Mfundo zazikuluzikulu zogulira ma alternators abwino a AC ndi ati

Pakali pano, kusowa kwa magetsi padziko lonse kukukulirakulira.Makampani ambiri ndi anthu amasankha kugula ma jenereta kuti achepetse zoletsa pakupanga ndi moyo chifukwa cha kusowa kwa mphamvu.AC alternator ndi imodzi mwamagawo ofunikira pamajenereta onse.Momwe mungasankhire ma alternators odalirika, malangizo otsatirawa ayenera kuzindikirika:

I. Makhalidwe amagetsi:

1. Dongosolo lachisangalalo: Panthawiyi, makina osangalatsa amtundu wapamwamba wa AC alternator amadzisangalatsa okha, omwe nthawi zambiri amakhala ndi automatic voltage regulator (AVR).Mphamvu yotulutsa ya exciter rotor imatumizidwa ku rotor yolandila kudzera pa rectifier.Kusintha kwamagetsi kwa AVR nthawi zambiri kumakhala ≤1%.Pakati pawo, AVR yapamwamba imakhalanso ndi ntchito zingapo monga ntchito yofananira, chitetezo chochepa pafupipafupi, komanso kusintha kwamagetsi akunja.

2. Kusungunula ndi varnish: Gulu lotsekemera la alternators apamwamba nthawi zambiri limakhala la "H", ndipo mbali zake zonse zokhotakhota zimapangidwa ndi zipangizo zopangidwa mwapadera ndipo zimayikidwa ndi njira yapadera.Alternator imayenda m'malo ovuta kuti apereke chitetezo.

3. Kuthamanga ndi mphamvu zamagetsi: Stator ya alternator yapamwamba idzapangidwa ndi zitsulo zozizira zozizira zomwe zimakhala ndi maginito amphamvu, maginito awiri, mawonekedwe amphamvu ndi ntchito yabwino yotsekemera.

4. Kusokoneza foni: THF (monga tafotokozera BS EN 600 34-1) ndi yochepa kuposa 2%.TIF (monga tafotokozera NEMA MG1-22) ndi yocheperapo 50

5. Kusokoneza wailesi: Zida zapamwamba zopanda brushless ndi AVR zidzaonetsetsa kuti pasakhale zosokoneza panthawi yotumizira wailesi.Ngati ndi kotheka, chipangizo chowonjezera cha RFI chikhoza kuikidwa.

II.Makhalidwe amakanika:

Mlingo wachitetezo: Mitundu yokhazikika ya majenereta onse a AC ndi IP21, IP22 ndi IP23 (NEMA1).Ngati pali chofunikira chachitetezo chapamwamba, mutha kusankha kukweza mulingo wachitetezo cha IP23.Mtundu wokhazikika wa jenereta ya AC yam'madzi ndi IP23, IP44, IP54.Ngati mukufuna kukonza mulingo wachitetezo, monga chilengedwe ndi nyanja, mutha kupatsa jenereta ya AC ndi zida zina, monga zotenthetsera mlengalenga, zosefera mpweya, ndi zina zambiri.

Kuperewera kwa mphamvu padziko lonse lapansi kwachulukitsa kwambiri kugulitsa kwa ma AC alternator/jenereta.Mitengo ya zida za ma generator a AC monga ma disc couplings ndi ma rotor akwera kudutsa gulu lonse.Kupereka ndi kolimba.Ngati mukufuna magetsi, mutha kugula ma generator a AC posachedwa.Mtengo wamajenereta a AC nawonso ukukwera mosalekeza!
