Iinkcukacha zeMveliso

Intshayelelo:

Isixhobo esisalayo (i-RCD), i-residual-current circuit breaker (RCCB) sisixhobo sokhuseleko sombane esophula ngokukhawuleza isekethe yombane ngokuvuza kwangoku ukuya emhlabeni.Kukukhusela izixhobo kunye nokunciphisa umngcipheko wokwenzakala okumandundu kwishock yombane eqhubekayo.Ukwenzakala kusenokubakho kwezinye iimeko, umzekelo ukuba umntu ufumana umothuko omfutshane ngaphambi kokuba isekethe yombane ibe yodwa, awe emva kokufumana umothuko, okanye ukuba umntu ubambe zombini iikondaktara ngaxeshanye.

I-JCR2-125 yenzelwe ukukhupha isiphaluka ukuba kukho ukuvuza kwangoku.

I-JCR2-125 Izixhobo eziseleyo zangoku (i-RCDs) zikuthintela ekufumaneni izinto ezothusayo zombane.Ukhuseleko lwe-RCD lusindisa ubomi kwaye lukhusela emlilweni.Ukuba ubamba ucingo olungenanto okanye ezinye izinto eziphilayo zeyunithi yomthengi, iya kugcina umsebenzisi wokugqibela engonakaliswa.Ukuba isifakeli sinqumla intambo, izixhobo zangoku ezishiyekileyo ziya kucima amandla aqukuqela emhlabeni.I-RCD iya kusetyenziswa njengesixhobo esingenayo esondla unikezelo lombane kwii-breakers zesekethe.Kwimeko yombane wombane, i-RCD iphuma kwaye ikhuphe unikezelo kubaphakeli beesekethe.

Isixhobo sangoku esishiyekileyo okanye esaziwa ngcono njenge-RCD sisixhobo esiphambili sokhuseleko kwihlabathi lombane.I-RCD isetyenziselwa ikakhulu ukukhusela umntu kumothuko wombane oyingozi.Ukuba kukho isiphene kwisixhobo sombane endlwini, i-RCD iphendula ngenxa yokunyuka kwamandla kwaye ikhuphe umbane wombane.I-RCD yenzelwe ukuba iphendule ngokukhawuleza.Isixhobo esisebenza ngoku esishiyekileyo songamela umsinga wombane kunye nethutyana nje laso nasiphi na isenzo esingaqhelekanga eso sixhobo sisabela ngokukhawuleza.

Ii-RCD's zikhona ngeendlela ezahlukeneyo kwaye zisabela ngokwahlukileyo ngokuxhomekeke kubukho bamacandelo e-DC okanye iifrikhwensi ezahlukeneyo.Inqanaba lokhuseleko ababonelela ngalo kwimisinga ephilayo likhulu kune-fuse eqhelekileyo okanye i-breaker circuit.Ezi RCD zilandelayo ziyafumaneka kunye neesimboli ezifanelekileyo kwaye umyili okanye umfakeli kufuneka akhethe isixhobo esifanelekileyo sosetyenziso oluthile.

Uhlobo S (Ixesha-libazisekile)

Uhlobo lwe-S RCD sisixhobo se-sinusoidal residual sangoku esibandakanya ukulibaziseka kwexesha.Inokufakwa phezulu ukusuka kwi-RCD yodidi lwe-AC ukubonelela ngokukhetha.I-RCD ebambezelekile ixesha ayinakusetyenziselwa ukhuseleko olongezelelweyo kuba ayiyi kusebenza ngexesha elifunekayo le-40 mS.

Uhlobo AC

Uhlobo lwe-AC RCDs (Uhlobo Jikelele), oluqhelekileyo lufakelwa kwiindawo zokuhlala, zenzelwe ukusetyenziselwa ukutshintshwa kwe-sinusoidal residual current ukukhusela izixhobo ezixhatshazwayo, ezikwaziyo okanye ezithintekayo kwaye ezingenazo naziphi na izinto ze-elektroniki.

Ii-RCD zodidi oluqhelekileyo azinalo ukulibaziseka kwexesha kwaye zisebenza ngokukhawuleza ekuboneni ukungalingani.

Uhlobo A

Uhlobo A RCDs zisetyenziselwa ukutshintshana kwe-sinusoidal residual current kunye ne-residual pulsating current ngqo ukuya kuthi ga kwi-6 mA.

Ndizivavanya njani iintlobo ezahlukeneyo ze-RCD?
Akukho mfuneko zongezelelweyo ukuba isifakeli sijonge ukusebenza ngokuchanekileyo ngelixa siphantsi kwe-DC residual current.Olu vavanyo lwenziwa ngexesha lenkqubo yokuvelisa kwaye lubizwa ngokuba luvavanyo lohlobo, olungahlukanga kwindlela esithembele ngayo ngoku kwi-circuit-breakers phantsi kweemeko eziphosakeleyo.Uhlobo lwe-A, B kunye no-F RCDs luvavanywa ngendlela efanayo ne-AC RCD.Iinkcukacha zenkqubo yovavanyo kunye namaxesha amaninzi okuqhawula angafumaneka kwi-IET Guidance Note 3.
Kuthekani ukuba ndifumene udidi lwe-AC RCD ngelixa ndisenza uhlolo lombane ngexesha lengxelo yemeko yofakelo lombane?
Ukuba umhloli unenkxalabo yokuba i-DC eshiyekileyo inokuchaphazela ukusebenza kohlobo lwe-AC RCDs, umxhasi kufuneka aziswe.Umxhasi kufuneka aziswe ngeengozi ezinokuthi zivele kwaye uvavanyo lwemali eshiyekileyo ye-fault current ye-DC kufuneka yenziwe ukugqiba ukuba i-RCD ikulungele ukusetyenziswa ngokuqhubekayo.Ngokuxhomekeke kwisixa sentsalela ye-DC fault current, i-RCD emfamekiswe yintsalela ye-DC fault current kusenokwenzeka ukuba ingasebenzi nto leyo enokuba yingozi njengokungabi nayo i-RCD efakiweyo kwasekuqaleni.
Ukuthembeka kwinkonzo yee-RCDs
Izifundo ezininzi malunga nokuthembeka kwenkonzo ziye zaqhutywa kwii-RCD ezifakwe kuluhlu olubanzi lofakelo olubonelela ngengqiqo malunga nemiphumo yokuba iimeko zokusingqongileyo kunye nezinto zangaphandle ezinokuthi zibe nazo ekusebenzeni kwe-RCD.
