Tshawb nrhiav cov ntsiab lus dav dav rau cov roj immersed transformers, muaj cov roj immersed fais fab transformers thiab roj submersed faib transformers. Tshawb nrhiav lawv cov tswv yim ua haujlwm, hom, qhov zoo, thiab nce kev ua haujlwm hauv cov phiaj xwm ntse thiab cov peev txheej txuas ntxiv mus.
1. Intro rau Roj Submersed Transformers
Nyob rau hauv lub elaborate internet ntawm peb niaj hnub daim phiaj hluav taws xob, transformers ua lub luag haujlwm tseem ceeb, ntsiag to tipping voltage nce thiab nqis kom ntseeg tau tias lub zog tuaj yeem xa mus tau zoo hla lub teb chaws thiab faib kev nyab xeeb rau peb lub tsev thiab kev lag luam. Ntawm cov sib txawv muaj, cov roj submersed transformer sawv ua pov thawj rau kev ntseeg siab thiab ruaj khov. Rau xyoo, cov neeg ua haujlwm no tau tsim cov caj qaum ntawm lub tshuab hluav taws xob thoob ntiaj teb.
Cov roj immersed transformer yog ib hom hluav taws xob hloov hluav taws xob uas siv cov roj insulating tshwj xeeb raws li ob qho tib si coolant thiab cov cuab yeej insulating.. Qhov kev teeb tsa no feem ntau yog siv rau cov cuab yeej siv rau kev siv hluav taws xob siab, ua nws ib tug keystone ntawm hluav taws xob moj khaum. Phau ntawv qhia no khawb tob rau hauv lub ntiaj teb ntawm cov roj immersed fais fab transformers thiab roj submersed tis transformers, tshawb nrhiav lawv cov cuab yeej siv niaj hnub no, daim ntawv thov, thiab lawv txoj haujlwm tsim kho hauv lub hnub nyoog ntawm digitalization thiab cov peev txheej txuas ntxiv mus.
1.1 Dab tsi yog Roj Submersed Transformer?
Ntawm nws lub hauv paus, cov roj submersed transformer muaj xws li ib tug sib nqus core thiab tooj liab los yog lub teeb yuag aluminium windings nyob rau hauv ib lub thawv ruaj ruaj uas muaj ntaub thaiv npog roj.. Lub luag haujlwm tseem ceeb ntawm cov roj yog ob npaug:
1. Rwb thaiv tsev: Cov roj muaj siab dielectric zog, zoo insulating cov high-voltage windings los ntawm lub transformer lub core thiab grounded cia tank. Qhov no tiv thaiv luv luv Circuit Court thiab hluav taws xob tawg.
2. Txias: Raws li lub transformer ua haujlwm, cov windings tsim cov cua kub tseem ceeb los ntawm I ² R poob. Cov roj xa tawm absorbs qhov sov so, convects nws mus rau lub transformer lub thawv phab ntsa, thiab dissipates nws txoj cai rau hauv cov huab cua puag ncig. Cov khoom siv loj dua feem ntau muaj cov tshuab hluav taws xob lossis cov fins txhawm rau ua kom thaj chaw kom muaj cua txias ntau dua.
Qhov no ob lub hom phiaj siv roj ua rau cov roj submersed transformer tsis tshua muaj txiaj ntsig thiab muaj zog, nrog lub peev xwm ntawm kev tswj cov tons siab thiab tuav tawm tsam luv luv overloads zoo dua li ntau ntau yam kev xaiv qhuav.

Thaum tag nrho cov units no yog roj immersed transformers, lawv ua haujlwm tshwj xeeb hauv lub zog hluav taws xob network. Kev nkag siab qhov sib txawv yog qhov tseem ceeb.
Roj submersed hwj chim transformer yog hnyav hnyav, nquag siv hauv kev sib txuas lus ntawm kev tsim cov chaw nres tsheb thiab cov chaw tseem ceeb. Lawv lub luag haujlwm tseem ceeb yog ua “nce qib” qhov hluav taws xob tsim tawm ntawm lub tshuab hluav taws xob nuclear mus rau qib siab heev (e.g., 138 kV ua, 230 kV ua, 500 kV a ub) rau kev sib kis mus ntev, thiab rau “nqis nqis” qhov voltage ntawm txais substations rau kev ncig ntxiv. Lawv yog cov cim los ntawm lawv cov qhab nia siab zog heev (feem ntau tshaj 100 MVA), complex tsev thiab kev tsim kho, thiab on-load kais hloov pauv rau txoj cai voltage.
Ib tug roj koom nrog faib transformer, ntawm qhov tod tes, nqa tawm qhov kawg nkaus hauv cov saw fais fab. Nws yuav siv lub cuab tam voltage los ntawm cov kab sib kis (e.g., 11 kV ua, 33 kV ua) thiab qhia nws rau qhov tsawg voltages (e.g., 400/230 V) siv los ntawm kev lag luam thiab cov neeg siv khoom hauv tsev. Koj feem ntau pom lawv ntawm cov ntawv siv hluav taws xob (ncej-mounted) los yog nyob rau hauv pem teb pads (ncoo-mounted). Lawv yog cov me me, muaj qhov ntsuas hluav taws xob qis dua (feem ntau ntau npaum li 2,500 kVA ua), thiab yog tsim los rau kev ua tau zoo ntawm qhov qis, ntau ntau tas li.
