1. anti-tsangwama da electromagnetic karfinsu
1. Ma'anar kutsawa
Tsangwama na nufin hargitsin da hayaniya ta waje ke haifarwa da igiyar wutar lantarki mara amfani a cikin karɓar ƙirar crystal na ruwa.Hakanan za'a iya bayyana shi azaman tasirin tashin hankali da kuzarin da ba'a buƙata ya haifar, gami da tasirin wasu sigina, fitar da batsa, hayaniya ta wucin gadi, da sauransu.
2.Daidaitawar lantarki da tsangwama
A gefe guda, kayan aikin lantarki da na'urorin lantarki ta hanyar tsoma baki na waje, a daya bangaren, zai haifar da tsoma baki ga duniyar waje.Saboda haka, siginar lantarki sigina ce mai amfani ga kewaye, kuma wasu da'irori na iya zama hayaniya.
Fasahar hana tsangwama na da'irar lantarki wani muhimmin sashi ne na EMC.EMC yana nufin e lectro MAG wani abu netic Compatibility, wanda ke fassara azaman Daidaituwar lantarki.Daidaitawar lantarki aiki ne na na'urorin lantarki waɗanda ke yin ayyukansu a cikin yanayin lantarki ba tare da haifar da tsangwama ba.
Daidaitawar Electromagnetic yana da ma'anoni uku: 1. Kayan lantarki za su kasance masu iya murkushe tsangwama na lantarki na waje.2. Tsangwama na lantarki da kayan aikin da kansa ke samarwa zai kasance ƙasa da ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun kayan aiki na yau da kullum na sauran kayan lantarki a cikin yanayin lantarki guda ɗaya;3. Daidaituwar Electromagnetic na kowace na'urar lantarki abu ne mai aunawa.
Abubuwa uku na hana tsangwama
Akwai abubuwa guda uku da zasu zama tsangwama na lantarki: tushen kutsawa na lantarki, hanyar haɗakarwa ta kutsawar lantarki, kayan aiki masu mahimmanci da kewaye.
1. Maɓuɓɓugan hargitsi na lantarki sun haɗa da tushen rikice-rikice na yanayi da hanyoyin tashin hankali na mutum.
2. Hanyoyin haɗin kai na damuwa na lantarki sun haɗa da gudanarwa da radiation.
(1) Haɗin kai: Abun tsangwama ne cewa ana gudanar da amo kuma an haɗa su daga tushen tashin hankali zuwa na'urori masu mahimmanci da kewaye ta hanyar haɗin kai tsakanin tushen tashin hankali da kayan aiki masu mahimmanci.Da'irar watsawa ta haɗa da masu gudanarwa, sassan kayan aiki, samar da wutar lantarki, impedance gama gari, jirgin ƙasa, resistors, capacitors, inductor da inductor juna, da dai sauransu.
(2) haɗaɗɗiyar radiation: Siginar tashin hankali yana yaduwa ta hanyar matsakaici a cikin nau'in raƙuman wutar lantarki mai haskakawa, kuma makamashin tashin hankali yana fitowa a cikin sararin da ke kewaye bisa ga ka'idar yaduwar lantarki.Akwai nau'ikan haɗin kai guda uku na gama gari: 1. Wutar lantarki da ke fitarwa ta hanyar eriyar tashin hankali ta karɓi eriya ta kayan aiki masu mahimmanci.2.Filin lantarki na sararin samaniya yana haɗe da inductively ta hanyar madugu, wanda ake kira filin haɗin kai zuwa layi.3.Babban mitar shigar da siginar samar da haɗin gwiwa tsakanin masu gudanarwa guda biyu ana kiransa haɗakar layi-zuwa-layi.
4. Maganin hana tsangwama kashi uku
yana bayyana da'ira ta matakin tsangwama da aka bayyana a cikin N, sannan n za a iya amfani da shi don ayyana ma'anar NG * C / I: G a matsayin ƙarfin tushen amo;C shine abin haɗakarwa wanda tushen amo ke watsawa zuwa wurin da ya rikice ta wata hanya;Ni ne aikin hana tsangwama na da'ira mai rikicewa.
G, C, I wato anti-tsangwama abubuwa uku.Ana iya ganin cewa matakin tsangwama a cikin da'irar ya yi daidai da ƙarfin g na tushen amo, daidai da ma'auni mai haɗakarwa C, kuma ya yi daidai da aikin hana tsangwama I na da'irar damuwa.Don ƙara n ƙarami, kuna iya yin haka:
1. G ya zama ƙarami, wato, haƙiƙanin kasancewar ƙarfin tushen tsoma baki a wurin don murkushe ƙarami.
2. C ya kamata ya zama ƙarami, amo a cikin hanyar watsawa don ba da babbar damuwa.
3. Ina ƙarawa, a cikin tsaka-tsakin don ɗaukar matakan hana tsangwama, ta yadda ikon hana tsangwama na kewayawa, ko dakatar da amo a wurin tsangwama.
Tsarin hana tsangwama (EMC) ya kamata ya fara daga abubuwa uku don hana tsangwama kuma ya kai ga ma'auni na EMC, wato, don hana tushen tashin hankali, yanke hanyar haɗa wutar lantarki da inganta rigakafi na kayan aiki masu mahimmanci.
3. Ka'idar neman tushen amo,
komai sarkakkiyar lamarin, ya kamata a fara nazarin hanyar danne hayaniya a madogararsa.Sharadi na farko shine nemo tushen tsoma baki, na biyu shine nazarin yiwuwar murkushe hayaniya da daukar matakan da suka dace.
Wasu hanyoyin tsangwama a bayyane suke, kamar walƙiya, watsa rediyo, grid ɗin wuta akan aiki na kayan aiki masu ƙarfi.Wannan tushen tsoma baki ba zai iya ɗaukar mataki a tushen tsangwamar ba.
Wuraren lantarki sun fi wahalar samun tushen tsangwama.Nemo tushen tsangwama shine: halin yanzu, canjin ƙarfin lantarki shine wurin tushen kutsewar kewayen lantarki.A cikin sharuddan lissafi, manyan wuraren DI / dt Da du / DT sune tushen tsangwama.
4. Ka'idojin gano hanyoyin yada amo
1. Babban tushen hayaniyar haɗakarwa na inductive yawanci shine yanayin babban bambancin halin yanzu ko babban aiki na yanzu.
2. Bambance-bambancen wutar lantarki suna da girma ko babba a cikin yanayin aiki mai ƙarfi, yawanci shine babban tushen haɗin haɗin gwiwa.
3. Hayaniyar haɗin kai na gama gari kuma ana haifar da shi ta hanyar raguwar ƙarfin lantarki a kan rashin daidaituwa na gama gari saboda sauye-sauyen canje-canje a halin yanzu.
4. Don sauye-sauyen canje-canje a halin yanzu, sashin inductance da ya haifar da tasiri yana da matukar tsanani.Idan halin yanzu bai canza ba,.Ko da cikakkiyar ƙimar su tana da girma sosai, ba sa haifar da ƙarar ƙararrawa ko amo mai ƙarfi kuma suna ƙara juzu'in tsayayyen ƙarfin lantarki zuwa ga abin da ya faru na gama gari.
Abubuwa uku na hana tsangwama
