Anti-theft monitoring and alarm system for transformer

Abstract

The invention discloses an anti-theft monitoring and alarm system for a transformer. The system is composed of an anti-theft alarm device installed beside a transformer. A central processing unit, a wireless receiving module, a wireless sending module, a power failure detection module, and an alarm module are arranged inside the anti-theft alarm device. The anti-theft alarm device has a wired anti-theft interface; a wired sensing line is arranged outside the wired anti-theft interface and winds around a power supply transformer housing; and a vibration detector is arranged at a power supply transformer. The central processing unit is used for processing a received power failure signal and a received mobile signal and sending the processed signals to a remote terminal and the alarm module by the wireless sending module. According to the system, when a circuit becomes abnormal, someone approaches a transformer station, a transformer is destroyed, or a transformer is moved, warning information can be sent to the police officer timely to prevent stealing of the transformer.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a transformer anti-theft monitoring and alarm system. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc., and can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators) , mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers, reactors, transformers, etc.), which are widely used in power systems, throughout urban and rural ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that it is installed in the wild and unattended, and there are no good anti-theft measures and measures, so some criminals will steal the coils in the transformer, and after the transformer is stolen, it will cause a large-scale power outage , has brought great harm to people's lives, and at the same time, it has also caused damage to the country's economy, especially in remote mountainous areas, making people's lives very inconvenient. The purpose is to provide anti-theft monitoring and alarm systems for transformers, which can When there is an abnormality in the circuit or someone is close to the transformer voltage or the transformer is damaged or moved, an alarm will be issued to notify the police in time to prevent the transformer from being stolen. Deterrent effect to prevent its further behavior, but also to record the scene environment, so as to investigate the scene environment afterwards
