Iziphuli zesekethe zenziwe ngokwemilinganiselo eyahlukeneyo yamandla ombane, ukusuka kwizixhobo ezikhusela iisekethe zamandla ombane aphantsi okanye izixhobo zasekhaya, ukuya kwiiswitshi ezenzelwe ukukhusela iisekethe zamandla ombane aphezulu ezondla isixeko siphela.
I-Liperyenza i-Miniature circuit breaker (MCB) - i-current rated ukuya kuthi ga kwi-63 A, esetyenziswa rhoqo kwizibane zokuhlala, zorhwebo, nezemizi-mveliso.
Ii-MCB azidla ngokutshatyalaliswa xa kukho umbane omninzi ngoko ke zinokuphinda zisetyenziswe. Zikwalula kakhulu ukuzisebenzisa, nto leyo enika lula 'ukutshintsha/ukuvula' ukuze kubekwe i-circuit isolation kwaye ekubeni umqhubi egcinwe ngaphakathi kweplastiki, zikhuselekile kakhulu ukuzisebenzisa nokuzisebenzisa.
I-MCB inayoiimpawu ezintathu eziphambili, ii-Ampere, iiKilo Amperes kunye neTripping Curve
Uvavanyo lwangoku olugqithisileyo - ii-Ampere (A)
Umthwalo omninzi uyenzeka xa izixhobo ezininzi kakhulu zifakwa kwisekethe enye kwaye zitsala umbane omninzi kunalowo wesekethe kunye nentambo ezenzelwe ukuwuthatha. Oku kungenzeka ekhitshini, umzekelo xa iketile, isitya sokuhlamba izitya, isitovu sombane, i-microwave kunye ne-blender zonke zisetyenziswa ngaxeshanye. I-MCB kule sekethe inciphisa umbane ngaloo ndlela ithintela ubushushu obugqithisileyo kunye nomlilo kwikheyibhile nakwii-terminals.
Eminye imigangatho:
6 Amp- iisekethe zokukhanyisa eziqhelekileyo
I-10 Amp- iisekethe ezinkulu zokukhanyisa
Ii-Amp ezili-16 kunye nee-Amp ezingama-20- Izifudumezi kunye neebhoyila zokuntywilisela
32 Amp- Isiphelo seRing. Igama lobuchwephesha lesekethe yakho yamandla okanye iisokhethi. Umzekelo, indlu enamagumbi okulala amabini inokuba neesekethe zamandla ezi-2 x 32A ukuze zahlule iisokhethi eziphezulu nezisezantsi. Izindlu ezinkulu zinokuba nenani leesekethe ezingama-32 A.
40 Amp- Izipheki / iitovu zombane / iishawa ezincinci
50 Amp- Iishawa zombane ze-10kw / Iibhafu ezishushu.
63 Amp- indlu yonke
IiLiper Breakers zigubungela uluhlu oluqala kwi-1A ukuya kwi-63A
Uvavanyo lweSekethe eNcinci - iiKilo Amperes (kA)
I-Short Circuit sisiphumo sempazamo kwindawo ethile kwisekethe yombane okanye kwisixhobo kwaye inokuba yingozi kakhulu kunokugqithisela.
Ii-MCB ezisetyenziswa kwiukufakwa kwekhayazihlala zilinganiswa kwi6kAokanye ii-amps ezingama-6000. Ubudlelwane phakathi kwe-voltage eqhelekileyo (240V) kunye nokulinganiswa kwamandla ezixhobo zasekhaya kuthetha ukuba i-over-current ebangelwa yi-short circuit akufuneki idlule ii-amps ezingama-6000. Nangona kunjalo, kwiiimeko zorhwebo nezoshishino, xa usebenzisa i-415V kunye noomatshini abakhulu, kuyimfuneko ukuyisebenzisa10kAii-MCB ezilinganisiweyo.
Ijika elikhubekayo
'I-Tripping Curve' ye-MCB ivumela ihlabathi lokwenyani kwaye ngamanye amaxesha kuyimfuneko ngokupheleleyo, ukunyuka kwamandla. Umzekelo, kwiindawo zorhwebo, oomatshini abakhulu badla ngokufuna ukunyuka kwamandla okuqala ngaphezu komsinga wabo oqhelekileyo wokubaleka ukuze boyise ukungasebenzi kakuhle kweenjini ezinkulu. Oku kunyuka okufutshane kuthatha imizuzwana nje embalwa, kuvunyelwe yi-MCB kuba kukhuselekile ngexesha elifutshane kakhulu.
NaziIindidi ezintathu zeCurve ezisisisekoezivumela ukunyuka kwamandla kwiindawo ezahlukeneyo zombane:
Ii-MCB zohlobo Bzisetyenziswa kwiukhuseleko lwesekethe yasekhayaapho kungekho mfuneko ingako yemvume yokunyuka. Nakuphi na ukunyuka okukhulu kwindawo yasekhaya kusenokwenzeka ukuba kungenxa yempazamo, ngoko ke ubungakanani bombane ongaphezulu kombane ovumelekileyo buncinci kakhulu.
Ii-MCB zohlobo Cuhambo oluphakathi komthwalo opheleleyo ophindwe ka-5 ukuya ku-10 kwaye lusetyenziswa kwiiindawo zorhwebo nezilula zoshishinoezinokuba neesekethe ezinkulu zokukhanyisa ezikhanyayo, iitransformer kunye nezixhobo ze-IT ezifana neeseva, iiPC kunye neeprinta.
Ii-MCB zohlobo Dzisetyenziswa kwiizakhiwo zoshishino ezinzimanjengeefektri ezisebenzisa iimoto ezinkulu ezijikelezayo, oomatshini be-X-ray okanye iicompressor.
Zonke ezi ntlobo zintathu ze-MCB zibonelela ngokhuseleko lokukhubeka kwisithuba seshumi sesekhondi. Oko kukuthi, xa umthwalo omninzi kunye nexesha sele lidluliwe, i-MCB iyakhubeka kwisithuba semizuzwana eyi-0.1.
Ngoko ke, iLiper isoloko ihlangabezana nazo zonke iimfuno zakho.
