Kev txiav txim siab yog tias lub tshuab hloov pauv tsis zoo yuav tsum muaj kev ntsuam xyuas ntawm nws qhov kev ua tau zoo thiab qhov xwm txheej. Nov yog ob peb qhov taw qhia thiab cov kauj ruam uas koj tuaj yeem ua los ntsuas seb lub transformer puas yog:
Kev tshuaj xyuas qhov muag:
Tshawb xyuas lub transformer rau ib qho kev puas tsuaj ntawm lub cev, xws li tawg, tawg, hluav taws kub rwb thaiv tsev, lossis cov cim qhia ntawm overheating. Kev puas tsuaj rau lub cev yuav qhia tau tias muaj kev puas tsuaj sab hauv lossis kev puas tsuaj ntawm lub cev.
Kev ntsuas nrog Multimeter:
Ua cov kev ntsuam xyuas yooj yim siv ib lub multimeter los xyuas qhov kev tiv thaiv ntawm thawj thiab theem nrab windings. Kev nyeem ntawv tsis zoo, xws li qhib circuits lossis luv circuits, yuav qhia tau tias muaj qhov tsis raug.
Tshawb xyuas qhov txuas ntxiv ntawm qhov pib thiab theem nrab windings. Yuav tsum tsis muaj kev txuas ntxiv, vim tias cov windings yuav tsum tau muab hluav taws xob cais tawm ntawm ib leeg.
Insulation Resistance Test (Megger Test):
Ua ib qho kev ntsuas kev tiv thaiv hluav taws xob siv Megger lossis cov ntsuas hluav taws xob tiv thaiv hluav taws xob. Qhov kev ntsuas no ntsuas qhov kev tiv thaiv ntawm cov rwb thaiv tsev ntawm cov windings thiab cov tub ntxhais transformer. Tsawg rwb thaiv tsev nyeem ntawv yuav qhia tau tias rwb thaiv tsev puas los yog ya raws ingress.
Load Test:
Txuas lub thauj khoom mus rau theem nrab winding thiab ntsuas qhov tso zis voltage nyob rau hauv cov xwm txheej load. Cov zis hluav taws xob txawv txav, qhov hloov pauv ntawm qhov hluav taws xob, lossis tsis muaj peev xwm muab qhov yuav tsum tau muaj peev xwm yuav qhia tau tias qhov hloov pauv tsis raug.
Kev soj ntsuam pom ntawm Roj-Immersed Transformers:
Rau cov roj-immersed transformers, tshuaj xyuas cov roj kom tsis muaj xim, muaj kab mob, lossis cov ntxhiab tsw txawv txawv, uas yuav qhia tau tias muaj kev puas tsuaj los yog kev puas tsuaj sab hauv.
Diagnostic Tests:
Rau kev ntsuam xyuas ntau dua, xav txog kev kuaj mob tshwj xeeb xws li kev ntsuas hluav taws xob, kev tshuaj ntsuam xyuas roj (DGA), lossis cheb cov lus teb zaus (SFRA). Cov kev ntsuam xyuas no tuaj yeem muab cov ncauj lus kom ntxaws txog qhov xwm txheej ntawm lub tshuab hloov hluav taws xob thiab kuaj xyuas qhov tsis raug lossis qhov txawv txav.
Kev soj ntsuam thiab cov ntaub ntawv keeb kwm:
Tshawb xyuas cov ntaub ntawv keeb kwm kev ua tau zoo thiab cov ntaub ntawv khaws cia ntawm lub transformer. Cov teeb meem tsis tu ncua, tsis ua haujlwm tsis tu ncua, lossis kev ua haujlwm poob qis dhau sijhawm tuaj yeem qhia txog teeb meem hauv qab.
Kev sab laj nrog cov kws tshaj lij:
Yog tias koj tsis paub meej txog qhov xwm txheej ntawm lub tshuab hloov pauv lossis yog tias koj xav tias muaj teeb meem tseem ceeb, xav txog kev sab laj nrog cov kws tsim khoom tsim nyog lossis cov kws tshaj lij tshwj xeeb hauv kev tshuaj ntsuam xyuas thiab kev sim ntawm transformer. Lawv tuaj yeem ua cov kev ntsuam xyuas ntxaws thiab pom zoo ua kom tsim nyog raws li lawv qhov kev tshawb pom.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev kuaj xyuas qhov tsis zoo ntawm cov transformer yuav tsum muaj kev txawj ntse thiab cov cuab yeej tshwj xeeb, tshwj xeeb tshaj yog rau kev kuaj mob siab dua. Yog tias koj xav tias lub tshuab hloov pauv tsis raug lossis tsis ua haujlwm, nws raug nquahu kom nrhiav kev pab los ntawm cov kws tshaj lij los xyuas kom meej qhov kev ntsuam xyuas thiab kev ntsuas tsim nyog.
