Thwebula Khulula IEC 61643-11
I-FOREWORD
1) IKhomishini ye-International Electrotechnical Commission (IEC) yinhlangano yemhlaba wonkhe yekwenta emazinga lafaka ekhatsi onkhe emakhomidi etebucwepheshe be-electrotechnical (emaKomidi eLive lonkhe e-IEC). Inhloso ye-IEC ukugqugquzela ukubambisana kwamazwe omhlaba kuyo yonke imibuzo ephathelene nokubekwa kwezinga elithile emkhakheni kagesi nowe-elekthronikhi. Kuze kube manje futhi ngaphezu kweminye imisebenzi, i-IEC ishicilela Amazinga Womhlaba Wonke, Ukucaciswa Kwezobuchwepheshe, Imibiko Yezobuchwepheshe, Ukucaciswa Kutholakala Esidlangalaleni (PAS) kanye namaGuides (ngemuva kwalokhu abizwa nge- “Publication (s) IEC”). Ukulungiselela kwabo kunikezwe amakomidi ezobuchwepheshe; noma yiliphi iKomidi Likazwelonke le-IEC elinentshisekelo esihlokweni okukhulunywa ngaso lingahlanganyela kulo msebenzi wokulungiselela. Izinhlangano zomhlaba wonke, ezikahulumeni kanye nezinhlangano ezingekho ngaphansi kukahulumeni ezixhumana ne-IEC nazo zibamba iqhaza kulokhu kulungiselela. I-IEC ibambisana kakhulu ne-International Organisation for Standardization (ISO) ngokuya ngezimo ezinqunywe ngesivumelwano phakathi kwalezi zinhlangano zombili.
2) Izinqumo ezisemthethweni noma izivumelwano ze-IEC ezindabeni zobuchwepheshe ziveza, cishe ngangokunokwenzeka, ukuvumelana kwemibono yamazwe omhlaba ngezihloko ezifanele njengoba ikomidi ngalinye lobuchwepheshe linokumelwa kuwo wonke amaKomidi Kazwelonke e-IEC anentshisekelo.
3) I-IEC Publications inesimo sezincomo zokusetshenziswa kwamazwe omhlaba futhi yamukelwa ngamaKomidi Kazwelonke e-IEC ngalowo mqondo. Yize yonke imizamo efanelekile yenziwa ukuqinisekisa ukuthi okuqukethwe kwezobuchwepheshe kwe-IEC Publications kunembile, i-IEC ayinakubekwa cala ngendlela ezisetshenziswa ngayo
ukuhumusha kabi nganoma imuphi umsebenzisi.
4) Ukuze kukhuthazwe ukufana kwamazwe omhlaba, amaKomidi Kazwelonke e-IEC athembisa ukusebenzisa i-IEC Publications ngokusobala ngezinga eliphezulu kakhulu ekushicilelweni kwawo kuzwelonke kanye nasezifundeni. Noma ikuphi ukwehluka phakathi kwanoma yikuphi ukushicilelwa kwe-IEC nokushicilelwa okuhambisanayo kukazwelonke noma kwesifunda kuzokhonjiswa ngokusobala kokugcina.
I-5) I-IEC uqobo ayinikezeli ubufakazi bokuvumelana. Imigwamanda ezimele yokunikeza izitifiketi inikela ngezinsizakalo zokuhlola ukuhambisana nokuthi, kwezinye izindawo, ukufinyelela kumamaki wokuhambisana kwe-IEC. I-IEC ayinasibopho sanoma yiziphi izinsizakalo ezenziwa yizinhlangano ezizimele zezitifiketi.
6) Bonke abasebenzisi kumele baqinisekise ukuthi banalo uhlelo lwakamuva lwale ncwadi.
7) Asikho isikweletu esizonamathisela i-IEC noma abaqondisi bayo, abasebenzi, izisebenzi noma abenzeli kubandakanya ongoti ngazinye namalungu amakomidi ayo ezobuchwepheshe kanye namaKomidi Kazwelonke e-IEC ngokulimala komuntu siqu, ukulinyazwa kwempahla noma omunye umonakalo wanoma iluphi uhlobo, kungakhathaliseki ukuthi luqondile noma aluqondile, noma izindleko (kufaka phakathi imali yezomthetho) nezindleko ezivela ekushicilelweni, ukusetshenziswa, noma ukuthembela kulo, Ukushicilelwa kwe-IEC noma okunye okushicilelwe yi-IEC.
8) Kudonselwa ukunakekelwa kuzinkomba ezijwayelekile ezibalulwe kule ncwadi. Ukusetshenziswa kwemibhalo ekhonjisiwe kubaluleke kakhulu ekusetshenzisweni okulungile kwalokhu kushicilelwa.
I-9) Kudonswa ukunakekelwa kokuthi kungenzeka ukuthi ezinye zezinto zalokhu Kushicilelwa kwe-IEC kungaba yindaba yamalungelo obunikazi. I-IEC ngeke ibe necala lokuthola noma yimaphi amalungelo noma amalungelo obunikazi anjalo.
I-International Standard IEC 61643-11 seyilungiswe yi-subcommittee 37A: I-low-voltage surges amadivayisi wokuvikela, we-IEC technical committee 37: Surge arresters.
Lolu hlobo lokuqala lwe-IEC 61643-11 lukhansela futhi lubeka esikhundleni i-IEC 61643-1 yesibili eyashicilelwa ngo-2005. Lolu hlobo lwenziwa ukubukeza kwezobuchwepheshe.
Izinguquko ezinkulu maqondana nohlelo lwesibili lwe-IEC 61643-1 ukulungiswa kabusha okuphelele kanye nokwenza ngcono izinqubo zokuhlola nokulandelana kokuhlolwa.
Umbhalo waleli zinga usekelwe kumadokhumenti alandelayo:
I-FDIS: 37A / 229 / FDIS
Bika ngokuvota: 37A / 232 / RVD
Imininingwane ephelele ngokuvotelwa kokuvunywa kwaleli zinga ingatholakala embikweni wokuvota okhonjiswe etafuleni elingenhla.
Lokhu kushicilelwa kubhalwe ngokuya ngemiyalo ye-ISO / IEC, Ingxenye 2.
Uhlu lwazo zonke izingxenye zochungechunge lwe-IEC 61643 lungatholakala, ngaphansi kwesihloko esijwayelekile samadivayisi wokuvikela amandla aphansi, kuwebhusayithi ye-IEC.
Ikomidi linqume ukuthi okuqukethwe yilo shicilelo kuzohlala kungashintshiwe kuze kube usuku lokuzinza olukhonjiswe kuwebhusayithi ye-IEC ngaphansi kwe- “http://webstore.iec.ch” emininingwaneni ephathelene nokushicilelwa okuthile. Ngalesi sikhathi, ukushicilelwa kuzoba
- kuqinisekisiwe,
- kuhoxisiwe,
- indawo yenguqulo ebukeziwe, noma
- kuchitshiyelwe.
QAPHELA Ukunakwa kwamaKomidi Kazwelonke kudonselwa eqinisweni lokuthi abakhiqizi bezinto zokusebenza kanye nezinhlangano zokuhlola zingadinga isikhathi soguquko ngemuva kokushicilelwa kwesikhangiso esisha, esichitshiyelwe noma esibuyekeziwe se-IEC lapho kuzokwenziwa khona imikhiqizo ngokuya ngezidingo ezintsha nokuzihlomisa ngokuqhuba izivivinyo ezintsha noma ezibuyekeziwe.
Kuyisincomo sekomidi ukuthi okuqukethwe yilokhu kushicilelwa kwamukelwe kuzwelonke
ukwenziwa kungakadluli izinyanga eziyi-12 kusukela ngosuku lokushicilelwa.
ISINGENISO
Le ngxenye ye-IEC 61643 ikhuluma ngokuhlolwa kokuphepha nokusebenza kwamadivayisi wokuvikela ama-surge (SPDs).
Kunezigaba ezintathu zezivivinyo:
Isivivinyo se-Class I senzelwe ukulingisa imicabango yamanje eyenziwe ngombani. Ama-SPD anikezwe ngaphansi kwezindlela zokuhlola ze-Class I ngokuvamile anconyelwa izindawo ezindaweni zokuvezwa okuphezulu, isb. Ukungena komugqa ezakhiweni ezivikelwe yizinhlelo zokuvikela umbani.
Ama-SPD ahlolwe kuzindlela zokuhlola ze-Class II noma III abhekene nemicabango yesikhathi esifushane.
Ama-SPD ahlolwa ngesisekelo se "black box" ngangokunokwenzeka.
I-IEC 61643-12 ikhuluma ngemigomo yokukhethwa nokusetshenziswa kwama-SPD ezimweni ezisebenzayo.
