Box body structure of dry transformer

The invention relates to a box body structure of a dry transformer. In the box body structure, support frameworks which are shared by a left side surface and a top end surface, the left side surface and a bottom end surface, a right side surface and a top end surface and the right side surface and the bottom end surface all employ telescopic support frameworks, and plates forming the left side surface, the right side surface, the top end surface and the bottom end surface of the box body structures stretches with the stretching of the telescopic support frameworks. Since the support frameworks with telescopic and adjustable lengths are arranged, the box body structure is convenient to transmit, load and unload; and the box body structure is convenient to splice, is high in visuality and good in ventilation and heat dissipation. 本发明干式变压器箱体结构，其箱体结构的左侧面与顶端面、左侧面与底端面、右侧面与顶端面、右侧面与底端面所共用的支撑框架均采用可伸缩支撑框架，构成箱体结构的左侧面、右侧面、顶端面及底端面的板材随所述可伸缩支撑框架的伸缩而伸缩。本发明由于设有长度可伸缩调节的支撑框架，便于运输装卸；箱体结构拼接方便，可视性强，透气散热性好。
