Menene inductor gama gari | ALLAH YA KARA SAUKI

Kamar resistors da capacitors, masu gabatarwa na ɗaya daga cikin na'urorin da aka fi amfani da su a ƙirar da'ira. Inductor wani sinadari ne na ajiyar makamashi, wanda zai iya jujjuya makamashin lantarki da makamashin maganadisu zuwa juna, kuma galibi yana taka rawa wajen tacewa, girgizawa, daidaita halin yanzu da kuma hana kutsewar wutar lantarki a cikin kewaye. Lokacin da ake amfani da inductor a cikin wannan da'ira, dole ne ku san waɗannan sigogi na inductor!

Lokacin da ka kalli wasu ƙirar ƙirar da'ira, za ka ga ana amfani da alamun inductance a cikin da'ira. Bayan na kalli sigogi akan alamar, na ƙara rikicewa. Yaushe sashin inductor ya zama OHM? A gaskiya, wannan ba inductor ba ne, amma ƙirar maganadisu. Na gaba, za mu ƙara wasu ilimi game da bambanci da haɗin kai tsakanin inductor da beads na maganadisu.

Da farko bayyana aikin magnetic beads a cikin da'ira, mafi girman aikin jerin gwano na maganadisu a cikin layin watsa siginar shine kashe siginar tsangwama, daga mahangar ra'ayi, ƙwanƙolin maganadisu na iya zama daidai da inductor, lura cewa wannan. inductor ne mai sauƙi. Ainihin inductor coil ya rarraba capacitor, wato, inductor da muke amfani da shi yana daidai da inductor da aka haɗa a layi daya tare da capacitor da aka rarraba.

Bayanin Inductance

A ka'ida, don kashe siginar tsangwama da aka gudanar, ana buƙatar cewa mafi girman adadin inductance, mafi kyau, amma ga inductor nada , mafi girma da inductance, mafi girma da rarraba capacitance na inductor coil, da kuma sakamakon biyun. za a soke juna fita.

A farkon, haɓakar inductor yana ƙaruwa tare da haɓakar mitar, amma lokacin da haɓakarsa ya ƙaru zuwa matsakaicin, haɓakawar yana raguwa da sauri tare da haɓakar mitar, wanda ke faruwa saboda tasirin daidaitaccen ƙarfin da aka rarraba. Lokacin da impedance ya ƙaru zuwa matsakaicin, shine wurin da rabon iyawar inductor na coil ɗin inductor ke daidaita tare da daidaitaccen inductor a layi daya. Mafi girman inductance na inductor coil shine, ƙananan mitar resonant shine. Idan muna son ƙara haɓaka mitar dannewa, to zaɓin ƙarshe na inductor coil ɗin zai zama mafi ƙarancin iyakarsa, ƙwanƙwasa maganadisu, wato, inductor ta hanyar zuciya, na'urar inductor ce mai ƙasa da juyi 1. Koyaya, ƙarfin da aka rarraba na inductor ta hanyar-core yana sau da yawa zuwa sau da yawa ƙasa da na na'urar inductor mai madauki guda ɗaya, don haka mitar aiki na inductor ta hanyar zuciya ya fi na inductor ɗin madauki guda ɗaya. . Inductance na maganadisu beads gabaɗaya ƙanƙanta ne, game da tsakanin ƴan microbeads da yawa. Wani abin da ake amfani da shi na Magnetic beads shi ne yin garkuwar electromagnetic, tasirinsa na garkuwar lantarki ya fi tasirin garkuwar waya, wanda mafi yawan mutane ba sa kula sosai. Hanyar da ake amfani da ita ita ce barin wayoyi guda biyu su wuce ta tsakiyar ƙwanƙolin maganadisu, don haka idan akwai wutar lantarki da ke gudana daga cikin wayoyi biyu, mafi yawan filin maganadisu zai kasance cikin maɗaukakiyar maganadisu, da kuma Magnetic beads. filin ba zai ƙara haskaka waje ba. Domin filin maganadisu yana samar da eddy current a cikin ƙwanƙolin maganadisu, alkiblar eddy ɗin da ke samar da layin wutar ya yi daidai da na layin wutar da ke saman madubin, wanda zai iya fuskantar juna. Don haka ma’aunin maganadisu shi ma yana da tasirin kariya ga wutar lantarki, wato Magnetic bead yana da tasirin kariya mai qarfi akan filin lantarki da ke cikin madugu.

Fa'idar yin amfani da beads na maganadisu don garkuwar lantarki shi ne cewa ƙwanƙolin maganadisu ba sa buƙatar ƙasa, kuma ana iya guje wa matsalar ƙasa da wayar garkuwa ke buƙata. Yin amfani da beads na maganadisu azaman garkuwar wutan lantarki, don wayoyi biyu, daidai yake da haɗa inductor na danne yanayin gama gari a cikin layi, wanda ke da tasiri mai ƙarfi na kashewa akan siginonin tsangwama na gama gari.

Ana iya ganin cewa inductor coil an fi amfani da shi don EMI nannen ƙananan siginar tsangwama, yayin da ƙwanƙwasa maganadisu galibi ana amfani da su don EMI nanne siginar tsangwama mai tsayi. Don haka, don mannewar EMI na siginar tsangwama mai faɗi, dole ne a yi amfani da inductor da yawa na kadarori daban-daban a lokaci guda don yin tasiri. Bugu da ƙari, don murkushe yanayin gama gari da aka gudanar da siginar tsangwama ta EMI, ya kamata mu kuma kula da murkushe matsayin haɗin gwiwa tsakanin inductor da Y capacitor. Y capacitor da suppression inductor ya kamata su kasance kusa da shigar da wutar lantarki, wato, matsayi na tashar wutar lantarki, kuma inductor mai girma ya kamata ya kasance kusa da Y capacitor, yayin da Y capacitor. ya kamata ya kasance kusa da kusa da wayar da aka haɗa da ƙasa (wayar ƙasa na igiyar wutar lantarki mai mahimmanci uku), wanda ke da tasiri ga EMI suppression.

Abin da ke sama shine gabatarwar inductor gama gari, idan kuna son ƙarin sani game da inductor, da fatan za ku iya tuntuɓar mu.
