Ecological Systems and Devices Annotation << Back STUDY OF THE PHENOMENON HEAT TRANSFER IN THE INDUSTRIAL POWER TRANSFORMERS GAS COOLING A.S. Khismatullin, A.G. Khismatullin, A.R. Kamalov This article is devoted to the intensifi cation of the process of heat exchange, which is that the heat removal from heating oil in the transformer is carried out at the expense of the circulation bubbling sulfur hexafl uoride, pumped by the compressor. After surfacing bubbles insulating gas passes through the fi lter, holding the oil particles trapped by rising bubbles and then passing cleaning and cooling system, the duty cycle repeats. The paper discusses the phenomenon of heat transfer initiated by the acoustic fi eld in the medium. It is shown that the values of the transfer coeffi cients increase even in the case of the plane wave propagation in the homogeneous medium. The resulting spectral representation allows us to construct an expression transtsilyation transfer coefficients due to vibrations of different wave packets. Studies show that by passing electric gas bubbles through the transformer oil is an increase of the effective thermal conductivity. Pre-lag method of intensifying the cooling system by increasing the coeffi cient of heat transfer oil can improve the effi ciency of cooling systems of power oil transformers. Based on these studies can be developed environmentally friendly industrial units with adjustable diffusion coeffi cients and thermal conductivity, as well as the optimal mode of operation of these units with variable-speed chemical reactions.
