Frame circuit breaker (ACB)

Frame circuit breaker imatchedwanso universal circuit breaker.Ziwalo zake zonse zimayikidwa muzitsulo zotsekedwa, zomwe nthawi zambiri zimakhala zotseguka.Ikhoza kukhala ndi zipangizo zosiyanasiyana.Ndi yabwino m'malo kulankhula ndi zigawo zikuluzikulu, ndipo makamaka ntchito lophimba waukulu kumapeto mphamvu.Pali ma elekitiromagineti, zamagetsi ndi zanzeru kutulutsidwa kwakanthawi.Wowononga dera ali ndi zigawo zinayi zachitetezo: kuchedwa kwanthawi yayitali, kuchedwa kwakanthawi, nthawi yomweyo ndi vuto la pansi.Kuyika kwa chitetezo chilichonse kumasinthidwa mumtundu wina molingana ndi chipolopolo chake.
Chowotcha chimango chimagwiritsidwa ntchito pa intaneti yogawa ndi AC 50Hz, voliyumu yovotera ya 380V ndi 660V, ndipo idavotera 200a-6300a.Amagwiritsidwa ntchito makamaka kugawira mphamvu zamagetsi ndikuteteza mizere ndi zida zopangira magetsi kuchokera pakuchulukirachulukira, kutsika pang'ono, kuzungulira kwafupipafupi, kukhazikika kwa gawo limodzi ndi zolakwika zina.Wowononga dera ali ndi ntchito zingapo zoteteza mwanzeru ndipo amatha kupeza chitetezo chosankha.M'mikhalidwe yabwinobwino, itha kugwiritsidwa ntchito pakusintha mizere pafupipafupi.Wowononga dera pansi pa 1250A angagwiritsidwe ntchito kuteteza mochulukira ndi dera lalifupi la injini mu netiweki ndi AC 50Hz voteji ya 380V.
Chowotcha chamtundu wa chimango chimagwiritsidwanso ntchito nthawi zambiri pamzere waukulu wotuluka, masinthidwe otayira mabasi, chosinthira chachikulu chamagetsi ndi chosinthira chachikulu chamagalimoto kumbali ya 400V ya thiransifoma.

Mtundu wathu wamtundu wa Yuye wowononga chimango waphimba mafunde onse ovotera, mpaka 6300A, ndipo wadutsa chiphaso cha CQC.

Basic khalidwe magawo a circuit breaker

(1) Ovotera voteji ntchito Ue

Ma voliyumu ogwiritsira ntchito ovotera amatanthawuza mphamvu yamagetsi yamagetsi yamagetsi, yomwe imatha kugwira ntchito mosalekeza pansi pamikhalidwe yodziwika bwino yogwiritsidwa ntchito ndi magwiridwe antchito.
China imanena kuti mphamvu yogwira ntchito kwambiri ndi nthawi 1.15 ya voteji yamagetsi pamagetsi a 220kV ndi pansi;Mphamvu yamagetsi ya 330kV ndi kupitilira apo ndi nthawi 1.1 ya voteji yomwe idavotera ngati mphamvu yogwira ntchito kwambiri.Wophwanyira dera amatha kusunga kusungunula pansi pamagetsi othamanga kwambiri pamakina, ndipo amatha kupanga ndikuswa molingana ndi zomwe zanenedwa.

(2) Idavoteredwa pano (mu)

Zovoteledwa pano zimatanthawuza zapano zomwe kutulutsidwako kumatha kwa nthawi yayitali pomwe kutentha kozungulira kuli pansi pa 40 ℃.Kwa wophwanyira dera wokhala ndi kumasulidwa kosinthika, ndiye pakali pano kuti kumasulidwa kungadutse kwa nthawi yayitali.
Kutentha kozungulira kupitilira 40 ℃ koma osapitilira 60 ℃, kumaloledwa kuchepetsa katundu ndikugwira ntchito kwa nthawi yayitali.

IR

Ngati mphamvuyo ipitilira mtengo wamakono wa IR wa kumasulidwa, wosokoneza dera amachedwa kugunda.Imayimiranso kuchuluka kwaposachedwa komwe wophwanya dera amatha kupirira popanda kudumpha.Mtengowu uyenera kukhala wokulirapo kuposa kuchuluka kwa katundu wapano wa IB koma kuchepera pamlingo womwe umaloledwa ndi mzerewu.
Thermal disconnect relay IR ikhoza kusinthidwa mumitundu ya 0.7-1.0in, koma ngati zida zamagetsi zikugwiritsidwa ntchito, zosinthazo zimakhala zazikulu, nthawi zambiri 0.4-1.0in.Kwa wophwanyira dera wokhala ndi zosasinthika zapaulendo wodutsa, IR = mkati.

(4) Kutulutsa kwafupipafupi kutulutsa mtengo wamakono im

Kuthamanga kwafupipafupi (kuchedwa kapena kuchedwa kwafupipafupi) kumagwiritsidwa ntchito kuthamangitsa woyendetsa dera mwamsanga pamene vuto lalikulu likuchitika, ndipo malire ake ndi im.

(5) Kuyesedwa kwakanthawi kochepa kupirira ICW yamakono

Zimatanthawuza mtengo wamakono womwe umaloledwa kudutsa mkati mwa nthawi yomwe mwagwirizana.Mtengo wamakono udzadutsa mwa woyendetsa mkati mwa nthawi yogwirizana, ndipo woyendetsayo sadzawonongeka chifukwa cha kutentha.

(6) Kuphwanya mphamvu

Kutha kwa kusweka kwa wophwanyira dera kumatanthawuza kutha kwa wowononga dera kuti adule motetezeka pakali pano, zomwe sizikugwirizana kwenikweni ndi zomwe zidavotera.Pali 36ka, 50kA ndi zina.Nthawi zambiri imagawika kukhala ma ICU odumphadumpha pang'onopang'ono ndikugwiritsa ntchito ma IC odumpha pang'ono.
