Okwangempela: Ukukhanya Kwamadivayisi
Umsebenzi oyisisekelo wokungenisa umoya emasekethe ukuhlunga, ikakhulukazi ukucubungula isignali. Kungani kunezidingo zebanga lokuphepha lapho kwenziwa isitifiketi? Lesi sihloko sizonikeza izimpendulo ezifanele kulo mbuzo.
Eqinisweni, kumasekethe ajwayelekile, akukho mfuneko ecacile yebanga lokuphepha lama-inductor. Adinga kuphela ukuhlangabezana nezidingo eziyisisekelo zokufakwa kwe-voltage, futhi umkhiqizo ngeke unciphise isekethe ngemva kokusebenza kwesikhathi eside.
Lapho sihlola ama-inductor, sivame ukuhlola ukumelana kwamandla kagesi kwama-windings kuma-windings noma ama-windings kuma-magnetic cores, ngokuvamile cishe angu-500VAC.
Kodwa-ke, uma ama-inductor esetshenziswa ezimweni zesekethe enamandla aphezulu, kuzohluka. Ezisekethe ezinamandla aphezulu, isikhala phakathi kwamaphini e-inductor sivame ukudinga ukuhambisana nezindinganiso zokuhlanzwa kukagesi kanye nebanga lokuhamba ukuze kugwenywe amasekethe amafushane noma ukukhishwa.
Ngokwezinga le-IEC60950, amazinga ahlukene kagesi ahambisana namabanga aphansi ahlukene. Uma isekethe yegesi engu-400V ingafakwanga, igebe likagesi phakathi kwezikhonkwane ze-inductor kumele libe ngu-≥ 6.4mm.
Ngokuphathelene nebanga lokucwila, kumasekethe angu-220V, ibanga lokucwila le-substrate ye-FR4 kudingeka libe ngu-≥ 4.0mm. Kuma-inductor ane-voltage ephezulu, njengalawo aseduze ne-transformer eyinhloko yokunikezwa kwamandla okushintsha, ibanga lokufakwa kokushisa eliqinisiwe elingu-≥ 8.0mm liyadingeka.
Uma izinga lokushisa lokusebenza le-inductor liphezulu kakhulu, ibanga lokuphepha lingakhuliswa ngokufanele ukuze kulungiswe ukuguga kwezinto zokuvikela ezibangelwa ukusetshenziswa kwesikhathi eside kwe-inductor.
Enkambisweni yokuklama isekethe, uma ibanga lokuhamba linganele, ukufaka izikhala kungasetshenziswa futhi ukuhlangabezana nezidingo. Ekukhetheni izinto zokufaka i-inductor, kuyadingeka ukusebenzisa uhlaka olungashisi umlilo nolungashisi, ucingo olune-enamel olumelana nokushisa okuphezulu, kanye netheyiphu yokuvikela eqinisekisiwe yokuphepha ukuqinisekisa ukuhambisana nezindinganiso nezidingo zokuphepha.
Sekukonke, imfuneko yebanga lokuphepha lama-inductors iwukuvimbela izingozi zokuphepha ezibangelwa ukuphuka kukagesi, ukuvuza, kanye nokwehluleka kokufakwa kokushisa. Lokhu kungabhekisela ezindinganisweni ezifana ne-IEC 60950 kanye ne-UL 60950, futhi kuklanywe ngokuphelele ngokusekelwe emazingeni kagesi, izindawo zokusebenza, kanye nezici zezinto ukuqinisekisa ukuphasiswa kokuhlolwa kanye nesitifiketi.
