EN 61643-11 & IEC 61643-21: 2012 Izixhobo zokukhusela amandla ombane asezantsi-Icandelo lama-21: Izixhobo zokukhusela izixhobo ezixhumeke kunxibelelwano lonxibelelwano kunye nokusayina uthungelwano -Imfuno zokusebenza kunye neendlela zovavanyo

NGEXESHA LOKUQALA

1) IKhomishini ye-Electrotechnical yeHlabathi (IEC) ngumbutho wehlabathi jikelele wokubeka emgangathweni oquka zonke iikomiti zesizwe zombane (Iikomiti zeSizwe ze-IEC). Injongo ye-IEC kukukhuthaza intsebenziswano yamazwe onke kuyo yonke imibuzo emalunga nokubekwa emgangathweni kumabala ombane nawombane. Ukuza kuthi ga ngoku kwaye ukongeza kweminye imisebenzi, i-IEC ipapasha iMigangatho yaMazwe ngaMazwe, iiNkcukacha zobuGcisa, iiNgxelo zezoBuchwephesha, iiNkcukacha eziFumanekayo esiDlangalaleni (PAS) kunye nezikhokelo (emva koku zibizwa ngokuba “lupapasho (I) lwe-IEC”). Amalungiselelo abo anikezelwe kwiikomiti zobugcisa; nayiphi na iKomiti yeSizwe ye-IEC enomdla kwisifundo ekujongwe kuso inokuthatha inxaxheba kulo msebenzi wokulungiselela. Imibutho yamanye amazwe, ekarhulumente kunye nengekho phantsi korhulumente edibana ne-IEC nayo iyathatha inxaxheba kolu lungiselelo. I-IEC isebenzisana ngokusondeleyo ne-International Organisation for Standardization (ISO) ngokwemiqathango emiselwe sisivumelwano phakathi kwale mibutho mibini.

2) Izigqibo ezisesikweni okanye izivumelwano ze-IEC kwimicimbi yezobuchwephesha zichaza, phantse kangangoko kunokwenzeka, ukuvumelana kwezimvo kwilizwe jikelele ngezifundo ezifanelekileyo ekubeni ikomiti nganye yezobuchwephesha inomelo kuzo zonke iiKomiti zeSizwe ezinomdla.

3) Ushicilelo lwe-IEC lunohlobo lweengcebiso zokusetyenziswa kwilizwe jikelele kwaye zamkelwe ziiKomiti zeSizwe ze-IEC ngaloo ndlela. Ngelixa zonke iinzame ezifanelekileyo zisenziwa ukuqinisekisa ukuba umxholo wobugcisa we-IEC Publications uchanekile, i-IEC ayinakubekwa tyala ngendlela ezisetyenziswa ngayo okanye ngayo nayiphi na
ukutolikwa gwenxa nguye nawuphi na umsebenzisi wokugqibela.

4) Ukukhuthaza ukufaniswa kwamazwe aphesheya, iiKomiti zeSizwe ze-IEC zithembisa ukusebenzisa upapasho lwe-IEC ngokungafihlisiyo kangangoko kunako kupapasho lwabo lwesizwe nolwengingqi. Nakuphi na ukwahluka phakathi kwalo naluphi na upapasho lwe-IEC kunye nopapasho oluhambelanayo lwesizwe okanye lommandla luya kuboniswa ngokucacileyo kokugqibela.

5) I-IEC ngokwayo ayinikezeli nabuphi na ubungqina bokuvumelana. Amaqumrhu azimeleyo anikezela ngeenkonzo zokuvavanya ukuhambelana kwaye, kwezinye iindawo, ukufikelela kumanqaku e-IEC okuhambelana. I-IEC ayinaxanduva lwazo naziphi na iinkonzo ezenziwa ngamaziko emfundo azimeleyo.

6) Bonke abasebenzisi mabaqinisekise ukuba banalo uhlelo lwamva nje lolu papasho.

7) Akukho xanduva luya kunamathela kwi-IEC okanye kubalawuli bayo, abaqeshwa, abakhonzi okanye iiarhente kubandakanya iingcali ezizodwa kunye namalungu eekomiti zayo zobugcisa kunye neekomiti ze-IEC zeLizwe kukonzakala komntu, ukonakaliswa kwepropathi okanye omnye umonakalo nakowuphi na uhlobo, nokuba kungokungqalileyo okanye ngokungathanga ngqo, okanye iindleko (kubandakanywa nemirhumo yezomthetho) kunye neendleko ezivela kupapasho, ukusetyenziswa, okanye ukuthembela koluPapasho lwe-IEC okanye naluphi na upapasho lwe-IEC.

8) Kuthathelwa ingqalelo kwizalathiso eziqhelekileyo ezibonisiwe kolu papasho. Ukusetyenziswa kopapasho olukhankanyiweyo kubalulekile ekusetyenzisweni ngokuchanekileyo kolu papasho.

9) Kuthathelwa ingqalelo into yokuba ezinye zezinto zoluPapasho lwe-IEC zinokuba ngumxholo wamalungelo awodwa omenzi wechiza. I-IEC ayisayi kuthwala xanduva lokuchonga nawaphi na okanye onke amalungelo anjalo e-patent.

Umgangatho wamazwe e-IEC 61643-21 ulungisiwe yikomitana 37A: Iivolthi ezisezantsi zokukhusela izixhobo ezikhuselayo, zekomiti yezobuchwephesha ye-IEC 37: Ababanjiweyo.

Olu hlobo luhlanganisiweyo lwe-IEC 61643-21 luqulathe ushicilelo lokuqala (2000) [amaxwebhu 37A / 101 / FDIS kunye nama-37A / 104 / RVD], ukulungiswa kwawo 1 (2008) [amaxwebhu 37A / 200 / FDIS kunye nama-37A / 201 / RVD ], ukulungiswa kwayo 2 (2012) [amaxwebhu 37A / 236 / FDIS kunye ne-37A / 237 / RVD] kunye ne-corrigendum yayo kaMatshi 2001.

Umxholo wobugcisa ke ngoko uyafana nohlobo olusisiseko kunye nezilungiso zalo kwaye zilungiselelwe ukusetyenziswa lula komsebenzisi.

Inenombolo yohlelo 1.2.

Umgca othe nkqo kwimida ibonisa apho upapasho olusisiseko lutshintshwe khona ngezilungiso 1 no-2.

Ikomiti ithathe isigqibo sokuba imixholo yopapasho olusisiseko kunye nezilungiso zayo ziya kuhlala zingatshintshanga de kube ngumhla wozinzo oboniswe kwiwebhusayithi ye-IEC phantsi kwe "http://webstore.iec.ch" kwidatha enxulumene nopapasho oluthile. Ngalo mhla, upapasho luya kuba
Ukuqinisekisa kwakhona,
• urhoxile,
• kufakwe uhlelo oluhlaziyiweyo, okanye
• zilungisiwe.

INTSHAYELELO

Injongo yalo Mgangatho waMazwe ngaMazwe kukuchonga iimfuno zeeSecurity Protect Devices (SPDs) ezisetyenziselwa ukukhusela iinkqubo zonxibelelwano kunye nokusayina, umzekelo, idatha enevolthi ephantsi, ilizwi kunye neesekethe zealam. Zonke ezi nkqubo zinokuvezwa ziziphumo zombane kunye neziphene zomgca wombane, nokuba kukunxibelelana ngokuthe ngqo okanye ukwenziwa. Ezi ziphumo zinokuthi zixhomekeke kwinkqubo kwi-overvoltages okanye kwi-overcurrents okanye zombini, amanqanaba abo aphezulu ngokwaneleyo ukonzakalisa inkqubo. Ii-SPDs zenzelwe ukubonelela ngokukhusela ngokuchasene ne-overvoltages kunye ne-overcurrents ebangelwa ngumbane kunye neempazamo zomgca wamandla. Lo mgangatho
ichaza iimvavanyo neemfuno ezimisela iindlela zokuvavanya ii-SPD kunye nokumisela ukusebenza kwazo.

Ii-SPDs ezibhekiswe kulo mgangatho wamanye amazwe zinokuba nezinto zokukhusela i-overvoltage kuphela, okanye indibaniselwano yezinto ezibalekayo kunye nezinto ezikhuselekileyo zokukhusela. Izixhobo zokhuselo eziqukethe izinto ezikhuselekileyo zokukhusela kuphela azikho ngaphakathi kulo mgangatho. Nangona kunjalo, izixhobo ezinamacandelo okhuselo agqithisiweyo zigutyungelwe kwisihlomelo A.

I-SPD inokuthi iqulethe izinto ezininzi zokukhusela kunye nokukhuselwa okugqithisileyo. Zonke ii-SPD zivavanywa kwi "ibhokisi emnyama", okt, inani leetheminali ze-SPD limisela inkqubo yovavanyo, hayi inani lezinto kwi-SPD. Ukucwangciswa kwe-SPD kuchaziwe kwi-1.2. Kwimeko yee-SPDs zemigca emininzi, umgca ngamnye unokuvavanywa ngokuzimeleyo kwabanye, kodwa kunokubakho isidingo sokuvavanya yonke imigca ngaxeshanye.

Lo mgangatho ugubungela uluhlu olubanzi lweemeko zovavanyo kunye neemfuno; ukusetyenziswa kwezinye zezi kukuqonda komsebenzisi. Zichaza njani iimfuno zalo mgangatho kwiindidi ezahlukeneyo ze-SPD ezichazwe kwi-1.3. Ngelixa oku kungumgangatho wentsebenzo kwaye amandla athile afunwayo kwii-SPDs, amaqondo okusilela kunye nokutolikwa kwawo kushiyelwe umsebenzisi. Imigaqo yokukhetha kunye nokusetyenziswa igutyungelwe kwi-IEC 61643-22.

Ukuba i-SPD yaziwa njengesixhobo esinye secandelo, kufuneka ihlangabezane neemfuno zomgangatho ofanelekileyo kunye nale ikulo mgangatho.
