Distribution Transformer Failure Analysis
Lub tshuab hluav taws xob faib hluav taws xob yog ib qho tseem ceeb ntawm cov kab hluav taws xob hluav taws xob. Nws yog lub luag haujlwm rau kev nce qib ntawm cov kab hluav taws xob hluav taws xob siab mus rau theem tsim nyog rau kev faib rau cov tsev thiab cov lag luam. Hmoov tsis zoo, cov transformers no feem ntau ua tsis tiav vim muaj ntau yam laj thawj, xws li kev thauj mus los ntau dhau mus rau ib puag ncig. Hauv tsab xov xwm no, peb yuav tshawb txog qee qhov laj thawj ntawm kev faib tawm transformer tsis ua haujlwm.
Ib qho ntawm cov laj thawj tseem ceeb ntawm kev faib khoom transformer tsis ua haujlwm yog overload. Qhov no tshwm sim thaum lub transformer raug rau ib tug ntau ntawm tam sim no. Kev thauj khoom ntau dhau tuaj yeem tshwm sim los ntawm ntau yam, suav nrog kev thov kom muaj zog ntxiv, kev saib xyuas tsis zoo, lossis cov khoom tsis raug. Overloading tuaj yeem ua rau cov rwb thaiv tsev nyob rau hauv lub transformer tawg, uas tuaj yeem ua rau luv luv Circuit Court thiab thaum kawg transformer tsis ua hauj lwm.
Environmental yam tseem tuaj yeem ua rau kev hloov pauv tsis ua haujlwm. Corrosion thiab noo noo tuaj yeem ua rau kev puas tsuaj rau lub rwb thaiv tsev transformer, ua rau luv luv Circuit Court. Qhov kub thiab txias tuaj yeem ua rau cov roj transformer tawg lossis nthuav dav, uas tuaj yeem ua rau cov rwb thaiv tsev puas thiab ua rau tsis ua haujlwm. xob laim ntaus thiab lwm yam hluav taws xob surges kuj ua rau cov transformers puas.
Hnub nyoog yog lwm yam uas ua rau kev hloov pauv tsis ua haujlwm. Raws li lub hnub nyoog transformers, lawv cov rwb thaiv tsev tawg, lawv cov khoom hnav tawm, thiab lawv cov kev ua tau zoo txo qis, ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov transformers uas tau tshaj lawv lub neej kev cia siab, uas feem ntau nyob ib ncig ntawm 30 xyoo.
Kev saib xyuas tsis zoo yog lwm qhov tseem ceeb uas ua rau muaj kev hloov pauv tsis ua haujlwm. Kev saib xyuas tsis tu ncua, xws li kev sim roj thiab ntsuas cua sov, tuaj yeem txheeb xyuas cov teeb meem uas yuav tshwm sim ua ntej lawv dhau los ua kev puas tsuaj loj. Kev ua haujlwm tsis tu ncua tuaj yeem ua rau muaj teeb meem me me kom nce ntxiv, ua rau muaj teeb meem loj dua hauv txoj kev.
Txhawm rau tiv thaiv kev xa tawm tsis ua haujlwm, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li kev saib xyuas zoo thiab hloov cov hloov pauv uas tau tshaj lawv lub neej kev cia siab. Transformer manufacturers kuj tau pib koom nrog cov thev naus laus zis siab, xws li kev saib xyuas lub sijhawm tiag tiag thiab kev kuaj mob, rau hauv lawv cov khoom los muab kev tshawb pom ntxov ntawm cov teeb meem tshwm sim.
Hauv kev xaus, kev faib hluav taws xob tsis ua haujlwm tuaj yeem ua rau muaj kev cuam tshuam loj rau daim phiaj hluav taws xob thiab ua rau ntau lab daus las hauv kev puas tsuaj. Overload, ib puag ncig yam, hnub nyoog, thiab kev saib xyuas tsis zoo yog ib qho ntawm cov laj thawj tseem ceeb ntawm kev hloov pauv tsis ua haujlwm. Kev saib xyuas zoo, kev sim tsis tu ncua, thiab kev siv cov thev naus laus zis siab heev tuaj yeem pab tiv thaiv kev hloov pauv tsis ua haujlwm thiab ua kom muaj kev ntseeg siab ntawm cov phiaj xwm hluav taws xob.
