Kuzo zonke izinhlelo zikagesi, ukuphepha nokuvikela kufanele kube yinto ehamba phambili ngaso sonke isikhathi.Yilapho i-I-MCCB or I-Molded Case Circuit Breakeringena. Lezi yizingxenye ezibalulekile ekuvikeleni okokusebenza kukagesi, amasekhethi nezintambo kumasekhethi adlulele kanye namafushane, ukuvikela izingozi zikagesi nokulimala kwemishini.
Ama-MCCBskukhona ama-circuit breaker anamuhla anikeza izinzuzo eziningana ngaphezu kwezinhlobo zendabuko nezindala zeama-circuit breakers.Kule bhulogi, sizohlola izinzuzo zokusebenzisa ama-MCCB ezinhlelweni zikagesi nokuthi angasiza kanjani ukuqinisekisa ukusebenza kukagesi okuthembekile nokuphephile.
1. Umthamo omkhulu wokuphuka
Ama-MCCB anamandla okuphuka okuphezulu, okuyinani eliphezulu lamanje angaliphazamisa ngokuphephile.Ama-MCCB anomthamo omkhulu wokuphuka futhi angakwazi ukuphatha ama-short-circuit currents afika emashumini ama-kiloamperes (kA).Lokhu kusho ukuthi bangakwazi ukuhlukanisa ngokushesha amaphutha futhi bavimbele ukulimala kumayunithi namathuluzi aphansi komfula.Umthamo omkhulu wokuphuka uphinde usho ukuthi ama-MCCB angakwazi ukuphatha imithwalo emikhulu, okwenza amasistimu kagesi asebenze kumazinga aphezulu wamandla.
2. Ukulungiselelwa kohambo olulula
I-MCCB inezilungiselelo zohambo ezilungisekayo ezivumela ukuthi ilungiselwe izidingo ezithile zohlelo lokusebenza.Lezi zilungiselelo zisukela kumayunithi wohambo kazibuthe oshisayo ukuya kumayunithi ohambo lwe-elekthronikhi futhi zivumela i-MCCB ukuthi iphendule ezimeni ezidlulele ezihlukile ezifana nokujikeleza okufushane noma ukulayishwa ngokweqile.Besebenzisa i-MCCB, abasebenzisi bangakwazi ukushuna izilungiselelo ukuze banikeze izinga elifunekayo lokuvikela futhi bathuthukise ukusebenza kahle kwesistimu yabo kagesi.
3. Ukuvikelwa kazibuthe ezishisayo
Ama-MCCB ahlinzeka ngenhlanganisela yesivikelo esishisayo nesikazibuthe.Izinto zohambo lokuvikela okushisayo zisabela ekulayisheni ngokweqile, kuyilapho izici zokuvikela kazibuthe ziphendula kumasekhethi amafushane.Indlela yohambo iyasabela kakhulu futhi izothatha isinyathelo ngokushesha ngokusekelwe esimweni sokudlula isikhathi.Uma i-MCCB ifakiwe, isistimu kagesi izuza ekuvikelweni okuthuthukisiwe emonakalweni oshisayo nokazibuthe.
4. Umklamo ohlangene
Inzuzo enkulu yeI-MCCBumklamo wayo ohlangene.Athatha isikhala esincane kunesitayela esidala se-circuit breaker futhi angafakwa ibhawudi noma ashunwe kumzila wesitimela we-DIN, konga isikhala sephaneli esibalulekile.Idizayini ehlangene yenza i-MCCB ibe lula, inciphise izindleko zokuthumela futhi ikwenze kube lula ukuyiphatha nokuyifaka.
5. Amakhono athuthukisiwe okuqapha nawokuxhumana
Ama-MCCB esimanje ahlanganisa ubuchwepheshe obuthuthukisiwe be-microprocessor, obubenza bakwazi ukuxhumana namanye amadivaysi namasistimu.Ama-MCCB aqapha futhi aqophe amapharamitha afana namanje, amandla kagesi, amandla, kanye nokusetshenziswa kwamandla, ukusiza opharetha nonjiniyela ukukala impilo yonke yamasistimu kagesi.Ukwengeza, amandla okuxhumana avumela ama-MCCB ukuthi axhumane nokuqapha, ukulawula kanye nezinhlelo ezizenzakalelayo, ukuthuthukisa ukuphathwa nokusebenza kwesistimu kagesi.
6. Imangelengele futhi inokwethenjelwa
Ama-MCCB aklanyelwe ukumelana nezindawo ezinokhahlo futhi angasebenza emazingeni okushisa asukela ku -25°C kuya +70°C.Zenziwe ngezinto ezisezingeni eliphakeme ezimelana nokugqokwa kwamakhemikhali nemishini, njenge-polycarbonate, i-polyester ne-ceramic.Ngaphezu kwalokho, ama-MCCB aphila isikhathi eside kakhulu, ahlala iminyaka eyi-10 kuye kwengama-20 kuye ngokusetshenziswa kwawo nokugcinwa kwawo.
7. Isicelo esinemisebenzi eminingi
Ama-MCCB anezinhlobonhlobo zezicelo, kusukela ku-voltage ephansi kuya kumasistimu kagesi kagesi aphezulu.Ziyingxenye ebalulekile yokuvikela nokulawula izinjini, amajeneretha, ama-transformer nezinye izinto zikagesi ezibalulekile.Ama-MCCB nawo awumugqa wokuqala wokuzivikela wokwakha amasistimu kagesi, iziteshi ezingaphansi, imboni esindayo nezitshalo zikagesi.
Ekuphetheni
Ama-MCCB angama-breaker circuit athembekile, asebenzayo futhi aphephile adlala indima ebalulekile ezinhlelweni zikagesi.Banikeza isivikelo esidingekayo semishini, izintambo kanye nabasebenzi ngokumelene nezingozi nomonakalo obangelwa ama-overcurrents nama-short circuits.Izilungiselelo zohambo oluthuthukisiwe lwe-MCCB, ukuvikelwa kukazibuthe okushisayo, idizayini ehlangene, izici zokuqapha, ukuqina nokuguquguquka kuyenza ibe inketho ekahle kunoma iyiphi isistimu kagesi.Ukuze uqinisekise ukusebenza kukagesi okuthembekile nokuphephile, shintshela kuma-MCCB futhi ujabulele izinzuzo ezinikezayo.
