MNS型低壓抽出式成套開關設備(以下簡稱開關柜)為適應電力工業發展的需求，能廣泛用于發電廠、變電站、工礦企業、大樓賓館、市政建設等各種低壓配電系統。MNS抽屜柜結構特點表現在12個方面：

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型低壓開關柜框架為組合式結構，基本骨架由C型鋼材組裝而成。柜架的全部結構件經過鍍鋅處理，通過自攻鎖緊螺釘或8.8級六角螺栓堅固連接成基本柜架，加上對應于方案變化的門、隔板、安裝支架以及母線功能單元等部件組裝成完整的開關柜。開關柜內部尺寸、零部件尺寸、隔室尺寸均按照模數化(E=25mm)變化。

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型組合式低壓開關柜的每一個柜體分隔為三個室，即水平母線室(在柜后部)，抽屜小室(在柜前部)，電纜室(在柜下部或柜前右邊)。室與室之間用鋼板或高強度阻燃塑料功能板相互隔開，上下層抽屜之間有帶通風孔的金屬板隔離，以有效防止開關元件因故障引起的飛弧或母線與其它線路短路造成的事故。

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型低壓開關柜的結構設計可滿足各種進出線方案要求：上進上出、上進下出、下進上出、下進下出。

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.設計緊湊：以較小的空間容納較多的功能單元。

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

5.結構件通用性強、組裝靈活，以E=25mm為模數，結構及抽出式單元可以任意組合，以滿足系統設計的需要。

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.母線用高強度阻燃型、高絕緣強度的塑料功能板保護，具有抗故障電弧性能，使運行維修可靠。

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.各種大小抽屜的機械聯鎖機構符合標準規定，有連接、試驗、分離三個明顯的位置，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.采用標準模塊設計:分別可組成保護、操作、轉換、控制、調節、測定、指示等標準單元，可以根據要求任意組裝。

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.采用高強度阻燃型工程塑料，有效加強了防護性能。

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

10.通用化、標準化程度高，裝配方便。具有可靠的質量保證。

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

11.柜體可按工作環境的不同要求選用相誚的防護等級。

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

12.設備保護連續性和可靠性。

12. Equipment protection continuity and reliability.
