1.施工准备Preparationwork.开工前对全体参加该项目施工的人员进行技术和安全交底，并签字Priortocommencementoftheconstructionallpersonnelinvolvedintheprojectshouldparticipateintechnicalandsafetydisclosureandsignit..对施工图纸进行会审，确认无误后方可施工Theconstructiondrawingsshouldbereviewedandconfirmitcorrectbeforetheconstruction.检查施工器械工具等是否完备，土建预埋件是否符合设计要求Checkwhethertheconstructionequipmenttoolsarccompletedandscaffolderectionneedpasstheacceptance.各种工器具齐全、完好并经检验合格Allkindsoftoolsandinstrumentsarecompletedintactandalreadyinspected.
2.封闭母线运输IPBTransport
1.用汽车将封闭母线运至现场运至现场后按照吊装顺序摆放好并做好防护措施Transporttheenclosedbustothesitewithacar.Afterbeingshippedtothesiteheyareplacedintheorderoflifting.Andmakeprotectivemeasures.
1.母线不得任意堆放和在地面上拖拉，外壳上不得进行其他作业
3.封闭母线吊架安装Closedbushangerinstallation1测量发电机、主变压器中心线根据此中心线按设计图纸及厂家图确定母线中心线测量发电机出线标高，确定母线支架尺寸、位置，支架间距Measurethecenterlineofthegeneratorandmaintransformeranddeterminethebuscenterlineaccordingtothecenterlineaccordingtothedesigndrawingsandthemanufacturersdrawings.Measurethegeneratoroutputlineelevationdeterminethebusbarbracketsizepositionandbracketspacing..按厂家图纸安装母线支架，安装时注意随时测量，保证支架支承顶面水平标高与实际相符三相母线标高误差不大于5mm.Installthebusbarbracketaccordingtothemanufacturersdrawings.Payattentiontothemeasurementatanytimeduringinstallationtoensurethatthehorizontalelevationofthetopsurfaceofthebracketsupportmatchestheactuallevel.Three-phasebusheighterrorisnotmorethan5mm..顶部钢梁上焊接吊装母线的吊耳，吊耳采用d=5mm厚的钢板制作，吊耳位置根据母线位置合理分布，便于母线吊装吊耳必须焊接牢固，无漏焊、虚焊Theliftinglugsofthehoistingbusbarsarcweldedonthetopsteelgirder.Theliftinglugsaremadeofsteelplatewithd=5mmthickness.Thepositionofthelugisreasonablydistributedaccordingtothepositionofthe

4.封闭母线吊装IPBHoisting
1.封闭母线吊装由发电机侧开始根据厂家提供的图纸按照标号逐一吊装吊装时每一段的头尾不能颠倒由于封闭母线整体强度较差吊装时必须使用吊装带至少有两点起吊，以防外壳变形或损坏绝缘子Theenclosedbusliftingstartsfromthegeneratorside.Accordingtothedrawingsprovidedbythemanufacturerinaccordancewiththelabelliftingonebyone.Theheadandtailofeachsectioncannotbereversedduringlifting.Duetothepooroverallstrengthoftheenclosedbusbarshoistingstrapsmustbeusedtoliftatleasttwopointstopreventdeformationordamagetotheinsulators.
1.封闭母线不得用裸钢丝绳其吊和绑扎
1.Theenclosedbusshallnotbehungandtiedwithnakedsteelropes.
5.封闭母线找正Closedbusalignment
1.在主母线全部摆放到位后，进行全面的母线安装工作，保证母线相间距离为750mm.保证母线同一平面内为一直线，保证母线顶面同一标高，保证母线与主变升高座对11正确，保证母线与厂用分支对口正确封闭母线安放到构架上，应仔细丈量母线段的尺寸，当出现误差时不要把误差集中在断口或焊口上而是按比例分配在各断口中Afterthemainbusbarsareallinplaceconductafullbusbarinstallationworktoensurethatthebusbarshaveaphase-to-phasedistanceof750mm.Ensurethatthebusbarsareinastraightlineinthesameplaneensurethatthebusbarshavethesameelevationonthetopplaneandensurethatbusbarsandmaintransformersareseatedcorrectlytoensureproperalignment.Busbarsandfactorybranchesarecorrect.Closedbusbarsareplacedontheframeandthedimensionsofthebusbarsectionshouldbecarefullymeasured.Whenerrorsoccurdonofocustheerroronthefractureorweld.Insteaditisproportionedtoeachfracture.
1.外壳与导体不同心度不大于5mm，对口中心误差不大于
