Ifakwe njani intambo yesaphuli sesekethe?Ngaba umgca ongenanto ukhohlo okanye ulungile?
Usombane jikelele uya kucebisa umniniyo ukuba afakele ii-circuit breakers ukwenzela ukukhusela ukhuseleko lombane wasekhaya.Oku kungenxa yokuba i-breaker circuit inokuhamba ngokuzenzekelayo ukunqumla umbane xa umgca wekhaya ungaphumeleli, ngoko ke ukunciphisa ilahleko yengozi.Kodwa ngaba uyazi ukuba i-breaker circuit ifakwe njani?Ngaba ikwashiywe ngumgca ongeyomfuneko wasekunene?Jonga ukuba uthini umcibi wombane.
1. Yintoni i-circuit breaker?
I-circuit breaker sisixhobo sokutshintsha esikwaziyo ukuvala, ukuthwala kunye nokuphula umsinga phantsi kweemeko eziqhelekileyo zesekethe, kunye nokuthwala kunye nokwaphula i-current phantsi kweemeko zesekethe ezingaqhelekanga (kubandakanywa neemeko zesekethe ezimfutshane) phakathi kwexesha elithile.Luhlobo lokutshintsha, kodwa olwahlukileyo kutshintshi esiqhele ukulusebenzisa, i-breaker yesiphaluka ikakhulu ukunqumla i-high-voltage yangoku, xa ukusilela kwenkqubo yethu, kunokukhawuleza ukunqumla yangoku, ukuze kuthintelwe ubuzaza. uphuhliso lwemeko, ukukhusela impahla yabantu.Sisixhobo esilungileyo sokhuseleko.
Ukusebenzisa i-circuit breaker kwenza ubomi bethu bube lula, ngokuthe ngcembe ebomini babantu, ukuzisa ubomi obukhuselekileyo.
2. Ekhohlo i-null, i-right fire
Andizange ndiyazi intsingiselo ekuqaleni.Ngokuthe ngcembe, njengoko ndifunda ngakumbi, ndiye ndazi ukuba into ebizwa ngokuba “yi-null ekhohlo, umlilo osekunene” yindlela nje ejongene ne-jack, ijekhi yasekhohlo ngumgca ongenanto, ijekhi elungileyo ngumgca womlilo, kuko konke.
Isokethi kwiingcingo, ayinakushiywa ngumlilo wasekunene.Ezinye iitheminali zicwangciswe ngokuthe tye, kodwa xa ujongene nazo (ngasemva kwesokethi), zikwindlela echaseneyo yeesokethi.Ezinye iitheminali zicwangciswe ngobude, singasathethi ke ngasekhohlo nasekunene.
ngoko ke, kuseyimfuneko ukulandela ileyibhile yesithuba se-terminal xa udibanisa iingcingo.Ukuba iphawulwe ngo-L, umgca womlilo uya kudibaniswa.N imele umgca ongenanto.
3. Isikhundla socingo lwe-null line kunye ne-null line
Lonke utshintsho lokuvuza kufuneka luqhagamshelwe kumgca ongenanto.Ukuba akukho mgca we-null, kungenxa yoqhagamshelwano olungalunganga.Ukutshintsha ukuvuza kwendlu, ngokwenani leepali, kunokwahlulwa zibe ziindidi ezimbini: ukuvuza kwe-1P kunye nokuvuza kwe-2P.
Zombini izitshixo zineseti ezimbini zeetheminali (enye ngaphakathi nangaphandle ibala njengeseti enye).Elinye lamaqela amabini ezithuba ze-terminal kunye nokuvuza kwe-1P inophawu lwe-N. Xa i-wiring, i-null lines kufuneka ixhunywe kweli qela lezithuba ze-terminal kunye nelinye iqela lemigca yomlilo.Ungakhathali malunga nomlilo ongasekhohlo wasekhohlo.I-null line kunye ne-fire line direction ye-switch ayilungiswanga, kwaye umyalelo wee-terminals zeempawu ezahlukeneyo kunye neemodeli zihluke.Xa ufaka iintambo, indawo yesona siphelo se-N siyakuthi sithathe indawo.
Akukho kuchongwa kweebhloko ezimbini zokuvuza kwe-2P, oku kuthetha ukuba sinokukhetha umyalelo wocingo ngokungaqhelekanga.Nangona kunjalo, ngokuqhelekileyo kucetyiswa ukuba ubhekiselele kwi-1P yokuvuza ulandelelwano lwe-wiring kwibhokisi yokusabalalisa ukuqinisekisa ukulandelelana kwe-wiring efanayo phakathi kwezi zibini.Ngoko ulungelelwaniso lomgca luya kuba lubukeka lungcono kwaye lulungele ukugcinwa kwixesha elizayo.
Kungakhathaliseki ukuba luhlobo luni lokutshintsha ukuvuza, musa ukudibanisa umgca we-null kwitshintshi.
4. Kufuneka idibaniswe njani i-breaker circuit?
Makhe sithathe i-2P i-circuit breaker njengomzekelo, jongana ne-circuit breaker njengomfanekiso olandelayo.
Iitheminali ezimbini eziphezulu ziqhele ukuba yitheminali engenayo kwaye ezimbini ezisezantsi zibe yitheminali ephumayo.Ekubeni le yi-2P ye-circuit breaker, inokulawula ukuvulwa nokuvalwa kweesekethe ezimbini.Ukuba kukho i-capital N kwelinye icala le-terminal, le terminal ixhunyiwe kumgca we-zero, kwaye enye ixhunyiwe kumgca womlilo.
Enyanisweni, ii-circuit breakers ezifana nezi zingasentla zihlala zinamandla kakhulu (kumandla asetyenziswa yindlu).Ukuze ukhuseleke, ii-breakers ezininzi ze-1P ziya kongezwa ngasemva kwesekethe.Abaphuli beesekethe abanjalo ngokuqhelekileyo banamandla aphantsi.
Kwi-breaker circuit ye-1P, kulungile ukudibanisa ngokuthe ngqo ucingo oluphilayo ukusuka kwi-2P ye-circuit breaker.Ngokuqinisekileyo, kwi-circuit breaker ye-2P, unokuqhubeka nokudibanisa umgca womlilo kunye nomgca we-null.Ukuba akukho phawu lwe-N kwi-breaker circuit, ngokuqhelekileyo ilandelwa ngumlilo osekhohlo kunye ne-right null.
5. Ukuba ucingo lubuyela umva, kuya kwenzeka ntoni?
Qhagamshela umgca we-null ongalunganga kunye nomgca womlilo we-2P we-circuit breaker kunye ne-2P yokuvuza i-circuit breaker ayikho ingxaki enkulu.Impembelelo kuphela kukuba ibonakala ingabonakali, ukuphazamiseka kulondolozo kuba ingcali kufuneka iphinde ifumane umgca we-null kunye nomgca womlilo.
Xa inqanyuliwe, i-1P+N i-circuit breaker kunye ne-1P yokuvuza i-circuit breaker inokukhupha kuphela ucingo lomlilo----umgca oqhagamshelwe kwi-terminal engaphawulwanga.Ukuba umgca we-null kunye nomgca womlilo udityaniswe ngokungalunganga, xa i-breaker yesiphaluka inqanyuliwe, umgca we-null unqanyuliwe ngokwenene.Nangona kungekho okwangoku kwisekethe, kusekho i-voltage.Ukuba umntu uyayibamba, uya kubanjwa ngumbane.
Umgca we-null we-1P i-breaker circuit i-null discharge, ngoko akulula ukudibanisa okungalunganga.Isiphumo soxhulumaniso olungalunganga lwe-1P ye-circuit breaker lufana nolo lwe-reverse uxhumano lwe-null line kunye nomgca womlilo we-1P + N i-breaker circuit.
