Overview
FLN36-12D indoor high-voltage AC load switch is medium-voltage switchgear yakagadziridzwa nekambani yedu tichitarisa kune dzimwe nyika matekinoroji uye zvinoenderana nemazinga akakodzera esimba renyika yangu.2004 “3.6kV-40.5kV High Voltage AC Load Switch”, GB1985-2004 “High Voltage AC Isolation Switch and Earthing Switch”, GB/T11022-1999 “Common Technical Requirements for High Voltage Switchgear and Control Equipment, ndiyo mitemo. ye ring network cabinet.main switching element.Iyo inotakura switch ndeye yakawanda-inoshanda yepakati-voltage switchgear inobatanidza gedhi, kuvhura uye pasi.Iyo yakazadzwa neSF6 gasi re0.05MPa mune yakavharwa yakazara epoxy resin shell ine yakasimbiswa chimiro, uye zviri pamusoro zvinowanikwa nezvikamu zvidiki.Mabasa matatu anovimbisa kunaka kwechigadzirwa uye anovandudza kuvimbika.Kuchengetedza-pasina, kushanda kwakachengeteka kweanopfuura makore makumi maviri pasi pemamiriro akajairika.
Shandisa Environmental Conditions
a) Kukwirira hakupfuuri 1000m;
b) Ambient tembiricha yemhepo: yepamusoro muganhu +40, yakaderera muganho -25ºC;
c) Hunyoro hunyoro: muvhareji wezuva nezuva hausi kupfuura 95%, uye muvhareji wepamwedzi hausi kupfuura 90%;
d) Mhepo yakatenderedza haina kusvibiswa negasi rinoparadza kana gasi rinopisa, mhute yemvura, nezvimwewo;
e) Hapana kudengenyeka kunogara kuchiitika.
