Hloov pauvSweep Frequency Response Analysis (SFRA): Ib qho tseem ceeb los xyuas kom muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob
Transformers yog cov khoom tseem ceeb hauv daim phiaj hluav taws xob, thiab lawv txoj kev ntseeg tau ncaj qha cuam tshuam rau kev ua haujlwm ntawm hluav taws xob. Raws li ib txoj hauv kev zoo tshaj plaws rau kev ntsuam xyuas cov xwm txheej ntawm cov transformers, cheb zaus teb tshuaj ntsuam xyuas (SFRA) siv qhov no tsis yog -invasive diagnostic cov txheej txheem kom tau txais cov ncauj lus kom ntxaws rau cov neeg kho tshuab thiab hluav taws xob mob ntawm transformer windings thiab cores.
Thaum lub sij hawm SFRA xeem, ib tug series ntawm low-voltage sinusoidal signals yog siv rau lubtransformer windings, nrog cov lus teb ntsuas ntawm ntau zaus. Los ntawm kev tshuaj xyuas cov lus teb zaus, cov kws tsim khoom tuaj yeem tshawb xyuas cov teeb meem xws li winding deformation, kev hloov pauv, lossis cov teeb meem tseem ceeb. Cov kev hloov pauv hloov maj mam tuaj yeem tsis pom nyob rau hauv kev sim niaj hnub tab sis tuaj yeem qhia qhov ua yuam kev. Los ntawm kev sim SFRA tsis tu ncua, cov tuam txhab siv hluav taws xob thiab cov chaw lag luam muaj peev xwm ua haujlwm kho lub sijhawm, txo qis qis, thiab txuas ntxiv lub neej kev pab cuam ntawm transformers.
Ntawm Goldhome Hipot, peb muab cov neeg siv khoom nrog cov kev kuaj mob txhim khu kev qha rau cov khoom siv hluav taws xob. Peb lub cuab yeej kuaj xyuas ua kom yooj yim rau kev ntsuas SFRA, ua rau cov kws tshaj lij los xyuas kom meej qhov kev hloov pauv thiab kev nyab xeeb ntawm kev ua haujlwm. Txawm hais tias SFRA yuav tsum muaj kev ntsuam xyuas tus kws tshaj lij, nws tau lees paub dav dav rau nws lub peev xwm los kuaj xyuas ntxov - theem ua txhaum.
KVRZ-S SFRA Analyser, tsim los ntawm Goldhome Hipot, ntiav American DDS digital high-ceev scanning thev naus laus zis los xa cov kev kuaj xyuas qhov tsis raug, suav nrog winding deformation, bulging, displacement, skewing, inter-tig short circuits, thiab theem- Tsis zoo li cov neeg kuaj pom zoo, cov cuab yeej no muaj ob hom kev tshuaj ntsuam xyuas raws li cov qauv hauv Suav teb cov qauv kev qhia -linear scanning thiab segmented zaus scanning-nrog ntau zaus ntawm 0.5kHz txog 10MHz. Nws ua tiav ultra{11}} daws teeb meem siab nrog txog 40,000 scan ntsiab lus.'Peb cov kev daws teeb meem SFRA tshiab yog qhov tseem ceeb hauv kev ua haujlwm ntawm kev kwv yees txij nkawm rau lub zog hloov hluav taws xob,' hais Mr.Li, Tus Thawj Coj ntawm Goldhome Hipot. 'Tam sim no, 9,078 cov neeg siv khoom thoob ntiaj teb tau siv cov thev naus laus zis no.'
Thaum lub sijhawm ua haujlwm tsis ntev los no ntawm 220 kV substation hauv nruab nrab Suav teb, KVRZ-S cov cuab yeej ua tiav tau tshawb pom axial hloov chaw hauv qhov qis-voltage winding ntawm 160 MVA transformer-ib qho teeb meem uas tsis tau pom yav dhau los siv cov qauv DC tsis kam thiab cov khoom siv hluav taws xob poob. Tom qab kev soj ntsuam sab hauv tau lees paub qhov teeb meem, tso cai rau kev tswj xyuas cov phiaj xwm kom ua tiav thiab tiv thaiv qhov ua tsis tau zoo. Rick Jason, tus thawj tswj hwm substation koom nrog hauv txoj haujlwm, piav qhia: "Goldhome Hipot's SFRA cov cuab yeej cawm peb ntau dua $ 500,000 hauv lub sijhawm poob thiab cov khoom siv hloov pauv nrog lawv qhov tseeb."
Goldhome Hipot kev nqis peev hauv SFRA thev naus laus zis qhia txog lub tuam txhab kev cog lus rau kev tshawb fawb thiab kev tsim kho, uas yog raws li kev paub ntau xyoo.
Goldhome Hipot kev nqis peev hauv SFRA thev naus laus zis yog ua raws li nws txoj kev cog lus rau kev tshawb fawb thiab kev tsim kho, uas tau txais kev txhawb nqa los ntawm kaum- pab pawg kws tshaj lij thiab koom tes nrog kev koom tes nrog cov tsev kawm qib siab. Lub tuam txhab 10,000-square- meter cov chaw tsim khoom ua kom muaj kev tswj xyuas nruj, nrog rau tag nrho cov khoom lag luam raug kev ntsuas thib peb thiab lub Hoobkas lees txais kev kuaj ua ntej xa khoom.
