Eli nqaku liza kujonga kwiinkcukacha ze-transformer core lamination kwaye liphonononga indlela enokuziphucula ngayo iipropati zemagnethi.

Ukuphucula iiPropati zeMagnetic ngeLamination

Ii-transformer cores zihlala zakhiwa kusetyenziswa amaphepha e-laminated enziwe ngentsimbi ye-silicon. La maphepha ahlanganiswa ndawonye ukuze enze i-core, enoxanduva lokudluliselwa kwe-magnetic flux ngokufanelekileyo. Injongo ephambili yokusebenzisa i-core lamination kukunciphisa ilahleko yamandla kunye nokuphucula iipropati ze-magnetic ze-transformer. Ngokufaka i-core lamination, i-magnetic field ifumana indlela elawulwayo, inciphisa ilahleko zamandla e-eddy kwaye ivumele ukusebenza kakuhle.

Indima yeSilicon Steel kwiLamination

Intsimbi ye-silicon, ekwaziwa ngokuba yintsimbi yombane okanye intsimbi ye-transformer, yeyona nto ikhethwayo kwi-core lamination ngenxa yeempawu zayo ezibalaseleyo zemagnethi. Le alloy iqulathe intsimbi kunye ne-silicon, apho i-silicon ihlala ikhona ngeepesenti ezahlukeneyo ukusuka kwi-2% ukuya kwi-4.8%. Ukongezwa kwe-silicon kwandisa kakhulu ukumelana kombane kwentsimbi, kunciphisa ukwakheka kwemisinga ye-eddy xa ivezwa kwiindawo zemagnethi ezitshintshanayo.

Isinyithi sesilicon sinesakhiwo sekristale esahlukileyo, esiqulathe iinkozo ezilungelelaniswe ukuphucula indawo yemagnethi. Ulungelelwaniso lunciphisa ilahleko zangaphakathi ezibangelwa yi-hysteresis kunye nokuhamba komsinga we-eddy. Oku kuphucula ukuvuleka kwe-magnetic kuvumela i-magnetic flux ukuba idlule kwii-laminations nge-impedance encinci, nto leyo ekhokelela ekudlulisweni kwamandla ngokufanelekileyo.

Impembelelo yokwambathisa ubushushu

Ukuphucula ngakumbi iipropati zemagnethi ze-transformer core laminations, kufakwa i-insulating coating kumphezulu. Le coating ineenjongo ezimbini eziphambili:

Ukuba akukho nto ikhuselayo, ii-laminations ezikufutshane zinokudibana, nto leyo ebangela ukuba kubekho ii-short circuits ezithintela ukuhamba kwe-magnetic flux. I-insulating coating ithintela ukudibana ngqo phakathi kwee-laminations, nto leyo evumela ukuba i-flux ihambe ngendlela oyifunayo.

Ukuqinisekisa ukusebenza kakuhle, i-insulation coating ikhethwa ngononophelo ukuze ingathinteli ukudluliselwa kwe-magnetic flux. Ukhetho lubandakanya ukuqwalasela izinto ezifana neempawu zomzimba, ukuchasana kombane, kunye nokuqhuba kobushushu. I-polyester, i-varnish, kunye ne-epoxy coatings zihlala zisetyenziswa kwi-transformer core laminations, zibonelela ngokhuseleko lombane kunye nokukhuselwa kwiimeko zokusingqongileyo.
