ZW20-12 Outdoor High Voltage Vacuum Circuit Breaker

Mwachidule

ZW20-12 panja mkulu-voltage vacuum circuit breaker ndi panja high-voltage switchgear yokhala ndi voliyumu ya 12KV ndi magawo atatu a AC 50Hz.Amagwiritsidwa ntchito kwambiri kuti asalumikizane ndi kutseka katundu wapano, kuchulukirachulukira pano komanso kwakanthawi kochepa kwamagetsi amagetsi.Ndi oyenera kuteteza ndi kulamulira substations, mafakitale ndi mabizinezi migodi, ndi maukonde m'tauni ndi kumidzi kugawa, makamaka malo ndi ntchito pafupipafupi ndi zodziwikiratu kugawa maukonde maukonde ankalamulira.Chogulitsachi chikufanana ndi chowongolera kuti chikwaniritse zofunikira za makina opangira makina ogawa ndikumaliza ntchito yobwereza yachikhalidwe modalirika komanso moyenera.Mapangidwe osindikizira okhwima amtundu wa bokosi amatengedwa, ndipo mkati mwake mumadzazidwa ndi mpweya wa SF6.Ili ndi ntchito yabwino yosindikiza ndipo siyimakhudzidwa ndi dziko lakunja.Izi ndi zopanda kukonza.Makina ogwiritsira ntchito masika amatengera makina oyendetsa ma chain chain main drive ndi ma multi-stage tripping system, odalirika kwambiri.

Mawonekedwe

◆ Imatengera zozimitsa za vacuum arc ndi SF6 kutchinjiriza gasi, zomwe zimakhala ndi ntchito yabwino yosweka;
◆ Mafuta opanda mafuta, osindikizidwa bwino, bokosi lachidziwitso, kuphulika, chinyezi, ndi condensation-proof proof design design, yokhala ndi nthawi yayitali yosamalira;
◆ Miniaturized electric spring operating mechanism imapangitsa kuti ikhale yochepa mphamvu yogwiritsira ntchito, yodalirika kwambiri komanso kulemera kwake;
◆ Kapangidwe kamangidwe kameneka ndi koyenera, ntchito yamagetsi ndi yamanja imasinthasintha, ndipo mpando kapena kupachika kopachika kungasankhidwe mosavuta;
◆ Pothandizira ma terminals anzeru odyetsa, ntchito yakutali imatha kuzindikirika kuti ikwaniritse zosowa za makina ogawa;

Mikhalidwe Yachilengedwe

1. Kutentha kwa mpweya wozungulira: malire apamwamba 60 °C, malire otsika -30 °C;
2. Kutalika: ≤ 3000m (ngati kutalika kumawonjezeka, mlingo wotsekemera wotsekemera udzawonjezeka moyenerera);
3. Matalikidwe: Kuchuluka kwa seismic sikudutsa madigiri 8;
4. Kutentha kwapakati pa tsiku ndi tsiku kwa mpweya sikuposa 95%, ndipo pafupifupi mwezi uliwonse siposa 90%;
5. Palibe moto, ngozi ya kuphulika, kuipitsidwa kwakukulu, dzimbiri la mankhwala ndi kugwedezeka kwamphamvu.
