Low-voltage electricity larceny analyzer and use method

Abstract

The invention relates to a low-voltage electricity larceny analyzer and a use method, and belongs to the technical field of power supply. According to the technical scheme, a real-time clock circuit (2), a power supply circuit (3), a FLASH memory circuit (4), a Bluetooth module circuit (7) and a 4G communication module circuit (8) are respectively connected with an embedded microcontroller (1), and the embedded microcontroller is connected with a concentrator through an RS-232 interface circuit (5) and an RS-485 interface circuit (6). The analyzer has four main functions of checking the cover opening record of the electric energy meter, checking the current loss of the electric energy meter, checking the incoming and outgoing line current abnormity of the electric energy meter and checking the clock out-of-tolerance, data abnormity is judged by adopting a method for calculating the standard deviation through Bessel and Pearl algorithms, and compared with household-by-household checking, the daily workload of workers is greatly reduced, moreover, problems in the operation of the electric energy meters of the users in the transformer area can be found and processed in time, so that the line loss is effectively reduced, and the legal electricity utilization environment is standardized.

Description

technical field [0001] The invention relates to a low-voltage power stealing analyzer and a use method thereof, belonging to the technical field of power supply. Background technique [0002] Power resources are widely used in today's society due to their convenience and cleanliness. However, with the development of society and economy and the increase of electricity consumption, the problem of electricity theft has become more and more prominent. billion. Stealing electricity has greatly increased the line loss rate in the station area and disrupted the normal order of electricity consumption. This not only plagues the development of power supply companies, but also seriously affects the country's economic construction and social stability. serious threat. What's more serious is that with the continuous upgrading of electricity stealing technology, the phenomenon of electricity theft has not only not been curbed, but has become more and more serious. It is getting bigger...

Problems solved by technology

In underdeveloped areas such as Southeast Asia and Africa, electricity theft is also very common. These areas generally adopt the anti-theft and on-site inspection methods of our country in the 1980s and 1990s, and there are no better anti-theft measures.
