Abstract

The invention relates to a plate radiator of a sloping-shoulder transformer, which belongs to the field of transformer radiators. Plate radiator unit boxes for a double-sloping-shoulder transformer are arranged in parallel; an upper oil collecting pipe and a lower oil collecting pipe are connected with the plate radiator unit boxes for the double-sloping-shoulder transformer respectively; an included angle beta between the upper oil collecting pipe and a horizontal plane is 10-20 degrees; and the structure of each plate radiator unit boxes for the double-sloping-shoulder transformer is that: a main body is provided with an upper oil collecting pipe oil inlet / outlet and a lower oil collecting pipe outlet; 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 has the advantages: the structure is novel; and after an optimized design is adopted for an ordinary transformer sheet fan, i.e., an integral sloping shoulder and double sloping shoulders on a single sheet fan are adopted, the heat exchange efficiency of the sheet fan of a transformer sheet can be increased remarkably.

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 1a with Figure 1b As shown, the leaf height and leaf width must meet the standard requirements. Hereinafter referred to as ordinary transformer sheet radiator. [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 w...
