Yintoni i-6kA AC Miniature Circuit Breaker?
Isaphuli sesekethe esincinci, esiqhele ukubizwa ngokuba yi-MCB, sisixhobo sokutshintsha esikhuselayo esenzelwe ukukhupha ngokuzenzekelayo isekethe yombane xa iimeko zangoku ezingaqhelekanga zisenzeka. Ngokungafaniyo ne-fuse yesiko, i-MCB iqhele ukusetwa kwakhona emva kokuba isiphene sisusiwe, nto leyo eyenza kube lula ukusebenza ngokuphindaphindiweyo kunye nokugcinwa.
Igama elithile6kAibhekisela kwi-breaker's rated short-circuit breaking capacity phantsi kweemeko zovavanyo olusebenzayo. Ngamagama alula, i-6kA MCB yenzelwe ukuphazamisa ngokukhuselekileyo i-current short-circuit current ukuya kwi-6,000 amperes xa iimfuno ezichaziweyo zidibene.
Iimveliso ezithobela i-IEC/EN 60898-1 zihlala zichaza iiparamitha ezinje ngokureyithwa kwangoku, amandla ombane alinganisiweyo, amaza, ukophuka, kunye neempawu zokukhubeka ngoko nangoko. Iindidi zeMCB yoRhwebo zinokubonelela nge-6kA kwiireyithingi ezahlukeneyo zangoku kunye nolungelelwaniso lwepali.
I-6kA ayiyiyo i-current yokusebenza yesiqhelo ye-breaker. I-16A MCB, umzekelo, ijonge ukuthwala isantya sayo esilinganisiweyo phantsi kweemeko ezichaziweyo, ngelixa i-6kA figure ichaza amandla ayo okuphazamisa i-short-circuit. Ezi nkcukacha zimbini ziphendula imibuzo yobunjineli eyahlukileyo ngokupheleleyo.
Kutheni i-6kA yoKwaphulwa kweSakhono ibalulekile?
Iisekethe ezimfutshane zinokuvelisa imisinga ephezulu kakhulu ngexesha elifutshane kakhulu. Ukuba isixhobo sokukhusela asikwazi ukuphazamisa ngokukhuselekileyo i-fault current ekhoyo kwindawo yofakelo, iziphumo zingabandakanya umonakalo onzima wokudibanisa, ukushisa okugqithisileyo, ukungasebenzi kwezixhobo, okanye ukubethelwa kombane okuyingozi.
Ke ngoko, umthamo wokwaphuka akufuneki ukhethwe nje kuba i-6kA luphawu oluqhelekileyo olufumanekayo. I-current short-circuit current kwindawo yofakelo kufuneka ihlolwe, kwaye i-breaker ekhethiweyo kufuneka ibe nekhono lokuphazamiseka okwaneleyo kweso sistim.
| Ipharamitha | Ithetha ukuthini | Isizathu Sokuba Kubalulekile |
|---|---|---|
| 6kA | Ireyithwe umthamo wokophuka kwesekethi emfutshane | Imisela ukuba i-breaker inokuphazamisa inqanaba elichaziweyo lesiphoso-yangoku ngokukhuselekileyo |
| Ikalwe ngoku (kwi) | Ireyithingi eqhelekileyo yangoku ye-MCB | Kufuneka iququzelele umthamo womqhubi kunye nomthwalo olindelekileyo |

| Inani leePali | Inani lee-conductors ezitshintshiweyo/ezikhuselweyo | Kufuneka ifanise ubumbeko lwesekethe |
Iinkcukacha zomenzi zibonisa ukuba ii-MCB ze-6kA ziyafumaneka kuluhlu lwemilinganiselo yangoku kunye nokulungelelaniswa kombane, kubandakanywa ne-230V eqhelekileyo kunye ne-400V yeenkqubo zokusasazwa kwe-AC.
Ingaba i-AC Miniature ye-Circuit Breaker iyikhusela njani iSekethe?
I-MCB eqhelekileyo idibanisa iindlela zokukhusela ezishushu kunye nemagnethi. Le misebenzi mibini ijongana neengxaki ezahlukeneyo zombane.
- Ukhuseleko lobushushu:Umthwalo ogqithisileyo ozinzileyo ufudumeza i-bimetallic element. Xa iqondo lokushisa lifikelela kumda wokusebenza, indlela ikhupha kwaye ivule isiphaluka.
- Ukhuseleko lwemagnethi:Umsinga omfutshane omfutshane wenza impembelelo enamandla yamagnetic eyenza indlela yokuhamba ngokukhawuleza, ikhuphe isiphaluka ngokukhawuleza.
- Ukutshintsha ngesandla:I-MCB ngokuqhelekileyo ingatshintshwa ngesandla ukwenzela ukwahlulwa kwesekethe ngexesha lolondolozo okanye lofakelo.
Le ndibaniselwano yenza i-MCB ilungele iisekethe apho zombini ukulayisha ngaphezulu kwexesha elide kunye neempazamo zesekethe ezimfutshane ngequbuliso kufuneka ziqwalaselwe. Uluhlu lwemveliso ye-MCB yanamhlanje ludla ngokudibanisa ukukhutshwa kwe-thermal kunye nemagnethi kwaye inokubonelela ngeempawu ze-B, C, okanye D ngokuxhomekeke kumthwalo ocetywayo.
Zeziphi iiParameters zobuGcisa ekufuneka abathengi bazijonge?
Abathengi bahlala begxila kukalisho lwangoku kunye nexabiso ngelixa bejonge ezinye iiparamitha. Ukucaciswa kweprojekthi ethembekileyo, ezi mpawu zilandelayo kufuneka zihlolwe kunye.
| Inkcazo | Ingqwalaselo eqhelekileyo | Indawo yokujonga umthengi |

Imibuzo ebuzwa qho
I-6kA ibhekiselele kumthamo wokuqhawulwa kwesekethe emfutshane ereyithiweyo phantsi kweemeko zovavanyo ezisebenzayo. Imele i-6,000 amperes kwaye akufanele ibhidaniswe ne-MCB yesiqhelo yangoku.
Hayi. Ukufaneleka kuxhomekeke kumbane olindelekileyo wesekethe emfutshane, amandla ombane enkqubo, ireyithingi yangoku, uphawu lohambo, ulungelelwaniso lwepali, iimeko zofakelo, kunye nemigaqo esebenzayo. Impazamo ekhoyo yangoku kufuneka ihlolwe ngaphambi kokukhetha i-breaker.
Amanani amabini achaza iiparamitha ezahlukeneyo. I-6kA yireyithi yomthamo wokuqhawuka, ngelixa i-6A lixabiso langoku. I-breaker inokuba ne-6A elinganiselwe ngoku kunye ne-6kA yokuphulwa kwamandla.
Bachonga iimpawu ezahlukeneyo zokukhubeka ngoko nangoko. Ngaphantsi kwe-IEC 60898-1, i-B ngokuqhelekileyo idityaniswa malunga namaxesha angama-3-5 alinganiselwe ngoku, i-C malunga namaxesha angama-5-10, kunye ne-D malunga namaxesha angama-10-20.
IiMotor zinokuba nesiqalo esikhulu sangoku, ngoko ke iimpawu ze-C okanye ze-D zinokufaneleka ngokuxhomekeke kwimotor kunye nesekethe. Ukukhethwa kokugqibela kufuneka kuthathelwe ingqalelo ukuqala okwangoku, impazamo yangoku, i-cable impedance, kunye nokulungelelaniswa nezinye izixhobo zokukhusela.
Ayizenzekeli. Ukuba umbane olindelekileyo we-short-circuit current ugqithise umthamo we-breaker rated rated breaking, isixhobo se-6kA sisenokungafaneleki. I-breaker kufuneka ikhethwe ngokwenqanaba lesiphoso kunye neemfuno zofakelo olusebenzayo.
Abathengi kufuneka baqhele ukucela idatha eneenkcukacha, iinkcukacha zobugcisa, imizobo enobukhulu, imiyalelo yofakelo, uvavanyo olusebenzayo okanye amaxwebhu esiqinisekiso, kunye nemigangatho efanelekileyo yemveliso. Iimfuno ezingqamene neprojekthi zinokufuna amaxwebhu awongezelelweyo.
Ukuhambelana phakathi kweebhetshi zokuvelisa, ukulandelwa, amaxwebhu obugcisa, ukulawula umgangatho, amandla okuhambisa, kunye nenkxaso yobugcisa emva kokuthengisa kunokuchaphazela kakhulu iindleko ezipheleleyo kunye nokuthembeka kweprojekthi yombane ye-B2B.
Yakha isisombululo soKhuseleko lweSekethe esithembeke ngakumbi
Ukukhetha a6kA AC Miniature Circuit Breakerkufuneka iqale ngeemeko zombane zesicelo kuneleyibhile yemveliso yodwa. Ireyithingi yangoku, umthamo wokwaphuka, ijika lokuhamba, umbane, ulungelelwaniso lwepali, indawo yofakelo, kunye namaxwebhu obugcisa zonke zinegalelo kwisisombululo esithembekileyo sokhuseleko.
Ukuba ukhangela ii-MCBs zeeprojekthi zokuhambisa umbane, iipaneli zolawulo, izakhiwo zorhwebo, izicelo zokuhlala, okanye ukuhanjiswa kwehoseyile,IIIIShanghai DaDa Electric Co., Ltd.inokukunceda ukuba uvavanye imilinganiselo yemveliso efanelekileyo ngokweemfuno zeprojekthi yakho.
