Kodi kusankha MCCB?

Pulasitiki chipolopolo circuit breaker (pulasitiki chipolopolo air insulated circuit breaker) chimagwiritsidwa ntchito kwambiri mu makampani otsika-voltage kugawa, ntchito kudula kapena kudzipatula yachibadwa ndi ovotera osiyanasiyana zolakwika panopa, kuonetsetsa chitetezo mizere ndi zipangizo. malinga ndi zofunikira za "Temporary Power Safety Technical Specification" yaku China, chowotcha chamagetsi kwakanthawi pamalo omanga chiyenera kukhala chipolopolo chowonekera, chimatha kusiyanitsa bwino lomwe malo olumikizirana nawo, ndipo wophwanya chigawo chotsatira ayenera kukhala ndi chizindikiro cha "AJ". yoperekedwa ndi dipatimenti yokhudzana ndi chitetezo.

QF nthawi zambiri amagwiritsidwa ntchito kuimira wophwanya dera, ndipo zojambula zakunja zimatchedwa MCCB.Common pulasitiki chipolopolo dera wosweka tripping njira ndi limodzi maginito tripping, otentha maginito tripping (pawiri), pakompyuta tripping.Single maginito tripping zikutanthauza kuti dera. wosweka amangoyenda pamene dera lili ndi kulephera kwa dera lalifupi, ndipo nthawi zambiri timagwiritsa ntchito kusinthaku mu chowotcha chotenthetsera kapena dera lamagalimoto ndi chitetezo chochulukira. pakali pano wa wosweka dera ulendo, kotero amadziwikanso ngati maulendo awiri, nthawi zambiri amagwiritsidwa ntchito nthawi wamba kagawidwe magetsi. Nthawi yodutsa ndi yosinthika, nthawi zambiri zomwe zimagwiritsidwa ntchito, koma mtengo wamagetsi ozungulira ndi wokwera.Kuphatikiza pa mitundu itatu ya zida zodumphira pamwambapa, pali chodulira chigawo chomwe chimagwiritsidwa ntchito makamaka poteteza dera lamagalimoto.Kuthamanga kwake kwa maginito nthawi zambiri kumakhala kopitilira ka 10 kuposa momwe amachitira kuti apewe nsonga yamagetsi pomwe mota iyamba ndikuwonetsetsa kuti injiniyo iyamba bwino ndipo chowotcha sichikuyenda.

Plastic shell circuit breaker ili ndi zida zosiyanasiyana zomwe zitha kupachikidwa, monga makina osinthira magetsi akutali, koyilo yosangalatsa, kukhudzana kothandizira, kukhudzana ndi alamu, ndi zina zambiri.

Posankha makina ogwiritsira ntchito magetsi, chidwi chiyenera kuperekedwa kwa chotchinga chamagetsi chothandizira pakali pano, chifukwa kukula kwakunja kwa chipolopolo chamagetsi chamakono ndi torque yamakina otseka ndizosiyana.
