Thaum lub sijhawm ua haujlwm ntawm cov khoom siv hluav taws xob, cov rwb thaiv tsev yuav maj mam deteriorate nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, kub thiab mechanical vibration rau lub sij hawm ntev, nrog rau tag nrho cov deterioration thiab ib feem ntawm deterioration, ua rau muaj kev puas tsuaj.qhov tsis xws luag.
Ntau yam kev tiv thaiv kev sim, txhua tus nrog nws tus kheej lub zog, tuaj yeem pom qee qhov tsis xws luag thiab cuam tshuam txog kev rwb thaiv tsev, tab sis qhov ntsuas hluav taws xob ntawm lwm txoj kev ntsuas feem ntau qis dua qhov ua haujlwm ntawm cov khoom siv hluav taws xob, tab sis AC tiv thaiv qhov ntsuas hluav taws xob feem ntau. siab tshaj ntawm cov khoom siv fais fab.Kev khiav hauj lwm voltage yog siab, yog li tom qab dhau qhov kev xeem, cov cuab yeej muaj kev nyab xeeb loj, yog li qhov kev sim no tau dhau los ua ib qho tseem ceeb los ua kom muaj kev nyab xeeb.
Txawm li cas los xij, txij li qhov ntsuas hluav taws xob siv hauv AC tiv thaiv qhov ntsuas hluav taws xob ntau dua li qhov kev khiav hauj lwm voltage, qhov hluav taws xob ntau dhau yuav ua rau kom poob ntawm qhov nruab nrab insulating, tsim kom muaj cua sov, thiab tso tawm, uas yuav ua rau kev txhim kho ntawm cov rwb thaiv tsev tsis zoo.Yog li ntawd, hauv kev nkag siab, AC tiv thaiv qhov ntsuas hluav taws xob yog qhov kev sim ua kom puas tsuaj.Ua ntej AC tiv thaiv qhov ntsuas hluav taws xob, ntau yam kev ntsuas tsis muaj kev puas tsuaj yuav tsum tau ua ua ntej.
Xws li ntsuas kev tiv thaiv kev tiv thaiv, kev nqus qhov sib piv, dielectric poob qhov tseem ceeb tanδ, DC to tam sim no, thiab lwm yam, ua tib zoo txheeb xyuas cov txiaj ntsig kev ntsuas los txiav txim seb cov khoom puas ntub lossis muaj qhov tsis xws luag.Yog tias pom tias muaj teeb meem, nws yuav tsum tau kho ua ntej, thiab AC tiv thaiv qhov ntsuas hluav taws xob tuaj yeem ua tiav tom qab tshem tawm qhov tsis xws luag, txhawm rau kom tsis txhob muaj kev puas tsuaj thaum lub sij hawm AC withstand voltage test, nthuav rwb thaiv tsev. tsis xws luag, ncua sij hawm txij nkawm, thiab ua kom cov haujlwm ua haujlwm ntau ntxiv..
Qhov kev ntsuam xyuas no yog siv los txheeb xyuas cov sab nraud tiv thaiv lub zog ntawm kab kawg thiab nruab nrab cov ntsiab lus terminals thiab cov windings uas lawv txuas nrog hauv av thiab lwm yam windings.AC tiv taus qhov ntsuas hluav taws xob yog qhov ncaj qha thiab siv tau zoo tshaj plaws los ntsuas qhov rwb thaiv tsev lub zog ntawm lub transformer.Nws yog ib qho tseem ceeb rau kev nrhiav qhov tsis xws luag hauv zos hauv lub ntsiab rwb thaiv tsev ntawm lub transformer, xws li lub ntsiab rwb thaiv tsev ntawm lub winding yog damp, tawg los yog winding yog xoob thaum lub sij hawm thauj mus los, cov hlau lead nrug tsis txaus, thiab muaj roj nyob rau hauv lub ntsiab rwb thaiv tsev. .Cov teeb meem xws li impurities, huab cua npuas, thiab av adhering rau winding rwb thaiv tsev yog zoo heev.Lub AC tiv taus qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob tuaj yeem ua tau tsuas yog tom qab lub tshuab hluav taws xob tau ntim nrog cov roj insulating tsim nyog, khaws cia nyob twj ywm rau qee lub sijhawm thiab tag nrho lwm yam kev ntsuas hluav taws xob tsim nyog.
HV HIPOT YDQ series roj kuaj transformer
YDQ series roj hom ntsuas transformer txais cov khoom siv tshiab thiab cov thev naus laus zis tshiab, thiab siv sulfur hexafluoride ua qhov nruab nrab.Piv nrog rau cov tsoos roj-immersed test transformer, qhov hnyav ntawm cov roj-hom test transformer tsuas yog 40% -80% ntawm cov roj-immersed test transformer nyob rau hauv tib theem voltage thiab muaj peev xwm.Qhov hluav taws xob theem ntawm ib chav tsev tuaj yeem ncav cuag 300KV, uas yog tshwj xeeb tshaj yog haum rau kev ua haujlwm ntawm qhov chaw.Nws muaj cov yam ntxwv ntawm qhov me me, lub teeb yuag, tsis muaj roj paug, thiab tsis cuam tshuam los ntawm kev hloov pauv huab cua.Lub corona yog qhov me me, qhov kev sim tuaj yeem ua tiav yam tsis muaj nyob ruaj khov thaum tuav ntawm qhov chaw, thiab kev pabcuam lub neej ntev, thiab tsis tas yuav tsum muaj kev saib xyuas.
Khoom npe menyuam yaus: YDQ AC thiab DC SF6 gas test transformers, gas-filled test transformers, high-voltage test transformers, power high-voltage test transformers, ultra-light high-voltage test transformers, cascade high-voltage test transformers, gas-filled test transformers, gas-filled test transformers, gas-filled test transformers, Gas-filled light-duty high-voltage test transformers.
