Igumbi le-Arc le-air circuit breaker XMA8GB
Ngokusekelwe kumgaqo wokucima i-arc, ukukhetha inkqubo yokucima i-arc enengqiqo, oko kukuthi, uyilo lwesakhiwo segumbi lokucima i-arc.
Isakhiwo segridi yentsimbi ye-arc gumbi : igumbi le-arc lixhotyiswe ngenani elithile lamacwecwe ensimbi (izinto eziphathekayo) ze-1 ~ 2.5mm ubukhulu.Umphezulu wegridi i-zinc, ithusi okanye i-nickel efakwe.Indima ye-electroplating ayikona nje ukuthintela umhlwa, kodwa nokwandisa amandla okucima i-arc (i-copper plating kwiphepha lensimbi yi-μm embalwa kuphela, ayiyi kuchaphazela ukuhanjiswa kwamagnetic kweshiti lensimbi).I-Copper plating kunye ne-zinc plating inomsebenzi ofanayo ekuphuleni okwangoku.Kodwa xa ifakwe ngobhedu, ukushisa kwe-arc kuya kwenza umgubo wobhedu uqhubele kwintloko yoqhagamshelwano, uwenze ube yi-alloy yesiliva yobhedu, eya kubangela imiphumo emibi.I-Nickel plating iqhuba kakuhle, kodwa ixabiso liphezulu.Ngethuba lokufakela, iigridi eziphezulu kunye nezisezantsi ziphazamisekile, kwaye umgama phakathi kweegridi uphuculwe ngokweendlela ezahlukeneyo zokuqhawula iisekethe kunye nezakhono ezahlukeneyo zokuqhawula i-short-circuit.
