Ama-Miniature Circuit Breaker: Ukugcina Ama-Safety Circuit Akho Ephephile

Ukubuka konke

I-MCB mini-circuit breakeriyi-AC enemisebenzi eminingi ene-voltage ephansiI-circuit breaker, ngokugcwala ngokweqile, i-short circuit, i-undervoltage kanye nekhono eliqinile lokuphuka.

1. Izici zesakhiwo

• Yakhiwe ngendlela yokudlulisa kanye nohlelo lokuxhumana;
• Izindlela zokudlulisa zihlukaniswe zibe ezenzakalelayo kanye nezindlela zokuhambisa ngesandla;
• Kunezinhlobo ezimbili zezinhlelo zokuxhumana, enye iyindlela yokuxhumana yendabuko, enye iyindlela yokusebenza yentwasahlobo elungisekayo.

2. Ukusebenza kobuchwepheshe

• Inezici zokulayisha ngokweqile, i-short circuit, i-undervoltage kanye nomthamo wokwephuka oqinile;
• Inezici zokuxhumana okuthembekile kanye nesekethe evulekile yesikhathi eside.

3. Imibandela yokusetshenziswa

• Indlela yokufaka: ukufakwa okuhleliwe, ukufakwa kwe-flange;
• Indlela yokuvimbela: izinti ezintathu;
• Ifanele i-AC 50Hz, i-voltage yokushisa elinganiselwe ingu-630V ~ 690V, i-current elinganiselwe ingu-60A ~ 1000A.

Ububanzi Bokusebenza

I-MCBama-mini-circuit breakerszisebenza kakhulu ekungeneni nasekuphumeni kwamanethiwekhi ahlukahlukene okusabalalisa, ikakhulukazi okuhlanganisa:

• Isekethe yokusabalalisa izibani.
• Kusebenza ohlelweni lokusabalalisa amandla njengesivikelo sokulayisha ngokweqile kanye nokujikeleza okufushane kwemigqa;
• Isebenza kuzo zonke izinhlobo zokuvikela ukuqala kwenjini kanye nokubhuleka.
• Kusebenza ekulawuleni izinhlelo zokusetshenziswa kukagesi, njengokukhanyisa, ithelevishini, ucingo kanye nekhompyutha;
• Kusebenza ezindaweni ezingashintshwa njalo noma ezingasetshenziswa njalo ezigabeni.
• Isetshenziswa kakhulu ekuvikeleni umugqa (ukuvikelwa kogesi ongaphezu kwamandla), futhi inikeza umsebenzi wokuvikela wokunqamula ngokushesha ugesi ongalungile wephutha le-short-circuit ku-circuit;
• Ingasetshenziswa njengamadivayisi okuqala nokubopha injini;
• Ingasetshenziswa ekuvikeleni imishini yokuphakelwa kukagesi ngokweqile kanye ne-short circuit;
• Ingasetshenziswa ukuvikela injini kanye ne-transformer ekugcwaleni ngokweqile kanye nokungasebenzisi amandla kagesi anele.

Imibandela Yokusebenzisa

• 1. Izinga lokushisa lomoya elizungezile akufanele lidlule + 40 ℃, futhi akufanele libe ngaphansi kuka - 5 ℃, umswakama ohlobene akufanele udlule u-90%, futhi umswakama ohlobene ophezulu uvunyelwe ekushiseni okuphansi;
• 2, Izinga lokushisa lomoya ozungezile akufanele libe ngaphezu kuka-+ 40 ℃;
• 4, Ukuphakama kwendawo yokufaka akumele kudlule ama-2000m;
• 5, Endaweni ekhululekile engozini yokuqhuma, futhi endaweni engaphakathi akukho gesi noma umusi owanele ukugqwala izinsimbi nokubhubhisa ukufudumala;
• 6, Akukho ukudlidliza okunobudlova, umthelela noma ushintsho oluvamile.
• 9, I-circuit breaker kanye nedivayisi yokumisa isisekelo kungafakwa futhi kuxhunywe ngokwemiyalelo yomkhiqizi noma imininingwane yomkhiqizo;
• 10, I-circuit breaker ingasetshenziswa kanye nezivikelo zokuvuza ezinezinsika ezilodwa kanye nezinsika eziningi ezifakwe kuyo ukuze kwakhiwe idivayisi yokuvikela ukuvuza ehlanganisiwe.

Ukufakwa Kwezintambo kanye Nezinyathelo Zokuqapha

1. Indawo yokufaka:

Izinga lokushisa lomoya ozungezile kufanele libe phakathi kuka-5 ℃ no-40 ℃, ngokuvamile akufanele lidlule + 35 ℃; izinga lokushisa elijwayelekile lamahora angu-24 akufanele lidlule + 35 ℃, futhi umswakama womoya ozungezile akufanele udlule u-50%.

2. Indawo yokufaka:

Uma i-circuit breaker ifakiwe ohlangothini lokungena kwamandla, ukuphela kweswishi ye-circuit breaker kufanele kusekelwe ngokuthembekile, futhi ukumelana kokushisa phakathi kwe-circuit breaker nohlaka lwensimbi olusekelwe kufanele kube ngaphezu kuka-1000MΩ;

Uma i-circuit breaker ifakiwe ohlangothini lokungena kwamandla, ayikwazi ukusekelwa;

3. Imibandela yokusetshenziswa:

I-circuit breaker kufanele ifakwe endaweni yokufaka evundlile noma eqondile. Uma le mfuneko ingakwazi ukufezwa ngenxa yokulinganiselwa kwendawo yokufaka, izinyathelo ezilandelayo zingathathwa:

(1) Oxhumana nabo abasizayo kufanele babekwe ezindaweni ezifanele ebhodini lokugcina lomsabalalisi wangaphambili we-circuit breaker.

Ukufakwa okuvamile 3 ~ 4. Uma i-circuit breaker ingakwazi ukusebenza kahle, ingafakwa isisekelo ngokwethembeka ngokusebenzisa ukuxhumana okusizayo.
