Tsanangudzo Yemuenzaniso

Chigadzirwa technical parameters uye ekunze zviyero

Chigadzirwa chimiro maitiro

1.Iyo nzira yekushanda inotangwa nzira yekushanda kubva kuSiemens 3AF vacuum circuit breaker, iyo inoshandiswa inoshandiswa inosanganiswa nevhavha yemagetsi, ine maitiro emigwagwa mapfupi ekufambisa, mashoma maketani uye kushanda kwepamusoro.
2.This operating mechanism inotora spring type, inogona kushandiswa ne AC kana DC, inogonawo kushandiswa nebhuku.

Mamiriro ekunze

1. Ambient tembiricha yemhepo: -5~+40 uye avhareji tembiricha haifanire kudarika +35 mu24h.
2. Isa uye shandisa mumba.Altitude pamusoro pegungwa rekushanda saiti haifanire kudarika 2000M.
3. Hunyoro hunyoro haufanire kudarika 50% pamatembiricha epamusoro +40.Hunyoro hwepamusoro hunobvumirwa pane tembiricha yakaderera.Ex.90% pa +20.Asi tichifunga nezvekuchinja kwetembiricha, zvinokwanisika kuti dova rine mwero richangobuda zvaro.
4. Kuiswa gradient kusapfuure 5.
5. Isa munzvimbo dzisina kudengenyeka kunotyisa uye kuvhunduka uye nzvimbo dzisina kukwana kuti dziparadze zvikamu zvemagetsi.
6. Chero chipi zvacho chinodiwa, bvunza ne manufactory.
