Lisebelisoa tsa maqhubu a mahareng a inverter li tlameha ho ba le melemo ho feta libono tsa maqhubu a mahareng a parallel
Inverter intermediate frequency furnaces e tlameha ho ba le melemo ho feta parallel intermediate frequency furnaces
1. The thyristor parallel circuit ke parallel resonance intermediate frequency sebōpi. Nakong ea ts’ebetso ea ho qhibiliha, haholo-holo bakeng sa ho qhibiliha aluminium, koporo le lisebelisoa tse ling, mojaro o bobebe haholo, ‘me matla a eona a matla a nyenyane haholo, a amanang haholo le tlhaho ea mojaro, kahoo lebelo la ho qhibiliha ha lona le lieha , Bothata. ka ho futhumatsa. The thyristor letoto la intermediate frequency melting sebōpi fetola matla ka frequency modulation, kahoo e batla e fokolang angoa ke mofuta oa mojaro. Ts’ebetso eohle ea ho qhibilihisa e batla e boloka matla a sa khaotseng. Hobane ke letoto la resonance, ke hore, voltage resonance, voltage induction coil e phahame mme ea hona joale e nyane, ka hona Tahlehelo ea matla e nyane.
2. Hobane ke letoto la inverter, matla a matla a phahame ‘me li-harmonics li nyenyane, kahoo ha ho hlokahale ho kenya sesebelisoa sa matšeliso a matla a sebetsang. Sena se ka bolokela basebelisi chelete e ngata, hape ke sesebelisoa se tsoetseng pele seo lefapha la phepelo ea motlakase le se khothalletsang ka matla.
3. Ha letoto la sebōpi sa maqhubu a mahareng a ntse a sebetsa, rectifier e lula e sebetsa maemong a felletseng, ‘me matla a phallo ea potoloho ea inverter a fetoloa ka ho laola maqhubu a motlakase oa inverter trigger pulse. ‘Me mojaro oa hona joale ke leqhubu la sine, kahoo letoto la sebōpi sa maqhubu a mahareng le ke ke la silafatsa marang-rang a matla ka li-harmonics tse phahameng,’ me matla a matla a phahame. Li-inverter tse tšoanang li ke ke tsa fihlela ts’ebetso ea othomathike e le ‘ngoe ho isa ho tse peli, hobane phetoho ea matla ea phepelo ea motlakase e ts’oanang e ka finyelloa feela ka ho lokisa matla a phallo ea borokho bo nchafatsang. Ha borokho ba parallel inverter rectifier bo sebetsa ka voltage e tlase, sekhutlo sa rectifier conduction se nyane haholo. Naheng, matla a lisebelisoa a tla be a le tlase haholo, ‘me motlakase oa inverter o tšoanang ke leqhubu la lisekoere, le tla silafatsa gridi ka botebo. Haeba matla a feto-fetoha ka ho fetola inverter mokokotlo oa khatello ea mokokotlo, sebaka sa phetoho ea matla se moqotetsane haholo. Ka hona, lisebelisoa tsa motlakase tsa inverter tse tšoanang li ke ke tsa fihlela ts’ebetso e le ‘ngoe ho isa ho tse peli.
