250 Kva Qhuav Hom Transformer

Cov250 kVA Qhuav Hom Transformerua raws li tus qauv niaj hnub rau kev lag luam lub tsev fais fab, ua kom muaj txiaj ntsig zoo ntawm qhov sib txawv ntawm cov cuab yeej cuab tam thiab cov kev cai IEC tam sim no.

Hauv ntau thaj tsam keeb kwm ua raws li NEMA cov qauv, cov225 kva qhuav hom transformeryog tus default specification. Peb cov qauv 250 kVA ua haujlwm raws li kev ntsuas ncaj qha (IEC) hloov. Los ntawm kev xaiv chav tsev no, cov neeg saib xyuas chaw tau nce kwv yees li11% ntxiv zog txuas ntxiv muaj peev xwmnyob rau hauv tib lub installation hneev taw. Lub taub hau ntxiv no yog qhov muaj txiaj ntsig zoo rau kev tuav "kev nkag siab" ntawm cov khoom siv hluav taws xob ntxiv hauv lub tsev lub neej yam tsis tas yuav tsum tau hloov pauv hloov pauv thaum ntxov.

Thaum ntsuas qhov sib txawvhom ntawm transformerrau kev siv sab hauv tsev, qhov kev txiav txim siab feem ntau yog tsom rau kev tswj hwm kev pheej hmoo hluav taws. Raws li qhov tseebcua insulated qhuav hom, chav tsev no siv cov huab cua nyob ib puag ncig yog thawj qhov cua txias thiab dielectric nruab nrab ntawm cov windings, txhawb los ntawm siab - kub rwb thaiv tsev (Nomex lossis Aramid ntawv).

• Zero Hluav Taws Load:Tsis zoo li cov roj roj uas muaj ntau pua litres ntawm cov roj hluav taws xob, cov cua no - insulated tsim tsim yuav luag tsis muaj hluav taws. Nws tshem tawm qhov xav tau ntawm cov hluav taws tua hluav taws tua hluav taws los yog cov phab ntsa tawg hauv chav hluav taws xob, txo cov nqi hluav taws xob hauv pej xeem.
• Kev Tiv Thaiv Flashover:Qhov sib nrug ntawm HV thiab LV coils yog nruj me ntsis ntsuas los tiv thaiv flashovers los ntawm huab cua sib txawv, txawm tias nyob rau hauv cov huab cua ntub, tswj kev muaj peev xwm Impulse Withstand siab (BIL).

Txij li thaum lub active feem nyob rau hauv cov huab cua ncig, lub sab nraud enclosure plays lub luag hauj lwm tseem ceeb.

• IP23 Txuj:Peb feem ntau yog lub tsev ntawm 250 kVA core thiab coil nyob rau hauv ib lub ventilated steel enclosure ntsuas ntawmIP23.
• Lub cev Barrier:Qhov kev ntsuas no ua kom ntseeg tau tias thaum cua txias tuaj yeem nkag mus (ntawm a<60° angle), the unit is protected against vertical water drips (e.g., from ceiling condensation) and the ingress of solid objects larger than 12mm (preventing rodents or accidental finger contact with live parts).

Kaw-up ntawm IP23 ventilated steel enclosure tiv thaiv 250 kVA

qhuav hom transformer coils.

250 kVA qhuav hom transformer core thiab coil tag nrho sib sau ua ke hauv kev tiv thaiv hlau thaiv.

• Kev Kawm Txuj Ci:Kev txhim kho hauv tsev kawm ntawv lossis tsev kawm qib siab uas cov cai tswj hwm kev nyab xeeb nruj me ntsis txwv tsis pub ua kua - puv transformers sab hauv tsev.
• Office Retrofits:Hloov kev laus225 kva qhuav hom transformercov chav nyob hauv cov chaw ua haujlwm qub nrog kev ua kom zoo dua qub, siab dua - chav tsev muaj peev xwm.
• Lub teeb Manufacturing:Fais fab sib dhos kab qhov twg lub load profile yog khov kho thiab tsis - polluting.
