1.Outline

VSM-12 akatevedzana anogara magineti-mhando yemukati yakakwira voltage vacuum wedunhu breaker itatu-chikamu AC 50Hz, yakayerwa voltage ye12kV yemukati switch michina. Yakaiswa nekusingaperi magineti meshini yekambani yedu pachedu yekutsvagisa uye kusimudzira kwemaindasitiri uye emigodhi mabhizinesi, kugadzirwa kwemagetsi uye substation zvivakwa semagetsi ekudzora uye kudzivirira zvinangwa. Chigadzirwa chine kuvimbika kwepamusoro uye hunhu hurefu hwehupenyu, kunyanya hunoshanda kunzvimbo dzine mamiriro akakomba, senge nguva zhinji kushanda, inodzokororwa pfupi-yedunhu breaking current.

2.Environmental Conditions

◆Ambient tembiricha: -25℃~+40℃;

◆Altitude: ≤1000m, plateau type ≤3000m;

◆Hunyoro hunyoro: avhareji yemazuva ese ≤95%, avhareji yepamwedzi ≤90%, yakazara mhute yekumanikidza zuva nezuva

avhareji ≤2.2×10 MPa, avhareji yemwedzi ≤1.8×10MPa. Apo tembiricha inodonha nekukurumidza panguva

high tembiricha nguva, zvinogona kuitika condensation.

◆Kudengenyeka kwepasi: ≤8 level;

◆Nzvimbo dzisina moto, njodzi yekuputika, tsvina yakakomba, kuora kwemakemikari, pamwe nekunyanya

vibration.
