Ama-circuit breaker enziwa ngezilinganiso zamandla kagesi ezahlukahlukene, kusukela kumadivayisi avikela ama-low-current circuits noma izinto zasendlini ngazinye, kuya kuma-switchgear aklanyelwe ukuvikela ama-high-voltage circuits ondla idolobha lonke.
I-Liperyenza i-Miniature circuit breaker (MCB) - i-current rated efika ku-63 A, evame ukusetshenziswa ekukhanyeni kwezindlu, kwezentengiselwano, nasezimbonini.
Ama-MCB awavami ukubhujiswa uma kune-over-current ngakho angasetshenziswa kabusha. Alula kakhulu futhi ukuwasebenzisa, anikeza lula 'kokuvula/ukuvala' ukuze kuhlukaniswe isekethe futhi njengoba umqhubi egcinwe ngaphakathi kwebhokisi lepulasitiki, aphephile kakhulu ukuwasebenzisa nokusebenza.
I-MCB ineizici ezintathu eziyinhloko, ama-Ampere, ama-Kilo Ampere kanye ne-Tripping Curve
Isilinganiso Samanje Sokulayisha Okungaphezu Komthwalo - Ama-Ampere (A)
Ukulayisha ngokweqile kwenzeka lapho izinto eziningi zikagesi zifakwa kwisekethe eyodwa futhi zidonsa amandla kagesi amaningi kunalawo isekethe nekhebula eziklanyelwe ukuwathatha. Lokhu kungenzeka ekhishini, isibonelo lapho ikettle, umshini wokuwasha izitsha, isitofu sikagesi, i-microwave kanye ne-blender konke kusetshenziswa ngesikhathi esisodwa. I-MCB kulesi sekethe inciphisa amandla ngaleyo ndlela ivimbela ukushisa ngokweqile kanye nomlilo kwikhebula kanye nama-terminal.
Ezinye izindinganiso:
Ama-amp ayi-6- izifunda zokukhanyisa ezijwayelekile
I-Amp eyi-10- izifunda zokukhanyisa ezinkulu
Ama-amp angu-16 kanye nama-amp angu-20- Ama-heater nama-boiler okucwilisa
Ama-amp angu-32- Indandatho Yokugcina. Igama lobuchwepheshe lesekethe yakho yamandla noma amasokhethi. Isibonelo, indlu enamakamelo okulala amabili ingaba nezisekethe zamandla ezingu-2 x 32A ukuze ihlukanise izisekethe eziphezulu nezingezansi. Izindlu ezinkulu zingaba nanoma yiliphi inani lezisekethe ezingu-32 A.
40 Amp- Izitofu zikagesi / ama-hob kagesi / amashawa amancane
Ama-amp angu-50- Amashawa kagesi angu-10kw / Amabhavu ashisayo.
Ama-amp angu-63- indlu yonke
Ama-Liper Breaker amboza ububanzi obusukela ku-1A kuya ku-63A
Isilinganiso Sesiyingi Esifushane - Ama-Kilo Amperes (kA)
I-Short Circuit ingumphumela wephutha endaweni ethile kusekethe kagesi noma kumshini wokusebenza futhi ingaba yingozi kakhulu kunokugcwala ngokweqile.
Ama-MCB asetshenziswa kuukufakwa kwasekhayangokuvamile zilinganiswa ku-6kAnoma ama-amps angu-6000. Ubudlelwano phakathi kwe-voltage evamile (240V) kanye nezilinganiso zamandla ezisetshenziswa zasekhaya ezijwayelekile busho ukuthi ugesi ongaphezu kwamandla okubangelwa yi-short circuit akufanele udlule ama-amps angu-6000. Kodwa-ke, kuizimo zezentengiselwano nezezimboni, uma usebenzisa i-415V kanye nemishini emikhulu, kuyadingeka ukusebenzisa10kAama-MCB alinganiswe.
Ijika Elikhubekayo
'I-Tripping Curve' ye-MCB ivumela umhlaba wangempela futhi ngezinye izikhathi okudingekayo ngokuphelele, ukwanda kwamandla. Isibonelo, ezindaweni zezentengiselwano, imishini emikhulu ivame ukudinga ukwanda kwamandla okuqala ngaphezu kwamandla ayo ajwayelekile okusebenza ukuze inqobe ukungabi namandla kwama-motor amakhulu. Lokhu kunyuka okufushane okuhlala imizuzwana embalwa, kuvunyelwe yi-MCB njengoba kuphephile ngesikhathi esifushane kakhulu.
BanguIzinhlobo ezintathu eziyinhloko ze-Curveokuvumela ukwanda kwamandla ezindaweni ezahlukene zikagesi:
Ama-MCB ohlobo Bzisetshenziswa ku-ukuvikelwa kwesekethe yasekhayalapho kungekho sidingo semvume yokwenyuka. Noma yikuphi ukwenyuka okukhulu endaweni yasekhaya kungenzeka kube umphumela wephutha, ngakho-ke inani lamandla angaphezu kwamandla avunyelwe lincane kakhulu.
Ama-MCB ohlobo Cukuhamba phakathi kwamanje omthwalo ogcwele izikhathi ezi-5 nezi-10 futhi kusetshenziswa kuizindawo zezentengiselwano nezilula zezimboniokungaba nezisekelo ezinkulu zokukhanyisa ezikhanyayo, ama-transformer kanye nemishini ye-IT efana namaseva, ama-PC kanye namaphrinta.
Ama-MCB ohlobo Dzisetshenziswa ku-izikhungo zezimboni ezisindayonjengezimboni ezisebenzisa ama-winding motor amakhulu, imishini ye-X-ray noma ama-compressor.
Zonke izinhlobo ezintathu zama-MCB zinikeza isivikelo sokukhubeka ngaphakathi kwengxenye yeshumi yomzuzwana. Okusho ukuthi, uma umthwalo omningi kanye nesikhathi sesidlulile, i-MCB iyakhubeka ngaphakathi kwemizuzwana engu-0.1.
Ngakho-ke, i-Liper ihlangabezana nazo zonke izidingo zakho.
