Kodi zolakwika za ma air circuit breakers (ACB) ndi ziti?

1. Chotsekera mpweya chinagwa ndipo chinalephera kutsekanso:
Choyamba, dziwani ngati chothyola mpweya chinagwa popanda ngozi. Kugwa popanda ngozi kumatanthauza kuti chinagwa popanda vuto la short circuit kapena overload. Pali zifukwa zambiri zomwechoswa dera la mpweyaSizingatseke. Choyamba, ndikofunikira kudziwa ngati ulendowu wachitika chifukwa cha kufupika kwa magetsi ndi kupitirira muyeso, kapena ngati choswa magetsi chokha kapena chowongolera magetsi chili ndi vuto. Tsatirani njira zotsatirazi kuti mudziwe chomwe chayambitsa vuto. Choyamba, yang'anani ngati dera loyamba lakhala ndi mawaya akuda kapena oyaka ndi zolumikizira, fungo ngati pali fungo lapadera, komanso ngati pali vuto lililonse mu dera lolamulira lachiwiri loyenera mu kabati yamagetsi otsika. Ngati malo olakwika apezeka, amatha kugwira ntchito bwino atachotsedwa; ngati palibe malo olakwika odziwika bwino omwe apezeka, choswa magetsi chimatsekedwa popanda kunyamula katundu. Ngati choswa magetsi chagundidwa ndipo sichingayambe kugwira ntchito, choswa magetsi cha mpweya chokha chili ndi vuto; Ngati choswa magetsi chatsekedwa, palibe vuto mu choswa magetsi cha nthambi. Kenako zolakwika za mzere wa nthambi zimapezeka motsatizana.
2. Kulephera kwa chowongolera chanzeru cha choswa dera la mpweya:
Pambuyo poti chowongolera chanzeru cha chotseka ma air circuit breaker chalephera, vuto la kutseka kwamanja, kutseka kwamagetsi, ndi kulephera kwa ntchito yoteteza ya magawo atatu ndi ntchito zina zoteteza nthawi zambiri zimachitika. Kulephera kwanzeru kwa chowongolera nthawi zambiri kumachitika chifukwa cha kutentha kwambiri chifukwa cha magetsi ambiri. Nthawi zambiri, opanga amatsatira miyezo yoyenera yadziko lonse ndikupanga magetsi ogwirira ntchito ovoteledwa kukhala 400V. Komabe, pakugwira ntchito kwenikweni, mphamvu ikachepa pakati pausiku, ngati chosinthira sichikulamulidwa ndi magetsi, magetsi nthawi zambiri amafika 420V ndi kupitirira apo. Mphamvu yayikulu imapangitsa chowongolera chanzeru kuzima chifukwa cha magetsi ambiri. Vuto lina lofala la chowongolera ndilakuti ngati kukumbukira zolakwika sikunachotsedwe panthawi yake, ngakhale cholakwika cha gridi yamagetsi chitatha, chotseka ma circuit breaker chidzaganizabe kuti gridi yamagetsi ndi yolakwika ndipo palibe buku lamanja kapena chotseka ma circuit breaker chomwe chidzatseke chotseka ma circuit breaker. Pakadali pano, mutha kugwira ntchito mwachizolowezi potsatira ntchito zomwe zili m'buku la malangizo, kuchotsa kukumbukira zolakwika ndikuyiyikanso. Anthu wamba sangaganize kuti ndi chifukwa chakuti chipata sichingatsekedwe, ndipo nthawi zambiri sangapeze chomwe chayambitsa vuto, kapena amadziwa chomwe chayambitsa, koma chifukwa ntchito yoyeretsa ndi yovuta kwambiri, amatha kupeza akatswiri akatswiri okha, zomwe zimapangitsa kuti magetsi azizimitsidwa mosafunikira. Yankho lake ndilakuti opanga ma air circuit breaker apange ma controller okhala ndi mphamvu yolimba yomwe ndi yosavuta komanso yosavuta kugwiritsa ntchito, komanso nthawi yomweyo kulimbikitsa maphunziro aukadaulo kwa ogwiritsa ntchito.
