Anti-theft noise-reduction transformer

Abstract

The invention provides an anti-theft noise-reduction transformer, which adopts two anti-theft schemes including a structure anti-theft scheme and an alarming anti-theft scheme, and two noise reduction designs simultaneously. The upper edge of a tank body of an oil tank is fixedly welded with a tank cover and a winding coil of the transformer is permanently sealed inside the tank body of the oil tank, so that the tank cover can not be opened for stealing winding copper wires under the condition of not damaging a sealed steel-made transformer oil tank structure; meanwhile, by adopting two initiative anti-theft alarming ways including vibration alarming and non-voltage alarming, an anti-theft performance of the transformer is further enhanced. In addition, the two vibration-attenuation and noise-reduction designs are adopted, so that the noise of the transformer is reduced to the greatest extent and the phenomenon of disturbing people by noises is avoided.

Description

technical field [0001] The invention relates to a transformer, in particular to an anti-theft and noise-reducing transformer. Background technique [0002] Power transformers are an important part of the power grid. Ensuring the safe and reliable operation of power transformers is related to all aspects of production and life, and has important social significance. However, as the price of metal materials, especially copper, continues to rise, the problem of theft of power transformers has become increasingly prominent. On the one hand, the box body and box cover of the existing transformer are connected and fixed by fastening bolts. As long as the bolts are loosened and the box cover is opened, the winding coil of the transformer can be easily taken out. Theft and poor anti-theft performance are technical defects; on the other hand, the existing transformer itself does not have an anti-theft device, and the anti-theft facilities installed outside the transformer are not s...

Problems solved by technology

However, as the price of metal materials, especially copper, continues to rise, the problem of theft of power transformers has become increasingly prominent.

On the one hand, the box body and box cover of the existing transformer are connected and fixed by fastening bolts. As long as the bolts are loosened and the box cover is opened, the winding coil of the transformer can be easily taken out. Theft and poor anti-theft performance are technical defects; on the other hand, the existing transformer itself does not have an anti-theft device, and the anti-theft facilities installed outside the transformer are not sensitive and reliable, and the anti-theft effect is not ideal. purpose, at the same time, the transformer in the prior art is noisy and disturbs the people more seriously
