Khoom Description
CovIb nrab Tso Tawm (PD) Testeryog ib qho cuab yeej kho mob rhiab heev uas tsim los txheeb xyuas thiab tshuaj xyuaskev tso tawm ib nrabnyob rau hauv high-voltage (HV) rwb thaiv tsev systems. Ib nrab tso tawm yog ib qho hluav taws xob tso tawm hauv ib cheeb tsam uas tsuas yog ib feem txuas cov rwb thaiv tsev ntawm cov conductors, thiab nws yog ib qho tseem ceeb qhia ntawm rwb thaiv tsev degradation.
Tsis zoo liHipot testersuas siv hluav taws xob siab los ntsuas qhov kev puas tsuaj (kev puas tsuaj "mus / tsis yog- mus"), PD testers ua haujlwm ntawm qhov qub lossis siab me ntsis kev khiav hauj lwm voltages los xyuasincipient faultstsis ua puas lub rwb thaiv tsev. Qhov no ua rau PD kuaj lub hauv paus ntawmCov xwm txheej -Kev Kho raws li (CBM)rau cov khoom muaj zog tseem ceeb.
Peb PD tester txhawb ntau yam kev tshawb nrhiav, suav nrogUltra{0}}High Frequency (UHF), Transient Earth Voltage (TEV), Ultrasonic, thiabSiab -Frequency Current Transformer (HFCT)txoj kev. Nws enables engineers los txheeb xyuas covhom, hnyav, thiabqhov chawntawm rwb thaiv tsev tsis xws luag nyob rau hauv GIS, fais fab cables, transformers, thiab switchgear, yooj yim rau kev cuam tshuam raws sij hawm ua ntej kev puas tsuaj loj tshwm sim.

FAQ
Q1: Dab tsi yog qhov sib txawv ntawm qhov kev kuaj tawm ib nrab thiab tiv thaiv qhov ntsuas hluav taws xob? Ib tug puas tuaj yeem hloov tau rau lwm tus?
A: Lawv hloov tsis tau rau ib leeg; es, lawv yog complementary.
Kev ntsuas hluav taws xob tiv thaiv yog qhov kev sim "kev puas tsuaj" lossis "tso cai"; los ntawm kev siv qhov hluav taws xob siab tshaj qhov kev khiav hauj lwm voltage, nws paub tseeb tias cov rwb thaiv tsev puas tawg. Nws tsuas tuaj yeem qhia koj yog tias qhov rwb thaiv tsev yog "twb ua tsis tiav."
Kev kuaj paug ib nrab yog qhov "tsis yog-kev puas tsuaj" lossis "kev kuaj mob"; nws pom faint tawm teeb liab ntawm kev khiav hauj lwm voltage theem. Nws tuaj yeem qhia rau koj yog tias qhov rwb thaiv tsev yog "deteriorating" lossis yog tias muaj qhov tsis xws luag latent.
Kev pom zoo: Kev ntsuas hluav taws xob tiv thaiv yog xav tau rau kev lees txais cov cuab yeej tshiab; rau kev saib xyuas hauv - cov cuab yeej pabcuam, kev kuaj tawm ib nrab yog qhov kev xaiv zoo tshaj plaws, vim tias nws tuaj yeem kuaj pom thaum ntxov- theem tsis xws luag uas tuaj yeem ntsuas qhov ntsuas hluav taws xob tsis tuaj yeem txheeb xyuas, yam tsis muaj kev puas tsuaj rau lub rwb thaiv tsev.
Q2: Tus qauv PRPD yog dab tsi? Dab tsi yog nws siv?
A: PRPD (Phase-Resolved Partial Discharge) yog ib daim ntawv qhia kev faib tawm ib feem ntawm qhov tso tawm amplitude tawm tsam lub kaum sab xis voltage. Nws ua raws li "tus ntiv tes" rau kev ua txhaum tshwj xeeb.
Internal Void Discharge: Feem ntau nthuav tawm "luv- pob ntseg" zoo li kev faib tawm, tshwm nyob ze ntawm qhov siab tshaj qhov hluav taws xob.
Surface Discharge: Tshaj tawm qhov dav dav, feem ntau tshwm nyob ze ntawm qhov hluav taws xob xoom- hla cheeb tsam.
Floating Electrode Discharge: Tus qauv nthuav tawm qhov tsis xwm yeem, tawg "ntiv tes-zoo li" faib.
Los ntawm kev txheeb xyuas cov qauv PRPD, cov kws tshaj lij tuaj yeem txheeb xyuas hom thiab qhov hnyav ntawm qhov tsis xws luag.
Q3: Nws puas tuaj yeem kuaj xyuas qee qhov tso tawm hauv GIS yam tsis muaj kev cuam tshuam lub zog?
A: Yog, nws yog. Qhov no yog qhov txiaj ntsig tseem ceeb ntawm kev tshawb nrhiav PD.
Txoj Kev UHF: Los ntawm kev siv UHF sensors mounted rau ntawm GIS enclosure (los yog sensors ib ntus ntsia ntawm lub qhov rais tshuaj ntsuam los yog waveguides), sab hauv paug yuav ntes tau thaum cov khoom tseem energized.
TEV Txoj Kev: Los ntawm kev ntsuas Transient Earth Voltage ntawm qhov chaw ntawm GIS enclosure, kev tshawb nrhiav tuaj yeem ua tau zoo sib xws hauv cov xwm txheej muaj zog.
Txoj kev Ultrasonic: Los ntawm tau txais cov cim acoustic ntawm qhov chaw ntawm GIS enclosure, kev kuaj pom kuj tuaj yeem ua tau thaum cov cuab yeej tseem muaj zog.
