Isishwankathelo

I-ZW8-12 yangaphandle i-high-voltage vacuum breaker circuit breaker, isigaba sesithathu se-AC 50Hz yangaphandle i-high-voltage switchgear.Idityaniswe ngokusebenza, isekethe yokuqhubela phambili, inkqubo yokugquma, itywina kunye negobolondo, kwaye ulwakhiwo lulonke luhlobo lwebhokisi eqhelekileyo yesigaba esithathu.Isetyenziselwa igridi yamandla yasemaphandleni eyi-10kV kunye nenkqubo yamandla egridi yamandla asezidolophini, njengokwahlulahlula, umbane odibeneyo wangoku, umsinga ogqithisayo, umsinga omfutshane kunye nezinye iindawo ezifanayo.
Ukuphumeza umgangatho we-GB1984-2003 "High Voltage AC Circuit Breaker" GB/T11022-1999 "IiMfuno eziQhelekileyo zobuGcisa kwi-High Voltage Switchgear kunye neMigangatho yeZixhobo zoLawulo" IEC62271-100 "I-High Voltage AC Circuit Breaker"

Imiqathango yokusetyenziswa eqhelekileyo

◆ Ubushushu be-Ambient: -40℃~+40℃;
◆ Ukuphakama: ≤3000m (ukuba ukuphakama kunyuka, inqanaba lokulinganisa elilinganisiweyo liya kunyuka ngokufanelekileyo);
◆ Umoya ojikelezileyo unokungcoliswa luthuli, umsi, igesi edliwayo, umphunga okanye isitshizi setyuwa, kwaye inqanaba longcoliseko ngu-IV;
◆Isantya somoya asidluli kwi-34m/s (ilingana ne-700Pa kumphezulu wecylindrical);
◆Ukungcangcazela okanye intshukumo yomhlaba evela ngaphandle kwesixhobo sokutshintsha kunye nesixhobo sokulawula sinokungahoywa;
◆Iimeko ezikhethekileyo zokusebenzisa.(Ukuba ufuna ukuyifaka phantsi kweemeko eziqhelekileyo zokusetyenziswa ezahlukileyo kwezi zingasentla, nceda uxoxe nathi).
