MNS型低压抽出式成套开关设备(以下简称开关柜)为适应电力工业发展的需求，能广泛用于发电厂、变电站、工矿企业、大楼宾馆、市政建设等各种低压配电系统。MNS抽屉柜结构特点表现在12个方面：

MNS low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is widely used in various low-voltage distribution systems such as power plants, substations, industrial and mining enterprises, buildings, hotels, municipal construction, etc. to meet the needs of the development of the power industry. The structural characteristics of MNS drawer cabinets are manifested in 12 aspects:

1.MNS型低压开关柜框架为组合式结构，基本骨架由C型钢材组装而成。柜架的全部结构件经过镀锌处理，通过自攻锁紧螺钉或8.8级六角螺栓坚固连接成基本柜架，加上对应于方案变化的门、隔板、安装支架以及母线功能单元等部件组装成完整的开关柜。开关柜内部尺寸、零部件尺寸、隔室尺寸均按照模数化(E=25mm)变化。

The MNS type low-voltage switchgear frame is a modular structure, and the basic framework is assembled from C-type steel. All structural components of the cabinet frame are galvanized and firmly connected to the basic cabinet frame through self tapping locking screws or 8.8 grade hexagonal bolts. In addition, corresponding components such as doors, partitions, installation brackets, and busbar functional units are assembled into a complete switchgear. The internal dimensions, component dimensions, and compartment dimensions of the switchgear vary according to modulus (E=25mm).

2.MNS型组合式低压开关柜的每一个柜体分隔为三个室，即水平母线室(在柜后部)，抽屉小室(在柜前部)，电缆室(在柜下部或柜前右边)。室与室之间用钢板或高强度阻燃塑料功能板相互隔开，上下层抽屉之间有带通风孔的金属板隔离，以有效防止开关元件因故障引起的飞弧或母线与其它线路短路造成的事故。

2. Each cabinet of the MNS type combined low-voltage switchgear is divided into three compartments, namely the horizontal busbar compartment (at the rear of the cabinet), the drawer compartment (at the front of the cabinet), and the cable compartment (at the bottom or right side of the cabinet). The rooms are separated from each other by steel plates or high-strength flame-retardant plastic functional boards, and there are metal plates with ventilation holes between the upper and lower drawers to effectively prevent accidents caused by arcing or short circuits between the switch components and other lines due to faults.

3.MNS型低压开关柜的结构设计可满足各种进出线方案要求：上进上出、上进下出、下进上出、下进下出。

The structural design of the MNS low-voltage switchgear can meet the requirements of various inlet and outlet schemes: upper in and upper out, upper in and lower out, lower in and upper out, and lower in and lower out.

4.设计紧凑：以较小的空间容纳较多的功能单元。

4. Compact design: accommodates a large number of functional units in a smaller space.

5.结构件通用性强、组装灵活，以E=25mm为模数，结构及抽出式单元可以任意组合，以满足系统设计的需要。

5. The structural components have strong universality and flexible assembly, with E=25mm as the modulus. The structure and withdrawable units can be combined arbitrarily to meet the needs of system design.

6.母线用高强度阻燃型、高绝缘强度的塑料功能板保护，具有抗故障电弧性能，使运行维修可靠。

6. The busbar is protected by high-strength flame-retardant and high insulation plastic functional plates, which have anti fault arc performance and ensure safe and reliable operation and maintenance.

7.各种大小抽屉的机械联锁机构符合标准规定，有连接、试验、分离三个明显的位置，可靠。

7. The mechanical interlocking mechanisms of various sizes of drawers comply with standard regulations, with three obvious positions for connection, testing, and separation, ensuring safety and reliability.

8.采用标准模块设计:分别可组成保护、操作、转换、控制、调节、测定、指示等标准单元，可以根据要求任意组装。

8. Adopting standard module design: it can form standard units for protection, operation, conversion, control, adjustment, measurement, indication, etc., and can be assembled arbitrarily according to requirements.

9.采用高强度阻燃型工程塑料，有效加强了防护性能。

9. The use of high-strength flame-retardant engineering plastics effectively enhances protective safety performance.

10.通用化、标准化程度高，装配方便。具有可靠的质量保证。

10. High degree of generalization and standardization, convenient assembly. With reliable quality assurance.

11.柜体可按工作环境的不同要求选用相诮的防护等级。

11. The cabinet body can be selected with corresponding protection levels according to different requirements of the working environment.

12.设备保护连续性和可靠性。

12. Equipment protection continuity and reliability.
