Indlela i-MCB esebenza ngayo

Namuhla, sizobheka kabanzi ukusebenza okuyinkimbinkimbi kweama-circuit breaker amancane (I-MCB) futhi ufunde ukuthi zidlala indima ebalulekile ekugcineni amasekethe nemishini kuphephile. Ama-MCB angamadivayisi amancane avikela amasekethe kumasekethe angaphezu kwamandla kagesi kanye namasekethe amafushane. Aklanyelwe ukuvikela imigqa nemishini ekulimaleni okungenzeka ngokuphazamisa ukuhamba kukagesi uma kudlula amazinga aphephile. Kulesi sihloko, sizogxila ezimisweni ezimbili ezibalulekile zokuvikela ngaphakathi kwama-miniature circuit breakers: ukuvikelwa kokulayisha ngokweqile kanye nokuvikelwa kwamasekethe amafushane, futhi sihlole ukuthi lezi zimiso zisebenza kanjani ndawonye ukuze kugcinwe ukusebenza okuphephile nokusebenza kahle kwezinhlelo zikagesi.

Okokuqala, ake siqonde isimiso sokuvikela ukulayisha ngokweqile. Umsebenzi oyinhloko wokuvikela ukulayisha ngokweqile ukuvimbela ugesi osesekethe ukuthi ungadluli umthamo wawo olinganiselwe. Uma ugesi udlula isilinganiso, kungabangela izintambo nemishini ukuthi kushise ngokweqile, kudale ingozi enkulu yomlilo. Isimiso sokuvikela ukulayisha ngokweqile kuma-MCB sisekelwe emiphumeleni yokushisa. Lapho ugesi osesekethe udlula inani elibekiwe, ingxenye ye-bimetallic yento yokushisa esesekheni elincane le-circuit breaker ishiswa ugesi, okwenza izinga lokushisa layo likhuphuke. Uma izinga lokushisa selifinyelele ezingeni elibucayi, i-thermal element iyashintshashintsha, okwenza i-bimetal igobe phezulu, isunduze i-lever ukuvula i-latch ekhiyiwe. Lesi senzo sibangela ukuthi i-MCB ikhubeke, inqume ngempumelelo isekethe futhi ivimbele ugesi owengeziwe ukuthi ungagelezi phambili.

Ukuqhubekela esimisweni sesibili sokuvikela ukhiye, ukuvikelwa kwesekethe emfushane kudlala indima ebalulekile ekutholeni nasekunciphiseni ukukhuphuka kwamandla kagesi okungazelelwe. Isekethe emfushane yenzeka lapho amandla kagesi esesekethe ekhuphuka ngokuzumayo efinyelela emazingeni aphezulu kakhulu, ngokuvamile ngenxa yephutha noma isekethe emfushane phakathi kwezintambo. Lokhu kubeka ingozi enkulu kokubili imishini kanye nabasebenzi. I-MCB ifakwe iyunithi yokuhamba kagesi ekwazi kahle ukubona ukwanda okusheshayo kwamandla kagesi. Lapho kutholwa isekethe emfushane, ukukhishwa kwamandla kagesi kudala amandla aqinile okumunca adonsela i-ejector futhi abangele ukuthi i-latch ekhiyiwe ivuleke. Inqamula ngokushesha ukunikezwa kwamandla kagesi ukuze ivimbele amandla amakhulu ukuthi angadluli, ivikele ngempumelelo amasekethe kanye nemishini ekulimaleni okungenzeka.

Ngamafuphi, izimiso ezimbili zokuvikela zokuvikela ngokweqile kanye nokuvikela i-short-circuit kusiza ukugcina ukusebenza okuphephile nokusebenzayo kwamasekethe nemishini. Ama-MCB ayizingxenye ezibalulekile zezinhlelo zikagesi futhi aklanyelwe ukuqinisekisa ukusebenza kahle kwengqalasizinda kagesi ngenkathi kunciphisa izingozi ezihambisana ne-overcurrent kanye ne-short circuits. Ngomklamo wayo omncane kanye nezindlela zokuvikela ezinamandla, i-MCB inikeza ikhambi elithembekile nelisebenzayo lokuvikela izinhlelo zikagesi ezinhlobonhlobo zezicelo, kusukela ezindaweni zokuhlala kuya ezakhiweni zezimboni. Ngokuqonda ukusebenza okuyinkimbinkimbi kwama-MCB kanye nendima yawo ebalulekile ekuvikeleni amasekethe, singaqinisekisa ukuphepha nokuphila isikhathi eside kwengqalasizinda yethu kagesi.

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.
