Ib feem Discharge (PD) nyob rau hauv transformers yog hais txog ib qho tshwm sim uas lub zos dielectric tawg tshwm sim nyob rau hauv ib feem me me ntawm lub rwb thaiv tsev system nyob rau hauv high voltage kev nyuaj siab. Cov kev tso tawm no tsis txuas rau cov electrodes tab sis tsuas yog tshwm sim hauv thaj chaw ntawm cov rwb thaiv tsev tsis muaj zog. PD feem ntau tsis muaj zog thiab tsis tuaj yeem kuaj pom los ntawm tib neeg lub siab, xav tau cov cuab yeej tshwj xeeb ntsuas.
Ua rau ib nrab tso tawm hauv Transformers
Qhov ua rau ntawm ib nrab tso tawm hauv transformers yog multifaceted, encompassing ob peb yam:
1. Cov khoom siv rwb thaiv tsev thiab cov qauv:
Qhov tsis xws luag xws li npuas, impurities, thiab tawg: Cov teeb meem no cuam tshuam qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob, ua rau ib nrab tso tawm.
Tsawg dielectric qhov tsis tu ncua ntawm npuas: Cov npuas ua rau lub zog hluav taws xob ntau dua piv rau cov khoom siv rwb thaiv tsev uas nyob ib sab, ua rau lawv muaj kev cuam tshuam ntau dua rau kev tawg thiab tawm.
Tsis tsim nyog rwb thaiv tsev qauv tsim: Ntau interlayer los yog tig teb lub zog nyob rau hauv qhuav-hom transformers vim tsis zoo tsim yuav ua rau ib nrab paug.
Ntse ntug thiab burrs: Insulating thiab metallic Cheebtsam nrog cov npoo ntse lossis burrs tuaj yeem ua rau lub zog hluav taws xob hauv zos, ua rau muaj qhov paug tawm.
2. Cov yam ntxwv ua haujlwm:
Lub sijhawm ua haujlwm ntev thiab thauj khoom hloov pauv: Cov yam tseem ceeb no ua rau kev laus thiab hnav ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob, txo lawv cov khoom insulating thiab ua rau ib nrab tawm.
Overvoltage: Overvoltage nyob rau hauv lub hwj chim system, tshwm sim los ntawm lwm yam tseem ceeb (xws li xob laim) los yog lwm yam sab hauv (xws li switching hauj lwm), muaj peev xwm tshaj lub breakdown voltage ntawm cov ntaub ntawv, ua rau ib nrab paug.
3. Kev teeb tsa thiab txheej txheem txheej txheem:
Cov txheej txheem tsim khoom tsis txaus: Kev tswj lub tshuab nqus tsev tsis zoo thaum ziab, lub sij hawm ziab tsis txaus, thiab qhov kub thiab txias tuaj yeem tso cov roj seem hauv cov coils.
Kev puas tsuaj: Rwb thaiv tsev yuav raug puas tsuaj thaum lub sij hawm installation, los yog lub sij hawm tsis ua hauj lwm ntev yuav ua rau kom cov dej noo nyob rau hauv cov ntaub ntawv rwb thaiv tsev, cuam tshuam rau theem paug.
Cov txheej txheem winding thiab sib dhos tsis raug: Cov teeb meem xws li burrs ntawm qhov siab thiab tsis tshua muaj hluav taws xob coj los yog qhov kev ncua deb tsis zoo thaum lub sij hawm sib dhos tuaj yeem cuam tshuam rau qee qhov kev tso tawm.
Kev phom sij ntawm kev tso tawm ib nrab
Txawm hais tias ib nrab tso tawm hauv transformers yog nyob hauv zos thiab tsis muaj zog, nws ua rau muaj kev phom sij ntev, feem ntau los ntawm kev puas tsuaj rau cov ntaub ntawv rwb thaiv tsev:
1.Direct kev puas tsuaj rau rwb thaiv tsev: Nruam ib nrab tso tawm maj mam erodes lub rwb thaiv tsev, muaj peev xwm ua kom tiav kev tawg raws sij hawm. Cov teebmeem electrochemical tsim cov roj reactive xws li ozone thiab nitric oxide, ntxiv corroding lub rwb thaiv tsev.
2. Cov cua sov hauv zos: Ib nrab tso tawm ua kom sov, uas tuaj yeem ua rau qhov kub thiab txias ntawm dielectric, txawm tias ua rau carbonization.
Kev Tshawb Fawb Txog Kev Tso Tawm Ib Feem
Kev tshawb nrhiav txoj hauv kev rau kev tso tawm ib nrab feem ntau suav nrog cov tshuab hluav taws xob, ultrasonic, thiab tshuaj lom neeg:
1. Kev siv hluav taws xob: Siv oscilloscopes, ib feem tso zis detectors, los yog xov tooj cua cuam tshuam meters los soj ntsuam cov pa tawm waveforms los yog xov tooj cua cuam tshuam theem.
2. Cov txheej txheem Ultrasonic: Tshawb xyuas cov nthwv dej ultrasonic tsim los ntawm kev tawm thiab hloov cov nthwv dej no rau hauv hluav taws xob teeb liab rau kev tsom xam.
3. Cov txheej txheem tshuaj: Kev tshuaj xyuas cov ntsiab lus thiab cov qauv sib txawv ntawm ntau cov roj yaj hauv cov roj, feem ntau hu ua "chromatographic tsom xam."
Kev Tiv Thaiv Kev Tiv Thaiv rau Kev Tso Tawm Ib Feem
Txhawm rau kom tsis txhob muaj kev phom sij ntawm kev tso tawm ib nrab, ntau yam kev tiv thaiv tuaj yeem ua tau:
1.Xaiv cov khoom siv rwb thaiv tsev zoo.
2. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua: Kev hloov pauv raws sij hawm ntawm cov laus thiab cov khoom hnyav hnyav.
3. Txhim kho cov khoom tiv thaiv overvoltage: txhawm rau txheeb xyuas thiab txwv cov xwm txheej overvoltage.
4. Txhim kho cov cuab yeej ntsuas kub: Tsis tu ncua xyuas qhov kub thiab txias hloov ntawm lub transformer nto.
Cov kev ntsuas no tau zoo tiv thaiv thiab txo qhov tshwm sim ntawm ib feem ntawm qhov tso tawm, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm transformers.
