Isithando somlilo esiphakathi nendawo

Isithando somlilo sefrikhwensi emaphakathi SEBENZISA amandla kagesi wefrikhwensi emaphakathi ukuze kushiswe, ukuncibilika kanye nokugcina ukushisa.Isithando somlilo esiphakathi sisetshenziselwa ikakhulukazi ukuncibilikisa insimbi ye-carbon, i-alloy steel, uhlobo lwensimbi, kodwa futhi ingasetshenziselwa ithusi, i-aluminium nokunye ukuncibilikisa insimbi okungeyona ayoni kanye nokukhulisa izinga lokushisa.Usayizi omncane, isisindo esincane, izinga eliphezulu, ukusetshenziswa kwamandla aphansi. , ukuncibilika okusheshayo, ukulawula ukushisa kwesithando somlilo kulula, ukukhiqiza okuphezulu.Isithando somlilo esiphakathi nendawo ngokuvamile sisetshenziselwa ukukhishwa kwefekthri nokwelashwa kokushisa.Isithando somlilo esiphakathi nendawo kancane kancane siye sashintsha isithando somlilo samalahle, isithando somlilo segesi, isithando somlilo sikawoyela kanye nesithando somlilo esivamile sokumelana nokushisa, futhi sesiyintandokazi entsha ekubunjweni kwefekthri nokwelashwa kokushisa.Isimiso sokusebenza kwesithando somlilo esiphakathi nendawoIsithando somlilo esiphakathi nge-silicon controlled rectifier inverter ukukhiqiza okuphakathi. amandla emvamisa, athunyelwa kukhoyili yomzimba wesithando somlilo, isithando somlilo (ikhoyili) maphakathi nenkundla ye-medium frequency frequency electromagnetic, ukuze insimbi esesithandweni somlilo ikhiqize i-eddy current, eddy current bese yenza insimbi ikhiqize inani elikhulu lokushisa ukuthi ukuncibilika kwensimbi.Isithando somlilo esiphakathi nendawo sakhiwe ngokuyinhloko ukuphakelwa kwamandla, indandatho yokungeniswa kanye ne-crucible eyenziwe ngezinto eziphikisayo endandatho yokungeniswa.Ngaphakathi kwe-crucible equkethe ishaja yesithando somlilo sensimbi, elingana nesiguquli esimazombezombe ngasinye, ikhoyili yokungeniswa, uma inamandla e-ac, ukuze khiqiza inkambu kazibuthe eshintshanayo kukhoyili yokungeniswa, ulayini wamandla kazibuthe kushaja yesithando somlilo esishisayo, insimbi ikhiqizwa kumandla we-electromotive induction charge yesithando somlilo, ngenxa yomthwalo ngokwawo yenza iluphu evaliwe, iphuzu lalokhu kuguquka kwesithando kungukujika kuphela futhi kuvaliwe.Ngakho-ke, i-inductive current ikhiqizwa kanyekanye enkokhelweni.Lapho i-current induced idlula enkokhelweni, ukushaja kuyashiswa ukuze kuncibilike.Inqubo yokusebenza yesithando somlilo esiphakathi nendawo nayo iwuhlobo lwe-induction cooker, ngale ndlela elandelayo: okokuqala, ngokusebenzisa ugesi we-inverter, ukushintshwa kwezigaba ezintathu. isilungisi samanje (SCR) sibe yisigaba esisodwa se-dc, bese nge-inverter yebhuloho inverter ibe ohlotsheni lwamanje olushintshayo (ac), 500-1000 hz imvamisa ishayela ngokwakhiwa kwendandatho yethusi endaweni kazibuthe yesithando somlilo, yenza insimbi yesiyingi ikhiqize i-eded current. inkambu kazibuthe, i-eddy current igeleza ngensimbi eshisayo, ikhiqize ukushisa, ukuze kufinyelelwe umgomo wokuncibilika kwensimbi.Imvamisa evamile yesithando somlilo sikagesi esiyifrikhwensi ephakathi ngu-800-20000Hz.Okubili, umdwebo wesimiso sokusebenza kwesithando somlilo ophakathi nendawoUmdwebo webhlokhi yesifunda esikhulu umshini ukhonjiswe emfanekisweni.I-rectifier isebenzisa isekethe ye-rectifier elawulwa yibhuloho enezigaba ezintathu, i-inverter ithatha isifunda se-inverter yesigaba esisodwa, umthwalo uyifomu elifana ne-resonant, isixhumanisi sokuhlunga se-DC siwukuhlunga okukhulu kwe-inductance, ukuze kuhlangatshezwane izidingo zokufakwayo zama-inverter ahambisanayo.

Isekhithi yesilungisi elawulwa yibhuloho lezigaba ezintathu

Amandla kagesi okukhiphayo wesekethe yesigaba ezintathu elawulwa kabusha elawulwa yibhuloho yilena: Ud = 2.34 U2cosa…(1)Ud inani elimaphakathi le-voltage ephumayo ye-DCU2 — Isigaba sikagesi segridiA — I-Angle yesigaba sokucuphaUkwakheka kwegagasi kwe-voltage ephumayo kuma-engeli A ahlukene (ngaphansi komthwalo we-inductive kanye nomthamo onganqamuki).Isimo sokuthi a>Isimo esingu-90° sibizwa ngokuthi isimo sokusebenza esiphendukile sokulungiswa, okuyisisekelo saso siwukuthi umthwalo ubuyisela amandla kugridi yamandla.
