Master Node ntawm Distribution Networks
Cov5000 kVA Roj Immersed Transformerua lub zog tseem ceeb rau cov chaw ua lag luam loj -cov chaw ua si, tsev kho mob, thiab hauv cheeb tsam substations. Ntawm lub peev xwm no, lub tsev txuas txuas qhov sib txawv ntawm qhov siab -voltage kis tau tus mob thiab kev faib tawm hauv zos, ua raws li "Master" chav tsev uas pub ntau lub tshuab hluav taws xob qis qis.
Thaum functionally categorized li ib tug lojroj immersed faib transformer, nws engineering aligns ntau ze nrog lub hwj chim transformer qauv. Nws yog tsim los tswj cov txheej txheem load complex qhov twg voltage stability yog qhov tseem ceeb.
Active Voltage Stabilization (OLTC)
Ntawm 5 MVA, ib qho yooj yim tsau kais qhov chaw tsis tshua muaj txaus los tswj cov kab sib chaws hloov pauv txhua hnub. Hloov chaw ntawm tus qauv tawm- cov kais dej hauv Circuit Court, chav tsev no yog tsim los nrog lub zogNtawm -Load Tap Changer (OLTC).
Qhov no mechanism tso cai rau lub transformer rau lub cev hloov kais dej nyob rau hauv tag nrho cov load tej yam kev mob yam tsis muaj cuam tshuam lub hwj chim mov. Thaum txuas nrog lub vaj huam sib luag sab nraud (AVR), lub tshuab hloov hluav taws xob nquag suav qhov hluav taws xob sags tshwm sim los ntawm kev ua haujlwm siab tshaj plaws. Nws hloov kho qhov sib piv (feem ntau hla ± 10% ntau) kom ntseeg tau tias qhov hluav taws xob theem nrab tseem nyob hauv pob zeb- khov kho, tiv thaiv cov khoom siv qis qis los ntawm kev mus ncig undervoltage.

Kev Npaj Kev Tiv Thaiv Sib Txawv
Kev tiv thaiv lub siab - cov cuab tam peev zoo li 5 MVA transformer yuav tsum tau kuaj xyuas qhov nrawm nrawm dua li cov qauv fuses lossis cov khoom tawg tuaj yeem muab tau.
Peb tsim lub tank kom haumturret -mounted Tam sim no Transformers (CTs)ncaj qha rau hauv HV thiab LV bushing turrets. Qhov kev teeb tsa no yog qhov tseem ceeb rau kev sivDifferential Protection Schemes. Los ntawm kev saib xyuas qhov sib npaug tam sim no ntawm kev tawm tswv yim thiab cov zis, lub kaw lus tuaj yeem txheeb xyuas thiab cais cov microscopic sab hauv winding faults (xws li tig-rau-tig luv) hauv milliseconds- ntev ua ntej lawv nce mus rau hauv kev puas tsuaj loj tank.

Installation & Application Context
- Industrial Main Substation:Siv 33kV lub zog los ntawm daim phiaj thiab nqis mus rau 11kV lossis 6.6kV los pub ib lub nplhaib ntawm cov hloov pauv me me thoob plaws hauv pem teb.
- Mining Heavy Khoom:Fais fab loj draglines los yog crushers qhov twg pib voltage poob yuav tsum tau nquag them los ntawm OLTC.
- Cheeb Tsam Hluav Taws Xob:Ua raws li zonal feeder rau ib lub zos nyob, muab roughly3,000 txog 4,000 tsev.
5000 kVA roj immersed transformer ntsia rau sab nraum zoov
industrial main substation.
FAQ
Q1: Dab tsi voltage configurations muaj rau 5000 kVA transformer?
Tus qauv teeb tsa yog 33kV thawj / 11kV theem nrab (IEC 60076) lossis 35kV thawj / 11kV theem nrab (GB 1094). Kev cai voltage piv - suav nrog 33/6.6kV thiab 35/0.4kV - yog muaj raws li qhov kev thov. Thov xa koj qhov project specification rau ib tug tailored configuration.
Q2: Puas yog qhov hloov pauv no puas txhawb nqa ntawm -load kais hloov pauv (OLTC), thiab dab tsi yog txoj cai?
Yog lawm. Chav tsev tau nruab nrog On -Load Tap Changer (OLTC) raws li tus qauv, npog ± 10% kev tswj hwm ntau ntawm 17 kais txoj haujlwm (± 8 × 1.25%). Ib qho Off-Circuit Tap Changer (OCTC) yog muaj los ua lwm txoj hauv kev rau cov ntawv thov uas cov khoom siv hluav taws xob ruaj khov.
