Ukuqonda iiMcb Circuit Breakers: Isikhokelo esipheleleyo
Kwihlabathi lobunjineli bombane kunye nokhuseleko, ii-miniature circuit breakers (ii-MCB) zidlala indima ebalulekileyo ekukhuseleni ii-electrical circuits kwi-overloads kunye ne-short circuits. Ezi zixhobo zibalulekile kwiinkqubo zombane zokuhlala kunye nezezorhwebo, zikhusela izixhobo kunye neentambo kumonakalo onokubakho obangelwa yi-overcurrent.
Yintoni iMcb circuit breaker?
I-MCB circuit breaker sisitshixo esizenzekelayo esiphazamisa ukuhamba kombane kwisekethe xa sibona imeko engaqhelekanga, efana nokugqithiswa kakhulu okanye i-short circuit. Ngokungafaniyo nee-fuse zemveli, ekufuneka zitshintshwe emva kokuba zivuthuzekile, ii-MCB circuit breakers zinokusetwa kwakhona emva kokuba zivuthuzekile, nto leyo eyenza zibe lukhetho olulula nolusebenzayo lokukhusela isekethe.
Isebenza njani iMcb circuit breaker?
Ukusebenza kwee-Mcb circuit breakers kusekelwe kwiindlela ezimbini eziphambili: ubushushu kunye nemagnethi.
1. Indlela yobushushu:Eli candelo liphendula kwiimeko zokugqithisa kakhulu. Xa umbane ohamba kwisekethe udlula umthamo olinganisiweyo we-circuit breaker, ubushushu obuveliswayo bubangela ukuba i-bimetallic strip engaphakathi kwi-circuit breaker igobe. Nje ukuba ukugoba kufikelele kwinqanaba elithile, i-bimetallic strip ibangela indlela yokwaphula umbane, ivale umbane.
2. Indlela yeMagnetic: Le ndlela yenzelwe ukuphendula kwiisekethe ezimfutshane. Xa kwenzeka isekethe emfutshane, umsinga unyuka ngokukhawuleza, uvelisa amandla emagnethi anamandla atsala i-lever, nto leyo ebangela ukuba i-circuit breaker ikhubeke phantse ngoko nangoko. Le mpendulo ikhawulezayo ibalulekile ekuthinteleni umonakalo kwizinto zombane kunye nokunciphisa umngcipheko womlilo.
Uhlobo lwe-Mcb circuit breaker
Ii-Mcb circuit breakers ziyafumaneka kwiintlobo ezahlukeneyo, nganye yenzelwe injongo ethile:
Uhlobo B: Kwizicelo zokuhlala, olu hlobo lwe-circuit breaker luhamba ngokuphindwe kathathu ukuya kahlanu kunombane olinganisiweyo. Lufanelekile kakhulu kwiisekethe ezinemithwalo yokumelana, njengokukhanyisa nokufudumeza.
Uhlobo C: Olu hlobo lwenzelwe ukusetyenziswa kwezorhwebo nemizi-mveliso, kunye nomsinga wokuhamba ophindwe ka-5 ukuya kwi-10 kunomsinga olinganisiweyo. Ifanelekile kwiisekethe ezinemithwalo yokungenisa, njengeemoto kunye neetransformer.
Uhlobo DOlu hlobo lusetyenziswa kwizicelo ezinee-currents ezikhawulezayo eziphezulu, ezifana nee-motors ezinkulu kunye nee-transformers. Ihamba ngokuphindwe ka-10 ukuya kuma-20 kune-current elinganisiweyo.
Iingenelo zokusebenzisa ii-Mcb circuit breakers
1. Ukhuseleko: Ii-Mcb circuit breakers zibonelela ngendlela ethembekileyo yokukhusela ii-circuits kwi-overloads kunye ne-short circuits, zinciphisa kakhulu umngcipheko wemililo yombane kunye nomonakalo wezixhobo.
2. Ukulungela izintoNgokungafaniyo neefusi ezifuna ukutshintshwa emva kokuvuthuza, ii-Mcb circuit breakers zinokusetwa kwakhona ngokulula, nto leyo elula ukuyisebenzisa.
3. Uyilo oluNcinci: Ii-MCB circuit breakers zincinci kwaye zincinci kunezixhobo zokukhusela ii-circuit zemveli, nto leyo evumela ukusetyenziswa kakuhle kwesithuba kwiiphaneli zombane.
4. Ixabiso eliphantsiNangona utyalo-mali lokuqala lunokuba phezulu kunee-fuse, ukonga kwexesha elide ngenxa yokunciphisa umonakalo wezixhobo kunye nokulula kokuseta kwakhona kwenza ii-Mcb circuit breakers zibe lukhetho olungabizi kakhulu.
Ukufakelwa kunye nokugcinwa
Ukufakelwa kwe-circuit breaker kufuneka kwenziwe rhoqo yingcali yombane eqeqeshiweyo ukuqinisekisa ukuthotyelwa kwemithetho yombane yendawo kunye nemigangatho yokhuseleko. Kukwacetyiswa nokuhlolwa rhoqo kokugcinwa kwe-circuit breakers ukuqinisekisa ukuba i-circuit breakers isebenza kakuhle kunye nokuchonga naziphi na iingxaki ezinokubakho ngaphambi kokuba zibe nkulu.
Yintoni umahluko phakathi kwe-MCB kunye ne-MCCB breakers?
Ii-MCB: Zisetyenziswa ngokubanzi kwizicelo zorhwebo nezoshishino ezine-voltage ephantsi, ngesiqhelo i-120V, i-240V okanye i-480Y VAC, kunye ne-1000 VDC. Ii-MCCB: Zingasetyenziselwa zombini izicelo ezine-voltage ephantsi kunye ne-high, kunye ne-ratings edla ngokufikelela kwi-600V okanye i-690V, kwaye ezinye iimodeli zinikwe i-voltage ephezulu.
Isishwankathelo
Ngamafutshane, ii-MCB circuit breakers zizinto ezibalulekileyo kwiinkqubo zombane zanamhlanje, zibonelela ngokhuseleko, lula, kunye nokusebenza kakuhle. Ukuqonda imigaqo yazo yokusebenza, iintlobo, kunye neenzuzo kunokunceda abanini bezindlu kunye namashishini ukuba benze izigqibo ezinolwazi malunga neemfuno zabo zokhuseleko lombane. Njengoko iteknoloji iqhubeka nokutshintsha, ii-MCB circuit breakers ziya kuqhubeka nokuba yintsika yokhuseleko lombane, ziqinisekisa ukuba amakhaya ethu kunye neendawo zethu zokusebenza zikhuselekile kwiingozi zombane.
