Inkcazo yoMzekelo
Okusingqongileyo
a) Ubushushu: Ubuninzi +40C, Ubuncinane -10C (30C, indawo yokugcina kunye nokuthuthwa)
b) Ukuphakama: Ubuninzi be-2000m. Imfuneko ekhethekileyo kufuneka iqhagamshelane nathi.
c) Ukufuma okunxulumeneyo: umyinge wosuku awuzukudlula kwi-95%, umyinge wenyanga awuzukudlula kwi-90%. Kwaye umyinge woxinzelelo lomphunga ogcweleyo wosuku awuzukudlula kwi-2.2kPa, umyinge wenyanga awuzukudlula kwi-1.8kPa. Kwaye kumhla wokufuma okuphezulu, kuya kubanda,
ukufuma kuyamkeleka.
d) Inqanaba lenyikima: kungabi ngaphezulu kwenqanaba lesi-8
e) Indawo yokufaka: ngaphandle komlilo, ukuqhuma, uthuli, ukubola kweekhemikhali, ngokucacileyo
Umsebenzi osisiseko kunye neempawu
1. Igumbi lokucima i-arc yeVacuum lisebenzisa izinto zoqhagamshelwano zeCu Cr, kunye nesakhiwo soqhagamshelwano esimile okweNdebe sentsimi yemagnethi ende enesantya esincinci sokuguguleka, Amandla e-dielectric azinzileyo alulama ngokukhawuleza emva kokucima i-arc, inqanaba eliphantsi lokuvala, amandla okwakha nokuphuka aqinileyo, ubomi obude bombane.
2.Phakathi kwepali yokuthintela ubushushu kunye neqokobhe le-ceramic legumbi lokucima i-vacuum arc.Usebenzisa i-fluid silicon rubber buffer, yonyusa ukusebenza kokumelana nempembelelo, I-ambrellaskirt enomgama omkhulu wokunyuka phezu komphezulu wepillar yepali, ukuphucula i-powerfrequency ukumelana ne-voltage kunye ne-lightning impulse ukumelana ne-voltage, inokuhlangabezana neemfuno zobugcisa eziphambili kwindawo ephakamileyo.
3. Indlela yokusebenza yindlela yokugcina amandla yaseNtwasahlobo yolungiselelo lwendiza, inemisebenzi yokugcina ngesandla kunye neyokugcina iimoto, ukuphucula uzinzo lokusebenza.
4. Le ndlela yokusebenza ye-circuit breaker, nayo yamkelwe njenge-Permanent magnetic actuatormechanism, le ndlela isebenza ngokunciphisa ii-compounds ezingama-60% xa kuthelekiswa nentwasahlobo eqhelekileyo, inciphisa izinga lempazamo ngenxa yee-compounds.
