01 General
1.1 Project Description
500 kVA peb theem ncoo mounted transformer tau xa mus rau Tebchaws Meskas hauv xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 500 kVA nrog KNAN txias. Qhov siab voltage yog 12.47GrdY / 7.2 kV nrog ± 2 * 2.5% tapping ntau (NLTC), qhov tsawg voltage yog 0.48Y / 0.277 kV, lawv tsim ib pawg vector ntawm YNyn0.
Lub davhlau ya nyob twg no -hom, peb-theem, tsib-limb pad-mounted transformer yog engineered rau superior kev ntseeg tau thiab kev ua tau zoo nyob rau hauv xav tau kev faib hluav taws xob daim ntawv thov. Tsim los nrog siab - qhov ntsuas tam sim no ntawm 600A nyob rau sab siab -voltage, nws ua kom muaj zog xa hluav taws xob thiab kev ruaj ntseg network.
Lub hauv paus ntawm nws txoj kev tsim kho nta siab - zoo tooj liab windings rau kev pom kev zoo thiab kev ua haujlwm zoo, muab tso rau hauv hwm FR3® kua. Qhov no advanced, biodegradable dielectric roj muab tshwj xeeb hluav taws kev nyab xeeb, txhim khu kev ruaj ntseg ntev, thiab superior thermal tswj piv rau cov roj ntxhia ib txwm muaj.
Lub hom phiaj tseem ceeb ntawm kev tsim qauv yog kev ua haujlwm ruaj ntseg thiab kev tiv thaiv. Ob qhov siab -voltage thiab low-voltage cores yog nruab nrog grounded electrostatic shields, zoo txo qhov kev pheej hmoo ntawm kev hloov hluav taws xob tsis zoo thiab ua kom muaj lub zog huv, ruaj khov.
Rau kev saib xyuas tas mus li thiab kev ruaj ntseg ua haujlwm, lub tshuab hloov pauv tau nruab nrog cov txheej txheem kev ntsuas ntsuas: ntsuas qib ua kua, ntsuas qhov ntsuas cua kub, thiab lub tshuab nqus tsev / ntsuas ntsuas. Lub tshuab nqus tsev / qhov ntsuas siab tau txuas ntxiv nrog cov neeg sib txuas lus kom muab lub sijhawm tiag tiag - lub tswb nrov rau cov xwm txheej tseem ceeb, ua kom muaj kev saib xyuas zoo thiab kev tiv thaiv lub cev.
Kev sib xyaw cov khoom siv ruaj khov, cov thev naus laus zis tshiab, cov yam ntxwv ntawm kev nyab xeeb, thiab cov cuab yeej siv dav dav, lub ncoo no -mounted transformer muab qhov kev cia siab, nyab xeeb, thiab ntev ntev - kev daws teeb meem rau cov khoom siv hauv av niaj hnub no.

02 Kev tsim khoom
2.1 Core
Lub hauv paus ntawm lub transformer mounting pads yog tsim los ntawm qib siab - qib, qis- poob hluav taws xob steel laminations, precisely stacked thiab securely clamped los ua ib tug robust peb-theem, tsib-limb magnetic circuit. Critically, ib qho hluav taws xob tiv thaiv hauv av-feem ntau yog cov ntawv ci tooj liab- yog muab tso rau hauv nruab nrab ntawm cov tub ntxhais thiab qhov qis -voltage windings. Cov ntaub thaiv npog no yog ruaj khov rau lub transformer hauv av davhlau ya nyob twg, tsim ib txoj hauv kev rau lub ntiaj teb. Nws lub luag haujlwm tseem ceeb yog ua kom muaj peev xwm hloov tau siab- zaus zaus hloov hluav taws xob thiab ntau- hom suab nrov deb ntawm cov windings, yog li tiv thaiv rwb thaiv tsev, txo cov hluav taws xob kev ntxhov siab, thiab txo qis kev nthuav tawm ntawm electromagnetic cuam tshuam rau hauv qhov kev faib khoom thib ob.
2.2 Radial Pub
Lub transformer mounting pads nyob rau hauv lub davhlau ya nyob twg radial feed configuration ua hauj lwm pab raws li qhov kawg tis taw tes nyob rau hauv ib tug radial zog network, tau txais lub hwj chim los ntawm ib tug upstream qhov chaw. Nws cov thawj terminals txuas ncaj qha mus rau lub hauv paus feeder, nce voltage rau downstream loads ntawm lwm yam outputs. Raws li lub davhlau ya nyob twg, nws tau txais txiaj ntsig ntawm qhov radial system ib zaug -point dependency: ib qho kev cuam tshuam los yog qhov hluav taws xob yuav cuam tshuam lub hwj chim rau lub transformer thiab tag nrho cov txuas txuas mus txog thaum qhov teeb meem raug daws. Nws compact, hauv av-mounted tsim ua kom ntseeg tau, siv tau hluav taws xob faib rau qhov kawg- cov neeg siv daim ntawv thov.
2.3 FR3 yog '
Lub ncoo-mounted transformer yog ntim nrog FR3® dielectric kua, tus hwm, hluav taws kub- tiv taus ntuj ester roj tau los ntawm cov roj zaub. Nws raug cais raws li "Less Flammable" kua (ib ASTM D6871) nrog qhov hluav taws kub siab tshaj 360 degree, txhim khu kev nyab xeeb hauv thaj chaw muaj neeg lossis ib puag ncig. Tshaj li nws qhov kev nyab xeeb hluav taws zoo tshaj plaws, FR3® muab cov txiaj ntsig zoo ib puag ncig vim nws yooj yim biodegradable, tsis yog - tshuaj lom, thiab muaj cov pa roj carbon tsawg. Los ntawm kev pom kev ua tau zoo, nws qhov kev ua tau zoo ntawm cov dej noo zoo thiab kev ruaj khov siab ua kom ntev lub neej ntawm cellulose rwb thaiv tsev, yog li ua rau lub tshuab hluav taws xob muaj peev xwm dhau, ncua kev laus, thiab ua rau lub neej ua haujlwm ntev dua nrog txo kev siv sijhawm ntev -cov kev xav tau tu.
2.4 Gaug
Lub ncoo-mounted transformer yog nruab nrog cov khoom siv dav dav ntawm cov ntsuas ntsuas thiab ntsuas ntsuas kev ua haujlwm tsis tu ncua thiab kev tiv thaiv. Lub ntsuas ntsuas ua kua ua kom pom tseeb qhov pom ntawm lub dielectric kua ntim rau kev saib xyuas. Ib tug dial - hom roj ntsuas kub ntsuas (WTI) saib xyuas qhov tseem ceeb saum toj kawg nkaus - roj kub los ntsuas thermal load. Lub kaw lus siab yog saib xyuas los ntawm lub tshuab nqus tsev / qhov ntsuas qhov siab, qhia ob qho tib si sub- atmospheric thiab zoo sab hauv siab. Qhov tseem ceeb, qhov ntsuas siab no yog haum nrog kho tau hermetically kaw hluav taws xob tiv tauj. Cov kev sib cuag no tuaj yeem raug teeb tsa kom qhib lub tswb nyob deb lossis pib tswj cov kab ke thaum tshawb pom ntawm preset siab -siab lossis siab- lub tshuab nqus tsev, hloov qhov taw qhia yooj yim rau hauv cov khoom siv ntawm lub tshuab hluav taws xob tiv thaiv. Ua ke, cov cuab yeej no muab cov neeg ua haujlwm nrog cov ntaub ntawv tseem ceeb tiag tiag - sijhawm thiab kev ceeb toom kev nyab xeeb.
2.4 Tus txiv neej qhov 20 "nrog ntsuas phoo
Lub transformer yog nruab nrog ib tug 20-inch manhole ruaj los ntawm ib lub xauv xauv. Qhov kev nkag tau qhib, kaw nrog lub gasket ruaj khov, muab cov neeg ua haujlwm tso cai nrog qhov chaw nyab xeeb thiab nyab xeeb ntawm kev nkag mus rau sab hauv, kev saib xyuas, thiab kev sim. Lub ntsuas phoo ua haujlwm tseem ceeb ntawm kev nyab xeeb thiab kev nyab xeeb, tiv thaiv kev nkag mus rau cov khoom nyob tsis tau thiab ua kom muaj kev ncaj ncees ntawm lub kaw lus kaw, roj puv.
2.5 HV / LV av
Lub ncoo-mounted transformer nta ib qho kev qhia dav thiab muaj zog hauv av rau ob qho tib si nws qhov siab -voltage (HV) thiab qis-voltage (LV) Cheebtsam. Qhov kev nyab xeeb tseem ceeb no suav nrog HV electrostatic winding shield, LV winding shield, thiab transformer core nws tus kheej -tag nrho cov txuas mus tas li rau lub tsheb npav hauv av. Lub tsheb npav no txuas nrog kev ruaj ntseg ntawm -impedance qis, bolted txuas mus rau sab nraud hauv av. Los ntawm kev tsim qhov no ib leeg, txhim khu kev qha lub ntiaj teb siv taw tes, lub kaw lus ua kom muaj kev nyab xeeb ntawm kev ua txhaum tam sim no, kev ua haujlwm xau, thiab qhov hloov pauv hluav taws xob. Qhov kev tsim qauv no ua rau muaj kev ruaj ntseg hluav taws xob zoo, tiv thaiv cov neeg ua haujlwm, tiv thaiv cov khoom siv, thiab txhim kho tag nrho cov khoom siv hluav taws xob sib raug zoo (EMC) kev ua haujlwm ntawm kev teeb tsa.
03 Kev Xeem
Pad-mounted transformer tank kev ntsuam xyuas suav nrog cov kev ntsuam xyuas tseem ceeb los xyuas kom meej cov qauv kev ncaj ncees, kev sib khi ua haujlwm, thiab kev sib raug zoo nrog cov roj insulating, ua raws li cov qauv zoo li ANSI C57.12.28, ANSI C57.12.00, thiab GB 50148-2010. Cov kev ntsuam xyuas no suav nrog kev ntsuas siab qhov twg lub tank yuav tsum tiv taus qhov tsawg kawg nkaus ntawm 15 psig yam tsis muaj roj to lossis cov khoom tshem tawm, thiab tiv taus 7 psi yam tsis muaj kev cuam tshuam mus tas li; lub tshuab nqus tsev deformation nrog rau kev siv -67 kPa lub tshuab nqus tsev, ntsuas qhov deformation ntawm 10 lub ntsiab lus tseem ceeb (piv txwv li, lub tank phab ntsa, lub hau, cov khoom siv ntxiv) ua ntej thiab tom qab lub tshuab nqus tsev tso tawm los xyuas seb qhov deformation tsawg kawg nkaus (feem ntau yog 0.01–0.03 hli); thiab cov kev ntsuam xyuas xau-los ntawm kev nias lub taub hau lub taub hau (tom qab tshem tawm lub siab nyem valve) los yog saib xyuas kev hloov siab, vim tias tsis muaj qhov zoo / qhov tsis zoo siab tuaj yeem qhia tau tias gasket los yog seam leaks. Tsis tas li ntawd, cov roj insulating nyob rau hauv lub tank raug kuaj rau lub zog dielectric, cov ntsiab lus noo noo, thiab cov roj yaj (ib ASTM D3487) kom ntseeg tau tias nws txhawb nqa hluav taws xob rwb thaiv tsev thiab lub tank ruaj khov, nrog kev kuaj xyuas tom qab kuaj xyuas tsis muaj kev puas tsuaj rau lub tank, cov ntsaws ruaj ruaj tsis zoo, thiab ua raws li cov kev txwv deformation kom paub meej tias muaj kev nyab xeeb sab nraum zoov.
