Incazelo yomkhiqizo
An indandatho yokushisisa kagesiiyidivayisi esebenzisa inkambu ye-electromagnetic ukushisa into. Iqukethe ikhoyili eqhubayo kanye nomthombo wamandla we-AC, futhi isebenzisa inkambu kazibuthe ekhiqizwa amandla amanje entanjeni ukushisa into. Emkhiqizweni wezimboni kanye nempilo yansuku zonke, isetshenziselwa kakhulu ukushisa uketshezi, okuqinile, namagesi, futhi inezinzuzo eziningi ezifana nokusebenza kahle okuphezulu, ukuphepha, nokuvikelwa kwemvelo.
Ngokombono wesimiso sokusebenza, indandatho yokushisisa ye-electromagnetic isebenzisa inkambu kazibuthe ekhiqizwa lapho intambo kagesi inikwa amandla okuxhumana nemigqa kazibuthe eguquguqukayo eyakhiwe intambo ngokwayo ukuze kuzuzwe ukushisa. Lapho i-current edlula ocingweni ishintsha, i-flux kazibuthe yenkundla kazibuthe nayo iyashintsha, okuholela kumanje owenziwe eduze kocingo. Ngokomthetho kaFaraday wokungeniswa kukazibuthe, amandla akhona ocingweni akhiqiza inkambu kazibuthe, ebese isebenzisana nekazibuthe ekhiqizwa amandla asetshenziswayo ukuze kushiswe ucingo. Le ndlela yokushisisa ibizwa ngokuthi i-Joule heat.
Indandatho yokushisisa ye-electromagnetic inezinzuzo eziningi, ngale ndlela elandelayo:
♦ 1.Ukushisa kwalo mphumela muhle kakhulu. Njengoba ukushisisa kwe-electromagnetic kushisa into ngokusebenzisana kwenkundla kazibuthe ocingweni kanye nolayini ozibuthe oguquguqukayo owenziwe intambo ngokwayo, ubude nokuma kocingo kungaklanywa ngokunengqondo kakhudlwana, okwenza umthelela wokushisa ufane futhi usebenze kahle.
♦ 2.Isivinini sokushisisa siyashesha kakhulu. Ngenxa yokuthi inkambu kazibuthe ekhiqizwe ucingo isebenzisana nomugqa ozibuthe oguquguqukayo owakhiwe ucingo ngokwalo, isivinini sokushisa siyashesha, futhi into ingashiswa ngokushesha ekushiseni okumisiwe.
♦ 3.Inqubo yokushisisa iphephe kakhulu. Njengoba ukushisisa kwe-electromagnetic kushisa into ngokusebenzisana kwenkundla kazibuthe ocingweni ngomugqa ozibuthe oguquguqukayo owenziwe intambo ngokwayo, ngeke kube khona ilangabi elivulekile nendawo yokushisa ephezulu, ukugwema ingozi yomlilo nokusha.
♦ 4.Ingakwazi futhi ukuzuza ukonga amandla kanye nokuvikelwa kwemvelo. Ngenxa yomphumela wayo omuhle wokushisa kanye nesivinini sokushisa esisheshayo, kunganciphisa ukusetshenziswa kwamandla futhi kunciphise ukungcoliswa kwemvelo.
Mayelana nokusetshenziswa, izindandatho zokushisa zikagesi zinezinhlobonhlobo zokusetshenziswa kuzo zombili izimboni nempilo yansuku zonke. Emkhakheni wezimboni, ingasetshenziswa ukushisisa izinto zensimbi ezifana nensimbi ne-aluminium alloys, futhi isetshenziswe ezinqubweni ezifana nokwelashwa kokushisa, ukuncibilika, nokucwilisa. Lokhu akuthuthukisi ukusebenza kahle kokukhiqiza kuphela kodwa futhi kuthuthukisa ikhwalithi yomkhiqizo. Ezimpilweni zansuku zonke, izindandatho zokushisisa i-electromagnetic zisetshenziswa ekushiseni izitofu nasezitsheni zokungeniswa emakhishini asendlini. Uma ziqhathaniswa nezitofu zegesi ezivamile, ziphephile, zisebenza kahle kakhulu, futhi aziyigcini imvelo. Ngaphezu kwalokho, futhi idlala indima ebalulekile emikhakheni efana nokunakekelwa kwezempilo, i-metallurgy, nobunjiniyela bamakhemikhali.
Amashadi ashisayo: indandatho yokushisa kagesi, abahlinzeki bendandatho yokushisa yaseChina
