Yakayerwa kugona kwekuputsa kwemhepo pfupi kwenguva refu muICU

Kune mhando mbiri dzezviratidzo zvekukwanisa kuputsa simba remacircuit breakers: rated ultimate short-circuit breaking capacity ICU uye rated operating short-circuit breaking capacity ICS. Sechiratidzo chinoratidza, ICS haingofungi nezve breaking capacity yekutyoka kwedunhur, asi sechiratidzo chekutyora, ndiko kuti, mushure mekutyora zvikanganiso zvakawanda zve-short-circuit, inogona kuramba ichivimbisa kushanda kwayo kwakajairika.macircuit breakers ekesi akaumbwa, panofanira kunge paine ICU yakakwana yekupwanya current yepfupi uye kupwanya switch. Zvinoenderana nemutemo, maIcs ekesi rakaumbwamuputsi wedunhuinokodzera chero bedzi iri pamusoro pe25%Icu. Parizvino, maIcs mazhinji emacircuit breakers ari pamusika ari pakati pe (50%-75%) Icu, saka kune masisitimu ekuparadzira magetsi asingade magetsi akawanda, Icu chete ndiyo inofanira kufungwa nezvayo.
