Intelligent electricity-stealing-prevention single-phase electric energy measuring box

Abstract

The invention relates to an intelligent electricity-stealing-prevention single-phase electric energy measuring box comprising a measuring box body and an intelligent electricity-stealing prevention device. The intelligent electricity-stealing prevention device consists of a microprocessor, a power supply module, a leakage current detection module, an incoming line side temperature acquisition module, an electric meter box total-electricity measuring module, an information storage module, an unpacking event recording module, a watchdog module, a display prompting module, an interface module, and a one-way meter reading module, wherein the modules except the microprocessor are in communication connection with the microprocessor; the interface module and an external terminal are in communication connection; the one-way meter reading module and a one-way meter are in communication connection; and the power supply module, the leakage current detection module and the electric meter box total-electricity measuring module are connected with a power grid electrically. According to the invention, illegal opening of an electric meter box can be avoided; and electricity stealing can be prevented. The box has various communication functions and is compatible with a centralized meter reading system; and because of the complete functions, using demands can be satisfied. Moreover, the overall system is an open system; and when the temperature exceeds a set value, alarming is carried out timely, so that the box can be used safely and reliably.

Description

technical field [0001] The invention relates to a single-phase electric energy metering box, in particular to an intelligent anti-stealing single-phase electric energy metering box, which belongs to the field of electric power monitoring devices. Background technique [0002] Stealing electricity has always been a major problem for power supply enterprises. Stealing electricity not only causes serious economic losses to the country and the collective, but also restricts the improvement of economic benefits. With the rapid development of science and technology, the way and technology of stealing electricity are getting more and more sophisticated, and it is difficult for the traditional anti-stealing methods to achieve the desired effect. [0003] The usual means of stealing electricity is to illegally open the metering box and then illegally adjust the meter. Traditional meter boxes generally use mechanical built-in locks, which can be easily opened by electricity thieves. ...
