General
NKXGN16-12/24/35- series fixed type indoor AC metal clad switchgear (SF6 RMU Abbreviation). one of minimized switchgear with the character of excellence reliability and maintenance free ,is a new product self –developed by R&D of our group based on the years experience in R&D and fabrication on products and on the advance technology
The product is suitable for AC 3 to 12/24/35KV power distribution system with configuration either ring
or radiant.. Its all live part including LBS,CB, ES and primary busbar are sealed in the tank made of
stainless steel and the elbow –shape cable connectors and adopted for the incoming or out-going, that
leds it is suitable for use in the bad ambient condition and relatively restricted space ,just like in
pre-fabricated substation, underground substation, industrial and mining enterprises or in high humidity
and heavy pollution area.
The series of RMU is compliance with the following standards and its service life is mord than 20 years under normal ambient condition.

开关母线室 LBS-Busbar chamber
●不锈钢密封气箱（除熔断器外），构成了开关母线室。
The LBS-busbar chamber is formed by Stainless steel gas sealed tank besides fuses.
三相负荷开关作为一个整体部件调试完后装入气箱内，开关结构为旋转式三工位，兼备隔离和接地功能。开关静触头上装有金属栅栏，且呈曲线型，增强灭弧时去游离效果。
Three-phase LBS is fixed in gas sealed tank as a compiete component after assembly and adjustment. The structure of LBS is of rotary type three positions one ,it is with disconnection and isolation function.There are matel arc-barries on top of static contacts arrayed in curve to enhance the dis-extrication effect during are-extinguishing.
●为优化气箱内的电场分布，主母线设计为带R5圆角的矩形铜排，环网回路母线和变压器回路母线分别为Φ20mm和Φ10mm的铜棒，对可能引起尖端放电的部位，如母线连接及固定处，均装设了金属屏蔽罩，用以均匀电场，提高绝缘强度。
For optimize the electric field inside tank , the rectangle shape main busbars are designed to be with R5 fillet,the loop busbar of ring net and transformer adopt copper rods with diameter of Φ20mm and Φ10mm separately, the metal shield covers are used in somewhtere the point or marginal discharge may cause just like the connections and the fixed of busbar, for equalizing the electric field therefore rising up the insulation strength
操作机构室 Operating mechanism chamber
●操作机构室位于充气柜的上半部分，机构滚轴与开关操作盘紧配，并通过螺栓固定。
The operating mechanism chamber is located on the top half of cubicle, the rolling shaft of mechanism is matched tightly with switch operating plate and fixed by bolts.
●机构分单弹簧（进线机构）和双弹簧（出线机构）分别组成了环网回路和变压器回路开关，弹簧均为盘式弹簧，具有装配精度高、操作省力、寿命长、稳定性高的特点。
The operating mechanism which is of disk spring type with high assembly preesion and stability and with long service life and easy operation is divided into two types, the single spring using for ring net circuit (incomer unit) and double spring using for transformer circuit (outgoing unit).
熔断器室 Fuse chamber
●熔断器室（熔断器密封仓）位于柜体中部，置于充满SF6气体的气箱中。 熔断器密封仓由采用APG工艺浇注的环氧树脂绝缘筒及上导电极和下导电极（端盖）组成。前门上有熔断器动作指示器，方便观察和维护。用操作手柄拧开可方便更换熔断器。
Fuse chamber (fuse silo), consisting of epoxy resin insulation barrels casted by APG technology and upper and nether conductors (cover), is located in middle of cubicle and built in SF6 gas filled tank. There are melt indicators of fuse on the front door for easy checking and maintaining. The operating handle can be used for replacing the fuse body after unscrewing the covers.
电缆室 Cable chamber
●柜内电缆安装空间宽裕，电缆连接高度约600mm，每单元的电缆室之间用敷铝锌板隔开，便于维护和检修。剩余的大部分空间可装电流互感器及其它控制保护器件。
The cable chamber of cubicle is big enough for fitting cable, the connection height of cable can reach over 600mm, except the cable, the rest space can be use to fit the CT or other control and protection components if any. The cable chamber of each unit is isolated by Aluzine steel sheet to convenience for checking or maintaining.
●电缆的连接采用预制式电缆插接件，插接件可选用屏蔽型、非屏蔽型，也可加装避雷器。
The prefabrictad cable inserters, either shield type one or non-shield type one, are adopted for cable connections. The arresters can also be fitted here too.
●对于双电缆进线并加装避雷器，必须采用加深的电缆室盖板，电缆室的底部装有接地母排。
If double incoming cables and adding arresters, the deepening cable chamber cover should ba used. There is earthing busbars locating in the bottom of cable chamber.
断路器本体 Vacuum circuit breaker
●单个传动密封口，减少漏气几率。
There is only one sealling driving to be used, it reduce the gas leakage probability.
●改变传统的绝缘方式，不用绝缘拉杆，传动轴采用强度高，绝缘性能好的材料制造。
The driving shaft of vacuum circuit breaker is made of excellent insulation material with high strength, it is no longer a traditional insulation pulling rod.
●可以开断大的短路电流，保护大容量的变压器。
The VCB inside has high capacity to break havy short circuit current, so can be used for protection of big size transformer.
( 二) .3 安装及尺寸图Installation
●开关设备安装基础的施工应符合《电力建设施工及验收技术规范》中的有关条款规定
The foundation for cubicle should be in conformance with relative requirements stipulated in《The code of erection and
acceptance of electric power construction》
●柜体单列时，柜前走廊以1.5米为宜：双列布置时，柜间操作通道走廊以2米为宜
The corridor width in front of cubicles arranged in one row takes l.5m properly, and 2m proper for double rows arrangement
●一次电缆终端安装严格按相关工艺要求
The fitting of primary cable teerminals should be strictly according to relevant technology requirements
●电缆沟上方预埋10号槽钢，柜子放在槽钢上固定
The No. 10 U steels built in the top edges of cable trench can be used as the base of cubicle

产品在安装前要先检查产品前要先检查产品铭牌、 合格证是否与订货单相符，装箱单是否与实物相符。确 认无误后再清理表面灰尘污垢，然后观察产品的分合指 示是否指示正常，箱体是否变形等，然后装上手动储能 手柄先进行5次手动分合操作，再进行5次电动分合操 作。机械动作正常后，进行10kv/1 min工频耐压试验。其他试验根据用户实际情况，选择性进行，如：电压、电流互感器精度、极性及变比试验。检查完毕后即可安装。
产品安装过程中，不得翻转、倾斜，并要求采取防震措施。起吊时水平吊起。
