山东MNS低压抽屉柜是一种使用高压配电上面的柜体，所以这样的柜体在安装的时候需要注意一些事项。

Shandong MNS low-voltage drawer cabinet is a cabinet that uses high-voltage distribution, so there are some precautions to be taken when installing such cabinets.

1.山东MNS低压抽屉柜正常生产过程中的标高或者垂直上面是允许有偏差的，一般是由于测量定位或者地面不平造成的，这个时候需要及时进行修改。

During the normal production process of Shandong MNS low-voltage drawer cabinets, deviations in elevation or vertical orientation are allowed, which are generally caused by measurement positioning or uneven ground. At this time, timely modifications are needed.

2.MNS柜体配电箱的铁架上面不正，在安装的铁架之前没有进行调整好，或者安装的固定位置偏移造成的。这一块一定要固定好。

2. The iron frame of the MNS cabinet distribution box is not aligned, and it was not adjusted before installation, or the fixed position of the installation is offset. This piece must be securely fastened.

3.MNS柜体配电箱盘面电具以及仪表不牢固这些都是很重要的。

3. It is important that the electrical appliances and instruments on the MNS cabinet distribution box panel are not securely fastened.

4.MNS柜体接地导线截面上面不够或者保护地线截面不够的话，是会出故障的，这些情况一般是公用建筑工程或者民用住宅上面是一定不要使用的。

If the cross-section of the grounding wire of the MNS cabinet is not enough or the cross-section of the protective ground wire is not enough, it will cause a fault. These situations are generally not suitable for public building projects or residential buildings.

5.MNS柜体的盘后配线如果排列不整齐的话，需要按照支路绑扎，然后固定在盘内。

If the wiring behind the MNS cabinet is not arranged neatly, it needs to be tied according to the branch and then fixed inside the panel.

山东MNS低压抽屉柜结构特点：

Structural characteristics of Shandong MNS low-voltage drawer cabinet:

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;

1. The MNS type low-voltage switchgear frame is a modular structure, with the basic skeleton assembled from C-shaped steel. All structural components of the cabinet frame have been galvanized and secured with self tapping locking screws or 8. The basic cabinet frame is firmly connected with 8-level hexagonal bolts, and the complete switchgear is assembled with components such as doors, partitions, installation brackets, and busbar functional units corresponding to the scheme changes. The internal dimensions, component dimensions, and compartment dimensions of the switchgear are all changed according to modularization (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 combination low-voltage switchgear is divided into three compartments, namely the horizontal busbar compartment (at the back 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 busbars and other circuits due to faults in switch components;

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;

3. The structural design of MNS type low-voltage switchgear can meet the requirements of various incoming and outgoing line schemes: upper inlet and upper outlet, upper inlet and lower outlet, lower inlet and upper outlet, lower inlet and lower outlet;

4、设计紧凑:以较小的空间容纳较多的功能单元;

4. Compact design: accommodates more 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 pull-out 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 strength plastic functional boards, 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 mechanism of drawers of various sizes meets the standard requirements, 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 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 the protective and 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. Universalization, high degree of standardization, and easy assembly. Having reliable quality assurance;
