哈纳斯变电所施工方案(编辑修改稿)内容摘要：

rror of the whole length is 15mm. (include horizontal and vertical levels), It is not suitable that cut material with gas welding to avoid change shape. 基础型钢的组对焊接应有 熟练的焊工施焊。 变压器的基础型钢外框和盘柜基础同时制作。 Assembly and welding of support shape steel on foundation shall be carried out by skilled welder. Transformer support out frame and cabi support fabricated together. 变压器就位和附件安装 Transformer Located amp。 Accessories Installation 变压器前 吊装 检查变压器的基础道轨宽度与变压器道轨宽度一致。 变压器就位固定必须依据图纸尺寸进行 ,对没有设计具体尺寸的则应根据变压器二次出线的 B 相与中压进线盘的B 相对准。 确定位臵后，应用角钢将变压器固定在基础槽上。 Check the support track size match to transformer track size or not, transformer located ply with drawing, if there isn’t detailed size, it should according to the Bphase of transformer secondary outgoing cable match Bphase of MV inlet cabi. After location confirmed, fix the transformer on the support by anglesteel. 变压器在安装合格以后，进行附件安装：由于 110KV 变压器是接线箱、油箱、散热片、温度计等附件均是分体的。 所以安装附件是变压器安装的一个重要环节。 使用 25T 吊 车（因最重的油箱盖是 ）配合安装变压器附件，附件安装时注意密封，尤其是油路的密封件一定齐全、可靠。 此安装厂家配合。 所有的安装附件完成后，取本体变压器油和待注入的油各一瓶（ 500g），送专门检验所做油混合试验，待绝缘油检验合格后，进行注油，注油时注意油标的指示，按照厂家的要求，注至油位。 注油完毕， 24 小时后，检查变压器是否有渗漏，否则需进一步处理，正常方可进行下道工序。 After transformer installation qualified, install the accessories: due to the junction box, oil 中国 第十一建设有限公司宁夏哈纳斯工程项目部 化 学 工 程 China Eleventh Chemical Construction Company Limited NingXia Hanas Project 12 / 29 box, radiation fins and thermometer of 110Kv transformer is separated, so accessoried installation is key to transformer installation. We plan use 25t mobile crane assist accessories installation (the heavyest oil box cover is ), pay attention to seal while accessoried installation, especially the oilway seal fits have to pletely and properly. After accessories installation finish, sampling oil from transformer body and infuseoil 500g, send to oil mix examinating by professional lab, oiling after examined, oiling to scale according to manufacturer. After 24 hours from oiling finish, check the leakage, go to next procedure if in good condition. 就地的温度计只需在温水里面试验一下保证读数正确，即可安装，安装时在温度计套管里面放少许变压器油即可。 远传温度计，需要用万用表检查一下低温 /高温节点是否可靠， 限位点设臵的是否合适，温度计应根据设计数值或出厂规定进行整定。 温度计盘面应对着巡检易视处，金属毛细管的弯曲半径不得小于 50mm。 监视或保护变压器的二次电缆外引线、排列应整齐，应有保护措施，接线盒应密封良好，端子接线有标识。 接线时一定分清公用线和高 /低温线。 压力释放装臵出厂已装好，且出厂时已做试验，现场只需检查引出电接点动作是否正确。 压力信号接点应动作正确，导通良好。 接线箱安装主要是保证不能碰到瓷瓶，螺栓固定牢靠。 油箱的位臵保证是设计位臵，保证油箱内没有杂物。 Local thermometer test in water bath to ensure the correct reading and then installed, oiling into thermometer sleeve. 10KV 变压器的安装，由于是干式变压器，变压器按照设计位臵固定后，安装温控器，检查散热风扇齐全即可。 10Kv transformer is dry type, after transformer fixed according to design position, install the thermometer, check the cooling fan. 电气盘柜及 GIS 系统安装 /Electrical Cabi amp。 GIS System Installation 基础型钢安装 Installation for section steel on foundation 本变电所的 电气盘柜及 GIS 系统的 基础型钢设计是 10槽钢，安装的方式是立式安装，型 中国 第十一建设有限公司宁夏哈纳斯工程项目部 化 学 工 程 China Eleventh Chemical Construction Company Limited NingXia Hanas Project 13 / 29 钢安装后，先进行防腐处理，然后进行面漆处理。 Electrical cabi support and GIS shape steel support of substation designed as 10 channel steel and installation in vertical, painting and touchup after shape steel installation. 在钢制平台上将型钢的平面及立面分别平整，校直，全长偏差控制在 15mm 之内（包括平面和立面）。 Leveling and alignment of shape steel on steel work plateform, control the error under 15mm (plane and side) 下料时尽量少用气割，以减小型钢的变形度。 Section steel shall be leveled and lined on steel plate, the allowable error of the whole length is 15mm. (include horizontal and vertical levels) It is not suitable that cut material with gas welding to avoid change shape. 基础型钢的组对焊接应有熟练的焊工施焊。 型钢与支腿之间采用钢板过渡，为方便运至现场，型钢应分段制作。 Butt connection of section steel on foundation shall be carried out by skilled welder. Section steel shall be fabricated in sections to be convenient for transportation. 严格按照施工图所示尺寸，并结合制造 厂产品样品，测量各种盘柜的准确尺寸，尤其是确保母线桥的安装尺寸。 Section steel shall be fabricated base on construction drawing or manufacture’s requirement or the actual size of the panel, where there is bus, the installation size shall be ensured. 采用测平仪测量室内地坪的高低差，找出标准点后，按设计高度进行找平。 本装臵的预 埋铁土建已经埋设完成。 Measure the difference level of the floor by level, choose a point as reference, level it according to design height. Embeded steel of this project finished by civil constructor 基础型钢的找平应采用垫铁找平，分段找平直采用点焊，待整体找平后再进行最后焊接。 Levelingoff of shaped steel foundation shall use liners, when leveling in sections, use spotweld after the whole foundation is leveled, weld pleted. 基础型钢的安装应符合下列要求： Installation of section steel on foundation shall ply with the following requirement: a、基础型钢安装的允许偏差 中国 第十一建设有限公司宁夏哈纳斯工程项目部 化 学 工 程 China Eleventh Chemical Construction Company Limited NingXia Hanas Project 14 / 29 项目 允许偏差 mm/m mm/全长 不直度 〈 1 〈 5 水平度 〈 1 〈 5 位置误差及不平行度 〈 5 a Deviation allowance for shaped steel foundation: item allowance mm/m mm/whole length alignment 1 5 levelness 1 5 location error and parallelism 5 b、基础型钢安装后，其顶部宜高出地平面 10mm，手车式成套柜按产品技术要求进行。 The roof of installed foundation shall be 10mm higher than level of floor. The installation of foundation for trunktyped assembled panels shall accord to technical requirement. C、基础型钢应有明显的不少于两点的可靠接地。 The section steel on foundation shall be grounded tightly by at least 2 points. 与盘柜安装工程有关的建筑工程的施工，应符合下列要求： Relevant building for panel installation is accordance with requirement as following: 与盘柜安装有关的建筑物、构筑物的建筑工程质量，应符合国家现行的建筑工程施工及验收规范中的有关规定。 The construction quality releated building, structure to cabi installation should ply with state existing regulate of construction and acception. 屋顶、楼板施工完毕，不得渗漏。 室内地面工作结束，室内沟道无积水、杂物。 Roof, floor construction finished, it can’t have leakage, internal flooring finished, ditch clean and no sundries and seeper. 预埋件及预埋 孔符合设计要求。 门窗安装完毕。 进行装饰工作有可能损坏已安装设备或设备安装后不能再进行施工的装饰工作已全部结束。 Roof floon pleted and no leakage, floor work pleted。
