ZW7-40.5 Outdoor High Voltage Vacuum Circuit Breaker

Mwachidule

ZW7-40.5 panja voteji malonda AC vacuum circuit breaker ili ndi ubwino wa ntchito yotetezeka komanso yodalirika, kukonza kosavuta komanso nthawi yayitali yokonza.Chifukwa chogwiritsa ntchito kudzaza zida zatsopano zotsekera, mawonekedwe onse a chosinthira chosasunthika kunja kwa chipinda chozimira cha arc ndi khoma lamkati la manja a porcelain amayikidwa mu bokosi la makina, lomwe ndi losavuta kukhazikitsa.Imapewanso zovuta zamafuta, kutayikira kwa gasi ndi kawopsedwe ka ma switch ena.Chifukwa zolumikizana zosunthika komanso zosasunthika za wophwanya dera zimasindikizidwa mu chipinda chozimitsa cha vacuum arc, ndipo chopukutiracho chimagwiritsidwa ntchito ngati sing'anga yotsekereza ndi sing'anga yozimitsira arc, ili ndi maubwino angapo omwe mitundu ina ya masinthidwe sangafanane.Chifukwa chake mankhwalawa ndi chinthu chabwino kuti alowe m'malo mwa DW multi-mafuta circuit breaker.Mapangidwe a bokosi la makina ogwiritsira ntchito la mankhwalawa pakati pa ophwanya dera ndi chapakati champhamvu chamagetsi chamagetsi chamagetsi.Mtundu woterewu wamtunduwu ndi wamfupi wa 260mm kuposa woyendetsa dera woyambirira, ndipo ndi woyenera kuyika m'malo opanda malo ochepa.
Izi ndi zoyenera kwa 40.5kV, 50.Hz magawo atatu amagetsi ogawa mphamvu, monga katundu wamakono, wodzaza panopa komanso wafupipafupi wamakono ndi siteshoni.

Ntchito Yaikulu

◆ Kugwiritsa ntchito chozimitsa cha vacuum arc.Kuthyoka kwamphamvu, moyo wautali wamagetsi, ndi moyo wamakina nthawi 10,000:
◆ Kapangidwe kosavuta, kopanda kukonza, nthawi yayitali yosakonza;
◆ Kuchita bwino kwa kutchinjiriza komanso kuthekera kolimba kotsutsana ndi kuipitsa;
◆ Itha kukhala ndi zida kapena zida zamagetsi zamagetsi zogwirira ntchito, zokhala ndi makina odalirika komanso kugwira ntchito pafupipafupi;palibe zoopsa za moto ndi kuphulika;
◆ Transformer yamakono yomangidwa, kulondola kwa mphunzitsi kumafika ku 0.2, komwe kungathe kuzindikira chitetezo cha magawo atatu;
◆ Wowongolera condensing amamangiriridwa, omwe amatha kusunga dera lotseguka ndikugwira ntchito modalirika pansi pa kutentha ndi chinyezi china.

Gwiritsani Ntchito Zachilengedwe

◆ Kutentha kwa mpweya wozungulira: malire apamwamba +40 ℃, malire otsika -30 ℃;
◆ Kutalika: 200.0m (ngati kutalika kuyenera kuwonjezereka, mlingo wotsekemera wotsekemera udzawonjezeka moyenerera),
◆ Kuthamanga kwa mphepo: osapitirira 700.Pa (yofanana ndi liwiro la mphepo 34m/s),
◆ Matalikidwe: mphamvu ya seismic B digiri z
◆ Mulingo wa kuipitsidwa: Ⅲ mulingo;
◆ Kusiyana kwakukulu kwa kutentha kwa tsiku ndi tsiku: osapitirira 25 ℃
