Iluphi uhlobo lokunikezwa kwamandla okuvama okumaphakathi okungahlangabezana nezidingo ze isithando somlilo esincibilikisa induction?

1 Izidingo zamandla okukhiphayo zesithando somlilo esincibilikayo se-thyristor esiphakathi nendawo yamandla kagesi.

Amandla okukhiphayo we-thyristor intermediate frequency power supply kumele ahlangabezane namandla amakhulu esithando somlilo esincibilikayo, futhi amandla okukhiphayo angalungiswa kalula. Lokhu kungenxa yokuthi impilo ye-crucible yesithando somlilo se-induction ngokuvamile imayelana namashumi eziko futhi iyalimala. Ukufakwa kwesithando somlilo we-crucible kumele kwakhiwe kabusha, futhi ngemva kokwakhiwa kwesithando somlilo esisha, ihhavini lamandla aphansi kufanele lenziwe kuso.Ngokuvamile, isithando somlilo siqala kusuka ku-10-20% wamandla alinganiselwe, bese ukwandisa amandla 10% ngezikhathi ezithile kuze kube amandla alinganiselwe. Ngaphezu kwalokho, enkambisweni yesithando somlilo, lapho ukushaja kuncibilika, ukwakheka kwenkokhelo kufanele kuhlolwe. Ngesikhathi sokuhlolwa, ukuze kuvinjwe ukushajwa ekuncibilikeni nasekubileni ngamandla, ukunikezwa kwamandla okuvama okumaphakathi kufanele kunciphise amandla okukhiphayo ukuze kugcinwe ukushaja kufudumele. Ngokubuka lesi simo esingenhla, kuyadingeka ukuthi ukunikezwa kwamandla kagesi okuphakathi kwe-thyristor kungalungiswa kalula ukusuka ku-10% -100% wamandla okukhiphayo alinganiselwe. Isithando somlilo esisetshenziselwa ukukhanga asinayo inqubo yokubhaka.

2 Izidingo zefrikhwensi yokuphuma kwesithando somlilo esincibilikayo se-thyristor intermediate frequency power supply.

Ubudlelwano phakathi kokusebenza kahle kukagesi kanye nemvamisa yesithando somlilo esincibilikayo kuhlobene. Kusukela ekusebenzeni kahle kukagesi, imvamisa yokuphuma kwe-thyristor intermediate frequency power supply inganqunywa. Isibonelo, lokhu sikubiza ngokuthi fo. I-inductor empeleni iyikhoyili ye-inductive, futhi ukuze kunxeshezelwe amandla asebenzayo ekhoyili, i-capacitor ixhunywe ngokuhambisana kuzo zombili iziphetho zekhoyili, eyenza isekethe ye-LC oscillating. Lapho i-frequency ephumayo f ye-inverter ye-thyristor ilingana nemvamisa ye-oscillation yemvelo fo ye-loop yokuncibilika kwesithando somlilo, khona-ke isici samandla se-loop silingana no-1. Amandla aphezulu azotholakala esithandweni sokuncibilika se-induction. Kungabonakala kulokhu okungenhla ukuthi imvamisa ye-oscillation yemvelo ye-loop ihlobene namanani we-L no-C. Ngokuvamile, inani le-capacitor C yesinxephezelo lihleliwe, kuyilapho i-inductance L ishintsha ngenxa yokushintshwa kwe-capacitor C. i-permeability coefficient yento yesithando somlilo. I-permeability coefficient μ yensimbi yesithando somlilo inkulu kakhulu, ngakho-ke i-inductance L inkulu, futhi lapho izinga lokushisa lensimbi liphakeme kunephuzu le-Curie, i-coefficient yokungena engu-μ=1 yensimbi, ngakho-ke i-inductance L iyancipha, iluphu yesithando somlilo esincibilikayo sokungeniswa Imvamisa ye-oscillation yemvelo izoshintsha ukusuka kokuphansi kuye phezulu. Ukuze wenze isithando somlilo sokuncibilikisa ngaso sonke isikhathi sithole amandla amakhulu ngesikhathi senqubo yokuncibilikisa, lokhu kudinga ukuthi ifrikhwensi yokuphumayo kagesi yefrikhwensi ephakathi ye-thyristor ingashintsha ngokushintsha kwe-fo, futhi njalo ugcine i-frequency ilandelela ngokuzenzakalelayo.

3 Ezinye izimfuneko zokunikezwa kwamandla kagesi okuphakathi kwe-thyristor.

Lokhu kungenxa yokuthi lapho ukushaja kwesithando somlilo kuncibilika, uma ukunikezwa kwamandla okuvama okumaphakathi kwehlulekile, i-crucible izolimala ezimeni ezinzima. Ngakho-ke, i-thyristor intermediate frequency power supply iyadingeka ukuze isebenze ngendlela enokwethenjelwa, futhi kufanele futhi ibe nesivikelo esidingekayo sokunciphisa umkhawulo we-voltage, isivikelo se-over-voltage kanye ne-over-current, kanye nokunqanyulwa kwamanzi. Ukuvikela, namanye amadivaysi okuvikela okuzenzakalelayo. Ukwengeza, kuyadingeka ukuthi i-thyristor intermediate frequency power supply ibe nezinga eliphezulu lempumelelo yokuqala, futhi ukusebenza kokumisa kufanele kube lula.
