Uhlengahlengiso lweMeko kunye nokuSetwa kweParameter kubalulekile ekuKhethweni kweRCBO

Xa kukhethwa usasazo lwamandla olusebenzisa umbane ophantsi, abathengi abaninzi banengcamango ephosakeleyo efanayo: kokukhona uvakalelo lwe-I-Residual Current Breaker enokhuselo lwe-Overcurrent, kokukhona ukusetyenziswa kwamandla kuya kuba kukhuselekile. Enyanisweni, eyona nto iphambili kukhuseleko lwangoku olusele luxhomekeke ekuhlengahlengisweni kwemeko kunye nokuseta iiparameter zobungcali, endaweni yokulandela ngokungaboniyo uvakalelo oluphezulu kakhulu.

Useto olungenangqiqo oluphezulu luya kubangela ngokulula ukukhubeka rhoqo kunye nokuphazamiseka okungalindelekanga kombane. Kuphela ngokuthelekisa iiparameter zobugcisa ngokuhambelana nengqiqo yobungcali kushishino apho sinokulinganisela ngokugqibeleleyo ukhuseleko lomntu, uzinzo lokusebenza kwezixhobo kunye nokuthembeka kwemigca yombane.

I-Rated Residual Operating Current (IΔn) yiparameter yokuseta i-core setting ye-residual current breaker enokhuselo olugqithisileyo. I-mainstream current ratings ibandakanya i-30mA, i-100mA kunye ne-300mA, apho i-rating nganye ine-logic yokhuseleko ezimeleyo ngokupheleleyo.

Imodeli ye-30mA ikwinqanaba lokuvavanya okuphezulu, eyenzelwe ngokukodwa ukhuseleko lombane lomntu ngamnye. Amanqanaba e-100mA kunye ne-300mA ziindlela zokuvavanya eziphakathi neziphantsi, ezigxile ekuthinteleni umlilo wombane kunye nokukhusela izixhobo zamandla.

Ukuba izixhobo ze-30mA ezinovakalelo oluphezulu zisetyenziswa ngenkani kwiimeko zoshishino nezorhwebo ezinomthwalo omninzi, umsinga oqhelekileyo wokuvuza kwezixhobo zokusebenza uya kubangela ukukhubeka okungeyomfuneko kwaye uphazamise ukunikezelwa kwamandla orhwebo nokuvelisa. Ngokwahlukileyo koko, ukusebenzisa izithinteli ezinovakalelo oluphantsi kwiindawo zokuhlala nezinabantu abaninzi zorhwebo kuyasilela ukucima umbane ngoko nangoko ngexesha leengozi zombane, nto leyo ebangela iingozi ezinkulu zokhuseleko.

Ingqiqo yokukhetha yobungcali kwiiparamitha zokhuseleko lwangoku oluseleyo ngokusekelwe kwiimeko zesicelo icacile kwaye isemgangathweni:

1.Iimeko zeNdawo zokuhlala nezeMicimbi yezeNtlalo

Beka phambili ukhuseleko lomntu kwaye usebenzise i-30mA rated residual current. Ifanelekile kwiisekethe ze-230V zesigaba esinye, igubungela izibane, iisokhethi kunye neesekethe zekhitshi kunye negumbi lokuhlambela apho kulula khona ukuba abantu bazichukumise iindawo eziphilayo, beqonda ukunqunyulwa kombane ngokukhawuleza ukuze baphephe iingozi zokutshayiswa ngumbane.

2.Imeko zoShishino zoRhwebo neziKhaphukhaphu

Ukulinganisela ukhuseleko kunye nokuzinza kokusebenza ngesetingi ye-100mA. Ithintela ngempumelelo ukukhubeka okubangelwa kukuvuza okuqhelekileyo kwezixhobo ezinamandla aphezulu kwiindawo zokuthenga ezinkulu nakwiifektri ezincinci, ngelixa ibonelela ngokhuseleko lomlilo oluthembekileyo.

3.Imeko zoSasazo lwaMandla kwiMizi-mveliso nakwiMisebenzi enzima

Gxila kukhuseleko lwentambo yombane kunye nezixhobo ngereyithingi ye-300mA. Ifanelekile kwiinkqubo zokusasazwa kwamandla ze-400V zezigaba ezintathu, iyakwazi ukuziqhelanisa neesekethe ezikude kunye neemeko zokusebenza ezinzima ukuqinisekisa ukunikezelwa kombane okuqhubekayo nokuzinzileyo.

Ukuze kuhlangatyezwane neemfuno zokukhetha ezisekelwe kwimeko engasentla,Umbane wabantu RDL8-40 Series RCBOIbonelela ngesisombululo sobungcali esipheleleyo. Ithobela ngokungqongqo imigangatho yamazwe ngamazwe ye-IEC/EN61009, olu luhlu luxhasa umsinga osebenzayo ohlengahlengiswayo osele usele we-30mA/100mA/300mA, kunye nomsinga olinganisiweyo oqala kwi-6A ukuya kwi-40A.

Ifumaneka kwiindlela zokumisela iipali ze-1P+N kunye ne-3P+N, ihambelana ngokupheleleyo neenkqubo zokusasazwa kwamandla ze-230/400V, 50/60Hz AC kunye ne-DC. Idibanisa ukhuseleko oluphezulu, i-short circuit kunye ne-residual current triple, uyilo lwe-electromagnetic luqinisekisa ixesha lokusebenza elingaphantsi kwe-0.1s. Isebenzisa ukufakwa kwe-DIN rail standard ye-35mm ukuze ifakwe ngokukhawuleza,Uthotho lwe-RDL8-40 RCBOIsebenza kakhulu kwiindawo zokuhlala, zorhwebo kunye nezoshishino, isombulula ingxaki eqhelekileyo yokukhetha yokukhubeka ngenxa yobuthathaka obugqithisileyo kunye nemingcipheko yokhuseleko efihlakeleyo ngenxa yobuthathaka obungonelanga.

Ixabiso lokhuseleko leI-RCBO intsalela yangoku eqhekezayoAkukhe kuxhomekeke kuphela kubuchule obuphezulu bokusebenza, kodwa kudibaniso lwesayensi lokufanisa imeko kunye nokuseta iiparameter. Ngoyilo lweeparameter zobungcali, iPeople Electric RDL8-40 Series inika ukhuseleko oluthembekileyo lwangoku oluseleyo kwiimeko ezahlukeneyo zokusetyenziswa kwamandla, okuvumela ukukhetha ngokuchanekileyo kunye nokusetyenziswa kwamandla okukhuselekileyo kubasebenzisi behlabathi.
