GCK低压抽出式成套开关设备主要特点 Main feature

1. GCK1、GCJ1 为拼装式组合结构，基本骨架采用专用型材，拼装而成。

2. 柜体骨架，零件尺寸以及开孔尺寸按基本模数E=25mm 变化。

3. 在MCC 方案中，柜内部分成五个区域（室）：水平母线区、垂直母线区、功能单元区、电缆室、中性接地母线区。各区互相隔离，保证线路正常运行，有效防止故障扩大。

4. 由于框架的所有结构均以螺钉紧固连接而成，避免了焊接变形和应力，提高了精度。

5. 零部件通用性强，适用性好，标准化程度高。

6. 功能单元（抽屉）的抽出、插入为杠杆操作，加上配置滚动轴承操作轻便、可靠。

1. GCK1 and REGCJ1 are assemble type combined structure. The basic skeleton is assembled by adopting special bar steel.

2. Cabinet skeleton, component dimension and starter size change according to basic modulus E=25mm.

3. In MCC project, parts in cabinet are divided into five zones (compartment): horizontal bus bar zone, vertical bus bar zone, function unit zone, cable compartment, and neutral earthing bus bar zone. Each zone is separated mutually for circuit’s normal running and effectively preventing fault expansion.

4. As all structures of framework are connected and firmed by bolts, so it avoids the welding distortion and stress, and upgrades the precision.

5. Strong general performance, well applicability and high standardization degree for components.

6. Draw-out and insert of function unit (drawer) is lever operation, which is easy and reliable with rolling bearing.
