Kodi mungasankhire bwanji ng’anjo yapamwamba yosungunuka?

1. Dera lowongolera la ng’anjo yosungunula induction ndi rectifier ya mlatho, yomwe imagawidwa m’magawo atatu ndi magawo asanu ndi limodzi. Pakati pawo, gawo lachitatu la bridge rectifier limapangidwa ndi magulu atatu a thyristors, omwe amadziwika kuti six-pulse rectification; gawo lachisanu ndi chimodzi la bridge rectifier limapangidwa ndi magulu asanu ndi limodzi a thyristors, omwe amadziwika kuti twelve-pulse rectification; amagwiritsidwanso ntchito m’ng’anjo zosungunula zamphamvu kwambiri. Pali makumi awiri ndi anayi kugunda kwa mtima kapena makumi anayi ndi asanu ndi atatu kuwongolera kugunda.

Mfundo yogwira ntchito ya rectifier circuit ya chowotcha kutentha ndi kukonza lolingana thyristor kutsegulidwa ndi kuzimitsa pa nthawi yoyenera malinga ndi lamulo linalake, ndipo potsiriza kuzindikira kutembenuka kwa magawo atatu alternating panopa mu mwachindunji panopa.

2. Kuzungulira kwa inverter ya ng’anjo yosungunula induction ndi kutembenuza mphamvu yowongoka yowongoka kuti ikhale yowonjezera ma frequency alternating panopa kuti ipereke katundu wa koyilo, kotero kuti inverter yosungunula ng’anjo iyi ndi “AC-DC-AC” ndondomeko.

Dongosolo la inverter la ng’anjo yosungunuka ya induction imagawidwa mu ng’anjo yofananira ya resonance inverter ndi gawo la resonance inverter. Dera lofananira la resonant inverter limagwiritsidwa ntchito kwambiri, ndipo pafupifupi ng’anjo zonse zosungunula zoyambilira zimagwiritsa ntchito dera lowongolera, lomwe ndi lokhwima. Choyipa ndichakuti mphamvu yamagetsi imawonjezeka ndi kuchuluka kwa ndalama, ndipo mphamvu yayikulu imakhala pafupifupi 0.9; ng’anjo yosungunuka ya inverter inverter yawonekera m’zaka khumi zapitazi, ndipo ubwino wake ndi wakuti mphamvuyo ndi yochuluka, makamaka pamwamba pa 0.95, imatha kuzindikira matupi awiri a ng’anjo akugwira ntchito nthawi imodzi, choncho amatchedwa kusungunuka kwawiri-kwa-awiri. ng’anjo mumakampani opangira maziko.

3. Pakuti kusefa kwa chowotcha kutentha, chifukwa cha kusinthasintha kwakukulu kwa voteji yokonzedwanso, m’pofunika kulumikiza inductor yaikulu mndandanda mu dera kuti ikhale yosalala, yomwe ingapangitse voteji ndi kusinthasintha kwakukulu kukhala kosavuta. Izi zimatchedwa kusefa. Inductance iyi nthawi zambiri imatchedwa riyakitala. Makhalidwe a riyakitala ndi kusunga panopa kusintha mwadzidzidzi.

Ng’anjo yosungunula induction imaperekedwa kudera la inverter kudzera mumagetsi osalala a DC mutatha kusefa. Zida za Series zimasefedwa ndi ma capacitors kuti apeze voteji yosalala.
