I-UPR3 yochungechunge oluthe nkqo lwe-fuse switch lunokusebenza kunye nomthwalo, phezulu nangaphantsi kwi-wire ezayo kunye nocingo oluphumayo lukulungele ukutshintshiselwa. ngelixa i-fuse ifakwe kwi-handle kwaye ingasetyenziselwa njenge-blade yoqhagamshelwano ngokuthe ngqo.
Ibakala langoku yi-250A-630A, i-in-line fuse type isolation switch idityaniswe ne-transformer eqalayo yangoku, inokuxhonywa kwimonitha yefuse.
Imveliso ayinakuqhekeka kuphela ngesigaba esinye, kodwa inokuqhekeka ngezigaba ezintathu ngokuhambelanayo, ukongeza,
Inokugcina indawo enkulu xa imveliso epheleleyo ifakelwa yona, ngoko ke isetyenziswa kakhulu ukungenisa isitishi sohlobo lwebhokisi yokutshintsha i-substation.
Ngokungena kwe-knife-edge kunye nezixhobo zokucima i-arc, kukhuselekile ukusebenza.
Iblade yemela eyohlulayo, ukhuselo olugcweleyo kunye nokhuseleko lwe-semiconductor core fusible lukhetho.
Amandla okusebenza ngomthwalo afikelela kwi-l.3 amaxesha angoku alinganisiweyo.
