1、架為組合式結構，基本架由C型鋼組裝而成，架體所有結構件均鍍鋅，用自攻鎖緊螺釘或8.8級六角螺栓與基本架牢固連接。開關柜的內部尺寸、元器件的尺寸、隔室的尺寸都是按模數。

1. The frame is a combination structure, and the basic frame is assembled from C-shaped steel. All structural components of the frame are galvanized and firmly connected to the basic frame with self tapping locking screws or 8.8 grade hexagonal bolts. The internal dimensions of the switchgear, the dimensions of the components, and the dimensions of the compartments are all based on modulus.

2、每個機柜分為三個房間，即水平母線室、抽屜室、電纜室。室之間用鋼板或高強度阻燃塑料功能板隔開，上下抽屜用帶通風孔的金屬板隔開，有效地防止了因故障引起的開關元件電弧或母線與其它線路之間的短路而造成的事故原因。

2. Each cabinet is divided into three rooms, namely the horizontal busbar room, drawer room, and cable room. The rooms are separated by steel plates or high-strength flame-retardant plastic functional boards, and the upper and lower drawers are separated by metal plates with ventilation holes, effectively preventing accidents caused by arcing of switch components or short circuits between busbars and other circuits due to faults.

3、結構設計符合進出線方案的要求。上進上出，上進下出，下進上出，下進下出。

3. The structural design meets the requirements of the incoming and outgoing line scheme. Upward and upward, upward and downward, downward and upward, downward and downward.

4、緊湊型設計：在更小的空間內容納更多的功能單元。

4. Compact design: accommodates more functional units in a smaller space.

5、結構件通用性強，組裝靈敏，結構和抽出式單元可任意組合，滿足系統設計的需要。

5. The structural components have strong universality, sensitive assembly, and can be freely combined with pull-out units to meet the needs of system design.

6、母線采用高強度阻燃、高介電強度塑料功能板保護，具有抗故障電弧性能，運行維護防護可靠。

6. The busbar is protected by high-strength flame-retardant and high dielectric strength plastic functional boards, which have anti fault arc performance and reliable operation and maintenance protection.

7、標準模塊設計：可由標準單元組成保護、操作、轉換、控制、調整、測量、指示等，可根據要求任意組裝。

7. Standard module design: It can be composed of standard units for protection, operation, conversion, control, adjustment, measurement, indication, etc., and can be assembled according to requirements.
