　　二、MNS 低壓抽屜柜的特點與應(yīng)用

　　2、 Characteristics and Applications of MNS Low Voltage Drawer Cabinet

　　結(jié)構(gòu)與連接方式：MNS 型低壓抽屜式開關(guān)柜通常包含多個抽屜層，由塵板分隔。每個抽屜層有兩個隔離的抽屜式功能單元，每個功能單元包括抽屜體、導(dǎo)軌和推進機構(gòu)。

　　Structure and connection method: MNS type low-voltage drawer type switchgear usually includes multiple drawer layers separated by dust plates. Each drawer layer has two isolated drawer style functional units, each of which includes a drawer body, guide rails, and push mechanism.

　　導(dǎo)軌固定在塵板上，抽屜體與導(dǎo)軌配合。推進機構(gòu)位于抽屜體下部，包括帶有弧形開口導(dǎo)槽的轉(zhuǎn)盤、上部帶有夾緊帽的樞軸、推桿、拉桿和安裝在塵板上的導(dǎo)向件。

　　The guide rail is fixed on the dust board, and the drawer body is matched with the guide rail. The propulsion mechanism is located at the lower part of the drawer body, including a turntable with an arc-shaped opening guide groove, a pivot with a clamping cap on the upper part, a push rod, a pull rod, and a guide installed on the dust plate.

　　獨立的單元電路：在這種低壓開關(guān)柜中，采用了更多的抽屜式功能單元，但體積并未增加。單元電路相互獨立，互不干擾，每個功能單元電路的斷開位置、試驗位置和接通位置之間的切換可以獨立完成。

　　Independent unit circuit: In this low-voltage switchgear, more drawer style functional units are used, but the volume has not increased. The unit circuits are independent of each other and do not interfere with each other. The switching between the disconnection position, test position, and connection position of each functional unit circuit can be independently completed.
