Cholumikizira cholumikizira nthawi zambiri chimakhala ndi cholumikizira chimodzi chokhazikika komanso chosuntha, mvuto wopindika wolola kusunthako, ndi zishango za arc zotsekeredwa mugalasi losindikizidwa bwino, nyumba ya ceramic kapena chitsulo yokhala ndi vacuum yayikulu.Kulumikizana kosuntha kumalumikizidwa ndi chingwe chosinthika kupita kudera lakunja, ndipo chimasunthidwa ndi makina pomwe chipangizocho chikufunika kutsegula kapena kutseka.Popeza kuthamanga kwa mpweya kumakonda kutseka zolumikizirana, makina ogwiritsira ntchito ayenera kutsegulira zolumikizirana ndi mphamvu yotseka yamphamvu ya mpweya pamivuto.
Mpanda wa chosokonezacho umapangidwa ndi galasi kapena ceramic.Zisindikizo za Hermetic zimatsimikizira kuti chosokoneza chosokoneza chimasungidwa kwa moyo wa chipangizocho.Malo otsekerapo sayenera kulowa mpweya, ndipo musatuluke mpweya wotsekeka.Mvulo zachitsulo zosapanga dzimbiri zimalekanitsa vacuum yomwe ili mkati mwa chosokoneza kuchokera kumlengalenga wakunja ndikusuntha cholumikiziracho mkati mwamtundu wina, ndikutsegula ndi kutseka chosinthira.
Ngakhale zida zina zotsekera zotsekera zimakhala ndi zolumikizana ndi matako osavuta, zolumikizira nthawi zambiri zimapangidwa ndi mipata, zitunda, kapena ma grooves kuti athe kuswa mafunde akulu.Arc yaposachedwa yomwe imadutsa pazolumikizana zowoneka bwino imatulutsa mphamvu zamaginito pagawo la arc, zomwe zimapangitsa kuti malo olumikizana ndi arc asunthike mwachangu pamwamba pa kukhudzana.Izi zimachepetsa kuvala kwa kukhudzana chifukwa cha kukokoloka kwa arc, komwe kumasungunula chitsulo cholumikizana pamalo okhudzana.
Kachulukidwe wa nthunzi zimadalira panopa mu arcing.Chifukwa cha kuchepa kwa mafunde apano kutsika kwawo kwa nthunzi kugwa komanso pambuyo pa ziro zomwe zilipo, sing'angayo imapezanso mphamvu yake ya dielectric yomwe imapatsa kachulukidwe ka nthunzi kuzungulira zolumikizanazo.Chifukwa chake, arc sibwereranso chifukwa mpweya wachitsulo umachotsedwa mwachangu pamalo olumikizirana.

Khalani tcheru:

(1) Njira zopewera kuphulika.
(2) Yang'anirani mosamalitsa kutseka ndi kutsegulira kwa liwiro la vacuum circuit breaker.
(3) Yendetsani mosamalitsa ulendo wolumikizana.
(4) Yang'anirani mwamphamvu katundu wapano.
(5) Kukonzekera kozungulira kwa vacuum circuit breaker.
