Mahara Kurodha IEC 61643-11
ZVEKUITA
1) International Electrotechnical Commission (IEC) isangano repasirese rekumisikidza rinosanganisira makomititi emagetsi emunyika (IEC Makomiti Enyika). Chinangwa cheIEC ndechekusimudzira kudyidzana kwepasi rose pamibvunzo yese ine chekuita nekumisikidzwa muminda yemagetsi nemagetsi. Kuti izvi zviitike uye kuwedzera kune zvimwe zviitiko, IEC inoburitsa International Standards, technical Specific, technical Reports, Ruzhinji Ruripo Ruzivo (PAS) uye maGuides (pano anotevera anonzi "IEC Kuburitswa (ma)"). Kugadzirira kwavo kwakapihwa kumakomiti ehunyanzvi; chero IEC National Committee inofarira nyaya inobatwa inogona kutora chikamu mune iri basa rekugadzirira. Masangano epasi rose, ehurumende uye asiri ehurumende anobatana neIEC vanoitawo gadziriro iyi. IEC inoshanda pamwe neInternational Organisation for Standardization (ISO) maringe nemitemo yakatemwa nechibvumirano pakati pemasangano maviri aya.
2) Sarudzo dzepamutemo kana zvibvumirano zveIEC pazvinhu zvehunyanzvi zvinoratidzira, sezvinobvira, kubvumirana kwepasi rose kwemaonero pazvinhu zvakakodzera sezvo komiti yega yega yeumiriri inomiririrwa kubva kune vese vanofarira maIEC Makomiti eNyika.
3) IEC Mabhuku ane fomu yemazano ekushandiswa kwepasi rose uye anotambirwa neIEC maNational Committees nenzira iyoyo. Kunyange kuedza kwese kunoitwa kunoitwa kuve nechokwadi chekuti zvemukati meIEC Mabhuku ari echokwadi, IEC haigone kuve nemhosva nemashandisirwo avari kuitwa kana chero
kududzirwa zvisiri izvo nemumwe mugumo-mushandisi.
4) Kuti ikwidziridze kufanana kwenyika dzese, maIEC MaKomiti eNyika anozvipira kushandisa IEC Mabudiro pachena pachena kusvika pazvinogoneka mumabhuku avo emunyika nemudunhu. Chero kupesana pakati pechero IEC Kuburitswa uye inoenderana yenyika kana yedunhu kuburitswa ichanyatsoratidzwa mune yekupedzisira.
5) IEC pachayo haipe chero humbowo hwekuenderana. Masangano akazvimirira ekuzvipa anopa kuenderana kwekuongorora masevhisi uye, mune dzimwe nzvimbo, kuwana maIEC mamaki ekuenderana. IEC haina mutoro kune chero masevhisi anoitwa nemasangano akazvimiririra ekuzivisa.
6) Vese vashandisi vanofanirwa kuona kuti vane yazvino vhezheni yechinyorwa chino.
7) Hapana chikwereti chinosungirirwa kuIEC kana madhairekitori, vashandi, vashandi kana vamiririri vanosanganisira nyanzvi dzega uye nhengo dzemakomiti ayo ehunyanzvi uye maIEC MaKomiti Enyika ekukuvara kweumwe neumwe, kukuvara kwepfuma kana kumwe kukuvara kwechero chinhu chipi zvacho, chingave chakanangana kana chisina kunangana, kana pamitengo (inosanganisira mari yepamutemo) nemari inoshandiswa kubva mukuburitswa, kushandiswa, kana kuvimba, neIEC Publication iyi kana chero rimwe bhuku reIEC.
8) Kucherechedzwa kunoitwa kune zvinowanzoitika mareferenzi akataurwa mubhuku rino. Iko kushandiswa kwezvinyorwa zvakadomwa kwakakosha mukushandisa chaiko kwechinyorwa chino.
9) Kucherechedzwa kunokwezverwa kune mukana wekuti zvimwe zvezvinhu zveiyi IEC Kuburitswa zvinogona kunge zviri nyaya yekodzero dzepamutemo. IEC haizovi nemhosva yekuona chero kana chero kodzero dzakadaro dzepamutemo.
International Standard IEC 61643-11 yakagadzirirwa ne subcommittee 37A: Yakadzika-voltage surges inodzivirira michina, yeIEC technical committee 37: Surge vanosungwa.
Iyi yekutanga edition yeIEC 61643-11 inodzima uye inotsiva yechipiri edition yeIEC 61643-1 yakaburitswa muna 2005. Iyi shanduro inoita tekinoroji kudzokorora.
Shanduko huru zvine chekuita neshanduro yechipiri yeIEC 61643-1 ndiko kugadzirisa patsva uye kugadzirisa kwemaitiro ebvunzo uye kuteedzana kwekuyedza.
Chinyorwa cheichi chiyero chakavakirwa pane anotevera magwaro:
FDIS: 37A / 229 / FDIS
Chirevo chekuvhota: 37A / 232 / RVD
Ruzivo rwakazara pamusoro pekuvhota kwekubvumidzwa kwechiyero ichi kunogona kuwanikwa mumushumo wekuvhota unoratidzwa mune tafura iri pamusoro.
Chinyorwa ichi chakanyorwa zvinoenderana neiyo ISO / IEC Mirairo, Chikamu 2.
Rondedzero yezvikamu zvese zveIEC 61643 akateedzana anogona kuwanikwa, pasi pezita rakanzi Low-voltage surge zvidziviriro, pane webhusaiti yeIEC.
Dare rakafunga kuti zvirimo mubhuku iri zvinoramba zvisina kuchinja kudzamara zuva rerunyararo raratidzwa pawebhusaiti yeIEC pasi pe "http://webstore.iec.ch" mune data rine chekuita nechinyorwa chakatsanangurwa. Parizvino, chinyorwa chichava
- kusimbiswazve,
- kubviswa,
- yakatsiviwa neshanduro yakadzokororwa, kana
- yakagadziridzwa.
ONA Kutarisisa kweMakomiti eNyika kunokweverwa kuchokwadi chekuti vagadziri vemidziyo nemasangano ekuyedza vangangoda nguva yekuchinja zvichitevera kuburitswa kwechinyorwa chitsva, chakagadziridzwa kana chakagadziridzwa cheIEC umo kugadzira zvigadzirwa zvinoenderana nezvinodiwa zvitsva uye kuzvishongedza kuitisa mitsva kana kuongororwa.
Iko kurudziro yekomiti kuti zvinyorwa zvebhuku rino zvitambirwe nyika
kuitiswa kwete pamberi pemwedzi gumi nembiri kubva pazuva rekuburitswa.
NHANGANYAYA
Iyi chikamu cheIEC 61643 inotarisa kuchengetedzeka uye kuita kwekuyedza kwemidziyo yekudzivirira (SPDs).
Kune makirasi matatu ebvunzo:
Iyo Kirasi I bvunzo inoitirwa kutevedzera yakasarudzika inoitiswa mheni mafambiro azvino. MaSPD anoiswa kuClass I nzira dzekuyedza dzinowanzo kurudzirwa kunzvimbo dziri panzvimbo dzekuratidzira kwakanyanya, semuenzaniso, masuo ekupinda muzvivakwa zvakachengetedzwa nemagetsi ekudzivirira masisitimu.
SPDs yakaedzwa kuClass II kana III nzira dzekuyedza dzinoiswa mukuda kwenguva pfupi.
MaSPD anoedzwa pane "nhema bhokisi" hwaro sezvazvinogona.
IEC 61643-12 inotaura nezvekusarudzwa uye maitiro ekushandisa ePSD mumamiriro ezvinhu anoshanda.
