Izidingo zokuncibilikisa isithando somlilo wesifunda sokuqala
Umsebenzi wesekethe yokuqalisa ye- ukuchithwa kwesithando somlilo ukukhiqiza ukushaywa kwesango okuhlangabezana nezimfuneko zokuqinisekisa ukuthi isithando somlilo esincibilikayo siyashintsha kusukela ekuvinjelweni kuya kokwenza ngesikhathi esidingekayo. Ngokubanzi, isifunda se-trigger sokuncibilika kwesithando somlilo sivame ukufaka isifunda sokulawula isigaba esilawula isikhathi sokuqala.
Isifunda sokuqala se-induction melting furnace kufanele sihlangabezane nalezi zidingo ezilandelayo:
Ububanzi be-pulse pulse kufanele buqinisekise ukuthi isithando somlilo esincibilikayo singavulwa. Isiguquli esinemithwalo ye-inductive kanye ne-back-EMF kufanele senziwe yi-pulse-frequency pulse noma isitimela se-pulse. Ububanzi obungaphezu kuka-30º, isigaba sesithathu sebhuloho esilawulwa ngokuphelele kufanele sisebenzise ububanzi obungaphezu kuka-60º noma sisebenzise amapulse amancane amancane ahlukaniswe ngama-60º.
I-pulse ye-trigger kufanele ibe ne-amplitude eyanele. Ngezikhathi ezibandayo zangaphandle, ubukhulu be-pulse current kufanele benyuswe bube izikhathi eziphindwe ka-3-5 ubukhulu bamanje bensimbi, futhi ukuqina kwengaphambili lokushaya kufanele futhi kukhuphuke, ngokuvamile kufinyelela ku-1-2A / μs.
I-pulse ye-trigger enikeziwe akufanele yeqe amandla we-voltage, wamanje namandla esango lesithando somlilo esincibilikayo, futhi kufanele ibe ngaphakathi kwendawo enokwethenjelwa yezimpawu zesango volt-ampere.
Kufanele kube nokusebenza okuhle kokuphazamisa, ukuqina kwezinga lokushisa nokuhlukaniswa kukagesi kusuka kusifunda esikhulu.
Isithombe esingezansi sibonisa isifunda esivamile se-trigger sokungeniswa kwesithando somlilo
Yakhiwe izingxenye ezimbili: isixhumanisi se-pulse amplifying esakhiwa i-V1 ne-V2, nesixhumanisi sokubala se-pulse esakhiwa i-pulse transformer TM nesekethe elisizayo. Lapho i-V1 ne-V2 ivuliwe, i-pulse transformer isetshenziselwa ukukhipha i-pulse pulse phakathi kwesango ne-cathode yesithando somlilo esincibilikayo. I-VD1 ne-R3 isethelwe i-pulse transformer TM ukuthi ikhiphe amandla ayo agciniwe lapho i-V1 ne-V2 ziguquka ukusuka phambili kuye ekucimeni.
