10000 Kva Roj- puv Transformer

Cov10000 kVA Roj Immersed Transformerua raws li lub plawv ntawm lub nroog substations thiab loj -scale industrial fais rings. Ntawm lub peev xwm no, chav tsev yog lub luag haujlwm rau kev txhawb nqa tag nrho cov cheeb tsam lossis cov kab ntau lawm. Yog li ntawd, engineering qhov tseem ceeb hloov los ntawm kev hloov hluav taws xob yooj yim mus raukhoom vaj khoom tsev ntevthiabkev ruaj ntseg yuam kev.

Raws li lub luag haujlwm hnyav -peb theem roj immersed transformer, chav tsev no tau tsim los ua haujlwm tsis tu ncua rau 30+ xyoo. Yuav kom ua tiav qhov no, peb txav dhau txoj kev sib khi txheej txheem thiab siv ib qhoCua Cell (Rubber Bag) Conservator System.

• Lub Logic:Es tsis txhob cia huab cua tiv tauj cov roj ncaj qha (txawm tias los ntawm lub tshuab nqus pa), lub zais zis roj hmab hloov pauv hauv lub conservator "ua pa" huab cua. Cov roj nyob ib puag ncig lub zais zis no, tshuav tag nrho cais tawm ntawm oxygen thiab noo noo. Cov thev naus laus zis no zoo li tshem tawm cov roj oxidation / sludging, txuas ntxiv lub sijhawm ntawm kev saib xyuas roj.

A 10 MVA txhaum tso tawm lub zog loj. Yog li, cov txheej txheem kev nyab xeeb tsis yog - sib tham tau:

• Ob npaug -Float Buchholz Relay:Peb muab chav tsev nrog ob -theem relay. Thawj theem (alarm) pom cov pa roj me me los ntawm kev cuam tshuam cov hluav taws xob qeeb (piv txwv li, ib feem tawm), thaum theem thib ob (trip) tam sim ntawd cais lub transformer thaum muaj roj surge tshwm sim los ntawm luv luv Circuit Court.
• Kev taw qhia PRD:Ib tug loj Pressure Relief Device yog mounted rau ntawm lub tank cover. Tseem ceeb heev, rau ib chav tsev ntawm qhov luaj li cas, nws yog haum nrog adirectional qwstxhawm rau tso cov roj kub kom deb ntawm tus neeg teb xov tooj txoj kev taug kev thaum muaj kev tawg sab hauv.

Ob -theem Buchholz relay ntsia rau ntawm cov yeeb nkab txuas rau

main tank thiab conservator.

Txhawm rau ua kom muaj kev nyab xeeb rau hauv 11kV lossis 33kV network, kev tswj hwm impedance yog qhov tseem ceeb.

• Fault Limitation:Standard 4-5% impedance yog txaus ntshai ntawm 10 MVA vim hais tias lub luv luv-circuit tam sim no yuav siab dhau rau breakers los daws. Chav tsev no yog engineered nrog aStandard impedance ntawm 8.0% rau 9.0%. Qhov no txhob txwm siab dua reactance txwv qhov txhaum tam sim no rau<25kA on the secondary side, matching the standard breaking capacity of medium-voltage switchgear.

• City Grid Substations:Stepping down 33kV kis mus rau 11kV los pub ib lub network ntawm 20-30 me me transformers tawg khiav ri niab nyob rau hauv ib cheeb tsam.
• Hyperscale Data Centers:Siv nyob rau hauv N+1 teeb tsa kom lub zog loj servers, qhov twg lub siab impedance pab txwv arc-flash zog downstream.
• Cement & Steel Cog:Pub lub ntsiab MV switchboard uas powers loj crushers thiab mills (feem ntau yuav tsum tau 6.6kV motors).
