    Yintoni i-RCBO?

    I-RCBO imele iResidual Current Breaker enokhuseleko lwangoku.I-RCBO idibanisa ukusebenza kwe-MCB kunye ne-RCD / RCCB.Xa kukho ukuvuza kwangoku, i-RCBO ijikeleza yonke isekethe.Ngenxa yoko, izinto zangaphakathi zemagnethi/i-thermal zesaphuli sesekethe zinokukhuba isixhobo sombane xa isekethe igcwele kakhulu.

    1. Intsalela yangoku, okanye iLeakage yoMhlaba - Kwenzeka xa kukho ikhefu ngempazamo kwisekethi ngenxa yeentambo zombane ezingekho mgangathweni okanye iingozi zeDIY ezifana nokubhoboza ngentambo xa ufaka ihuku yomfanekiso okanye ukusika intambo ngomtshini wengca.Kulo mzekelo umbane kufuneka uye ndaweni ithile kwaye ukhethe eyona ndlela ilula yokuhamba ngesixhobo sokucheba ingca okanye ukomba uye kumntu obangela ukothuka kombane.
    2. I-Over-current ithatha iindlela ezimbini:
    a.Ukulayisha ngaphezulu - Kwenzeka xa izixhobo ezininzi zisetyenziswa kwisekethe, ukuzoba umthamo wamandla odlula umthamo wentambo.
    b.Isekethe emfutshane - Iyenzeka xa kukho unxibelelwano oluthe ngqo phakathi kwabaqhubi abaphilayo kunye nabangathathi hlangothi.Ngaphandle kokuchasana okubonelelwa yimfezeko yesekethe yesiqhelo, umsinga wombane ujikeleza isekethe kwiluphu kwaye uphinda-phinda i-amperage ngamawakawaka amaxesha ngeemilliseconds nje kwaye uyingozi kakhulu kuno-Overload.

    Nangona i-RCCB iyilelwe kuphela ukukhusela ekuvuzeni komhlaba kwaye i-MCB ikhusela kuphela ngokugqithisileyo, i-RCBO ikhusela kuzo zombini iindidi zesiphene.

    Kubomi bokwenyani, amacandelo ombane afana nentsalela yangoku yezaphuli-mthetho (ezaziwa ngokuba zizitshixo zokuvuza) zisetyenziswa phantse kuyo yonke indawo enombane.Isetyenziselwa kakhulu ukufumanisa i-residual current, thelekisa ixabiso langoku elishiyekileyo kunye nexabiso lereferensi, kwaye unqamule uqhagamshelwano oluphambili lwesiphaluka xa ixabiso langoku eliseleyo lidlula ixabiso lereferensi.Xa ukothuka kombane wobuqu okanye ukuvuza kombane ngoku kudlula ixabiso elichaziweyo, intsalela yesaphuli sesekethe yangoku inokuphelisa ngokukhawuleza unikezelo lwamandla olunempazamo ngexesha elifutshane kakhulu, ikhusele ukhuseleko lwezixhobo zobuqu nezombane, kwaye kwangaxeshanye ikhusele izixhobo zombane. ukulayisha ngaphezulu okanye isiphaluka esifutshane somgca kunye nemoto, kwaye ingasetyenziselwa ukutshintshela rhoqo imigca kunye nokuqala okungaqhelekanga kweenjini, kwaye sisixhobo sombane esisetyenziswa ngokubanzi kwimveliso kunye nobomi.

    1. I-relay yokukhusela ukuvuza ibhekisela kwisixhobo sokukhusela ukuvuza esinomsebenzi wokubona kunye nokugweba ukuvuza kwangoku, kodwa ayinayo umsebenzi wokuqhawula kunye nokudibanisa isiphaluka esikhulu.I-relay yokukhusela ukuvuza yenziwe nge-zero-sequence transformer, ukukhululwa kunye noqhagamshelwano oluncedisayo kwisignali yemveliso.Iyakwazi ukusebenzisana nokutshintsha okuzenzekelayo kwamandla aphezulu njengokhuseleko oluqhelekileyo lwegridi yamandla aphantsi-i-voltage okanye ukuvuza, ukumisa umhlaba okanye ukukhuselwa kwe-insulation monitoring yendlela enkulu.Xa kukho ukuvuza kwangoku kwisekethe ephambili, ekubeni uqhagamshelwano oluncedisayo kunye nokukhululwa kokwahlukana kwentambo yesekethe engundoqo idityaniswe kuthotho ukwenza isekethe, uqhagamshelwano oluncedisayo ludityaniswe nokukhululwa kokwahlukana kwaye luqhawule ukutshintshela umoya, i-AC contactor, njl njl.Abancedisi abancedisayo banokudityaniswa nezixhobo zesandi kunye nokukhanya kokukhanya ukukhupha isignali ye-alarm yokuvuza ukubonakalisa isimo se-insulation yomgca.2. Umtshini wokukhusela ukuvuza kuthetha ukuba awukwazi kuphela ukuvula okanye ukucima isiphaluka esiphambili njengamanye ama-circuit breakers, kodwa unomsebenzi wokubona kunye nokugweba ukuvuza kwangoku.Xa ukuvuza okanye ukutshatyalaliswa kwe-insulation kwenzeka kwisiphaluka esiphambili, ukutshintshwa kokukhusela ukuvuza kunokusekwa kwi-element switching eguqula isiphaluka esiphambili okanye icime ngenxa yesigwebo.Isebenzisana kunye ne-fuses kunye ne-thermal relays ukwenza into esebenzayo ngokupheleleyo ye-low-voltage switch.
