RDV6-12 seriesHigh voltage AC Vacuum Circuit Breaker ine 3-phase A C12kV indoor switch device inowanzoiswa paMiddle type cabinet KY28 series, Box type substation uye Armored type cabinet, semudziviriri weindasitiri, michina yemagetsi yemugodhi uye kugadzira nekupwanya circuit kubva ku load current, overload current uye short-circuit protect current. Uye Nekuda kwekushandisa Vacuum breaker, chigadzirwa ichi chakakodzera nzvimbo inoshanda pasi pe rated operation current, kana kuvhura nekupwanya short-circuit kakawanda.
1. Maitiro akavimbiswa mashandiro
2.Small volume, hombe kugona
3. Kukwanisa kupinza waya kwakasimba kwazvo
4.Kudzivirira kwakanaka pakati pezvikamu
5. Kufambisa kwakasimba kwazvo
6.Kukwira kwekupisa kwakaderera uye kushandiswa kwesimba
Tsananguro yeMuenzaniso
Zvakatipoteredza
a) Tembiricha: Max +40C, Min -10C (30C, nzvimbo yekuchengetera nekutakura)
b) Kureba: Kureba kupfuura 2000m. Chinodiwa chakakosha chinofanira kubvunzana nesu.
c) Hunyoro hwezuva nezuva: avhareji yezuva nezuva haifanire kupfuura 95%, avhareji yemwedzi pamwedzi haifanire kupfuura 90%. Uye avhareji yemhepo yakaguta pazuva haifanire kupfuura 2.2kPa, avhareji yemwedzi isingafanire kupfuura 1.8kPa. Uye kana mvura yanyanya kunyorova, inotonhora,
kunyorovesa kunogamuchirwa.
d) Kudengenyeka kwenyika: kwete kupfuura 8 nhanho
e) Nzvimbo yekuisa: pasina moto, kuputika, guruva, ngura yemakemikari, zviri pachena

1. Kamuri rekudzima reVacuum arc rinoshandisa zvinhu zvekubata zveCu Cr, uye chimiro chekubata chakaita sekapu chesimba remagineti renguva refu rine mwero mudiki wekusakara, Simba re dielectric rakagadzikana rinopora nekukurumidza mushure mekudzima kwearc, nhanho shoma yekuvhara, simba rakasimba rekugadzira nekupwanya, hupenyu hwemagetsi hurefu.
2. Pakati pedanda rekudzivirira kupisa negoko receramic rekamuri rekudzimisa rakagadzirwa nesimbi. Uchishandisa rabha resilicon rabha rinoyerera, wedzera kushanda kwekudzivirira kupisa. Chiketi cheambrellas chine daro rakakura rekukwira pamusoro pembiru yedanda, kuti chiwedzere simba remagetsi rinotsungirira kupisa uye simba remagetsi rinopindira kupisa, chinogona kusangana nezvinodiwa zvehunyanzvi munzvimbo yakakwirira.
3. Nzira yekushandisa ndiyo nzira yekuchengetedza simba reSpring yekuronga ndege, ine mabasa ekuchengetedza nemaoko uye ekuchengetedza mota, kuvandudza kugadzikana kwekushanda.
4. Iyi nzira inoshanda necircuit breaker, yakagamuchirwawo nePermanent magnetic actuatormechanism, nzira iyi inoderedza 60% yezvinhu zvichienzaniswa nechitubu chenguva dzose, inoderedza kutadza nekuda kwezvikamu.
