Embodiment 1

[0031] On the top and bottom of the main body 1, there are oil collecting pipe inlet and outlet 2 respectively, and there is an oil passage 3 inside the main body. The middle part of the oil passage is a high point, and the inclination angle to both sides θ for 13 o ;The width of the oil passage gradually increases from the middle to both sides according to the arithmetic sequence, and the tolerance d =3mm.

Embodiment 2

[0033] On the top and bottom of the main body 1, there are oil collecting pipe inlet and outlet 2 respectively, and there is an oil passage 3 inside the main body. The middle part of the oil passage is a high point, and the inclination angle to both sides θ for 13 o ;The width of the oil passage gradually increases from the middle to both sides according to the arithmetic sequence, and the tolerance d =6.5mm.

Abstract

The invention relates to a plate radiator unit box for a double-sloping-shoulder transformer, which belongs to the field of transformer radiators. An oil collecting pipe inlet and an oil collecting pipe outlet are formed above and below a main body respectively; an oil channel is formed inside the main body; a high point is formed on the middle part of the oil channel; and the inclination angles theta of the oil channel inclining towards both sides are 13-20 degrees. The plate radiator unit box has the advantages: the structure is novel; and in the refitting process of a plate radiator of an ordinary transformer, a shoulder is cut on a horizontal oil flow channel on the middle upper part of a sheet fan at a certain angle, an upper oil flow channel is widened gradually, pressure distribution in the sheet fan tends to be consistent, and the flow field distribution inside the sheet fan tends to be uniform, so that heat of transformer oil is exchanged completely in a single sheet fan. Theoretical analysis and simulation testing analysis are performed on the flowing and heat transferring properties of transformer cooling oil before and after refitting respectively, so that an optimal angle theta is obtained.

Description

technical field [0001] The invention belongs to the field of transformer radiators. Background technique [0002] Domestically used transformer chip radiators are mainly produced according to the standard requirements of "JB5347-1999 Transformer Chip Radiators". The shape of a single chip is as follows: figure 1 As shown, the leaf height and leaf width must meet the standard requirements. Hereinafter referred to as the ordinary type transformer chip radiator unit box. [0003] With the advancement of science and technology and the rapid development of the national economy, people's demand for energy in life and production is gradually increasing, especially for electric energy. Therefore, the power system is gradually developing in the direction of large capacity, large power grid, and UHV. Transformer is one of the important electrical equipment in the power system, which can convert high voltage and large current into another (or several) different voltages and currents ...
