DC Hi-pot Test yog dab tsi?
DC Hi-pot Test ua haujlwm raws li qhov siab -voltage direct current (HVDC) withstand voltage tester rau ntsuam xyuas DC rwb thaiv tsev zog hla fais fab cables, motor windings, transformer bushings, switchgear, and similar apparatus. Nws ua haujlwm los ntawm kev siv qhov ntsuas DC tswj qhov hluav taws xob rau cov khoom siv raws li kev soj ntsuam thiab taug qab seb qhov xau tam sim no coj li cas- ob qho tib si hauv qhov loj thiab dhau sijhawm. Cov yam ntxwv tam sim no qhia seb qhov rwb thaiv tsev puas tuaj yeem tuav tau nyob rau hauv kev ntxhov siab, thiab seb puas muaj kev puas tsuaj los yog kev puas tsuaj hauv cheeb tsam.
Tawm tsam AC tiv thaiv kev hloov hluav taws xob, DC mus kom ze coj tau qhov zoo ntawm thaj chaw. Lub hardware nyob twj ywm ntau compact, draws tsawg zog, thiab qhia tau hais tias txo rhiab heev rau qhov zoo ntawm qhov chaw muab khoom. Cov kws kho mob tuaj yeem thauj nws sai thiab muab tso rau hauv qhov chaw uas lub peev xwm loj yog txwv lossis qhov teeb meem ceev ceev.
Yam khoom twg siv tau rau?
HVDC Cable: Rwb thaiv tsev pov thawj rau siab -voltage DC kis cov haujlwm.
XLPE Cable (Ceeb Toom: Kev siv yuav tsum raug txiav txim siab raws li cov qauv kev lag luam).
Lub cev muaj zog / Generator Windings: Stator winding rwb thaiv tsev tiv taus qhov ntsuas hluav taws xob thiab kev ntsuas.
Transformer Windings thiab Bushings: DC tiv taus qhov ntsuas hluav taws xob thiab rwb thaiv tsev.
Switchgear thiab Control Devices: Insulation verification and acceptance tests.
Capacitors / Surge Arresters: Cov yam ntxwv ntawm rwb thaiv tsev pov thawj thiab kev tshuaj xyuas lub Hoobkas.
Rwb thaiv tsev cov ntaub ntawv / Cheebtsam Zoo Kev Tshuaj Xyuas: Chaw tsim tshuaj paus lub Hoobkas tshuaj xyuas thiab kev tshawb fawb daim ntawv thov.
Dab tsi yuav tsum tau ceev faj thaum siv?
Ua tib zoo siv hluav taws xob tua hluav taws xob thiab kev sib cais: Cov khoom nyob rau hauv kev sim yuav tsum raug txiav tawm ntawm lub operating system. Txheeb xyuas qhov hluav taws xob, txuas lub xaim hauv av, thiab khi ib lub cim. Ua raws li kev ntsuas kev nyab xeeb.
Hauv av ua ntej txuas cov hluav taws xob siab: Cov kab hluav taws xob sib txuas yuav tsum yog tus qauv; voltage nce yog nruj me ntsis txwv tsis pub thaum lub siab -voltage kawg tsis txuas.
Tag nrho tso tawm ua ntej disconnecting: DC high voltage yuav sau nqi nyob rau hauv capacitive rwb thaiv tsev. Kev tso tawm yuav tsum ua kom tiav (ntau qhov tso tawm thiab tos tau pom zoo). Disconnect tsuas yog tom qab paub meej tias qhov seem voltage yog xoom.
Teem ib qho kev tsim nyog rau qhov pib tam sim no: rhiab heev rau qhov pib yuav ua rau muaj kev ceeb toom vim av av lossis qhov chaw paug; lenient dhau qhov pib yuav ua rau tsis pom kev. Nws raug nquahu kom teeb tsa qhov pib raws li cov cai thiab cov ntaub ntawv keeb kwm.
Ua tib zoo saib xyuas thaum lub zog nce ntxiv: Kev hloov tam sim no tam sim no, nce tsis ruaj khov, lossis tshaj qhov txwv yog cov cim txawv txav. Qhov kev sim yuav tsum tau nres tam sim ntawd thiab qhov teeb meem tshawb xyuas.
Nco ntsoov qhov siv tau ntawm XLPE cables: Ua ntej siv DC tiv taus hluav taws xob ntawm XLPE cables, paub meej tias lawv ua tau raws li cov cai tshiab.
Ib leeg-tus neeg ua haujlwm raug txwv nruj: High- qhov ntsuas hluav taws xob yuav tsum tau ua los ntawm ob tus neeg (tus neeg ua haujlwm + tus saib xyuas). Yuav tsum tau teeb tsa kev tiv thaiv kev nyab xeeb thiab cov cim ceeb toom.
Cov ntaub ntawv ib puag ncig: Kub, av noo, thiab cov qauv ntsuas kub muaj qhov cuam tshuam loj rau cov txiaj ntsig; cov no yuav tsum tau sau tseg.
FAQ
Q1: Dab tsi yog qhov txawv ntawm DC Hi-pot Test thiab AC Hi-pot Test?
A: DC tiv taus cov khoom siv ntsuas hluav taws xob sib zog thiab yuav tsum muaj lub peev xwm tsawg dua, muab kev saib xyuas tam sim no ncaj qha; AC tiv taus qhov ntsuas hluav taws xob ntau ze ze ntawm kev ua haujlwm thiab tsim nyog rau ntau yam xwm txheej.
Q2: Puas yog DC Hi-pot Tester haum rau kuaj XLPE cables?
A: Kev siv tau ntawm DC tiv thaiv qhov ntsuas hluav taws xob rau XLPE cables yuav tsum tau txiav txim siab ua ke nrog cov cai tshiab (qhov no yog qhov teeb meem ntawm kev sib tham hauv kev lag luam). Nws raug pom zoo kom paub meej tias tus qauv siv tau ua ntej xaiv txoj kev xeem.
Q3: Qhov cuam tshuam tam sim no ntawm qhov teeb meem cuam tshuam dab tsi?
A: Tsis muaj kev sib koom ua ke. Kev txiav txim siab yuav tsum tau ua raws li cov khoom siv, qib voltage, cov ntaub ntawv keeb kwm, thiab kev txwv kev txwv; kev hloov pauv tseem ceeb dua li qhov tseem ceeb ntawm ib leeg.
