Kev Piav Qhia Luv:

ZW7-40.5 series sab nraum zoov high voltage vacuum circuit breaker yog peb-theem AC 50Hz. Sab nraum zoov high-voltage switchgear nrog rated voltage ntawm 40.5Kv. Nruab nrog lub caij nplooj ntoos hlav ua haujlwm mechanism lossis electromagnetic operating mechanism, nws tuaj yeem tswj hwm qhov hluav taws xob faib thiab kaw, thiab kuj tuaj yeem khaws cia lub zog, faib thiab kaw tes. Kev tsim qauv ua tau raws li cov cai ntawm GB1984 "AC high voltage circuit breaker" tus qauv hauv tebchaws, thiab ua tau raws li cov cai ntawm IEC62271: 100 "High voltage AC circuit breaker" International Electrotechnical Commission tus qauv. ZW7-40.5 vacuum circuit breaker feem ntau yog siv rau kev tswj hwm thiab kev tiv thaiv ntawm sab nraum zoov 35KV fais fab kis thiab hloov pauv system, thiab kuj tsim nyog rau kev ua haujlwm ib txwm thiab luv luv circuit tiv thaiv ntawm cov nroog thiab cov nroog nyob deb nroog faib hluav taws xob network thiab kev lag luam thiab cov chaw ua haujlwm mining. Cov qauv tag nrho ntawm cov khoom yog porcelain pillar hom; Lub raj mis porcelain sab saud muaj lub tshuab tua hluav taws xob arc, thiab lub raj mis porcelain sab hauv qab yog lub raj mis porcelain pillar. Haum rau kev ua haujlwm zaus. Nws muaj cov yam ntxwv ntawm kev sib khi zoo, tiv thaiv kev laus, tiv taus siab, tsis muaj combustion, tsis muaj kev tawg, lub neej ntev, kev teeb tsa yooj yim thiab txij nkawm.
