Yintoni umsebenzi we-circuit breaker, umgaqo wokusebenza we-circuit breaker inkcazo ecacileyo
Xa inkqubo isilela, isenzo sokukhusela isici sesiphoso kunye nokungaphumeleli kokusebenza kwe-circuit breaker yenqaba ukuhamba, hamba i-breaker circuit ekufutshane ye-substation ngokukhusela isici esiphosakeleyo, kwaye itshaneli ingasetyenziselwa ukwenza i-wiring ye i-distal circuit breaker trip ngexesha elifanayo libizwa ngokuba yi-circuit breaker failure protection.
Ngokuqhelekileyo, emva kwesenzo samacandelo esigaba sangoku, amaqela amabini okuqhagamshelwa kokuqala aphumayo, kwaye iindawo zoqhagamshelwano zangaphandle zokukhusela isenzo zixhunyiwe kuchungechunge kwisekethe, ikhonkco yebhasi okanye isahlulo secandelo lokungaphumeleli kwe-breaker breaker ukuqala ukukhuselwa kokungaphumeleli.
Yiyiphi imisebenzi yabaphuli beesekethe
Izaphuli zesekethe zisetyenziswa ikakhulu kwiimotor rhoqo kunye neziguquli umthamo omkhulu kunye nezitishi.I-Circuit breaker inomsebenzi wokwahlula umthwalo wengozi, kwaye isebenzisana nokukhusela okuhlukeneyo kwe-relay ukukhusela izixhobo zombane okanye imigca.
I-Circuit breaker isetyenziswa ngokubanzi ekukhanyeni kwe-voltage ephantsi, inxalenye yamandla, inokudlala indima yokusika ngokuzenzekelayo isiphaluka;i-breaker circuit kunye ne-overload kunye nokukhusela isiphaluka esifutshane kunye neminye imisebenzi emininzi, kodwa ingxaki yomthwalo ophantsi kufuneka ilungiswe i-switch yokuqhawula idlala indima yokuzahlula kombane, kunye nomgama we-creepage we-circuit breaker akwanelanga.
Ngoku kukho isaphuli sesekethe esinomsebenzi wokuzihlukanisa, oyinto eqhelekileyo yesaphuli sesekethe kunye nomsebenzi wokuqhawula kabini kwenye.Umqhekezi wesiphaluka kunye nomsebenzi wokuzihlukanisa unokuba ngumnqamuli womzimba.Enyanisweni, i-disconnector switch ayisebenzisi ngokubanzi kunye nomthwalo, ngelixa i-breaker circuit inesiphaluka esifutshane, ukhuseleko lomthwalo ogqithisiweyo, uxinzelelo kunye neminye imisebenzi yokukhusela.
Umgaqo wokusebenza we-breaker circuit yinkcukacha
Uhlobo olusisiseko: Isixhobo esilula sokukhusela isiphaluka yi-fuse.I-fuse yinto nje yocingo oluncinci kakhulu, kunye necala lokukhusela kwaye emva koko liqhagamshelwe kwisekethe.Emva kokuba isiphaluka sivaliwe, yonke imisinga kufuneka ihambe ngokukhoyo kwi-fuse -- fuse njengombane ofanayo kwezinye iindawo kwisiphaluka esifanayo.I-fuse yenzelwe ukuba idibanise xa ubushushu bufikelela kwinqanaba elithile.Ukugrumba i-fuse kunokubangela iindlela ezivulekileyo ukuthintela umsinga ogqithisileyo ekonakaliseni iintambo zendlu.Ingxaki ngefuse kukuba inokusebenza kube kanye kuphela.Nanini na xa i-fuse itshisiwe, kufuneka itshintshwe.Abaphuli beesekethe bangenza indima efanayo njenge-fuses, kodwa bangasetyenziswa ngokuphindaphindiweyo.Ngokukhawuleza ukuba umbane ufikelela kwinqanaba eliyingozi, ngokukhawuleza kubangela isiphaluka esivulekileyo.
Umgaqo osisiseko wokusebenza: ucingo lomlilo kwisekethe luxhunyiwe kuzo zombini iziphelo zokutshintsha.Xa iswitshi ibekwe kwimeko, umsinga uphuma uphuma kwi-terminal esezantsi, ngokulandelelanayo ngomzimba we-electromagnetic, abafowunelwa beselula, abafowunelwa abangatshintshiyo, kwaye ekugqibeleni usuka kwi-terminal ephezulu.Le yangoku ingenza imagnethi umazibuthe.Amandla kazibuthe eveliswa nguzibuthe we-electromagnetic ayanda ngoku, kwaye ukuba yangoku iyancipha.Xa ngoku utsiba kwinqanaba eliyingozi, amava EM avelisa amandla amakhulu ngokwaneleyo kazibuthe ukutsala intonga yentsimbi eqhagamshelwe kwikhonkco switsha.Oku kubangela ukuba i-contactor ehambayo iqhube kwaye ishiye i-static contactor, ngoko inqumle isiphaluka.Umsinga wombane nawo uphazamisekile.Ibha ye-bimetal yenzelwe ngokusekelwe kumgaqo ofanayo, umahluko kukuba akukho mfuneko yokunika amandla omzimba we-electromagnetic apha, kodwa ivumela ibha yentsimbi ukuba igobe ngokuphezulu, kwaye emva koko iqalise isixhobo sokudibanisa.Abanye abaphuli beesekethe baphinda bazalise iziqhushumbisi ukuhambisa iswitshi.Xa umsinga udlula umgangatho othile, utshisa izinto eziqhumayo kwaye emva koko uqhube ipiston ukuvula iswitshi.
Imifuziselo eyomeleziweyo: Izaphuli zesekethe eziphucukileyo zishiya izixhobo zombane ezilula kwaye endaweni yoko zisebenzisa izixhobo zombane (izixhobo zesemiconductor) ukujonga amanqanaba akhoyo.I-Ground fault circuit breaker (GFCI) luhlobo olutsha lwe-circuit breaker.Le ngqungquthela yesiphaluka ayinakunqanda kuphela umonakalo kwi-wiring yendlu, kodwa iphinde ikhusele abantu ekutshitshisweni kombane.
Umsebenzi ophuculweyo: I-GFCI ihlala ibeka iliso langoku kwi-zero kunye nemigca yomlilo kwisekethe.Xa yonke into iqhelekile, okwangoku kuyo yomibini imigca kufuneka ifane ncam.Emva kokuba umgca womlilo usekelwe ngokuthe ngqo (umzekelo, umntu uthintela ngengozi umgca womlilo), okwangoku kumgca womlilo wenyuka ngokukhawuleza, ngelixa umgca we-zero ungekho.I-GFCI inqumle isekethe ngokukhawuleza emva kokubona le meko ukuthintela izingozi zombane.Ngenxa yokuba i-GFCI inokuthatha inyathelo ngaphandle kokulinda ide inyuke iye kwinqanaba eliyingozi, isabela ngokukhawuleza kunamaqhekeza aqhelekileyo.
