Anti-theft and anti-prying device for power transformer

Abstract

The invention relates to the field of transformers, in particular to a power transformer anti-theft and anti-prying device which comprises a main body, a placement mechanism, an oil adding mechanism,a triggering mechanism, an oil return mechanism and a filtering mechanism. Through the arrangement of the placement mechanism, the main body can be conveniently and horizontally placed; the heat-conducting medium in the transformer can completely cover the electrical components; through the arrangement of the triggering mechanism, an illegal dismounting signal can be conveniently transmitted to communication equipment of an operator in time; therefore, the risk that the transformer is stolen is reduced; due to the arrangement of the oil adding mechanism, enough oil can be conveniently reservedin the main body at a time; frequent secondary addition is avoided; the oil pressure in the main body is reduced by arranging the oil return mechanism; the pressure intensity in the main body is ensured to be always in a reasonable range, so that the main body is prevented from being expanded and broken by the heat-conducting medium, the returned heat-conducting medium is conveniently filtered through the arrangement of the filtering mechanism, impurities are prevented from entering the main body for the second time, and the filtered impurities can be quickly removed.

Description

technical field [0001] The invention relates to the field of transformers, in particular to an anti-theft and tamper-proof device for power transformers. 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. According to the purpose, it 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.). Circuit symbols often use T as the beginning...

AI Technical Summary

Problems solved by technology

[0003] Since most of the metals used inside the transformer are relatively high-value materials, transformers placed in the field are easily stolen and sold off. In order to avoid being stolen, the traditional prevention method is mostly to install passive anti-theft anti-theft nets around the transformer. However, this setting method is not convenient for maintenance personnel to overhaul the transformer, and the traditional transformer needs to add heat-conducting medium to it regularly, which increases the labor intensity and workload of the staff
