Amasekhethi enziwe ngezilinganiso zamanje ezihlukene, kusukela kumadivayisi avikela amasekhethi amanje aphansi noma izinto zikagesi zasendlini ngazinye, kuya kumshini wokushintshashintsha oklanyelwe ukuvikela amasekhethi anamandla kagesi aphezulu aphakela idolobha lonke.
Liperyenza i-Miniature circuit breaker (MCB) - ikalwe okwamanje kuze kufike ku-63 A, evame ukusetshenziswa ezindaweni zokuhlala, ezohwebo, izibani zezimboni.
Ama-MCB awavamisile ukubhujiswa ngesikhathi eseqile ngakho angasetshenziswa kabusha. Futhi kulula kakhulu ukuzisebenzisa, ezinikeza lula 'ukuvula/ukucisha ukushintsha' ukuze kuhlukaniswe isekethe futhi njengoba ikhondakta ifakwe ngaphakathi kwebhokisi lepulasitiki, kuphephe kakhulu ukuzisebenzisa nokusebenza.
I-MCB inakhoizici ezintathu eziyinhloko, i-Amperes, i-Kilo Amperes kanye ne-Tripping Curve
Isilinganiso Samanje Sokulayisha Okungaphezulu - Ama-Amperes (A)
Ukugcwala ngokweqile kwenzeka lapho izinto zikagesi eziningi kakhulu zifakwa kusekethe eyodwa futhi zidweba amandla kagesi amaningi kunaleyo sekethi nekhebula okuklanyelwe ukuthatha. Lokhu kungenzeka ekhishini, isibonelo lapho igedlela, umshini wokugeza izitsha, ihobhu kagesi, i-microwave ne-blender konke kusetshenziswa kanyekanye. I-MCB kule sekhethi inqamula amandla ngaleyo ndlela ivimbele ukushisa nomlilo kukhebula namatheminali.
Amanye amazinga:
6 amp- izifunda zokukhanyisa ezijwayelekile
10 Amp- izifunda ezinkulu zokukhanyisa
16 Amp kanye 20 Amp- Ama-heaters kanye nama-boilers
32 Amp- Ring Final. Itemu lobuchwepheshe lesekhethi yakho yamandla noma amasokhethi. Indlu enamakamelo amabili ngokwesibonelo ingaba namasekhethi kagesi angu-2 x 32A ukuze ahlukanise amasokhethi aphansi phezulu naphansi. Izindawo zokuhlala ezinkulu zingaba nanoma iyiphi inombolo yamasekhethi angu-32 A.
40 Amp- Abapheki / izindawo zokushisa zikagesi / amashawa amancane
50 amp- 10kw Izihlambi zikagesi / amashubhu ashisayo.
63 amp- indlu yonke
Ama-Liper Breakers ahlanganisa ibanga ukusuka ku-1A kuye ku-63A
Isilinganiso Somjikelezo Omfushane - Kilo Amperes (kA)
I-Short Circuit ingumphumela wephutha endaweni ethile endaweni kagesi noma entweni futhi iyingozi kakhulu kunokulayisha ngokweqile.
Ama-MCB asetshenziswa kuukufakwa kwasekhayangokuvamile zilinganiselwe ku6kAnoma 6000 amps. Ubudlelwano phakathi kwe-voltage evamile (240V) kanye nezilinganiso zamandla kagesi ezijwayelekile zasekhaya zisho ukuthi ukudlula kwamandla okubangelwa ukujikeleza okufushane akufanele kudlule ama-amps angu-6000. Nokho, kuizimo zezentengiselwano nezimboni, lapho usebenzisa i-415V nemishini emikhulu, kuyadingeka ukuyisebenzisa10kAama-MCB alinganisiwe.
Ijika Elijikayo
I-'Tripping Curve' ye-MCB ivumela umhlaba wangempela futhi ngezinye izikhathi kudingekile ngokuphelele, ukwanda kwamandla. Isibonelo, izindawo zezohwebo zezihambi, imishini emikhulu ivamise ukudinga ukukhuphuka kwamandla okuqala angaphezu kwamandla azo ajwayelekile ukuze inqobe inertia yamamotho amakhulu. Lokhu kuhlinzwa okufushane okuthatha imizuzwana nje, kuvunyelwe yi-MCB njengoba kuphephile ngesikhathi esifushane kakhulu.
BanguIzinhlobo ezintathu ze-Curveokuvumela ukuhamba ezindaweni ezahlukene zikagesi:
Uhlobo B MCBszisetshenziswa kuukuvikelwa kwesifunda sasekhayalapho kunesidingo esincane semvume yokuhlinzwa. Noma yikuphi ukukhuphuka okukhulu endaweni yasekhaya kungenzeka kube umphumela wephutha, ngakho inani lamanje elivunyelwe lincane uma kuqhathaniswa.
Uhlobo C MCBsukuhamba phakathi kuka-5 no-10 izikhathi ezigcwele zokulayisha zamanje futhi zisetshenziswa kuizimboni zezentengiselwano nezilulaokungase kube namasekhethi okukhanyisa amakhulu e-fluorescent, ama-transformer kanye nemishini ye-IT efana namaseva, ama-PC namaphrinta.
Uhlobo D MCBszisetshenziswa kuizinsiza zezimboni ezinzimanjengamafekthri asebenzisa izinjini ezinkulu ezisongayo, imishini ye-X-ray noma ama-compressor.
Zontathu izinhlobo zama-MCB zihlinzeka ngokuvikeleka kokukhubeka phakathi kokukodwa kweshumi kwesekhondi. Okusho ukuthi, uma ukulayishwa kanye nesikhathi seqiwe, i-MCB ihamba phakathi kwamasekhondi angu-0.1.
Ngakho-ke, uLiper uhlala ehlangabezana nazo zonke izidingo zakho.
