5、DL404等标准。开关柜外壳的防护等级为IP4X，当断路器室门打开、手车移开时，防护等级为IP2X。在系统的安装和运行期间，要遵守所有相关的IEC规范及国家或地方相关的安全导则，还应考虑江苏银佳企业集团有限公司提供的有关资料。1.3工作条件1.3.1 正常工作条件 KYN28-12开关柜正常工作条件如下：室内环境温度：最高温度 +40°C日平均值不大于 +35°C最低温度 -15°C室内环境湿度： 日平均相对湿度 95%及以下 月平均相对湿度 90%及以下Monthly average relative humidity less than 90%安装场所的海拔高

6、度 1000m及以下Height above sea level at site less than 1000m地震烈度: 不超过8度Earthquake intensity: less than 8 degree没有火灾、爆炸危险，没有严重污秽及化学腐蚀的场所。This product should not be used under conditions of fire, explosion，earthquake and chemical corrosion environments.1.3.2特殊工作条件Special service conditions对特殊工作条件，必须向制造厂咨询

7、。制造厂与用户应就特殊工作条件取得一致意见。The manufacture must be consulted in advance about each special service condition. Special service conditions are to be agreed on by the manufacturer and user. l 已考虑安装场所的海拔高于1000m时，空气介质强度的降低对绝缘水平的影响。Allow for the reduction in the dielectric strength of the air when site altitud

8、e is over 1000ml 若环境温度超出极限值，在母线和分支母线的设计上加以补偿或限制载流量。在柜内安装通风装置将有利于开关柜的散热。If the ambient temperature is over top of the high-point, must consider equalizing or limiting current capacity for the design of main bus bar and branching bus bar. Installation the aerator is favor of rejection of heat.1.3.3 注意

9、事项：Matters need attention：若开关柜运行地区的湿度较高，温度波动速度较快且幅度较大，开关柜在这种气候环境下运行，就有凝露的危险，因此开关柜在备用和运行状态下，用户应保证加热器全天侯投入！但在大电流运行中，可以不投入。If the humidity is higher on site, temperature fluctuations speed is rapidder and range is bigger, condensation phenomena will be appear for the switchgears running in this clime c

10、ondition, so user should ensure that the heater running full time on spare and running condition! But running in high-current, the heater can stop. 2技术数据 Technical data2.1 开关柜电气参数 Switchgear technical data额定电压kV12额定绝缘水平1min工频耐压（有效值）kV42雷电冲击耐压（峰值）kV75额定频率Hz50主母线额定电流A630,1250,1600，2000，2500，3150，4000分

19、安装的电气元件见图3/1。进线柜或出线柜是基本柜方案，并有派生方案，如母线分段柜或计量柜等。此外，尚有配置固定式负荷开关、真空接触器手车、隔离手车等方案。开关柜靠墙或面对面安装。结构细节和柜内安装设备，可见订货文件。The basic structure of switchgear panel comprises the panel itself a removing part. The panel and main components can see in figure 3/1.Incoming-line panel or outgoing-line panel are diagram o

20、f basic switchgear panel，there are other derivative diagram，for example ,contact panel or metering panel .in addition，There are so many diagram of the switchgear panel with stationary type load switch、（SF6）VCB truck、VC truck、Disconnect truck. The panel has two maintenance modes. That is single-face

21、maintenance and double-face maintenance. The detail of structure and main components, can reference order document.3.2外壳和隔板 Enclosure and clapboard开关柜的外壳和隔板由优质钢板制成，具有很强的抗氧化、耐腐蚀功能，且刚度和机械强度比普通低碳钢板高。三个高压室的顶部都装有压力释放板。出现内部故障时，高压室内气压升高，由于柜门已可靠密封，高压气体将冲开压力释放板释放出来。相邻的开关柜由各自的侧板隔开，拼柜后仍有空气缓冲层，可以防止开关柜被故障电弧贯穿熔化。

22、低压室D装配成独立隔室，与高压区域分隔开。隔板将断路器室B和电缆室C隔开，即使断路器手车移开（此时活门会自动关闭），也能防止操作者触及母线室A和电缆室C内的带电部分。卸下紧固螺栓就可移开水平隔板，便于电缆密封终端的安装。The enclosure and clapboard of the switchgears is made up from high quality steel, have very strong function to resistant oxidation and corrosion, and its rigidity and mechanical robustness

23、is higher than common low-carbon steel board. Have been installed release of pressure plate on the top of three high-pressure chambers. When appear internal fault electric arc, air pressure heightens in high-pressure chamber, because that the doors of switchgear is already airtight coating, the pres

24、sure gas will clash out the release of pressure plat. Adjacent switchgears are isolated by its self side board, after putting the switchgears together, air buffer layer exist yet, it may prevent the switchgears from pronging and melted by electric arc. Low-voltage vault D is separate room with high-

25、pressure area. Clapboard space isolate the VCB vault B with cable vault C, even if VCB. truck is moved(here the valve is closed self-motion),can prevent the operator from touching the electrification parts of bus bar vault A and cable vault C. releasing the tighten bolt, the level clapboard is remov

26、ed, convenient for installation of cable seal terminal.3.3开关柜内的小室 Compartments in switchgear断路器室（见附图3/1，3/3，3/5，3/6）VCB vault (figure 3/1，3/3，3/5，3/6 showing)断路器手车装在有导轨的断路器室B内，可在运行、试验/隔离两个不同位置之间移动。当手车从运行位置向试验/隔离位置移动时，活门会自动盖住静触头，反向运行则打开。手车能在开关柜门关闭的情况下操作，通过门上的观察窗可以看到手车的位置、手车上的ON（断路器合闸）/OFF（断路器分闸）按钮、合分

27、闸状态指示器和储能/释放状况指示器。VCB truck is installed in VCB vault B with track, may move in the middle of the position to service and test/disconnected. While the truck move from service position to test/disconnected position, the valve can cover un-move contact in self-motion, open when moving reverse. The tru

28、ck can be operated when the truck vault door is closed, while you can watch the position of the truck, on (VCB tripping)/off(VCB closing) push knob in the truck, close and open indicator and charging/releasing indicator by inspection window. 断路器手车 VCB truck手车可采用手动进行移动。框架由合金钢板拼装而成，上面装断路器和其他设备。具有弹簧触头系

29、统的触臂装在断路器的极柱上，当手车插入到运行位置时起电气联接作用。手车于开关柜之间的信号、保护和控制线，用一个控制线插头联接。手车刚插入开关柜就固定在试验/隔离位置，同时也可靠地联接到开关柜的接地系统。手车的所在位置，能通过观察窗或装在低压室面板上的手车电气位置指示器看到。除真空断路器外，手车可配真空接触器、隔离装置和计量设备等。The truck can be moved by manual. The structure of the truck is made of the steel, the VCB and other equipments are installed on top o

30、f it. The arm of spring bush is installed on the pillar of the VCB，When the truck is pushed on the service position, it has the effect of electrical interlocking. The signal 、protection、control line between the truck and the switchgear is connection with the pin of control line. The truck is fixed o

31、n the test position as soon as it is pushed into the switchgear, and be connection to the earth system of the switchgear. The position of truck will be seen by the lamp that is installed on the looking window or the panel of low-voltage.Beside the VCB, the Truck can be equipped the vacuum contactor

32、、isolated device and the measuring equipment.母线室 Bus bar compartment母线从一个开关柜引至另一个开关柜，通过分支母线和套管固定。矩形的分支母线直接用螺栓联接到主母线上，不需任何联接夹。所有母线和分支母线都用热缩套管覆盖。套管板和套管将柜与柜之间的母线隔离起来，并有支撑作用。对电动应力大的开关柜，一般需要这种支持。The bus bar from one switchgear to the other switchgear is fixed with the bushing and the ramus bus .The ramus

33、 bus is connection to the main bus with the bolt, it neednt any clip. All bus and the ramus bus are covered with pyrocondensation bushing. The panel of bushing and bushing are isolated between the switchgear and the switchgear. And it has the effect on supporting.电缆室（图3/1）Cable compartment（drawing 3

34、/1）电流互感器和接地开关装在电缆室后部。电缆室也可安装避雷器。当电缆室门打开后，有足够的空间供施工人员进入柜内安装电缆（最多可并接6根）。盖在电缆入口处的底板可采用非导磁的不锈钢板，是开缝的，可拆卸的，便于现场施工。底板中穿越一、二次电缆的变径密封圈开孔应与所装电缆相适应，以防小动物进入。对于湿度较大的电缆沟，建议用防火泥、环氧树脂将开关柜进行密封。CT and earth switch are installed on the back of the Cable Compartment. The Surge arrester is also installed on the Cable C

35、ompartment. When the truck and the horizontal panel are moved .There is enough room so that the worker install the cables (the most is 6).The bottom of panel that lie on the incoming of cable in made of the stainless steel panel，It is uncork, disassembly so that working on the local. The airplane of

36、 panel where is together secondary cable make sure as same as the installed cable prevent the small animal being into it.For the cable trench in humidity，It is suggested that the switchgear is airproofed with fireproofing mud and epoxide resin.低压室（图3/1、3/2） Low-voltage compartment (figure 3/1、3/2)开关

37、柜的二次元件装在低压室内及门上。控制线线槽空间宽裕，并有盖板，左侧线槽用来引入和引出柜间连线，右侧线槽用来敷设开关柜内部连线。低压室侧板上有控制线穿越孔，以便控制电源的联接。Low-voltage components of switchgear are installed in low-voltage compartment and on door. Control wiring trunking has ample space and cover board. Nearside wiring trunking is used to introduce and educe the wirin

38、g between switchgears, starboard wiring trunking is used to lay intramural wiring in switchgear. Traversing hole for control wiring on side board in low-voltage compartment is used to connect with control power supply.3.4防止误操作的联锁/保护 Interlocks/protections for preventing mishandling具备一系列的联锁装置，从根本上防止出

39、现危险局面和可能引起严重后果的误操作，因此有效地保护了操作人员和开关柜。联锁装置地功能如下：A series of interlocks are provided to prevent mishandling, thus protecting both personnel and switchgear itself. The function of interlocks is following: Ø 断路器和接地开关在分闸位置时，手车能从试验/隔离位置移动到运行位置。在这种分 闸状态下，反向移动也行（机械联锁）。 VCB and earth switch in the OPEN p
