Kev piav qhia
1. Core txhais
Peb -theem transformer yog ib hom khoom siv hluav taws xob zoo li qub uas siv los hloov qhov voltage thiab tam sim no theem ntawm peb-theem alternating tam sim no. Nws lub luag haujlwm tseem ceeb zoo ib yam li ntawm ib qho -theem transformer, tab sis tshwj xeeb yog siv rau peb -theem fais fab, thiab feem ntau ntawm lub ntiaj teb tiam, kev sib kis, thiab kev faib tshuab yog peb -theem.
2.Main Structure
Ib qho peb-theem transformer feem ntau muaj ob ntu:
(1) Sib nqus Circuit Court (Core):
- Lub hauv paus ntawm peb-theem transformer feem ntau muaj peb ceg ceg, txhua qhov txhab nrog thawj (siab-}voltage) winding thiab theem nrab (tsawg-voltage) winding.
- Cov tub ntxhais kawm muab txoj hauv kev kaw rau peb -theem magnetic fluxes (Φ_A, Φ_B, Φ_C), uas yog 120 degrees tawm ntawm theem nrog ib leeg.
(2) Circuit Court (Windings):
- High-Voltage Winding: Lub kauj txuas nrog lub siab -voltage grid, feem ntau yog ua los ntawm finer insulated tooj liab lossis txhuas hlau.
- Tsawg-Voltage Winding: Lub kauj txuas nrog qis-voltage grid, feem ntau yog ua los ntawm cov hlau tuab nrog tsawg dua.
- Kev rwb thaiv tsev nruj yog siv nruab nrab ntawm cov windings thiab cov tub ntxhais, nrog rau nruab nrab ntawm qhov siab thiab qis voltage windings.
- Cov windings yog coj tawm los ntawm cov davhlau ya nyob twg txuas mus rau bushings ntawm transformer roj tank.
(3) Lwm Cov Cheebtsam: Cov no suav nrog cov roj tank, roj transformer (rau rwb thaiv tsev thiab cua txias), roj conservator (roj cushion), radiator, kev nyab xeeb ducts, roj relay (Buchholz relay), thiab lwm yam.
3. Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm peb -theem transformer yog raws li txoj cai ntawm electromagnetic induction, thiab nws yog qhov tseem ceeb zoo ib yam li ntawm ib qho -theem transformer.
- Voltage Transformation: Thaum peb -theem alternating tam sim no yog siv rau lub hauv paus winding, peb -theem alternating magnetic flux yog generated nyob rau hauv cov tub ntxhais.
- Induction: Qhov kev sib nqus sib nqus sib nqus no dhau los ntawm qhov sib nqus winding, ua rau lub zog hluav taws xob (voltage) nyob rau hauv qhov thib ob winding raws li Faraday txoj cai ntawm electromagnetic induction.
- Turns Ratio: Qhov ratio ntawm voltage nce los yog txo (transformer ratio) nyob ntawm qhov sib piv ntawm cov thawj thiab theem nrab windings. Yog tias thawj qhov kev hloov pauv (N1) ntau dua qhov thib ob hloov (N2), nws yog kauj ruam -down transformer (N1/N2 > 1); txwv tsis pub, nws yog ib kauj ruam - nce transformer.
3.Main Applications
- Fais fab nroj tsuag: Siv cov kauj ruam- nce transformers kom nce qhov voltage generated los ntawm generators (piv txwv li, 10.5kV) ntxiv rau -high voltage (piv txwv li, 110kV, 220kV, 500kV, los yog ntau dua) los txo cov kab poob thaum lub sij hawm ntev - kis tau tus mob.
- Transmission Networks: Ua qhov hloov pauv hluav taws xob ntawm cov kab sib txuas ntawm qhov sib txawv ntawm qhov sib txawv.Distribution Systems: Siv cov kauj ruam-down transformers (piv txwv li, 10kV / 0.4kV, feem ntau hu ua "ncej-mounted transformers" lossis "box-hom substations") kom kawg txo cov kab xa hluav taws xob mus rau theem tsim nyog rau cov chaw ua haujlwm, tsev neeg, khw.
- Industrial Sector: Muab cov hluav taws xob tsim nyog rau cov motors loj (xws li dov mills thiab twj), hluav taws xob rauv, khoom siv kho kom zoo, thiab lwm yam.
