Yuav ua li cas xaiv ib 100kVA Peb-Phase Qhuav-Hom Transformer rau Industrial Distribution Networks

Lub luag haujlwm ntawm 100kVA Qhuav-Hom Transformer hauv Kev Lag Luam

A 100kVA peb-theem qhuav- hom transformer pub me me mus rau nruab nrab kev lag luam loads: rhiav fais fab, machinery mov, tswj systems, teeb pom kev zoo thiab pab faib nyob rau hauv cov nroj tsuag thiab tis chaw nres tsheb. Qhov qhuav- hom kev tsim kho yog xaiv vim nws yog roj-dawb, hluav taws kub- muaj kev nyab xeeb thiab tsim nyog rau kev teeb tsa sab hauv tsev ze rau lub nra, nrog kev saib xyuas qis. Xaiv chav tsev tsis yog ib qho teeb meem ntawm kev sib piv kVA daim duab; lub load profile, voltage theem, ib puag ncig, qauv thiab efficiency tag nrho cov cuam tshuam qhov kawg specification.

Kauj ruam 1: Txhais cov Load Requirements

Qhov pib taw tes yog qhov kev kawm load. Sau cov khoom sib txuas ntawm txhua yam khoom siv uas lub tshuab hloov pauv yuav muab thiab siv qhov sib txawv ntawm qhov tseeb, vim tias cov khoom lag luam tsis tshua muaj khiav ntawm tag nrho cov khoom ib txhij. Qhov ntsuas 100kVA yuav tsum them rau qhov xav tau kev khiav hauj lwm nrog lub taub hau rau luv luv - lub sij hawm peaks, xws li lub cev muaj zog pib thiab tshuab cuab yeej inrush. Lub transformer uas tsis tu ncua overloaded yuav overheat thiab muaj hnub nyoog sai, thaum ib tug hnyav hnyav unit khiav inefficient thiab nqi ntau tshaj qhov tsim nyog. Raws li kev qhia, kev thauj khoom tas mus li hauv 60-85% ntawm qhov ntsuas yog lub hom phiaj suab rau feem ntau cov kev lag luam.

Kuj sau cov xwm txheej ntawm cov khoom thauj: cov khoom siv vuam, sib txawv - ceev tsav thiab rectifiers tsim kev sib haum xeeb uas nce qhov cua sov; yog hais tias cov loads no yeej, qhov kev ntaus nqi siab dua los yog kev sib haum xeeb - qauv tsim yuav tsum tau txiav txim siab.

Kauj Ruam 2: Sib piv cov qib Voltage

Lub transformer yuav tsum phim lub network ntawm ob sab. Paub meej tias thawj qhov hluav taws xob ntawm cov khoom xa tawm (piv txwv li 10kV lossis 6kV) thiab qhov yuav tsum tau muaj qhov nruab nrab voltage (feem ntau 400V / 230V peb-theem plaub-hlau). Pawg vector yuav tsum raug xaiv rau kev npaj av: Dyn11 yog qhov qub qub vim tias nws muab qhov qis -voltage nruab nrab thiab tuav cov khoom tsis sib npaug zoo, thaum Yyn0 siv qhov system earthing xav tau. Tawm- cov kais dej hauv Circuit Court, feem ntau ± 2 x 2.5%, tso cai rau chav tsev kho kom haum rau qhov sib txawv ntawm qhov hluav taws xob hauv zos thaum ua haujlwm.

Kauj Ruam 3: Tshawb xyuas cov xwm txheej ib puag ncig

Kev cob qhia kev lag luam yog qhov xav tau ib puag ncig: kub ambient, plua plav, av noo thiab qee zaus cov pa phem. Yog li cov specification yuav tsum muaj xws li:

Rwb thaiv tsev chav kawm: Chav F (155 degree) lossis Chav H (180 degree) windings nrog qhov ntsuas kub tsim nyog - nce txwv.

Kev tiv thaiv qib: IP20 rau chav hluav taws xob huv, IP23 lossis siab dua rau qhov chaw muaj plua plav lossis ntub dej, lossis lub qhov cua uas muaj qhov sib txuam rau ntawm qhov chaw.

ambient kub thiab altitude derating: siab tshaj 40℃ambient los yog 1000 m qhov siab, cov zis muaj peev xwm txo thiab yuav tsum tau muab xam rau hauv qhov ntsuas.

Lub suab nrov yuav tsum tau: rau kev teeb tsa nyob ze ntawm thaj chaw nyob, qhia meej lub suab txwv kom meej.

Kauj Ruam 4: Txheeb xyuas Cov Qauv Ua Raws Cai

Rau cov khoom siv hauv kev lag luam, kev ua raws li cov qauv lees paub yog qhov yuav tsum tau ua hauv paus. Cov qauv siv tau yog IEC 60076 (power transformers) thiab IEEE C57.12.01 (qhuav-hom transformers), nrog IEC 60076-11 npog cov qhuav- hom kev tsim tshwj xeeb. Cov qauv no txhais cov qib rwb thaiv tsev, qhov kub thiab txias -nce txwv, luv- Circuit Court withstand, suab nrov txwv thiab cov txheej txheem kuaj. Tus neeg muag khoom yuav tsum muab daim ntawv tshaj tawm kev ntsuam xyuas niaj hnub nrog txhua chav tsev, npog cov rwb thaiv tsev tiv thaiv, hloov pauv, winding tsis kam, tsis muaj kev thauj khoom thiab thauj khoom poob, thiab kev ntsuas dielectric, kom qhov kev lees paub tuaj yeem tshawb xyuas cov ntaub ntawv tshaj tawm.

Kauj Ruam 5: Ntsuas Kev Ua Tau Zoo thiab Lub Neej - Tus Nqi Cycle

Kev lag luam transformers yog energized rau lub sij hawm ntev, yog li tsis muaj -load poob (hlau poob) yog noj tsis tu ncua. Kev tsim qauv siab -kev ua tau zoo nrog qis- poob silicon steel core thiab tooj liab windings txo ob qho tib si tsis muaj- load thiab load poob, txiav nqi hluav taws xob thiab cov pa roj carbon emissions tshaj 20-30 xyoo lub neej ntawm chav tsev. Thaum sib piv cov lus hais, ntsuas tus nqi peev ntawm qhov poob es tsis yog tus nqi yuav khoom ib leeg; ib qho me me thawj-nqi txuag tau nrawm dua los ntawm kev poob siab dua.

Tej Parameter Table

Cov nqi poob yuav tsum tau teev los ntawm cov chaw tsim khoom rau cov chav tsim qauv tshwj xeeb thiab txheeb xyuas los ntawm kev xeem; rau chav kawm 100kVA, ib txwm tsis muaj -load poob yog nyob rau hauv thaj tsam ntawm 200-400 W thiab load poob nyob rau hauv thaj tsam ntawm 1500-2500 W nyob ntawm seb qhov ua tau zoo ntawm chav kawm, thiab daim ntawv tshaj tawm kev xeem yog cov ntaub ntawv pov thawj.

Installation thiab Commissioning Notes

Lub transformer yuav tsum tau muab tso rau hauv ib lub qhov cua nrog clearance txaus nyob ib ncig ntawm lub enclosure, ntawm ib theem, kev co - dawb foundation. Kev txiav cable yuav tsum tau ua nrog qhov tseeb torque, thiab kev sib txuas hauv av yuav tsum raug txheeb xyuas. Ua ntej energising, xyuas qhov kais teeb tsa tiv thaiv qhov ntsuas qhov ntsuas hluav taws xob, thiab tom qab lub zog, sau qhov tsis muaj -load nyeem ntawv thiab ntsuas kub. Rau cov nroj tsuag uas muaj cov ntsiab lus siab sib haum xeeb, thawj qhov kev tshawb fawb thermographic nyob rau hauv kev thauj khoom raug pom zoo kom paub meej tias qhov cua sov yog nyob rau hauv qhov txwv.

Cov lus nug nquag

Q1. 100kVA transformer muaj peev xwm thauj khoom ntau npaum li cas?Nws tuaj yeem xa 100 kVA tsis tu ncua ntawm nws cov kev ntsuas ntsuas, tab sis qhov tseeb siv tau yog nyob ntawm lub zog thauj khoom, qhov ntsuas kub thiab qhov tso cai tshaj. Lub hom phiaj ua haujlwm tas mus li yog 60-85% ntawm kev ntsuas rau kev lag luam.

Q2. Dab tsi yog qhov txawv ntawm IP20 thiab IP23 enclosures?IP20 tiv thaiv cov khoom loj dua 12 hli thiab tsis muaj dej tiv thaiv; nws suits huv chav tsev. IP23 ntxiv kev tiv thaiv tiv thaiv cov dej txau, ua rau nws haum rau qhov chaw ntub dej lossis chaw ntxhua khaub ncaws.

Q3. Vim li cas Dyn11 vector pawg yog lub neej ntawd?Dyn11 muab qhov nruab nrab ntawm qhov qis -voltage sab rau ib zaug -theem loads, muaj thib peb- harmonic tam sim no nyob rau hauv lub delta thawj, thiab tuav unbalance loading zoo dua Yyn0, uas yog ib qho yuav tsum tau muaj nyob rau hauv industrial faib.

Q4. Puas qhuav- hom transformers xav tau ib qho overload relay?Kev tiv thaiv overload yog muab los ntawm cov hluav taws xob sab sauv lossis cov fuses thiab los ntawm kev ntsuas qhov kub thiab txias.
