主要特点 Main feature

◇ GCK1，GCJ1 为拼装式组合结构，基本骨架采用专用型材，拼装而成；

◇ 柜体骨架，零件尺寸以及开孔尺寸按基本模数E=25mm 变化；

◇ 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；

◇ 由于框架的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；

◇ 零部件通用性强，适用性好，标准化程度高；

◇ 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。

◇ GCK1 and GCJ1 are assembled composite structures, and the basic skeleton is assembled by special profiles；

◇ The cabinet frame, part size and opening size change according to the basic modulus E=25mm；

◇ In MCC scheme, the cabinet is divided into five areas (rooms): horizontal bus area, vertical bus area, functional unit area, cable room and neutral grounding bus area. The districts are isolated from each other to ensure the normal operation of the line and effectively prevent the fault from expanding；

◇ Because all the structures of the frame are fastened and connected by screws, the welding deformation and stress are avoided and the accuracy is improved；

◇ Parts have strong universality, good applicability and high standardization.

◇ The extraction and insertion of functional units (drawers) are lever operation, and the operation with rolling bearings is light and reliable.
