Hanyar aikace-aikace na inductive Magnetic zobe| ALLAH YA KARA SAUKI

Menene hanyar amfani da zoben maganadisu inductive ? Menene bambanci tsakanin inductor Magnetic zobe kayan? Mu san shi tare.

Zobe na Magnetic abu ne da aka saba amfani da shi na hana tsangwama a cikin da'irori na lantarki, wanda ke da kyakkyawan tasiri na hana surutu, wanda yayi daidai da ƙananan tacewa. Zai iya fi dacewa da magance matsalar tsangwama mai tsayin daka na layukan wutar lantarki, layin sigina da masu haɗawa, kuma yana da jerin fa'idodi, kamar sauƙin amfani, dacewa, tasiri, ƙananan sarari da sauransu. Yin amfani da ferrite anti-tsangwama core don murkushe tsangwama na lantarki (EMI) hanya ce ta tattalin arziki, mai sauƙi da inganci. An yi amfani da shi sosai a cikin kwamfutoci da sauran kayan aikin lantarki.

Ferrite wani nau'i ne na ferrite wanda aka shirya ta hanyar amfani da kayan aikin maganadisu masu ƙarfi don kutsawa ɗaya ko fiye da sauran magnesium, zinc, nickel da sauran ƙarfe a 2000 ℃. A cikin ƙananan mitar mitar, maɓallin maganadisu na hana tsangwama yana nuna ƙarancin ƙarancin inductive kuma baya shafar watsa sigina masu amfani akan layin bayanai ko layin sigina. A cikin babban rukunin mitar, farawa daga 10MHz, haɓaka yana ƙaruwa, amma ɓangaren inductance ya kasance ƙanƙanta sosai, amma ɓangaren juriya yana ƙaruwa da sauri. lokacin da akwai ƙarfin mitar ƙarfi da ke wucewa ta cikin kayan maganadisu, ɓangaren juriya zai canza waɗannan makamashi zuwa amfani da makamashin thermal. Ta wannan hanyar, ana gina matattara mai ƙarancin wucewa, wanda zai iya rage girman siginar amo mai girma, amma ana iya yin watsi da rashin ƙarfi ga siginar mai amfani kuma baya shafar aikin al'ada na kewaye. .

Yadda ake amfani da zoben maganadisu na inductance na hana tsangwama:

1. Sanya shi kai tsaye a kan wutar lantarki ko tarin layin sigina. Domin ƙara tsangwama da sha makamashi, za ku iya kewaya shi sau da yawa akai-akai.

2. The anti-jamming Magnetic zobe tare da hawa clip dace da diyya anti-jamming suppression.

3. Ana iya ɗaure shi cikin sauƙi akan igiyar wuta da layin sigina.

4. Sauƙi da sake amfani da shigarwa.

5. An gyara nau'in katin da aka yi amfani da shi, wanda ba zai shafi cikakken hoton kayan aiki ba.

Bambanci tsakanin Materials daban-daban na Inductance Magnetic Ring

Launin zoben maganadisu gabaɗaya baki ne na halitta-baƙi, kuma saman zoben maganadisu yana da barbashi masu kyau, saboda yawancin su ana amfani da su don hana tsangwama, don haka ba kasafai ake fentin su koren ba. Tabbas ana amfani da wani dan karamin sashi nasa wajen yin inductor, sannan a rika fesa shi koren kore domin samun ingantacciyar kariya da kuma gujewa cutar da wayar da aka yi mata daidai gwargwado. Launi kansa ba shi da alaƙa da aiki. Yawancin masu amfani da yawa suna tambaya, ta yaya za a bambanta tsakanin zoben maganadisu masu girma-girma da ƙananan zoben maganadisu? Gabaɗaya, ƙaramar zoben maganadisu kore ne kuma ƙaramar zoben maganadisu na halitta ne.

Ana sa ran gabaɗaya cewa haɓakar μ I da resistivity ρ suna da girma, yayin da tilastawa Hc da asarar PC ba su da ƙasa. Dangane da fa'idodi daban-daban, akwai buƙatu daban-daban don zafin Curie, kwanciyar hankali zafin jiki, ƙimar rage ƙyalli da ƙayyadaddun ƙimar hasara.

Babban sakamakon shine kamar haka:

(1) Manganese-zinc ferrite sun kasu kashi-kashi na ferrites masu girma da kuma ƙananan ƙananan iko (wanda kuma aka sani da wutar lantarki). Babban halayen haɓakar haɓakar mn-Zn ferrite yana da ƙarfi sosai.

Gabaɗaya magana, kayan da μ I ≥ 5000 ana kiransu manyan kayan haɓakawa, kuma μ I ≥ 12000 ana buƙata gabaɗaya.

Mn-Zn babban mitoci da ƙaramin ƙarfi ferrite, wanda kuma aka sani da ikon ferrite, ana amfani da kayan aikin ferrite. Abubuwan da ake buƙata na aikin sune: haɓakar haɓakawa (gaba ɗaya da ake buƙata μ I ≥ 2000), babban zafin jiki na Curie, ƙimar bayyananniyar girma, babban ƙarfin shigar da magnetic jikewa da asarar mahimmancin maganadisu a ƙananan mitar.

Tsarin MnZn don zama kyakkyawan abu mai laushi mai laushi a cikin aikace-aikacen mitoci masu yawa. Resistivity ρ yana da girma kamar 108 ω m kuma babban asarar mitar ƙananan ƙananan ne, don haka ya dace musamman don babban mita 1MHz da 300MHz, kuma Curie zafin jiki na kayan NiZn ya fi MnZn, Bs kuma har zuwa 0.5T 10A / m HC na iya zama ƙanƙanta kamar 10A/m, don haka ya dace da kowane nau'in inductor, masu canza wuta, matattara mai tacewa da coils na shaƙa. Ni-Zn high-frequency ferrites suna da faɗin bandwidth da ƙarancin watsawa, don haka galibi ana amfani da su azaman katsalandan na lantarki (EMI) da tsangwama na mitar rediyo (RFI) don haɗa manyan tsangwama na wutar lantarki (EMI) da na'urori masu hawa saman. Babban mitar iko da tsangwama.
