Kodi Chimachitika N'chiyani Mukasiya Kutsatira Miyezo Yogwiritsira Ntchito Zingwe Zopangira Zida?
Zingwe zolumikizira zida zosatsatira malamulo zimayambitsa kutayika kwa chizindikiro, kulephera kwa zida, komanso ngozi zachitetezo.
Deta ya makampani ikuwonetsa kuti 80% ya makina osatsatira malamulo amakumana ndi mavuto mkati mwa miyezi 18.
Dziwani zotsatira zenizeni za kuswa malamulo a EN 50288-7, IEC 60332, kapena NEC - komanso chifukwa chake kutsatira malamulo kumateteza chomera chanu.
Kodi Mungasankhe Bwanji Chingwe Choyenera cha Zida Zambiri Pa Ntchito Yanu?
Kusankha zingwe zolumikizira zida zamitundu yambiri kumafuna kudziwa kuchuluka kwa zingwe (1-100+), kukula kwa kondakitala (18-24 AWG / 0.5-2.5mm²), mtundu wa zotchingira (foil/luid/composite), ndi zinthu za jekete (PVC/LSZH/PUR).
Bukuli likufotokoza za kutsatira malamulo a EN 50288-7 komanso njira yosankhira masiginecha a analogi ndi digito yomwe imachitika pang'onopang'ono.
Kufotokozedwa kwa EN 50288-7 Standard: Zimene Ogula Zingwe Zogwiritsira Ntchito Zipangizo Ayenera Kudziwa
EN 50288-7 ndiye muyezo wa ku Europe wa zida ndi zingwe zowongolera, zomwe zimafotokozera magawo amagetsi (kuletsa, mphamvu, kuchepetsa), mawonekedwe a makina, kuchedwa kwa moto, ndi kuchuluka kwa kutentha.
Ogula ayenera kutsimikizira kuti akutsatira malamulo a CE ndi zofunikira za polojekitiyi.
Dziwani zofunikira zazikulu ndi mndandanda wazinthu zomwe mungasankhe.
Twisted Pair vs Coaxial vs BS5308: Ndi Chingwe Chiti Chogwiritsira Ntchito Chomwe Muyenera Kusankha?
Kusankha pakati pa twisted pair (crosstalk reduction), coaxial (high-frequency), ndi BS5308 (mafuta ndi gasi spec) kumadalira mtundu wa chizindikiro chanu, mtunda, ndi malo omwe muli.
Ma twisted pair ndi abwino kwambiri pa 4-20mA ndi RS485. Coaxial ya ma frequency apamwamba komanso makanema.
BS5308 imawonjezera chitetezo cha makina ndi IS rating pa zomera za petrochemical.
Kodi Chingwe Chotetezedwa ndi Chiyani Ndipo N’chifukwa Chiyani Kuteteza N’kofunika?
Zingwe zotetezeka mkati mwake ziyenera kukhala zopepuka ngati buluu (RAL 5015) malinga ndi IEC 60079-14 kuti zizindikire malo oopsa.
Khodi yofunikira iyi ya utoto imalola akatswiri amagetsi kusiyanitsa nthawi yomweyo ma circuits a IS ndi zingwe zamagetsi zomwe si za IS, kupewa kulumikizana mwangozi kwa mphamvu zoopsa.
Kodi ma volts 24 ndi otetezeka mkati mwake?
Yankho Lolunjika ndi: Ayi.
Kodi Chingwe Chotetezeka Chamkati Chiyenera Kukhala Chabuluu?
Inde, malinga ndi IEC 60079-14, zingwe zotetezeka mwachibadwa ZIYENERA kukhala ndi chivundikiro chakunja cha buluu (RAL 5015) kuti zizindikire malo oopsa.
Khodi yamtundu yofunikira iyi imalola kuzindikira mwachangu ma circuits a IS, kuletsa kulumikizana mwangozi kwa mphamvu yosakhala ya IS.
Pali zochepa zomwe zingagwiritsidwe ntchito pa zingwe zazing'ono kwambiri komanso zomwe zilipo kale.
Kodi Chingwe Chotetezedwa Mwachilengedwe cha SWA Armoured ndi Chiyani?
Chingwe chotetezeka cha SWA (Steel Wire Armour) chimaphatikiza mphamvu zoletsa (IS) ndi chitetezo cha makina (chitsulo choteteza waya). Kukana kuphwanya mpaka 4,000 N/10cm, chitetezo cha makoswe/zilombo zolusa, komanso mphamvu yayikulu yolimba kuti zigwiritsidwe ntchito moopsa. Chigoba cha LSZH chabuluu chopepuka chimasunga kutsata kwa IS pomwe chitetezo chimawonjezera kulimba.
Kodi Chingwe Choteteza Moto Choteteza Mwachilengedwe ndi Chiyani?
Chingwe choteteza moto chomwe chili ndi chitetezo chamthupi chimaphatikiza kuchepetsa mphamvu (kuletsa kuyaka) ndi umphumphu wa dera (kumasunga ntchito yake panthawi ya moto).
Yovomerezeka m'malo oopsa (Zone 0/1/2) yokhala ndi ma ratings monga FE180 (kupulumuka kwa moto kwa mphindi 180) ndi LSZH sheathing.
Dziwani momwe zingwe zozimitsira moto za IS zimadziwira moto popanda kuuyambitsa.
Nchifukwa chiyani zingwe zotetezeka mkati mwathu ndi zabuluu?
Zingwe zotetezeka mkati mwake zimakhala zabuluu (RAL 5015) malinga ndi IEC 60079-14 kuti zidziwike mwachangu m'malo oopsa. Khodi yofunikira iyi yamitundu imalola akatswiri amagetsi kusiyanitsa nthawi yomweyo ma circuits a IS ndi zingwe zamagetsi zomwe si za IS—kuletsa kulumikizana mwangozi kwa mphamvu zoopsa. Phunzirani muyezo, zosiyana, ndi njira zosankhira.
