【正文】 of longitudinal channel beam be agree with the dimension of switchgear body frame. 土建基礎(chǔ)工程完成后，由電氣安裝單位將加工好的基礎(chǔ)框架放在基礎(chǔ)平面上進行基礎(chǔ)框架安裝。使用鋼帶尺及水平儀校準框架水平及垂直方向的尺寸，要求水平誤差不超過每米1毫米，總誤差不超過3毫米。For the amount of switchgears is few, weight isn’t heavy, it is permit to install directly on the floor of distribution house. It is request that the floor is very flat and with enough carrying capacity. If needing, you may insert right shim under the switchgear while installing and adjusting. （圖5/5）的安裝 Installation of foundation frame at concrete level ground如圖5/5所示，開關(guān)柜的基礎(chǔ)框架埋設(shè)一般要求采取二次澆灌的方法，完成土建施工之后進行基礎(chǔ)框架埋設(shè)。The switchgears KYN2812 have two kinds of maintenance manners for double faces and single face. KYN2812 can be installed alongside wall, thus to save floor area. When it is permitted, collocation in switching room is advised to be designed with double maintenance for that channels for installation and servicing between the back cover board of switchgears and partition, between both side of switchgears and partition are be set aside.開關(guān)柜距墻要留有足夠?qū)挼耐ǖ?，對安裝運行和維護都較方便。If the maximum storage period starting from the date of packaging has been exceeded, the protective function of the packaging is no longer guaranteed. Suitable action must be taken if intermediate storage is to continue.5 開關(guān)柜的現(xiàn)場安裝Installation of switchgears at site為了保證正確安裝程序和最高安裝質(zhì)量，開關(guān)柜的現(xiàn)場安裝應(yīng)由經(jīng)特殊培訓的專職人員來進行，也可通知我公司派工程師去現(xiàn)場負責指導(dǎo)和監(jiān)護。Unpackaged devices are loosely covered with plastic film. Ventilation must be maintained for corrosion protection.216。 開關(guān)柜應(yīng)直立存放。First take apart the coverboard of packing box, second take apart the side boards around, last remove the bolt connected switchgear with underpan. Please notice that the socket bolts removed should be reinstalled in original locale and screwed up. Lift the switchgear vertically and separate it from the underpan. Then takeoff the underpan, put roll pole under the switchgear and prize slowly by wood stick, thus remove the switchgear to the insulation or stay position. Notice no heavier strike or libration in course of moving.簡易包裝或不包裝的開關(guān)柜Switchgears with basic packaging or unpacked216。Checking the delivery for pleteness and damage. Checking the marker, conformity certificate and instruction manual of switchgears for exactness and pleteness. If you doubt, please open box and check. Put in drier and reseal the box when intermediate storage. 216。 起吊開關(guān)柜時，允許吊耳有相應(yīng)的彎曲。Crane, fork truck or manual hanger frame.216。 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(guān) 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(jié)構(gòu)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(gòu)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(dǎo)向桿 Guide bar 圖3/2低壓室內(nèi)部視圖，端子排座可向上旋轉(zhuǎn)以便輔助開關(guān)的安裝，控制線的布線和接線Figure 3/2 Intramural view in lowpressure chamber.

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(guān)柜。電纜室也可安裝避雷器。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。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.
