Ama-Circuit Breaker: Ukuqonda Ukubaluleka Kwawo Ezinhlelweni Zikagesi

Emikhakheni yobunjiniyela kagesi kanye nokuphepha, igama elithi “circuit breaker” libaluleke kakhulu. I-circuit breaker iyiswishi kagesi ezenzakalelayo eyenzelwe ukuvikela amasekethe emonakalweni obangelwa ukugcwala ngokweqile noma amasekethe amafushane. Umsebenzi wayo oyinhloko ukuphazamisa ugesi lapho kutholakala iphutha, ngaleyo ndlela kuvinjelwe izingozi ezingaba khona njengemililo kagesi noma umonakalo wemishini. Lesi sihloko sizohlola izici ezahlukahlukene zamasekethe, okuhlanganisa izinhlobo zawo, imisebenzi, kanye nendima ebalulekile ayidlalayo ezinhlelweni zikagesi zanamuhla.

Ibizwa nangokuthini i-circuit breaker?

I-circuit breaker, eyaziwa nangokuthi i-magneto-thermal breaker, iyisici esibalulekile ekufakweni kukagesi kwanamuhla.

Imisebenzi Yama-Circuit Breakers

Umsebenzi oyinhloko we-circuit breaker uwukuba yidivayisi yokuphepha yokuqapha ugesi ku-circuit. Uma ugesi udlula umkhawulo ohleliwe, i-circuit breaker iyakhubeka, inqamule ugesi. Lesi senzo asivikeli nje kuphela izintambo nemishini exhunyiwe kodwa futhi siqinisekisa ukuphepha kwabantu abangase babanjwe ugesi.

Kunezimiso ezimbili eziyinhloko zokusebenza kwama-circuit breaker:ukushisafuthiamandla kazibutheAma-thermal circuit breaker asebenzisa imichilo ye-bimetallic; uma ugesi uphezulu kakhulu, ugesi we-bimetallic uyashisa futhi ugobe, okwenza i-circuit breaker ikhubeke. Ama-magnetic circuit breaker asebenzisa ama-electromagnet; uma ugesi udlula umkhawulo othile, i-electromagnet iyabandakanyeka, okubangela ukuba i-circuit breaker ikhubeke. Amanye ama-circuit breaker anamuhla ahlanganisa zombili izindlela zokuthuthukisa ukusebenza kokuvikela.

Izinhlobo ze-Circuit Breakers

Ama-circuit breaker eza ngezinhlobo eziningi, ngayinye yenzelwe izinhlelo zokusebenza ezithile kanye nezindawo ezithile. Izinhlobo ezivame kakhulu zifaka:

1. Ama-Miniature Circuit Breaker (ama-MCB):Ama-Miniature circuit breaker asetshenziswa kabanzi ezindaweni zokuhlala nezebhizinisi ukuvimbela ukugcwala ngokweqile kanye nama-short circuits. Mancane ngobukhulu futhi kulula ukuwafaka emabhokisini okusabalalisa.
2. I-Residual Current Breaker (RCCB):Le divayisi eyaziwa nangokuthi i-RCD, ivimbela ukushaqeka kukagesi ngokuthola ukungalingani kwamandla kagesi. Uma kwenzeka iphutha, njengomuntu othinta ucingo oluphilayo, i-RCCB izokhubeka, inqamule ugesi.
3. Ama-Molded Case Circuit Breaker (ama-MCCB): Lawa ma-circuit breaker asetshenziswa ezisetshenziswa ezimbonini futhi ayakwazi ukuphatha amaza aphezulu. Ama-MCCB ahlinzeka ngokuvikelwa kokudlula ngokweqile, ukujikeleza okufushane, kanye nokuvikela amaphutha omhlaba.
4. Ama-Air Circuit Breaker (ama-ACB): Ama-air circuit breaker avame ukusetshenziswa ezinhlotsheni ze-voltage ephezulu futhi aklanyelwe ukuphazamisa ugesi omkhulu. Avame ukutholakala eziteshini ezincane nasezindaweni ezinkulu zezimboni.
5. Ama-Hydraulic Magnetic Circuit Breakers:Lawa ma-circuit breaker asebenzisa izindlela ze-hydraulic zokukhubeka, enikeza ikhambi elithembekile lezinhlelo zokusebenza zamandla aphezulu.

Ukubaluleka kwama-circuit breakers

Ukubaluleka kwama-circuit breaker akunakubukelwa phansi. Ziyizingxenye ezibalulekile eziqinisekisa ukusebenza okuphephile nokuthembekile kwezinhlelo zikagesi. Ngokuvimbela ukugcwala ngokweqile kanye nama-short circuit breaker, ama-circuit breaker asiza ekunciphiseni ingozi yomlilo kagesi, umonakalo wemishini, kanye nokulimala komuntu. Ngaphezu kwalokho, uma kwenzeka iphutha, ama-circuit breaker angasheshe aqalwe kabusha, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwesistimu kagesi.

Ngaphezu kwemisebenzi yazo yokuvikela, ama-circuit breaker adlala indima ebalulekile ekuhambisaneni nemithetho kagesi kanye nezindinganiso. Izifunda eziningi zidinga ukuthi ama-circuit breaker afakwe ezakhiweni zokuhlala nezebhizinisi ukuqinisekisa ukuphepha nokuthembeka.

Kafushane

Ngamafuphi, ama-circuit breaker ayizinto ezibalulekile emkhakheni wobunjiniyela kagesi. Avikela ama-circuit ekugcwaleni ngokweqile kanye nama-short circuit, okwenza abe abalulekile ekugcineni ukuphepha kwezindawo zokuhlala nezimboni. Njengoba ubuchwepheshe buthuthuka, ama-circuit breaker ayaqhubeka nokukhula ukuze ahlinzeke ngamazinga aphezulu okuvikela nokusebenza kahle. Ukuqonda izinhlobo ezahlukene zama-circuit breaker kanye nemisebenzi yawo kubalulekile kunoma ubani osebenza emkhakheni kagesi, njengoba kuqinisekisa ukusebenza okuphephile nokusebenza kahle kwezinhlelo zikagesi. Kungakhathaliseki ukuthi kusemakhaya, emahhovisi, noma ezimbonini, ama-circuit breaker ahlala eyingxenye ebalulekile yengqalasizinda kagesi yesimanje.
