Dual Canopy Mechanic Electrical Engineering Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov chaw muag khoom ntawm On-Load Tap Changer Tester hauv Suav teb. Thov koj xav tias dawb rau cov lag luam wholesale luv nqi khoom muag ntawm no thiab tau txais cov lus hais los ntawm peb lub hoobkas. Customized xaj yog txais tos.

CovNtawm -Load Tap Changer Tester (OLTC Tester)yog ib qho cuab yeej kuaj mob tshwj xeeb tsim los ntsuas qhov kev ua tau zoo thiab kev mob ntawmNtawm -Load Tap Changers (OLTCs)nyob rau hauv lub hwj chim transformers. Tsis zoo li tus qauv winding resistance testers uas ntsuas qhov zoo li qub, OLTC tester tsom rau ntawmtus cwj pwm dynamicntawm tus kais hloov pauv thaum nws ua haujlwm hloov.

OLTC yog tib qho kev txav mus los txuas nrog lub tshuab hluav taws xob windings thaum lub sijhawm ua haujlwm thiab yog ib qho ntawm cov tsis ua haujlwm feem ntau -cov khoom siv. Qhov no tester siv lubdynamic kuj ntsuas txoj kev(tseem hu ua "txoj kev tam sim no") txhawm rau txheeb xyuas cov txheej txheem hloov pauv ntawm cov kais dej. Los ntawm kev txhaj tshuaj DC tam sim no thiab ntsuas qhov hluav taws xob poob thoob plaws qhov cua thaum lub sij hawm hloov pauv, nws suav cov kev hloov pauv hloov thiab ntsuas qhov tsis kam-vs- lub sij hawm waveform.

Qhov kev tshuaj ntsuam no qhia txog cov teeb meem tseem ceeb ntawm kev siv tshuab thiab hluav taws xob xws likev sib cuag hnav, caij nplooj ntoos hlav nro poob, rwb thaiv tsev degradation, thiab lub sij hawm sib txawv, enabling kev saib xyuas thiab tiv thaiv kev puas tsuaj transformer tsis ua hauj lwm.

1. Kev tiv thaiv kev tiv thaiv substation
Kev soj ntsuam niaj hnub: Raws li kev tiv thaiv kev ntsuas rau cov cuab yeej siv hluav taws xob, kev ntsuas dynamic tau ua ib ntus ntawm -load kais hloov pauv (OLTCs) ntawm hauv - cov kev pabcuam tseem ceeb hloov pauv los tsim cov ntaub ntawv kho mob.
Kev ntsuas qhov xwm txheej: Los ntawm kev sib piv cov ntaub ntawv keeb kwm yav dhau los, cov qib ntawm kev sib tiv tauj thiab cov ncauj lus ntawm kev hloov pauv hloov tau raug soj ntsuam, ua rau kev tshawb pom ntxov ntawm kev pheej hmoo txhaum cai.
2. Kev kuaj xyuas qhov txhaum thiab kev daws teeb meem
Kev tuav tsis zoo: Thaum lub tshuab hloov pauv tau txais kev ua haujlwm ntawm cov roj relay, cov txiaj ntsig tsis zoo Dissolved Gas Analysis (DGA) (piv txwv li, nce qib acetylene), lossis kev tswj tsis tau qhov hluav taws xob, tus kws ntsuas hluav taws xob tau siv los ntsuas sai sai seb qhov teeb meem tshwm sim los ntawm kev ua txhaum sab hauv hauv tus kais hloov pauv.
Fault Type Identification: Waveform analysis enables the characteristic fault signatures, xws li "hu rau sintering," "caij nplooj ntoos hlav breakage," " insulation breakdown," thiab "mechanism jamming."
3. Cov Khoom Siv Tshiab Kev Ua Haujlwm thiab Kev Tshaj Tawm Kev lees txais
Factory/Incoming Inspection: Xyuas kom meej tias lub Hoobkas kev ua tau zoo ntawm tus kais hloov pauv ntawm lub tshuab hloov tshiab tau txais raws li kev lees paub.
Tshaj tawm- Kev lees txais kev kho dua tshiab: Tom qab kev kho dua tshiab lossis cov khoom siv hloov pauv ntawm tus kais hloov pauv, kev sim ua kom muaj zog yog ua kom muaj txiaj ntsig zoo ntawm kev kho thiab ua kom muaj kev nyab xeeb ua haujlwm thaum rov ua haujlwm dua -commissioning.
4. Coj mus rhaub Changer Hom Compatibility
Resistor-Type Kais Changers: Ntsuas qhov kev hloov pauv hloov qhov tseem ceeb thiab waveforms thaum lub sijhawm hloov pauv.
Reactor-Type Tap Changers: Txheeb xyuas qhov hloov pauv thiab cov nthwv dej tam sim no ntawm ceg reactor.
Nqus/Oil-Immersed Types: Muaj feem xyuam rau kev sim cov kais hloov pauv siv ntau yam arc- tua cov xov xwm.

Dab tsi yuav tsum tau ceev faj thaum siv?
Ceeb toom kev nyab xeeb
Kev Ntsuam Xyuas Hauv Kev Thauj Khoom nruj nruj: Nws yog txwv tsis pub ua qhov kev sim thaum lub tshuab hloov pauv ua haujlwm hauv kev thauj khoom. Rau kev sim lub hom phiaj, lub transformer yuav tsum tau muab tshem tawm ntawm qhov kev pab cuam, thiab nws yuav tsum tau xyuas kom meej tias ob lub siab -voltage thiab low-voltage sab tau raug txiav los ntawm lawv cov loads.
Txhim khu kev qha hauv av: Ua ntej kev sim, nws yuav tsum tau ua kom ntseeg tau tias lub tshuab hloov pauv qhov nruab nrab, nws cov ntaub thaiv npog, thiab cov ntsuas ntsuas lub kaw lus yog qhov muaj kev ntseeg siab.
High -Voltage Discharge: Tom qab ua tiav qhov kev sim, cov seem seem inductive yuav nyob twj ywm nyob rau hauv lub transformer windings. Nws yog ib qho tseem ceeb uas yuav tsum tau tso tawm cov windings tag nrho- los ntawm kev siv lub ntsuas ntsuas qhov tso tawm ua haujlwm lossis los ntawm kev siv tus pas nrig tawm tshwj xeeb - txhawm rau tiv thaiv kev raug mob los ntawm lub zog hluav taws xob rov qab.

Kev pabcuam yog dab tsi?

 

Kev Sib Tham Kev Xaiv Tus Qauv: Raws li tus neeg siv lub peev xwm hloov pauv, theem voltage, thiab hom hloov pauv (piv txwv li, hom xws li MR, UC, ABB), peb pom zoo kom tsim nyog qhov ntsuas tam sim no thiab kev teeb tsa ua haujlwm.
Customized Technical Solutions: Rau cov qauv kev hloov pauv tshwj xeeb (piv txwv li, cov reactor tshwj xeeb- hom qauv), peb muab cov qauv ntsuas kev ntsuas thiab cov qauv ntsuas waveform.
Cov Lus Qhia Txog Kev Ua Raws Cai: Peb hais txog cov lus nug txog cov kev cai ntawm cov qauv xws li DL/T 846.6, * Cov Lus Qhia rau Kev Ntsuas Ntawm -Load Kais -Changers*, thiab pab cov neeg siv hauv kev tsim cov phiaj xwm sim uas ua raws li cov lus qhia tshwj xeeb.
Kev Qhia Txog Khoom Muag: Peb muab rau ntawm - qhov chaw lossis kev ua yeeb yaj kiab los qhia seb yuav ua li cas txheeb xyuas qhov tsis raug -xws li kev tiv tauj yaig lossis qhov tawg tawg - los ntawm kev tsom xam waveform.

 

Q1: Vim li cas qhov "dynamic resistance" ntawm ib qho ntawm -load kais changer (OLTC) ntsuas ntau dua li nws qhov kev tiv thaiv zoo li qub?
A: Kev ntsuas kev tiv thaiv zoo li qub (xws li ua los ntawm DC resistance tester) tsuas tuaj yeem cuam tshuam qhov kev tiv thaiv kev tiv thaiv thaum cov neeg raug kaw; nws tsis tuaj yeem qhia qhov xwm txheej ntawm lub cuab yeej thaum lub sijhawm hloov pauv tiag tiag. Thaum lub sijhawm hloov pauv, OLTC dhau los ntawm kev hloov pauv hloov pauv; Yog hais tias cov kev sib cuag yog faulty los yog cov neeg kho tshuab mechanism jams nyob rau lub sij hawm no, arcing los yog overheating yuav tshwm sim. Dynamic resistance ntsuas sau cov kev hloov pauv hloov nkhaus thoob plaws hauv tag nrho cov txheej txheem hloov pauv, yog li ua kom pom cov khoom tsis raug thiab hloov pauv kev sib cuag teeb meem uas ntsuas zoo li qub yuav tsis txheeb xyuas.

Q2: Dab tsi yog qhov "kev hloov pauv hloov" ncov hauv qhov ntsuas waveform sawv cev?
A: Thaum lub sij hawm hloov cov txheej txheem ntawm kev hloov pauv hloov pauv, qhov tam sim no yuav tsum tau ntws los ntawm kev hloov pauv hloov los pab txhawb kev sib hloov. Lub ncov nyob rau hauv lub waveform sawv cev rau qhov tseeb tus nqi ntawm qhov kev hloov pauv resistor. Yog hais tias lub ncov siab heev, nws qhia tau hais tias tsis zoo kev sib cuag los yog ablation ntawm kev hloov kev sib cuag; conversely, yog hais tias lub ncov yog tsawg dhau los yog tsis tuaj, nws yuav qhia ib tug luv luv Circuit Court nyob rau hauv cov kev hloov kev sib cuag los yog ib tug txawv txav mechanical ua hauj lwm (xws li ib tug hla kauj ruam).

Q3: Tus neeg ntsuas no puas tuaj yeem kuaj xyuas "kev ua haujlwm tsis raug" hauv tus kais hloov pauv?
A: Yog, nws tuaj yeem ua tau. Txawm hais tias qhov kev ntsuam xyuas tshwj xeeb ntsuas qhov tsis kam waveform, mechanical faults yog ncaj qha cuam tshuam rau cov yam ntxwv ntawm lub waveform. Piv txwv li:

Lub caij nplooj ntoos hlav tsis txaus: Qhov no ua rau lub sijhawm hloov mus ntev thiab nthuav dav ntawm "cov kauj ruam" hauv lub waveform.
Mechanism jamming: Qhov no ua rau jittering lossis stagnation tshwm sim ntawm qhov nce ntawm ntug ntawm lub waveform.
Hu rau bouncing: Qhov no tshwm sim raws li siab - zaus spikes los yog "glitches" ntawm lub waveform.
Yog li ntawd, kev tsom xam waveform yog ib txoj hauv kev zoo rau kev kuaj xyuas cov khoom tsis raug.
