Low-voltage electricity larceny preventive switch and electricity larceny preventive method thereof

Abstract

The invention discloses a low-voltage electricity larceny preventive switch which comprises a voltage sampling module, a current sampling module, a power supply module, a controller module, a clock module and a communication module. The low-voltage electricity larceny preventive switch is connected in series to a power line and positioned in the front end of an electric energy meter; the power supply module supplies power; the voltage sampling module samples a power line voltage signal and uploads the power line voltage signal to the controller module; the current sampling module samples a power line current signal and uploads the power line current signal to the controller module; the clock module provides a clock signal; the controller module receives the voltage and current sampling signals to measure electric energy and communicates with the outside through the communication module. The invention also discloses an electricity larceny preventive method of the low-voltage electricitylarceny preventive switch. The low-voltage electricity larceny preventive switch capable of metering and communication is additionally arranged in the front of the electric energy meter, metering data of the low-voltage electricity larceny preventive switch is compared with that of the electric energy meter, so that an electricity larceny behavior can be prevented, discovered and uploaded; and the switch and method are high in reliability and electricity larceny detecting efficiency.

Description

technical field [0001] The invention specifically relates to a low-voltage anti-stealing switch and an anti-stealing method thereof. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. [0003] However, with the increase of electricity consumption, the cost of electricity charges also gradually increases. In order to achieve the purpose of paying less or not paying electricity bills, a small number of lawbreakers have begun to steal electricity. At present, there are many ways to steal electricity, such as shorting the secondary current transformer used to measure electric energy, so that the current collected by the electric energy meter is smaller than the actual current value, or short-circuiting the outgoing line and incoming line of th...
