Qhuav hom transformer: cia siab rau cua convection kom txias, feem ntau yog siv rau hauv zos teeb pom kev zoo, hluav taws xob circuits. Transformers xws li tshuab thiab khoom siv, nyob rau hauv lub hwj chim system, dav dav chav turbine transformers, boiler transformers, tshauv tshem tawm transformers, plua plav tshem tawm transformers, desulfurization transformers, thiab lwm yam. yog qhuav-hom transformers, nrog ib tug conversion ratio ntawm 6000V / 400V thiab 10KV / 400V, uas yog siv rau loads nrog ntsuas voltage ntawm 380V. Yuav kom muab tso rau nws yooj yim, ib tug qhuav-hom transformer yog hais txog ib tug transformer uas nws core thiab windings tsis impregnated nyob rau hauv insulating roj.
Piv nrog cov roj-hom transformers, qhuav-hom transformers tsis muaj hluav taws kub, tawg, muaj kuab paug thiab lwm yam teeb meem vim tsis muaj roj, yog li cov hluav taws xob specifications thiab cov kev cai tsis xav kom qhuav-hom transformers yuav tsum tau muab tso rau hauv ib tug nyias muaj nyias ib chav tsev. Tshwj xeeb tshaj yog nyob rau hauv cov tshiab series, qhov poob thiab suab nrov tau raug txo mus rau ib theem tshiab, thiab cov xwm txheej tau tsim rau lub transformer thiab lub vijtsam low-voltage muab tso rau hauv tib chav faib khoom.
1. Kub tswj qhov system ntawm qhuav-hom transformer
Kev ua haujlwm thiab kev pabcuam lub neej ntawm cov tshuab ziab khaub ncaws qhuav feem ntau yog nyob ntawm qhov kev ntseeg tau ntawm cov transformer winding rwb thaiv tsev. Lub rwb thaiv tsev puas los ntawm qhov cua kub tshaj qhov rwb thaiv tsev tiv thaiv qhov kub thiab txias, uas yog ib qho ntawm cov laj thawj tseem ceeb rau lub tshuab hluav taws xob tsis ua hauj lwm ib txwm, yog li nws tseem ceeb heev uas yuav tsum tau saib xyuas qhov ntsuas kub ntawm lub transformer thiab nws lub tswb tswj.
2. Kev tiv thaiv hom qhuav-hom transformer
Raws li cov yam ntxwv ntawm kev siv ib puag ncig thiab kev tiv thaiv kev tiv thaiv, lub tshuab ziab khaub ncaws tuaj yeem xaiv cov plhaub sib txawv. IP23 tiv thaiv lub plhaub feem ntau yog xaiv, uas tuaj yeem tiv thaiv cov khoom txawv teb chaws uas muaj txoj kab uas hla ntau dua 12 hli thiab cov tsiaj me xws li nas, nab, miv, thiab finches los ntawm kev nkag mus, ua rau muaj qhov tsis zoo xws li luv luv Circuit Court thiab lub zog tsis ua haujlwm, thiab muab kev tiv thaiv. rau qhov live. Yog tias lub tshuab hluav taws xob yuav tsum tau muab tso rau sab nraum zoov, siv IP23 tiv thaiv enclosure, uas tuaj yeem tiv thaiv dej los ntawm lub kaum sab xis ntawm 60 degree mus rau txoj kab ntsug ntxiv rau IP20 tiv thaiv cov yam ntxwv tau hais los saum toj no. Txawm li cas los xij, IP23 enclosure yuav txo qis lub peev xwm txias ntawm transformer, thiab kev saib xyuas yuav tsum tau them rau qhov txo qis ntawm nws lub peev xwm ua haujlwm thaum xaiv.
3. Txias txoj kev ntawm qhuav-hom transformer
Qhuav hom transformer txias txoj kev muab faib ua cua txias (AN) thiab yuam cua txias (AF). Thaum ib txwm cua-txias, lub transformer tuaj yeem ua haujlwm tsis tu ncua ntev ntawm lub peev xwm ntsuas. Thaum yuam cua txias, cov zis muaj peev xwm ntawm transformer tuaj yeem nce 50%. Nws yog qhov tsim nyog rau kev ua haujlwm tsis sib xws, lossis kev ua haujlwm overload thaum muaj xwm txheej ceev, vim tias qhov poob thiab impedance voltage nce siab heev thaum lub sij hawm overload, nws yog nyob rau hauv lub xeev uas tsis yog-economic kev khiav hauj lwm, yog li nws yuav tsum tsis txhob nyob rau hauv lub sij hawm ntev mus tas li overload.
4. Lub peev xwm dhau ntawm lub tshuab ziab khaub ncaws qhuav
Lub peev xwm ntawm lub tshuab ziab khaub ncaws qhuav yog cuam tshuam nrog qhov kub thiab txias, qhov teeb meem ntawm kev thauj khoom ua ntej overload (pib load), rwb thaiv tsev thiab kub dissipation ntawm lub transformer thiab lub sij hawm cua sov tsis tu ncua, thiab lwm yam, yog tias tsim nyog, lub overload nkhaus. ntawm qhuav-hom transformer tuaj yeem tau txais los ntawm cov chaw tsim khoom. Tam sim no, cov khoom tsim tawm txhua xyoo ntawm cov khoom siv hluav taws xob ziab khaub ncaws hauv Suav teb tau mus txog 10,000MVA, ua rau nws yog ib lub tebchaws uas muaj ntau tshaj plaws thiab muag khoom ntawm cov tshuab ziab khaub ncaws qhuav hauv ntiaj teb. Nrog rau qhov nrov thiab daim ntawv thov ntawm SC (B) 9 series nrog lub suab nrov tsawg (lub suab nrov ntawm cov khoom siv hluav taws xob hauv qab 2500kVA tau tswj tsis pub dhau 50dB) thiab kev txuag hluav taws xob (tsis muaj qhov poob qis los ntawm 25%), qhov ntsuas kev ua tau zoo thiab kev tsim khoom siv tshuab. ntawm qhuav-hom transformers nyob rau hauv Tuam Tshoj tau mus txog lub ntiaj teb no qib siab. Nrog rau kev nrov nrov thiab kev siv cov tshuab ziab khaub ncaws qhuav, nws cov cuab yeej tsim khoom kuj tau ua tiav zoo, thiab nws tuaj yeem kwv yees tias yav tom ntej cov tshuab ziab khaub ncaws qhuav yuav tsim ntxiv hauv cov hauv qab no.
Lub peev xwm ntawm lub tshuab ziab khaub ncaws qhuav yog cuam tshuam nrog qhov kub thiab txias, qhov teeb meem ntawm kev thauj khoom ua ntej overload (pib load), rwb thaiv tsev thiab kub dissipation ntawm lub transformer thiab lub sij hawm cua sov tsis tu ncua, thiab lwm yam, yog tias tsim nyog, lub overload nkhaus. ntawm qhuav-hom transformer tuaj yeem tau txais los ntawm cov chaw tsim khoom.
Yuav ua li cas siv nws lub peev xwm overload? Tus kws sau ntawv tso ob lub ntsiab lus rau kev siv:
(1) Thaum xaiv los xam lub peev xwm transformer, nws tuaj yeem raug txo kom tsim nyog: tag nrho xav txog qhov muaj feem cuam tshuam rau lub sij hawm luv luv ntawm qee cov hlau dov, vuam thiab lwm yam khoom siv - sim siv lub zog dhau ntawm lub tshuab ziab khaub ncaws. txo lub peev xwm transformer;
(2) Nws tuaj yeem txo qhov peev xwm los yog tus naj npawb ntawm cov chav nyob: hauv qee qhov chaw, qhov kev sib txuas ntawm cov khoom siv hluav taws xob yuav tsum siab dua, kom cov transformer muaj peev xwm thiab tus naj npawb ntawm cov transformers xaiv los ntawm qhov project loj. Lub peev xwm dhau ntawm lub tshuab hluav taws xob qhuav tuaj yeem compressed thaum xav txog nws lub peev xwm cia, thiab nws tuaj yeem txo qis thaum txiav txim siab ntawm cov chav nyob. Thaum lub transformer nyob rau hauv overloading, ua tib zoo saib xyuas nws cov kev khiav hauj lwm kub: yog hais tias qhov kub nce mus rau 155 degree (ib lub tswb yog muab), load txo kev ntsuas (tso rau ib co lwm yam loads) yuav tsum tau coj mus rau lub hwj chim mov mus rau lub ntsiab. thauj khoom.
