Oil-immersed transformer containing treating device

Abstract

The invention belongs to the field of power distribution transformers, and particularly relates to an oil-immersed transformer containing a treating device. In the using process, a gaseous cavity inside a shell of the transformer can be eliminated, the performance of the transformer is improved, due to the fact that gaseous impurities such as water vapor generated by heating of water can rise along an oiling cylinder and an exhaust sleeve and exhaust from an exhaust hole in the using process of the transformer, simultaneously, oiling towards the interior of the transformer from the interior ofan oiling pipe is performed, so that old transformer oil can enter into the interior of a purification device from an oil outlet of the exhaust sleeve, purification treatment is carried out on the old transformer oil, circulation purification application of the transformer oil is realized in a sealed environment, and the content of maintenance work of the transformer is reduced.

Description

technical field [0001] The invention belongs to the field of distribution transformers, in particular to an oil-immersed transformer with a processing device. Background technique [0002] The oil-immersed transformer has good insulation and safety. It realizes the isolation and protection of the transformer by immersing the transformer in insulating and flame-retardant transformer oil. Its main structure includes the transformer body and the transformer shell surrounding the outside of the transformer body. Usually, in order to prevent external gas or other impurities from entering the inside of the transformer, the oil-immersed transformer is a sealed structure, and only has an oil filling device for replacing and filling the transformer. And regulating devices such as transformer respirators. However, in actual use, it is impossible to completely avoid the entry of various reasons including external impurities into the transformer, including various moisture and various ...

AI Technical Summary

Problems solved by technology

However, in the actual use process, it is impossible to completely avoid various reasons such as external impurities entering the interior of the transformer, including various moisture and various polar particles.

The moisture comes from the moisture contained in the transformer oil itself and the moisture that enters the transformer through the air and tiny gaps during long-term use. Various types of moisture accumulate inside the transformer, and are affected by the heat of the transformer body to produce steam or (oil-water mixed) water emulsion. The insulation and cooling effect of transformer oil is reduced, resulting in the exposure of part of the structure of the equipment to the transformer oil, the loss of insulation protection and cooling effect, and the effectiveness and safety of the equipment are reduced
