Mpanda wamagetsi umabwera mosiyanasiyana makulidwe, mawonekedwe, zida, ndi mapangidwe.Ngakhale kuti onse ali ndi zolinga zofanana - kuteteza zipangizo zamagetsi zotsekedwa kuchokera ku chilengedwe, kuteteza ogwiritsa ntchito kugwedezeka kwa magetsi, ndi kukwera zipangizo zamagetsi - zikhoza kukhala zosiyana kwambiri.Chotsatira chake, zofunikira pazitsulo zamagetsi zimakhudzidwa kwambiri ndi zosowa za ogwiritsa ntchito.
Tikamalankhula za zofunikira zamakampani pamipanda yamagetsi, nthawi zambiri timalankhula za miyezo osati malamulo ovomerezeka (ie, zofunika).Miyezo iyi imathandizira kulumikizana pakati pa opanga ndi ogula.Amalimbikitsanso chitetezo, kapangidwe kake bwino, komanso magwiridwe antchito apamwamba.Lero, tikambirananso zina mwazomwe zafala kwambiri zotsekera mpanda, komanso nkhawa zomwe anthu amakhala nazo akamayitanitsa kabati yamagetsi kapena mpanda.
Miyezo Yodziwika Pamipanda
Ambiri opanga zipinda zamagetsi amatsatira zofunikira zachitetezo zomwe zimakhazikitsidwa ndi gulu lodziwika bwino la mindandanda.Ku United States, Underwriters Laboratories (UL), National Electrical Manufacturers Association (NEMA), ndi EUROLAB ndi mabungwe atatu akulu amndandanda.Opanga ambiri amagwiritsa ntchito International Electrotechnical Commission on a global scale (IEC), yomwe imakhazikitsa banja la miyezo yotsekera magetsi, ndi Institute of Electrical and Electronics Engineers (IEEE), bungwe laukadaulo lomwe limakhazikitsa miyezo yopititsa patsogolo ukadaulo ndikupindulitsa anthu. .
Miyezo itatu yodziwika bwino yamagetsi imasindikizidwa ndi IEC, NEMA, ndi UL, monga tanenera kale.Muyenera kuwona zolemba za NEMA 250, IEC 60529, ndi UL 50 ndi 50E.
IEC 60529
Miyezo yachitetezo cha ingress imadziwika pogwiritsa ntchito manambalawa (omwe amadziwikanso kuti Characteristic Numerals) (omwe amadziwikanso kuti ma IP ratings).Amalongosola mmene mpandawo umatetezera bwino zomwe zili m’kati mwake ku chinyezi, fumbi, zinyalala, anthu, ndi zinthu zina.Ngakhale muyezo umalola kudziyesa nokha, opanga angapo amakonda kuti zinthu zawo ziziyesedwa pawokha kuti zikugwirizana.
NEMA 250
NEMA imapereka chitetezo cha ingress monga momwe IEC imachitira.Imaphatikizanso zomangamanga (zocheperako zopanga), magwiridwe antchito, kuyesa, dzimbiri, ndi mitu ina.NEMA imayika mpanda malinga ndi Mtundu wawo osati ma IP awo.Zimathandizanso kudzidalira, zomwe zimathetsa kufunika koyendera fakitale.
UL 50 ndi 50E
Miyezo ya UL imatengera zomwe NEMA imafunikira, koma imafunikiranso kuyezetsa kwa gulu lachitatu ndikuwunika patsamba kuti zitsimikizire kuti zikutsatira.Miyezo ya kampani ya NEMA imatha kutsimikiziridwa ndi satifiketi ya UL.
Chitetezo cha ingress chimayankhulidwa mumiyezo yonse itatu.Amawunika kuthekera kwa mpanda wachitetezo polowera zinthu zolimba (monga fumbi) ndi zakumwa (monga madzi).Amaganiziranso chitetezo cha anthu kuzinthu zowopsa za mpanda.
Mphamvu, kusindikiza, zakuthupi/kumaliza, kutsekereza, kuyaka, mpweya wabwino, kukwera, ndi chitetezo cha kutentha zonse zimaphimbidwa ndi UL ndi NEMA yomanga mpanda.Kulumikizana ndi kukhazikitsa kumayankhidwanso ndi UL.
Kufunika kwa Miyezo
Opanga ndi ogula amatha kulankhulana mosavuta za mtundu wa chinthu, mawonekedwe ake, komanso kuchuluka kwa kulimba kwake chifukwa cha miyezo.Amalimbikitsa chitetezo ndikulimbikitsa opanga kupanga zinthu zomwe zimagwira ntchito bwino komanso zimakwaniritsa miyezo yeniyeni yogwirira ntchito.Chofunika kwambiri, amathandiza ogwiritsa ntchito kusankha mwanzeru kuti athe kusankha malo otchinga omwe amagwirizana ndi zomwe akufuna.
Pakadakhala kusiyana kwakukulu pamapangidwe azinthu ndi magwiridwe antchito pakadapanda miyezo yokhazikika.M'malo mongoyang'ana zopeza mtengo wotsika kwambiri, timalimbikitsa ogula onse kuti aganizire miyezo yamakampani akamagula zipinda zatsopano.Ubwino ndi magwiridwe antchito ndizofunikira kwambiri kuposa mtengo wanthawi yayitali.
Zofuna Makasitomala
Chifukwa opanga mpanda wamagetsi amangofunika kukwaniritsa zofunikira zochepa (miyezo yawo), zofunikira zambiri zotsekera magetsi zimachokera kwa ogula.Kodi makasitomala amafuna chiyani m'malo otchingidwa ndi magetsi?Kodi maganizo awo ndi zotani?Mukamayang'ana kabati yatsopano yoti mugwiritse ntchito zamagetsi, ndi zinthu ziti zomwe muyenera kuyang'ana?
Ganizirani izi popanga mndandanda wazofunikira ndi zomwe mukufuna ngati mukufuna malo otchinga magetsi:
Zinthu zotchinga
Mipanda imapangidwa ndi zinthu zingapo, kuphatikiza zitsulo, pulasitiki, fiberglass, die-cast, ndi zina.Ganizirani za kulemera, kukhazikika, mtengo, zosankha zokwera, maonekedwe, ndi kulimba kwa zosankha zanu pamene mukuzifufuza.
Chitetezo
Musanagule, yang'anani mavoti a NEMA, omwe akuwonetsa kuchuluka kwa chitetezo cha chilengedwe.Chifukwa mavotiwa nthawi zina samamveka bwino, lankhulani ndi wopanga / wogulitsa za zosowa zanu pasadakhale.Mavoti a NEMA atha kukuthandizani kudziwa ngati mpanda ndi woyenera kugwiritsidwa ntchito m'nyumba ndi kunja.kaya ingateteze ku ingress ya madzi, kaya ikhoza kupirira mapangidwe a ayezi, ndi zina zambiri.
Kukwera ndi Kuwongolera
Kukwera ndi Kuyang'ana: Kodi mpanda wanu udzakhala womangidwa pakhoma kapena wopanda kuima?Kodi mpandawu ukhala molunjika kapena mopingasa?Onetsetsani kuti mpanda womwe mwasankha ukukwaniritsa zofunikira izi.
Kukula
Kusankha kukula koyenera kungawoneke molunjika, koma pali zotheka zambiri.Ngati simusamala, mutha "kugula mochulukira," kugula zotsekera zambiri kuposa momwe mukufunira.Komabe, ngati mpanda wanu udzakhala waung'ono kwambiri mtsogolomu, mungafunike kuwongolera.Izi ndizowona makamaka ngati mpanda wanu udzafunika kutengera kupita patsogolo kwaukadaulo.
Kuwongolera Nyengo
Kutentha kwamkati ndi kunja kungawononge zida zamagetsi, choncho kuwongolera nyengo ndikofunikira.Mungafunike kufufuza njira zotumizira kutentha kutengera kutentha kwa zida zanu ndi malo ake akunja.Ndikofunikira kusankha njira yozizirira yolondola ya mpanda wanu.
Mapeto
Onani Eabel Manufacturing ngati mukuyang'ana kampani yomwe ingakupangireni zitsulo zabwino kwambiri.Mipanda yathu yaukadaulo, yapamwamba kwambiri imathandizira makampani opanga ma telecom kuti atukule ndikuwongolera zomwe amapereka pamanetiweki.
Timapereka mtundu wa NEMA 1, mtundu wa 2, mtundu wa 3, mtundu wa 3-R, mtundu wa 3-X, mtundu wa 4, ndi zitsulo zamtundu wa 4-X, zomwe zimapangidwa ndi aluminiyamu, zitsulo zotayidwa, zitsulo za carbon, ndi zitsulo zosapanga dzimbiri.Lumikizanani nafe, kuti mudziwe zambiri, kapena funsani mtengo waulere pa intaneti.
