I-Wholesale 40.5KV HW-12 yangaphandle yamandla aphezulu aphezulu I-AC vacuum circuit breaker VCB circuit breaker yueqing

1. Ikhabhinethi yamanje yokushintsha engu-4000A idinga ukuqinisa ukupholisa komoya
2 Uma isilinganiso sokunqamuka kwesekethe esifushane singaphansi kuka-40KA, Q = 0.3s; lapho isilinganiso sokuphulwa kwesekethe esifushane sikhulu noma silingana no-40KA, Q = 180s

Isifinyezo

I-hW-12 yangaphandle ene-voltage ephezulu ye-AC vacuum circuit breaker iyisisetshenziswa samanje sangaphandle sokusabalalisa esisebenzayo esinogesi olinganiselwe ongu-40.5k no-50H wezigaba ezintathu ze-AC. Isetshenziselwa kakhulu ukunqanyulwa kwenethiwekhi yokusabalalisa kanye nokuvala shaqa. layisha okwamanje, layisha kakhulu amandla amanje kanye nesifunda esifushane ohlelweni lwamandla. ilungele ukuvikelwa nokulawula ezinhlelweni zokusabalalisa amandla eziteshini ezincane kanye namabhizinisi ezimboni nezimayini. ilungele amagridi kagesi asemaphandleni kanye nezindawo ezisetshenziswa njalo. Ifanelekakhulu izidingo zenethiwekhi yasemadolobheni kanye nenethiwekhi yasemaphandleni
