ntsuas transformers yog siv rau hauv kev tiv thaiv relay thiab automation circuits los soj ntsuam qhov loj ntawm tam sim no thiab voltage. Qhov no yog qhov tsim nyog kom cov kev tiv thaiv relay tuaj yeem ua haujlwm tau raws sijhawm raws li qhov teeb tsa los ntawm cov kws tsim khoom thaum teeb tsa cov khoom siv hluav taws xob. Raws li txoj cai, tam sim no thiab voltage ntsuas transformers yog siv nyob rau hauv relay tiv thaiv thiab automation circuits. Xav txog txhua yam sib cais.
Voltage transformers yog siv los taw qhia kev tiv thaiv, qhov no yog ib hom kev txhawb nqa, txheeb ze rau cov theem hloov pauv cov ces kaum raug suav, thiab kev tiv thaiv lub ntiaj teb txhaum kuj tau teeb tsa siv windings txuas nrog raws li cov phiaj xwm qhib daim duab peb sab.
ntsuas qhov hluav taws xob hloov hluav taws xob tau tsim nrog ntau lub cores: ib qho txuas nrog raws li "lub hnub qub" tswv yim, qhov thib ob - raws li "qhib daim duab peb sab". Niaj hnub no, manufacturers tsim transformers nrog ib tug thib peb core, uas yog siv rau metering.
Peb ib-theem voltage transformers raug ntsia rau RU-35-110 kV. Sib cais automata yog mounted rau txhua pawg kev sib txuas. Rau RU-6-10 kV, peb-theem VT hauv ib lub tsev feem ntau yog siv.
ntsuas tam sim no transformers yog siv nyob rau hauv tag nrho cov switchgears thiab yog ntsia rau theem ntawm theem. Cov transformers no yog ua los ntawm ib lub tsheb npav monolithic, uas yog thawj. Secondary windings yog tsau nyob rau hauv lub tsheb npav, tej zaum yuav muaj ob peb ntawm lawv, thiab txhua winding (tom qab no hu ua lub core) yog tsim los rau ib tug tej yam raug cov chav kawm ntawv thiab ib tug tshwj xeeb hwj chim.
Cores tau tso tawm rau kev tiv thaiv, kev suav nyiaj thiab ntsuas hluav taws xob. Nws yog ib qho tseem ceeb uas tam sim no transformers yeej tsis muaj luv luv-circuited cores, txwv tsis pub lub winding yuav kub hnyiab tau thiab cov neeg ua hauj lwm nyob rau hauv kev txaus ntshai ntawm electrocuted.
Thaum lub sijhawm teeb tsa, ntsuas tam sim no transformers yuav tsum tau teeb tsa raws li qhov voltage input-output circuit (L1 - input, L2 - output). Kev taw qhia ntawm cov vectors tam sim no ntawm txhua theem nyob ntawm qhov no. Raws li lub ntsiab lus ntawm lub cev, nruab nrab ntawm cov vectors tam sim no, cov windings uas txuas nrog raws li "Star" tswvyim, yuav tsum muaj 120 degrees. Yog tias vim li cas cov vectors nyob txawv, nws yuav tsum tau hloov qhov kev sib txuas ntawm TT cores los ntawm kev sib pauv qhov pib thiab xaus.
tam sim no transformers yog siv los tiv thaiv luv luv Circuit Court thiab rau kev teeb tsa kev tiv thaiv sib txawv. Kev ntsuas tam sim no transformers yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no, qhov no yog hom sensor uas txiav txim siab qhov loj ntawm qhov tam sim no thiab nws cov kev taw qhia.
Hauv kev teeb tsa hluav taws xob, siv xoom-ib theem hloov pauv. Cov khoom no muaj feem xyuam rau RU-0, 4-6-10 kV,txij li txoj haujlwm ntawm lub tshuab hloov pauv (nyob rau hauv lub neej niaj hnub ib qho khoom noj) yog los tiv thaiv cov hluav taws xob hluav taws xob hluav taws xob los ntawm kev ua txhaum hauv av. Nws lub ntsiab yog feeder nws tus kheej, uas yog dhau los ntawm ib tug bagel. Tus nqi yog coj los ntawm qhov thib ob, uas hloov pauv raws li qhov kev hloov pauv hauv qhov chaw sib nqus ntawm lub feeder.
Yog li, transformers rau ntsuas tam sim no thiab voltage yog lub hauv paus ntawm kev tiv thaiv. Ua tsaug rau lawv, niaj hnub microprocessors tuaj yeem suav tus kheej ntawm lub zog, qhov kev tiv thaiv ntawm ntu Circuit Court, cov ces kaum ntawm tam sim no thiab voltage. Cov txiaj ntsig tau txais tsis xav tau kev pov thawj, vim tias cov cuab yeej siv niaj hnub no tau tsim los siv cov thev naus laus zis tshiab.
Hnub no, cov khoom siv uas yog cov kev daws teeb meem nyuaj thiab suav nrog lub tshuab hluav taws xob, lub tshuab hluav taws xob, nrog rau cov khoom siv hauv CTs thiab VTs tau nrov heev niaj hnub no - qhov no yooj yim thiab muaj txiaj ntsig zoo.
