Distribution Transformer Failure
Distribution transformers ua lub luag haujlwm tseem ceeb hauv kev faib hluav taws xob. Lawv nqis los ntawm qhov hluav taws xob los ntawm qib sib kis mus rau theem kev faib khoom, yog li muab lub zog rau cov tsev, kev lag luam thiab kev lag luam. Txawm li cas los xij, transformer tsis ua haujlwm tuaj yeem ua rau muaj hluav taws xob tsis zoo thiab ua rau muaj kev cuam tshuam loj thiab poob nyiaj txiag. Kab lus no yog tsom los tham txog cov laj thawj ntawm kev faib khoom transformer tsis ua haujlwm.
Overloading: Overloading yog ib qho ntawm cov ua rau kev faib khoom transformer tsis ua haujlwm. Thaum lub load ntawm lub transformer tshaj lub peev xwm, nws ua rau kub heev uas yuav ua rau rwb thaiv tsev puas thiab puas rau lub transformer windings. Qhov no tuaj yeem ua rau tsis ua haujlwm xws li tawg thiab hluav taws kub.
Hnub nyoog: Kev faib cov transformers muaj lub neej ntev, thiab thaum lawv loj hlob tuaj, qhov kev pheej hmoo ntawm kev ua tsis tiav yuav nce ntxiv. Cov khoom siv rwb thaiv tsev siv rau hauv cov khoom siv hluav taws xob tuaj yeem deteriorate nyob rau lub sijhawm vim muaj ntau yam xws li kub, noo noo, thiab tshuaj lom neeg raug. Qhov no tuaj yeem ua rau muaj teeb meem xws li luv luv Circuit Court, arcing, thiab rwb thaiv tsev tsis ua haujlwm.
Environmental yam: Transformers nyob rau hauv ib puag ncig hnyav, xws li thaj chaw uas muaj av noo siab, huab cua ntsev, thiab qhov siab siab, yog qhov cuam tshuam rau kev ua tsis tiav vim ib puag ncig. Cov dej noo tuaj yeem nkag mus rau hauv lub transformer, ua rau txo cov rwb thaiv tsev tiv thaiv, luv luv Circuit Court, thiab corrosion ntawm hluav taws xob sib txuas.
xob laim ntaus thiab surges: Transformers tseem muaj kev cuam tshuam rau xob laim thiab surges tshwm sim los ntawm lub hwj chim surges thiab voltage spikes. Cov xwm txheej no tuaj yeem ua rau muaj qhov siab ntawm cov dej ntws tam sim no, ua rau muaj kev puas tsuaj los ntawm cov rwb thaiv tsev thiab winding puas.
Kev saib xyuas tsis zoo: Tsis muaj kev saib xyuas kom zoo yog qhov tseem ceeb rau kev hloov pauv tsis ua haujlwm. Kev laus thiab ib puag ncig muaj peev xwm ua rau muaj kev puas tsuaj rau rwb thaiv tsev, uas tuaj yeem cuam tshuam los ntawm kev saib xyuas tsis zoo xws li kev tu tsis zoo, tsis muaj kev sim roj, thiab cov cua txias tsis zoo.
Hauv kev xaus, kev faib khoom hloov pauv tsis ua haujlwm cuam tshuam rau kev ua neej nyob ntawm tib neeg, kev lag luam, thiab tag nrho cov zej zog. Qhov ua rau ntawm transformer tsis ua hauj lwm tau raug txheeb xyuas tias yog overloading, kev laus, ib puag ncig yam tseem ceeb, xob laim thiab hluav taws xob surges, thiab kev saib xyuas tsis zoo. Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob zoo thiab tiv thaiv qhov tsis ua haujlwm ntawm lub tshuab hluav taws xob, kev saib xyuas tsis tu ncua thiab kev teeb tsa zoo yog qhov tseem ceeb.
