Zithini iingxaki zee-air circuit breakers (ACB)?

1. Isixhobo sokuvala i-air circuit breaker siwile saza asakwazi ukuvala kwakhona:
Okokuqala, misela ukuba ingaba i-air circuit breaker ikhubekile na ngaphandle kwengozi. Ukukhubeka okungengongozi kuthetha ukuba ikhubekile ngaphandle kwempazamo ye-short circuit okanye i-overload. Zininzi izizathu zokuba kutheniiqhekeza lesekethe yomoyaAyikwazi ukuvala. Okokuqala, kuyimfuneko ukufumanisa ukuba uhambo lubangelwa yi-short circuit kunye nokugqithisa, okanye ukuba i-circuit breaker ngokwayo okanye i-control circuit inempazamo. Landela la manyathelo angezantsi ukuze ufumane unobangela wempazamo. Okokuqala, jonga ukuba i-primary circuit ineengcingo ezimnyama okanye ezitshileyo kunye nabantu abaqhagamshelana nabo, ivumba ukuba kukho ivumba elingaqhelekanga, kwaye ingaba kukho impazamo kwi-secondary control circuit efanelekileyo kwikhabhinethi ye-low voltage. Ukuba i-fault point ifunyenwe, inokusebenza ngokuqhelekileyo emva kokuba isusiwe; ukuba akukho ndawo icacileyo yempazamo ifunyenweyo, i-circuit breaker ivaliwe phantsi kweemeko ezingenamthwalo. Ukuba i-circuit breaker ikhubekile kwaye ayinakusetyenziswa, i-air circuit breaker ngokwayo inempazamo; Ukuba i-circuit breaker ivaliwe, akukho mpazamo kwi-circuit breaker ngokwayo. Emva koko ii-branch line faults zifunyanwa ngokulandelelana.
2. Ukusilela komlawuli okrelekrele we-Air circuit breaker:
Emva kokuba isilawuli esikrelekrele se-air circuit breaker singasebenzi, isiganeko sokuvala ngesandla, ukuvala ngombane, kunye nokungaphumeleli komsebenzi wokukhusela wezigaba ezintathu kunye neminye imisebenzi yokukhusela ngokubanzi kuya kwenzeka. Ukusilela kwesilawuli esikrelekrele ngokubanzi kubangelwa kukutsha ngenxa ye-voltage ephezulu. Ngokubanzi, abavelisi balandela imigangatho yesizwe efanelekileyo kwaye bayila i-voltage yokusebenza elinganisiweyo ukuya kwi-400V. Nangona kunjalo, ekusebenzeni ngokwenene, xa ukusetyenziswa kwamandla kwehla phakathi kobusuku, ukuba i-transformer ayilawulwa yi-voltage, i-voltage ihlala ifikelela kwi-420V nangaphezulu. Umthamo omkhulu wenza i-smart. Isilawuli sitshiswe ngenxa ye-voltage ephezulu. Enye ingxaki eqhelekileyo yesilawuli kukuba ukuba i-fault memory ayicocwanga ngexesha, nokuba i-power grid fault isusiwe, i-circuit breaker isaya kucinga ukuba i-power grid inempazamo kwaye i-manual okanye i-electrical circuit breaker aziyi kukwazi ukuvala i-circuit breaker. Ngeli xesha, ungenza kuphela ngokwesiqhelo ngokulandela imisebenzi ekwi-manual yemiyalelo, ukucoca i-fault memory uze uyiphinde uyibeke. Abantu abaqhelekileyo abayi kucinga ukuba kungenxa yokuba isango alikwazi ukuvala, kwaye badla ngokungafumani unobangela wempazamo, okanye bayayazi imbangela, kodwa ngenxa yokuba umsebenzi wokucoca unzima kakhulu, banokufumana kuphela iingcali zobungcali, nto leyo ebangela ukucima kombane okungeyomfuneko. Isisombululo kukuba abavelisi be-air circuit breaker bafanele baphuhlise abalawuli abanokumelana noxinzelelo olungcono olulula nolulula ngakumbi ukusebenza, kwaye kwangaxeshanye baqinise uqeqesho lobuchwephesha lwabaqhubi.
