40.5kV Kunze Vacuum Circuit Breaker
Chigadzirwa Overview Uye Kushandisa
ZW7A-40.5: CT yakavakirwa-mukati kana kunze, uye kunze kwekunze ndiko kutaridzika kwemuviri kwesilicone rubber kana porcelain.
Chigadzirwa Model Uye Zvinoreva
Mamiriro Ekushanda
Mamiriro ekushandisa akajairika
a.Ambient tembiricha yemhepo, shoma -30 °, yakakura +40 °;avhareji tembiricha kuyerwa mukati maawa makumi maviri nemana haapfuuri 35 °;
b.Kukwirira hakupfuuri 1000m;
c.Chiyero chekusvibiswa kwemhepo yakapoteredza haifaniri kudarika chikamu II;
d.Mhepo yakapoteredza haisi pachena yakasvibiswa neguruva, utsi, gasi rinopisa kana rinopisa, steam kana munyu spray;
e.Ukobvu hwe icing haifaniri kudarika 20mm;
f.Kumhanya kwemhepo hakusi kupfuura 34m/s;
g.Iyo seismic fissure haipfuuri madhigirii masere;
h.Humidity mamiriro:
Avhareji kukosha kwehunyoro hunyoro hwakayerwa mukati me24h, isingapfuuri 95%;
Avhareji kukosha kwehutsi hwemvura yakayerwa mukati me24h haipfuuri 2.2kPa;
Avhareji pamwedzi hunyoro hunyoro haupfuuri 90%;
Avhareji yemwedzi wega wega mhute yemvura haipfuure 1.8kPa;
Kana izvo zvataurwa pamusoro apa zvakajairwa kushandiswa zvakapfuura, ndapota bvunza mugadziri pachine nguva, uye ndapota tsanangura kana uchiodha;
Mamiriro ekushandisa asina kujairika
Kusanganisira iyo yakanyanya kushandiswa nharaunda senge kureba pamusoro pe1000 metres, kukurumidza kuchinja tembiricha, icing pamusoro pe20mm, kusvibiswa kwakanyanya, kunyungudika, ukuvhuvhu, jecha, guruva, kutonhora kwakanyanya, kupisa kunopisa, vibration, kukanganisa, swing, nezvimwe, ndapota taurirana advance kana muchihodha.
