Kutanthauzira Kwatsatanetsatane pa IEC 62133: 2017 + AMD1: 2021 (kope 1.1),
CB,

▍KodiCBChitsimikizo?

IECEECBndi njira yoyamba yapadziko lonse lapansi yovomerezera malipoti oyesa chitetezo cha zida zamagetsi. NCB (National Certification Body) ifika pa mgwirizano wamayiko osiyanasiyana, womwe umathandizira opanga kuti apeze ziphaso zadziko kuchokera kumayiko ena omwe ali mamembala pansi pa dongosolo la CB potengera kusamutsa chimodzi mwa ziphaso za NCB.

Satifiketi ya CB ndi chikalata chovomerezeka cha CB choperekedwa ndi NCB yovomerezeka, chomwe ndikudziwitsa NCB ina kuti zitsanzo zazinthu zoyesedwa zikugwirizana ndi zomwe zikufunika.

Monga mtundu wa lipoti lokhazikika, lipoti la CB limalemba zofunikira kuchokera ku IEC wamba ndi chinthu. Lipoti la CB silimangopereka zotsatira za mayeso onse ofunikira, kuyeza, kutsimikizira, kuyang'anira ndi kuwunika momveka bwino komanso mosadziwika bwino, komanso kuphatikiza zithunzi, chithunzi chozungulira, zithunzi ndi malongosoledwe azinthu. Malinga ndi lamulo la CB scheme, lipoti la CB siligwira ntchito mpaka litapereka satifiketi ya CB palimodzi.

▍Nchifukwa chiyani timafunikira CB Certification?

1. Chindunjilykuzindikirazedi or kuvomerezaedmwamembalamayiko

Ndi satifiketi ya CB ndi lipoti la mayeso a CB, malonda anu amatha kutumizidwa kumayiko ena mwachindunji.

1. Sinthani kumayiko ena ziphaso

Satifiketi ya CB imatha kusinthidwa mwachindunji kukhala satifiketi ya mayiko omwe ali mamembala ake, popereka satifiketi ya CB, lipoti la mayeso ndi lipoti loyesa kusiyana (ngati kuli kotheka) osabwereza mayeso, omwe angafupikitse nthawi yotsogolera yotsimikizira.

1. Onetsetsani Chitetezo cha Zamalonda

Mayeso a certification a CB amawona kugwiritsidwa ntchito moyenera kwa chinthucho komanso chitetezo chodziwikiratu chikagwiritsidwa ntchito molakwika. Chitsimikizo chotsimikizika chimatsimikizira zokhutiritsa zofunikira zachitetezo.

▍Chifukwa chiyani MCM?

● Ziyeneretso:MCM ndiye CBTL yoyamba yovomerezeka ya IEC 62133 yovomerezeka ndi TUV RH ku China.

● Chitsimikizo ndi kuthekera koyesa:MCM ili m'gulu loyamba loyesa ndi kutsimikizira chipani chachitatu pa muyezo wa IEC62133, ndipo yamaliza kuyesa kwa batri 7000 IEC62133 ndi malipoti a CB kwa makasitomala apadziko lonse lapansi.

● Thandizo laukadaulo:MCM ili ndi akatswiri opitilira 15 odziwika bwino pakuyesa malinga ndi muyezo wa IEC 62133. MCM imapatsa makasitomala chithandizo chokwanira, cholondola, chotsekeka chaukadaulo komanso zidziwitso zotsogola.

【Chidule cha Standard Revision】
Mulingo uwu ndi mtundu wophatikiza wa IEC 62133: 2017 ndi AMD1: 2021, makamaka wokhudza magawo anayi owunikiridwa (onani mwatsatanetsatane zomwe zasinthidwa mwatsatanetsatane). Ndi zambiri za kukwanira kwa muyezo wapachiyambi, palibe kukonzanso kwaukadaulo kwambiri, chifukwa chake, sikungakhudze kuthekera koyesa. Koma kusintha kwa mawu ena oyesera kungakhudze zotsatira zoyesa.
【Zosinthidwanso】
1, 7.1.2: Kuwunikiridwanso kwa njira yolipirira: osagwiritsa ntchito kukonzanso pamagetsi odulidwa
ya mabatire akung'anima, koma zolemba zina zosinthidwa ndi zowonjezera.
7.1.2 Ndondomeko yachiwiri
Njira yolipirirayi imagwira ntchito ku 7.3.1,7.3.4,7.3.5, ndi 7.3.9.
Pambuyo pa kukhazikika kwa 1 h-ndi 4 h, motero, pa kutentha kozungulira kwa kutentha kwapamwamba kwambiri ndi kutentha kotsika kwambiri, motero, monga momwe tafotokozera mu Table 2, maselo amaperekedwa pogwiritsa ntchito malire apamwamba opangira voteji komanso pakali pano. , mpaka kuyitanitsa komweko kuchepetsedwa kukhala 0,05 It A, pogwiritsa ntchito njira yosinthira nthawi zonse mpaka njira yopangira ma voltage.

ZINDIKIRANI Magetsi ndi magetsi amatha kusiyanasiyana malingana ndi kutentha (monga kukhala pakati pa T2 ndi T3 kapena pakati pa T1 ndi T4 ya Chithunzi A.1). Nthawi yokhazikika mkati mwa nthawi yotchulidwa iyenera kulola kuti kutentha kufikidwe ngati kuli kotheka.
