摘要

12 kV充气式环网柜在中国供配电领域应用广泛，生产厂家众多，其气箱一般由不锈钢钣焊接而成。通过三维建模和仿真计算来分析气箱上加强筋的布置方式对气箱变形的影响，发现对于近似于矩形的气箱侧板，加强筋沿着平行于短边的方向依次布置优于加强筋横纵或沿着平行于长边的方向布置，得出通过合理布局加强筋的位置可以获得变形较小且较经济的气箱。分别对使用3、2.5、2 mm板厚焊接而成的气箱进行仿真计算，得出使用2.5 mm厚不锈钢钣金焊接而成的气箱具有相对较好的设计经济性。

Abstract

12 kV gas filling ring main unit is widely used in the power supply and distribution field in China and the gas compartment in many manufacturers is generally soldered from stainless steel sheet. The influence of the layout of stiffeners on the deformation of the gas compatment is analyzed through 3D modeling and simulation calculation

finding that for the side plate of the approximately rectangular gas comprtment the layout of stiffeners along the direction parallel to the short side is better than that in transverse and longitudinal directiona or along the direction parallel to the long side. It is concluded that the gas compartment with smaller deformation and economic performance can be obtained by reasonable layout of the stiffeners. The gas compartments soldered from thickness of 3 mm

2.5 mm and 2 mm plate are simulated and calculated respectively. It is concluded that the gas compartmet soldered from the thickness of 2.5 mm stainless steel sheet exhibits relatively favorable economic efficiency in design.
