⑴ Ulungelelwaniso lweumephuli wojikelezokunye ne-circuit breaker kufuneka ithathele ingqalelo ixabiso lesenzo sokukhulula ngokukhawuleza kwi-high-level circuit breaker, ekufuneka ibe mkhulu kunobuninzi obulindelekileyo be-short-circuit current ekupheleni kwe-outlet ye-low-level circuit breaker.Ukuba ixabiso langoku le-short-circuit yangoku alihlukanga kakhulu, i-breaker circuit ephezulu inokukhetha iyunithi yohambo kunye nokulibaziseka kwexesha elifutshane.
⑵ Xa i-short-circuit current inkulu okanye ilingana nexabiso lokumisela lokukhululwa kwangoko kwe-current-limiting circuit breaker, iya kuhamba phakathi kwee-millisecond ezimbalwa.Ngoko ke, akufanelekanga kwizixhobo zokukhusela ezisezantsi ukuba zisebenzise i-breaker circuit ukuphumeza iimfuno zokukhusela ezikhethiweyo.
(3) Ngomqhekezi wesiphaluka ngokulibaziseka okufutshane, xa umda wexesha lawo libekwe ekulibazisekeni okukhulu, ukwenza kunye nokuphulwa kwamandla kunciphisa.Ke ngoko, kwisekethe yokukhusela ekhethiweyo, qwalasela ukukhetha ukulibaziseka okufutshane kunye nokuphula umthamo we-breaker circuit ukuhlangabezana neemfuno.
⑷ Kufuneka kwakhona kuthathelwe ingqalelo into yokuba ukulibaziseka kwesekethe emfutshane kubuya uphawu lwesaphuli sesekethe esikwinqanaba eliphezulu kunye nesenzo sexesha lejika lesaphuli sesekethe esikwinqanaba elisezantsi akufuneki linqumle, kwaye ijika elilibaziseka okufutshane kunye nejika eliphawulwe ngoko nangoko. mayinganqumli.
⑸ Xa i-breaker circuit kunye ne-fuse isetyenziswe kunye, ukulungelelaniswa kwamanqanaba aphezulu nangaphantsi kufuneka kuthathelwe ingqalelo.I-ampere-yesibini i-curve ye-curve ye-circuit breaker kufuneka ifaniswe kunye ne-ampere-yesibini ye-curve ye-fuse, ukwenzela ukuba ube nokukhethwa kokukhusela kwimeko ye-short-circuit current.
⑹ Xa i-breaker circuit isetyenziselwa ukukhusela isiphaluka sokusabalalisa, i-breaker circuit kunye nesenzo sokulibaziseka kwexesha elide kufuneka sikhethwe.Xa i-single-phase grounding short circuit iyenzeka ekupheleni komgca, i-short circuit current ayikho ngaphantsi kwe-instantaneous or short delay overcurrent of the circuit breaker 1.5 times the set current of the trip unit.
