1、架为组合式结构，基本架由C型钢组装而成，架体所有结构件均镀锌，用自攻锁紧螺钉或8.8级六角螺栓与基本架牢固连接。开关柜的内部尺寸、元器件的尺寸、隔室的尺寸都是按模数。

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、每个机柜分为三个房间，即水平母线室、抽屉室、电缆室。室之间用钢板或高强度阻燃塑料功能板隔开，上下抽屉用带通风孔的金属板隔开，有效地防止了因故障引起的开关元件电弧或母线与其它线路之间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、结构设计符合进出线方案的要求。上进上出，上进下出，下进上出，下进下出。

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、紧凑型设计：在更小的空间内容纳更多的功能单元。

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

5、结构件通用性强，组装灵敏，结构和抽出式单元可任意组合，满足系统设计的需要。

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、母线采用高强度阻燃、高介电强度塑料功能板保护，具有抗故障电弧性能，运行维护防护可靠。

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、标准模块设计：可由标准单元组成保护、操作、转换、控制、调整、测量、指示等，可根据要求任意组装。

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.
