Qhov sib txawv ntawm ib-theem inverter thiab peb-theem inverter

1. Ib-theem inverter

Ib theem inverter converts DC input rau hauv ib-theem tso zis.Cov zis voltage / tam sim no ntawm ib theem inverter tsuas yog ib theem xwb, thiab nws cov nominal zaus yog 50HZ lossis 60Hz nominal voltage.Lub nominal voltage yog txhais raws li qhov voltage theem ntawm lub tshuab hluav taws xob ua haujlwm.Muaj qhov sib txawv nominal voltages, piv txwv li 120V, 220V, 440V, 690V, 3.3KV, 6.6KV, 11kV, 33kV, 66kV, 132kV, 220kV, 400kV, thiab 765kV vim li cas ntau lub zog xa mus rau 1 (Rel) , Qhov ntawd yog 11kV, 22kV, 66kV, thiab lwm yam?

Tsawg nominal voltages tuaj yeem ua tiav ncaj qha los ntawm inverter siv lub tshuab hluav taws xob sab hauv lossis cov kauj ruam-up booster Circuit Court, thaum lub siab nominal voltages siv lub zog hluav taws xob sab nraud.

Ib-theem inverter yog siv rau kev thauj khoom tsawg.Piv nrog rau peb-theem inverter, qhov poob ib zaug yog loj dua thiab qhov ua tau zoo yog qis dua.Yog li ntawd, peb-theem inverters yog nyiam rau kev thauj khoom siab.

2. Peb-theem inverter

Peb-theem inverters hloov DC mus rau peb-theem fais fab.Peb-theem fais fab mov muab peb alternating tam sim no nrog cov sib npaug sib cais theem kaum.Tag nrho peb lub nthwv dej uas tsim tawm ntawm qhov kawg tso tawm muaj qhov sib npaug thiab qhov zaus, tab sis txawv me ntsis vim kev thauj khoom, thaum txhua nthwv dej muaj 120o theem hloov ntawm ib leeg.

Yeej, ib zaug peb-theem inverter yog 3-theem ib-theem inverters, qhov twg txhua lub inverter yog 120 degrees tawm ntawm theem, thiab txhua ib-theem inverter txuas nrog ib qho ntawm peb lub load terminals.

Cov ntsiab lus Xauj: Dab tsi yog peb-theem inverter, lub luag haujlwm yog dab tsi

Muaj qhov sib txawv topologies rau kev tsim peb-theem voltage inverter circuits.Yog tias nws yog tus choj inverter, khiav qhov hloov mus rau hauv 120 degree hom kev ua haujlwm ntawm peb-theem inverter ua rau txhua qhov hloov pauv mus rau tag nrho lub sijhawm ntawm T / 6, uas ua rau cov zis tawm nrog 6 kauj ruam.Muaj ib qho xoom voltage theem ntawm qhov zoo thiab qhov tsis zoo voltage theem ntawm square nthwv dej.

Qhov ntsuas hluav taws xob inverter tuaj yeem nce ntxiv.Txhawm rau tsim lub inverter nrog lub zog siab, 2 inverters (peb-theem inverters) tau txuas nrog hauv series kom tau txais qhov ntsuas hluav taws xob siab.Rau cov kev ntsuas siab tam sim no, 2 6-kauj ruam 3 inverters tuaj yeem txuas nrog.
