Oil-immersed transformer based on vegetable oil

Abstract

The invention discloses an oil-immersed transformer based on vegetable oil. The transformer comprises a transformer shell, an oil tank, a transformer body, a heat transfer pipe, cooling plates and exhaust fans. The oil tank is installed at the upper left corner of the transformer shell. The vegetable oil is contained in the oil tank, and the vegetable oil has the characteristics of oxidation resistance and high ignition point. The transformer main body comprises an iron core, a primary coil and a secondary coil, wherein the primary coil and the secondary coil are both wound on the iron core. The two cooling plates are respectively installed at the two sides of the transformer. One end of the heat transfer pipe is connected to the cooling plates, and the other end of the heat transfer pipeis close to the transformer body. The two exhaust fans are respectively located behind the two cooling plates. The oil-immersed transformer based on the vegetable oil is simple in structure, the vegetable oil is adopted as insulating oil and cooling liquid, and the heat generated in the working process of the transformer can be effectively dissipated. Meanwhile, the used vegetable oil is resistantto oxidation and high in ignition point, and the normal work of the transformer is guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of transformers, in particular to an oil-immersed transformer based on vegetable oil. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core. In electrical equipment and wireless circuits, it is often used for voltage rise and fall, impedance matching, and safety isolation. [0003] Insulating oil is an important liquid insulating medium, which is widely used in electrical equipment such as transformers. Due to its low cost, good insulation and cooling performance, mineral insulating oil is widely used in electrical equipment manufacturing. However, the biodegradability of mineral insulating oil is poor. Once a serious leak occurs, it will cause serious pollution to the surrounding soil, water sources and even public communities; and mineral insul...

Problems solved by technology

[0004] Traditional transformers use mineral oil as insulation and cooling fluid, but the biodegradability of mineral insulating oil is poor. Once a serious leakage occurs, it will cause serious pollution to the surrounding soil, water sources and even public communities. Mineral insulating oil has a low ignition point and high temperature resistance And fire performance is poor, not suitable for use in places with high fire safety requirements such as mines, mines, military facilities, high-rise buildings; at the same time, natural oil reserves are limited, and it is expected that there will be a serious oil shortage in the middle of this century
