Voltage transformer - ib tug indispensable ntsuas

Tuam txhab uas muag uas koom nyob rau hauv lub purchase, muag hluav taws xob, feem ntau kom cov ntaub ntawv ntawm kev noj ntawm cov kev pab, poob nqi, raws li zoo raws li pab tau chaw. Rau xws li ua hauj lwm yog feeb siv tam sim no thiab voltage transformers. Xws li muaj peev xwm mus ua hauj lwm nyob rau hauv tes hauj lwm ntawm high voltage tsis muaj ntxiv kiag li lawm. Tej khoom no yog npaj rau rwb thaiv tsev ntawm theem nrab circuits thiab cov kev cob cog rua xab cov khoom siv los ntawm high-voltage khoom. Me qhov tseem ceeb ntawm voltage thiab tam sim no pub rau ua xws li ntau compact thiab yooj yim.

Tam sim no transformers (CTS) yog siv los hloov loj ntxhee nyob rau hauv me me qhov ntau. Lawv yog tsim rau xab ib ntau yam ntawm cov kev seev. Nyob rau hauv tas li ntawd, nws tso cai rau koj los tiv thaiv cov xab Circuit Court los ntawm cov tej yam tsis zoo ntawm luv luv-Circuit Court.

tom ntej no TT distinguished los ntawm tsim:

1. Siv.

2. Tire.

3. Ua.

4. Dua.

5. Split.

6. Hluav taws xob cov ciaj.

Tus tam sim no transformer yog raws li nram no:

1. Cov ntau zaus haum rau kev ua hauj lwm.

2. Cov coefficient ntawm transformation.

3. Raug.

4. Raug.

5. Nyob tam sim no.

6. Qhov siab tshaj plaws tam sim no.

Nyob rau hauv lem, tus voltage transformer (VT) yog siv los txo cov magnitude rau qhov tseem ceeb yooj yim rau kev ntsuas. Los ntawm lub electromagnetic coupling ntawm cov thawj thiab theem nrab windings ntawm cov kev rho tawm cov khoom yog ntsuas circuits, thiab qhov kev sib cais ntawm cov kev tiv thaiv relay khoom ntawm high-voltage network. Yuav ua kom muaj kev ruaj ntseg ntawm electrotechnical neeg khiav hauj lwm cov pab kiag li lawm, yog ib lub terminals ntawm ob winding yog grounded. Lub qhov txawv feature, uas muaj ib tug voltage transformer, - nws tej hom kev zov me nyuam nyob ze rau idling. Nyob rau hauv cov ntaub ntawv no, tus kuj muaj nqis yog txaus loj, thiab tam sim no tus nqi, nyob rau hauv tsis tooj, yog me me. Li ntawd, cov transformer luv luv-Circuit Court voltage yog Attendance raug ntaus.

Txhua VT nws muaj nws tus yam ntxwv, uas yog qhia nyob rau hauv cov nqe lus ntawm:

1. Raug, uas yog nyob rau hauv lub nqus permeability thiab sib nqus qauv. Txo active tivthaiv tej zaum yuav txo tus naj npawb ntawm lem nyob rau hauv cov thawj winding, thiab ua ntawv thov cov compensating ntaus ntawv.

2. Raug kev ntsuam xyuas.

3. Cov coefficient ntawm transformation.

4. Qhov siab tshaj plaws voltage.

5. Nyob voltage.

Los ntawm lawv tsim kho theem thiab peb theem VT. Thawj siv rau tej voltage, lub thib ob - rau voltage mus txog 18,000 V.
Raws li siv rwb thaiv tsev cais qhuav, oily thiab cam khwb cia.
Tsis zoo li tam sim no transformer uas yog muaj nyob rau hauv ib tug network nyob rau hauv series, ib tug voltage ntsuas transformer thawj winding yog kev cob cog rua thaum uas tig mus rau lub xab Circuit Court.

Kev txiav txim tsis ntsuas Circuit Court yog raws li nram no: ib tug nqi uas qhia tau hais tias ib tug voltage transformer thiab tam sim no, multiplied by lub duas paub transformation coefficient ntaus ntawv.

Lub peculiarity ntawm ntsuas transformers yog tias tau ib qho qhib theem nrab winding nruj me ntsis tshem tawm kev nyab xeeb kev tswj cai.
