Uhlelo lokucisha i-arc ye-MCCB kanye nedivayisi yokuhamba

Ama-circuit breaker e-molded case (I-MCCB) ziyizingxenye ezibalulekile ezinhlelweni zikagesi, zihlinzeka ngokuvikelwa kwe-short circuit kanye ne-overcurrent. Esinye sezici ezibalulekile ezenza i-MCCB isebenze kahle kakhulu uhlelo lwayo lokucisha i-arc kanye nedivayisi yokukhubeka. Ndawonye, ​​lezi zingxenye ezimbili ziqinisekisa ukuphepha nokuthembeka kwezinhlelo zikagesi, okwenza i-MCCB ibe yindawo ekahle yezinhlelo ezahlukene.

Uhlelo lokucisha i-arc ku-MCCB luyisici esibalulekile ekuvimbeleni nasekucimeni ama-arcs akhiqizwa lapho ama-circuit breaker ephazamisa ukuhamba kukagesi. Umsebenzi wesicisha-mlilo se-arc ukukhawulela nokuhlukanisa i-arc, ngaleyo ndlela uyicime. Lokhu kufezwa ngokusebenzisa igumbi lokucisha i-arc elivalelwe ebhokisini elinamandla amakhulu lokufaka ugesi, eliqukethe ama-grid amaningi okucisha i-arc. Lawa ma-grid adlala indima ebalulekile ekushiseni i-arc kanye nasekucimeni i-arc yemikhiqizo kagesi ene-voltage ephansi.

Uma ukuxhumana kuhlukana ngenxa yokuphazamiseka, ugesi ogeleza endaweni ene-ionized yokuxhumana udala insimu yamagnetic ezungeze i-arc kanye nesicisha-mlilo se-arc. Imigqa yamagnetic field ishayela i-arc epuletini lensimbi, lapho isuswa khona i-ion futhi ihlukaniswe, ngaleyo ndlela iyipholise. Le ndlela entsha iqinisekisa ukuthi i-arc icinywa ngempumelelo, ngaleyo ndlela ivikele izinhlelo zikagesi emonakalweni ongaba khona obangelwa yi-arcing.

Ngaphezu kohlelo lokucisha i-arc, idivayisi yokukhubeka ku-molded case circuit breaker nayo ibalulekile ukuqinisekisa ukuphepha nokuthembeka okuphelele kohlelo lukagesi. Idivayisi yokukhubeka isebenza njengobuchopho be-circuit breaker, ikhubeka indlela yokusebenza uma kwenzeka i-short circuit noma i-overcurrent eqhubekayo. Ama-molded case circuit breakers avamile asebenzisa amadivayisi okukhubeka e-electromechanical aklanyelwe ukuhlinzeka ngokuvikelwa okunembile nokuthembekile emaphutheni ahlukahlukene kagesi.

Ngokuthuthuka kobuchwepheshe, amadivayisi okukhubeka kagesi manje asetshenziswa kuma-circuit breaker akhiwe ngendlela ebumbene ukuze ahlinzeke ngemisebenzi yokuvikela nokuqapha ethuthukisiwe kakhulu. Lawa madivayisi okukhubeka kagesi athuthukisa ukusebenza kwe-MCCB iyonke, ehlinzeka ngokuvikelwa okuphezulu ekushiseni ngokweqile, ama-short circuit kanye namaphutha omhlaba ajikelezayo. Ukusetshenziswa kwamadivayisi okukhubeka kagesi kuqinisekisa ukuthi i-MCCB ingabhekana nezinhlelo zokusebenza ezahlukahlukene futhi ihlinzeke ngokuvikelwa okuthembekile kohlelo lukagesi.

Ukuhlanganiswa kohlelo lokucisha i-arc kanye nedivayisi yokukhubeka kwenza i-MCCB ibe yisinqumo esithembeke kakhulu nesisebenza kahle sokuvikela izinhlelo zikagesi. Uhlelo lokucisha i-arc luvimbela futhi lucime ngempumelelo ama-arcs, kuyilapho idivayisi yokukhubeka iqinisekisa ukuthi i-circuit breaker iphendula ngokushesha nangokunembile emaphutheni kagesi. Le ndlela yokuvikela ephelele yenza i-MCCB ifanelekele izinhlelo ezahlukahlukene, kufaka phakathi izindawo zezimboni, zezentengiselwano kanye nezindawo zokuhlala.

Ngamafuphi, uhlelo lokucisha i-arc kanye nedivayisi yokukhubeka ku-circuit breaker yekesi ebunjiwe idlala indima ebalulekile ekuqinisekiseni ukuphepha nokuthembeka kohlelo lukagesi. Izinhlelo zokucisha i-arc zivimbela futhi zicime ngempumelelo ama-arcs, zivikela izinhlelo zikagesi ekulimaleni okungenzeka. Ngesikhathi esifanayo, idivayisi yokukhubeka isebenza njengesikhungo sokulawula se-circuit breaker, inikeza ukuvikelwa okunembile nokuthembekile emaphutheni ahlukahlukene kagesi. Ngezici ezithuthukisiwe kanye nezindlela zokuvikela eziphelele, i-MCCB ilungele izinhlelo ezahlukahlukene, okwenza kube ukukhetha kokuqala kwezidingo zokuvikela kagesi.

I-Mutai Group iqoqe iminyaka engaphezu kweyishumi yesipiliyoni sokukhiqiza nokuthengisa e-USI-circuit breaker, oxhumana naye, amandla aphindwe kabiliinkinobho yokudlulisa okuzenzakalelayokanye nezinkambu ezihlobene. Silangazelela ithuba lokusebenza nawe.
