Problems solved by technology

[0002] At present, in the process of providing power services in the power system, there is often a problem that the power consumption is inconsistent with the actual consumption.
The reason is that, on the one hand, it is caused by the loss of the transformer and the line itself, and on the other hand, it is caused by illegal electricity theft.
There are many ways to illegally steal electricity, but the basic methods are all aimed at the watt-hour meter. By modifying the watt-hour meter, or even taking the method of damaging the watt-hour meter to achieve the purpose of illegal electricity theft, it is difficult for the power supply department to find out the stealing behavior caused serious economic losses to the country

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] An anti-theft system, such as figure 1 As shown, it includes electronic transformers distributed and installed on the power cable between the high-voltage line and the transformer, electronic transformers installed on the power cable between the transformer and the user's watt-hour meter, line monitoring terminals connected to the electronic transformer, and remote remote data center. The electronic transformer can be connected to the line monitoring terminal by means of short-distance wireless network, RS485 serial bus or optical fiber, and the line monitoring terminal is connected to the remote remote data center through 3G network, LAN network or optical fiber network. Each part of the system is described below:

[0022] like figure 2 As shown, the electronic transformer includes a Hall sensor, a signal conditioning circuit, an analog-to-digital...

Abstract

The invention relates to an electricity larceny prevention system. The electricity larceny prevention system is mainly technically characterized by comprising first electronic transformers, second electronic transformers, a line monitoring terminal, and a remote data center; the first electronic transformers are mounted on a power cable between a high-voltage line and a transformer, and the second electronic transformers are mounted on a power cable between the transformer and a user's electricity meter; the electronic transformers are connected with the line monitoring terminal in a wired or wireless manner, the line monitoring terminal is connected with the remote data center in a wired or wireless manner, and the remote data center is used to analyze data for achieving the function of electricity larceny prevention. The electricity larceny prevention system is reasonable in design; the electronic transformers mounted on the power cables are used with the line monitoring terminal and the remote data center to achieve the function of electricity larceny prevention; transforming efficiency of the transformer can be detected fast to allow the aged and failed transformer to be replaced timely and avoid electricity waste, and energy conservation and emission reduction are achieved; the electricity larceny prevention system has the advantages of safety, reliability, high stability, convenience in use and the like.

Description

technical field [0001] The invention belongs to the technical field of power cables, in particular to an anti-stealing system. Background technique [0002] At present, in the process of providing power services in the power system, there is often a problem that the power consumption is inconsistent with the actual consumption. The reason is, on the one hand, the loss of the transformer and the line itself, and on the other hand, the illegal power theft. There are many ways to illegally steal electricity, but the basic methods are all aimed at the watt-hour meter. By modifying the watt-hour meter, or even taking the method of damaging the watt-hour meter to achieve the purpose of illegal electricity theft, it is difficult for the power supply department to find out the stealing behavior The existence of it has caused serious economic losses to the country. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior ...
