Electricity stealing prevention device aiming contact electricity stealing and noncontact electricity stealing

Abstract

The invention relates to an electricity stealing prevention device aiming contact electricity stealing and noncontact electricity stealing. The electricity stealing prevention device comprises a power supply, a strong magnetism monitoring module, a high frequency monitoring module, an entrance guard monitoring module, an alarm module and an alarm monitoring terminal. The power supply is used for supplying power to the whole device. The strong magnetism monitoring module is used for detecting a strong magnetism signal and transmitting the strong magnetism signal to the alarm module. The high frequency monitoring module is used for detecting a high-frequency signal and transmitting the high-frequency detection signal to the alarm module. The entrance guard monitoring module is used for detecting an entrance guard signal of an electric energy metering box and transmitting the detected entrance guard signal of the electric energy metering box to the alarm module. The alarm module is used for respectively receiving the strong magnetism signal, the high-frequency detection signal and the entrance guard signal of the electric energy metering box and outputting an alarm signal to the alarm monitoring terminal via a wireless mode so as to perform detection alarm. Automatic inspection and alarm for conventional electricity stealing, wireless high-frequency interference electricity stealing and strong magnetism interference electricity stealing can be realized.

Description

technical field [0001] The invention relates to a teaching device for education and training in the electric power industry, in particular to an anti-stealing device for contact-type electricity theft and non-contact electricity theft. Background technique [0002] Anti-stealing electricity is a very important task in the power marketing work. The State Grid Corporation has invested a lot of manpower and material resources in anti-stealing electricity prevention, and has achieved a lot of results. It has already been able to change various wirings in general. Carry out effective prevention. However, with the development of technology, the ways of stealing electricity driven by interests have also become diversified. At present, the most hidden ways of stealing electricity that cannot be prevented by the State Grid Corporation of China mainly include: strong magnetism Stealing power and wireless high-power high-frequency stealing are two methods of immovable lead sealing of t...
