Ukuhlukaniswa okuyisisekelo kakhulu kwama-circuit breakers-ACB MCCB MCB

Ama-Circuit breakers, eziwela ezigabeni ezintathu ezibanzi.

Uhlobo lokuqala lubizwa ngokuthii-air circuit breakeror i-air-insulated circuit breaker.Uphawu lwe-breaker Frame isI-ACB, njengoba igama elithi Umoya liyiSiyingi kanye negama elithi Umbhidlizi liwuMaphumulo.

Uhlobo lwesibili, olubizwai-case circuit breaker elibunjiwe, ngiI-MCCB;
Uhlobo lwesithathu yiloi-miniature circuit breaker, ophawu lwakheI-MCB.

Ibanga lamanje elilinganiselwe leI-ACB isuka ku-1250A iye ku-6300A, ububanzi obulinganiselwe obuphezulu;Ibanga lamanje elilinganiselwe leI-MCCB isuka ku-10A iye ku-1600A, enobubanzi bamanje obulinganiselwe phakathi nendawo.I-MCB inobubanzi obuncane bokulinganisa bamanje, ukusuka ku-6A ukuya ku-63A, kodwa iyinsika yama-breaker circuit asekhaya.
Akunandaba ukuthi hlobo luni, ukwahlukanisa phakathi koxhumana nabo abangaphakathi kwesiphakeli sesekethe kuncike emoyeni, okuyisizathu futhi esenza i-MCB yaziwa ngokuthi isishintshi somoya.
Njengoba i-insulation phakathi koxhumana nabo ngaphakathi kwe-circuit breaker incike emoyeni, kuyadingeka ukuthi sixoxe ngezici zokuqhekeka komoya, kanye nolwazi oluthile oluyisisekelo lwe-arc.

2. Mayelana ne-arc

Sibona i-arc njengefu legesi eshisayo.Ngaphakathi kwe-arc, emazingeni okushisa angaphezu kuka-3 000 degrees, ama-electron aphuma kuma-athomu akhe ama-ion angalungile, alahleka ukuze ama-athomu omoya abe yi-plasma yonke, ingxube yama-electron kanye negesi ye-ionic enhle.

3. Ibanga lokuvula le-breaker circuit

I-Frame circuit breaker i-ACB, ibanga elifushane kakhulu phakathi kothintana naye onyakazayo nothintwayo omile libizwa ngebanga elivulekile.
Ibanga lokuvula lisetshenziselwa ukuqinisekisa ukuthi umoya phakathi koxhumana nabo abavulekile awuphazamisi ugesi.
