油浸变压器主绝缘中隔板的结构设计

Design of Barriers in Major Insulation of Oil-filled Transformer

论述了油浸变压器主绝缘结构中的油—隔板结构设计。线圈间采用隔板将大油隙分隔为小油隙是基于变压器油的体积效应;线圈端部布置角环除分隔油隙外,还提高了沿面放电强度。

It is stated how to design the structure of oil and barriers for major insulation of oil-filled transformer. Based on volume effect of transformer oil, big gap is turned into small gap by barriers applied to winding. Discharge field intensity of surface is rising in addition to oil gap split up while angle coil installed tap of winding.
