Yoqobo: Ukukhanya kwezixhobo
Umsebenzi osisiseko we-inductance kwiisekethe kukucoca, ikakhulu ekucutshungulweni kwesignali. Kutheni kukho iimfuno zomgama wokhuseleko xa kusenziwa isiqinisekiso? Eli nqaku liza kunika iimpendulo ezifanelekileyo kulo mbuzo.
Enyanisweni, kwiisekethe eziqhelekileyo, akukho mfuneko icacileyo yomgama wokhuseleko lwee-inductors. Zifuna kuphela ukuhlangabezana neemfuno ezisisiseko zokufakelwa kwe-voltage, kwaye imveliso ayizukuhamba i-short circuit emva kokusebenza ixesha elide.
Xa sivavanya ii-inductors, sihlala sivavanya ukumelana kwe-voltage yee-windings ukuya kwii-windings okanye ii-windings ukuya kwii-magnetic cores, ngokuqhelekileyo malunga ne-500VAC.
Nangona kunjalo, ukuba ii-inductors zisetyenziswa kwiimeko zesekethe ezine-voltage ephezulu, kuya kwahluka. Kwiisekethe ezine-voltage ephezulu, isithuba phakathi kwee-inductor pins sidla ngokufuna ukuthobela imigangatho yokususwa kombane kunye nomgama wokuqhekeka ukuze kuthintelwe ii-short circuits okanye ukukhutshwa.
Ngokwemigangatho ye-IEC60950, amanqanaba ahlukeneyo e-voltage ahambelana nomgama omncinci owahlukileyo. Xa isekethe ye-voltage ye-400V ingafakwanga, umsantsa wombane phakathi kwee-inductor pins kufuneka ube yi-≥ 6.4mm.
Ngokuphathelele umgama we-creepage, kwiisekethe ze-220V, umgama we-creepage we-FR4 substrate kufuneka ube yi-≥ 4.0mm. Kwii-inductors ze-high-voltage, ezifana nezo zisecaleni kwe-transformer ephambili yombane otshintshayo, umgama we-insulation oqinisiweyo we-≥ 8.0mm uyafuneka.
Xa ubushushu bokusebenza be-inductor buphezulu, umgama wokhuseleko unokwandiswa ngokufanelekileyo ukuze kulungiswe ukuguga kwezinto zokukhusela ezibangelwa kukusetyenziswa kwexesha elide kwe-inductor.
Kwinkqubo yoyilo lwesekethe, ukuba umgama wokuhambahamba awonelanga, i-slotting ingasetyenziselwa ukuhlangabezana neemfuno. Ukukhetha izixhobo ze-inductor, kuyimfuneko ukusebenzisa i-skeleton engatshiyo nengatshiyo, ucingo olune-enamel olumelana nobushushu obuphezulu, kunye neteyiphu yokukhusela eqinisekisiweyo yokhuseleko ukuqinisekisa ukuthotyelwa kwemigangatho neemfuno zokhuseleko.
Ngokubanzi, imfuneko yomgama wokhuseleko kwii-inductors ngokuyintloko kukuthintela iingozi zokhuseleko ezibangelwa kukonakala kombane, ukuvuza, kunye nokungaphumeleli kokufakelwa kwezinto. Oku kunokubhekisa kwimigangatho efana ne-IEC 60950 kunye ne-UL 60950, kwaye yenzelwe ngokupheleleyo ngokusekelwe kumanqanaba ombane, iindawo zokusebenza, kunye neempawu zezinto ukuqinisekisa ukupasa kovavanyo kunye nesatifikethi.
