Ngā Pūrongo Hua
He aha ngā mea ka tūpono ina kapea e koe ngā Paerewa Whakatutukitanga mō ngā Taura Taputapu?
Ka ngaro te tohu, ka rahua ngā taputapu, me ngā tūponotanga haumaru hoki mēnā kāore e tutuki ngā whakaritenga o ngā taura taputapu.
E whakaatu ana ngā raraunga ahumahi e 80% o ngā whakaurunga kāore i te tutuki i ngā whakaritenga ka pāngia e ngā raruraru i roto i ngā marama 18.
Akohia ngā hua tūturu o te kore e whai i ngā whakaritenga EN 50288-7, IEC 60332, NEC rānei – me te take e tiakina ai tō tipu e te tutuki i ngā whakaritenga.
Me pēhea te whiriwhiri i te taura taputapu maha-takirua tika mō tō kaupapa?
Ko te whiriwhiri i ngā taura taputapu maha-takirua me whakatau i te maha o ngā takirua (1-100+), te rahi o te ara iahiko (18-24 AWG / 0.5-2.5mm²), te momo ārai (pepa konumohe/whiri/whakakotahi), me te rauemi koti (PVC/LSZH/PUR).
Kei roto i tēnei aratohu te hanganga ture o te EN 50288-7 me tētahi anga kōwhiringa taahiraa-i-te-taahiraa mō ngā tohu anaro me ngā tohu mamati.
He Whakamārama mō te Paerewa EN 50288-7: Ngā Mea Me Mōhio Ngā Kaihoko Taura Taputapu
Ko te EN 50288-7 te paerewa Pākehā mō ngā taura taputapu me te whakahaere, e whakaatu ana i ngā tawhā hiko (ātete, kaha, whakaiti), ngā āhuatanga hangarau, te ātete mura, me ngā whakatauranga pāmahana.
Me manatoko e ngā kaihoko te tutuki i ngā whakaritenga mō te tohu CE me ngā whakaritenga kaupapa.
Akohia ngā whakaritenga matua me te rārangi arowhai kōwhiringa.
Twisted Pair vs Coaxial vs BS5308: Ko tēhea taura taputapu me whiriwhiri e koe?
Ko te whiriwhiri i waenga i te takirua miro (whakaiti whakawhiti kōrero), te coaxial (auau-tiketike), me te BS5308 (whakatakotoranga hinu me te hau) ka whakawhirinaki ki te momo tohu, te tawhiti, me te taiao.
He pai te hononga miro mō te 4-20mA me te RS485. He pai te hononga honohono mō te auau-tiketike me te ataata.
Ka tāpirihia e te BS5308 te parenga ā-mīhini me te whakatauranga IS mō ngā tipu hinu matū.
He aha te Taura Taputapu Ārai, ā, he aha te Hiranga o te Ārai?
Me kikorangi mārama ngā taura haumaru ā-roto (RAL 5015) e ai ki te IEC 60079-14 hei tautuhi i ngā wāhi morearea.
Mā tēnei waehere tae ā-ture ka taea e ngā kaimahi hiko te wehewehe tonu i ngā taura hiko IS mai i ngā taura hiko ehara i te IS, ā, ka ārai i te hononga tūpono o te hiko morearea.
Me kikorangi te taura haumaru ā-roto?
Ae, e ai ki te IEC 60079-14, ME whai kikorangi mārama (RAL 5015) te anga o waho o ngā taura haumaru hei tautuhi i ngā wāhi morearea.
Mā tēnei waehere tae ā-ture ka taea te kite wawe i ngā ara iahiko IS, ā, ka ārai i te hononga tūpono o te hiko ehara i te IS.
He iti noa ngā tūponotanga mō ngā taura tino iti me ngā whakaurunga o nāianei.
He aha te Taura Ārai Haumaru ā-roto SWA?
He taura SWA (Steel Wire Armour) haumaru ā-roto e whakakotahi ana i te herenga pūngao (IS) me te tiaki ā-ringa (whakamarumaru waea maitai). Ātete kuru tae atu ki te 4,000 N/10cm, tiaki ki ngā kiore/para, me te kaha kume teitei mō ngā whakaurunga wāhi morearea uaua. Ka mau tonu te hanganga LSZH kikorangi mārama i te tutuki o te IS, ā, ka roa ake te mau o te whakamarumaru.
He aha te taura whakaoho ahi haumaru ā-roto?
Ka whakakotahi te taura whakaoho ahi haumaru-ā-roto i te herenga pūngao (ka ārai i te mura) me te pono o te ara iahiko (ka pupuri i te mahi i te wā e mura ana).
Kua whai tiwhikete mō ngā wāhi morearea (Rohe 0/1/2) me ngā whakatauranga pēnei i te FE180 (ora ahi 180 meneti) me te hipoki LSZH.
Akohia me pēhea e kitea ai e ngā taura ahi a IS ngā ahi, me te kore e puta ai.
He aha i kikorangi ai ngā taura haumaru ā-roto?
Ko ngā taura haumaru ā-roto he kikorangi (RAL 5015) e ai ki te IEC 60079-14 hei tautuhi tere i ngā wāhi morearea. Mā tēnei waehere tae whakahau ka taea e ngā kaihikohiko te wehewehe tonu i ngā ara iahiko IS mai i ngā taura hiko kore-IS—ka ārai i te hononga tūpono o te hiko morearea. Akohia te paerewa, ngā okotahi, me ngā paearu whiriwhiri.
