Temperature Distribution By The Fluent Software In Oil-Immersed Transformer Using Heat Pipe

Transformer is an important equipment in power system, it is very significant to the power economical transmission, flexible distribution and safely use. The transformer in a power project in various fields are a wide range of applications. Social life on the dependence of electrical greatly improved, the quality of power supply equipment requirements more strict than in the past.But because of this transformer used chip radiator, make their own horizontal size, transport and maintenance are very inconvenient, and the chip lower radiator cooling efficiency, often because of transformer oil temperature rise too high, causing insulation transformer oil Performance declined, oil flow charged, or even an aging transformer coil fires, explosions and other accidents. Therefore improving the natural cycle of cooling oil transformer cooling structure, improving its cooling efficiency, both in saving energy, or to extend the life of transformers, reduce heat accident, will bring about tremendous social and economic benefits.This paper presents a highly efficient use of heat pipe in oil-immersed transformers, increased cooling efficiency and improve the thermal properties of transformer can be satisfactorily resolved in the pit traditional transformer and a special environment, difficult to rely on natural convection cooling question. Because of the heat pipe flow and heat transfer are very complex, internal heat exchanger is a vapor-liquid phase transformation of two-phase flow, vulnerable to the impact of external interference minimal, the situation is not easy to achieve stable state. Heat pipe heat in the application inside the transformer is still very little research derived, from the experimental to the theoretical analysis, numerical simulation, has yet to be in-depth study. This paper is the experimental study in the early adoption on the basis of numerical simulation and theoretical analysis of this issue was studied. With a view to practical application of heat pipe technology to provide theoretical support.By using Fluent software for heating power of 500 W and 1000 when the heat pipe in the oil-immersed transformers, as well as the heat transfer within different structures within the transformer conducted heat transfer simulation calculation, calculation results and experimental basically consistent with the work done by this paper for future the design and application of computing and provide a theoretical basis to avoid the blindness of the experiment and experience of not theoretical guidance accuracy.
