Cias nco ntsoov lub peev xwm nqa tam sim no ntawm txhua lub voj voos busbar: daim duab plaub-bar tam sim no-nqa peev: tooj liab npav tam sim no-nqa peev ntawm 40 ° C=kab dav * thickness yam, Tin Bronze kab dav (mm); thickness factor: 20.5 thaum lub busbar yog 12 tuab; Thaum nws yog 10 tuab, nws yog 18.5; Qhov kev txiav txim yog: [12-20.5, 10-18.5, 8-16.5, Tin Bronze 6-14.5, 5-13.5, 4-12.5], [Ceeb Toom]: Raws li cov lus pom zoo ntawm lyq13703983100 thiab kev suav ntxiv, Tin Bronze thawj thickness Cov coefficients 20, 18, 16, 14, thiab 12 yog feem ntau ntxiv 0.5, Tin Bronze uas yog ze dua.
Ob-txheej tooj liab busbar [40 ℃]=1.56-1.58 Ib txheej tooj liab busbar [40 ° C] (nyob ntawm qhov loj ntawm ntu ntu), Tin Bronze 3-txheej tooj liab busbar [40 ° C]=2 ib leeg- txheej tooj liab busbar [40 ° C], Tin Bronze 4-txheej tooj liab busbar [40 ℃]=Ib txheej tooj liab busbar [40 ° C] * 2.45 (qhov kev xaiv no tsis pom zoo, Tin Bronze nws yog qhov zoo dua los siv tshwj xeeb -shaped busbar hloov), tooj liab busbar [40 ° C]=tooj liab busbar [25 ° C] * 0.85, aluminium busbar [40 ℃]=tooj liab bar [40 ℃] / 1.3
Piv txwv li, Tin Bronze lub peev xwm nqa tam sim no ntawm TMY100 * 10 yog: ib txheej: 100 * 18.5=1850 (A) [kos phau ntawv rau 1860A]; ob txheej txheej: 2 (TMY100 * 10) nqa peev: 1850 * 1.58=2923 (A); [Saib phau ntawv qhia rau 2942A]; Tin Bronze Peb txheej: 3 (TMY100 * 10) nqa peev xwm: 1850 * 2=3700 (A) [Saib phau ntawv rau 3780A]
Tag nrho cov kev suav sau saum toj no yog qhov tseeb txaus kom ze rau cov ntaub ntawv phau ntawv.
