Embodiment 1

[0035] see Figure 1-3 and Figure 9 , an oil-immersed distribution transformer for easy oil filling, comprising a transformer main body 1, an oil conservator main body 3 is arranged on the upper side of the transformer main body 1, a pair of brackets 2 are fixedly connected between the transformer main body 1 and the oil conservator main body 3, the transformer main body 1 and the main body of the oil conservator 3 are connected with a connecting pipe 4, and the two ends of the connecting pipe 4 respectively pass through the main body of the transformer 1 and the main body of the oil conservator 3 and communicate with the main body of the transformer 1 and the main body of the oil conservator 3. The inner wall of the main body of the oil conservator 3 is fixedly connected with Partition plate 7, the partition plate 7 divides the inside of the main body of the oil conservator 3 into two parts: the oil injection chamber and the transition chamber. The upper end of the main body...

Abstract

The invention discloses an oil-immersed distribution transformer convenient for oil injection, and belongs to the field of oil-immersed transformers. According to the scheme of the oil-immersed distribution transformer convenient for oil injection, in the oil injection process, transformer oil enters a transition chamber through an exchange hole and an elastic fiber cluster, the communicated compartments formed by a straight part and a three-dimensional spiral part in the elastic fiber cluster can effectively buffer the transformer oil, the situation that the flowing speed of the transformer oil is too high is avoided, bubbles are not prone to being formed, meanwhile, the bubbles existing in the transformer can be cut and broken through the straight part, the three-dimensional spiral part and a prefabricated groove, and the bubble removing effect is achieved. In the process of replacing the transformer oil of the oil-immersed transformer, bubbles are not prone to being generated, normal work of the oil-immersed transformer is not prone to being affected, damage caused by overheating of the oil-immersed transformer is not prone to being caused, breakdown of the transformer oil is not prone to being caused, and normal use of the oil-immersed transformer is not prone to being affected.

Description

technical field [0001] The invention relates to the field of oil-immersed transformers, in particular to an oil-immersed distribution transformer that is convenient for oil filling. Background technique [0002] At the end of the 19th century, transformers began to use transformer oil as an insulation and cooling medium, and oil-immersed transformers appeared. In addition to the abundant natural storage capacity and low price of transformer oil, transformer oil has the following characteristics, and it is used in conjunction with fiber materials. Good insulation performance, It can reduce insulation distance and reduce cost; transformer oil has low viscosity and good heat transfer performance, which can well protect iron core and winding from the influence of moisture in the air, protect insulating paper and insulating cardboard from oxygen, and reduce The aging of insulating materials prolongs the life of transformers; except for some special-purpose small and medium-capaci...
