Kapangidwe ka zophulitsira ma vacuum circuit

Chotsekereza magetsi cha vacuum ndi chosinthira magetsi chomwe chimagwiritsidwa ntchito kuwongolera, kuteteza ndi kulekanitsa ma circuit amagetsi. Mosiyana ndi ma circuit breaker achikhalidwe omwe amadalira mafuta kapena gasi ngati chozimitsira magetsi, ma circuit breaker a vacuum amagwiritsa ntchito chipinda chozimitsira magetsi cha vacuum arc ngati njira yozimitsira magetsi omwe amapangidwa panthawi yophwanya magetsi. Chimodzi mwazabwino zazikulu za chotsekereza magetsi cha vacuum ndi kuthekera kwake kutsegula magetsi mwachangu, kuchepetsa kuwonongeka ndikuletsa ngozi zamagetsi.

Kapangidwe ka chotseka dera la vacuum nthawi zambiri kamakhala ndi zigawo zitatu zazikulu: chipinda chozimitsira arc, njira yogwirira ntchito ndi chinthu chowongolera. Chosokoneza chimakhala ndi zolumikizira ziwiri zachitsulo zolekanitsidwa mkati mwa chipinda chotseka. Chotseka dera chikatsegulidwa, chotseka dera lamagetsi champhamvu kwambiri chimatsimikizira kutetezedwa pakati pa zolumikizira. Komabe, pakachitika vuto ndipo chotseka dera chikufunika kugwedezeka, zolumikizirazo zimasonkhana, kuyambitsa njira yozimitsira arc.

Makina ogwiritsira ntchito ali ndi udindo wotsegula ndi kutseka chotseka ma circuit breaker pansi pa mikhalidwe yabwinobwino komanso yolakwika. Makinawa amagwiritsa ntchito ukadaulo wosiyanasiyana monga mphamvu yosungidwa (ma spring) kapena ma electromagnetic actuator kuti apange mphamvu yofunikira yamakina. Kumbali inayi, zinthu zowongolera zimaonetsetsa kuti njira zogwirira ntchito zikugwirizana bwino. Zimaphatikizapo ma switch othandizira, ma relay ndi ma timer ndipo zimagwira ntchito monga kuyambitsa ma trip coil, kuzindikira zolakwika ndi kuchotsa zolakwika. Njira zolumikiziranazi zimatsimikizira kuti chotseka ma circuit breaker chikugwira ntchito bwino komanso motetezeka.

Mwachidule, zotsekera magetsi zamagetsi ndi gawo lofunika kwambiri pamakina amagetsi, kuonetsetsa kuti zida ndi antchito akutetezedwa ku zolakwika zamagetsi. Kapangidwe ka chotsekera magetsi zamagetsi chimakhala ndi chipinda chozimitsira magetsi, njira yogwirira ntchito komanso chinthu chowongolera, chomwe chimagwirizana kuti chikwaniritse bwino kusweka kwa magetsi ndi kuzimitsa magetsi. Kumvetsetsa zigawo zake ndi ntchito zake kumathandiza mainjiniya ndi akatswiri kupanga zisankho zodziwa bwino popanga, kukhazikitsa, ndikusunga magetsi m'nyumba, m'mabizinesi, komanso m'mafakitale. Pogwiritsa ntchito zabwino zambiri za zotsekera zamagetsi zamagetsi zamagetsi, titha kutsimikizira kuti pali magetsi otetezeka komanso odalirika padziko lonse lapansi.
