Yadda za a lissafta ƙimar kebul na yanzu?-Slocable

Ƙarfin ɗauka na yanzu na madugu ko kebul shine matsakaicin halin yanzu wanda zai iya ci gaba da ɗauka ba tare da wuce ƙimar zafin sa ba.An kuma san shi da rashin ƙarfi.

Yayin da igiyoyin ke aiki suna fama da hasarar wutar lantarki wanda ke bayyana kamar zafi a cikin madugu, insulation da duk wasu abubuwan ƙarfe a cikin ginin.Ƙididdigar halin yanzu zai dogara ne akan yadda wannan zafi ya ɓace ta hanyar kebul na USB da kuma cikin yankunan da ke kewaye.Ma'aunin zafin jiki na kebul shine ƙayyadaddun abu a cikin ƙarfin ɗaukar kebul na yanzu.Matsakaicin ma'aunin zafin jiki na kebul an ƙaddara shi da gaske ta hanyar abin rufewa.

Tsarin ƙididdiga ƙarfin ɗaukar nauyi na yanzu shine:

I = halattaccen ƙimar halin yanzu

∆Φ = Hawan zafin jiki a cikin (K)

R= Madadin juriya na yanzu kowane tsayin raka'a na jagora a matsakaicin zafin aiki (Ω/m)

Wd = asarar dielectric kowane tsayin raka'a don rufin da ke kewaye da madubi (W/m)

T1 = Juriya na thermal kowane tsayin raka'a tsakanin jagora ɗaya da kube (K m/W)

T2 = juriya na thermal kowane tsawon raka'a na gado tsakanin kube da sulke (K m/W)

T3 = juriya na thermal kowane tsawon raka'a na waje Sheath na kebul (K m/W)

T4 = juriya na thermal kowane tsawon raka'a tsakanin saman kebul da matsakaicin kewaye (K m/W)

n = adadin masu ɗaukar kaya a cikin kebul (masu gudanarwa masu girman daidai da ɗaukar kaya iri ɗaya)

λ1 = Matsakaicin asarar da ke cikin kube na ƙarfe zuwa jimlar asara a cikin duk masu gudanar da kebul ɗin

λ2 = rabon asarar da aka yi a cikin sulke zuwa jimillar asara a cikin duk masu gudanar da kebul ɗin.
