PHUNZIRO |Kupanga ndi kupanga magetsi opangira inverter

Chifukwa inverter imagwiritsa ntchito ma voltages osiyanasiyana, ndikofunikira kupereka magawo osiyanasiyana amagetsi pakusunga inverter.Komabe, voteji yeniyeni ya magawo atatu a 200v AC kapena voteji ya 400v AC ya magawo atatu safunikira kwenikweni pakukonza mulingo wa bolodi kapena kukonza chip level (apo ayi, mukatumiza katundu).Chofunikira ndi 200v ndi 400v AC voteji ndi 300v ndi 500v DC voteji.Ngakhale pali mitundu yambiri yamagetsi osinthika a DC pamsika, ndi okwera mtengo ndipo ntchito yoteteza si yabwino.M'zaka zambiri za ntchito yokonza, wolembayo wapanga magetsi apadera a inverter chip level ndi zotulutsa zonse za AC ndi DC komanso ntchito zonse zoteteza.

Kupanga njira I ya magetsi opangira inverter:

Bili ya Zida:

1 AC contactor 220V 32A Kuchuluka: 2

2 Transformer 220V mpaka 380V 500W Single gawo Kuchuluka: 1

3 Nambala ya mabatani odzitsekera (malo SB SB1) 2

4 Rectifier Bridge Model MDQ100A Kuchuluka: 1

5 Kutsatsa kotsutsa (malo RL) 120W60R Kuchuluka: 1

6 Electrolytic capacitor (malo C1 C2 C3 C4) 400V680UF Kuchuluka: 4

7. Voltage equalizing resistor (malo RC1 RC2 RC3 RC4), resistor 2W180k, kuchuluka 4

8 DC voltmeter, DC1000V mtundu wa pointer

9 Discharge resistor (malo RB) 120W60R Kuchuluka: 1

Njira II yopangira magetsi opangira ma inverter:

Mashopu ena okonza, ocheperako, alibe magetsi opangira magawo atatu, zomwe zimabweretsa zovuta pakukonza ma inverters, makamaka ma AC ndi DC voltage regulators (zoyambira zofewa) ndi zida zina zamagetsi.

Pambuyo pa mayeso angapo komanso kukhathamiritsa koyenera kwa kapangidwe kake, magetsi a inverter magawo atatu adapangidwa ndipo mawonekedwe otuluka adayesedwa.Moni!Mawonekedwe okongola, pafupi kwambiri ndi magetsi.

Monga momwe chithunzichi chikuwonekera:

Pamene chosinthira pafupipafupi chokhala ndi 380V chamagetsi cha magawo atatu chasonkhanitsidwa, gawo lozengereza la KT1 lidzawonjezedwa, ndipo magawo ake amatha kukhala ofanana ndi omwe amazungulira mkati.The kudzipatula thiransifoma utenga 1: 1 kusintha chiŵerengero;Ngati chosinthira chokhala ndi magetsi a 220V chikugwiritsidwa ntchito, ulalo wapakalipano wa KT1 ukhoza kusiyidwa, ndipo chosinthira cha 220:380 chokwera chimagwiritsidwa ntchito ngati chosinthira chodzipatula.Ngati R2=R1 yasankhidwa, mphamvu yolumikizana ndi KT1 iyenera kukhala yayikulu kuposa 5A.Ngati sichikukwanira, relay iyenera kuwonjezeredwa.

Monga momwe zimafunikira, T1T2 imatha kufananizidwa molingana ndi momwe ma frequency asinthira.Ndimagwiritsa ntchito inverter yachiwiri, thiransifoma yodzipatula ndi riyakitala yomwe ili yopanda pake komanso yosavuta kupeza.

Ngati ndi kotheka, gawo losinthira zosefera litha kuwonjezeredwa pambuyo pake kuti mupeze magetsi osinthika a 0 ~ 550V DC.Pamene mawonekedwe a waveform sali abwino, yesani kusintha ma frequency otengera chosinthira kuti agwirizane ndi kusefa kwa LC nthawi zonse, kuti mupeze zotsatira zabwino za ma waveform.
