KEEB THAWJ XEEB |Tsim thiab tsim khoom ntawm inverter tu fais fab mov

Vim tias lub inverter siv cov khoom siv hluav taws xob sib txawv, nws yog ib qho tsim nyog los muab cov qib sib txawv ntawm qhov hluav taws xob thaum tswj lub inverter.Txawm li cas los xij, qhov tiag tiag peb-theem 200v AC voltage lossis peb-theem 400v AC voltage tsis tas yuav tsum tau rau kev tswj hwm qib lossis txawm tias chip theem tu (tsis li ntawd, thaum commissioning nrog load).Qhov yuav tsum tau muaj yog 200v thiab 400v AC voltage thiab coj 300v thiab 500v DC voltage.Txawm hais tias muaj ntau hom kev kho DC fais fab mov hauv khw, lawv kim heev thiab kev tiv thaiv tsis zoo.Nyob rau hauv ntau xyoo ntawm kev txij nkawm ua hauj lwm, tus sau tau ua ib tug tshwj xeeb inverter nti theem txij nkawm fais fab mov nrog ob qho tib si AC thiab DC voltage outputs thiab ua tiav kev tiv thaiv functions.

Manufacturing method I ntawm inverter txij nkawm fais fab mov:

Daim Ntawv Pov Thawj:

1 AC contactor 220V 32A Qhov ntau: 2

2 Transformer 220V rau 380V 500W Ib theem Quantity: 1

3 Tus lej ntawm tus kheej xauv khawm (txoj hauj lwm SB SB1) 2

4 Rectifier choj qauv MDQ100A Quantity: 1

5 Charging resistor (txoj hauj lwm RL) 120W60R Quantity: 1

6 Electrolytic capacitor (txoj hauj lwm C1 C2 C3 C4) 400V680UF Quantity: 4

7. Voltage equalizing resistor (txoj hauj lwm RC1 RC2 RC3 RC4), resistor 2W180k, kom muaj nuj nqis 4

8 DC voltmeter, DC1000V pointer yam

9 Discharge resistor (txoj hauj lwm RB) 120W60R Quantity: 1

Cov duab kos:

Txoj Kev II rau kev ua inverter tu fais fab mov:

Qee lub khw muag khoom, txwv los ntawm tej yam kev mob, tsis muaj peb-theem tu fais fab mov, uas ua rau muaj kev tsis yooj yim rau kev saib xyuas inverters, tshwj xeeb tshaj yog AC thiab DC voltage regulators (soft starters) thiab lwm yam khoom siv hluav taws xob.

Tom qab ob peb qhov kev ntsuam xyuas thiab tsim nyog optimization ntawm cov qauv, peb-theem inverter fais fab mov tau tsim thiab cov zis waveform tau sim.Nyob zoo!Zoo nkauj waveform, heev ze rau lub hwj chim mov.

Raws li pom hauv daim duab:

Thaum lub zaus converter nrog 380V peb-theem fais fab mov tau sib sau ua ke, KT1 ncua kev them nqi hluav taws xob yuav tsum tau ntxiv, thiab nws cov kev txwv yuav zoo ib yam li cov khoom siv hluav taws xob sab hauv.Kev rho tawm transformer txais 1: 1 hloov pauv piv;Yog tias lub converter nrog 220V input fais fab mov raug siv, KT1 tam sim no txwv qhov txuas tuaj yeem raug tshem tawm, thiab 220: 380 kauj ruam-up transformer yog siv los ua qhov sib cais transformer.Yog xaiv R2 = R1, lub peev xwm tiv tauj ntawm KT1 yuav tsum siab dua 5A.Yog hais tias nws tsis txaus, ib tug relay yuav tsum tau ntxiv.

Raws li qhov yuav tsum tau ua, T1T2 tuaj yeem sib phim raws li qhov tso zis tam sim no ntawm qhov hloov pauv zaus.Kuv siv ob txhais tes inverter, cais transformer thiab reactor uas tsis ua haujlwm thiab yooj yim kom tau.

Yog tias tsim nyog, rectifier lim Circuit Court tuaj yeem ntxiv rau theem tom ntej kom tau txais 0 ~ 550V adjustable DC txij nkawm fais fab mov.Thaum cov zis waveform tsis zoo, sim kho cov cab kuj zaus ntawm lub converter kom hloov mus rau LC filtering lub sij hawm tas li, thiaj li yuav tau txais cov zis waveform zoo dua.
