Chigadzirwa Chimiro
ZW7A-40.5 Series yekunze yakakwira voltage vacuum circuit breakers main switchgear yeAC50Hz, 40.5KV, iyo yakaunganidzwa nechitubu chekushandisa kana electromagnetic inoshanda mashini.Inogona kushandiswa kushandura / kudzima neremote control, uye zvakare inochajwa uye kudzima / kudzima neruoko.Iyo dhizaini basa rebreaker rinoenderana nezvinodiwa zveGB1984-89 uye IEC56 "AC high voltage circuit breaker", inonyanya kushandiswa kunze kwe35KV kugovera sisitimu yekudzora nekudzivirira, zvakare kune yakajairika kushanda uye kudzivirira pfupi dunhu remadhorobha, kumaruwa network. , kana maindasitiri emaindasitiri.Chimiro chayo chese chinotsigirwa neporcelain insulator, vacuum interrupter yakavakirwa mukumusoro insulator, yakadzika insulator inoshandiswa kutsigira.The breaker inoshanda
kazhinji nzvimbo dzekushanda dzine zvakanakira kuvhara-kuchembera kwakanaka, yakakwira-voltage inomira, isina murazvo, isina kuputika hupenyu hurefu hwekushanda, kuisirwa nyore uye kugadzirisa uye nezvimwe.
Chigadzirwa chimiro
Kune nzvimbo yekushanda kakawanda
Kuiswa chisimbiso kwakanaka, anti-kuchembera, kudzvanywa, kusatsva, hapana kuputika, hupenyu hurefu, kuiswa nyore uye kugadzirisa maitiro.
Vacuum circuit breaker ambient condition
1, Altitude: haipfuure 1000m
2, Ambient tembiricha: kwete pamusoro +40 ° C, kwete pasi - 15 ° C
3, Hunyoro hunyoro: avhareji yemazuva ese humidity: ≤95%; pamwedzi avhareji hunyoro hunyoro :≤95%; pamwedzi avergae hunyoro hunyoro ≤90%, zuva nezuva avergae yakazara mhute kumanikidza ≤2.2KPa; pamwedzi wepakati kukosha: ≤1.8K.
4, Kudengenyeka kwepasi: ≤8 dhigirii
5, Kuiswa kwacho kunofanirwa kunge kusina moto, kuputika, kuzununguka kwakanyanya, kuora kwemakemikari uye kusvibiswa kwakakomba.
