Kumvetsetsa wamba kwa ng’anjo yotenthetsera induction
Kuganiza bwino kwa magetsi oyatsira moto
1. Mphamvu yamagetsi ya ng’anjo yotenthetsera yotenthetsera ndi magawo atatu osinthasintha, mafupipafupi ndi 50Hz, ndipo magetsi olowera ndi 380V. Kwa ng’anjo zotenthetsera zamphamvu kwambiri, magetsi olowera amathanso kukhala 660V, 750V, 950V, ndi zina zambiri.
2. Kutentha kwa ng’anjo yotentha kumayendetsedwa ndi transformer, yomwe ingagawidwe m’mitundu iwiri: owuma owuma ndi opangira mafuta opangira mafuta molingana ndi zofalitsa zosiyanasiyana zozizira. Mu magetsi oyatsira moto makampani, timalimbikitsa mafuta-utakhazikika rectifier thiransifoma.
3. Pansi pa voliyumu yovomerezeka kapena katundu woyengedwa, mphamvu yotulutsa ng’anjo yotenthetsera induction ikhoza kusinthidwa bwino komanso mosalekeza, ndipo kusintha kosinthika ndi 5% -100% ya mphamvu yovomerezeka;
4. Kabati yosinthira mphamvu yamagetsi ya ng’anjo yotenthetsera induction ndiye gawo lalikulu, lomwe limapangidwa ndi magawo awiri: rectifier / inverter. Ntchito ya gawo la rectifier ndi njira yosinthira 50HZ alternating current kukhala pulsating direct current. Malinga ndi kuchuluka kwa pulse rectification, imatha kugawidwa mu 6-pulse rectification, 12-pulse rectification, ndi 24-pulse rectification. Pambuyo pokonzanso, chowongolera chowongolera chidzalumikizidwa mndandanda ndi mzati wabwino. Ntchito ya gawo la inverter ndikusintha mafunde achindunji omwe amapangidwa ndi kukonzanso kukhala ma frequency apakatikati omwe amasinthasintha ndikupereka mphamvu ku coil induction.
5. Pamene voteji yotulutsa ng’anjo yotenthetsera induction ipitilira nthawi 1.1-1.2 ya voteji yayikulu kwambiri kapena ipitilira mtengo wamagetsi, chitetezo chamagetsi chowonjezera chidzachitapo kanthu kuti chipangizocho chizisiya kugwira ntchito ndikutulutsa chizindikiro cha alamu – yatsani overvoltage chizindikiro kuwala kwa bokosi chida.
6. Kabati ya capacitor ya ng’anjo yotenthetsera induction ndi chipangizo chomwe chimapereka chipukuta misozi champhamvu ku coil induction. Zitha kumveka bwino kuti kuchuluka kwa capacitance kumakhudza mwachindunji mphamvu ya zida. The parallel resonance induction induction ng’anjo imakhala ndi mtundu umodzi wokha wa resonance capacitor (electric heat capacitor), pomwe ng’anjo yowotchera yotsatsira ili ndi ma capacitor osefera kuwonjezera pa resonance capacitor (electric heat capacitor).
7. Pamene mlatho wa inverter wa ng’anjo yotentha yotentha umagwirizanitsidwa mwachindunji ndi kufupikitsidwa, chitetezo chidzachitapo kanthu mwamsanga kuti chiyimitse chipangizocho, ndikutumiza chizindikiro cha overcurrent – kuyatsa chizindikiro cha overcurrent cha bokosi la chida.
8. Pamene mphamvu yogwira ntchito ya makina oziziritsa madzi a ng’anjo yotenthetsera yolowera ndi yotsika kuposa mtengo wina, zida zotenthetsera zotenthetsera, kuzimitsa zida zochizira kutentha, ndikuzimitsa ndi kutenthetsa mzere wopanga kutentha zimatha kuyimitsa ndikuyatsa kuthamanga kwamadzi. chizindikiro pa gulu.
9. The pafupipafupi kutembenuka chipangizo cha magetsi oyatsira moto imatengera thyristor SCR, yomwe ndi gawo lalikulu la gawo lamagetsi. Ntchito ya thyristor yosankhidwa idzakhudza mwachindunji ntchito ya zipangizo. Magulu omwe amagwiritsidwa ntchito kwambiri ndi thyristor,
1) KP mtundu wamba thyristor, kawirikawiri ntchito rectification;
2) KK mtundu wachangu thyristor, zambiri ntchito inverter;
- KF mtundu asymmetric thyristor ndi mtundu watsopano wa thyristor wopangidwa m’zaka zaposachedwa, womwe umagwiritsidwa ntchito mu zida za inverter.
