Distribution Transformer Guide
Kev faib tawm transformer yog ib qho tseem ceeb ntawm cov hluav taws xob hluav taws xob. Nws lub luag haujlwm tseem ceeb yog txhawm rau txo qis qhov hluav taws xob los ntawm qib kis mus rau theem kev faib tawm, ua rau nws tsim nyog rau kev siv hauv tsev thiab kev lag luam. Lub tshuab hluav taws xob faib hluav taws xob tau teeb tsa ze ntawm cov neeg siv khoom siv, feem ntau ntawm tus ncej lossis hauv av, muab cov kauj ruam kawg hauv qhov hluav taws xob ua ntej nws nkag mus rau hauv lub tsev.
Cov transformers no tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab lub zog muaj peev xwm, xws li los ntawm ob peb kVA mus rau ntau MVA. Kev xaiv ntawm lub tshuab hloov pauv yog nyob ntawm qhov xav tau ntawm cov khoom thauj thiab cov qib voltage xav tau los ntawm cov neeg siv khoom. Lawv kuj tau tsim los tiv thaiv qhov hnyav sab nraum zoov thiab muab kev lag luam txhim khu kev qha nyob rau lub sijhawm ntev.
Kev faib tawm transformer muaj ntau yam tseem ceeb, nrog rau cov tub ntxhais, windings, tank, thiab rwb thaiv tsev. Cov tub ntxhais yog ua los ntawm qib high-qib silicon steel laminations uas txo cov tub ntxhais poob thiab muab kev ua tau zoo. Cov windings muaj cov tooj liab lossis txhuas hlau qhwv ib ncig ntawm lub hauv paus, uas tau txais thiab xa cov hluav taws xob hluav taws xob rau cov neeg siv khoom. Lub tank transformer yog ua los ntawm cov ntawv hlau thiab muab kev tiv thaiv rau cov tub ntxhais thiab windings. Cov txheej txheem rwb thaiv tsev muab rwb thaiv tsev ntawm cov windings thiab lub tank los tiv thaiv hluav taws xob tawm thiab ua kom muaj kev nyab xeeb.
Tsis tas li ntawd, kev faib cov transformers tuaj yeem muab faib ua ntau hom raws li lawv qhov kev tsim thiab kev siv. Tus ncej-mounted transformer yog mounted rau ntawm ib tug ncej los yog cross-arm thiab yog tsuas yog siv rau tsawg voltage tis. Pad-mounted transformers, ntawm qhov tod tes, muab tso rau ntawm lub pob zeb ua pob zeb thiab tsim nyog rau thaj chaw hauv nroog uas qhov chaw muaj tsawg. Substation transformers yog tsim los rau kev faib hluav taws xob siab thiab tau nruab rau sab nraum zoov thiab sab hauv tsev substations. Thaum kawg, cov cam khwb cia resin transformer yog siv nyob rau hauv qhov kev ua tau zoo thiab cov qauv kev nyab xeeb yuav tsum tau ua.
Hauv kev xaus, faib transformers ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob rau cov neeg siv khoom. Lawv tau tsim los nrog kev ua haujlwm ntev thiab kev ntseeg siab hauv lub siab, thiab yog tsim los ntawm ntau yam tseem ceeb uas ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Nrog rau ntau hom transformers muaj, txhua tus nrog lawv tus kheej tsim tshwj xeeb thiab daim ntawv thov, nws yog ib qho tseem ceeb uas yuav tau xaiv txoj cai rau ib daim ntawv thov tshwj xeeb los xyuas kom meej kev ua tau zoo thiab kev nyab xeeb.
