Xaiv txoj cai transformer yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam ncaj qha rau lub zog hluav taws xob qhov kev ntseeg siab, kev lag luam kev lag luam, thiab kev nyab xeeb ntev -. Ib qhov zoo- xaiv transformer nteg lub hauv paus ruaj khov rau ib qhov project, qhov kev xaiv tsis raug tuaj yeem ua rau muaj hluav taws xob tsis tu ncua, nce nqi kho, thiab txawm tias ua haujlwm tsis tiav. Lub hauv paus ntawm kev xaiv tsis yog tsuas yog hais txog kev sib piv cov ntsiab lus, tab sis nrhiav qhov zoo tshaj qhov sib npaug ntawm cov kev ua tau zoo, kev nqis peev pib, ntev - cov nqi khiav lag luam, thiab ntawm - qhov chaw nyob.
Thawj kauj ruam yog ua qhov kev txheeb xyuas qhov tseeb thiab kev txiav txim siab muaj peev xwm. Thaum xam qhov yuav tsum tau muaj peev xwm transformer, nws yog ib qho tseem ceeb rau lub hauv paus rau ob qho tib si uas twb muaj lawm thiab foreseeable yav tom ntej tag nrho load zog. Cov ntsiab lus tseem ceeb uas yuav tsum xav txog suav nrog cov khoom siv hluav taws xob, cov yam ntxwv ntawm kev ua haujlwm (xws li kev thauj khoom tas mus li lossis cuam tshuam sib cuam tshuam), thiab tus nqi tsim nyog. Lub hauv paus ntsiab lus lees paub yog tias kev tswj hwm lub tshuab hloov lub sijhawm ntev - lub sijhawm ua haujlwm thauj khoom ntawm ib puag ncig 60% mus rau 70% ntawm nws cov peev txheej feem ntau muaj qhov ua tau zoo tshaj plaws thiab kev lag luam sib npaug. Ib tug undersized transformer yuav ua rau ntev overload, shortening nws lifespan. Piv txwv li, ib qho kev hloov pauv loj yuav ua haujlwm nyob rau hauv lub teeb lub teeb rau lub sijhawm ntev, ua rau muaj feem ntau ntawm tsis muaj -load poob, txo kev ua haujlwm, thiab cov nqi hluav taws xob tsis tsim nyog.
Thaum lub peev xwm yooj yim tau txiav txim siab, cov kauj ruam tom ntej yog xaiv hom kev hloov pauv uas tsim nyog raws li kev teeb tsa ib puag ncig thiab cov ntawv thov. Tam sim no, kua-immersed transformers thiab qhuav- hom transformers yog ob pawg loj. Cov kua ua kua-immersed transformers muaj qhov zoo xws li cov cua kub zoo dua, tus nqi qis dua, thiab muaj zog tshaj qhov muaj peev xwm. Lawv tsim nyog rau cov chaw ua haujlwm sab nraum zoov lossis chav hloov pauv ywj pheej uas qhov chaw txaus. Txawm li cas los xij, lawv cov roj insulating nthuav tawm qhov teeb meem hluav taws kub, xav tau kev tiv thaiv hluav taws ntxiv. Qhuav- hom transformers, tshwj xeeb tshaj yog cob- hom cam khwb cia, yog cov yam ntxwv los ntawm kev ua roj -dawb, nplaim taws- retardant, thiab yuav tsum tau saib xyuas tsawg heev. Cov yam ntxwv no ua rau lawv xaiv rau qhov chaw nyob sab hauv tsev uas yuav tsum muaj kev nyab xeeb siab, xws li cov chaw thauj khoom hauv siab -cov tsev nce siab, subways, cov ntaub ntawv chaw, tsev kho mob, thiab cov chaw lag luam. Tsis tas li ntawd, rau cov ntawv thov tshwj xeeb, cov hom tshwj xeeb yuav tsum raug xaiv: ntawm -load kais- hloov pauv hloov pauv rau cov kev xav tau ntawm cov hluav taws xob nquag, cov hloov hluav taws xob hloov hluav taws xob rau cov tshuab hluav taws xob rectifier, thiab cov khoom siv hluav taws xob tshwj xeeb rau cov chaw nres tsheb photovoltaic uas yuav tsum tiv taus DC kev tsis ncaj ncees thiab cov ntsiab lus siab sib haum xeeb.
Kev siv hluav taws xob hluav taws xob yog qhov tseem ceeb ntawm kev lag luam thiab kev lag luam hauv kev xaiv niaj hnub transformer uas tsis tuaj yeem raug saib xyuas. Ib qho kev poob tag nrho ntawm transformer muaj tsis muaj -load poob (core poob) thiab load poob (tooj liab poob). Cov khoom lag luam ntsib cov chav kawm ua haujlwm tau zoo dua qub (xws li Tuam Tshoj Lub Zog Label Chav Kawm 1 lossis Chav Kawm 2) yuav tsum tau ua ntej. Txawm hais tias siab - transformers ua tau zoo yuav muaj tus nqi pib ntawm 10% mus rau 30% siab dua, lawv cov kev poob qis heev txhais tau hais tias kev txuag ntawm cov nqi hluav taws xob nyob rau ob peb xyoos ntawm kev ua haujlwm tuaj yeem them tus nqi pib. Kev soj ntsuam tus nqi ntawm lub neej yog qhov tseem ceeb tshwj xeeb rau cov haujlwm uas txhua xyoo ua haujlwm tshaj 4,000 teev. Qhov kev tshuaj ntsuam no suav nrog kev nqis peev thawj zaug, tus nqi ntawm lub zog poob, thiab cov nqi kho mob, muab cov duab tseeb ntawm tag nrho cov nqi ntawm cov tswv cuab ntawm lub transformer lub neej kev pab cuam.
Tshaj li cov ntsiab lus tseem ceeb no, cov txheej txheem xaiv yuav tsum ua tib zoo xav txog ntau yam ncauj lus kom ntxaws. Hais txog kev hloov pauv ib puag ncig, kev txiav txim siab yog qhov tsim nyog rau qhov siab - qhov chaw siab tshaj, txhim kho kev tiv thaiv- kev txhim kho corrosion yog xav tau rau thaj chaw ntub dej lossis ntug hiav txwv, thiab cov suab nrov yuav tsum tau teev rau cov suab nrov - qhov chaw rhiab heev. Rau kev tiv thaiv kev teeb tsa, kev tiv thaiv relay tsim nyog (xws li kev tiv thaiv kev sib txawv thiab kev tiv thaiv overcurrent) thiab kev tiv thaiv lub cev (xws li cov cuab yeej siv siab thiab cov roj relays) yuav tsum tau teeb tsa raws li qhov tseem ceeb ntawm transformer. Kuj tseem muaj qhov hloov pauv loj zuj zus mus rau kev sib koom ua ke ntse hauv online saib xyuas cov cuab yeej los taug qab lub transformer tiag tiag - lub sijhawm noj qab haus huv. Thaum kawg, nws yog ib qho tseem ceeb rau kev ntsuam xyuas tus neeg muag khoom qhov kev tsim nyog, cov ntaub ntawv teev tseg, kev tsim khoom muaj peev xwm, thiab tom qab- kev muag khoom kev txhawb nqa kom ntseeg tau cov khoom lag luam thiab kev txhawb nqa kev pabcuam txuas ntxiv.
Hauv cov ntsiab lus, kev xaiv qhov hloov pauv tau zoo yog qhov kev txiav txim siab zoo- ua cov txheej txheem. Nws xav kom cov engineers tsis yog tsuas yog paub txog cov txheej txheem kev ua haujlwm nkaus xwb tab sis kuj tseem nkag siab tob txog cov xwm txheej ntawm daim ntawv thov, cov yam ntxwv thauj khoom, thiab lub sijhawm ntev - lub hom phiaj ua haujlwm. Los ntawm kev suav cov khoom hnyav, kev sib piv ntawm kev tshawb fawb, hauv - qhov tob ntawm kev txheeb xyuas tus nqi ntawm lub neej, thiab kev saib xyuas kom meej, ib tus tuaj yeem xaiv "lub plawv ntawm lub zog" uas yuav ua haujlwm ruaj khov, ua tau zoo, thiab kev lag luam rau ntau xyoo tom ntej.
