y in accordance with IEC 298 or GB3906 except that it is checked in accordance with order form, thus verifying their correct structure and function. Bus bar, fastening piece and accessory are packed by oneself. Packaging 開關柜的包裝按具體情況的要求作相應的調(diào)整,如航海包裝或不包裝。 Some additive interlocks can be assembled on the truck and/or earth switch operating mechanism, as case electromagnet, user should provide the required information when ordering. 隔室:CompartmentA母線室 Bus bar partment C電纜室 Cable partmentB斷路器室 Truck partmentD低壓 Lowvoltage partment主要部件:Master parts1母線 Bus bar 2絕緣子 Insulator3靜觸頭 Fixed contact4觸頭盒 Bush 5電流互感器 Current transformer6接地開關 Earth switch7電纜終端 Cable terminal 8避雷器 Arrester 9零序電流互感器 Zero-sequence current 10斷路器手車VCB truck滑動把手 Slip handle鎖鍵(聯(lián)到滑動把手)Lock key(link to sliding handle)11控制和保護單元 Control and protection unit12穿墻套管 Wall bushing圖3/1:KYN2812進線或出線柜基本結構剖面圖Figure3/1:Basic structural sectional view of ining line or outgoing line主要附件:Master accessories13絲桿機構操作孔Operation hole of screw machine14電纜夾 Cable grip電纜密封圈 Cable lockring 連接板 Connection board16接地排 Earth bus 17二次插頭 Control wiring plug聯(lián)鎖桿 Interlock lever 18壓力釋放板 Pressurerelief plate19起吊耳 Flying rings20運輸小車 Transport cart鎖桿 Lock bar 調(diào)節(jié)輪 Regulating wheel導向桿 Guide bar 圖3/2低壓室內(nèi)部視圖,端子排座可向上旋轉以便輔助開關的安裝,控制線的布線和接線Figure 3/2 Intramural view in lowpressure chamber.

On this state, it is be able to move reversely yet(electric interlock). 216。 斷路器和接地開關在分閘位置時,手車能從試驗/隔離位置移動到運行位置。Lowvoltage ponents of switchgear are installed in lowvoltage partment and on door. Control wiring trunking has ample space and cover board. Nearside wiring trunking is used to introduce and educe the wiring between switchgears, starboard wiring trunking is used to lay intramural wiring in switchgear. Traversing hole for control wiring on side board in lowvoltage partment is used to connect with control power supply. Interlocks/protections for preventing mishandling具備一系列的聯(lián)鎖裝置,從根本上防止出現(xiàn)危險局面和可能引起嚴重后果的誤操作,因此有效地保護了操作人員和開關柜??刂凭€線槽空間寬裕,并有蓋板,左側線槽用來引入和引出柜間連線,右側線槽用來敷設開關柜內(nèi)部連線。對于濕度較大的電纜溝,建議用防火泥、環(huán)氧樹脂將開關柜進行密封。蓋在電纜入口處的底板可采用非導磁的不銹鋼板,是開縫的,可拆卸的,便于現(xiàn)場施工。電纜室也可安裝避雷器。對電動應力大的開關柜,一般需要這種支持。所有母線和分支母線都用熱縮套管覆蓋。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 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 on 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 lowvoltage.Beside the VCB, the Truck can be equipped the vacuum contactor 、isolated device and the measuring equipment.母線室 Bus bar partment母線從一個開關柜引至另一個開關柜,通過分支母線和套管固定。手車的所在位置,能通過觀察窗或裝在低壓室面板上的手車電氣位置指示器看到。手車于開關柜之間的信號、保護和控制線,用一個控制線插頭聯(lián)接。框架由合金鋼板拼裝而成,上面裝斷路器和其他設備。手車能在開關柜門關閉的情況下操作,通過門上的觀察窗可以看到手車的位置、手車上的ON(斷路器合閘)/OFF(斷路器分閘)按鈕、合分閘狀態(tài)指示器和儲能/釋放狀況指示器。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 mon lowcarbon steel board. Have been installed release of pressure plate on the top of three highpressure chambers. When appear internal fault electric arc, air pressure heightens in highpressure 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. Lowvoltage vault D is separate room with highpre
