Kusiyana pakati pa single-phase inverter ndi atatu-phase inverter

1. Inverter ya gawo limodzi

Inverter ya gawo limodzi imasintha cholowetsa cha DC kukhala gawo limodzi.Mphamvu yamagetsi / yapano ya inverter ya gawo limodzi ndi gawo limodzi lokha, ndipo ma frequency ake odziwika ndi 50HZ kapena 60Hz mwadzina voteji.Mphamvu yamagetsi yadzina imatanthauzidwa ngati mlingo wa voteji momwe magetsi amagwirira ntchito.Pali ma voltages osiyanasiyana, mwachitsanzo, 120V, 220V, 440V, 690V, 3.3KV, 6.6KV, 11kV, 33kV, 66kV, 132kV, 220kV, 400kV, ndi 765kV manambala amagetsi pa1 izi: , Ndi 11kV, 22kV, 66kV, etc.?

Ma voltages otsika amatha kupezedwa mwachindunji kudzera pa inverter pogwiritsa ntchito chosinthira chamkati kapena chowongolera chowongolera, pomwe ma voltages apamwamba kwambiri chosinthira chakunja chimagwiritsidwa ntchito.

Ma inverter a gawo limodzi amagwiritsidwa ntchito pa katundu wochepa.Poyerekeza ndi inverter ya magawo atatu, kutayika kwa gawo limodzi kumakhala kokulirapo komanso kuchita bwino kumakhala kotsika.Chifukwa chake, ma inverters agawo atatu amakondedwa pazolemetsa zambiri.

2. Magawo atatu inverter

Ma inverter amagawo atatu amasintha DC kukhala mphamvu yamagawo atatu.Mphamvu yamagetsi yamagawo atatu imapereka ma alternating apano atatu okhala ndi ngodya zogawanika.Mafunde onse atatu opangidwa pamapeto otuluka amakhala ndi matalikidwe ofanana ndi mafupipafupi, koma amasiyana pang'ono chifukwa cha katundu, pamene mafunde aliwonse ali ndi kusintha kwa gawo la 120o pakati pawo.

Kwenikweni, inverter imodzi yamagawo atatu ndi ma inverter a 3 gawo limodzi, pomwe inverter iliyonse imakhala ndi madigiri 120 kuchokera pagawo, ndipo inverter iliyonse yagawo limodzi imalumikizidwa ndi imodzi mwazotengera zitatu.

Sakatulani zamkati: Kodi inverter ya magawo atatu ndi chiyani, ntchito yake ndi yotani

Pali ma topology osiyanasiyana omangira magawo atatu ma voltage inverter.Ngati ndi inverter mlatho, kuthamanga lophimba mu mode 120 digiri ntchito ya magawo atatu inverter kumapangitsa lophimba aliyense ntchito kwa nthawi okwana T/6, umene umabala linanena bungwe waveform ndi 6 masitepe.Pali sitepe ya zero voltage pakati pa ma voliyumu abwino ndi oyipa a square wave.

Mphamvu ya inverter imatha kuwonjezeredwa.Kuti apange inverter yokhala ndi mphamvu yayikulu, 2 inverters (ma inverters atatu) amalumikizidwa mndandanda kuti apeze voteji yapamwamba.Pazowerengera zamakono, ma inverters a 2 6-step 3 akhoza kulumikizidwa.
