CovVLF Hipot Testernyob rau hauv Wuhan UHV tuaj yeem pab ntau tus neeg ua haujlwm lub zog ua ntau yam kev ntsuas hluav taws xob yooj yim dua.
Hauv kev ntsuas hluav taws xob hluav taws xob, tiv thaiv qhov ntsuas hluav taws xob yog ib qho tseem ceeb los xyuas kom muaj kev nyab xeeb ntawm cov khoom siv. Txawm hais tias ib txwm muaj hwj chim zaus tiv thaiv qhov ntsuas hluav taws xob tau siv dav, rau cov cuab yeej siv hluav taws xob xws li cables, generators, GIS, thiab lwm yam, qhov ntsuas tam sim no loj, cov cuab yeej loj, thiab kev siv hluav taws xob siab. Nrog rau kev txhim kho thev naus laus zis, ultra- tsis tshua muaj hluav taws xob tiv thaiv hluav taws xob ntsuas hluav taws xob (VLF) tau maj mam hloov cov txheej txheem ib txwm muaj thiab dhau los ua cov kev daws teeb meem tseem ceeb rau kev ntsuas hluav taws xob nruab nrab thiab cov hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob loj. Raws li lub hauv paus ntawm no technology, lubVLF Hipot Testeryog dav siv nyob rau hauv -kev tshuaj xyuas qhov chaw thiab cov cuab yeej xa mus kuaj lub tshuab hluav taws xob vim nws qhov zoo ntawm qhov me me, kev siv hluav taws xob tsawg, thiab kev ntsuas kom raug.
Lub luag haujlwm tseem ceeb ntawm lubVLF Hipot Testeryog ua cov rwb thaiv tsev tiv thaiv kev ntsuas hluav taws xob, uas txhais tau hais tias siv cov zaus tsawg heev (feem ntau yog 0.1Hz, 0.05Hz, lossis 0.02Hz) AC high voltage rau cov qauv ntsuas thiab tswj nws rau lub sijhawm teev los ntsuas cov rwb thaiv tsev tiv thaiv hluav taws xob muaj peev xwm. Thaum cov cuab yeej tsis muaj kev puas tsuaj lossis flashover thaum lub sijhawm kuaj, nws qhov kev ua haujlwm rwb thaiv tsev tuaj yeem raug txiav txim raws li tsim nyog. Qhov project no muaj feem xyuam rau cov khoom siv xws li fais fab cables, cable txuas, generators, motor stators, transformers, thiab GIS, thiab yog siv los xyuas seb lub rwb thaiv tsev txheej puas ntub dej, hnub nyoog, los yog muaj feem cuam tshuam ib feem.
Thaum lub sij hawm tiv thaiv voltage test, lubVLF Hipot Testertuaj yeem synchronously saib xyuas cov dej ntws tam sim no, thiab txiav txim siab qhov nqus cov yam ntxwv thiab qhov poob ntawm qhov nruab nrab rwb thaiv tsev los ntawm kev sau cov kev hloov pauv tam sim no hauv lub sijhawm. Feem ntau cov dej xau tam sim no feem ntau qhia txog kev puas tsuaj los yog cov teeb meem ya raws, yog li kev ntsuas tam sim no kuj yog ib qho tseem ceeb rau kev ntsuam xyuas kev noj qab haus huv. Qee cov qauv siab -kawg kuj tseem tuaj yeem kos cov yam ntxwv tam sim no nkhaus los soj ntsuam cov txheej txheem kev laus ntawm cov rwb thaiv tsev lossis cov dej noo, muab cov ntaub ntawv txhawb nqa rau cov khoom siv tu.
Ntxiv rau, covVLF Hipot Testerkuj tuaj yeem siv rau kev ntsuas kev laus ntawm cov hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob. Rau cov khoom siv uas tau ua haujlwm tau ntau xyoo los yog tsis ua haujlwm rau lub sijhawm ntev, qhov ntsuas ntawm cov rwb thaiv tsev degradation tuaj yeem txiav txim siab los ntawm kev ntsuas qhov ntsuas hluav taws xob thiab kev saib xyuas tam sim no, qhov muaj peev xwm tuaj yeem kuaj tau ua ntej, thiab qhov tsis raug tuaj yeem zam tau thaum lub sijhawm ua haujlwm. Piv nrog rau lub zog zaus tiv taus qhov hluav taws xob, VLF kev sim tuaj yeem ua tiav qhov kev sim nrog lub zog tsawg dua nyob rau hauv tib lub zog hluav taws xob, uas tuaj yeem cuam tshuam txog kev rwb thaiv tsev yam tsis muaj kev puas tsuaj rau cov khoom laus. Yog li ntawd, nws yog qhov tsim nyog rau kev ua haujlwm ua ntej lossis kev tiv thaiv kev ntsuas cov khoom siv.
Qee cov qauv ntawm VLF hipot testers kuj txhawb kev siv online nrog ib feem ntawm kev kuaj xyuas cov pa tawm, uas tuaj yeem saib xyuas thiab txheeb xyuas cov teeb liab tawm thaum siv hluav taws xob siab, yog li txiav txim siab seb puas muaj qhov tsis xws luag hauv cov rwb thaiv tsev. Qhov no "tiv taus voltage + ib nrab tawm" kev sib koom ua ke tau dhau los ua ib qho tseem ceeb ntawm kev kuaj xyuas rwb thaiv tsev rau cov cables thiab cov motors loj, uas tuaj yeem txhim kho qhov tseeb thiab kev ntseeg siab ntawm kev sim.
Hauv kev teeb tsa, kev ua haujlwm, thiab kev saib xyuas cov khoom siv hluav taws xob,VLF hipot testerskuj yog cov khoom siv feem ntau siv rau kev xa mus thiab kev kuaj kev tiv thaiv. Raws li lub teb chaws tus qauv, nruab nrab thiab high voltage cables yuav tsum undergo ultra- tsawg zaus tiv thaiv voltage kuaj ua ntej muab tso rau hauv lub lag luam los xyuas seb cov txheej txheem tsim thiab rwb thaiv tsev zoo raws li cov qauv. Los ntawm kev sim, tsis tsuas yog peb tuaj yeem paub meej tias lub cable puas muaj kev nyab xeeb kev ua haujlwm, tab sis peb kuj tuaj yeem zam kev ua haujlwm raug mob los ntawm qhov muaj peev xwm rwb thaiv tsev tsis zoo.
Feem ntau, cov khoom kuaj tseem ceeb uas tuaj yeem ua tiav los ntawm covVLF Hipot Testersuav nrog kev ntsuas hluav taws xob tiv thaiv hluav taws xob, kev ntsuas hluav taws xob tam sim no, kev ntsuas hluav taws xob tiv thaiv kev laus, kev kuaj pom ib nrab, nrog rau kev xa xov hluav taws xob thiab khoom siv thiab kev tiv thaiv kev sim. Nws tuaj yeem tsis tsuas yog ntsuas qhov ntsuas kev tiv thaiv kev noj qab haus huv ntawm cov cuab yeej siv, tab sis kuj tseem tuaj yeem pab cov neeg ua haujlwm ua haujlwm thiab tu cov neeg ua haujlwm txhawm rau txheeb xyuas qhov ua yuam kev ua ntej.
