Ua rau Distribution Transformer Failure
Distribution transformers ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob los ntawm cov chaw tsim hluav taws xob mus rau tsev neeg thiab kev lag luam. Cov transformers no hloov hluav taws xob siab rau hauv hluav taws xob tsis tshua muaj hluav taws xob, ua kom muaj kev nyab xeeb rau cov neeg siv khoom siv. Txawm li cas los xij, kev faib hluav taws xob hloov pauv tsis ua haujlwm tuaj yeem ua rau poob nyiaj txiag tseem ceeb thiab, qee zaum, muaj kev phom sij rau lub neej. Hauv tsab xov xwm no, peb tham txog cov laj thawj ntawm kev xa tawm transformer tsis ua haujlwm.
1. Ntau dhau
Ib qho ntawm feem ntau ua rau kev faib khoom transformer tsis ua haujlwm yog overloading. Thaum lub transformer yog overloaded, cov tam sim no ntau dhau los ntawm nws cov khoom yuav ua rau lawv overheat, ua rau rwb thaiv tsev puas thiab tsis ua hauj lwm. Overloading tuaj yeem tshwm sim los ntawm kev xav tau ntau dhau los ntawm cov neeg siv khoom, kev hloov pauv tsis zoo, lossis kev hloov pauv tsis ua haujlwm.
2. Hluav taws xob
Hluav taws xob surges yog tam sim no voltage spikes uas tuaj yeem tshwm sim hauv daim phiaj hluav taws xob vim yog xob laim, khoom siv tsis raug, lossis lwm yam. Cov surges no tuaj yeem ua rau cov transformers puas tsuaj los ntawm kev puas tsuaj los ntawm kev rwb thaiv tsev thiab sab hauv arcing. Cov hluav taws xob surges kuj tuaj yeem ua rau lub tshuab hluav taws xob windings rau luv luv, ua rau muaj kev puas tsuaj loj.
3. Kev rwb thaiv tsev tsis ua haujlwm
Rwb thaiv tsev yog ib qho tseem ceeb ntawm transformers vim nws tiv thaiv hluav taws xob hluav taws xob los ntawm kev khiav mus rau hauv ib puag ncig. Yog hais tias lub rwb thaiv tsev nyob rau hauv ib tug transformer tsis ua hauj lwm vim muaj hnub nyoog, overheating, los yog lub cev puas tsuaj, lub transformer yuav poob loj heev. Rwb thaiv tsev tsis ua hauj lwm kuj tuaj yeem tshwm sim los ntawm ingress ntawm noo noo vim faulty seals los yog gaskets nyob rau hauv lub transformer.
4. Transformer Aging
Transformers muaj lub neej ntev, thiab tom qab siv qee lub sijhawm, lawv yuav ua tsis tiav. Tus nqi ntawm kev laus nyob ntawm ntau yam, nrog rau kev ua haujlwm, kev saib xyuas, thiab ib puag ncig. Transformers uas tsis tau tswj xyuas kom txaus lossis ua haujlwm hauv cov xwm txheej hnyav tuaj yeem ua tsis tiav vim kev laus.
5. Cov xwm txheej ib puag ncig
Ib puag ncig yam xws li kub, av noo, thiab corrosive yam yuav ua rau transformer tsis ua hauj lwm. Cov xwm txheej huab cua hnyav xws li dej nyab thiab cua daj cua dub tuaj yeem ua rau cov hloov pauv puas. Transformers ntsia rau hauv cov cheeb tsam uas muaj dej nyab lossis huab cua hnyav yuav tsum muaj kev tiv thaiv tshwj xeeb thiab kev saib xyuas kom tsis txhob ua tsis tiav.
Hauv kev xaus, kev faib hluav taws xob tsis ua haujlwm tuaj yeem cuam tshuam cov khoom siv hluav taws xob, ua rau kev poob nyiaj txiag, thiab ua rau muaj kev nyab xeeb. Nws yog ib qho tseem ceeb los txheeb xyuas qhov ua rau tsis ua haujlwm thiab siv kev tiv thaiv kom tsis txhob ua tsis tiav. Kev saib xyuas zoo li kev kuaj xyuas tsis tu ncua, tu, thiab hloov roj tuaj yeem txuas ntxiv lub neej ntawm cov tshuab hloov pauv, tiv thaiv kev thauj khoom ntau dhau, thiab kuaj pom kev laus thiab kev rwb thaiv tsev tsis ua haujlwm ntxov. Tsis tas li ntawd, transformers raug rau ib puag ncig hnyav yuav tsum muaj kev tiv thaiv zoo thiab tswj kom tsis txhob ua tsis tiav.
