The panel and main components can see in figure 3/1.Incoming-line panel or outgoing-line panel are diagram of 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 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。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 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 pressure 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-pressure area. Clapboard space isolate the VCB vault B with cable vault C, even if VCB. truck is movedhere 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 removed, 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 truck can be operated when the truck vault door is closed, while you can watch the position of the truck, on VCB tripping/offVCB 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 of it. The arm of spri
