EN 61643-11 & IEC 61643-21: 2012 Zida zotetezera zamagetsi zamagetsi otsika - Gawo 21: Zipangizo zowonjezera zotetezedwa zolumikizidwa ndi ma telefoni ndi ma signature maukonde - Zoyenera kuchita ndi njira zoyesera

ONANI

1) International Electrotechnical Commission (IEC) ndi bungwe lapadziko lonse lapansi lokhazikika lomwe lili ndi makomiti onse amagetsi (IEC National Committee). Cholinga cha IEC ndikulimbikitsa mgwirizano wapadziko lonse pamafunso onse okhudzana ndi kukhazikika pamagetsi zamagetsi ndi zamagetsi. Kuti izi zitheke komanso kuwonjezera pazinthu zina, IEC imafalitsa Miyezo Yapadziko Lonse, Maukadaulo Aumisiri, Malipoti Aumisiri, Zambiri Pagulu (PAS) ndi Maupangiri (omwe pambuyo pake amatchedwa "Kufalitsa kwa IEC"). Kukonzekera kwawo kumaperekedwa kumakomiti aluso; Komiti Yadziko Lonse ya IEC yomwe ikukhudzidwa ndi nkhaniyi ikhoza kutenga nawo mbali pantchito yokonzekerayi. Mabungwe apadziko lonse lapansi, aboma komanso omwe siaboma omwe amalumikizana ndi IEC nawonso amatenga nawo mbali pokonzekera izi. IEC imagwira ntchito limodzi ndi International Organisation for Standardization (ISO) malinga ndi zomwe zatsimikiziridwa ndi mgwirizano pakati pa mabungwe awiriwa.

2) Zisankho kapena mapangano amtundu wa IEC pankhani zaluso amafotokoza, pafupifupi momwe zingathere, mgwirizano wapadziko lonse lapansi pamitu yoyenera popeza komiti iliyonse yaumisiri ili ndi chiwonetsero kuchokera ku Makomiti onse a IEC.

3) Zofalitsa za IEC zili ndi malingaliro othandizira ntchito yapadziko lonse lapansi ndipo zimalandiridwa ndi Makomiti Amayiko a IEC mwanjira imeneyi. Ngakhale zoyesayesa zonse zikuchitika kuti zitsimikizire kuti luso la IEC Publications ndilolondola, IEC silingakhale ndi mlandu chifukwa chogwiritsa ntchito kapena china chilichonse
kutanthauzira kolakwika ndi aliyense wogwiritsa ntchito kumapeto.

4) Pofuna kulimbikitsa kufanana kwapadziko lonse lapansi, Ma komiti Amayiko a IEC akuyesetsa kuti agwiritse ntchito zofalitsa za IEC mosabisa momwe angathere pazofalitsa zawo zadziko ndi zigawo. Kusiyanitsa kulikonse pakati pa Kutulutsa kulikonse kwa IEC ndi kufalitsa kofananira kwa dziko lonse kapena chigawo kudzafotokozedwa momveka bwino kumapeto kwake.

5) IEC palokha siyopereka umboni uliwonse wotsatizana. Mabungwe odziyimira pawokha amapereka ntchito zowunika kutsata ndipo, m'malo ena, mwayi wopeza ma IEC kutsatira. IEC siyiyang'anira ntchito iliyonse yochitidwa ndi mabungwe odziyimira pawokha.

6) Ogwiritsa ntchito onse akuyenera kuwonetsetsa kuti ali ndi mtundu watsopanowu.

7) Palibe udindo uliwonse womwe ungagwirizane ndi IEC kapena owongolera, ogwira ntchito, ogwira ntchito kapena othandizira kuphatikiza akatswiri ndi mamembala am'makomiti ake aumisiri ndi Makomiti Amayiko a IEC pazovulala zilizonse, kuwonongeka kwa katundu kapena kuwonongeka kwa mtundu wina uliwonse, kaya mwachindunji kapena mwachindunji, kapena zolipirira (kuphatikiza chindapusa) ndi ndalama zomwe zatuluka pakufalitsa, kugwiritsa ntchito, kapena kudalira, Kufalitsa kwa IEC uku kapena Zofalitsa zilizonse za IEC.

8) Kuyang'aniridwa ndikulongosola zomwe zatchulidwa m'buku lino. Kugwiritsa ntchito zofotokozedwazo ndikofunikira kwambiri kuti bukuli ligwiritsidwe ntchito moyenera.

9) Kuyang'aniridwa kuti kuthekera kuti zina mwazinthu zofalitsa za IEC izi zitha kukhala ufulu wa patent. IEC sidzakhala ndi mlandu wodziwitsa ufulu uliwonse wa umwiniwu.

International Standard IEC 61643-21 idakonzedwa ndi subcommittee 37A: Low-voltagesurge zida zoteteza, za IEC technical committee 37: Surge arresters.

Mtundu wophatikizidwa wa IEC 61643-21 uli ndi mtundu woyamba (2000) [zikalata 37A / 101 / FDIS ndi 37A / 104 / RVD], kusintha kwake 1 (2008) [zikalata 37A / 200 / FDIS ndi 37A / 201 / RVD ], kusintha kwake 2 (2012) [zikalata 37A / 236 / FDIS ndi 37A / 237 / RVD] ndi corrigendum yake ya Marichi 2001.

Zomwe zili muukadaulo ndizofanana ndi mtundu woyambira ndi zosintha zake ndipo zakonzedwa kuti zitheke kwa ogwiritsa ntchito.

Ili ndi nambala ya 1.2.

Mzere wowongoka m'mphepete mwake umawonetsa pomwe kufalitsa koyambira kwasinthidwa ndikusintha 1 ndi 2.

Komitiyi yaganiza kuti zomwe zalembedwazo komanso zomwe zasinthidwa zisasinthidwe mpaka tsiku lokhazikika lomwe latsimikizidwa patsamba la IEC pansi pa "http://webstore.iec.ch" muzochitika zokhudzana ndi kufalitsa kumeneku. Pakadali pano, kufalitsa kudzakhala
Adatsimikiziranso,
• kudzipatula,
• m'malo mwake mwatulutsidwa buku lokonzedwanso, kapena
• kusinthidwa.

MAU OYAMBA

Cholinga cha International Standard ichi ndikuzindikira zofunikira za Surge Protective Devices (SPDs) zomwe zimagwiritsidwa ntchito poteteza ma telecommunication ndi ma signature, mwachitsanzo, ma voliyumu otsika, mawu, ndi ma alarm. Machitidwe onsewa amatha kuwonetsedwa ndi zotsatira za mphezi ndi zolakwika zamagetsi, mwina kudzera kulumikizana mwachindunji kapena kulowetsedwa. Zotsatirazi zitha kupangitsa kuti dongosololi likhale lopitilira muyeso kapena kupitilira apo kapena zonse ziwiri, zomwe milingo yake ndiyokwanila kuwononga dongosololi. Ma SPD amalinganizidwa kuti ateteze ku mayendedwe am'madzi omwe amapezeka chifukwa cha mphezi komanso zolakwika zamagetsi. Mulingo uwu
imalongosola mayeso ndi zofunikira zomwe zimakhazikitsa njira zoyesera ma SPD ndikuzindikira momwe amagwirira ntchito.

Ma SPD omwe adafotokozedwera mu International Standard atha kukhala ndi zida zodzitchinjiriza zokha, kapena kuphatikiza kwa zida zopitilira muyeso ndi zotetezera mopitirira muyeso. Zipangizo zodzitetezera zomwe zimakhala ndi zida zodzitetezera mopitilira muyeso sizili muyezo uwu. Komabe, zida zokhala ndi zida zodzitetezera mopitilira muyeso zimaphimbidwa mu cholumikizira A.

SPD imatha kukhala ndi zida zingapo zotetezera komanso zotetezera mopitirira muyeso. Ma SPD onse amayesedwa pa "bokosi lakuda", mwachitsanzo, kuchuluka kwama terminals a SPD kumatsimikizira njira yoyesera, osati kuchuluka kwa zinthu mu SPD. Makonda a SPD amafotokozedwa mu 1.2. Pankhani yama SPD angapo, mzere uliwonse ukhoza kuyesedwa mosadalira ena, koma pangafunikenso kuyesa mizere yonse nthawi imodzi.

Mulingo uwu umakhudza zochitika zosiyanasiyana zoyesa ndi zofunikira; kugwiritsa ntchito zina mwazo ndikuzindikira kwa wogwiritsa ntchito. Momwe zofunikira pamiyeso iyi zimakhudzira mitundu yosiyanasiyana ya SPD ikufotokozedwa mu 1.3. Pomwe ili ndi muyezo wa magwiridwe antchito ndipo kuthekera kwina kumafunsidwa ndi ma SPD, mitengo yakulephera ndikutanthauzira kwawo imasiyidwa kwa wogwiritsa ntchito. Kusankha ndi kugwiritsa ntchito mfundozi zalembedwa mu IEC 61643-22.

Ngati SPD imadziwika kuti ndi chinthu chimodzi, imayenera kukwaniritsa zofunikira muyezo womwewo.
