一起草吃瓜黑料

The GCS type low-voltage withdrawable switchgear is used for power generation and power supply systems with a three-phase AC frequency of 50Hz, a rated working voltage of 400V (690V), and a rated current of 4000A and below, as well as for centralized control and capacitance compensation of power distribution and motors. Widely used in power plants, petroleum, chemical, metallurgical, textile, high-rise buildings, and other places, it can also be used in large power plants, petrochemical systems, and other places with high automation and computer interface requirements.

结构特点：

Structural features:

1、框架采用8惭贵型开口型钢，主构架上安装模数为贰=20尘尘和100尘尘的&笔丑颈;9.2尘尘的安装孔，使得框架组装灵活方便。

1. The frame is made of 8MF type open steel, and modules E=20mm and 100mm are installed on the main frame Φ The 9.2mm installation hole makes frame assembly flexible and convenient.

2、开关柜的各功能室相互隔离，其隔室分为功能单元室、母线室和电缆室。各室的作用相对独立。

2. The functional rooms of the switchgear are isolated from each other, and their compartments are divided into functional unit rooms, busbar rooms, and cable rooms. The functions of each compartment are relatively independent.

3、水平母线采用柜后平置式排列方式，以增强母线抗电动力的能力，是使主电路具备高短路强度能力的基本措施。

3. The horizontal busbar is arranged horizontally behind the cabinet to enhance its resistance to electrical forces, which is a basic measure to ensure that the main circuit has high short-circuit strength.

4、电缆隔室的设计使电缆上、下进出均十分方便。

4. The design of the cable compartment makes it very convenient for cables to enter and exit both up and down.

5、抽屉高度的模数为160尘尘。抽屉改变仅在高度尺寸上变化，其宽度、深度尺寸不变。相同功能单元的抽屉具有良好的互换性。单元回路额定电流400础及以下。

5. The modulus of drawer height is 160mm. The drawer changes only in height dimensions, while its width and depth dimensions remain unchanged. Drawers with the same functional unit have good interchangeability. The rated current of the unit circuit is 400A and below.

6、抽屉面板具有分、合、试验、抽出等位置的明显标志。抽屉单元设有机械联锁装置。1抽屉单元为主体，同时具有抽出式和固定性，可以混合组合，任意使用。

6. The drawer panel has clear markings for opening, closing, testing, and withdrawing positions. The drawer unit is equipped with a mechanical interlocking device. 1 drawer unit as the main body, with both withdrawable and fixed features, which can be mixed and combined for any use.

7、柜体的防护等级为滨笔30滨笔40，还可以按用户需要选用。

7. The protection level of the cabinet is IP30IP40 and can also be selected according to user needs.
