The drawer type switch cabinet is a closed shell made of steel plate, and the electrical components of the incoming and outgoing circuit are installed in the withdrawable drawer to form a functional unit that can complete a certain type of power supply task. The functional unit is separated from the bus or cable by a grounded metal plate or a functional plate made of plastic to form three areas of bus, functional unit and cable. Isolation measures are also taken between each functional unit.

GCS型低压开关柜一般都设有清晰的3段位置，GCS型抽屉式开关柜有个较大的缺点，其结构制作，尤其是装配比较麻烦，大多采用螺栓连接，抽屉分为1/2单元、1单元、1.5单元、2单元、3单元五个系列，PC柜多可做3个，MCC柜多可装22个抽屉回路，主柜安装模数孔E=20mm和100mm，抽屉层高160mm，母线采用背后平置式，电缆室上下均有出线通道，面板具有分、合、试验、抽出位置的明显标志。

GCS type low-voltage switchgear is generally equipped with clear 3-section positions. GCS type drawer type switchgear has a major disadvantage. Its structure fabrication, especially assembly, is troublesome, and most of them are connected by bolts. The drawers are divided into five series: 1 / 2 unit, 1 unit, 1.5 unit, 2 unit and 3 unit. There can be at most 3 PC cabinets and 22 drawer circuits in MCC cabinet, The installation module hole of the main cabinet is e = 20mm and 100mm, the drawer layer height is 160mm, the bus is flat at the back, there are outlet channels at the top and bottom of the cable room, and the panel has obvious signs of opening, closing, test and extraction positions.

GCK型低压开关柜具有分断能力高、动热稳定性好、结构合理，GCK型抽屉式开关柜电气方案灵活、系列性、通用性强、各种方案单元任意组合、一台柜体。

GCK type low-voltage switchgear has high breaking capacity, good dynamic and thermal stability, advanced and reasonable structure. GCK type drawer type switchgear has flexible electrical scheme, strong seriality and universality, arbitrary combination of various scheme units and one cabinet.

所容纳的回路数较多、节省占地面积、防护等级高、可靠、维修方便等优点，抽屉分为1/2单元、1单元、2单元、3单元，多可装9个单元，柜体可装18个单元。抽屉具有合、分、试验、抽出位置，即能保证正常的工作，又可检修抽屉内的元件，从抽屉的推进方式上又基本上分单拨插式，双拨插式，摇进式。

The drawer has the advantages of large number of circuits, saving floor area, high protection level, safety and reliability, convenient maintenance, etc. the drawer is divided into 1 / 2 unit, 1 unit, 2 unit and 3 unit, up to 9 units can be installed, and the cabinet can be installed with 18 units. The drawer has closing, opening, testing and extraction positions, which can not only ensure normal operation, but also safely overhaul the components in the drawer. From the propulsion mode of the drawer, it is basically divided into single pull-in type, double pull-in type and swing in type.

有的抽屉单元大多数没有清晰的3断位置，只能实现基本的连锁，大多数没有实验位置，主架安装模数孔E=25mm，GCK型抽屉式开关柜抽屉柜高度为1800mm，每一功能单元均占一独立隔室，抽屉层高200mm，但随着电气工业的发展，断路器体积越来越小，亦可水平安装。

Most of some drawer units have no clear 3-off position and can only realize basic interlocking. Most of them have no experimental position. The installation module hole of the main frame is e = 25mm. The height of the drawer cabinet of GCK drawer switch cabinet is 1800mm. Each functional unit occupies an independent compartment and the drawer floor height is 200mm. However, with the development of the electrical industry, the volume of the circuit breaker is getting smaller and smaller and can also be installed horizontally.

MNS型低压开关柜结构为组合式，MNS型抽屉式开关柜它分为标准型和非标型，框架的全部结构件经过镀锌或采用镀锌板、进口敷铝锌板折成型材。

The structure of MNS low-voltage switchgear is combined, and MNS drawer switchgear is divided into standard type and non-standard type. All structural parts of the frame are galvanized or folded into profiles by galvanized plate and imported aluminum zinc coated plate.

模数孔E=25mm，通过各种联结件、自攻锁紧螺钉和8.8级六角螺栓联结，框架结构无需专用工具即能组装，柜内隔板采用分段式多功能隔离板，可使PC柜和MCC柜实现混装，抽屉层高200mm，可分为8E/4、8E/2、8E、16E、24E，MCC柜的有效高度为72E，多可装36个出线回路。

Modular hole e = 25mm, which is connected through various connectors, self tapping locking screws and grade 8.8 hexagon bolts. The frame structure can be assembled without special tools. The partition plate in the cabinet adopts segmented multi-functional isolation plate, which can realize mixed loading of PC cabinet and MCC cabinet. The drawer layer height is 200mm, which can be divided into 8e / 4, 8e / 2, 8e, 16e and 24E. The effective height of MCC cabinet is 72e, and 36 outgoing circuits can be installed at most.
