QZS Pib Inverter Transformer

Lub QZS pib inverter transformer yog ib tug tshwj xeeb transformer uas integrates lub zog ntawm voltage-txo mos pib thiab fais fab mov rau ib tug inverter system. Nws lub ntsiab tseem ceeb yog tias nws tsis tsuas yog muab qhov txo qis pib rau siab -voltage motors, tab sis nws qhov thib ob winding tshwj xeeb yog tsim los muab lub zog rau lub inverter sab ntawm VVVF (variable voltage kuj sib txawv zaus) tsav uas tsav lub cev muaj zog, los yog rau lwm yam loads yuav tsum tau ib tug tsawg tsawg -voltage inverted fais fab mov.
Hauv cov ntsiab lus yooj yim, nws cov haujlwm tseem ceeb yog: 'pib lub cev muaj zog' thiab 'siv lub zog rau lub inverter'.

Noj ib txwm siab -lub zog asynchronous / synchronous lub cev muaj zog tsav los ntawm lub siab -voltage inverter ua piv txwv:

1.Pib- theem:
Lub cev muaj zog yuav tsum tau nrawm nrawm los ntawm qhov chaw nres tsheb mus rau nws qhov ntsuas ceev. Direct tag nrho-voltage pib tam sim no loj dhau, ua rau muaj kev cuam tshuam rau ntawm daim phiaj hluav taws xob thiab cov tshuab tshuab.
Lub siab -voltage sab ntawm QZS transformer yog txuas nrog rau daim phiaj hluav taws xob (xws li 10kV), thiab nws cov zis loj winding muab qhov txo qis (piv txwv li, 3kV) ncaj qha lossis los ntawm kev txwv tam sim no rau lub cev muaj zog, ua tiav qhov txo qis -voltage, tam sim no- txwv pib muag.

2.Inverter mov theem (qhov tseem ceeb sib txawv):
Nyob rau tib lub sijhawm, ib lossis ntau dua ywj siab qis -voltage thib ob windings ntawm QZS transformer pib ua haujlwm.
Qhov tsawg -voltage AC tso zis los ntawm cov windings (xws li, 380V, 400V, 690V, thiab lwm yam) raug xa mus rau lub inverter "inverter unit" los yog ib tug cais inverter ntaus ntawv.

Vim li cas nws thiaj hu ua "inverter"?
Nyob rau hauv niaj hnub high - fais fab tsav, inverters feem ntau siv "AC-DC- AC" qauv. Lawv xav tau lub hwj chim ywj pheej, cais tawm ntawm qhov chaw tswj, kom tsav lub rooj vag tsav tsheb ntawm lub inverter- sab IGBTs/IPMs, tswj fais fab, thiab kuaj xyuas circuits. Cov khoom siv hluav taws xob no xav tau kev ntseeg siab thiab kev sib cais siab los tiv thaiv kev cuam tshuam los ntawm dv / dt siab nyob rau hauv lub ntsiab Circuit Court mus rau qhov system tswj.
Lub "inverter winding" ntawm QZS transformer yog tsim los rau lub hom phiaj no. Nws muab lub "huv", txhim khu kev qha pab txhawb zog, hluav taws xob cais los ntawm lub siab -voltage main circuit, mus rau inverter's control core, kom ntseeg tau tias lub inverter tuaj yeem ua haujlwm ruaj khov thaum lub sijhawm pib lub cev muaj zog- nce qib thiab txawm koom nrog kev tswj xyuas meej ntawm kev pib- nce txheej txheem.

3. Hloov thiab ua haujlwm:
Thaum lub cev muaj zog nrawm nrawm mus ze ze ntawm lub ntsiab zaus nrawm los ntawm QZS transformer, lub kaw lus ua haujlwm hloov pauv.
Tom qab hloov, lub cev muaj zog txuas ncaj qha mus rau tag nrho daim phiaj hluav taws xob ua haujlwm, thiab lub inverter yuav raug hla lossis hloov mus rau lwm hom.
QZS transformer tau ua tiav nws lub luag haujlwm thiab raug txiav tawm ntawm daim phiaj. Nws yog ib qho khoom siv rau kev ua haujlwm luv luv -.

Hom transformer no yog siv nyob rau hauv cov xwm txheej uas ob qho tib si pib kev ua tau zoo thiab kev tswj xyuas kev ua haujlwm muaj cov kev xav tau siab, tshwj xeeb tshaj yog rau cov khoom siv loj uas tom qab hloov mus rau kev hloov pauv zaus tsav los yog tsim los ntawm qhov pib nrog cov kev daws teeb meem siab heev:

1.Energy-txuag kev hloov kho siab ntawm- kiv cua thiab twj tso kua mis: Los ntawm khaws cov qub motors thiab cov khoom siv hloov, kev teeb tsa ntawm high-voltage inverters thiab QZS pib inverter transformers tuaj yeem ua tiav ib qho kev sib xyaw 'soft start and variable frequency speed control,' uas tsis yog tsuas yog txo cov kev siv hluav taws xob thaum lub sij hawm pib tab sis tseem ceeb heev.

2. Cov khoom siv uas yuav tsum tau muaj kev tswj xyuas qhov tseeb: xws li mine hoists, rolling mills loj, thiab chaw nres nkoj thawv cranes, uas yuav tsum tau muaj qhov tseeb torque thiab ceev tswj lub peev xwm los ntawm qhov pib.

3.Qhov chaw uas yuav tsum tau muaj hwj chim zoo heev: xws li semiconductor factories thiab cov chaw zov me nyuam cov ntaub ntawv, qhov chaw uas sib txawv zaus soft starters yuav tsum tau siv los txo cov kab sib chaws cuam tshuam rau rhiab loads.

1.Multiple Windings, Ntau -Function:

• High-Voltage Input Winding: Txuas rau daim phiaj fais fab.
• Kauj Ruam -Kub Pib Winding: Muab qhov txo qis hluav taws xob rau lub cev muaj zog.
• Inverter Power Supply Winding (ib los yog ntau dua): Kev ywj pheej, qis-voltage, qis- cuam tshuam, tshwj xeeb tsim los muab lub zog rau lub inverter tswj seem. Qhov no yog nws qhov tshwj xeeb.

2.High Electromagnetic Compatibility Requirements:Lub zog tso zis ntawm nws 'inverter fais fab mov winding' yuav tsum yog 'huv' thiab tiv taus kev cuam tshuam. Thaum lub sij hawm tsim, lub shielding, kev sib cais, thiab rwb thaiv tsev ntawm winding yuav tsum tau muab tag nrho txiav txim siab kom tiv taus siab - zaus harmonics thiab voltage spikes generated los ntawm lub ntsiab Circuit Court.
3.Short-Lub Sijhawm Ua Haujlwm:Zoo li txhua qhov pib transformers, nws yog tsim los rau luv luv - lub sijhawm ua haujlwm (piv txwv li, 60-120 vib nas this), nrog rau qhov zoo ntawm qhov loj thiab tus nqi tshaj qhov hloov pauv uas npaj rau kev ua haujlwm tas mus li.
4.Highly Integrated nrog lub Inverter:Nws qhov tsis muaj (voltage, muaj peev xwm, impedance) yuav tsum precisely phim lub inverter -sab fais fab kev xav tau ntawm cov txuam inverter, ua rau nws ib tug heev customized tsis yog - cov khoom txheem.

QZS pib inverter transformer yog ib yam khoom lag luam ntawm kev txhim kho niaj hnub siab - fais fab fais fab tsav tshuab. Nws sawv cev rau cov evolution los ntawm qhov yooj yim 'txo voltage pib thiab excitation' hom mus rau ntau complex 'smooth pib thiab meej hluav taws xob tswj' hom. Nws yog ib qho tseem ceeb hub ntaus ntawv txuas rau high-voltage power grid, high-power motors, thiab advanced zaus conversion control systems.
