Ma CJW1 series anzeru a universal circuit breakers angagwiritsidwe ntchito fir kuwongolera ukonde wogawa magetsi otsika ndikusunga chitetezo. Kuyika m'mapanelo ogawa magetsi otsika, imagwira ntchito ngati master switch kuti igwire ntchito yachitetezo chambiri. Chikhalidwe chaukadaulo chafika pamlingo wapamwamba wapadziko lonse lapansi wazinthu zamtunduwu m'zaka za m'ma 1990. Imagwirizana ndi dera la AC 50Hz, voliyumu yovomerezeka ndi 660V (690V) kapena pansi pake, yovotera 400A-6300A.

Wolamulira wanzeru wosiyanasiyana amapereka ntchito zosiyanasiyana.

Zothyola zikutsatira zofunikira za miyezo yotsatirayi, IEC 60947-2, GB14048.2-2001.

Kugawa

Malinga ndi kuyika: kokhazikika ndi kutulutsa
Malinga ndi mitengo: mitengo itatu, mitengo inayi
Malinga ndi njira zogwirira ntchito: injini ndi manja (kukonza ndi kukonza)
Malinga ndi kutulutsidwa: integent over current controller, under-voltage instantaneous (kapena kuchedwa) release, ndi shunt release
Mphamvu ya wolamulira wanzeru wogwiritsa ntchito mphamvu zambiri:
gulu: Mtundu wa H (wabwinobwino), Mtundu wa M (wanzeru wamba), Mtundu wa L (wachuma)
ili ndi ntchito yoteteza malire a nthawi yobwezera mochedwa kwambiri
ntchito yoteteza yokhala ndi nthaka ya gawo limodzi
ntchito yowonetsa: kukhazikitsa chizindikiro chamakono, chizindikiro chamakono cha zochita, chizindikiro chilichonse chamagetsi a waya (muyenera kutchula pamene mukuyitanitsa).

Kutentha kozungulira: -5℃ ~ 40℃, ndipo kutentha kwapakati pa maola 24 pansi pa +35℃ (kupatula maoda apadera).
Malo okwererapo: ≤2000m.
Chinyezi: Osapitirira 50% pa kutentha kwakukulu kwa +40℃. Ngati kutentha kuli kotsika, chinyezi chambiri chimaloledwa, koma kutentha kwapakati kotsika kwambiri pamwezi kosapitirira +25℃ pamwezi wonyowa kwambiri, ndi kuchuluka kwapakati pamwezi kosapitirira 90% pamwezi umenewo, komanso kuganizira za mame pamwamba pa katundu, omwe angawonekere chifukwa cha kusintha kwa kutentha.
Chitetezo cha kuipitsa: madigiri 3.
Magulu okhazikitsa: Ⅳ ya ma circuit akuluakulu a breaker, ma coils a under voltage release ndi ma primary circuit a transformers; Ⅲ ya ma circuit ena othandizira ndi ma control circuit.
Ma breaker omwe amagwiritsidwa ntchito m'zombo ndi m'madera otentha amatha kugwira ntchito bwino popanda kukhudzidwa ndi mpweya wonyowa, chifunga cha mchere ndi bowa.
Zothyola zomwe zimagwiritsidwa ntchito m'zombo zimatha kugwira ntchito modalirika pansi pa kugwedezeka kwabwinobwino.
Chotsekeracho chiyenera kuyikidwa motsatira malangizo omwe ali m'buku la malangizo. Kwa ma breaker omwe amagwiritsidwa ntchito nthawi zambiri, gradient yolunjika siipitirira 50, kwa yomwe imagwiritsidwa ntchito pa sitima, gradient yolunjika siipitirira 22.50.
Chotsekeracho chiyenera kuyikidwa pamalo pomwe palibe chopangira zinthu zophulika komanso fumbi loyendetsa mpweya komanso palibe mpweya, womwe ungawononge chitsulo kapena kuwononga chotenthetsera.
Chotsekeracho chiyenera kuyikidwa m'chipinda cha switchboard ndipo chimango cha chitseko chiyenera kukhazikikanso, mulingo woteteza ndi mpaka lP40.
