結構特點及功能

Structural Characteristics and Functions

★柜體采用通用柜的形式，構架用8MF冷彎型鋼局部焊接組裝而成，構架零件及專用配套零件由型鋼定點生產廠配套供貨，以保證柜體的精度和質量；

★在柜體上下兩端均有不同數量的散熱槽孔，當柜內電器元件發熱后，熱量上升，通過上端槽孔排出，而冷風不斷地由下端槽孔補充進柜，使密封的柜體自下而上形成一個自然通風道，達到散熱的目的：

★柜門用轉軸式活動鉸鏈與構架相連，安裝、拆卸方便。門的折邊處均嵌有一根山型橡塑條，開門時門與構架之間的嵌條有一定的壓縮行程，能防止門與柜體直接碰撞，也提高了門的防護等級。

★柜體的頂蓋在需要時可拆除，便于現場主母線的裝配和調整，柜頂的四角裝有吊環，便于起吊和裝運。

The cabinet adopts common cabinet form. The framework is made through the local welding and assembly of 8MF cold bending profile steel. The frame parts and the special necessary parts are provided accordingly 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 heat dispersion hole slots. After the electrical components inside the cabinet heats, the heat in the cabinet is increased and discharged through the upper slots while the cooling air is constantly added to enter the cabinet through the bottom slots so that a natural ventilation duct of the sealed cabinet from bottom to upper is established for the purpose of heat dissipation.

The door of the cabinet is connected to the framework by using the revolving shaft moving hinge which is convenient for installation and dismantlement. A mountain-type rubber strip is inserted in the folding places of the door, and there is a certain compression stroke for the inserted strip between the door and the framework when the door opens, which can prevent the direct collision between the door and the cabinet and also improve the protection level of the door.

The top cover of the cabinet can be removed as required to facilitate to the assembly and adjustment of the main buses on site. The lifting rings are fixed in four corners of the top of the cabinet, convenient for lifting and transportation.
