Ki te tohatoha koe ki roto i ngā hanganga waea, ko tetokotoko whenua pourewa waeaHe māmā noa iho te āhua o te rārangi i runga i tō ota hoko, ā, kāore e rite ki te āhua o mua. Ko te tokotoko te wāhanga iti rawa te utu i roto i te pūnaha whenua, engari koia te mea e whakatau ana mēnā ka ora te teihana turanga i tōna wā uira tuatahi — me te mēnā ka hoko anō tō kiritaki i a koe.Ka hangaia e mātou he tokotoko whenua here parahi me te paparanga parahi parakore 0.254 mm e herea ana ki te matua maitai kukū-teitei, ā, i muri i te 12 tau i te tēpu kaweake, ka taea e au te kī atu ko ngā kaituku e angitu ana ko te hunga e hoko ana i te tokotoko hei whakaritenga, ehara i te mea he taonga hokohoko.Mā tēnei aratohu koe e whakamārama ngā whakatakotoranga e tika ana, ngā paerewa ka whakahuatia e ō kiritaki, ngā whakamātautau e whakaatu ana i tētahi tokotoko rūpahu i roto i te meneti kotahi, me ngā taipitopito tono e wehewehe ana i tētahi ipu maeneene mai i tētahi kereme.
- Me mau he paparanga parahi o te 0.254 mm (254 microns) i runga i te matua maitai o te tokotoko whenua o te pourewa waea, nā te mea ka waikura ngā mea angiangi katoa mō ngā tau maha i mua i te mutunga o te roa o te hoahoa o te pourewa.
- E whakamahia ana e mātou te IEC 62561-2 hei paerewa wāhanga e tautuhi ana i ngā whakaritenga whakamātautau mō ngā irahiko whenua, ā, e whakatakoto ana te pukapuka ā-papa R56 a Motorola i te whāinga hoahoa whenua 5-ohm rongonui e riro mai ana i te nuinga o ngā whakatakotoranga pourewa.
- Ko te kaha kume o ā mātou tokotoko parahi herea ka tukuna ki te 580 N/mm², neke atu rānei, kia ora ai i te whiunga hama ki te oneone mārō i te wā e piko ai ngā tokotoko parahi totoka, e ngatata ai ngā tokotoko piauau.
- Ka whakawhirinaki mātou ki tētahi tirotiro mara kotahi meneti te roa — te caliper i runga i te paparanga, te aukume i runga i te uho, te whakamātautau piko i runga i te tauira — ka hurahia te nuinga o ngā tokotoko kounga iti i mua i te taenga ki te pourewa.
- E whakaputa ana tā mātou wheketere i te 50,000 ngā rākau parahi herea ia marama, e 10 ngā wahi i te paihere me te 20 ki te 50 ngā paihere mō ia papa, ka tukuna mai i Shanghai, i Ningbo rānei me te huinga tuhinga kaweake katoa.
Ehara te pourewa i te whare: he aha i pā ai ngā ture uaua ki te whakatinanatanga o ngā hononga waea?
Kua kite ahau i te nuinga o ngā kaituku mahi tahi e ako ana i tēnei akoranga. He hanganga teitei, e kitea ana, he maha ngā wā kei runga i te pukepuke te pourewa waea, he mea whakapiripiri ngā hiko tairongo ki tōna turanga - koinei te huinga kino rawa atu mō te uira.E toru ngā mahi a te pūnaha whenua i te papa o te pourewa i te wā kotahi: te whakakore i ngā pānga tika mai i te taunga rererangi, i te hanganga rānei, te kawe i te iahiko hapa mai i te pūtake hiko, me te hoatu i tētahi tohutoro ma ki te taputapu reo irirangi hei pupuri i te haruru kia kore e uru ki te ara tohu.Ki te ngaro tētahi o ngā mea e toru, ka kitea e te kaiwhakahaere i roto i ngā tatauranga rahunga i roto i te tau kotahi.
E ai ki ā mātou wheako, ko te hoahoa o te papaanga he rite tonu te angaanga: he ara iahiko mowhiti tanumia huri noa i te turanga me te piringa o te pourewa, he tokotoko poutū e werohia ana i ngā wā i waenganui i taua mowhiti, he hononga ki ia waewae o te pourewa, me tētahi pūwāhi ōrite kotahi e tūtaki ai te hiko, te waea me te whenua tiaki uira.Ko te tokotoko oneone here parahi te huānga poutū i roto i te nuinga o ēnei hoahoa, nā te mea koinei anake te huarahi whai hua ki te toro atu ki te oneone makuku, iti te ātete e rua ki te toru mita te hohonu.E kite ana tātou i te tauira kotahi i roto i ngā whakaritenga mai i ngā kaikawe i te Tonga-mā-rāwhiti o Āhia, ngā towercos i Āwherika me ngā whatunga haumaru-tūmatanui i Amerika Latina: mowhiti me ngā tokotoko, tokotoko me te mowhiti, kāore he okotahi.
Ngā paerewa kei muri i te tokotoko: ko ēhea tuhinga ka tukuna atu e tō kiritaki ki a koe?
Ka kitea e mātou, ina arotakehia e te miihini o te towerco tō tuku, kāore rātou e tautohetohe tuatahi mō te utu — engari ka tautohetohe rātou mō ngā paerewa. E whā ngā tuhinga e piri ana ki runga ake i taku tēpu nā te mea he maha tonu ngā wā ka puta ake.IEC 62561-2ko te paerewa taumata-wāhanga e tohu ana i ngā whakaritenga me ngā whakamātautau mō ngā irahiko whenua whakarewa, nō reira me whakaatu e te tokotoko e kī ana he tutuki ana ngā whakaritenga he taunakitanga whakamātautau e whakahē ana.Mō te hoahoa taumata-pae, ko tePukapuka ā-ringa mō Motorola Solutions R56koia tonu te tohutoro e riro mai ana i ngā kaihanga o te papa reo irirangi puta noa i te ao, me tana whāinga hoahoa whenua 5-ohm me tana āhua mowhiti-me-tokotoko. I roto i te whare tiaki,ETSI EN 300 253e tautuhi ana i te whirihoranga whenua me te hononga mō ngā pokapū whakawhitiwhiti kōrero, me te paparanga tiaki-uiraNFPA 780e whakahaere ana i ngā mākete e whai ana i ngā mahi a te US.
| Paerewa | Ngā mea e whakahaeretia ana e ia | Te tikanga mō tō ota tokotoko |
|---|---|---|
| IEC 62561-2 | Ngā whakamātautau wāhanga mō ngā kaiārahi me ngā irahiko whenua | Pātai atu ki te wheketere mō ngā taunakitanga whakamātautau mō te hikohiko tonu. |
| Motorola R56 | Te hoahoa me te tirotiro i te whenua o te pae whakawhitiwhiti kōrero | Me tumanako ki tētahi whakatakotoranga whāinga pae 5-ohm me te mowhiti-me-tokotoko. |

E hiahia ana mātou ki te tohu i te hua o te hoko e ngaro ana i te nuinga o ngā kaituku.Ko te wheketere e hanga pono ana i runga i ēnei anga ka pupuri i ngā pūrongo whakamātautau, ngā tiwhikete rauemi me ngā tuhinga rahinga mō ia rota whakaputa, ko te kaihokohoko ia e whakaari ana he wheketere ka taea anake te tuku i tētahi "tiwhikete kounga" whānui, kāore he tau rota, kāore hoki he taiwhanga kei muri.Kei te whakahaere mātou i tētahi pūnaha kounga ISO 9001:2008 — ka taea e koe te tirotiro he aha ngā mea e hiahiatia ana e taua paerewa i runga i tewhārangi mana o te ISO 9001— ā, mō ngā kaihoko e hiahia ana ki te whakamātautau hiko a te hunga tuatoru o ngā rauemi whenua e whakamahia ana mō ngā kaupapa e tata ana ki ngā ratonga,CEPRI (Te Whare Rangahau Hiko Hiko o Haina)ko te mana whakahaere e whakaaetia ana e ngā poari tuku tono.
Parahi piri, parahi piauau, parahi totoka rānei: he aha te whakataurite o ngā irahiko e toru?
Ka rongo mātou i ō kaihoko e pātai ana he aha e kore ai rātou e hoko noa i te tokotoko piauau iti rawa te utu, te mea parahi totoka "pai rawa atu" rānei. E toru ngā rārangi e whakautua ana e au i ia wā. I roto i ā mātou tuku me ngā pūrongo i te mara ka tae mai ki a mātou, ka ngaro te kiri konutea o te maitai piauau i roto i ngā tau i roto i te oneone kaha, ā, ina pakaru te konutea, ka tere te waikura o te matua maitai. He tino pai te mahi a te parahi totoka engari ka piko i te wā e taraiwa hohonu ana, ā, he maha ngā wā ka nui ake te utu mō ia mita.Ko te tokotoko parahi e herea ana e te mea hangarau he mea tino pai: ka homai e te matua maitai te kaha kume 580 N/mm² mō te taraiwa, ā, ko te kiri parahi 0.254 mm ka homai te whanonga waikura e tata ana ki te parahi totoka kia neke atu i te 50 tau te roa o te ora ratonga kua whakatauria.
| Taonga | He parahi kua herea (tō mātou awhe) | Rino whakakoi | Parahi totoka |
|---|---|---|---|
| Te roa o te waikura i roto i te oneone noa | ≥50 tau | I raro iho i te 15 tau te roa o te ora i roto i te oneone pukuriri | ≥50 tau |
| Te kaha o te taraiwa | ≥580 N/mm² | Teitei, engari e kapi ana i ngā kapiti i te wā e taraiwa ana | Iti — piko i te oneone mārō |
| Whāngai paparanga i te taraiwa | Ka ora tonu te here ngota i te wā e whiua ana | Ngā maramara konutea kua tangohia | Kāore he paparanga e ngaro |
| Te utu whaitake mō ngā rauemi | Tūāpapa | He iti ake te utu ā-mua, he nui ake te utu mō te wā roa | He maha ngā wā turanga |
| Te āhua o te tahae para | Iti — te matua maitai i roto | Kāore | Teitei |
Mō te utu, ka noho pūmau taku aro ki te kounga o ngā tuhinga, engari ka taea e au te whakapuaki i tētahi ōwehenga pono mai i ā mātou whakahuatanga kaweake hei āwhina i te take pakihi:Ko te utu o te tokotoko parahi herea he 30% ki te 50% te iti iho i te diameter me te roa ōrite o te parahi totoka, nā te mea ko te matua maitai te mea nui hei whakakapi i te nuinga o te papatipu parahi.Ki te whakatauritea ki te konukōre, he nui ake te utu i te tīmatanga, he iti ake hoki i te roanga o te oranga o te pourewa — ā, ko ngā kaiwhakahaere pourewa, he rerekē ki ngā kaihoko whare, ka tatau i te utu mō tōna oranga katoa.
Ehara te 0.254 mm i te pepeha: me pēhea te manatoko i te tokotoko i mua i te whakatōnga ki te whenua?
Ki tā mātou whakaaro, ko te matotoru o te paparanga parahi te mea tino kino rawa atu i tēnei mahi. E 0.254 mm (254 maikorona) neke atu rānei te parahi parakore o ā mātou tokotoko, ā, ko tāku kupu anō tēnei ki ngā kaihokohoko katoa: me ine e koe i te tukunga tuatahi.E toru ngā tirotirohanga mara e whakaatu ana i ngā tokotoko iti iho i te paerewa i roto i te iti iho i te meneti — he caliper, he maikiromita rānei me te ine matotoru paparanga i runga i te tauira kua tapahia, he whakamātautau aukume e whakaū ana i te matua maitai, me te whakamātautau piko, te whakamātautau hama rānei i runga i te tokotoko patunga tapu kotahi.Ka ora tonu te tokotoko piri ina tukia ki te kirikiri, ā, kāore e pakaru te kiri; ka kitea tonutia ngā whiu hiriwa maitai i te tokotoko angiangi kua whakakikoruatia.
Kua ako mātou he mea nui ake te tika i tā te hunga tauhou e whakaaro nei. Ka mau te hapa tika i roto i te 1 mm ia mita i roto i tā mātou rārangi, ā, ko te take he ahupūngao māmā noa iho:ka hikoi taha te tokotoko piko i raro i te hama, kāore e tae ki te hohonutanga hoahoa, ā, ka mahue te mowhiti me te iti iho o ngā mita poutū o te hikohiko i tā te kaihangarau i tatau ai.Nā te mea e whakawhirinaki ana te ātete whenua ki te roa o te hiko kua tanumia, ka huri puku te tokotoko piko i te hoahoa 5-ohm ki te mooni 9-ohm, ā, kāore tetahi e kite i tēnei tae noa ki te whakamātautau tuatahi i rahua.
Ngā miro, ngā pito me ngā roa: me pēhea te whakataurite i te tokotoko ki te hoahoa o te pourewa?
I roto i ngā pire rahinga o te pourewa e kitea ana e mātou, ko te nuinga o ngā whakatakotoranga e kī ana he tokotoko 5/8 inihi (14.2 mm) 3/4 inihi rānei te roa, 2.4 m, 3.0 m rānei, ā, ko te whānuitanga o ā mātou mahi whakaputa he whānui mai i te 14.2 mm ki te 25 mm me te roa mai i te 1.2 m ki te 3.0 m me ngā pito miro, papatahi, koi rānei. Ki tā mātou whakaaro ko te kōwhiringa tino nui i te papaanga ko te whirihoranga pito.Ka pana tika ngā tokotoko koi; ka taea e ngā tokotoko miro te hono, kia taea ai e te tira te mekameka i ngā tokotoko e rua, e toru rānei kia eke ki te rima, ki te ono mita rānei ina ngoikore te ātete o te oneone pāpaku.Ka whakamahia e mātou ngā miro kua pōkaihia hei mīhini, kaua hei tapahi i ngā miro, nā te mea ka noho tonu te paparanga parahi i te pūtake miro i te wāhi e whakaatuhia ai te maitai i roto i ngā miro kua tapahia.
Kotahi te taipitopito whakatakotoranga e tohea ana e au kia tuhia: me ōrite te taputapu hononga ki te tokotoko.Me whakahuahia ngā utu mō ngā rawhi, ngā hononga me ngā pane taraiwa i roto i te kaipuke kotahi me ngā tokotoko, nā te mea ko ngā paerewa miro kāore i te ōrite te amuamu tāutanga matua e rongohia ana e mātou mai i ngā kaihokohoko i tiki motuhake i te tokotoko me te taputapu.Mō te arataki mowhiti whakapae, he maha ngā pou e hono ana i ngā tokotoko ki ā mātouwaea maitai kua whakakikoruatia ki te parahi, e pupuri ana i te pūnaha tanumia katoa i runga i te whakaaro kotahi o te parahi-ki-runga-maitai. Ka taea e koe te kite i te whānau hiko katoa i roto i tā mātoukāwai tokotoko whenua whakakikoruatia ki te parahi, tae atu ki tetokotoko whenua parahihe momo rerekē mō ngā kaupapa e tohu ana i taua ingoa.
