5.1 Product load and discharge can take by crane,travelling crane and others device,and strict meet national requirement process.
5.2When transportation, if with package carton, should mark on each angle.
6. Inspection before receive
when customer get the transformer, should inspecti it.
6.1 Package and moistureproof well,no water invade trail.
6.2 Check the product label such as the model rated capacity, rated voltage,connection no.anti-voltage,outside size,construction,weight and other whether meet contract requirement or national standard.
6.3 Check the instructon, test confirm,test report,packing list and others documents
6.4 Check the accessory, back up product specification, quantity, whether same as packing list.
6.5 Check whether have damage when transportation,the accessory damnify ,start,rupture,insulated whether have broken and so on.
6.6 After inspection all, if not put into operation, sould package well and store.
7. Product install
7.1 Should read this instruction, product label, outside size before installing, know the weight, how to install and others,ready to others device and tools.
7.2 the basic instruction must be meet load, shockproof,ventilation requirement..
7.3 Indoor ventilation and fire protection meet relative requirement,ventiduct airproof well,vent hole don't connect with others air system.
7.4 Temperature control,temperature show device should put obviousity place, easy to check.
7.5 inddor liging disposal meet relative regulate.
7.6 inddor take fire-resist material, door to ourside and label decive name, safe warning,protective net door and others safety establishment.
7.7 When connect transformer to electric device, the electric device should meet design requirement and relative point.
7.8 Conductor fix well and phase colour should clearly.
7.9 the distance between the electric phase and against earth meet relative design requirement,connecting earth should fix well.
7.10 The power of temperature device should from the femal rank side transformer,have enough capacity to fuse operation, and tale change to double power automatic according to the emergengy degree.
8.Inspection before operation
8.1 Measure all tap change,meet nameplate change rule,and rated tap allow error is ±0.5%,the rest allow error is less than1%.
8.2 Test the 3 phase transformer connecting or the pole of single transformer ,meet nameplate requirement.
8.3 Measure the insulated resist of coil, the value more than 70% test value.
8.4 Measure the iron coil insulated resist, the value more than 5MΩ.
8.5 Outside press anti-voltae test, the test voltage should be 85% of test voltage.
8.6 About the load regulate voltage transformer, should according to the load regulate tap switch instruction to put into test check and test.
9.Test operation
9.1 Before operation, should according to the nameplate and tap direction label to make tap slice into correct position.
9.2 when unload regulate voltage, should according to electric net voltage to make regulate voltage tap slice,nameplate and tap direction to make correction position.
9.3 Load regulate voltage, should according to load voltage tap switch instruction, tao swutcg test wekk after shut power ,then can put into operation.
9.4 the transformer have temperature control box and temperature show,please check attached instrciton,when temperature is normal, put the transformer operation at first, then put into temperature control and shower.
9.5 After transformer operaion,the load shoud from light to heavy, don't make one big load blindness.
9.6 Over load should meet GB/T17211 (dry type transformer load rule)
9.7 After transformer stope operation, no need take others action to put into operation again, but if higher humid and transformer have cold already, so should take dry action, then transformer can operation again.
10.Repair and Maintain
To maintain the transformer operation well, should make repaire and maintaince.
10.1 Generally, in dry place, clearn it one time every year or mor long time. If others place if have dust or chemisty air inside, should check every 3 month or 6 month.
10.2 When check, if find collect dust, should clearn them to keep the air ventilation and prevent insulated attack.special clearn the insulated terminal of transformer,the mat of desk,and keep the dry compress air(2-5 dry air) to clean the dust
10.3 Check the fix firmware,join piece whether start, conductor whether have rust,corrosive trial,also check whether have climp electric and carbon trial on the insulated surface.Should take relative action to solve if need.
10.4 Load regulate voltage transformer should consider the resistant of load tap switch to judge the transformer whether can operation, no need make the rest test.
10.5 After several year operation( Suggest 5 years),to do the resulated resist test to judge the transformer whether can operation, no need make the rest test.
10.6 After Dry-type transformer inspection, should meet the (Electric transformer repaire rule) DL/T573 and the electric device anti-test rule.
11.Repair and Maintain
11.1 When transformer operantion, should make safe barrier around transformer, to prevent accident.
11.2 When transformer operantion,Warning to touch the main part of transformer to prevent accident.
11.2 The test of transformer,install, repaire should be done by qualification worker.
