Zolakwika wamba ndi njira zothetsera mavuto zida mkulu pafupipafupi kuzimitsa
Zolakwika zofala ndi njira zothetsera mavuto za zida zotseketsa pafupipafupi
1. Zowonongeka Zowonongeka Zida zozimitsa zowonongeka zimagwira ntchito bwino koma mphamvu sizikukwera.
Ngati zidazo zimagwira ntchito bwino, zikhoza kutanthauza kuti mphamvu ya chigawo chilichonse cha chipangizocho ndi chokhazikika, ndipo zikutanthauza kuti kusintha kosayenera kwa magawo a zidazo kudzakhudza mphamvu ya zipangizo.
Zifukwa zazikulu ndi izi:
(1) Gawo la rectifier silinasinthidwe bwino, chubu chowongolera sichimatsegulidwa kwathunthu ndipo magetsi a DC safika pamtengo wovomerezeka, womwe umakhudza kutulutsa mphamvu;
(2) Ngati mtengo wamagetsi wapakati umasinthidwa kwambiri kapena wotsika kwambiri, umakhudza mphamvu yamagetsi;
(3) Kusintha kosayenera kwa mtengo wodulidwa ndi wodulidwa kumapangitsa kuti mphamvu ikhale yochepa;
(4) Kusagwirizana pakati pa ng’anjo yamoto ndi magetsi kumakhudza kwambiri mphamvu yamagetsi;
(5) Ngati capacitor yamalipiro imakonzedwa mochuluka kwambiri kapena pang’ono, mphamvu yamagetsi yokhala ndi magetsi abwino kwambiri komanso kutentha kwamafuta sikungatheke, ndiko kuti, mphamvu yabwino kwambiri yachuma sichingapezeke;
(6) Inductance yogawidwa yapakatikati yotulutsa ma frequency frequency and inductance yowonjezera ya resonant circuit ndi yayikulu kwambiri, yomwe imakhudzanso mphamvu yayikulu kwambiri.
2. Zowonongeka Zowonongeka Zida zozimitsira maulendo apamwamba zikuyenda bwino, koma mphamvu ikakwera ndikutsitsidwa mu gawo lina la mphamvu, zidazo zimakhala ndi phokoso lachilendo ndi kugwedezeka, ndipo chida chamagetsi chimasonyeza kugwedezeka.
Cholakwika chamtunduwu nthawi zambiri chimachitika pa mphamvu yopatsidwa potentiometer, ndipo gawo lina la mphamvu yopatsidwa potentiometer silidumpha bwino, zomwe zimapangitsa kuti inverter igubuduze ndikuwotcha thyristor pomwe zida sizikhazikika komanso zowopsa.
