Txhua yam hais txog peb-theem transformer

Peb-theem transformer siv rau voltage hloov dua siab tshiab. Tus ntaus ntawv yog siv nyob rau hauv tus muaj sector ntawm electrification thiab tsev neeg xav tau kev pab. Ntxiv mus, xws li yog indispensable nyob rau hauv ships, txij li thaum lawv lub hwj chim pab kiag li lawm yog nqa tawm ntawm ntau yam denominations.

Muab xam los ntawm lub peb-theem transformer ua raws li cov kev cov ntaub ntawv. Raws li cov ntaub ntawv tau qhov yuav tsum tau cov khoom yog xaiv. Tus ntaus ntawv yog siv tsis tsuas yog rau cov muaj kev siv, tab sis kuj rau khoom vaj khoom tsev nyob rau hauv zus tau tej cov hluav taws xob kev tswj circuits.

Peb-theem transformer yuav muab nws txo qis los yog tsa, lub converted coefficient qhov tseem ceeb ywj siab ntawm tus xov tooj ntawm lem ntawm ob coils. Tus ntaus ntawv yuav tsum tau koom ua ke los ntawm ib tug peb-theem analogs los yog nqa rau ib qho tseem ceeb, tus nqi ntawm cov magnetic flux ntawm txhua theem nyob rau hauv xws li ib tug ntaus ntawv yuav pes tsawg.

Kom muaj transformers series ntawm kev ntsuam xyuas nqa tawm nyob rau txoj kev teev tsis. Complex ntsuas rau koj lub checking cov yam ntxwv ntawm tus ntaus ntawv muaj xws li cov kuj ntsuam ntawm txhua winding los ntawm rwb thaiv tsev nrog hwm rau hauv av, los yog nyob nruab nrab ntawm theem. Tshwj xeeb ntaus ntawv voltage yog thov mus rau lub coils thiab soj ntsuam allergic kev rho tawm. Ntxiv mus, cov thawj winding yog energized thiab lub ntsuas muaj nqis nyob rau hauv lub qhov zis. Siv no, cov transformation coefficient yog xam.

Ntsuas tau yuav tsum yoog mus rau qhov tseem ceeb reflected nyob rau hauv lub nrog cov ntaub ntawv, txwv tsis pub peb-theem transformer no tso tseg. Nws yog ib qho tseem ceeb kom to taub tias lub sam xauv nees thiab cov khoom siv installation rau Switchgear 110 kV thiab saum toj no yuav tsis pub tsis muaj kev saib xyuas cov kws muaj txuj los ntawm lub Hoobkas, qhov twg lawm yog nqa tawm. Nyob rau hauv cov ntaub ntawv no, lub xeem yuav tsum tau nqa tawm raws li lub txais cov kev cai nyob rau hauv lub xub ntiag ntawm ib tug competent neeg.

Peb-theem transformer yog kev cob cog rua rau ib tug "Star" los yog rau ib tug "daim duab peb sab". Star kev twb kev txuas yog pom tau hais cov ntawm ntawm tag nrho cov theem pib. Tsav nyob rau hauv ib tug daim duab peb sab ntawm successive theem compound mus rau hauv lub nplhaib: qhov kawg ntawm lub thawj theem yog ua ke nrog rau lub caij pib ntawm lub thib ob kawg ntawm tus thib ob thib peb nrog pib thiab thaum xaus ntawm lub thawj peb nrog pib.

Yog hais tias peb-theem transformer kev cob cog rua raws li lub "Star", lub ntsiab yuav ua tau nrog gluhozazemlonnoy los yog cais nruab nrab (thiaj li hu ua node txuas xaus theem). Rau high-voltage Switchgear, ib tug tshwj xeeb hood, uas tso cai rau hauv av thiab razzemlyat nruab nrab. Txawm li cas los, nyob rau hauv lub Switchgear kev ruaj ntseg 0.4 kV siv grounding zero.

Rau kev tiv thaiv ntawm hwj chim kav siv voltage transformers, los ntawm kev uas lub hwj chim yog tshuaj. Lawv pab coj lub kev tiv thaiv ntawm lub ces kaum thiab qhov tseem ceeb thaum teem tau ib differential teb kiag li lawm. Nyob rau hauv feem ntau tus neeg mob, peb transformers yog siv rau txhua theem.

Lawv txhua tus muaj tsawg kawg yog ob cores: ib kev cob cog rua rau hauv qhib raws, tus lwm yam - ib lub hnub qub. Star ua hauj lwm pab los ntsuas cov voltage rau cov kab thiab qhib daim duab peb sab yog yuav tsum tau raws li ib tug tiv thaiv kev txhaum.

Niaj hnub no muaj voltage transformers nrog peb punch nyob rau hauv accounting. Nrog nws, koj yog txuas txee. Raws li ib tug dav dav txoj cai, peb cov tub ntxhais kuj yog kev cob cog rua nyob rau hauv ib lub hnub qub. Qhov no sib cais ntawm cov tswj circuits los ntawm cov metering Circuit Court pab kom tau ntau yog nyeem ntawv, raws li cov tub ntxhais ntawm cov neeg hauv chav kawm ntawv 'meter' saum toj no.
