1. Qhia txog Roj-Immersed Transformers
Hauv lub network nthuav dav ntawm peb daim phiaj hluav taws xob niaj hnub no, transformers ua lub luag haujlwm tseem ceeb, ntsiag to nce thiab nqis kom ntseeg tau tias lub zog tuaj yeem xa tau zoo thoob plaws lub tebchaws thiab faib nyab xeeb rau peb lub tsev thiab kev lag luam. Ntawm cov ntau hom muaj, cov roj-raus transformer sawv raws li ib tug ua tim khawv rau pov thawj kev ntseeg tau thiab kav ntev. Rau xyoo, cov workhorses tau tsim tus txha caj qaum ntawm lub hwj chim systems thoob ntiaj teb.
Ib tug roj-raus transformer yog ib hom ntawm hluav taws xob transformer uas siv ib tug tshwj xeeb rwb thaiv tsev roj raws li ob qho tib si ib tug coolant thiab ib tug insulating nruab nrab. Qhov kev teeb tsa no tsuas yog siv rau cov ntawv thov nruab nrab mus rau lub zog siab, ua rau nws yog qhov tseem ceeb ntawm kev tsim hluav taws xob. Phau ntawv qhia no delves tob rau hauv lub ntiaj teb ntawm roj-raus fais fab transformers thiab roj-submersed faib transformers, tshawb nrhiav lawv cov thev naus laus zis, daim ntawv thov, thiab lawv lub luag haujlwm hloov zuj zus hauv ib lub caij nyoog ntawm digitalization thiab kev siv hluav taws xob txuas ntxiv.
1.1 Dab tsi yog Roj-Submersed Transformer?
Ntawm nws cov tub ntxhais, Ib qho roj-submersed transformer yog tsim los ntawm cov tub ntxhais sib nqus thiab tooj liab lossis txhuas windings nyob sab hauv a kaw lub thawv ntim nrog rwb thaiv tsev. Lub luag haujlwm tseem ceeb ntawm cov roj yog ob npaug:
1. Rwb thaiv tsev: Cov roj muaj lub zog siab dielectric, zoo rwb thaiv tsev cov hluav taws xob siab los ntawm lub transformer cov tub ntxhais thiab lub tank hauv av. Qhov no tiv thaiv luv luv circuit Court thiab hluav taws xob tawg.
2. Txias: As the transformer operates, the windings produce significant heat as a result of I ² R losses. The distributing oil absorbs this warmth, convects it to the transformer’s container wall surfaces, and dissipates it right into the surrounding air. Bigger devices usually feature radiators or fins to increase the area for much more efficient cooling.
This dual-purpose use oil makes the oil submersed transformer extremely efficient and robust, with the ability of managing high tons and holding up against short-term overloads much better than lots of dry-type choices.
1.2 Oil Immersed Power Transformer vs. Oil Immersed Distribution Transformer
While all these units are oil immersed transformers, they serve distinctive features within the power system network. Comprehending the distinction is crucial.
An oil submersed power transformer is a heavyweight, normally used in transmission networks at creating stations and significant substations. Their key function is to “step-up” the voltage produced at the nuclear power plant to very high levels (piv txwv li,, 138 kV, 230 kV, 500 kV and above) for effective long-distance transmission, and to “step-down” the voltage at receiving substations for further circulation. They are characterized by their very high power scores (commonly surpassing 100 MVA), complex building and construction, and on-load tap changers for voltage policy.
An oil involved distribution transformer, ntawm qhov tod tes, carries out the last action in the power delivery chain. It takes the tool voltage from the transmission lines (piv txwv li,, 11 kV, 33 kV) and tips it to the low voltages (piv txwv li,, 400/230 V) used by business and household consumers. You typically find them on utility posts (pole-mounted) or on ground-level pads (ncoo-mounted). Lawv yog me me, muaj qis zog ntsuas (feem ntau ntau npaum li cas 2,500 kVA), thiab yog tsim rau qhov zoo tshaj plaws ntawm qis dua, ntau ntau tas li loads.
