Protecting device of oil-immersed transformer

Abstract

The invention relates to a protecting device of an oil-immersed transformer. The protecting device comprises a transformer oil tank and a tank cover. A transformer body of the transformer is placed in transformer oil of the transformer oil tank, a heating and radiating integrated device for protecting the transformer is arranged on the outer side of the transformer oil tank, an oil leakage protecting layer is further arranged between the heating and radiating integrated device and the transformer oil tank, the oil leakage protecting layer comprises an outer shell arranged on the outer side of the transformer oil tank, the lower end of the outer shell is in an arc shape, a liquid sensor for sensing whether liquid exists or not is arranged at any position of the lower end of the outer shell, a transformer oil outlet is formed in the lowest end of the outer shell, the transformer oil outlet is controlled by a controller connected with the liquid sensor to be opened and closed, and the controller is further connected with an alarm device. The protecting device is novel in structure, flexible in radiating and heating mode, stable in oil leakage protection, stable in performance and high in practicality, protects the environment, has the function of protecting the transformer, and prolongs the service life of the transformer.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a protection device for a transformer, in particular to a protection device with high sealing performance for preventing leakage and heat dissipation of an oil-immersed transformer. Background technique [0002] With the development of the electric power industry, transformers are also constantly developing. In order to reduce manufacturing costs, oil-immersed transformers are generally used, and the transformer mailbox is filled with transformer oil. The exchange of moisture into the oil will accelerate the aging speed of the oil. Over time, the performance of the transformer oil will be reduced, and the entry of air will oxidize the transformer iron core and copper core metal, causing acidic substances to appear in the oil, and the oil will Oil stains will also be produced after oxidation, resulting in poor heat transfer and temperature rise of the soli...

[0002] With the development of the electric power industry, transformers are also constantly developing. In order to reduce manufacturing costs, oil-immersed transformers are generally used, and the transformer mailbox is filled with transformer oil. The exchange of moisture into the oil will accelerate the aging speed of the oil. Over time, the performance of the transformer oil will be reduced, and the entry of air will oxidize the transformer iron core and copper core metal, causing acidic substances to appear in the oil, and the oil will Oil pollution will also be produced after oxidation, resulting in poor heat transfer and temperature rise of the solid insulating layer

It seriously threatens the operation cycle of the transformer, and the transformer is prone to transformer oil leakage accidents under the influence of oxidation and transportation for a long time, which will cause a section of the line, affect the normal power supply, and even cause the transformer to be burned or endanger the environment. Fire accidents, causing irreparable economic losses
