160kVA Qhuav-Type Distribution Transformer: Specifications and Applications

Dab tsi yog Dry -Hom Distribution Transformer?

Lub tshuab ziab khaub ncaws- hom kev faib tawm yog lub tshuab hluav taws xob hloov hluav taws xob uas ua kom txias thiab ua kom tsis muaj kua, siv huab cua los yog yuam kev ua pa es tsis txhob siv roj. Chav kawm 160kVA yog qhov nruab nrab- chav tsev muaj peev xwm dav siv los nqis qis 10 kV lossis 20 kV kab hluav taws xob mus rau 0.4 kV qis-voltage mov rau kev lag luam thiab kev lag luam kawg- cov neeg siv. Vim tias tsis muaj roj, lub tshuab hluav taws xob nthuav tawm tsis muaj hluav taws kub lossis nchuav, uas ua rau nws tsim nyog rau kev teeb tsa sab hauv tsev, hauv nroog thiab cov chaw uas muaj cov lej hluav taws kub nruj. Cov kev teeb tsa ib txwm yog peb-theem, 50/60 Hz, nrog thawj ntawm 10 kV lossis 20 kV thiab theem nrab ntawm 0.4 kV / 0.23 kV, tsim raws li IEC 60076 thiab cov qauv thoob ntiaj teb.

Cov yam ntxwv tseem ceeb

Roj-kev ua haujlwm pub dawb: tsis muaj kuab paug, tsis muaj roj ntim, tsis muaj qhov txaus ntshai, thiab txo kev cuam tshuam ib puag ncig piv nrog cov roj- raus dej.

Compact thiab robust tsim: lub encapsulated windings thiab cov khoom rwb thaiv tsev tso cai rau ib tug me me hneev taw, uas yog ib qho tseem ceeb rau sab hauv tsev faib chav tsev thiab substations hauv nroog.

High-efficiency core: 0.23 hli qis-tso lis-qhia silicon steel core tsis muaj-load poob qis; siab -conductivity oxygen-dawb tooj liab windings ua kom cov khoom poob qis.

Tsis tshua muaj suab nrov thiab kev vibration: cov tub ntxhais thiab winding los ua ke yog damped, ua hauj lwm suab nrov ntawm li 55 dB(A) los yog qis dua hauv huab cua-natural hom.

Cov dej noo-tiv taus thiab hluav taws kub- pov thawj kev tsim kho: cov txheej txheem rwb thaiv tsev tiv taus qhov chaw ntub dej zoo dua li qhib qhov txhab tsim, thiab tsis muaj cov roj hluav taws kub hnyiab.

Qhuav-Hom vs Roj-Immered: Kev xaiv xaiv

Qhuav- hom transformers yog qhov nyiam qhov kev nyab xeeb hluav taws xob, kev teeb tsa sab hauv tsev, kev saib xyuas tsis zoo thiab ib puag ncig cov cai tswj hwm qhov kev txiav txim siab, thiab qhov twg lub transformer yuav tsum nyob ze rau ntawm qhov load. Roj-immersed transformers feem ntau pheej yig dua ntawm qhov kev ntaus nqi loj, muaj kev coj tus cwj pwm zoo dua, thiab yog tus qauv xaiv rau sab nraum zoov ncej thiab hauv av mounting. Rau ib daim ntawv thov 160kVA hauv ib lub tsev, chav tsev qhuav- feem ntau yog qhov zoo dua; rau ib qho kev faib tawm sab nraum zoov, cov roj- cov roj puv tuaj yeem ua tau zoo dua.

Installation thiab Maintenance Notes

Qhuav- hom transformers yog qhov tseem ceeb ntawm kev saib xyuas- pub dawb sib nrug los ntawm kev tu txhua lub sijhawm ntawm txoj kev ua pa thiab tshuaj xyuas cov kev sib txuas. Txhim kho lub tsev nyob rau hauv ib lub qhov dej - chav cua qhov cua, hwm qhov tsawg kawg nkaus clearances rau phab ntsa thiab lwm yam khoom siv, thiab xyuas kom meej hauv pem teb tuaj yeem txhawb nqa qhov hnyav. Ntawm qhov siab tshaj 1,000 m, qhov muaj peev xwm ua kom txias qis, yog li kev thauj khoom yuav tsum tau derated raws li IEC 60076-11 kev taw qhia.

FAQ

Dab tsi yog qhov txawv ntawm qhov qhuav - hom thiab roj -immersed transformer ntawm 160kVA?

Ib tug qhuav- hom transformer siv huab cua los yog encapsulated cov khoom rwb thaiv tsev thiab tsis muaj hluav taws kub los yog roj- muaj feem cuam tshuam, ua rau nws haum rau siv sab hauv tsev. Ib lub roj- raus dej siv cov roj insulating kom txias thiab rwb thaiv tsev, yog ntau compact ib kVA ntawm qee qhov kev ntaus nqi thiab yog tsim los rau kev teeb tsa sab nraum zoov. Qhuav- hom chav kuj tseem muaj qhov xav tau kev saib xyuas qis dua tab sis feem ntau kim dua ntawm qhov ntsuas tib yam.

Puas yog 160kVA qhuav-hom transformer tuaj yeem ntsia sab nraum zoov?

Yog lawm, yog tias nws tau muab nrog cov ntaub ntawv tiv thaiv huab cua tsim nyog thiab qib kev tiv thaiv xws li IP54 lossis siab dua. Txawm li cas los xij, feem ntau tus qauv 160kVA qhuav- hom units yog tsim los rau kev teeb tsa sab hauv tsev, yog li paub meej qhov kev ntsuas ib puag ncig ua ntej tso chav nyob sab nraum zoov.

Dab tsi yog tag nrho -load tam sim no ntawm 160kVA qhuav- hom transformer ntawm 0.4 kV?

Rau peb -theem chav tsev nrog 0.4 kV theem nrab, tag nrho -load kab tam sim no yog kwv yees li 160,000 / (1.732 x 400)=231 A. Ntawm 10 kV thawj sab, qhov tam sim no yog kwv yees li 9.2 A.

Lub suab nrov npaum li cas yog 160kVA qhuav -hom transformer ua?

Ib chav tsev txheem ua haujlwm ntawm 55 dB(A) hauv huab cua -natural hom, ntsuas ntawm 1 m nrug. Nrog rau qhov zoo tshaj plaws damping, lub suab nrov tuaj yeem txo mus rau 50 dB(A) lossis qis dua rau lub suab nrov - qhov chaw nkag siab.

Dab tsi yog qhov kev pab cuam lub neej ntawm qhuav -hom transformer?

Nrog rau kev txhim kho kom zoo, qhov cua thiab kev tshuaj xyuas ib ntus, lub tshuab ziab khaub ncaws qhuav -hom transformer feem ntau ua haujlwm rau 20-30 xyoo. Cov txheej txheem rwb thaiv tsev yog qhov kev laus ntawm cov khoom siv: ua kom lub qhov cua kub tsis pub dhau F-chav kawm txwv thiab tsis txhob muaj kev cuam tshuam ntau dhau yog qhov tseem ceeb uas txiav txim siab lub neej tiag tiag.

Puas yog lub tshuab hluav taws xob qhuav qhuav puas xav tau Buchholz relay lossis kuaj roj?

Tsis yog vim tsis muaj roj, tsis muaj Buchholz relay thiab tsis muaj roj sampling. Kev ntsuas kub ntawm PT100 sensors thiab lub tshuab ntsuas kub cua hloov pauv cov roj- raws li kev tiv thaiv thiab saib xyuas cov haujlwm.
