Umsuka wejika lohambo
Umqondo wejika lohambo wavela emhlabeni we-IEC futhi usetshenziselwa ukuhlukanisa ama-micro-circuit breaker (B, C, D, K kanye no-Z) kusukela kumazinga e-IEC.Izinga lichaza imikhawulo ephansi nephezulu yohambo, kodwa abakhiqizi banokuguquguquka kokunquma ukucaciswa okunembayo ngaphakathi kwale mikhawuko okungadala ukuthi imikhiqizo yabo ihambe.Imidwebo yohambo ibonisa izindawo zokubekezelela lapho umkhiqizi angasetha izindawo zohambo ze-breaker breaker yayo.
Ijika lohambo lwe-circuit breaker
Izici nokusetshenziswa kwejika ngalinye, kusukela kokuzwela kakhulu kuye kokuzwela kancane, yilezi:
Z: Uhambo olukalwe izikhathi ezi-2 kuye kwezi-3 lwamanje, lufanele izinhlelo zokusebenza ezizwela kakhulu njengemishini ye-semiconductor
B: Uhambo oluyizikhathi ezi-3 kuye kwezi-5 olukalwe lwamanje
C: Uhambo olukalwe izikhathi ezi-5 kuye kweziyi-10, olufanele ukugijima okuphakathi nendawo
I-K: Uhambo olukalwe izikhathi eziyi-10 kuye kweziyi-14, lufanele imithwalo ene-inrush yamanje, esetshenziselwa ikakhulukazi izinjini kanye nama-transformer.
D: Uhambo oluyizikhathi eziyi-10 kuye kwezingama-20 olukalwe lwamanje, olufanele ukuqalisa okuphezulu kwamanje
Ukubuyekeza ishadi elithi “Ukuqhathaniswa kwawo wonke amajika e-IEC Trip”, ungabona ukuthi imisinga ephezulu icupha uhambo olusheshayo.
Ikhono lokumelana nomfutho wamanje liwukucatshangelwa okubalulekile ekukhetheni amajika ohambo.Imithwalo ethile, ikakhulukazi ama-motor nama-transformer, ihlangabezana nezinguquko zesikhashana kumanje, ezaziwa ngokuthi i-impulse current, lapho abathintwayo bevaliwe.Amadivayisi okuvikela asheshayo, njengamajika e-b-trip, angabona lokhu kutheleka njengokwehluleka futhi avule isekethe.Kulezi zinhlobo zemithwalo, amajika ohambo anamaphoyinti ohambo kazibuthe aphezulu (D noma K) "angadlula" ekuthelelekeni kwamanje kwamanje, avikele isifunda ohambweni lwamanga.
