An oil-immersed transformer for electric power

Abstract

The invention discloses an electric power oil immersed transformer. The oil immersed transformer structurally comprises a transformer main body, a machine base, a heat dissipation assembly, a high-low-pressure sleeve, an oil storage tank and an exhaust siphon double protection device, wherein the transformer main body is of a rectangular structure; and the machine base is arranged below the transformer main body and is of an integrally formed structure. According to the oil immersed transformer, the exhaust siphon double protection device is arranged; flow distribution oil storage can be realized through a spherical network pipe; heating is performed by relatively large-area contact between a heating device and stored oil; heat of the heat dissipation assembly of the transformer is used for heating the stored oil, so that the utilization rate of energy is increased; and then the siphon benefit is utilized for ensuring that the oil added into the transformer is free of gas again, ensuring that no bubbles exist in the transformer, preventing the phenomenon of bubble discharge, and reducing the electric loss.

Description

technical field [0001] The invention relates to the field of transformers, more precisely, an oil-immersed transformer for electric power. Background technique [0002] Oil-immersed transformer is a new type of high-performance transformer with more reasonable structure and better performance. The three-dimensional wound iron core has three-dimensional arrangement of equilateral triangles, so there is no air gap in the magnetic circuit and the winding is more compact. , the three magnetic circuits have the same length and are the shortest, and the cross-sectional area of ​​the core column is closer to a circle, so the performance is further improved, the loss is reduced, the noise is reduced, the three items are balanced, and the third harmonic component is reduced, but the existing The technical oil-immersed transformer for power still has the following defects: [0003] In order to replenish the consumed oil in the transformer in time, the oil-immersed transformers are eq...

Problems solved by technology

[0003] In order to replenish the consumed oil in the transformer in time, the oil-immersed transformers are equipped with an oil storage tank, which can be added when the oil in the oil storage tank is almost exhausted. However, when adding oil to the oil storage tank, due to the oil filling If the oil is directly added into the transformer, it will cause air bubble discharge, which will cause power consumption and be dangerous at the same time.
