1) ʻO ka International Electrotechnical Commission (IEC) kahi hui honua no ka standardization piha i nā komite electrotechnical āpau (IEC National Committees). ʻO ka mea o ka IEC e hoʻolaha i ka launa pū ʻana o ka honua ma nā nīnau āpau e pili ana i ka maʻamau ʻana i ka uila a me nā uila. I kēia hopena a me ka hoʻohui ʻana i nā hana ʻē aʻe, hoʻolaha ʻo IEC i nā Kānāwai International, nā kikoʻī kikoʻī, nā hōʻike loea, nā hoʻolaha i loaʻa ākea (PAS) a me nā alakaʻi (ma hope aku ua kapa ʻia ʻo "IEC Publication (s)"). Hāʻawi ʻia kā lākou hoʻomākaukau i nā kōmike ʻenehana; i kekahi Komite Lahui IEC hoihoi i ke kumuhana i hana ʻia e komo i kēia hana hoʻomākaukau. ʻO nā hui kaiaulu, aupuni a me nā aupuni nongovernmental e launa pū me ka IEC e komo pū i kēia hoʻomākaukau. Hana pū ʻo IEC me ka International Organization for Standardization (ISO) e like me nā ʻōlelo i hoʻoholo ʻia e ka ʻaelike ma waena o nā hui ʻelua.

2) Hōʻike nā ʻōlelo hoʻoholo a ʻaelike paha o ka IEC e pili ana i nā mea loea, i kahi hiki ke hiki, kahi ʻae kūwaho o ka manaʻo o ka honua e pili ana i nā kumuhana pili mai ka manawa o kēlā me kēia kōmike loea e hōʻike nei i nā Kōmike National IEC āpau.

3) Loaʻa nā hoʻolaha IEC i nā ʻano ʻōlelo aʻoaʻo no ka hoʻohana ʻana o ka honua a ʻae ʻia e nā Kōmike Lahui IEC ma ia ʻano. ʻOiai nā hana kūpono āpau e hōʻoia i ka ʻike ʻenehana o ka IEC Publications he pololei, ʻaʻole hiki i IEC ke kuleana no ke ʻano o ka hoʻohana a i ʻole no kekahi.
kuhi hewa ʻana e kekahi mea hoʻohana hope.

4) I mea e paipai ai i ka laulima kūwaho, mālama nā Kōmike Lahui IEC e hoʻopili pono i nā hoʻolaha IEC i ka nui loa i hiki i kā lākou puke pai ʻāina a ʻāpana hoʻi. ʻO kēlā me kēia ʻokoʻa ma waena o kekahi IEC Publication a me ka paʻi kūloko a kūloko paha e hōʻike pono ʻia i ka hope.

5) ʻAʻole hoʻolako ʻo IEC ponoʻī i kekahi hōʻike o ke kūlike. Hāʻawi nā kino hōʻoia kūʻokoʻa i nā lawelawe loiloi kūlike a, i kekahi mau wahi, ke kiʻi i nā kaha IEC o ke kūlike. ʻAʻohe o IEC kuleana no nā lawelawe i hoʻokō ʻia e nā kino hōʻoia hōʻoia kūʻokoʻa.

6) Pono nā mea hoʻohana āpau e hōʻoia iā lākou ka mana hou o kēia paʻi.

7) ʻAʻole pili kekahi kuleana i ka IEC a i ʻole kona mau alakaʻi, nā limahana, nā kauā a me nā ʻākena e like me nā poʻe loea a me nā lālā o kāna mau kōmike ʻenehana a me nā Kōmike Lahui IEC no kekahi ʻeha pilikino, ʻino waiwai a i ʻole nā ​​hōʻino ʻē aʻe o kēlā me kēia ʻano, inā pololei a pololei ʻole paha. a i ʻole no nā koina (me nā uku loio) a me nā lilo e puka aʻe ana mai ka paʻi ʻana, hoʻohana ʻana, a i ʻole ka paulele ʻana i kēia IEC Publication a i ʻole nā ​​hoʻolaha IEC ʻē aʻe.

8) Nānā ʻia ka nānā i nā kūmole Normative i ʻōlelo ʻia i loko o kēia paʻi. Pono ʻole ka hoʻohana ʻana o nā paʻi i kuhikuhi ʻia no ka noi pololei o kēia paʻi.

9) Nānā ʻia ka nānā ʻana i ka hiki i kekahi o nā mea o kēia IEC Publication ke kumuhana o nā kuleana patent. ʻAʻole e kuleana ʻo IEC no ka ʻike ʻana i kekahi a i ʻole nā ​​kuleana pili i kēlā me kēia.

Ua hoʻomākaukau ʻia ka International Standard IEC 61643-21 e ka kōmike kōmike 37A: nā mea pale pale haʻahaʻa me nā voltagesurge, o ke kōmike ʻenehana IEC 37: nā mea hopu pio.

ʻO kēia mana i hoʻohui ʻia o IEC 61643-21 kahi o ka paʻi mua (2000) [nā palapala 37A / 101 / FDIS a me 37A / 104 / RVD], kona hoʻololi 1 (2008) [palapala 37A / 200 / FDIS a me 37A / 201 / RVD ], kona hoʻololi 2 (2012) [palapala 37A / 236 / FDIS a me 37A / 237 / RVD] a me kāna corrigendum o Malaki 2001.

No laila like ka ʻenehana i ka hoʻopuka kumu a me kāna mau hoʻoponopono a hoʻomākaukau ʻia no ka pono o ka mea hoʻohana.

Hāpai ia i ka helu edition 1.2.

Hōʻike kahi laina kū i ka palena ma kahi i hoʻololi ʻia ai ka paʻi kumu e nā hoʻoponopono 1 a me 2.

Ua hoʻoholo ke kōmike e noho mau nā mea o ka hoʻopuka kumu a me kāna mau hoʻoponopono a hiki i ka lā paʻa i hōʻike ʻia ma ka pūnaewele IEC ma lalo o "http://webstore.iec.ch" i ka ʻikepili e pili ana i ka paʻi kikoʻī. I kēia lā, e hoʻolaha ʻia ka hoʻolaha ʻana
• hōʻoia hou ʻia,
Huki ʻia
• pani ʻia e ka paʻi hou, a i ʻole

Introduction

ʻO ke kumu o kēia International Standard e hoʻomaopopo i nā koi no Surge Protective Devices (SPD) i hoʻohana ʻia i ka pale ʻana i nā ʻōnaehana kelekiko a me nā ʻōnaehana hōʻailona, ​​no ka laʻana, ka ʻikepili uila haʻahaʻa, ka leo, a me nā kaʻa kaʻa kaʻa. Hōʻike ʻia paha kēia mau ʻōnaehana āpau i nā hopena o ka uila a me nā hewa o ka laina uila, ma o ka hoʻopili pololei ʻana a i ʻole ka hoʻokomo ʻana. Hoʻopili paha kēia mau hopena i ka ʻōnaehana i nā overvoltages a i ʻole overcurrents a i ʻole ʻelua, nona nā pae i lawa ke kiʻekiʻe e hōʻino ai i ka ʻōnaehana. Manaʻo ʻia ʻo SPDs e pale aku i nā overvoltages a me nā overcurrents i hoʻokumu ʻia e nā uila a me nā hewa o ka laina mana. Kēia hae
wehewehe i nā hoʻokolohua a me nā koi e hoʻokumu i nā ʻano hana no ka hoʻāʻo ʻana i nā SPD a me ka hoʻoholo ʻana i kā lākou hana.

Hiki i nā SPD ke kamaʻilio ʻia i loko o kēia International Standard ke loaʻa nā ʻāpana pale overvoltage wale nō, a i ʻole ka hui ʻana o ka overvoltage a me nā ʻaoʻao pale overcurrent. ʻO nā hāmeʻa pale i loaʻa nā ʻaoʻao pale overcurrent wale nō ʻaʻole i loko o ka uhi o kēia maʻamau. Eia nō naʻe, uhi ʻia nā hāmeʻa me nā mea pale pale overcurrent wale nō i ka hoʻohui ʻāina A.

Hiki i kahi SPD ke komo i kekahi mau overvoltage a me nā mea pale overcurrent. Hōʻaʻo ʻia nā SPD āpau ma ke kumu o ka "pahu ʻeleʻele", ʻo ia hoʻi, ʻo ka helu o nā terminals o ka SPD e hoʻoholo i ke kaʻina hoʻokolohua, ʻaʻole ka helu o nā mea i ka SPD. Hōʻike ʻia nā hoʻonohonoho SPD i 1.2. I ka hihia o nā laina SPD he nui, e hoʻāʻo kūʻokoʻa ʻia kēlā me kēia laina o nā mea ʻē aʻe, akā aia paha kahi pono e hoʻāʻo i nā laina āpau i ka manawa like.

Uhi kēia maʻamau i ka laulā o nā kūlana hoʻāʻo a me nā koi; ka hoʻohana ʻana o kekahi o kēia mau mea i ka manaʻo o ka mea hoʻohana. Pehea e pili ai nā koi o kēia maʻamau i nā ʻano ʻokoʻa o SPD i ka 1.3. ʻOiai he kūlana hana kēia a koi ʻia kekahi mau hiki i nā SPD, waiho ʻia nā helu holomua a me kā lākou unuhi i ka mea hoʻohana. Uhi ʻia nā kulekele koho a me nā noi i IEC 61643-22.

Inā ʻike ʻia ka SPD kahi pono hana ʻokoʻa, pono ia e hoʻokō i nā koi o ke ana kūpono e like me nā mea i kēia kūlana.
