100 kVA Roj-Immersed Distribution Transformer: Specifications and Selection Guide

100 kVA Roj yog dab tsi -Immersed Distribution Transformer?

Lub 100 kVA roj-immersed tis transformer yog peb-theem lossis ib zaug-theem chav tsev nyob rau hauv uas cov tub ntxhais thiab windings yog immersed nyob rau hauv ntxhia insulating roj nyob rau hauv ib tug welded tank. Cov roj ua haujlwm ob zaug ib zaug: nws insulates cov energized windings los ntawm lub tank thiab los ntawm ib leeg, thiab nws nqa cua sov los ntawm cov tub ntxhais thiab coils mus rau lub tank nto, qhov twg nws yog dissipated rau hauv ib puag ncig huab cua. Qhov kev tsim kho no muab tus qauv tsim nws cov yam ntxwv durability: tsis tshua muaj txij nkawm, muaj zog overload kam rau ua, thiab ua haujlwm ruaj khov hauv kev pabcuam sab nraum zoov.

Kev tsim kho thiab kev ua haujlwm

Cov khoom tseem ceeb yog cov tub ntxhais sib nqus, HV thiab LV windings, tawm - Circuit Court lossis ntawm -load tap changer, thiab lub tank sib dhos nrog nws cov fittings. Cov tub ntxhais yog tsim los ntawm cov nplej- taw qhia silicon steel laminations (CRGO), xaiv los ntawm qib kom tsis txhob muaj - load poob qis. Cov windings yog concentric coils ntawm tooj liab los yog aluminium conductor insulated nrog ntawv los yog enamel, qhuav thiab ces impregnated nrog roj kom tshem tawm cov seem seem.

Thaum lub sijhawm ua haujlwm, transformer converts voltage ntawm theem pib thiab theem nrab los ntawm electromagnetic induction. Pawg vector (piv txwv li Dyn11, Yyn0 lossis Dyn5) txiav txim siab theem kev hloov pauv ntawm HV thiab LV systems thiab yuav tsum phim lub network teeb tsa ntawm qhov chaw.

Standard Technical Specifications

Cov lus hauv qab no qhia txog cov kev ntsuas raug rau tus qauv 100 kVA unit. Cov txiaj ntsig tuaj yeem hloov kho rau cov kab lis kev cai hauv zos thiab cov phiaj xwm xav tau.

Tsim nta thiab daim ntawv thov Scope

Cov chav nyob ntawm qhov loj no yog siv rau hauv cov tshuab hluav taws xob, kev lag luam thiab kev lag luam mining, kev thauj mus los, kev sib txuas lus, thiab cov chaw tshawb fawb. Cov txiaj ntsig zoo ntawm cov roj- tus qauv tsim muaj xws li hneev taw me me, kev sib tw thawj tus nqi, muaj zog tiv thaiv huab cua, thiab lub neej ua haujlwm ntev.

Tsawg tsis muaj-load thiab load poob txo tus nqi zog lub neej.

Tsis tshua muaj suab nrov thiab qis ib feem tso tawm txhim kho kev cia siab rau hauv qhov chaw rhiab heev.

Compact dimension yooj yim installation nyob rau hauv ncej-mounted, ncoo-mounted los yog sab hauv tsev cubicle layouts.

Kev saib xyuas yooj yim: niaj hnub kuaj roj qib thiab ntsuas roj raws sijhawm raws li IEC 60422.

Cov Lus Qhia Xaiv thiab Ib puag ncig

Tus qauv tsim cov xwm txheej xav tias qhov ntsuas kub ntawm -45℃rau +40 degree, qhov siab tsis siab tshaj 1000 m, kev sib kis hauv chav kawm III, thiab seismic siv VIII. Yog tias qhov chaw tshaj li cov kev txwv no, tus tsim yuav tsum tau derated los yog ntxiv dag zog, thiab qhov no yuav tsum tau teev nyob rau hauv kev txiav txim specification es tsis kho tom qab xa khoom.

Kev xaiv yuam kev

Xaiv cov vector pawg yam tsis tau kuaj xyuas theem hloov tawm tsam lub network uas twb muaj lawm.

Qhia meej impedance qis dhau rau qhov muaj zog luv luv - theem Circuit Court, uas nce los ntawm - txhaum quab yuam ntawm windings.

Tsis quav ntsej qhov siab tshaj qhov siab tshaj 1000 m, uas ua rau kub nce thiab txo qhov muaj peev xwm thauj khoom.

FAQ

Dab tsi yog qhov txawv ntawm Dyn11 thiab Yyn0?

Dyn11 muaj delta- txuas HV winding thiab lub hnub qub- txuas LV winding nrog 330℃theem hloov chaw; Yyn0 yog lub hnub qub - lub hnub qub nrog 0℃hloov chaw. Dyn11 nyiam nyob rau hauv feem ntau tis network vim hais tias lub delta winding muab ib txoj kev rau triplen harmonics thiab ib tug ruaj khov nruab nrab.

Puas tuaj yeem siv 100 kVA transformer sab nraum zoov?

Yog lawm. Cov roj- puv, welded- tank kev tsim kho nrog huab cua tiv thaiv bushings thiab corrosion- cov xim resistant yog tsim los rau sab nraum zoov ncej lossis lub ncoo mounting, yog tias lub qhov rooj qhib qhov cua thiab tsis ntim tag nrho tsis muaj cua nkag.

Vim li cas impedance voltage tseem ceeb thaum muas 100 kVA transformer?

impedance voltage tswj luv- Circuit Court tam sim no thiab voltage tswj. Qhov qis impedance (piv txwv li 2%) muab cov kev cai voltage zoo dua tab sis siab dua tam sim no; tus nqi yuav tsum tau koom tes nrog lub switchgear thiab kev tiv thaiv chaw.

Copper lossis aluminium windings, uas kuv yuav tsum xaiv?

Copper muab qis load poob, siab dua txhua yam muaj zog thiab me me winding qhov ntev; aluminium txo tus nqi thawj zaug thiab qhov hnyav. Qhov kev xaiv yog nyob ntawm qhov poob peev txiaj ntsig thiab tus neeg yuav khoom tag nrho - tus nqi - ntawm - lub hom phiaj ua tswv.

Yuav ua li cas kuaj ua ntej xa khoom?

Cov kev ntsuam xyuas niaj hnub ntawm IEC 60076 suav nrog kev ua haujlwm winding, kev hloov pauv, tsis muaj -load poob thiab tam sim no, load poob thiab impedance, dielectric test, thiab kub- nce kev pov thawj ntawm ib pawg neeg sawv cev.
