Kufotokozedwa kwa EN 50288-7 Standard: Zimene Ogula Zingwe Zogwiritsira Ntchito Zipangizo Ayenera Kudziwa
- Yankho Lolunjika: EN 50288-7 Imafotokoza Magwiridwe Antchito, Osati Kapangidwe Kokha
Anthu nthawi zonse amafunsa kuti:"Kodi zofunikira pa chingwe cholumikizira zida ndi ziti?"
Yankho losavuta:Muyezo wa EN 50288-7 ndi muyezo wa ku Europe womwe umalongosola zazofunikira zamagetsi, makina, kuchedwa kwa moto, ndi kutenthaza zida ndi zingwe zowongolera zomwe zimagwiritsidwa ntchito mumakina owongolera njira zamafakitale.
| Zomwe EN 50288-7 Ikuphimba | Zimene Sizikuphimba |
| Magawo amagetsi (impedance, capacitance, attenuation, resistance) | Zipangizo zotetezera kutentha (zimawonetsa magwiridwe antchito, osati maphikidwe) |
| Kugwira ntchito bwino poteteza (zofunikira pakuwunika) | Njira zoyikira (onani EN 60079-14 kuti mudziwe madera oopsa) |
| Kapangidwe ka makina (kupindika kwa radius, kukoka, kukhudza) | Kuwerengera njira zoyendetsera chingwe kapena kudzaza thireyi |

| Kutsatira chizindikiro cha CE (muyezo wogwirizana) | Satifiketi ya malo oopsa (Ex) (onani IEC 60079-11/14) |
Chifukwa Chake EN 50288-7 Ndi Yofunika kwa Ogula:
- Chizindikiro cha CE– EN 50288-7 ndi muyezo wogwirizana pansi pa Low Voltage Directive (LVD) pamsika waku Europe.
- Zofunikira pa polojekitiMakampani ambiri opanga mainjiniya (EPCs) amafuna kuti mafakitale a mafakitale azitsatira malamulo a EN 50288-7 (oyeretsera, mankhwala, magetsi, ndi mankhwala).
- Chitsimikizo cha magwiridwe antchito– Mosiyana ndi “chingwe chogwiritsira ntchito zida” cha generic, EN 50288-7 imapereka magawo amagetsi oyezedwa omwe mungatsimikizire.
Pa Dingzun Cable,Zingwe zathu zonse zolumikizira zida zimapangidwa motsatira zofunikira za EN 50288-7 - ndi malipoti oyeserera olembedwa okhudza kuletsa, mphamvu, kuchepa kwa mphamvu, komanso kuchedwa kwa moto. Tikukuthandizani pazosowa zanu zolembera chizindikiro cha CE komanso kutsatira malamulo a polojekiti.
- Magawo Amagetsi Apakati: Impedance, Capacitance, Attenuation
EN 50288-7 imatchula magawo atatu ofunikira amagetsi omwe amakhudza mwachindunji kukhulupirika kwa chizindikiro.
Tebulo 1: EN 50288-7 – Mafotokozedwe Ofunikira a Zamagetsi
