Xa isoftware yenkqubo ingaphumeleli, amacandelo eempazamo eziqhelekileyo akhusela i-posture, kwaye i-breaker circuit isebenze ngokwenene impazamo eqhelekileyo ukugatya uhambo, i-breaker circuit ekufutshane ye-substation iya kukhusela uhambo ngokuhambelana ne-common fault components.Ukuba iimeko azivumeli, umjelo wokhuseleko unokusetyenziselwa ukwenza i-remote circuit breaker trip ngexesha elinye.Indlela yocingo ibizwa ngokuba yi-circuit breaker common fault protection.
Ngokuqhelekileyo, emva kokuhamba kwamacandelo akhoyo ngoku, amaqela ama-2 oxhumano olusebenzayo athathwe kwaye adibaniswe ngokulandelelana kunye nezixhumi zokukhusela i-posture yangaphandle, kwaye ke ukukhuselwa kwephutha eliqhelekileyo kuqhutyelwa kwindlela.
Wenza ntoni umaphuli wesekethe?
Izaphuli zesekethe zisetyenziswa ikakhulu kwiimotor, iziguquli zendawo enkulu kunye nezikhululo zokuhambisa ezihlala zikhupha imithwalo.I-breaker circuit inomsebenzi wokuphula umthwalo wengozi yokhuseleko, kwaye isebenzisana nokukhusela okuhlukahlukeneyo kwe-relay ukukhusela izixhobo zombane okanye iindlela.
I-breaker circuit isetyenziselwa ngokubanzi inxalenye ye-low-voltage lighting force drive, kwaye inokukhupha ngokuzenzekelayo isiphaluka;i-breaker circuit nayo inemisebenzi emininzi efana nomthwalo kunye nokukhusela impazamo yesiphaluka esifutshane, kodwa xa kukho ingxaki ngomthwalo ongezantsi, kufuneka igcinwe.umsebenzi, kwaye i-voltage yokuqhekeka ye-breaker circuit ayanelanga.
Namhlanje kukho i-breaker circuit breaker kunye nokukhusela, edibanisa imisebenzi ye-breaker circuit breaker kunye ne-high-voltage disconnector.I-breaker circuit breaker kunye nokukhusela inokusetyenziswa kwakhona njengokutshintsha komzimba womntu ophezulu we-voltage.Enyanisweni, ii-switch-high-voltage zokuhlukanisa ngokubanzi azikwazi ukusebenza kunye nomthwalo, kodwa abaphuli beesekethe banemisebenzi yokukhusela efana nephutha le-short-circuit, ukukhuselwa komthwalo, kunye nokukhuselwa kwe-voltage.
Ichaza umgaqo wokusebenza wabaphuli beesekethe ngokweenkcukacha
Uhlobo oluSisiseko: Isixhobo esilula sokukhusela isekethe yi-fuse.I-fuse yintambo nje encinci, ene-sheath ekhuselayo, ethi ke idibaniswe kwisekethe.Emva kokuba isiphaluka sivaliwe, yonke into yangoku kufuneka idlule kwi-fuse, kwaye i-current ye-fuse ifana nokukhoyo kwamanye amanqaku kwisiphaluka esifanayo.Olu hlobo lwefuse lwenzelwe ukuhlala luvulekile xa ubushushu be-ambient bufikelela kwinqanaba elithile.Iifusi ezonakeleyo zinokukhokelela kwiindlela ezikhokelela ekuthinteleni umsinga ogqithisileyo ekonakaliseni iintambo zendlu.Ingxaki ngefuse kukuba inesiphumo esinye kuphela.Ngalo lonke ixesha i-fuse yonakalisiwe, kufuneka itshintshwe enye entsha.I-breaker circuit inokwenza umsebenzi ofanayo njenge-fuse, kodwa ingaphinda isetyenziswe ngamaxesha amaninzi.Ngethuba nje i-current ifikelela kwinqanaba elinobungozi, iya kukhokelela ngokukhawuleza indlela.
Umgaqo osisiseko: Intambo ephilayo kunye nentambo engathathi hlangothi kwisekethe ixhunyiwe kumacala omabini ombane.Xa iqhosha likwimeko edibeneyo, i-current ikhutshwa kwisixhobo se-terminal esisezantsi, ngokulandelelanayo ihamba nge-electromagnetic, i-AC contactor ehambayo, i-static data AC contactor, kwaye ekugqibeleni ikhutshwe kwisixhobo esiphezulu se-terminal.Umbane okhoyo unokuba yimagnethi yombane.Amandla kazibuthe eveliswa yi-electromagnetic ayanda ngoku.Ukuba okwangoku kuncitshisiwe, amandla omagnetic nawo aya kuba buthathaka.Xa yangoku itsibela kumthamo onobungozi, ingqiqo yokufakelwa kwe-electromagnetic yenza amandla omagnetic omelele ngokwaneleyo ukuhambisa intonga yentsimbi eqhagamshelwe kunxibelelwano lokutshintsha amandla.Oku kuya kubangela ukuba umnxibelelwano we-AC ohambayo ajike kwaye ashiye i-static data AC contactor, evula isiphaluka.Umsinga nawo uphazamisekile.Imichilo yentsimbi ekwaziyo ukunxiba yenziwe ngokomgaqo ofanayo.Ngokungafaniyo nesiNgesi, akufuneki ukuba inike i-electromagnet kinetic energy, kodwa endaweni yoko ivumela umcu wentsimbi ukuba ugobe phantsi komsinga ophezulu, othi emva koko uqhube unxibelelwano.Abanye abaphuli beesekethe bahambisa iswitshi yamandla ngokwentlawulo yeziqhushumbisi.Xa umsinga udlula umgangatho othile, uya kutshisa izinto ezinokutsha kunye neziqhumayo, kwaye emva koko utyhale intonga yepiston ukucofa iswitshi.
Uphuculo: Abaphuli beesekethe abaphambili ngakumbi bakhetha ukushiya izixhobo zombane ezilula kwaye basebenzise i-elektroniki (ishishini le-semiconductor) ukubona amanqanaba akhoyo.I-Ground Fault Interrupter (GFCI) Olu luhlobo olutsha lwe-circuit breaker.Ezi ngqungquthela zesekethe azigcini nje ukuthintela umonakalo kwi-wiring yendlu, kodwa zikhusela abantu kwi-electrocution.
Umgaqo ophuculweyo: I-GFCI iya kuqhubeka nokubona i-current in neutral kunye neengcingo eziphilayo kwisekethe.Xa konke kuhamba kakuhle, imisinga kwiisekethe ezimbini kufuneka ifane ncam.Nje ukuba ukungathathi hlangothi okuphilayo kusekelwe ngokukhawuleza (umzekelo, abanye abantu bachukumise ngengozi ukungathathi hlangothi okuphilayo), okwangoku kwi-live neutral kuya kunyuka ngokukhawuleza, kodwa ukungathathi hlangothi akuyi.Xa i-GFCI ibona into enjalo, ikhupha ngokukhawuleza isiphaluka ukuthintela umbane.Ii-GFCIs akunyanzelekanga ukuba zilinde kude kube ngoku kunyuke ukuya kumanqanaba anobungozi, ngoko ke ireyithi yokuphendula ikhawuleza kakhulu kunezaphuli-mthetho eziqhelekileyo.
