Uyazi Yini Ama-Circuit Breakers?

Ayini ama-Circuit Breakers?

Iswishi kagesi eklanyelwe ukugada isekethe kagesi ukuthi ingalinyazwa okubangelwa ukulayisha ngokweqile kwamanje/ukulayisha ngokweqile noma isifunda esifushane saziwa ngokuthi i-circuit breaker.Umsebenzi wayo oyinhloko ukuphazamisa i-ow yamanje ngemuva kokuthi ukudluliselwa kokuvikela kubone inkinga.

Umsebenzi Wokushintsha Kwe-Circuit Breaker.

Umsebenzi we-circuit breaker ngokuba idivayisi yokuphepha ngaleyo ndlela uvimbele ukulimala kwezinjini kanye nezintambo lapho i-current egeleza kwisekethe kagesi idlula imikhawulo yokuklama kwayo.Lokhu ikwenza ngokususa i-current kusekethe uma kuvela isimo esingaphephile.

Asebenza kanjani ama-DC Circuit Breakers?

Njengoba igama labo liphakamisa, ama-circuit breaker e-Direct Current (DC) avikela izinto zikagesi ezisebenza ngamandla aqondile.Umehluko obalulekile phakathi kwamandla aqondile nashintshayo ukuthi amandla kagesi ku-DC ahlala njalo.Ngokuphambene, amandla kagesi ku-Alternating Current (AC) ajikeleza izikhathi ezimbalwa umzuzwana ngamunye.

Uyini Umsebenzi We-DC Circuit Breaker?

Izimiso ezifanayo zokuvikela ezishisayo nezikazibuthe ziyasebenza kuma-DC breaker njengoba enza kuma-AC circuit breaker:
Ukuvikela okushisayo kugibelisa i-DC circuit breaker lapho amandla kagesi edlula inani elilinganiselwe.Ukushisa kokuxhumana kwe-Bimetallic kwanda futhi kuhambe i-breaker circuit kule nqubo yokuvikela.Isivikelo esishisayo sisebenza ngokushesha ngoba i-current ikhiqiza ukushisa okwengeziwe ukuze kwandiswe futhi ivule uxhumano lukagesi njengoba lwamanje lukhulu.Isivikelo esishisayo sesiphakeli sesekethe se-DC sivikela amandla okulayisha ngokweqile angaphezulu kancane kunowamanje osebenzayo ojwayelekile.
Uma amaphutha anamandla akhona, ukuvikela kazibuthe kugibela isinqamuli sesifunda se-DC, futhi impendulo ihlala isheshayo.Njengama-circuit breaker e-AC, ama-circuit breaker e-DC anomthamo wokuphuka olinganiselwe omelela iphutha elibaluleke kakhulu lamanje elingaphazanyiswa.
Iqiniso lokuthi ukumiswa kwamanje kuhlale kuhambisana nama-circuit breaker e-DC kusho ukuthi i-circuit breaker kufanele ivule ukuxhumana kukagesi kude ukuze kuphazamise amandla akhona.Onogada kazibuthe be-DC circuit breaker ngokumelene namasekhethi amafushane namaphutha abanzi kakhulu kunokulayisha ngokweqile.

Izinhlobo ezintathu ze-Miniature Circuit Breaker:

Thayipha B (uhambo ngezikhathi ezi-3-5 ezilinganiselwe njengamanje).
Uhlobo C (uhambo oluyizikhathi ezi-5-10 olukalwe lwamanje).
Uhlobo D (uhambo oluyizikhathi eziyi-10-20 olukalwe lwamanje).
