He huarahi ngāwari ngā whakaahua wera ki te tautuhi i ngā rerekētanga pāmahana e kitea ana i roto i ngā ara iahiko hiko toru-wāhanga ahumahi, ki te whakataurite ki ō rātou āhuatanga mahi noa. Mā te tirotiro i ngā rerekētanga wera o ngā wāhanga e toru, ka taea e ngā tohunga hangarau te kite wawe i ngā hapa mahi i runga i ngā waewae takitahi nā te kore taurite, te taumaha rawa rānei.
Ko te kore taurite o te hiko ka puta mai i ngā kawenga rerekē o te āhua, engari ka puta pea i ngā take taputapu pēnei i ngā hononga ātete teitei. Mā te kore taurite iti o te ngaohiko e tukuna ana ki te motuka ka nui ake te kore taurite o te iahiko ka puta he wera tāpiri, ka whakaiti i te taipana me te whai huatanga. Mā te kore taurite nui ka pakaru te fuse, ka tūkino rānei te kaiwawao ka puta te huringa kotahi me ngā raruraru e pā ana ki a ia pēnei i te wera me te kino o te motuka.
I roto i te mahi, he tino uaua ki te whakataurite tika i ngā ngaohiko puta noa i ngā wāhanga e toru. Hei āwhina i ngā kaiwhakahaere taputapu ki te whakatau i ngā taumata kore taurite e whakaaetia ana, ko te National Electrical
Kua tuhia e te Rōpū Kaihanga (NEMA) ngā whakaritenga mō ngā momo taputapu rerekē. He wāhi whai hua ēnei paerewa hei whakataurite i te wā tiaki me te rapurongoā.
He aha te mea hei tirotiro?
Hopukia ngā whakaahua wera o ngā panera hiko katoa me ētahi atu pūwāhi hononga kawenga teitei pērā i ngā puku hiko, ngā momotu hiko, ngā mana whakahaere me ērā atu mea. Mēnā ka kitea e koe he pāmahana teitei ake, whai i taua ara iahiko ka tirotirohia ngā peka me ngā kawenga e pā ana.
Tirohia ngā panera me ētahi atu hononga me te kore e taupokina. Ko te mea pai, me tirotiro e koe ngā taputapu hiko ina tino mahana, ā, kei roto i ngā āhuatanga pumau me te iti rawa 40 ōrau o te kawenga noa. Pērā ai, ka taea te aromatawai tika i ngā inenga me te whakataurite ki ngā āhuatanga mahi noa.
He aha ngā mea hei rapu?
Me ōrite te taumahatanga ki ngā pāmahana ōrite. I roto i te āhuatanga taumaha kore taurite, ka āhua mahana ake te āhua o ngā wāhanga taumaha rawa atu i ētahi atu, nā te wera i puta mai i te ātete. Heoi, ka taea e te taumahatanga kore taurite, te taumaha rawa, te hononga kino, me te raruraru harmonic te hanga i tētahi tauira ōrite. Me ine i te taumahatanga hiko hei tautuhi i te raruraru.
Tērā pea he tohu kei te pakaru te wāhanga mēnā he matao ake i te noa te ara iahiko, te waewae rānei.
He tikanga pai te waihanga i tētahi ara tirotiro auau e whakauru ana i ngā hononga hiko matua katoa. Mā te whakamahi i te pūmanawa e haere tahi mai ana me te taputapu whakaahua wera, tiakina ia whakaahua ka hopukina e koe ki te rorohiko, ā, aroturukihia ō inenga i roto i te wā. Pērā ai, ka whai whakaahua tūāpapa koe hei whakataurite ki ngā whakaahua o muri mai. Mā tēnei tikanga koe e āwhina ki te whakatau mēnā he rerekē te wāhi wera, te wāhi matao rānei. Whai muri i ngā mahi whakatikatika, mā ngā whakaahua hou koe e āwhina ki te whakatau mēnā i angitu ngā whakatikatika.
He aha te tohu o te "mataara whero"?
Me whakarite kia matua ngā whakatikatika mā te haumaru tuatahi—arā, ngā āhuatanga o ngā taputapu e tūpono ana ki te haumaru—ā, muri iho ko te hiranga o ngā taputapu me te nui o te pikinga o te pāmahana. NETA (International Electrical
E kī ana ngā aratohu a te Testing Association) ko te iti o te pāmahana 1°C i runga ake i te taiao me te 1°C teitei ake i ngā taputapu rite me te uta rite, he tohu pea tēnei i tētahi ngoikoretanga e tika ana kia rangahaua.
E whakatūpato ana ngā paerewa NEMA (NEMA MG1-12.45) kia kaua e whakahaere i tētahi motuka i te kore taurite ngaohiko e neke atu i te kotahi ōrau. Inaa, e taunaki ana a NEMA kia whakaitihia te kaha o ngā motuka mēnā kei te whakahaerehia i te kore taurite teitei ake. He rerekē ngā ōrau kore taurite haumaru mō ētahi atu taputapu.
Ko te rahunga o te motuka he hua noa o te kore taurite o te ngaohiko. Ko te utu katoa e whakakotahi ana i te utu o te motuka, te mahi e hiahiatia ana hei whakawhiti i te motuka, te utu o te hua kua whakakorea nā te kore taurite o te whakaputanga, te whakahaere raina me te moni whiwhi i ngaro i te wā e mutu ana te raina.
Ngā mahi whai muri
Ina whakaatuhia e te whakaahua wera he mahana ake te kaiārahi katoa i ētahi atu wāhanga puta noa i tētahi wāhanga o te ara iahiko, tera pea he iti rawa te rahi o te kaiārahi, he taumaha rawa rānei. Tirohia te whakatauranga o te kaiārahi me te kawenga tuturu hei whakatau ko tēhea te take. Whakamahia he mita maha me te taputapu rawhi, he mita rawhi, he tātari kounga mana rānei hei tirotiro i te taurite o ia au me te kawenga i runga i ia wāhanga.
I te taha ngaohiko, tirohia te tiaki me te taputapu whakawhiti mō ngā hekenga ngaohiko. I te nuinga o te wā, me noho te ngaohiko raina i roto i te 10% o te whakatauranga ingoa. Ko te ngaohiko kūpapa ki te whenua he tohu pea mō te taumaha o te utaina o tō pūnaha, he tohu rānei pea mō te iahiko harmonic. Ko te ngaohiko kūpapa ki te whenua he nui ake i te 3% o te ngaohiko ingoa me whakaoho i ētahi atu rangahau. Whakaarohia hoki ka rerekē ngā kawenga, ā, ka taea e te āhua o te wāhanga te heke ohorere mena ka uru mai he kawenga kotahi-wāhanga nui ki te ipurangi.
Ka kitea pea ngā hekenga hiko puta noa i ngā fiusi me ngā pana hei kore taurite i te motuka me te wera nui i te pūtake o te raruraru. I mua i te whakaaro kua kitea te take, tirohia anō mā te ine i te iahiko o te whakaahua wera me te mita maha, te mita rawhi rānei. Kaua e utaina ngā ara iahiko whāngai, ngā ara iahiko peka rānei ki te rohenga mōrahi e whakaaetia ana.
Me āhei hoki ngā whārite kawenga ara iahiko ki te whakamahi i ngā āhuatanga harmonika. Ko te otinga tino noa mō te taumaha rawa ko te tohatoha anō i ngā kawenga ki waenga i ngā ara iahiko, te whakahaere rānei i te wā e puta mai ai ngā kawenga i te wā o te tukanga.
Mā te whakamahi i te pūmanawa e pā ana, ka taea te tuhi i ia raruraru e whakapaetia ana ka kitea mā te whakamahi i tētahi pūrere whakaahua wera ki roto i tētahi pūrongo kei roto ko tētahi whakaahua wera me tētahi whakaahua matihiko o ngā taputapu. Koinei te huarahi pai ki te whakapuaki i ngā raruraru me te whakaaro ki ngā whakatikatika.
