Fais fab Transformer Box: Lub hom phiaj, Cheebtsam, hom, thiab kev nyab xeeb
Ibhluav taws xob transformer boxyog ib tug tawv, hlau enclosure uas tsev lub transformer. Nws txoj haujlwm yog qhov yooj yim heev tab sis tseem ceeb heev: nwssiv ntau dua -voltage hluav taws xob los ntawm daim phiajthiabnce nws mus rau qis dua voltageuas tsev thiab lag luam tuaj yeem siv tau (feem ntau120/240Vhauv thaj chaw nyob).
Covlub thawv ntsuabkoj pom ntawm cov nyom, ze ntawm txoj kev taug kev, lossis ntawm txoj kev ces kaum tsis yog rau qhov zoo xwb. Lawv pab khaws cianeeg thiab tsiajnyob deb ntawmtxaus ntshai heev voltage, thaum tseem tiv thaiv cov cuab yeej los ntawm huab cua thiab kev ntxhov siab txhua hnub.
Dab tsi yog Electric Transformer Box Ua
Voltage txo (lub luag haujlwm tseem ceeb)
Thaum kawg ntawm lub hnub, lub thawv transformer lub hom phiaj yog tag nrhoqis siab - faib voltagesmus rau theem uas muaj kev nyab xeeb thiab siv tau rau cov khoom siv hauv tsev.
Kev tiv thaiv kev nyab xeeb (xauv vim li cas)
Vim tias cov khoom siv hluav taws xob sab hauv tuaj yeem nyob, chav tsev yogxauv, insulated, thiab grounded. Lub casing hlau ntawd zoo li qhov thaiv ntawm cov pej xeem thiab cov khoom siv hluav taws xob txaus ntshai.
Huab cua tiv thaiv (los nag tshwm sim)
Sab nraum zoov transformer thawv yog tsim los lisnag, cua, thiab khib nyiab. Thaum lawv ua haujlwm kom raug, lawv pab ua kom lub zog ntws tsis tu ncua.
Kev ntseeg tau zoo dua nrog lub zog hauv av
Hauv ntau qhov chaw, transformer thawv txhawbunderground hluav taws xob faib, uas feem ntau txhais tau tiastsawg tawmtshaj cov kab saum toj kawg nkaus-tsawg raug cua, ntoo, thiab cua daj cua dub tsoo tej yam nyob ib puag ncig.
Common Cheebtsam nyob rau hauv (los yog txuas rau) ib tug Transformer Box
Txhua qhov kev teeb tsa transformer yog txawv me ntsis, tab sis feem ntau muaj cov khoom tseem ceeb zoo sib xws.
1. Core Cheebtsam (qhov "active" part)
Core:Ua los ntawm stacked, laminated steel los xij (feem ntau silicon steel). Nws tsim ib txoj hauv kev qis - tsis txaus siab rau cov hlau nplaum sib nqus, yog li lub zog tuaj yeem hloov pauv tau zoo ntawm cov windings.
Windings (thawj thiab theem nrab):Coils ntawm insulatedtooj liab los yog aluminiumhlau. Covthawj windingsiv nyob rau hauv high voltage, thiab lubtheem nrab windingxa tawm qhov hluav taws xob qis dua koj siv.
Insulating roj:Cov roj ntxhia nyob ib puag ncig ntawm cov tub ntxhais thiab windings. Nws pab nrogrwb thaiv tsevthiab thiabnqa cua sov musyog li kub tsis tau tawm ntawm tes.
2. Cov khoom siv tiv thaiv thiab kev nyab xeeb
fuses / fuse txuas:Cov no tiv thaiv lub transformer los ntawmovercurrent thiab luv circuits. Yog tias muaj qee yam tsis raug, lawv tuaj yeem "tshuab" thiab kaw cov khoom kom tsis txhob muaj kev puas tsuaj loj dua.
Surge / xob laim ntes:Cov no pab tiv thaiv lub kaw lus los ntawm qhov hluav taws xob nce siab - xob laim yog qhov piv txwv classic- los ntawm kev hloov hluav taws xob ntau dhau mus rau hauv av.
Cov cuab yeej siv siab (PRD):Yog tias muaj kev ua txhaum sab hauv ua rau muaj kev phom sij txaus ntshai, cov cuab yeej no pab daws nws kom lub tank tsis tawg lossis tawg.
Buchholz relay (ntawm chav tsev loj):Gas -kev soj ntsuam kev nyab xeeb relay uas tuaj yeem hnov qhov tsis raug sab hauv (xws li kev tsim cov pa roj). Nws tuaj yeem ua rau lub tswb lossis cov cuab yeej tiv thaiv kev mus ncig.
Lockable steel qhov rooj:Lub thawv nws tus kheej yog ib feem ntawm qhov kev nyab xeeb - khaws cov khoom muaj zog tiv thaiv thiab ruaj ntseg.
3. Kev sib txuas hluav taws xob
Bushings:Porcelain los yog polymer insulators uas cia cov conductors hla hauv av hauv av kom zoo, pab tiv thaiv arcing.
Load break switch:Siv kom cov kws tshaj lij tuaj yeem cais cov transformertxawm nyob rau hauv load, ua kom muaj kev ruaj ntseg.
Coj mus rhaub changer:Kho lub transformer cov zis los ntawm kev hloov ntau npaum li cas tig lub windings siv. Qhov no yuav pab ua kom muaj hluav taws xob ruaj khov thaum muaj xwm txheej hloov pauv.
4. Txias thiab saib xyuas
Cua txias radiators/tubes:Cov no ua rau thaj tsam saum npoo los pab dissipate tshav kub ntawm cov roj.
Silica gel breather:Ua kom cov cua tuaj qhuav (qhib yog xov xwm phem rau rwb thaiv tsev).
Roj theem taw qhia / pom iav:Cia cov kws tshaj lij xyuas tias cov roj qib yog qhov tseeb.
Qhov ntsuas kub (WTI / OTI):Ntsuas cov roj thiab cov cua kub cua sov kom pom cov cua sov thaum ntxov.
5. Compartmentalization (lub thawv ntim li cas)
Ntau lub thawv- hom transformers tau muab faib ua cov khoom, xws li:
High-voltage (HV) qhov chaw:Feem ntau suav nrog HV fuses, thauj khoom - tawg keyboards, thiab bushings.
Tsawg-voltage (LV) compartment:Feem ntau muaj LV terminals, ntsuas, thiab cov cuab yeej tiv thaiv.
Transformer tank:Lub hauv paus kaw ntu tuav cov roj- rau hauv cov tub ntxhais thiab cov coils.
Hom Transformer Boxes
Pad-mounted transformers
Cov no yogtamper- pov thawj, compartmentalized hlau thawvntsia raupob zeb pob zeb. Koj yuav pom lawv nyob hauv thaj chaw nyob, tsev kawm ntawv, thiab thaj chaw lag luam, thiab lawv feem ntau txuas mus rauunderground kab.
Ib zaug -theem:Feem ntau ntsuab thiab duab plaub, pab pawg me nyiam2–3 lub tsev.
Peb theem -:Cov chav loj dua siv qhov xav tau ntau dua, xws li chaw lag luam lossis chaw lag luam.
Ncej-mounted transformers (tus "tau" style)
Cov no yog cov cylindrical units mounted rau cov khoom siv hluav taws xob-ib qho chaw nyob deb nroog lossis qhov chaw uas tseem sivoverhead zog kab. Lawv feem ntau yooj yim dua thiab pheej yig dua rau nruab rau saum huab cua.
Underground/vault transformers
Rau qhov ntom ntom, qhov chaw - txwv, lossis siab - kev nyab xeeb hauv nroog ib puag ncig, cov tshuab hloov pauv tuaj yeem raug teeb tsa hauv av hauv tsev vaults. Cov no yog tsim los ua kom ruaj thiab txhim khu kev qha nyob rau hauv subterranean tej yam kev mob.
Kev faib tawm los ntawm Kev Ua Haujlwm thiab Kev Tsim Kho
Compact substation / box-hom transformer substation
Kev teeb tsa ua ntej -fabricated uas ua kesiab-voltage switchgear, transformer, thiab low-voltage khoomnyob rau hauv ib chav tsev compact-feem ntau mus- mus rau lub nroog faib.
Qhuav -hom transformer box
Hloov roj, nws sivcua los yog khoom resinrau cua txias thiab rwb thaiv tsev. Nws yog feem ntau xaiv raukev siv sab hauv tsevthiab cov chaw xws li tsev kho mob lossis ib puag ncig uas muaj roj muaj kev txhawj xeeb.
Roj-immersed transformer thawv
Sivntxhia rojrau rwb thaiv tsev thiab cua txias, ua rau nws zoo haum rausiab dua - zog sab nraum zoovdaim ntawv thov thiab ntau qhov chaw lag luam.
Cov ntsiab lus tseem ceeb Koj yuav hnov txog hauv ib lub thawv
Transformer tub ntxhais(qhov voltage- hloov qhov)
Switchgear & fuses(kev tiv thaiv txhaum cai thiab cais tawm)
Tuag- kev txiav tawm pem hauv ntej(feem ntau nyob rau hauv ncoo- mounted units, pab kom tsis txhob raug energized qhov chaw nkag tau)
Installation Considerations (Tsis txhob hla qhov no)
Kev teeb tsa kom raug tsis yog xaiv tau yog tias koj xav tau kev nyab xeeb thiab ua haujlwm ntev -. Qhov loj yog:
Qhov chaw raug:Cia chav txaus rau kev tu thiab qhov cua. Tsis tas li ntawd zam tej qhov chaw uas cov dej tuaj yeem sau tau ntawm cov ntsaws ruaj ruaj.
Foundation thiab mounting:Kev ruaj ntseg mounting tiv thaiv kev nyuaj ntawm cov cables thiab kev sib txuas.
Cable routing:Kho cov qog thiab lim ntshav pab tiv thaiv kev nkag mus rau hauv dej thiab kev puas tsuaj rau lub cev.
Grounding:Kev cog qoob loo yuav tsum ua kom tau raws li qhov yuav tsum tau ua thiab raug txheeb xyuas thaum ua haujlwm.
Huab cua sealing:Qhov rooj gaskets thiab cable nkag ntsaws ruaj ruaj yuav tsum tau ua kom zoo thiab txhim kho kom zoo.
Cov Lus Qhia Txog Kev Nyab Xeeb (Tshaj -ceev faj)
Ua haujlwm ze ntawm lub thawv transformer muajhigh voltage. Yog li txoj cai nyab xeeb yog yooj yim: yog tias koj tsis tau kawm / tso cai, tsis txhob kov nws.
Tsuas yog cov kws tshaj lij hluav taws xob tsim nyog lossis cov kws tshaj lij hluav taws xob yuav tsum tau pab lawv.
Tsis txhob qhib qhov rooj tshwj tsis yog tias koj tau kawm thiab tso cai.
Khaws thaj chaw kom huv si -tshwj xeeb nyob ib puag ncig lub ncoo- mounted units.
Ua tib zoo saib cov ntawv ceeb toom, cov cai kaw tawm / tagout, thiab cov txheej txheem ntawm qhov chaw.
Yog koj pomhlawv tsw ntxhiab, buzzing, pa taws, los yog puas rwb thaiv tsev, hu rau lub chaw siv hluav taws xob lossis tus kws tshaj lij muaj ntawv tso cai tam sim ntawd.
Kev kho thiab tshuaj xyuas
Transformer thawv feem ntau xav tau kev tshuaj xyuas niaj hnub, xws li:
Tshawb xyuas qhov rooj, xauv, ntsaws ruaj ruaj, thiab kho vajtse
Txheeb xyuas grounding continuity
Nrhiav cov cim ntawm dej ingress los yog corrosion ntawm cable nkag
Xyuas kom muaj qhov qhib qhov cua (yog tias muaj) tsis thaiv
Ua kom cov ntawv ceeb toom pom pom thiab tsis puas
Nyob ntawm hom transformer thiab qhov tseem ceeb npaum li cas, cov khoom siv hluav taws xob kuj tseem ua tau yam zoo liroj ua piv txwv, ntsuas kub, thiab lwm yam kev kuaj mob.
