Thyristor mphamvu yang'anira: mfundo kanthu ndi ukulu

Pa nthawi ya mapangidwe chuma kunali muyenera zipangizo zapadera. Cholinga chachikulu anali kulenga njira osakhala mgwirizano wa kusintha ndi kukhazikitsa awo zopindulitsa, ulimi alipo. Izi zinayamba kutheka mkubwela kwa zipangizo michenga yopangira zida zamagetsi mphamvu zamagetsi ziwembu. Thyristor mphamvu yang'anira wakhala chimagwiritsidwa ntchito onse m'madera onse kupanga ndi tsiku ndi tsiku. Ndi zinabala kulamulira yosalala ya mowa magetsi mu zipangizo banja makhazikitsidwe mphamvu. ukulu ndi lingamutsatire - onse zipangizo kudziwika mphamvu yopulumutsa, mwachitsanzo, chifukwa soldering mpaka kulamulira kutentha ng'anjo kupatsidwa ulemu.

Choncho, thyristor mphamvu yang'anira athandiza pamene ntchito ndi katundu yogwira-inductive. ntchito zake ng'anjo magetsi kapena zipangizo ndi kwambiri zothandiza. Wolapadi mowa mphamvu ndipo ali Mwachangu mkulu. Pafupifupi 99 peresenti ntchito kukhazikitsa ogula. M'pofunikanso kukumbukira komanso kudalilika mkulu ntchito. Kutentha lamulo Sikuti kuonjezera dongosolo kulamulira liwiro. Sinkhasinkha pa / kutali zigawo mphamvu n'kopindulitsa nchito zawo kwambiri chimafikira kutalika kwa moyo wawo. Chotero thyristor mphamvu yang'anira ali makhalidwe opaleshoni wabwino.

Komanso chidwi ndi khalidwe la katunduyo. Kutentha zipangizo amakonda kukhala otsika inductance. Chonchi dera thyristor mphamvu yang'anira kosamugonjera zinthu chowawa. Iwo amakumana pamene akugwira inductance lapansi. N'zosiyana uyenderere ali pafupifupi inathetsedwa, zomwe zimatithandiza kapangidwe chipangizo palokha, ndipo kumakhudzanso moyo wa gawo mphamvu.

Good kuchira katundu zipangizo michenga yopangira zida zamagetsi mokwanira chinkhoswe ntchito zipangizo zimenezi. Pa zimamuchulukira mwachidule akutsatiridwa ndi kuchotsa awo, thyristor akuchira ndi lidakali monga kale. Koma kuchulukana mu madera amenewa - izi ndi zosiyana. Mu mode wabwinobwino, mphamvu thyristor owongolera ntchito ndi bwino osankhidwa MF. Childs, pano pafupifupi, kupereka katundu panopa zosakwana oveteredwa zigawo mphamvu.

Pamene dongosolo kulamulira kawirikawiri amagwiritsidwa ntchito ziwembu nzeru. Kugwiritsa PWM Mtsogoleri adzakhala tichotse accelerations mkulu pa zipangizo kuyamba mphamvu. kusintha mphamvu si anakhudzidwa ndi kuipa kwa kopitilira muyeso-lalikulu mafunde inrush. Izi kumakhudzanso moyo wa transducers ndi akulola servo mode kulamulira magawo zonse zofunikira.

Ngakhale zikamera wa zinthu zatsopano Mwachitsanzo, IGBT-zigawo, opha thyristor mphamvu kusungira malo amphamvu m'madera onse. Kwa chiwerengero cha ntchito yawo, iwo ali patsogolo zipangizo zambiri nzeru.
