S11 125 kVA Peb-Phase Roj-Immersed Fais Fab Transformer: Tsis Siv Neeg thiab Kev Xaiv

S11 Series Txheej txheem cej luam

Lub S11 series yog ib tsev neeg ntawm peb -theem roj- immersed tis transformers npog 30 mus rau 2500 kVA ntawm thawj voltage chav kawm txog 20 kV, nrog rau theem nrab voltage ntawm 0.4 kV. S11 poob qib sawv cev rau cov kauj ruam hloov hauv kev ua tau zoo tshaj li yav dhau los xws li S9, ua tiav los ntawm qhov qis dua - poob core thiab optimized windings. Tsim, kuaj, thiab ntsuas qhov poob ua raws IEC 60076 thiab GB 1094.

Faj seeb: qhov khiav ceev hauv kab impedance txhais tau hais tias tus nqi raug kho raws li qhov project specification raws li IEC 60076-5; cov txiaj ntsig tau pom (5.5% ntawm 50 kVA thiab 6% ntawm 630 kVA) yog cov piv txwv rau cov koob no.

Tsim nta

Kev poob qis: S11 poob qib txiav ob qho tib si tsis muaj- thauj khoom thiab thauj khoom poob txheeb ze rau yav dhau los.

Tsawg suab nrov: optimized core pob qij txha thiab clamping kom audible suab qis.

Tsawg ib feem tawm: tswj cov txheej txheem winding thiab ziab kom zoo dua dielectric stability.

Compact thiab lub teeb: refined kev tsim kho txo ​​qhov loj thiab qhov hnyav rau tib qhov kev ntsuas.

Ib puag ncig tej yam kev mob

Tus qauv tsim tsim nyog rau cov xwm txheej hauv qab no:

Qhov kub siab tshaj plaws ambient: +40 C

ambient kub: -25 C

Qhov siab: qis dua 1000 m (derating siv saum toj no)

Lub hli nruab nrab cov av noo: 90% ntawm 20 C

Kev teeb tsa: sab hauv tsev lossis chaw tiv thaiv yam tsis muaj hluav taws kub, tawg, muaj kuab paug hnyav, tshuaj lom neeg corrosion, lossis kev co hnyav

Voltage Regulation thiab Tapping

Rau cov chav nyob nrog rau ntawm -load kais hloov pauv, qhov siab -voltage sab tuaj yeem muab kev tswj hwm ntau ntawm ± 5% lossis ± 2 x 2.5%. Rau off- Circuit Court hloov pauv, cov kais dej tau teeb tsa ntawm lub Hoobkas lossis hloov tsuas yog thaum lub tsev yog de-energized.

Cov cheeb tsam thov

S11 series yog siv rau hauv cov chaw tsim hluav taws xob, cov chaw tsim hluav taws xob, cov chaw lag luam loj thiab cov chaw mining, cov nroj tsuag petrochemical, cov chaw lag luam, thiab hauv nroog thiab nyob deb nroog.

Cov lus nug nquag

Lub npe S11 txhais li cas?

S qhia peb -theem roj- raus dej, thiab 11 txheeb xyuas qhov poob ntawm koob; nws ua tau zoo dua li S9 thiab yav dhau los series.

Dab tsi yog qhov txawv ntawm tsis muaj -load poob thiab load poob?

Tsis muaj-load poob yog cov hlau poob tam sim no thaum twg lub transformer yog energized; load poob yog tooj liab poob uas loj hlob nrog lub square ntawm lub load tam sim no.

S11-125/20 tuaj yeem ua haujlwm ntawm 0.4 kV ntawm sab qis?

Yog, qhov thib ob yog 0.4 kV; tus qauv tooj yog hais txog 20 kV thawj chav kawm.

Dab tsi kais ntau yog muaj?

Tawm- cov chav nyob hauv Circuit Court feem ntau muab ± 5% lossis ± 2 x 2.5% ntawm qhov siab -voltage sab; ntawm -load units muab tib qhov sib txawv nrog kev hloov hauv qab load.

Qhov siab puas cuam tshuam qhov ntsuas?

Yog lawm, saum toj no 1000 m cov huab cua ceev thiab txias txo, yog li lub transformer yog derated los yog teev nrog ib tug ntau dua txias margin.

Yuav ua li cas yog impedance voltage xaiv?

Impedance cuam tshuam ob qho tib si luv- Circuit Court tam sim no thiab voltage tswj; Nws raug xaiv raws li IEC 60076-5 thiab cov kev tshawb fawb hauv network, feem ntau 4-6% rau kev faib khoom hloov pauv.
