Vacuum interrupter ndi chipangizo chamagetsi cha vacuum chomwe chimagwiritsa ntchito vacuum yayikulu yotchinga zozimitsa moto ndikuzindikira ntchito yozimitsa magetsi ndi zolumikizira zomata zosindikizidwa mu vacuum.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.Mwanjira iyi, kusokoneza komwe kulipo komanso moyo wautumiki wa chosokoneza cha vacuum umatheka.
Nthawi zina, chopukutira chotchinga chikhoza kukakamiza kuti mayendedwe apakatikati akhale ziro ziro zisanachitike (ndikusinthanso kwapano) mumayendedwe apano.Ngati nthawi yosokoneza ntchito siyikuyenda bwino ndi mawonekedwe a AC-voltage waveform (pamene arc yazimitsidwa koma ma arc akuyendabe ndipo ionization sinathebe mu chosokoneza), voliyumu imatha kupitilira mphamvu ya gap.Izi zitha kuyatsanso arc, ndikupangitsa mafunde osakhalitsa.Mulimonsemo, oscillation imalowetsedwa mu dongosolo lomwe lingapangitse kuwonjezereka kwakukulu.
Masiku ano, ndi kutsika kochepa kwambiri kwaposachedwa, zotchingira zounikira sizingapangitse kuchuluka kwamagetsi komwe kungachepetse kutchinjiriza kwa zida zozungulira.
