Qhov zoo thiab kev siv ntawm FRA Analyzer Cov Khoom Siv Hluav Taws Xob hauv Kev Ntsuas Hluav Taws Xob
Goldhome Hipot FRA analyzer (Frequency Response Analyzer), leveraging lub tuam txhab lub xyoo ntawm kev txawj ntse nyob rau hauv siab -voltage fais fab kev ntsuam xyuas thiab kev txhawb los ntawm ntau tshaj 45 patents, yog ib tug meej, npaum, thiab txawj ntse kev xeem ntaus ntawv. Nws yog dav siv nrog ntau hom kev sim ntsuas thoob plaws hauv kev lag luam fais fab thiab lwm yam haujlwm. Cov ntaub ntawv tshwj xeeb qhia tau hais tias nws qhov kev ua tau zoo thiab cov txiaj ntsig ntawm daim ntawv thov yog kev lag luam - ua, nrog cov kev ntsuas ntsuas kom muaj nuj nqis tag nrho qhia txog qhov zoo ntawm cov khoom los txhawb cov neeg siv nrog kev sim thiab kev ua haujlwm zoo thiab kev saib xyuas.
Cov khoom lag luam cov txiaj ntsig tseem ceeb yog cov ntaub ntawv- thim rov qab, qhov tseeb kom muaj nuj nqis, thiab sib npaug siab precision nrog cov neeg siv- kev phooj ywg.
Ua ntej, nws qhov ntsuas qhov tseeb mus txog qhov kev lag luam sab saum toj. Ua haujlwm digital Fourier kev koom ua ke, nws nthuav tawm cov yam ntxwv zoo ntawm lub suab nrov nrog rau qhov tseeb ntawm qhov tseeb.Tsawg dua lossis sib npaug li 0.001%. Nws cov dynamic ntau mus txog 140dB, ho ntau tshaj qhov kev lag luam nruab nrab tus qauv ntawm120 dB.Qhov no ua rau kom meej meej ntes cov zaus teb cov yam ntxwv ntawm cov khoom ntsuas, nrog ntsuas qhov yuam kev tswj hauv± 0.1dB (+10dB rau -40dB zaus band). Ua raws li thoob ntiaj teb IEC 60076-18: 2012 thiab cov qauv hauv tsev DL / T 911-2016, nws pom txawm tias feeb electromechanical variations nrog precision.
Thib ob, nws muaj kev ua haujlwm zoo tshaj plaws. Nruab nrog kev xaiv ntau yam tsis siv neeg thiab kev sib koom ua ke tsis siv neeg ua haujlwm, nws tshem tawm qhov xav tau kev hloov kho nyuaj los ntawm cov kws tshaj lij. Ib qho kev ntsuas winding tsuas siv 90 vib nas this, sawv cev rau a 20-40xefficiency txhim kho piv rau 30-60 feeb ntsuas lub sij hawm ntawm cov twj paj nruag ib txwm muaj. Nws txhawb nqa ib txhij tso saib ntawm ntau qhov nkhaus (txog 8 nkhaus) thiab tsis siv neeg ntsuas ntsuas, txo cov sijhawm ua cov ntaub ntawv kom qis dua 10 vib nas this thiab txo cov nqi zog.
Thib peb, nws muab cov ntaub ntawv meej meej rau kev nyab xeeb kev sib raug zoo. Featuring floating input/output circuits nrog 5000V voltage rho tawm - deb tshaj qhov kev lag luam tus qauv ntawm600VKev sib cais- nws tiv taus siab -voltage cuam tshuam, tiv thaiv ob tus neeg tsav tsheb thiab cov khoom siv. Cov cuab yeej loj yog compact ntawm 470mm × 280mm × 360mm, hnyav xwb15kg uakom yooj yim txav tau yooj yim thiab haum rau ntawm -qhov chaw kuaj mob. Nws ua haujlwm ruaj khov hauv ambient kub xws li-10℃rau 45 degreethiab txheeb ze humidity Tsawg dua los yog sib npaug li 95%, yoog mus rau ntau haiv neeg hauv av muaj peev xwm sim scenarios.
Plaub, nws cov kev ua haujlwm dav dav yog suav tau los ntawm cov ntaub ntawv. Nws txhawb ntau hom nrog rau kev ntsuas impedance thiab voj nce kev ntsuas thoob plaws1 Hz txog 15 MHzNtau zaus, khw muag khoom ntau dua 100,000 cov ntaub ntawv xeem cov ntaub ntawv, ua haujlwm suav lej thiab kuaj xyuas qhov tsis raug, thiab ua kom haum rau cov khoom sim nrog lub peev xwm ntawm 6pF mus rau250μF, suav nrog ntau yam kev xeem yuav tsum tau ua.
Nws txoj kev siv dav dav yog pom los ntawm cov ntaub ntawv pob zeb thoob plaws ntau qhov chaw, suav nrog lub zog, kev tshawb fawb, thiab kev lag luam. Hauv kev lag luam fais fab, nws feem ntau yog siv rau kev kuaj xyuas winding deformation nyob rau hauv lub zog transformers ntsuas ntawm 6kV thiab siab dua. Yog tsis qhib lub hau los yog disassembly, SFRA txoj kev tuaj yeem ntes cov tshuab deformation me me li 0.1 hli hauv windings. Hauv kev ntsuas qhov tseeb ntawm220 kV uasubstations, nws tuaj yeem raug ntes cov kev hloov pauv txawv txav nrog lub amplitudeNtau dua lossis sib npaug li 0.5dBnyob rau hauv lub100-300 kHzzaus band, muab cov lus ceeb toom ntxov rau winding defects thiab core faults. Ua kom tiav qhov yuam kev nrhiav tus nqi ntawm 99.2%, nws txo cov khoom siv downtime ntau dua 60%. Tau txais kev pom zoo los ntawm ntau tshaj 300 lub chaw muab hluav taws xob thiab 200 lub chaw tsim hluav taws xob thoob tebchaws, nws txuag cov neeg siv ntau dua ib lab yuan ib xyoos ib zaug hauv kev ua haujlwm thiab tu cov nqi. Hauv kev siv hluav taws xob thiab kev lag luam, nws ua tiav kev ntsuas qhov tseeb ntawm ± 0.01dB rau kev ntsuas impedance ntawm cov khoom siv hluav taws xob, cov khoom siv, thiab cov khoom siv. Switching fais fab mov voj yam ntxwv kuaj muab lub sij hawm tebTsawg dua los yog sib npaug li 5ms, thaum AC impedance nrhiav kom tau rau piezoelectric ntsiab thiab roj hlwb tswj tus nqi yuam kevTsawg dua los yog sib npaug li 0.5%. Cov thev naus laus zis no pab cov lag luam txo cov khoom lag luam R & D los ntawm 15%thiab boost zoo pass tus nqi los ntawm 8%. Hauv kev tshawb fawb txog kev tshawb fawb, cov khoom txhawb nqa cov khoom siv hluav taws xob cov yam ntxwv kev tshawb fawb ntawm cov tsev kawm qib siab thiab cov chaw tshawb fawb los ntawm kev muab cov ntaub ntawv ntsuas siab siab txog li -20,000cov ntsiab lus ib zaug, nrog cov ntaub ntawv rov ua yuam kevTsawg dua los yog sib npaug li 0.04μmol / mol, xa cov ntaub ntawv txhim khu kev qha rau kev tsim kho thev naus laus zis. Tsis tas li ntawd, cov khoom lag luam raug xa mus rau siab - cov khoom siv hluav taws xob kuaj hauv kev tsheb ciav hlau, roj av, metallurgy, thiab lwm yam lag luam. Nws tau ua haujlwm ntau dua 500 lub lag luam, ua tiav cov cuab yeej nruab nrab lub sijhawm nruab nrab ntawm kev ua tsis tiav (MTBF) ntawm8,000teev thiab tus neeg siv txaus siab ntawm98.5%.
Raws li ib qho ntawm Goldhome cov cuab yeej ntsuas tseem ceeb, FRA analyzer qhia nws lub peev xwm los ntawm kev ntsuas kom muaj nuj nqis. Kev sib koom ua ke txiav- thev naus laus zis thev naus laus zis nrog cov kev xav tau, nws muab cov lus qhia meej, ua tau zoo, thiab muaj kev nyab xeeb cov lus teb rau cov kev daws teeb meem thoob plaws hauv kev lag luam. Qhov no txhim kho cov khoom siv tu kom zoo, txo cov kev pheej hmoo tsis ua haujlwm, thiab ntxiv dag zog rau Guodian Huamei txoj haujlwm tseem ceeb hauv siab - qhov ntsuas hluav taws xob.
