结构特点及功能
Structural Characteristics and Functions

★柜体采用通用柜的形式,构架用8MF冷弯型钢局部焊接组装而成,构架零件及专用配套零件由型钢定点生产厂配套供货,以保证柜体的精度和质量;

★在柜体上下两端均有不同数量的散热槽孔,当柜内电器元件发热后,热量上升,通过上端槽孔排出,而冷风不?#31995;?#30001;下端槽孔补充进柜,使密封的柜体自下而且上形成一个自然通风道,达到散热的目的;

★柜门用转轴式活动铰链与构架相连,安装、拆卸方便。门的折边处均嵌有一根山型橡塑条,开门时门与构架之间的嵌条有一定的压缩行程,能?#20048;?#38376;与柜体直接碰撞,也提高了门的防护等级。

★柜体的顶盖在需要时可拆除, 便于现场所主母线的装配和调整,柜顶的四角装有吊环,用于起吊和装运。


The cabinet is of common form. The framework is composed of 8MF cold bending profile steel welded and assembled. The frame parts and the special necessary parts are provided by the specially appointed manufacturers so as to ensure the precision and quality of the cabinet;

At the upper and lower ends of the cabinet there are different numbers of cooling slots. When the electrical components inside of the cabinet are scattering heat,  the heat in the cabinet is increased and discharged through the top cooling slots while the cooling air is entering constantly the cabinet through the bottom cooling slots, forming from bottom to top a natural ventilation duct to scatter the heat;

The door of the cabinet is connected with the axis hinge to the framework and the disassembling is rather convenient. A rubber insertion strip is fixed at the edge of the door for avoiding direct collision of the door with the cabinet, increasing the protection level of the door.

The cap of the cabinet can be removed, if necessary, for the convenience of assembling and adjustments of the main buses. The lifting rings are fixed at four corners of the top of the cabinet for lifting snd transportation.
