SFRA kuaj yog dab tsi?

A SFRA TEST, uas sawv rauCheb zaus, yog qhov rhiab heev thiab tsis muaj kev cuam tshuam ntawm cov txheej txheem kuaj mob uas siv tau los ntsuas qhovneeg kho tshuab thiab hluav taws xob kev vam meej ntawm cov hluav taws xob fais fab(thiab qee zaum lwm yam khoom siv xws li reactors, cov tshuab hluav taws xob, lossis ntiv tes xoo hluav taws xob "thoob plaws ntawm zaus.

Ntawm no yog kev tawg ntawm nws yog dab tsi, nws ua haujlwm li cas, thiab vim li cas nws tseem ceeb:

Lub ntsiab lus tseem ceeb:

Lub teeb liab qis-voltage sinusoidal tau txhaj rau hauv ib qho winding ntawm transformer .

Cov paib teb chaws (voltage lossis tam sim no) yog ntsuas ntawm lwm lub winding (lossis qee zaum tib lub winding) .

Qhov no yog rov ua dua thoob plaws ntau ntawm cov zaus, feem ntau los ntawm20 hz (lossis qis dua) txog li 2 mhz (lossis siab dua).

TusHloov Chaw Ua Haujlwm(Feem ntau cov piv ntawm cov zis tawm, qhia raws li qhov ntau hauv DB thiab plotted tiv thaiv zaus rau txhua qhov kev ntsuas teeb tsa {}}

Txoj kev "ntiv tes" lub tswvyim:

Qhov tshwm sim zaus muaj cov ntsiab lus teb tshwj xeeb rau cov cim ntawm lub cev thiab hluav taws xob ntawm lub sijhawm ntawd thaum lub sijhawm ntawd .

Nws qhia txog kev sib cuam tshuam nyuaj ntawm induction, kev tawm tsam, tseem ceeb, classication txheej, thiab lwm cov khoom siv sab hauv .

Xav txog nws zoo li tus transformer qhov tshwj xeeb "kos npe" lossis "ntiv tes ."

Lub Hom Phiaj & Nws Ntes:

Ntes kho cov hloov pauv / puas tsuaj:Qhov no yog lub zog tseem ceeb ntawm sfra .}} txawm hloov kho lub cev cov ntsiab lus {}} nws tuaj yeem ntes:

Winding deformation:Radial buckling, axial kev hloov pauv, tilting, hoop buckling .

Winding Alplacement:Hloov ntawm tag nrho windings sib txheeb ze rau cov tub ntxhais lossis lwm yam windings .

Tub ntxhais txav:Kev hloov lossis kev puas tsuaj rau cov tub sab tub ntxhais lossis core clamping qauv .

Xoob plugings:Kev poob ntawm clamping siab .

Faulty on-load Kov Changer (OLTC) Hu:Kev sib tiv tauj tsis zoo hauv cov kais dej tsis zoo .

Luv lem:(Txawm hais tias lwm qhov kev kuaj ib yam li tig reculence lossis qis voltage imfulse (Lvi) tej zaum yuav muaj ntau dua kev pib ua ntej, .

Kev puas tsuaj los ntawm kev xa khoom, tuav, lossis yuam kev:Kuaj pom kev puas tsuaj los ntawm cov tub rog luv luv, cov kev lom zem seismic, lossis kev thauj mus los yog ntxhib {}}

Yuav ua li cas nws ua haujlwm rau kev kuaj mob:

Kev sib piv yog tus yuam sij:Qhov kev kuaj mob tshaj plaws yogmuab pivTam sim no SFRA ntsuas rau:

Cov theem pib ntsuas:Coj thaum transformer yog tshiab, noj qab nyob zoo, lossis tom qab kev pabcuam loj (cov qauv kub) .

Ntu:Muab piv rau kauj ruam zoo ib yam (e {{{0} g}}}}}}}} {.

Sib khub Winding:Muab cov lus sib piv zoo sib xws (e {{{0} g ., hv-lv vs {} hv-lv) {5}.

Yav dhau los ntsuas:Khiav kev hloov pauv dhau sijhawm .

Tshuaj xyuas kev sib txawv:Cov kev sib txawv tseem ceeb nyob rau hauv cov duab, qhov ntau, lossis resonant zaus ntawm cov ntawv qhia txog kev hloov lub cev lossis teeb meem {{} cov kws tshaj lij txheeb xyuasqhov twgNyob rau hauv zaus spectrum qhov kev sib txawv tshwm sim rau pinpoint cov hom yuav zoo li thiab qhov chaw ntawm qhov teeb meem:

Tsawg zaus (<1 kHz):Feem ntau muaj kev cuam tshuam tseem ceeb thiab ntau zog winding txav .

Mid zaus (1 khz - 100 cmz):Nkag siab rau deformations thiab cov chaw tsis huv nyob hauv cov windings loj thiab ntawm windings .

High Frequencies (>100 kHz):Nkag siab txog cov teeb meem nrog cov ua, coj mus rhaub pauv, thiab winding winding deformations .

Cov Ntawv Qhia Tseem Ceeb & Cov txiaj ntsig:

Kev Ntsuam Xyuas Kev Mob:Cov cuab yeej tseem ceeb rau Transformer Kev Kho Mob thiab Lub Neej ncua sij hawm txuas ntxiv .

Commissioning:Txheeb xyuas qhov kev puas tsuaj tshwm sim thaum thauj khoom / kev teeb tsa (sib piv cov Hoobkas hauv paus rau kev ntsuas kev ntsuas) {}}}}

Tom qab yuam kev:Soj ntsuam sab hauv kev puas tsuaj tom qab-ua txhaum (luv luv ntawm lub network) .

Txij Nkawm:Txheeb xyuas cov teeb meem tsim ua ntej lawv ua rau kev puas tsuaj tsis ua hauj lwm .

Tswjhwm Zoo:Thaum lub sijhawm tsim thiab kho .

Non-invasive & offline:Ua nrog transformer de-energized, xav tau tsuas yog cov roj voltage tsawg. tsis tas yuav txi roj lossis qhib lub tank {{3}

Heev rhiab:Tuaj yeem tshawb pom cov neeg kho tshuab me me hloov uas lwm qhov kev sim yuav nco .

Lub Hom Phiaj:Muab graphical, quaritative cov txiaj ntsig rau kev tsom xam thiab sib piv .
