Njira yogwiritsira ntchito kunja imayendetsa kukhudzana kosuntha, komwe kumatsegula ndi kutseka dera lolumikizidwa.Chotsekereza cha vacuum chimakhala ndi dzanja lowongolera kuti lizitha kusuntha komanso kuteteza mavuvu otsekera kuti asagwedezeke, zomwe zingafupikitse moyo wake.
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.
M'mabowo ophulika, zida zolumikizirana ndi vacuum-interrupter zimakhala ndi 50-50 copper-chromium alloy.Zitha kupangidwa powotcherera pepala la aloyi yamkuwa ndi chrome pamwamba ndi pansi pampando wokhala ndi mkuwa wopanda mpweya.Zida zina, monga siliva, tungsten ndi tungsten, zimagwiritsidwa ntchito popanga zosokoneza zina.Kulumikizana kwa chosokoneza cha vacuum kumakhudza kwambiri mphamvu yake yosweka, kulimba kwa magetsi komanso kuchuluka kwa kudula komweko.
Pamene amadula kuchuluka kwa panopa, pa mphindi kulekana kwa zosintha ndi static kukhudzana, panopa amachepa mpaka pamene kulankhula basi kupatukana, chifukwa cha kuwonjezereka kwamphamvu kukana pakati maelekitirodi ndi kuwonjezeka mofulumira kutentha, mpaka. Evaporation ya chitsulo cha elekitirodi imachitika, ndipo nthawi yomweyo, mphamvu yayikulu kwambiri yamagetsi imapangidwa, zomwe zimapangitsa kuti pakhale umuna wamphamvu kwambiri komanso kuwonongeka kwa mipata, zomwe zimapangitsa kuti vacuum arc.Pamene mphamvu yafupipafupi yamagetsi ili pafupi ndi ziro, ndipo nthawi yomweyo, chifukwa cha kuwonjezeka kwa mtunda wotsegula, Madzi a m'magazi a vacuum arc amafalikira mofulumira.Arc ikadutsa zero, sing'anga yomwe ili mumpata wolumikizana imasintha kuchokera kokondakita kupita ku insulator, kotero kuti yapano imadulidwa.Chifukwa cha mawonekedwe apadera a kukhudzana, kusiyana kukhudzana kumatulutsa longitudinal magnetic field pa arcing.Mphamvu ya maginitoyi imatha kupangitsa kuti arc igawidwe mozungulira pamalo olumikizirana, kukhalabe ndi magetsi otsika arc, ndikupanga chipinda chozimira cha vacuum arc kukhala ndi liwiro lalitali la post arc dielectric mphamvu, zomwe zimapangitsa mphamvu yaying'ono ya arc ndi kuwononga pang'ono.
