Igumbi le-arc le-miniature circuit breaker XMCBK-63
Isakhiwo segumbi le-arc legridi yensimbi : igumbi le-arc lifakwe inombolo ethile yamapuleti ensimbi (izinto ezisebenza kazibuthe) zogqinsi oluyi-1 ~ 2.5mm.Ingaphezulu legridi lifakwe i-zinc, ithusi noma i-nickel.Indima ye-electroplating ayigcini nje ukuvimbela ukugqwala, kodwa futhi nokwandisa ikhono lokucisha i-arc (i-copper plating eshidini lensimbi i-μm embalwa kuphela, ngeke ithinte ukuqhutshwa kazibuthe kweshidi lensimbi).I-Copper plating kanye ne-zinc plating inomsebenzi ofanayo ekuphuleni kwamandla.Kodwa uma ihlanganiswe ngethusi, ukushisa kwe-arc kuzokwenza i-powder yethusi igijimele ekhanda lokuxhumana, lenze libe yi-alloy yesiliva yethusi, okuzobangela imiphumela emibi.I-Nickel Plating isebenza kahle, kodwa intengo iphezulu.Ngesikhathi sokufakwa, amagridi aphezulu naphansi ayanyakaziswa, futhi ibanga phakathi kwamagridi lithuthukiswa ngokuya ngama-breaker circuit ahlukene kanye namakhono ahlukene okuphuka kwe-short-circuit.
