ZW20-12F 630A 1000A 12KV mzere chitetezo chochulukira odzipereka panja mkulu voteji vacuum circuit breaker

ZW20-12F panja AC HV vacuum boundary circuit breaker (yomwe imadziwika kuti boundary circuit breaker) ndi imodzi mwazinthu zathu zatsopano.Boundary circuit breaker ndi chida chanzeru chogwira ntchito zambiri chomwe chimakhala ndi vacuum breaker, vacuum load switch, recloser, sectionalizer masiwichi anayi.Kusintha kwakukulu kumakhala ndi vacuum breaker, chowongolera cha CH-40, chosinthira chamagetsi chakunja (Zindikirani: ma network a ring ring network omwe amapezeka mumayiko awiri a PT) magawo atatu.
Zogulitsa zimagwiritsidwa ntchito kwambiri mu 10kV, mzinda wa 13kV, netiweki yamagetsi yakumidzi yakumidzi yolumikizira switch, switch switch, chida chosinthira chodziwikiratu chomwe chitha kukhazikitsa mzere wotumizira mphete.Itha kugwiritsidwa ntchito ngati switch yamalire (yomwe imadziwika kuti watchdog) mumzere wanthambi yamagetsi, yomwe imagwiritsidwa ntchito ngati ma reclosers ndi zigawo mumaneti ogawa chakudya cham'mwamba.Boundary circuit breaker yokhala ndi kachitidwe kakutali, chitetezo ndi ntchito zowongolera ndi ntchito zolumikizirana.Kuzindikira kodalirika pakuweruza, kutsata kwa mA mulingo wa zero pakalipano ndi kufupikitsa kwapakati pa magawo, kuzindikira kuchotsedwa kwapang'onopang'ono kwa gawo limodzi ndi gawo lolakwika laling'ono.Chosinthira chachikulu ndi vacuum arc ndi kutchinjiriza kutengera SF6, N2 mpweya wosakanikirana.Mlandu woyambitsa Japan, Germany, kusindikiza gasi waku France, umboni wa kuphulika, ukadaulo waukadaulo wamakina, ntchito yabwino kwambiri yosindikiza.Mkati mwadzaza ndi SF6, N2 gasi wosakanizidwa omwe samataya, osakhudzidwa ndi chilengedwe chakunja.Makina ogwiritsira ntchito masika okhala ndi miniaturization ndi kukhathamiritsa kwa magwiridwe antchito, kudalirika kwa zochita ndikokwera kwambiri kuposa momwe zimakhalira masika.
