Distribution Transformer Test Procedure
Distribution transformers ua lub luag haujlwm tseem ceeb hauv kev muab lub zog rau cov neeg siv khoom nyob thiab kev lag luam. Txhawm rau kom ntseeg tau tias cov tshuab hloov pauv no ua haujlwm ntawm qhov ua tau zoo tshaj plaws, nws yog ib qho tseem ceeb uas yuav tsum tau ua cov txheej txheem kev sim thiab tu. Nyob rau hauv tsab xov xwm no, peb yuav piav qhia txog cov txheej txheem kev sib tw transformer feem ntau.
1. Kev tshuaj xyuas qhov muag
Thawj kauj ruam hauv kev sim cov khoom siv hluav taws xob faib hluav taws xob yog kev soj ntsuam pom. Nws suav nrog kev tshuaj xyuas lub tshuab hluav taws xob sab nrauv rau txhua qhov kev puas tsuaj ntawm lub cev, xws li dents, khawb lossis xeb. Tsis tas li ntawd, lub transformer lub nameplate raug tshuaj xyuas los xyuas nws cov ntaub ntawv, nrog rau kev ntsuam xyuas, serial tooj, chaw tsim tshuaj paus thiab hnub tsim khoom.
2. Transformer Turns Ratio Test
Kev ntsuas qhov ntsuas qhov sib npaug yog ua los txiav txim siab seb lub tshuab hloov pauv puas ua haujlwm raug thiab nyob rau hauv cov qauv tsim. Qhov kev ntsuam xyuas no ntsuas qhov piv ntawm thawj thiab theem nrab winding lem thiab xyuas kom meej tias lawv phim lub transformer qhov ntsuas.
3. Rwb thaiv tsev Resistance Test
Rwb thaiv tsev yog ib qho tseem ceeb hauv kev ua haujlwm ntawm transformer. Qhov Kev Ntsuas Hluav Taws Xob Hluav Taws Xob ntsuas qhov kev tiv thaiv ntawm lub rwb thaiv tsev kom ntseeg tau tias nws tsis muaj kev cuam tshuam los yog deteriorating. Qhov kev sim no pab tiv thaiv kom tsis txhob muaj hluav taws xob tawg lossis hluav taws xob tsis ua haujlwm.
4. Kev kuaj roj
Lub transformer roj yog ib qho tseem ceeb insulating thiab txias nruab nrab. Roj Sampling kuaj qhov zoo thiab qhov xwm txheej ntawm cov roj, ntxiv rau txhua yam kab mob uas nws muaj. Qhov kev kuaj no tuaj yeem kuaj xyuas txhua yam teeb meem uas yuav ua rau kev laus ntxov ntxov lossis tsis ua haujlwm ntawm lub tshuab hloov pauv.
5. Kev Ntsuas Hluav Taws Xob
Qhov Kev Ntsuas Hluav Taws Xob ntsuas lub zog uas tau tawg hauv lub tshuab hluav taws xob hluav taws xob rwb thaiv tsev. Qhov kev ntsuam xyuas no ua kom ntseeg tau tias lub tshuab hluav taws xob rwb thaiv tsev tsis raug cuam tshuam rau txhua txoj hauv kev thiab tuaj yeem tiv taus qhov ntsuas hluav taws xob thiab zaus.
6. Kev Ntsuam Xyuas Cov Hluav Taws Xob
Dissolved Gas Analysis (DGA) yog cov cuab yeej kuaj mob uas kuaj pom muaj cov pa phem lossis cov pa phem hauv cov roj hloov pauv. Ib qho kev txawv txav ntawm cov pa roj los yog kev hloov pauv hauv cov pa roj tuaj yeem qhia tau tias muaj teeb meem hauv lub tshuab hluav taws xob rwb thaiv tsev.
Hauv kev xaus, kev ntsuam xyuas tsis tu ncua thiab kev saib xyuas ntawm cov khoom xa tawm yog qhov tseem ceeb los tswj lawv cov kev ua tau zoo, kev ntseeg tau, thiab kev ua haujlwm ntev. Txhua qhov kev ntsuam xyuas saum toj no ua lub luag haujlwm tseem ceeb hauv kev ua kom lub tshuab hloov pauv ua haujlwm zoo. Yog tias muaj teeb meem raug kuaj pom thaum kuaj, lawv yuav tsum tau hais kom sai, kom tsis txhob muaj qhov ua tsis tiav.
