Ijika Elihambayo le-MCB

Ama-circuit breaker amancane (I-MCB) zidlala indima ebalulekile ekuvikeleni amasekethe nemishini. Lawa ma-miniature circuit breaker aklanyelwe ukuphazamisa ngokuzenzakalelayo ukuhamba kukagesi lapho kutholakala iphutha, ukuvimbela umonakalo ongaba khona ohlelweni nokuqinisekisa ukuphepha kwabasebenzi. Isici esibalulekile se-MCB uhlobo lwe-trip curve, olunquma isikhathi sokuphendula kanye nesilinganiso samanje se-circuit breaker lapho ikhubeka. Ukuqonda izinhlobo ezahlukene zama-trip curve kubalulekile ekukhetheni i-MCB efanele yohlelo oluthile.

Ijika lokugoba le-circuit breaker encane libhekisela ebuhlotsheni obuphakathi komshini wokugoba we-magnetic kanye nomshini olinganiselwe. Kunezinhlobo ezahlukene zamajika okugoba atholakalayo, ngalinye lifanele izinhlobo ezahlukene zemithwalo kanye nezinhlelo zokusebenza. Izinhlobo zamajika okugoba ezivame kakhulu zama-MCB zifaka phakathi Uhlobo A, Uhlobo B, Uhlobo C kanye nohlobo D. Uhlobo ngalunye lunezici ezithile futhi lufanele izimo ezahlukene, kusukela ekuvikeleni amasekethe kagesi e-semiconductor kuya ezindaweni zokuqala umthwalo osindayo.

Ijika lokugoba lohlobo A libonakala ngogesi wokugoba ongama-magnetic ongu-(2-3) In. Lifanele ukuvikela amasekethe kagesi e-semiconductor, amasekethe okulinganisa ama-transformer anamandla aphansi, noma izinhlelo ezinemigqa emide kanye nemisinga emincane. Ama-MCB ohlobo A aklanyelwe ukunikeza impendulo esheshayo kumaphutha aphansi, okwenza afaneleke kakhulu emishinini kagesi ebucayi kanye namasekethe adinga ukuvikelwa okunembile.

Ugesi ogoqayo we-type B tripping current ungama-(3-5) In. Lawa ma-MCB afanelekela imithwalo yokumelana kuphela kanye nezifunda zokukhanyisa eziphansi. Avame ukusetshenziswa ezinhlelweni zokusabalalisa amandla ekhaya, izinto zasendlini kanye nokuvikelwa kokuphepha komuntu siqu. Ama-MCB ohlobo B ahlinzeka ngokuvikelwa okusebenzayo kwezinhlelo ezahlukene zokuhlala nezebhizinisi.

Ugesi we-magnetic tripping we-Type C tripping curve ungama-(5-10) In. Lawa ma-MCB afanelekela imithwalo yokungenisa kanye nezisekelo zokukhanyisa ezibucayi kakhulu. Avame ukusetshenziswa ukuvikela imigqa yokusabalalisa kanye nezisekelo zokukhanyisa ezinezisekelo zokuhambisa eziphezulu. Ama-MCB ohlobo C aguquguqukayo futhi afanele ukusetshenziswa ezimbonini ezahlukahlukene lapho kudingeka khona ukuvikelwa okunembile kwemithwalo yokungenisa.

Ijika lokugoba lohlobo D libonakala ngogesi wokugoba ongama-magnetic ongu-(10-20) In. Lawa ma-MCB afaneleka ezinhlelweni ezinemithwalo enamandla kakhulu kanye nemisinga emikhulu yokungena. Avame ukusetshenziselwa ukuvikela imishini enemisinga ephezulu yokungena, njenge-transformers nama-valve e-solenoid. Ama-MCB ohlobo D aklanyelwe ukumelana nemithwalo esindayo futhi anikeze isivikelo esithembekile ezindaweni zezimboni.

Ngamafuphi, ukuqonda ama-tripping curves ezinhlobo ezahlukene zama-miniature circuit breakers kubalulekile ekukhetheni i-MCB efanele yohlelo oluthile. Kungakhathaliseki ukuthi ivikela ama-electronic circuits abucayi noma imishini yezimboni esindayo, ama-MCB anohlobo olufanele lwe-trip curve abalulekile ekuqinisekiseni ukuphepha nokuthembeka kwezinhlelo zikagesi. Ngamakhono awo ahlukahlukene, ama-MCB ahlala eyingxenye ebalulekile yokuphepha kukagesi nokuvikelwa ezimbonini ezahlukene.

I-Mutai Group iqoqe iminyaka engaphezu kweyishumi yesipiliyoni sokukhiqiza nokuthengisa e-USama-circuit breaker, ama-contactor, amandla aphindwe kabiliukushintsha okuzenzakalelayo kokudlulisa (I-ATS) kanye nezinkambu ezihlobene. Silangazelela ithuba lokusebenza nawe.
