Amaphuzu avelele e-MCCB
Idizayini yesakhiwo enengqondo yabathintwayo abahambayo nabagxilile yenza inani eliphakeme lesekethe emfushane namandla alolu chungechunge lwemikhiqizo libe lincane kakhulu kunokulindelekile.
Umgomo wokusebenza: i-current ingena isuka kothintana naye ogxilile
1, iphuma koxhumana naye ogxilile
2, ngokusebenzisa othintana naye ohambayo, ongaguquki wesiliva kanye nothintana naye onyakazayo. Othintana naye onyakazayo unqamula ngokushesha ngaphansi kwesenzo samandla kagesi anamandla wokudonsa (i-Holm force kanye ne-Lorentz force) ukuze kuthuthukiswe isivinini sokuphuka.
Idizayini yokuphefumula komoya: lapho isifunda esikhulu esifushane senzeke kumjikelezo, izingxenye ezikhiqiza igesi zizokhiqiza enye igesi ngaphansi kokushisa okuphezulu kwe-arc, ukucindezela komoya ebhokisini leyunithi yokuxhumana kukhula ngokushesha, futhi ukugeleza komoya okunesivinini esikhulu kungakhiwa ngokuphuma komoya kwegumbi lokucima i-arc, elingacisha ngokuphumelelayo i-arc.
