1. Dalilan corona
Corona ana haifar da ita ne saboda filin lantarki da bai yi daidai ba yana samuwa ta hanyar madugu mara daidaituwa. Lokacin da ƙarfin lantarki ya tashi zuwa wani ƙima a kusa da lantarki tare da ƙaramin radius mai lanƙwasa a kusa da filin lantarki mara daidaituwa, fitarwa zai faru saboda iska mai kyauta, yana samar da korona.Domin filin lantarki da ke gefen korona yana da rauni sosai kuma ba a sami rarrabuwar kawuna ba, abubuwan da aka caje a gefen korona ainihin ions ne na lantarki, kuma waɗannan ions suna haifar da fitar da korona.A taƙaice, korona yana haifar da wutar lantarki lokacin da madubin lantarki mai ƙaramin radius na lanƙwasa ya fita cikin iska.
2. Abubuwan da ke haifar da korona a cikin manyan injina
Filin wutar lantarki na iskar stator na babban injin mai ƙarfin lantarki yana mai da hankali ne a wuraren samun iska, ramukan fita na linzamin kwamfuta, da ƙarewar iska. Lokacin da ƙarfin filin ya kai wani ƙima a wani wuri na gida, iskar gas ɗin yana fuskantar ionization na gida, kuma shuɗi mai haske yana bayyana a wurin ionized. Wannan shine lamarin corona. .
3. Hatsarin corona
Korona yana samar da tasirin thermal da ozone da nitrogen oxides, wanda ke ƙara yawan zafin gida a cikin nada, yana haifar da mannewa ya lalace da carbonize, da insulation na strand da mica su zama fari, wanda hakan ya sa igiyoyin su zama sako-sako, gajere. circuited, da kuma rufi shekaru.
Bugu da ƙari, saboda rashin daidaituwa ko rashin daidaituwa tsakanin ma'aunin zafin jiki na thermosetting da bangon tanki, za a haifar da fitarwa a cikin rata a cikin tanki a ƙarƙashin aikin girgizar lantarki na lantarki.Haushin zafin gida da wannan fitar da tartsatsin ya haifar zai lalata saman rufin.Duk wannan zai haifar da babbar illa ga rufin motar.
