Momwe mungawerengere kuchuluka kwa chingwe?-Wokhazikika

Mphamvu yaposachedwa ya kondakitala kapena chingwe ndi mphamvu yayikulu yomwe imatha kunyamula mosapitilira kutentha kwake.Amadziwikanso kuti ampacity.

Pamene zingwe zikugwira ntchito zimawonongeka ndi magetsi zomwe zimawoneka ngati kutentha mu kondakitala, zotsekemera ndi zina zilizonse zachitsulo pomanga.Chiwerengero chamakono chidzadalira momwe kutentha uku kumatayikira kudzera pamwamba pa chingwe ndi kumadera ozungulira.Kutentha kwa kutentha kwa chingwe ndizomwe zimatsimikizira mphamvu zomwe zilipo panopa za chingwe.Kutentha kwakukulu kwa kutentha kwa chingwe kumatsimikiziridwa ndi zinthu zotsekemera.

Posankha kutentha kozungulira ngati maziko a malo ozungulira, kukwera kovomerezeka kwa kutentha kumapezeka komwe kuwerengetsera kwa chingwe kungathe kuwerengedwa ku malo enaake.Ngati mtengo wotsutsana ndi kutentha kwa zinthu zosanjikiza muzitsulo zimadziwika, zomwe zilipo panopa zingathe kuwerengedwa.

Njira yowerengera kuchuluka kwa kunyamula kwapano ndi:

I = zovomerezeka panopa

∆Φ = Kukwera kwa kutentha kwa Kondakitala (K)

R= Kukaniza kwapano pamlingo wautali wa kondakitala pakutentha kwambiri (Ω/m)

Wd = kutayika kwa dielectric pa kutalika kwa unit kwa kutsekereza kozungulira kokondakitala (W/m)

T1 = Kukana kwamafuta pautali wa unit pakati pa kondakitala imodzi ndi sheath (K m/W)

T2 = kukana kwamafuta pa kutalika kwa chofunda pakati pa sheath ndi zida (K m/W)

T3 = kukana kwamafuta pautali wagawo la Sheath yakunja ya chingwe (K m/W)

T4 = kukana kwamafuta pautali wagawo pakati pa chingwe pamwamba ndi sing'anga yozungulira (K m/W)

n = chiwerengero cha ma conductor onyamula katundu mu chingwe (makonda a kukula kofanana ndi kunyamula katundu womwewo)

λ1 = Chiŵerengero cha zotayika mu sheath yachitsulo kuti ziwonongeke zonse muzitsulo zonse mu chingwecho

λ2 = chiŵerengero cha kutayika kwa zida zankhondo mpaka kutayika kwathunthu kwa ma conductor onse mu chingwecho.
