Training device for low-voltage metering and electricity-stealing prevention

Abstract

The invention provides a training device for low-voltage measurement electricity-stealing opposition, which comprises an isolation transformer, an electricity-stealing simulator, an electric energy meter, a communication module and a computer, wherein the isolation transformer and the electric energy meter are connected with the wire incoming end and the wire outgoing end of the electricity-stealing simulator respectively; the computer is communicated with the electricity-stealing simulator by the communication module so as to control the electricity-stealing simulator to simulate different electricity-stealing modes; the electricity-stealing simulator comprises a switching power supply, a 485 communication module, a single-chip machine control circuit and a relay matrix circuit; the relaymatrix circuit comprises a relay driving chip and a plurality of relays; the switching power supply is connected with the 485 communication module and the single-chip machine control circuit respectively so as to supply power; and the 485 communication module is connected with the single-chip machine control circuit. The device solves the problem that teaching experiment or training means for low-voltage measurement electricity-stealing opposition lags behind and has the advantages of safety, reliability and strong practicability.

Description

technical field [0001] The invention relates to an experimental device or a teaching training device for skill training and technical appraisal of technical and management personnel in a power supply and distribution system, in particular to a low-voltage measurement anti-stealing power training device.

[0002] Since electricity was discovered and used, it has become an indispensable and important energy source for the survival, development and progress of human society. Almost all human activities are closely related to electricity; with the development of economy, the demand for electricity The expansion of the electricity sales market has stimulated the development of the entire electricity production. However, with the increase in electricity consumption, especially with the establishment of a market economy system, the phenomenon of electricity theft is becoming more and more common throughout the country, and the problem of electricity theft has also become a problem. The problem of stealing electricity not only plagues the development of power companies, but also seriously affects the country's economic construction and social stability. However, due to various subjective and objective reasons, the phenomenon of stealing electricity still exists for a long time and plagues Power supply enterprises; Judging from the various electricity theft cases discovered and handled in recent years, not only the methods of stealing electricity are becoming more and more sophisticated, and the amount of electricity theft is increasing, but some electricity thieves also specifically take advantage of legal loopholes and try to escape. Due punishment; therefore, the prevention and control of electricity theft has become an important issue that cannot be ignored and needs to be solved urgently

[0003] At present, the technical level of power supply inspectors in the power system, especially the rural power grid system, is relatively low, which is far from meeting the requirements for investigating and punishing electricity theft; based on the serious phenomenon of electricity theft, it is urgent for power supply companies to improve power supply inspection and related management. The level of anti-stealing technology of personnel; in the existing technology, the technical training for power supply management personnel to investigate and deal with the phenomenon of stealing electricity, due to the lack of experiments and anti-stealing drill equipment, it is impossible to directly demonstrate the way or means of stealing electricity, but relying on theoretical teaching, which often makes the training less effective
