01 General
1.1 Project Background
5000 kVA uapeb theem ncoo mounted transformertau xa mus rau Asmeskas xyoo 2025. Lub zog ntsuas hluav taws xob ntawm lub tshuab hluav taws xob yog 5000 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 33GrdY / 19.053kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.48Y / 0.277kV, lawv tsim ib pawg vector ntawm YNyn0.
Peb lub-theem ncoo-mounted transformer yog ib qho khoom siv hluav taws xob hloov hluav taws xob uas siv dav hauv kev faib khoom hauv nroog thiab nyob deb nroog. Nws lub luag haujlwm tseem ceeb yog hloov siab - hluav taws xob hluav taws xob mus rau qis- hluav taws xob hluav taws xob, ua kom muaj kev nyab xeeb rau kev lag luam, kev lag luam, thiab cov neeg siv nyob hauv. Lub ncoo mount transformers muaj lub kaw stainless hlau tank tsim los tiv thaiv ntau yam kev nyab xeeb. Lub thawv muaj lub tshuab hloov pauv, hloov khoom siv, khoom siv tiv thaiv, thiab lwm yam khoom siv hluav taws xob tsim nyog. Tus qauv tsim ntawm peb -theem ncoo-mounted transformer suav nrog ntau yam kev nyab xeeb, suav nrog kev tiv thaiv overload, luv- tiv thaiv Circuit Court, thiab av hauv av kom muaj kev nyab xeeb thiab kev saib xyuas. Qhov no 5000 kVA peb-theem ncoo- mounted transformer, nruab nrog plaub- txoj haujlwm thauj khoom, sib txuas lub zog muaj peev xwm nrog kev tswj hwm kev thauj khoom yooj yim, muab cov neeg siv nrog kev nyab xeeb, ruaj khov, thiab siv hluav taws xob zoo.
Vim lub transformer muaj peev xwm loj heev, tus qauv bayonet fuses muaj nyob rau hauv kev ua lag luam tsis haum rau nws kev tiv thaiv. Qhov kev sib tw no tau hais txog tag nrho los ntawm peb cov qauv tsim sab hauv: windings ntxiv dag zog nrog cov txheej txheem ua kom muaj zog thiab cov txheej txheem txias txias ua kom nws muaj peev xwm tiv taus siab inrush thiab txhaum tam sim no; ua ke nrog siab -impedance tsim thiab kev sib koom ua ke ntawm kev soj ntsuam ntse, cov kev txawv txav sab hauv tau raug tshem tawm zoo thiab ua ntej- ceeb toom. Yog li ntawd, lub transformer tau ua tiav siab ntev thiab ntev - lub sijhawm ua haujlwm txhim khu kev qha yam tsis muaj kev cia siab rau kev tiv thaiv fuse sab nraud.

02 Kev tsim khoom
2.1 transformer bushing
Hluav taws xob cables ua qhov txuas ntawm qis-voltage pad mount transformers bushings thiab ntau yam hluav taws xob loads: rau sib dua-load scenarios, ib lub cable txuas rau txhua bushing feem ntau yog txaus los ua kom tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob. Txawm li cas los xij, thaum cuam tshuam nrog ntau dua - cov khoom siv thauj khoom lossis cov tshuab, ntau lub cables yuav tsum tau txuas nrog tib lub bushing.
Cov no tsawg-voltage bushings tuaj ua ntej-nrog rau ntau lub qhov txuas, uas yog tsim tshwj xeeb los txhawb kev sib txuas ntawm ntau- cables. Qhov tseem ceeb, tus naj npawb ntawm qhov muab rau txhua qhov qis -voltage bushing feem ntau txiav txim siab los ntawm qhov loj thiab qhov tshwj xeeb ntawm cov padmount transformer sib xws.
2.2 oil level gage
Cov roj qib ntsuas ntsuas yog ib qho tseem ceeb pom iav, feem ntau mounted rau sab ntawm lub tank, muab qhov pom tseeb pom ntawm cov insulating kua ntim. Featuring qhov kub thiab txias -them nyiaj npib, nws tso cai rau kev saib xyuas kom tseeb kom ntseeg tau tias cov roj qib tseem nyob hauv qhov kev ua haujlwm nyab xeeb, uas yog qhov tseem ceeb rau kev rwb thaiv tsev kom zoo, cua txias, thiab ntev - lub sij hawm cia siab ntawm lub transformer.
2.3 Tank
Cov roj tank yog ua los ntawm cov hlau thiab kho nrog cov tshuaj tiv thaiv -corrosive coatings los txhim kho nws cov oxidation thiab corrosion, ncua nws cov kev pab cuam lub neej. Kev tsim cov roj tank tiv thaiv cov dej noo thiab plua plav nkag, tiv thaiv cov roj insulating zoo thiab tiv thaiv nws qhov kev puas tsuaj. Cov roj insulating hauv lub tank muaj cov khoom siv hluav taws xob zoo heev, tiv thaiv hluav taws xob luv luv thiab cov teeb meem to, yog li tiv thaiv cov transformer cov khoom tseem ceeb.
2.4 kais changer
Qhov tsis muaj -load kais hloov pauv (NLTC) ntawm lub ncoo mounted transformer yog ib qho tseem ceeb ntawm kev tswj hluav taws xob nyob rau sab siab -voltage. Ua haujlwm tsuas yog thaum lub tshuab hloov pauv yog de-energized, nws hloov pauv ntawm cov kais dej sib txawv kom them nyiaj rau daim phiaj hluav taws xob sib txawv thiab cov kev xav tau sib tw, kom ntseeg tau tias cov zis hluav taws xob ruaj khov. Compact nyob rau hauv cov qauv, nws yog tag nrho yoog mus rau lub ncoo mounted transformer lub sab nraum zoov ua hauj lwm scenario.
03 Kev Xeem
Kev Ntsuas Kev Ntsuas Siab (High Voltage Test):- Siv cov hluav taws xob siab rau ntau qhov chaw ntawm lub tshuab hluav taws xob (xws li windings thiab lub casing, ntawm qhov sib txawv windings, thiab lwm yam) los ua qhov kev sim siab. Lub hom phiaj yog los xyuas seb lub transformer puas muaj peev xwm tswj tau nws cov rwb thaiv tsev kev ua tau zoo nyob rau hauv hluav taws xob load tej yam kev mob.
- Muaj ob hom kev ntsuas kev ntsuas siab: DC tiv taus qhov ntsuas hluav taws xob thiab AC tiv thaiv qhov ntsuas hluav taws xob. DC tiv thaiv qhov ntsuas hluav taws xob feem ntau yog siv los txheeb xyuas qhov polarity thiab lub zog ntawm rwb thaiv tsev, thaum AC tiv thaiv qhov ntsuas hluav taws xob feem ntau yog siv los simulate hluav taws xob kev ntxhov siab ntawm lub tshuab hluav taws xob hauv kev ua haujlwm tiag tiag.
04 Packing thiab Shipping
05 Site thiab Summary
Ua ntej, lub pob zeb pedestal yog ua ntej- nrum kom haum rau chav tsev qhov ntev thiab thauj khoom-cov kabmob specs, nrog rau ua ntej- cov channel tshwj xeeb rau txoj kab txuas mus. Tom ntej no, lub transformer yog lifted rau hauv txoj hauj lwm siv cov khoom siv hoisting tsim nyog (nrog rau kev ua tib zoo saib xyuas kom sib npaug thaum nqa), tom qab ntawd ruaj ruaj rau lub pedestal nrog fastening bolts.
Tom qab ntawd, high-voltage thiab low-voltage cables txuas nrog rau lawv cov terminals siab heev-txhua qhov kev sib txuas tau nruj kom zoo, thiab kev tiv thaiv rwb thaiv tsev raug txheeb xyuas kom ua tau raws li cov qauv kev nyab xeeb. Tom qab xaim, ib qho kev kuaj xyuas sab hauv yog ua tiav: lees paub qhov hloov pauv ntawm qhov raug (kev nyab xeeb) txoj haujlwm, tshuaj xyuas qhov nruj ntawm cov hlua txuas, thiab ua kom ntseeg tau tias ua tau -hauv meters / cov khoom tsis zoo.
Thaum kawg, kev tshuaj xyuas ua ntej - kev tshuaj xyuas kev nyab xeeb yog ua tiav txhawm rau tshem tawm cov kev phom sij, thiab tom qab ntawd lub tshuab hloov pauv tau npaj rau thawj zaug kev debugging.
