4.1、Procedures and Notice of Equipment Installation

4.1.1、The following tools and equipments should be prepared in advance before installation:

Crane,Wrench,Torque Wrench,Sleeve Wrench(24#、19#、17#、14#）,Screwdriver,Wooden Hammer,Track level bar,Square, Emery paper,Copper Brush(or Steel Brush),Cleaning cloth, Painting equipments,Argon arc welding equipments,Welding Machine,Cleaning tools,Conductive paste,Fluid sealant, Asbestos Cloth,Bus location Supporter,Rope or Steel ropes with rubber bushing.

4.1.2、The welding of Bus and Shell should be done by qualified

argon arc welder.The filth and Oxide film at the welded junction should be cleaned before welding.The purity of filling welding wire should not be lower than L2(not lower than99.5%).While the ambient temperature is lower than10℃,in order to ensure the quality of welding wire,measurements such as raising temperature before welding and heat preservation during welding should be taken.The total cross section of welding wire should not be smaller than1.25times of that of the welded conductor’s total section.

4.1.3、To ensure the installation quality,installation personnel should stick to the following principles:

4.1.3.1、Construction workers participated should strictly follow the

Equipments unpacking and acceptance

Familiar with drawings,construction standards and installation instruction

check civil construction and manufacturer’s drawing dimension Installation tools and construction preparation

Installation on Steel beam and supporting structure：

Lifting and location of enclosed busbar

Lifting and location,adjusting and connections on PT cubicle,LA cubicle,Neutral point cubicle,slightly positive pressure cubicle,air compressor.

4.1.4Installation of bus supporting steel girder

For the Installation of bus supporting steel girder,in accordance with the construction drawing,they should be pre-welded and fixed to the Steel structure supporter in the bus civil construction corridor,meanwhile,fund the unified horizontal level to lay the bus.

4.1.4.1、Installation order

The installation order should be in accordance with General Assembly Drawing.Section by section check bus components, phase order and order No.,then section by section assembly and

positioning them.Installation order should be better to begin from Generator outlet box(or from transformer,or exciter or Switch Cubicle).The head and end of each section should not be reversed.Before installing and swinging,the inside dusts and sundries in each bus section should be carefully cleaned.For Site General Assembly Schematic Diagram of Enclosed busduct,pls see drawing1

4.1.4.2No Knocking and Scratching on the Silver plating bolted surface of Bus clamp terminal in lifting are permitted,and do not randomly filling either.When connecting,remove the protection packing on the bus clamp terminal,then clean the silver-plated surfaces of terminals and copper braided wires,then paint conducting fat to the sliver plated surfaces of all terminals.Install copper braided wire terminal,fix the bolt and nut plate with torque wrench,its fastening torque value should be in accordance with the specification of list1

4.1.5、The connection of Shell section and section should be connected with bolt and fixed the bolt with torque wrenches(its torque value should comply with List1).After the section connection,install the rain cover,then Sealing the maintenance hole.Do not add sealing strip to the interface of outside vertical section rectangle maintenance hole bottom in order to avoid rain flowing into the bus.

4.1.6、The Section connection of conductor should be connected with bolt.And bolt surface of the junction panel should be painted with electrical fat so that the shell can be integrated electrically, then to fix the bolt with torque wrenches.(fixing torque value comply with list1)

4.1.7、For installation of Electric trace heating non-segregated bus,pls see its installation and using instruction.(if have)

4.2、Procedures and Notice of Equipment Adjustment

4.2.1、Adjustment Procedure

Adjust the distance between each section shell and

conductor according to manufacturer’s drawing size

4.2.1.2、First adjust shell distance,connect shells and locate (weld)the shell fixing feet.

4.2.1.3、Adjust conductor

4.2.1.3.1、First loosen the bolt of fixed conductor on each insulator, then adjust the conductor to a suitable place.

4.2.2、Notice

When adjusting the conductor,pls don’t damage its silver-

plated surface.

4.3、Procedures and notice of equipment start-up

4.3.1、Before starting-up the equipments,they must be through insulating resistance test and voltage withstand test,after certified can they be connected with other equipments.

4.3.1.1、Check and confirm installation according to the bus general layout drawing and Electric connection drawing. Connections must error-free.

4.3.1.2、The Bus,shell,isolator and sealing structure should be complete,clean,no dirt and filth.Clean the articles on the equipments and bus corridor that hinder bus operation,inspection and maintenance.Before closing the grounding knife,pls inspect whether the drawing and inserting of grounding knife is good and locking device is reliable to ensure complete,good and safe.

4.3.1.3After installation,the outside bus shell(aim at welding seam,shell connection,isolator mounting hole,maintenance hole etc.)should be withstand artificial rainfall test.In test,use a tube(diameter2.5cm),through a nozzle about3m away from shell, spray out the water horizontally from an45°angle with Water press keep at1.1Mpa.Spray consecutively5minutes to two sides along bus length way.There should be no water penetration trace inside

the shell.

4.3.1.4、Isolated resistor test:After installation,measure the isolated resistor of each phase conductor to shell by a2500V megameter.Its value should not be lower than100MΩ.

4.3.1.5、Power frequency withstand voltage test:The test withstand voltage value of commissioning and acceptance should be75%of that value in factory.

4.4、Procedures and notice for Equipment Starting-up

4.4.1、After the starting-up of equipment,the temperature of seams should be observed timely.If it overpasses the standard value,pls analyze the cause and treat it in time.

4.5、Equipment operation test and notice

When the equipments operate in normal,start up the thermostatic automatic control device.

4.6、Operation procedure and notice of equipment normal stop 4.6.1、When equipments stop normally,we need not do any operation.

4.7、Operation procedure and notice for equipment emergency

stop

4.7.1、When equipments stop in emergency,we need not do any operation.
