Kukula kwa ntchito

Chotsekera magetsi chamagetsi cha CJD (chomwe chimatchedwanso chotsekera magetsi cha CJD) chimagwiritsidwa ntchito popanga ndi kuswa magetsi pamagetsi kapena zida zamagetsi mu makina amagetsi a AC 50Hz kapena 60Hz okhala ndi magetsi ovotera a 250V ndi mphamvu yamagetsi yovotera ya 1A-100A, ndipo chimagwiranso ntchito poteteza kuchuluka kwa magetsi ndi mafunde afupiafupi amagetsi ndi injini. Chotsekera magetsi chimagwiritsidwa ntchito kwambiri pa makompyuta ndi zida zake zozungulira, zida zodziyimira zokha zamafakitale, zida zolumikizirana, mphamvu zolumikizirana ndi zida zamagetsi zosasokonekera za UPS, komanso magalimoto a sitima, makina amagetsi a sitima, makina owongolera elevator ndi zida zamagetsi zosunthika ndi zina zotero. Chimagwira ntchito makamaka m'malo omwe ali ndi mphamvu kapena kugwedezeka. Chotsekera magetsi chikutsatira miyezo ya IEC60934:1993 ndi C22.2.

Zinthu Zogwirira Ntchito Ndi Kukhazikitsa

1. Kutentha kwa mpweya wa chilengedwe: Malire apamwamba ndi +85°C ndipo malire otsika ndi -40°C.
2. Kutalika sikuyenera kupitirira 2000m.
3. Kutentha: Chinyezi cha mpweya pamalo oyika ndi kugwiritsa ntchito circuit breaker sichiyenera kupitirira 50% kutentha kuli +85°C, kutentha kotsika kwambiri pamwezi wonyowa kwambiri sikuyenera kupitirira 25°C, ndipo chinyezi chachikulu cha mweziwo sichiyenera kupitirira 90%.
4. Chotsekera mawaya chingathe kuyikidwa pamalo omwe ali ndi mphamvu komanso kugwedezeka kwakukulu.
5.Pa nthawi yokhazikitsa, kuchuluka kwa chosinthira magetsi chomwe chili ndi malo oyima sikuyenera kupitirira 5°.
6. Chotsekera mawaya chiyenera kugwiritsidwa ntchito m'malo opanda zinthu zophulika komanso opanda mpweya kapena fumbi (kuphatikizapo fumbi loyendetsa) zomwe zingawononge chitsulo kapena kuwononga zotetezera kutentha.
7. Chotsekera ma circuit chiyenera kuyikidwa pamalo opanda mvula kapena chipale chofewa.
8. Gulu lokhazikitsa la chosokoneza ma circuit ndi gulu la ll.
9. Mlingo wa kuipitsidwa kwa chosokoneza magetsi ndi 3 grade.

Maginito a HydraulicChotsegula Dera

Imatha kuthetsa mavuto ambiri opangidwa mwaluso kwambiri, odalirika, komanso okwera mtengo. Ili ndi ubwino wa ma thermal circuit breakers popanda zovuta zake. Poganizira kukhazikika kwa kutentha, hydraulic electromagnetic circuit breaker sikhudzidwa ndi kusintha kwa kutentha kwa chilengedwe. Makina ozindikira ma hydraulic electromagnetic amangoyankha kusintha kwa mphamvu mu circuit yoteteza. Ilibe nthawi yochepetsera kuyankhidwa pang'onopang'ono chifukwa cha overload, komanso ilibe nthawi yoziziritsira isanatsekedwenso pambuyo po overload. Ikapitirira 125% ya katundu wonse, imagwa. Nthawi yochedwetsa ya circuit breaker iyenera kukhala yayitali mokwanira kuti ipewe kugwedezeka molakwika chifukwa cha kusinthasintha kosawononga nthawi yomweyo. Koma pakachitika vuto, kugwa kwa circuit breaker kuyenera kukhala mwachangu momwe zingathere. Nthawi yochedwetsa imadalira kukhuthala kwa madzi onyowa ndi kuchuluka kwa overcurrent, ndipo imasiyana kuyambira ma millisecond angapo mpaka mphindi zingapo. Ndi kulondola kwakukulu, kudalirika, cholinga chapadziko lonse, komanso ntchito zolimba, hydraulic electromagnetic circuit breaker ndiye chipangizo chabwino kwambiri choteteza circuit yokha komanso kusintha mphamvu.
