2. Cov xov hlau: Cov khoom siv hluav taws xob uas tau tsim tshwj xeeb
Cov windings raug teeb tsa kom zoo kom sib npaug qhov faib hluav taws xob thiab kev ua haujlwm zoo:

Cov Hluav Taws Xob Siab (HV): Feem ntau yog qhwv nrog cov hlau tooj liab lossis txhuas, rwb thaiv tsev nrog epoxy-resin lossis Nomex, thiab muab tso rau sab nraum cov hluav taws xob qis (LV) rau qhov ntsuas hluav taws xob zoo tshaj plaws.
LV Windings: Cov windings me me, muab tso ze rau lub hauv paus kom txo qhov xau reactance.
Kev tsim kho tshiab:

Cov Hlau Nplaum LV Uas Muaj Ntawv Nyiaj: Txo cov zog luv luv thaum muaj xwm txheej ib ntus, raws li tau lees paub los ntawm kev tshuaj xyuas cov khoom kawg (FEA) hauv.
Kev Teeb tsa Hloov Pauv Theem: Ua kom muaj kev sib raug zoo nrog cov kab ke ntse uas xav tau kev tswj hwm hluav taws xob dynamic.

3. Cov Tshuab Txias: Kev Tswj Xyuas Kev Ua Haujlwm Zoo
Cov transformers peb-theem pad-mounted siv cov txheej txheem txias siab heev:

​ONAN (Roj-Cua Ntuj-Ntuj): Kev sib hloov huab cua ntuj ua rau cov roj transformer ncig thoob plaws hauv cov radiators.
ONAF (Roj-Natural Cua-Yuam): Cov kiv cua ua kom cua ntsawj ntxiv rau qhov muaj peev xwm thauj khoom ntau dua, zoo tagnrho rau cov chaw lag luam.
Kev Kawm Txog Cov Ntaub Ntawv:
Eaton's VFI (Vacuum Fault Interrupter) transformers sib xyaw ua ke cov chaw kaw nrog lub tshuab tawg pom, ua kom muaj kev saib xyuas zoo thiab ua raws li IEEE 1584 arc-flash cov qauv.

4. Cov yam ntxwv tiv thaiv: Kev nyab xeeb ua ntej
Cov Li Qub Txo Siab: Tiv thaiv kev kub siab dhau los ntawm cov kab hluav taws xob sab hauv.
Buchholz Relay: Tshawb pom cov pa roj sib sau ua ke los ntawm kev puas tsuaj ntawm cov rwb thaiv tsev, tiv thaiv kev puas tsuaj loj heev.
Kev Saib Xyuas Ntse: Cov qauv siv IoT (piv txwv li, Eaton's PRCLF-series) muab cov ntaub ntawv tiag tiag txog qhov kub thiab txias, qhov hnyav, thiab kev noj qab haus huv ntawm kev rwb thaiv tsev los ntawm SCADA systems.

5. Kev Tsim Qauv: Kev Ruaj Khoov Sib Tw Nrog Kev Me Me
Lub thawv tiv taus xeb: Cov hlau galvanized kub lossis cov ntaub ntawv sib xyaw ua ke tiv taus qhov chaw ib puag ncig hnyav.
Kev Txhawb Nqa Av Qeeg: Cov brackets txhawb nqa ua kom ruaj khov hauv cov cheeb tsam uas muaj av qeeg.
Kev Sib Dhos Modular: Ua kom yooj yim rau kev teeb tsa thiab kev hloov kho yav tom ntej, tseem ceeb rau cov haujlwm hluav taws xob rov ua dua tshiab.

Cov Ntawv Thov Tsav Tsheb Tshiab
Kev Sib Koom Tes Zog Rov Ua Dua Tshiab: Cov hloov pauv theem siab rau 5MW+ lub hnub ci/cua ua liaj ua teb siv cov tshuab nqus tsev los tswj cov hluav taws xob muaj hluav taws xob ntau.
Cov Chaw Khaws Cov Ntaub Ntawv: Cov qauv tsim me me, suab nrov tsawg ua kom muaj zog tsis tu ncua nrog kev tswj hwm hluav taws xob ± 1%.
Kev Siv Tshuab Hauv Kev Lag Luam: Kev ntsuas impedance tshwj xeeb (piv txwv li, 5.75%) ua kom lub zog zoo rau cov tshuab rhiab heev.

Vim li cas ho xaiv peb cov Transformers peb theem Pad-Mounted?
Kev Ua Haujlwm Zoo: >99% kev ua haujlwm zoo thaum lub sijhawm puv ntoob, ua raws li IEC 60076 cov qauv.
Kev Nyab Xeeb: Cov thawv uas tiv taus arc txo cov zog tshwm sim kom tsawg dua 1.2 cal/cm² (NFPA 80).
Kev Kho Kom Haum: Muaj nyob rau hauv 10kV–34.5kV voltage chav kawm thiab 50–5000kVA kev ntsuas.

Lub transformer peb-theem pad-mounted lub architecture sab hauv sib xyaw ua ke precision engineering nrog cov yam ntxwv kev nyab xeeb tshiab, ua rau nws yog lub hauv paus ntawm cov tshuab fais fab niaj hnub. Txawm hais tias koj tab tom muab hluav taws xob rau lub Hoobkas ntse lossis lub chaw ua haujlwm cua nyob deb, peb cov kev daws teeb meem muab kev ntseeg siab thiab kev hloov pauv tsis tau.
