主要特点 Main Features

1、开关柜分为四个部分：母线室、功能单元室、电缆室和二次控制线横向接线区。基于常规安全体系要求，用于调试和维护的小室或间隔空间均安装有各自独立的门板。

2、MDmax ST的框架采用自承重框架结构，由双折边的G型材组装而成，骨架上以25mm为间隔排布模数孔，高低压开关柜厂家柜架装配便利而又异常坚固。整个框架由横向和纵向螺栓精确联接，框架结构免维护。骨架、隔板、安装板均采用敷铝锌板制成。

3、开关元件的安装方式有固定式、抽屉式、可移式、插入式，可根据不同要求自由搭配。

4、抽屉式分为1/4单元抽屉、1/2 单元抽屉和全宽度抽屉(抽屉高度: 1U 1.5U 2U 3U, U=200mm ),同规格抽屉可互换。

5、抽屉由固定部件和可移动部件(接插件)构成。抽屉固定部件推入开关柜单元小室后，关闭单元小室组件门，插入摇杆，可将抽屉可移部件在隔离、实验和连接三位置之间按序转换。并由带LED的指示窗口显示接插件的位置状态。

6、柜体防护等级为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 completely;

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;
