Actastheprotectingandcontrollingunitforgridequipmentsandindustrialminingenterprises'equipments, LW8A-40.5 type outdoor SF6 circuit breaker mudziyo wekunze unoshandiswa mu AC 50HZ matatu-phase 40.5KV emagetsi system.Iyo inoshanda kunzvimbo dzinoda kugara dzichishandiswa mune ratidziro yazvino kana pasi pacho kakawanda pasi / kure pfupi redunhu razvino. Iine iyo yazvino shanduri yekuyera uye yekudzivirira, inogona kutsiva zvakananga SW2-35 isingasviki mafuta wedunhu mudariki uye dzakasiyana siyana oiri wedunhu mudariki ine shanduko bracket. Inogona zvakare kushandiswa seyeti yekudambura uye nekuchinja capacitor boka mamiriro neCT14 mhando yechirimo mashandiro.

Zvimiro
Kwakanaka kuputsa kuita, ipfupi kupisa arc nguva, hupenyu hwakareba;
Mechanical hupenyu hunopfuura 3000 nguva;
Kushanda kazhinji, yega yega inogona kuiswa gumi nemaviri maTransformer;
Nyowani mhando SF6 MKZ pointer mhando density density mita, yekumanikidza gauge kuverenga haina kukanganiswa neshanduko tembiricha;
Mamiriro Ezvakatipoteredza
Ambienttemperature:-30 ℃ ~ + 40 ℃
Kukwirira: ≤3000m
Kumanikidzwa nemhepo: ≤700Pa
Hunyoro hwehukama: zuva nezuva avhareji hama humidity: ≤95%; pamwedzi paavhareji hama humidity≤90; zuva nezuva avhareji yakaguta mweya mweya ≤2.2KPa; pamwedzi paavhareji kukosha ≤1.8KPa
Kusvibiswa kwemweya pamwero: Ⅲ
Kudengenyeka kwenyika kwakasimba: ≤8 degree
Iyo yekumisikidza inofanira kuve isina moto, kuputika, kwakanyanya vibration, chemakemikari ngura uye zvakakomba kusvibiswa
