Electricity stealing prevention device

Abstract

The invention relates to an anti-electricity-stealing device which comprises a phase current acquisition unit installed at the outlet end of a transformer, a user current acquisition unit installed on a terminal user distribution box and an electricity-stealing judgment unit installed in a control center. The electricity stealing judgment unit is in signal connection with the user current acquisition unit and the phase current acquisition unit. A first communication module is arranged in the phase current acquisition unit, and a second communication module is arranged in the user current acquisition unit; the first communication module and the second communication module are in signal connection with the anti-electricity-stealing judgment unit through the mobile internet; the user current acquisition unit comprises an electric meter box, a controller, a spring and a tension sensor are installed in the electric meter box, and the tension sensor is in signal connection with the controller; the controller is in signal connection with the electricity stealing judgment unit; as long as the door of the electric meter box is opened to steal electricity, the tension sensor can transmit a signal to the controller, the controller transmits the received signal to the electricity stealing analysis unit, and the electricity stealing analysis unit can dispatch a person to check.

Description

technical field [0001] The invention relates to the technical field of electric power industry equipment, in particular to an anti-stealing power device. Background technique [0002] In the existing technology, the power consumption of power users is changed to 380 / 220 volts through transformers, and then distributed to various users through distribution boxes. In real life, there are always a small number of people who steal electricity, which makes power companies suffer Loss; in the way of stealing electricity found so far, basically by tampering with the distribution box, so how to design a device that is convenient for the user to observe the power consumption, and can prevent the distribution box from being opened at will, so as to prevent theft Electricity becomes important; needs to be addressed. [0003] The technology closest to the present invention in the existing patents: the name is, a remote anti-stealing device (application number CN202011043779.7); claim 1...

[0002] In the existing technology, the power consumption of power users is changed to 380 / 220 volts through transformers, and then distributed to various users through distribution boxes. In real life, there are always a small number of people who steal electricity, which makes power companies suffer Loss; in the way of stealing electricity found so far, basically by tampering with the distribution box, so how to design a device that is convenient for the user to observe the power consumption, and can prevent the distribution box from being opened at will, so as to prevent theft Electricity becomes important; needs to be addressed

[0003] The technology closest to the present invention in the existing patents: the name is, a remote anti-stealing device (application number CN202011043779.7); claim 1 of this invention is: "a remote anti-stealing device, characterized in that , including: an electric meter box, the electric meter box includes a door and a box body detachably connected with the door; a circuit board, the circuit board is arranged in the electric meter box, and the main control board is arranged on the circuit board device, the main controller is used to communicate with the remote terminal; a locking mechanism, the locking mechanism is used to connect the box door with the box body; an anti-stealing mechanism, the anti-stealing mechanism is installed on On the box, the anti-stealing mechanism communicates with the main controller on the circuit board; when the box door is closed, the anti-stealing mechanism can contact the locking mechanism, The anti-stealing mechanism can not send an alarm signal under the control of the main controller. When the box door is opened, the anti-stealing mechanism is separated from the locking mechanism, and the anti-stealing mechanism It can send an alarm signal under the control of the main controller”; this invention has the following disadvantages: the structure is complicated to realize simple functions, and there is suspicion of using abnormal applications;

[0004] There is also an application number CN201721584595.5 2 in the existing patent, which is called a power metering box with anti-stealing function. This patent only raises the problem of lightning protection, and there are no specific anti-stealing measures, which need to be improved;
