Izinhlobo ezimbili eziyisisekelo zokusakaza kwe-electromagnetic

Kunezinhlobo ezimbili eziyisisekelo zokusakaza kuka-electromagnetic, okuqondile nokuvundlile, futhi ukusakaza kukagesi okuma mpo kungahlukaniswa kube ukudonsa nokudonsa phansi. Njengamanje, ukulingwa kwe-electromagnetic okufakwe emkhiqizweni wezimboni ngezinga elikhulu emhlabeni wonke kucashunwe phansi. Ngakho-ke, le ncwadi yethula ngokuyinhloko umshini wokuphonsa we-electromagnetic we-aluminiyamu edonsa phansi ebheke phezulu kanye nama-alloys ayo.

8. 1. 2. 1 Idivayisi yokuphakela amandla kanye nesistimu yayo

Umshini wokuphakela amandla uyisisetshenziswa esibalulekile sokusakazwa kwe-electromagnetic, okuhlanganisa isethi yejeneretha yamafrikhwensi amaphakathi noma ukunikezwa kwamandla kagesi okuphakathi kwe-thyristor. I-Soviet Union yangaphambili, i-Hungary, i-Czech Republic, i-Germany namanye amazwe ase-Europe amukela amasethi ejeneretha aphakathi nendawo ekuqaleni, futhi isethi yamasethi akhiqiza amandla angaphonsa ingot eyodwa kuphela. Ngemuva kweminyaka yawo-1970s, amazwe anjengeSwitzerland ne-United States asebenzisa amandla kagesi e-thyristor amaphakathi kubuchwepheshe bokusakaza ngogesi kagesi, futhi isethi yezinto zikagesi zingaphonsa ama-ingots amaningi. I-thyristor intermediate frequency power supply inezinzuzo eziningi ngaphezu kwamasethi ejeneretha aphakathi nendawo, ngakho isetshenziswa kakhulu.

Umgomo wohlelo lwamandla okuphonsa ngogesi uboniswa kuMfanekiso 8-6.

Umfanekiso 8-6 Umdwebo wohlelo lwesistimu yokuphakelwa kwamandla

1-square aluminium ingot; 2-isikhunta induction ikhoyili; I-3-intermediate frequency transformer; 4-isinxephezelo capacitor;

I-5-Inverter circuit; 6-Inductor eshelelayo; 7-Ukulungisa isifunda; 8-Izigaba ezintathu ze-AC zamanje

I-thyristor intermediate frequency power supply iyisisetshenziswa esiguqula amandla ashintshashintshayo amanje abe yi-intermediate frequency alternating current. Isebenzisa isekethe yokuguqula imvamisa ye-AC-DC-AC, ebonakala ngokuba nesixhumanisi esiphakathi nendawo. Ngomjikelezo wokulungisa kabusha, amandla e-AC imvamisa yamandla aqala aguqulwa abe amandla e-DC, bese amandla e-DC aguqulwa abe amandla e-AC nge-frequency / ngokusebenzisa isekethe ye-inverter. I-thyristor intermediate frequency power supply inezinzuzo zesekethe elula, ukulungisa iphutha okulula, ukusebenza okuthembekile, nokusebenza kahle okungaphezu kwama-90%. Amadivayisi anamakhono ahlukene anamalophu okulawula ahlukene kanye nezakhiwo ezihlukene, kodwa umgomo uyafana.
