Seamless Integration pib nrog txoj cai fais fab Transformer
01 General
1.1 Project Description
1000kVA fais fab transformer tau xa mus rau South Africa hauv 2025. Lub zog ntsuas ntawm lub transformer yog 1000 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 66 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 11 kV, lawv tsim ib pawg vector ntawm Dyn11.
Lub tshuab hluav taws xob ua kom muaj cua sov kom zoo, nrog rau qhov siab tshaj plaws cua kub nce ntawm 60℃thiab sab saum toj roj kub nce ntawm 55℃kom tswj tau qhov kev ua haujlwm zoo.
Nrog rau qhov impedance ntawm 5% thiab impressive efficiency- mus txog 98.789% ntawm tag nrho cov load (1.0 PF) thiab 98.49% ntawm 0.8 PF (ob qho tib si ntsuas ntawm 75 degree)-nws txo lub zog poob thaum lub zog xa mus. Nruab nrog qhov tseem ceeb ntawm kev nyab xeeb thiab kev saib xyuas cov khoom, suav nrog Buchholz relay rau kev kuaj xyuas qhov txhaum, roj thiab qhov ntsuas kub ntawm qhov ntsuas kub (nrog rau kev txhawb nqa thiab 4-20mA / RS485 tso zis), roj qib ntsuas, thiab lub siab nyem li qub, nws muaj kev tiv thaiv kev tiv thaiv overheating, roj to, thiab siab dhau. Cov khoom siv ntxiv xws li cov khoom siv hluav taws xob off-circuit changers, ntws / ntim cov li qub, cov khoom siv roj sampling, thiab lifting lugs txhim kho kev ua haujlwm yooj yim thiab kev saib xyuas yooj yim.
Qhov hnyav 7700kg tag nrho (kev thauj mus los hnyav: 5700kg) nrog lub tank ruaj khov thiab cov khoom siv tsim, qhov kev hloov pauv no yog tsim los rau kev ntseeg siab hauv kev lag luam hluav taws xob thiab kev sib kis ntawm kab sib chaws. Nws koom ua ke cov kev cai meej (1.07% ntawm 1.0 PF, 3.78% ntawm 0.8 PF tag nrho load) thiab ntau yam kev nyab xeeb kev nyab xeeb, ua rau nws muaj kev cia siab rau qhov nruab nrab - rau - siab voltage zog hloov xav tau.

02 Kev tsim khoom
2.1 LV TSI
Cov plooj (porcelain bushing) ntawm lub tshuab hloov hluav taws xob qis- sab hluav taws xob muab qhov hluav taws xob tawm rau LV winding kev sib txuas. Cov qauv tsim qauv no muaj qhov siab - lub zog ceramic insulator paub txog kev ua haujlwm zoo thiab huab cua tsis kam. Nws nyob hauv nruab nrab tus neeg xyuas pib thiab ua haujlwm tseem ceeb hauv kev sib txuas, ua kom muaj kev nyab xeeb hluav taws xob cais tawm ntawm lub tank thiab qhov chaw txuas txhim khu kev qha rau sab nraud busbars lossis cables.
2.2 HV Bushing
Cov plooj (porcelain bushing) nyob rau ntawm lub transformer siab -voltage sab muab lub ntsiab lus tawm insulated rau HV winding txuas. Tsim los nrog lub siab - lub zog ceramic insulator, nws muaj qhov ntev ntawm kev nkag mus thiab cov txheej txheem rwb thaiv tsev ntau dua kom tiv taus hluav taws xob ntau dua. Nws lub luag haujlwm tseem ceeb yog los xyuas kom muaj kev sib cais muaj kev nyab xeeb ntawm qhov hluav taws xob siab los ntawm lub tank hauv av thiab muab qhov kev sib txuas ruaj khov rau kev sib txuas HV sab nraud. Lub glazed nto muaj cov pa phem zoo heev rau kev pabcuam sab nraum zoov.
2.3 Tswj Box
Lub thawv tswj, feem ntau yog ib qho kev tiv thaiv huab cua mounted ntawm lub tank transformer, lub tsev tiv thaiv, saib xyuas, thiab tswj cov khoom siv. Nws muaj cov khoom xws li tiv thaiv relays, kais changer tswj, kub thiab roj qib ntsuas, thiab lub tswb hu. Nws lub luag haujlwm tseem ceeb yog muab lub hauv paus, nkag mus tau rau hauv kev tswj hwm kev ua haujlwm ntawm lub tshuab hluav taws xob, tshaj tawm cov lus ceeb toom rau cov xwm txheej txawv txav, thiab ua kom yooj yim saib xyuas thiab tswj cov chaw taws teeb.
2.4 BCT Junction Box
BCT (Bushing Current Transformer) hlws ris lub thawv yog ib lub thawv ntim khoom nyob ze ntawm lub tshuab hloov pauv lub bushings. Nws nyob rau theem nrab terminals ntawm tam sim no transformers uas yog encapsulated nyob rau hauv lub bushing rwb thaiv tsev. Lub thawv no muab cov kev tiv thaiv thiab nkag mus tau rau kev sib txuas lus rau kev taw qhia cov cuab yeej - theem tam sim no cov teeb liab mus rau lwm qhov ntsuas, tiv thaiv relays, thiab cov cuab yeej saib xyuas.
2.5 Winding Thermometer
Lub ntsuas cua winding ntsuas qhov ntsuas kub ntawm qhov kub tshaj plaws nyob rau hauv lub transformer winding. Nws muaj lub teeb pom kev zoo tso rau hauv lub hnab ntim siab nyob ze rau sab saum toj ntawm lub winding, txuas ntawm lub raj capillary mus rau qhov chaw taws teeb dial gauge feem ntau ntsia ntawm lub thawv tswj. Qhov kev ntsuas ncaj qha no yog qhov tseem ceeb rau kev tiv thaiv thermal, ua kom muaj kev tswj hwm kev thauj khoom, tshaj tawm - lub tswb ntsuas kub, thiab pib tswj cov cua txias kom ntseeg tau tias muaj kev nyab xeeb thiab txhim khu kev qha transformer.
2.6 Buchholz Relay
Lub Buchholz relay yog cov pa roj- ua kom muaj kev tiv thaiv cov cuab yeej txuas rau hauv cov yeeb nkab roj ntawm lub transformer lub ntsiab tank thiab cov neeg saib xyuas. Nws pom qhov ua txhaum ntawm sab hauv los ntawm kev teb rau cov khoom sib xyaw ntawm cov pa roj los ntawm kev cuam tshuam cov hluav taws xob qeeb (ua rau lub tswb nrov) los yog cov roj surge tshwm sim los ntawm qhov ua txhaum loj (ua rau kev mus ncig tam sim). Qhov no muab kev ceeb toom tseem ceeb thaum ntxov thiab kev tiv thaiv tiv thaiv tus neeg raug tsim txom thiab kev ua txhaum loj sab hauv.
03 Kev Xeem
Frequency Response Analysis (FRA) yog cov txheej txheem kuaj mob uas ntsuas qhov kev ntseeg ntawm cov tshuab hluav taws xob hloov pauv. Los ntawm kev txhaj tshuaj qis -voltage sinusoidal teeb liab hla ntau zaus ntawm ib lub davhlau ya nyob twg thiab ntsuas cov lus teb ntawm lwm qhov, nws tsim qhov tshwj xeeb "tus ntiv tes" ntawm winding txoj haujlwm hloov pauv. Qhov sib txawv ntawm qhov kos npe no los ntawm lub hauv paus yav dhau los los yog tus muam winding qhia tias muaj peev xwm ua kom puas tsuaj, xws li deformation, hloov chaw, los yog xoob cov khoom nyob rau hauv cov tub ntxhais thiab windings.
