一:结构特点 /Structure characteristics
 

1.柜体采用拼装式结构,主构架用以 20mm 模数的 FA 型材装配而成。

2.开关柜各功能室严格分开,其隔室主要分为功能单元室、母线室、电缆室,各单元的功能作用相对独立。在母线室可设置供安放柜间连接线和共用电源室的控制回路电缆槽。

3.一个抽屉为一个独立功能单元。MCC柜的抽屉有三种标准尺寸,都以8E(200mm)高度为基准,三种抽屉单元可作单一组装,也可混合组装。单一组装时最多可容纳9个抽屉单元。

4.抽屉单元装有可靠的机械联锁装置,只有在分断开关的状态下才能被打开,同时抽屉具有明显的合闸、试验、分断位置显示。机械联锁的操作手柄定位后可加挂最多 3 把挂锁。

 

1.Spliced cubicle body, the main structural frame is made up of ICB formed steel with modulus 20mm

2.All functional compartment are strictly separated each other, they are mainly divided into functional unit,bus nuit and cable unit, the unit's function is relatively independent, There is cable wireway for placing intercubicle connecting wires and a contrding circuit of shared power line in the bus room.

3.Each drawer is a independent functional unit. There are three standard dimensions for MCC cubicle's drawers, 8E( 200mm ) is their height base, three-type drawers of different heights can assembled in one, the max drawer number in a cubicle is nine.

4.There is mechanical interlock for the drawer units, they can be opened only if the switch is at break-off state. The drawers have apparent position indication for close~ test and off. Three padlocks may be locked on the operating handle of the mechanical interlock, if necessary.
