Pfupiso
Zvigadzirwa zvedu zvitsva, maNVS1-24 series indoor-voltage vacuum circuit breakers anoshandiswa kuma switchgears mu 24kV power system, seyuniti yekudzora nekudzivirira michina yemagetsi mumaindasitiri nemakambani emigodhi, mapower plants nema substations. Nekuda kwezvakanaka zve vacuum circuit breaker, inonyanya kukodzera kushanda nguva nenguva kunoda rated working current, kana nzvimbo uko short-circuit current inotyoka kakawanda. Circuit breaker inoshandisa dhizaini yakabatana ye operating mechanism uye circuit breaker body. Izvi zviviri chimiro chemberi neshure, chine interlocking function yakavimbika. Circuit breaker inogona kushandiswa seyuniti yekuisa yakagadziriswa. Inogona zvakare kugadzirirwa ne chassis truck muyuniti yengoro yemaoko.
Mitemo yezvigadzirwa
GB/T1984-2014 AC Circuit Breaker ine voltage yakakwira
JB/T3855-2008 3.6-40.5kV AC yemukati ine voltage yakakura yekubvisa circuit breaker
DL/T403-2000 12kV-40.5kV high voltage vacuum circuit breaker inoraira mamiriro ehunyanzvi
IEC62271-100:2008 High Voltage Switchgiya uye Controlgiya Chikamu 100: AC Circuit-breakers
Mamiriro Ezvakatipoteredza
Tembiricha yemhepo: -15 C ~+40C
O Hunyoro hwemhepo: Hunyoro hwezuva nezuva
Avhareji yemhepo inopfungaira pazuva
Kureba ≤ 1000m;
Kuwanda kwekudengenyeka kwenyika
O Nzvimbo yekuisa: Nzvimbo yacho haifanirwe kunge isina mvura, njodzi yekuputika, kusvibiswa kwakakomba, ngura yemakemikari uye kuzununguka kwakanaka.
