Kuzo zonke izinhlelo zikagesi, ukuphepha nokuvikelwa kufanele kube yinto eza kuqala ngaso sonke isikhathi. Yilapho-keI-MCCB or I-Molded Case Circuit BreakerKungena. Lezi yizingxenye ezibalulekile ekuvikeleni imishini kagesi, amasekethe kanye nezintambo kumasekethe adlulayo kanye namafushane, ukuvimbela izingozi zikagesi kanye nomonakalo wemishini.
Ama-MCCBama-circuit breaker esimanje anikeza izinzuzo eziningana kunezinhlobo zendabuko nezindala ze-ama-circuit breakerKule bhulogi, sizohlola izinzuzo zokusebenzisa ama-MCCB ezinhlelweni zikagesi nokuthi angasiza kanjani ekuqinisekiseni ukusebenza kukagesi okuthembekile nokuphephile.
1. Umthamo omkhulu wokuphuka
Ama-MCCB anamandla okuphula aphezulu, okuyinani eliphezulu lamandla kagesi angaliphazamisa ngokuphephile. Ama-MCCB anamandla okuphula aphezulu futhi angaphatha ama-current e-short-circuit afinyelela kumashumi ama-kiloampere (kA). Lokhu kusho ukuthi angahlukanisa amaphutha ngokushesha futhi avimbele umonakalo kumayunithi nemishini engezansi komfula. Amandla okuphula aphezulu asho nokuthi ama-MCCB angaphatha imithwalo emikhulu, okwenza izinhlelo zikagesi zisebenze emazingeni aphezulu amandla.
2. Ukuhlelwa kohambo okulula
I-MCCB inezilungiselelo zohambo ezilungisekayo ezivumela ukuthi zilungiselelwe izidingo ezithile zohlelo lokusebenza. Lezi zilungiselelo zisukela kumayunithi ohambo olusebenzisa amandla kagesi kuya kumayunithi ohambo olusebenzisa amandla kagesi futhi zivumela i-MCCB ukuthi iphendule ezimweni ezahlukene zokusebenzisa amandla kagesi njenge-short circuit noma i-overload. Besebenzisa i-MCCB, abasebenzisi bangalungisa izilungiselelo ukuze banikeze izinga lokuvikela elifunekayo futhi bathuthukise ukusebenza kahle kwesistimu yabo kagesi.
3. Ukuvikelwa kwamandla kazibuthe okushisa
Ama-MCCB ahlinzeka ngenhlanganisela yokuvikelwa kokushisa kanye nokwe-magnetic. Izinto zohambo lokuvikela ukushisa zisabela ekugcwaleni ngokweqile, kuyilapho izinto zokuvikela amandla kazibuthe zisabela ezijikelezweni ezimfushane. Indlela yohambo isabela kakhulu futhi izosebenza ngokushesha ngokusekelwe esimweni sokushisa ngokweqile. Uma kufakwa i-MCCB, uhlelo lukagesi luzuza ekuvikelweni okuthuthukisiwe ekulimaleni kokushisa kanye nokwe-magnetic.
4. Umklamo omncane
Inzuzo enkulu yeI-MCCBumklamo wayo omncane. Athatha isikhala esincane kuneziphuli zesekethe zesitayela esidala futhi angaboshelwa noma axhunywe ku-DIN rail, okusindisa isikhala esibalulekile samaphaneli. Umklamo omncane wenza futhi i-MCCB ibe lula, kunciphisa izindleko zokuthumela futhi kwenze kube lula ukuyiphatha nokuyifaka.
5. Amakhono okuqapha nokuxhumana athuthukisiwe
Ama-MCCB anamuhla afaka ubuchwepheshe obuthuthukisiwe be-microprocessor, obuwenza akwazi ukuxhumana namanye amadivayisi nezinhlelo. Ama-MCCB aqapha futhi aqophe amapharamitha afana nokusetshenziswa kwamandla kagesi, i-voltage, amandla, kanye nokusetshenziswa kwamandla, okusiza abaqhubi kanye nonjiniyela ukukala impilo iyonke yezinhlelo zikagesi. Ngaphezu kwalokho, amakhono okuxhumana avumela ama-MCCB ukuthi axhumane nezinhlelo zokuqapha, zokulawula kanye nezokuzenzakalela, okuthuthukisa ukuphathwa nokusebenza kwezinhlelo zikagesi.
6. Iqinile futhi ithembekile
Ama-MCCB aklanyelwe ukumelana nezimo ezinzima futhi angasebenza emazingeni okushisa asukela ku--25°C kuya ku-+70°C. Enziwe ngezinto ezisezingeni eliphezulu ezingamelani nokuguguleka kwamakhemikhali nokwemishini, njenge-polycarbonate, i-polyester kanye ne-ceramic. Ngaphezu kwalokho, ama-MCCB ahlala isikhathi eside kakhulu, ahlala iminyaka eyi-10 kuya kwengama-20 kuye ngokusetshenziswa kwawo kanye nokugcinwa kwawo.
7. Isicelo semisebenzi eminingi
Ama-MCCB anezinhlelo zokusebenza eziningi, kusukela kuma-voltage aphansi kuya kuma-voltage aphezulu. Ayingxenye ebalulekile yokuvikela nokulawula ama-motor, ama-generator, ama-transformer kanye neminye imishini kagesi ebalulekile. Ama-MCCB nawo angumugqa wokuqala wokuzivikela ekwakheni izinhlelo zikagesi, iziteshi ezincane, izimboni ezinkulu kanye nezitshalo zikagesi.
Ekuphetheni
Ama-MCCB angama-circuit breaker athembekile, asebenzayo futhi aphephile adlala indima ebalulekile ezinhlelweni zikagesi. Ahlinzeka ngokuvikelwa okudingekayo kwemishini, izintambo kanye nabasebenzi ezingozini kanye nomonakalo obangelwa yi-overcurrents kanye nama-short circuits. Izilungiselelo zokuhamba ezithuthukisiwe ze-MCCB, ukuvikelwa kwe-thermal magnetic, ukwakheka okufushane, izici zokuqapha, ukuqina kanye nokuguquguquka kwenza kube ukukhetha okuhle kunoma yiluphi uhlelo lukagesi. Ukuqinisekisa ukusebenza kukagesi okuthembekile nokuphephile, shintshela kuma-MCCB bese uzwa izinzuzo ezinikezayo.
