Qonda incazelo kanye nendima ye-MCB kugesi (1)

Umbono wokuqala: Kuyini i-MCB

I-MCB, obeye aziwe njengoi-miniature circuit breaker, kuyinto encaneI-circuit breakerlokho kudlala indima ebalulekile ezinhlelweni zikagesi. Ngokungafani nama-fuse endabuko, ama-MCB angasetshenziswa kabusha, ahlinzeke ngokuvikelwa okuthuthukisiwe emaphutheni kagesi abangelwa ukugcwala ngokweqile kwesekethe noma ama-short circuit. Ama-Miniature circuit breaker aqinisekisa ukuphepha nokuthembeka kwamadivayisi kagesi ngokulawula ukushintsha kwesekethe ngesandla noma ngokuzenzakalelayo.

Umbono wesibili: Indlela i-MCB esebenza ngayo

Isimiso sokusebenza se-MCB sisekelwe endleleni yokubambezeleka kukagesi okushisa. Uma ugesi ugeleza nge-MCB, kukhiqizwa insimu kagesi okushisa. Uma ugesi ufinyelela inani elibekiwe kusengaphambili, i-MCB iyakhubeka ngokuzenzakalelayo futhi inqume isekethe. Ngaphezu kwalokho, izakhi zokushisa ku-MCB zibona izinguquko zokushisa. Uma izinga lokushisa lidlula inani elibekiwe kusengaphambili, i-MCB izokhubeka futhi, ivimbele isekethe ekushiseni ngokweqile.

Umbono Wesithathu: Izinhlobo Zama-Miniature Circuit Breakers

Ama-MCB atholakala kumamodeli ahlukahlukene ngokusekelwe kumandla awo alinganiselwe, njenge-6A, 32A, 64A, njll. Ahlukaniswa futhi ngokusekelwe enanini lama-pole anawo, kusukela kuma-unipolar, bipolar, kuya kuma-configuration ama-pole amathathu. Ngaphezu kwalokho, amandla okuphuka alinganiselwe ama-miniature circuit breakers nawo ahlukile, kufaka phakathi i-4KA, 6KA, 8KA, njll.

Umbono wesine: Izinzuzo ze-MCB

Ama-MCB anikeza izinzuzo eziningi ngaphezu kwama-fuse endabuko. Okokuqala, ama-miniature circuit breaker mancane, alula, futhi kulula ukuwafaka nokuwashintsha. Ukwakheka kwawo okufushane kwenza kube kuhle kakhulu ekufakweni kukagesi kwesimanje. Okwesibili, ama-miniature circuit breaker angasetshenziswa kabusha izikhathi eziningi, okwenza abe shibhile futhi abe wusizo. Ngokungafani nama-fuse, adinga ukushintshwa ngemva kokwehluleka ngakunye, ama-MCB angamane aqalwe kabusha, okusindisa isikhathi nezinsiza.

Ngaphezu kwalokho, i-MCB inikeza ukuphepha okuthuthukisiwe kanye nokuthembeka. Bangaphazamisa isekethe ngesandla noma ngokuzenzakalelayo uma kudingeka, bavimbele umonakalo ongaba khona noma izimo eziyingozi. Ngokuphendula okusheshayo, i-MCB iqinisekisa ukunqanyulwa okusheshayo kwesekethe, ivikele imishini kagesi ekulimaleni.
