ZW7-40.5 Series Outdoor High Voltage Vacuum Circuit Breaker

Tsananguro pfupi:

Zw7-40.5 series outdoor high voltage vacuum circuit breaker ine maphase matatu AC 50Hz. Switchgear yekunze ine voltage ine rated voltage ye40.5Kv. Yakashongedzerwa ne spring operating mechanism kana electromagnetic operating mechanism, inogona kudzora kure kupatsanura nekuvhara kwemagetsi, uye inogonawo kuchengetwa nesimba nemaoko, kupatsanura nekuvhara nemaoko. Mashandiro edhizaini anosangana nezvinodiwa zve GB1984 "AC high voltage circuit breaker" national standard, uye inosangana nezvinodiwa zve IEC62271:100 "High voltage AC circuit breaker" International Electrotechnical Commission standard. ZW7-40.5 vacuum circuit breaker inonyanya kushandiswa kudzora nekudzivirira system ye outdoor 35KV power transmission and transformation, uye yakakodzerawo kushandiswa kwakajairika uye kudzivirira short circuit networks dzemagetsi emaguta nemaruwa uye maindasitiri nemakambani emigodhi. Maumbirwo ese echigadzirwa i porcelain pillar type; Bhodhoro repamusoro re porcelain rine vacuum arc extinguishing chamber, uye bhodhoro repasi re porcelain i pillar porcelain bhodhoro. Rakakodzera kushandiswa kwema frequency. Ine hunhu hwekuvhara zvakanaka, kudzivirira kukwegura, kuramba kumanikidzwa kwakanyanya, kusatsva, kusaputika, kushanda kwenguva refu, kuisa nekugadzirisa zviri nyore.
