主要特點  Main Features

 1、開關(guān)柜分為四個部分：母線室、功能單元室、電纜室和二次控制線橫向接線區(qū)。基于常規(guī)安全體系要求，用于調(diào)試和維護的小室或間隔空間均安裝有各自獨立的門板。

2、MDmax ST的框架采用自承重框架結(jié)構(gòu)，由雙折邊的G型材組裝而成，骨架上以25mm為間隔排布模數(shù)孔，高低壓開關(guān)柜廠家柜架裝配便利而又異常堅固。整個框架由橫向和縱向螺栓精確聯(lián)接，框架結(jié)構(gòu)免維護。骨架、隔板、安裝板均采用敷鋁鋅板制成。

3、開關(guān)元件的安裝方式有固定式、抽屜式、可移式、插入式，可根據(jù)不同要求自由搭配。

4、抽屜式分為1/4單元抽屜、1/2 單元抽屜和全寬度抽屜(抽屜高度: 1U 1.5U 2U 3U, U=200mm ),同規(guī)格抽屜可*互換。

5、抽屜由固定部件和可移動部件(接插件)構(gòu)成。抽屜固定部件推入開關(guān)柜單元小室后，關(guān)閉單元小室組件門，插入搖桿，可將抽屜可移部件在隔離、實驗和連接三位置之間按序轉(zhuǎn)換。并由帶LED的指示窗口顯示接插件的位置狀態(tài)。

6、柜體防護等級為IP40。

1. Switchgear is divided into four parts: Bus compartment, functional unit compartment, cable compartment, and horizontal connection area of secondary control line. Based on the requirement of conventional security system, independent door panels are installed for compartments and interval spaces for debugging and maintenance.

2. Frame of MDmax ST is in self- bearing structure composed of double-folded G-materials. Modular holes with interval of 25mm are distributed on the frame to facilitate frame assembly and ensure soundness. The whole frame is precisely linked by horizontal and vertical bolts to free from maintenance. Frame, baffle plate and installation plate are all made of aluminum zinc plates.

3. Switch elements can be installed in fixed, drawer, movable and inserted modes, and can be matched freely as demands.

4. Drawers are divided into 1/4, 1/2 and overall-width drawer (height: 1U, 1.5U, 2U, 3U, U=200mm), and drawer of the same specification can be exchanged compley;

5. Drawer is composed of fixed parts and movable parts (connector assembly). After pushing fixed components of drawer into unit compartment of switchgear, one can close the door of unit compartment and insert rocker to convert of drawer's movable parts between positions of separation, test and connection. The indication window with LED could display the position of connector assembly.

6. Switchgear protection grade is IP40;
