Lub sij hawm 'Partial Discharge' (PD) tej zaum yuav suab me ntsis kev, tab sis nws yog ib qho tseem ceeb qhia txog 'kev noj qab haus huv' ntawm high- cov khoom siv hluav taws xob xws li transformers. Xav txog yog tias muaj me me "sparks" ntsiag to yug me nyuam nyob rau hauv lub cuab yeej, tsub zuj zuj ntawm lub sij hawm, lub txim yuav yog unimaginable. Nyob rau ntawm no, peb xav tau ib tug muaj peev xwm pab - transformerib nrab tso tawm tester.
Kev tso tawm ib nrab yog dab tsi? Vim li cas nws thiaj tseem ceeb?
Yooj yim muab tso, ib nrab tso tawm yog hais txog qhov tshwm sim ntawm corona tawm qhov twg lub zog hluav taws xob hauv qee qhov ntawm cov rwb thaiv tsev ntawm high- cov khoom siv hluav taws xob yog qhov siab tab sis tsis txaus ua rau tag nrho - lub sijhawm rwb thaiv tsev tawg. Txawm hais tias qhov tso tawm no tsis zoo li qhov ua tsis zoo, nws yuav ua rau cov khoom siv hluav taws xob txuas ntxiv, ua rau kev laus, thiab thaum kawg ua rau cov khoom puas tsuaj loj thiab txawm tias hluav taws xob poob.
Dab tsi yog yam uas cuam tshuam rau kev tso tawm ib nrab?
Qhov tsis xws luag hauv cov ntaub ntawv rwb thaiv tsev xws li cov pa paug, impurities, thiab qhov ntom ntom tsis sib xws tuaj yeem dhau los ua "hotbeds" rau kev tso tawm ib nrab.
Cov khoom siv tsim qauv: Cov khoom siv hluav taws xob tsis sib xws tuaj yeem yooj yim tsim cov hluav taws xob hauv cheeb tsam siab ntawm siab -voltage terminals thiab rwb thaiv tsev qhov khoob.
Kev ua haujlwm ib puag ncig: Kub, av noo, plua plav, thiab lwm yam tuaj yeem cuam tshuam rau kev ua haujlwm rwb thaiv tsev.
Cov cuab yeej kev laus: Lub sijhawm dhau los, kev ua haujlwm ntawm cov ntaub ntawv rwb thaiv tsev yuav maj mam poob.
Yuav ua li cas txhawm rau txheeb xyuas "qhov muag kub" ntawm Wuhan UHV Power Technology Co., Ltd?
Yuav ua li cas peb thiaj li tshawb tau thiab teb tau zoo rau cov 'kev phom sij tsis pom'? Qhov no tsis tuaj yeem raug cais tawm ntawm peb tus neeg ua yeeb yam niaj hnub no - lub tshuab hluav taws xob ib nrab tso tawm tester.
Nws yog dab tsi? Raws li lub npe qhia, nws yog ib qho cuab yeej tshwj xeeb tsim los tshawb xyuas qhov tshwm sim ntawm qhov paug tawm hauv siab - cov khoom siv hluav taws xob xws li transformers. Los ntawm kev ntsuas hluav taws xob pulse teeb liab tsim los ntawm kev tawm, peb tuaj yeem txiav txim siab seb puas muaj ib feem ntawm cov khoom siv thiab ntsuas nws qhov hnyav.
Cov cuab yeej twg muaj? Tam sim no, cov cuab yeej kuaj xyuas ib nrab ntawm Wuhan UHV Power Technology Co., Ltd. ntawm kev ua lag luam muaj cov thev naus laus zis paub tab thiab tuaj yeem ua tiav siab - qhov tseeb thiab ntsuas qhov ntsuas. Cov cuab yeej no feem ntau siv cov cuab yeej paub zoo tshaj plaws thiab cov ntaub ntawv ua cov txheej txheem kom paub qhov txawv ntawm ntau hom kev tso tawm thiab muab cov ntaub ntawv ntsuas kev paub zoo.
Yuav ua li cas? Kev ntsuam xyuas feem ntau yog ua thaum cov khoom siv nyob rau hauv lub zog hluav taws xob. Los ntawm kev txuas tus tester mus rau qhov siab -voltage lead los yog nruab nrab point ntawm transformer, thiab siv ib tug tej yam voltage (feem ntau lub hwj chim zaus los yog variable zaus voltage) rau cov cuab yeej, lub twj paj nruag yuav pib mus ntes thiab soj ntsuam ib feem ntawm cov teeb liab tawm.
Ua tib zoo saib xyuas cov ntsiab lus no kom ua rau qhov kev sim siab dua
Txhawm rau ua kom cov txiaj ntsig ntawm transformer ib feem ntawm qhov kev ntsuam xyuas qhov tseeb thiab txhim khu kev qha, ntxiv rau kev tso siab rau cov cuab yeej siv siab, kuj tseem muaj qee cov ntsiab lus uas yuav tsum tau sau tseg:
Xaiv cov kev sim uas tsim nyog: Cov cuab yeej sib txawv thiab kev ua haujlwm yuav xav tau cov kev sim sib txawv (xws li kev kuaj xyuas lub zog ib nrab, kev siv hluav taws xob hloov pauv hauv av, thiab lwm yam). Pab neeg tshaj lij ntawm Wuhan UHV Power Technology Co., Ltd. tuaj yeem muab cov kev daws teeb meem zoo tshaj plaws raws li qhov xwm txheej tiag tiag.
Cov txheej txheem kev ua haujlwm tau zoo: nruj me ntsis ua raws li phau ntawv qhia kev lag luam thiab cov qauv kev lag luam kom ntseeg tau tias qhov chaw sim ruaj khov thiab tsis txhob cuam tshuam sab nraud.
Cov ntaub ntawv tsom xam thiab kev txhais lus: Cov ntaub ntawv xeem ntau dua tsis tas yuav zoo dua, qhov tseem ceeb nyob hauv kev txheeb xyuas thiab kev txhais lus raug. Cov kws tshaj lij engineers tuaj yeem txiav txim siab qhov xwm txheej thiab kev phom sij ntawm kev tso tawm los ntawm ntau qhov ntev xws li waveform, amplitude, thiab zaus.
Kev kuaj ib nrab ntawm cov transformers yog ib feem tseem ceeb ntawm kev ua kom muaj kev nyab xeeb ntawm cov khoom siv fais fab. Los ntawm txoj kev tshawb nrhiav kev tshawb fawb, peb tuaj yeem muab kev ceeb toom ntxov, tiv thaiv teeb meem ua ntej lawv tshwm sim, thiab zam kev poob yam tsis tsim nyog.
Cov lus nug nquag nug (FAQ)
Q1: Puas yuav tso tawm ib nrab yuav ua rau muaj kev puas tsuaj rau transformers? A1: Tsis tas li, kev tso tawm ib nrab yog txheej txheem ntawm kev puas tsuaj. Kev tso tawm me me tuaj yeem tsis muaj qhov cuam tshuam loj rau lub sijhawm luv luv, tab sis kev tso tawm tsis tu ncua tuaj yeem ua kom lub rwb thaiv tsev laus thiab ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav.
Q2: Dab tsi zaus ntawm qhov hluav taws xob zoo tshaj plaws rau kev kuaj ib nrab tawm? A2: Qhov kev sim no feem ntau yog ua nyob rau hauv lub zog zaus (50Hz lossis 60Hz) voltage, tab sis qee zaum kuj muaj qhov sib txawv zaus voltage raug xaiv rau kev sim raws li cov xwm txheej tshwj xeeb los simulate lub xeev ntawm cov khoom siv thaum lub sijhawm ua haujlwm.
Q3: Dab tsi cuam tshuam qhov rhiab heev ntawm lubib nrab tso tawm testermuaj nyob rau qhov kev xeem? A3: Qhov siab dua qhov rhiab heev, qhov zoo dua nws tuaj yeem kuaj xyuas qhov tsis muaj zog ib feem ntawm cov paib tawm, yog li kuaj pom muaj peev xwm tiv thaiv kev puas tsuaj ua ntej thiab txhim kho kev ceeb toom muaj peev xwm tshawb pom.
Q4: Sib nrug ntawm transformers, dab tsi lwm yam khoom siv yuav tsum tau mus kuaj ib nrab? A4: Cov khoom siv hluav taws xob hluav taws xob siab nrog cov txheej txheem rwb thaiv tsev xws li siab - cov kab hluav taws xob hluav taws xob, lub tshuab hluav taws xob, thiab cov tshuab hluav taws xob feem ntau yuav tsum tau kuaj ib feem.
Q5: Cov neeg siv li niaj zaus tuaj yeem kuaj qhov tso tawm ib nrab ntawm lawv tus kheej?
