, so voltage and current parameters of N + 1 meters (N user electric energy meters and a power supply electric energy meter) can be sampled at the same time, and data obtained through sampling is processed and calculated by the single-chip microcomputer circuit. The electricity larceny prevention analysis method is divided into a voltage comparison part, a current comparison part and a power consumption comparison part; power calculation is carried out on voltage and current parameters of each electric energy meter in the user meter area, the power parameters are obtained through calculation, superposition comparison calculation is carried out on the voltage, current and power parameters, and whether an electricity larceny phenomenon occurs ornot is judged according to a calculation result. The beneficial effects of the detection device are that the device can specifically judge which phase and which household are abnormal in power utilization, and the inspection range of inspectors is reduced.

Description

technical field [0001] The invention belongs to the technical field of power supply, and in particular relates to a watch area anti-stealing electricity detection device and an anti-theft electricity analysis method in the field of power supply technology. Background technique [0002] Stealing electricity has always been a difficult problem in the field of power supply technology. Stealing electricity has seriously violated the rights and interests of power supply companies, disturbed the order of power supply and consumption, and led to high line loss. For a large number of residential users stealing electricity, it is very difficult for the power supply department to investigate and deal with it. In the past, electricity theft inspections were mostly carried out in the form of random inspections and "squatting spots". The inspection accuracy is not high and the error is relatively large. With the continuous emergence of new electricity stealing methods, this detection m...
