panja vacuum circuit breaker mfundo

Mu dera, wodutsa dera amagwira ntchito ngati fuseji, koma fuseyi imatha kugwira ntchito kamodzi kokha, pamene oyendetsa dera angagwiritsidwe ntchito mobwerezabwereza.Malingana ngati zamakono zikufika pamtunda woopsa, zimatha kuyambitsa dera lotseguka.waya wamoyo mu dera lolumikizidwa ndi malekezero onse a switch.Pamene lophimba aikidwa pa boma, panopa umayenda kuchokera terminal pansi, sequentially kudzera maginito maginito, kusuntha contactor, malo amodzi contactor, ndipo potsiriza kuchokera pamwamba terminal.

Masiku ano akhoza magnetize electromagnet.Mphamvu ya maginito yopangidwa ndi electromagnet imawonjezeka ndi kuwonjezeka kwamakono.Ngati panopa achepa, mphamvu ya maginito idzachepanso.Pomwepo ikalumpha kumalo owopsa, maginito amagetsi amapanga mphamvu yamaginito yayikulu yokwanira kukoka ndodo yachitsulo yolumikizidwa ndi kulumikizana kosinthira.Izi tilts kusuntha contactor kutali contactor malo amodzi, amenenso amadula dera.Pakalipano wasokonezedwa.

Zowononga zakunja za vacuum zitha kugwiritsidwa ntchito kugawa mphamvu zamagetsi, kuyambitsa ma asynchronous motors pafupipafupi, ndikuteteza zingwe zamagetsi ndi ma mota.Akakhala ndi zochulukira kwambiri kapena zocheperako komanso zolakwika za undervoltage, amatha kudula gawolo.Ntchito yawo ndi yofanana ndi kusintha kwa fuse.Kuphatikiza ndi kutenthedwa wopatsirana etc. Ndipo pambuyo kuswa cholakwika panopa, sipafunika kusintha mbali.
