Dab tsi yog Ncej -Mounted Transformer?

 

Ib tug ncej-mounted transformer yog ib tug faib transformer ntsia rau ntawm tus ncej hluav taws xob. Nws yog siv los hloov siab - hluav taws xob hluav taws xob (xws li 11kV / 33kV) los ntawm daim phiaj hluav taws xob mus rau qis- hluav taws xob hluav taws xob (xws li 120/240V, 230V) tsim nyog rau cov neeg nyob hauv, kev lag luam, thiab cov neeg siv khoom me me. Piv rau hauv av los yog ncoo-mounted transformers, nws muaj qhov zoo xws li cov hneev taw me me, cov nqi qis dua, thiab tsim nyog rau cov xwm txheej thauj khoom.

 

 

Dab tsi yog Hom Ncej -Mounted Transformers?

 

Ncej-mounted transformers tuaj yeem faib raws theem, txheej txheem txias, thiab txoj kev tiv thaiv:
• Theem:Ib zaug -theem yog tsim nyog rau kev siv nyob hauv tsev, thaum peb -theem yog haum rau lub teeb coj mus muag lossis pej xeem thauj khoom.
• Txoj kev ua kom txias:Roj-immersed transformers muab cua sov dissipation zoo dua thiab siv tau ntev dua; qhuav- hom transformers yog haum rau cov chaw uas muaj kev nyab xeeb hluav taws kub.
• Txoj kev tiv thaiv:Cov hom pa ib txwm xav tau cov fuses sab nraud lossis cov hluav taws xob hauv hluav taws xob, thaum tus kheej - tiv thaiv (CSP) hom tau tsim- hauv cov khoom siv tiv thaiv, ua rau kev teeb tsa yooj yim dua thiab nyab xeeb dua.

 

 

Yuav ua li cas xam qhov yuav tsum tau kVA (muaj peev xwm)? Cov ntsiab lus tseem ceeb xaiv yog dab tsi?

 

• Kwv yees tag nrho cov load:Ntxiv lub zog (watts lossis kilowatts) ntawm txhua yam khoom siv los ntawm lub tshuab hloov pauv.
• Hloov ua lwm yam kVA:kVA=Tag nrho cov load (kW) / Power factor PF
• Ntxiv ib qho kev nyab xeeb:Tawm ib qho ntxiv 10-25% muaj peev xwm rau yav tom ntej nthuav dav, ncov loads, lossis lub cev muaj zog pib tam sim no.

Ncej-mounted transformers tuaj yeem kav ntev li 20-35 xyoo nrog kev saib xyuas kom raug, nyob rau hauv cov xwm txheej zoo. Txawm li cas los xij, hauv kev muaj tiag, lawv lub neej yuav raug txo vim muaj ntau yam laj thawj, feem ntau cov khoom hnav.
Txhawm rau kom muaj kev ua tau zoo, kev saib xyuas tsis tu ncua thiab tshuaj xyuas yog qhov tseem ceeb. Pom zoo txij nkawm zaus:
• Txhua hli:Kev tshuaj xyuas qhov pom ntawm cov roj xau, suab nrov txawv txav, lossis kev puas tsuaj rau lub cev.
• Peb lub hlis twg (txhua 3 lub hlis):Tshawb xyuas bushings, thaiv, thiab cov khoom tiv thaiv sab nraud.
• Ib nrab-ib xyoos (txhua 6 lub hlis):Saib xyuas qhov kub thiab txias nce nyob rau hauv load, thiab xyuas seb corrosion los yog noo noo ingress.
• Txhua xyoo:Rau cov roj- puv transformers, ua cov roj zoo thiab dielectric zog kuaj; rau qhuav- hom transformers, xyuas qhov xwm txheej ntawm rwb thaiv tsev thiab ntxuav qhov chaw.

 

 

Dab tsi engineering thiab kev nyab xeeb Standards yuav tsum tau txiav txim siab thaum lub installation?

 

• Ncej load peev yuav tsum tau raws li qhov yuav tsum tau muaj:Cov ncej hluav taws xob yuav tsum muaj peev xwm txhawb nqa qhov hnyav ntawm lub tshuab hloov pauv, thiab tus ncej yuav tsum muaj suab nrov, tsis muaj rot lossis puas.
• Qhov yuav tsum tau muaj:Kev nyab xeeb nyob deb yuav tsum tau tswj xyuas los ntawm txoj kev, cov tsev, ntoo, thiab lwm qhov chaw kom tiv thaiv kev sib tsoo thiab xyuas kom muaj kev nyab xeeb. Qhov sib nrug tsawg kawg yog feem ntau txiav txim siab los ntawm qib voltage thiab cov cai hauv zos.
• Cov kev cai hauv av kom raug thiab hluav taws xob muaj kev nyab xeeb:Kev txhim kho hauv av thiab kev sib txuas sib txuas yog qhov tseem ceeb los tiv thaiv cov neeg ua haujlwm thiab cov cuab yeej siv, txo qhov kev pheej hmoo ntawm hluav taws xob poob siab, xob laim, thiab overvoltage.
• Ua raws li cov qauv:Kev teeb tsa yuav tsum ua raws li lub tuam txhab hluav taws xob hauv zos thiab cov cai hluav taws xob hauv teb chaws, xws li IEC 60076, IEEE C57 series, thiab ANSI cov qauv.

 

 

Ncej-Mounted vs. Pad-Mounted Transformers: Xaiv qhov twg?

 

Yog tias muaj cov kab hluav taws xob uas twb muaj lawm thiab qhov chaw hauv av yuav tsum tau txais kev cawmdim los yog yuav tsum tau xa mus sai, ncej -mounted transformers yog nyiam vim lawv cov nqi qis dua thiab kev teeb tsa sai dua. Hauv cheeb tsam nroog lossis lwm qhov xwm txheej uas yuav tsum muaj kev nyab xeeb siab, ncoo - mounted transformers yog tsim nyog, muab kev tiv thaiv zoo dua thiab muaj peev xwm loj dua. Kev xaiv ntawm ob yog nyob ntawm hom kab, muaj peev xwm, ib puag ncig, thiab kev xav kom zoo nkauj.

 

 

Dab tsi yog Qhov Kev Ua Phem Ntawm Ncej -Mounted Transformers? Yuav daws teeb meem li cas rau lawv?

 

• Humming lossis vibration:Qhov no feem ntau yog ib lub suab magnetization. Yog hais tias nws yog ntau dhau, xyuas kom xoob cov ntsiab lus los yog kev co.
• Overheating:Feem ntau tshwm sim los ntawm overload los yog qhov cua tsis zoo. Saib xyuas cov load tam sim no, cua sov dissipation, thiab ambient kub.
• Roj to:Rau cov roj-immersed ncej-mounted transformers, xyuas cov gaskets, roj tank, thiab bolts. Kho lossis rov ntxiv cov roj raws li xav tau.
• Nquag tripping:Tej zaum yuav tshwm sim los ntawm overload, luv luv Circuit Court, los yog av txhaum. Txheeb xyuas qhov kev faib khoom thauj khoom thiab kev rwb thaiv tsev.
• Corona lossis arcing:Xyuas cov bushings thiab insulators, ntxuav kom huv si, thiab hloov cov khoom puas.
• Lub cev puas lossis corrosion:Feem ntau tshwm sim los ntawm xob laim tawm tsam, ib puag ncig corrosion, lossis kev cuam tshuam txhua yam. Tshawb xyuas cov dents, xeb, thiab xoob kev sib txuas.
• Kev co txawv txav nyob rau hauv load:Feem ntau yog vim xoob sab hauv. Tighten lossis hloov cov khoom puas, thiab qhov no yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog.

 

 

Dab tsi yog Hom Voltage Levels thiab Regional Differences?

 

Kev faib tawm voltages yog 11kV, 22kV, thiab 33kV ntawm siab-voltage sab, thiab 120/240V lossis 230V ntawm qis-voltage sab. Txawm li cas los xij, cov qauv ntsuas hluav taws xob sib txawv ntawm thaj chaw sib txawv thiab lub teb chaws:
• North America:Lub zog nyob hauv tsev feem ntau yog 120/240V ib zaug-theem, thaum kev lag luam lossis kev lag luam me siv 208V lossis 480V peb-theem.
• Teb ​​chaws Europe:Lub zog nyob hauv tsev feem ntau yog 230V ib zaug -theem, thiab lub zog lag luam / kev lag luam yog 400V peb-theem.
• Asia & Lwm Cheeb Tsam:Cov voltages feem ntau suav nrog 220V / 380V lossis 110V / 220V, nyob ntawm cov kev cai hauv zos.

 

 

Yuav Ua Li Cas Xaiv Tus Ncej Txhim Kho -Mounted Transformer Supplier?

 

Kev xaiv tus neeg muag khoom txhim khu kev qha ua kom lub tshuab hluav taws xob zoo, kev ua tau zoo, thiab ua raws li cov cai. Thaum xaiv ib tus neeg muag khoom, xav txog cov hauv qab no:
