Ukusetyenziswa kwezixhobo zombane ezingagcinwanga kakuhle okanye eziphelelwe lixesha kwiindawo ezinobungozi kubeka abasebenzi kunye neendwendwe emngciphekweni wokutshatyalaliswa kombane, ngakumbi ukuba badibana ngqo nomhlaba.
Thembela kwii-RCD zokhuseleko olongezelelweyo kwiimpazamo.Uninzi lweebhodi zokutshintsha ezikhoyo ezifakwe kwiindawo zokwakha e-UK zinee-AC RCDs.
I-AC RCDs ayifanelekanga ukusetyenziswa kunye nezixhobo ezininzi zombane zanamhlanje kunye nezixhobo ezisetyenziswa kwiindawo zokwakha, ngaphandle kokuxhathisa ukufudumeza kunye nokukhanyisa imithwalo - bona i-BS7671 Amendment 2.
Iimfuno ngokubanzi zale nkqubo zinikwe kwinxalenye ephambili yenkqubo yokucima amandla ngokuzenzekelayo.Isihlomelo sesi-2 ekupheleni kwe-§ 531.3.3 ithi: "I-AC yodidi lwe-RCD* iya kusetyenziselwa ukusebenza kufakelo olusisigxina kunye nomthamo owaziwayo womthwalo ongenalo icandelo le-DC."
Ukufaneleka kokubeka iliso kunye nokulawula izixhobo eziqhagamshelwe kumbane wentsimi, ngokukodwa izixhobo ze-plug-in, ngumba omkhulu wezempilo kunye nokhuseleko.Iingozi ezinxulumene nokudibanisa izixhobo zesigaba sesithathu kumthombo wamandla okhoyo okhuselweyo luhlobo olungalunganga lwe-RCD luyingozi enokwenzeka kuzo zonke iziza e-UK.Oku kuqatshelwe kwaye kuvunyelwe kwi-HD 60364-7-704 2018 Isihlomelo ZB: Kwiindawo zokwakha zaseJamani kunye nokudilizwa / Zonke iisokethi ze-3 zesigaba sesithathu ukuya kwi-63 A kufuneka zikhuselwe ngohlobo lwe-B RCDS.
Ufakelo lwexeshana: Nasiphi na isixhobo esivaliweyo saza safuduselwa kwindawo entsha yesiza okanye esithunyelwe ukuba sihlaziywe/silungiswe siya kuthobelana neemfuno zamvanje zokhuseleko, okt sihlelwa njengesifakelo esitsha kwaye sithobelana neemfuno zangoku zolawulo.
Ukudibanisa izixhobo ezitsha: Izikhokelo zezempilo kunye nokhuseleko (jonga ngezantsi) zigxininisa imfuno yabasebenzi abafanelekileyo ukuqinisekisa ukuba umbane kunye nezixhobo zokukhusela zifanelekile kwizixhobo ezixhunyiwe, umzekelo, uhlobo lwe-RCD kufuneka lufaneleke kwisixhobo esixhunyiwe / isixhobo.– bona BS 7671 531.3.3
* Ingcaciso esemthethweni: “Iya” ithetha ukuba umntu unesibophelelo okanye uxanduva lokwenza isenzo.
Isikhokelo esinikezelwe kwi-HSE Guidance Document kunye ne-BS7671 isekela ukuthotyelwa kweemfuno ze-UK Health and Safety Act.
Ii-RCD ezikhethwe ngokufanelekileyo zibonelela ngokukhuselwa kwesiphoso kunye nokukhuselwa okongeziweyo - jonga iiMfuno zoVavanyo loMngcipheko: I-HSE Manual Working on Electrical Equipment. Isikhokelo (i-Indent 4 & 5) sichaza ukuba ngaphambi kokudibanisa izixhobo, "umntu onobuchule" kufuneka ahlole ukubonelela. Isikhokelo (i-Indent 4 & 5) sichaza ukuba ngaphambi kokudibanisa izixhobo, "umntu onobuchule" kufuneka ahlole ukubonelela.Incwadana (imihlathi yesi-4 kunye ne-5) ithi "umntu onobuchule" kufuneka ahlolisise umbane ngaphambi kokudibanisa izixhobo.Izikhokelo (ezifakwe kwi-4 kunye ne-5) zichaza ukuba "umntu oqeqeshiweyo" kufuneka ahlole amandla ngaphambi kokuba adibanise isixhobo.Oku kubandakanya ukufaneleka kunye nokusebenza kwazo zonke izixhobo zokukhusela ze-RCD ezifakwe ngokuhambelana nezixhobo.
Imithwalo yezigaba ezithathu ezibandakanya ii-inverters (umz. iimpompo, ii-compressors, i-seal, i-welders, njl. njl.) zivelisa i-frequency ephezulu kunye nemisinga yokuvuza egudileyo ye-DC ephazamisana ne-RCDs eqhelekileyo.Umgaqo we-531.3.3 (iv) ufuna ukusetyenziswa kwee-RCD zodidi lwe-B ukubonelela ngezinga elifunekayo lokukhusela ezi ntlobo zemithwalo.
“Kufuneka uthathe amanyathelo okhuseleko kwingozi yokufa okanye yokwenzakala ngumbane.Izixhobo zombane kufuneka zikhuseleke kwaye zigcinwe ngokufanelekileyo.”I-HSE igxininisa ukubaluleka koMbane kwiMimiselo yeNdawo yoMsebenzi ka-1989 kunye nesikhokelo esixhasayo sokunciphisa/ukuphelisa iingozi ezinxulumene nezixhobo eziyilwe ngendlela engafanelekanga neziyilwe ngokungafanelekanga, ezisetyenziswa ngokungafanelekanga nezigcinwe kakuhle.Umbane kwiNdawo yoMsebenzi yeMithetho ka-1989, uMgaqo wesi-4-(1) “Zonke iinkqubo ziya kwakhiwa ngawo onke amaxesha ukuze zithintele iingozi kangangoko kunokwenzeka.”I-HSE Manual echaphazelekayo (HSR25) ibeka iimfuno ezimalunga: noyilo (umhlathi 62), iimeko ezinokubonwa kwangaphambili kunye nokusetyenziswa (umhlathi 63), iimpawu zomenzi, izixhobo ezifanelekileyo zokukhusela zombane… (umhlathi 64)), kunye “nokhuseleko lwezixhobo” .inkqubo ixhomekeke kukhetho oluchanekileyo lwazo zonke izixhobo zombane.Inkqubo”.. (iphe. 65)
Okokuthi, i-RCD ibonelela ngokhuseleko, ngoko ke, xa ukhetha uhlobo lwe-RCD, kuyimfuneko ukuqwalasela iimfuno kunye neengcebiso ezinikwe kwi-BS 7671 531.3.3, ngokusekelwe kuluhlu lwezixhobo ezinokudityaniswa emva kwe-RCD ekhuselweyo. indawo yokuphuma.
Ii-RCD kunye nee-RCD zifanelekile kwisiphaluka sokugqibela / ukukhuselwa kwe-socket: ukulinganiswa kwazo okusisigxina kukulungele ukukhusela i-30 mA ekuhlengahlengisweni okungagunyaziswanga ngabasebenzi abangaqeqeshelwanga (umbane) - bona i-BS 7671 531.3.4.1 I-CBR kunye ne-MRCD inemilinganiselo yokulungelelanisa, inokusebenza / ingcali njengoko kuyalelwe - jonga igatya 531.3.4.2 le-BS7671.
PHAWULA.Ii-MRCD zisetyenziswa kunye nezixhobo ezizimeleyo ezingasebenziyo kwaye ke kufuneka ziqinisekiswe emva kwendibano ye-OEM kunye noqhagamshelo (BSEN60947-2 Annex M).Oku kwenziwa ukuvavanya ixesha elipheleleyo lokuqhawula i-MRCD + MCB + S/Trip okanye i-U/Release assembly njengenxalenye yovavanyo lokugqibela lwendibano:
Ukunikezelwa kweemeko ezinzima zeendawo zokwakha kunye nemingcipheko ephezulu yokusebenzisa izixhobo zombane ngaphandle, imithetho ilula: izixhobo kufuneka zilungele ukusetyenziswa, zigcinwe kakuhle kwaye zikhuselekile ukusebenzisa.Oku kubandakanya ukukhetha uhlobo olufanelekileyo lwe-RCD, ukukhusela ngokufanelekileyo izixhobo ezifana ne-RCDs ukusuka kwindalo, kunye nokuzigcina zisebenza kakuhle.Khangela rhoqo kwaye uvavanye ukuqinisekisa ukuba i-RCD ibonelela ngezinga elifunekayo lokukhusela kwaye ifanelekile kwisixhobo esixhunyiwe.Ngaphambi kokudibanisa izixhobo ezitsha kwi-switchboard ekhoyo - imimiselo ye-HSE idinga "umntu oqeqeshiweyo" ukuvavanya ukunikezelwa kwamandla ukuqinisekisa ukuba kukhuselekile ukusebenzisa izixhobo.
