Cubicle composed of two parts: fixed cubicle enclosure(abbreviation as cubicle body) and removable parts(abbreviation as trolley). The cubicle body can be divided into four function unit according to the function of the electric device, and the cubicle body is separated by the steel plate to be four different function unit as main bus-bar chamber A , trolley chamber B, cable chamber C and meter chamber D in Fig.1. the enclosure of the cubicle body and each function unit are made of aluminum-zinc metal plate by riveting method.
Vacuum circuit breaker, SF6 circuit breaker, Voltage transformer, lightning arrestor and trolley can be assembled with cubicle.
The protection class of enclosure of the cubicle is IP4X, the protection class is IP2X while the gate of the circuit breaker chamber is opened.
The influence of inner fault arc in cubicle has been taken in consideration 8
on the side of structure, and strict arc test has been done according to the regulation in IEC62271-200 to ensure the safe of the worker and device. The outline of cubicle vide Fig.1, the out line of circuit breaker vide Fig. 2 开关柜的外形尺寸和质量如下：
所用变柜的宽度一般为1800mm
The width of the station-type normally is 1800mm
4.2 外壳、隔板及压力释放装置
开关柜的外壳和隔板是采用敷铝锌板经CNC机床加工和折弯之后组装栓铆而成。因此，装配好的开关柜能保证尺寸上的统一性，有很高的机械强度。
开关柜的门板面漆采用静电喷涂后焙烤，表面抗冲击、耐腐蚀性能好，外形美观。
在断路器室、母线室和电缆室的上方均设有压力释放装置，当发生内部故障时，伴随电弧的出现，开关柜内部气压升高，顶部装设的压力释放金属板将被自动打开，释放压力和排泄高温气体。以确保人员和开关设备的安全。
4.2 Enclosure, separator and pressure releasing device
Enclosure of cubicle and separator adopt aluminum-zinc metal plate machine-shaping and bending by riveting method to ensure the same dimension of the assembled cubicle with advanced mechanical intensity.

开关柜的二次线与手车的二次线联接是通过二次插头来实现的。二次插头的动触头装于手车上，二次插座装设在开关柜断路器室的右上方。当手车处于“试验/隔离”位置时，才能插上和拔下二次插头。手车处于“工作”位置时，二次插头被锁定。当断路器手车安装有闭锁电磁铁时，在二次插头未接通之前，由于闭锁电磁铁未通电，无法手动合闸，仅能进行手动分闸操作。
4.3 circuit breaker chamber
Special attached rail device has assembled the lower side of the circuit breaker chamber to let the trolley enter in the cubicle. Upper and lower static contact box and metal active gate mechanism fixed set in the chamber, while trolley is at the test position or move-out position , active gate can be closed reliably to ensure the safe of the worker in the trolley chamber. While trolley
12
enter in the chamber, active gate can open automatically to ensure the getting through the static contact. The slice guide rail of trolley and earth conduct plate fixed on the bottom of the circuit breaker, the earth conduct plate connect to the earth contact of trolley and earth bus-bar of the whole cubicle.
The pushing mechanism of trolley and locating device is at the middle part of left and right pole which in the front of the cubicle. If earth switch selected, the operating mechanism of earth switch and its mechanism inter-lock will be put in the middle of the right side of the chamber.
Trolley can be operated while the door of the cubicle is at the close position, we can see the position of the trolley in the cubicle and CB opening/closing direction, the energy-storing spring’s energy storing/releasing direction through the inspection window.
The connection of secondary loop of cubicle and secondary loop realized by the secondary plug, the moving contact of secondary plug is assembled on the trolley, secondary socket is set at the right upper-side of the CB chamber, while trolley is at the test/disconnect position, the secondary plug can be put on of taken off, while the trolley is at the working position , the secondary plug has been locked tightly. While lock out device has assembled on the trolley, before the making of the secondary plug, for the lock out electric-magnetic iron are not at the making condition, so it can not be closed by hand, only opening operating can realized.

13
手车框架由冷轧钢板经折弯焊接制成。根据用途，手车可分为断路器手车、电压互感器手车、隔离手车等。各类手车的高度与深度都统一，相同规格的手车能互换。
断路器手车在柜内有“工作”位置和“试验”位置，每一位置均设有定位闭锁装置，保证手车处于特定位置时才允许进行移动。
手车必须满足联锁条件，保证手车移动之前断路器必须先分闸。 断路器手车推入手车柜内时，首先处于“试验”位置，然后由摇动手把将手车推入“工作”位置。
手车在柜内的位置既能从仪表室面板上的位置指示器指示，也能从门上的观察窗看到。断路器的机械操动机构、分合闸指示器在手车的面板上。
4.4 trolley
Frame of trolley are made of steel plate by bending and welding methods, trolley can be divided into four kinds according to its usage: circuit breaker trolley, voltage transformer trolley, isolator trolley and etc. each kind of the trolley has the same height and depth, to the can be exchanged freely.
There’s working position and test position in the CB trolley, each position has locating lock out device to ensure the trolley can be moved only at the regulated position.
Trolley should be satisfied with inter-lock condition, before the move of trolley, CB must be open first.
While the trolley is pushed into the trolley cubicle , first let it locate at the test position, then rotate the handle to push the trolley to the working position. 14
The position of trolley can be checked from the direction of position director which on the face-plate of meter chamber, also it can be seen from the inspection window, the director of the operating mechanism and open/close direction of CB is on the face-plate of trolley.
4.5 触指系统
开关柜一次回路中的静触头和手车上的动触头之间的导电装置采用花瓣式触指系统。触指系统结构设计合理，具有接触电阻小，承受短时耐受电流及峰值耐受电流大等优点，电气性能稳定。当手车摇入或摇出时，触指系统接触或分离自如，手车操作非常方便。
4.5 contact system
Petal-type contact system adopted for conduct device between the static-contact and move-contact which in the primary circuit of cubicle which is reliable designed with less contact resistance and strong bearing of short time withstand current and peak withstand current as well as advanced electric function. While trolley push in or out, contact system can touch or separate freely, operating of trolley can be operated conveniently.
4.6 母线室
主母线分段贯穿于相邻的柜之间，由分支母线及支柱绝缘子和穿墙套管支撑。
柜与柜之间通过穿墙套管及隔板达到互相隔离的目的。
主母线根据额定电流的大小可采用单根或双根铜质或铝质的矩形母线。主母线和支母线采用收缩型绝缘套管工艺，静触头盒出线侧三相相间 15
