主结构 / Main structure

主构架采用 8MF 型开口型钢，型钢的二侧面分别有模数为 20mm 和 100mm 和 Φ9.2mm 的安装孔，内部安装灵活方便；
主构架装配形式设计为两种，全组装式结构和部份 ( 侧框和横梁 ) 焊接式结构，供用户选择；
装置的各功能室相互隔离，其隔室分为功能单元室、母线室和电缆室。各室的作用相对独立；
The main frame adopts 8MF type open section steel. The two sides of the section steel have mounting holes of 20mm and 100mm and Φ9.2mm respectively. The
internal installation is flexible and convenient;
The main frame assembly form is designed as two types, fully assembled structure and part (side frame and beam) welded structure for users to choose;
The functional rooms of the device are isolated from each other, and the compartments are divided into functional unit rooms, busbar rooms and cable rooms. The
role of each chamber is relatively independent;
