Me pēhea te mahi a te pauna maha-upoko? (mātāpono)

Kaituhi: Smartweigh– Taumaha Upoko Maha

He mīhini pauna maha-upoko e whakawhiti ana i te pūngao nekeneke mai i tētahi ara ki tētahi ara. Ina koa, he pūoko kaha te pauna maha-upoko e huri ana i te pūngao miihini (pēnei i te kaha tautoko, te whakahekenga, te pēhanga mahi, te taipana rānei) hei tohu hiko ka taea te ine tika. Ka rerekē te kaha pēhi o te tohu raraunga me te kaha pēhi o te kaha tuku.

E toru ngā momo pauna matua o te pauna maha-upoko i runga i te tohu raraunga putanga: te ine waipēhi, te ine hau me te ine taumaha ātete. Ko te momo pauna e whakamahia whānuitia ana i roto i te hanga ahumahi ko te pauna maha-upoko me te taumahatanga kua hangaia ki roto. Ko te pauna maha-upoko ine taumaha ātete he mea hanga ki te tinana rauemi whakarewa totoka (he "wāhanga kōwhai rapa") e whakau ana i te ine taumaha ātete.

Ko te nuinga o te wā, he mea hanga te whare ki te konumohe, ki te maitai waro, ki te pereti maitai kore waikura rānei, ā, he tino kaha engari he ngāwari te tango. Ka paku rerekē te āhua o te pauna maha-upoko ina whakamahia te pauna, engari ka hoki anō ki tōna āhua taketake puta noa, ki te kore he kawenga. Hei pai ake te urupare ki te huringa o te āhua o te tinana, ka rerekē anō hoki te āhua o te ine taumahatanga ātete.

Mā tēnei ka puta te whakawhiti ātete o te ine taumahatanga ātete, ka taea te ine tika hei whakawhiti ngaohiko whakahaere. Nā te mea he hononga pai ēnei whakawhiti i roto i te putanga ki te taumaha kupenga i tukuna, ka taea te whakatau i te taumaha kupenga o te taonga mai i te whakawhiti ngaohiko whakahaere. Me pēhea te mahi a te pauna maha-upoko? Hei whakautu i te "Me pēhea te mahi a te pauna maha-upoko?" me mārama tuatahi koe ki te "Me pēhea te mahi a te ine taumahatanga ātete?" Ko te ine taumahatanga ātete he taputapu e ine tika ana i te whakawhiti o te ātete ina tukuna he kaha.

Ko te ine taumahatanga ātete noa he mea hanga ki te mata waea angiangi rawa, he mea whakatakoto ki te tauira whatunga, ka huri te ātete waea ina tukuna te kaha taumahatanga i te taha o te tuaka kotahi. He maha ngā momo ine taumahatanga ātete hei whiriwhiri māu: Ine taumahatanga ātete rārangi: Ko te aho hiko e hono ana ki muri o te ine taumahatanga ātete he whakarara ki te taha o te ine taumahatanga ātete. Ka whakamahia tēnei hei ine tika i te taumahatanga radial me te taumahatanga piko.

Ngā ine taumahatanga ātete tapahi: Ko ngā aho hiko e hono ana ki muri o ngā ine taumahatanga ātete kua whakatakotoria ki ngā taha e rua o te anga pēhanga mahi i te kokonga 45°. Ka whakamahia tēnei hei ine tika i te taumahatanga tapahi. Ko ngā ine taumahatanga ātete ka whakamahia whānuitia me te maha o ngā ine taumahatanga ātete hei whakapai ake i te tika.

Kotahi te ine taumahatanga ātete whakakaha mana mamati e kiia ana he piriti hauwhā, e rua ngā ine taumahatanga ātete whakakaha mana mamati e kiia ana he piriti haurua, ā, e whā ngā ine taumahatanga ātete whakakaha mana mamati e kiia ana he piriti katoa. Kāore ngā whakawhiti ātete ine taumahatanga ātete i te rite ki te taumaha i tētahi pākahiko ka taea te whakahou i roto i tētahi kaha tautoko. Mā te tawhiti taumahatanga ka ngawari, ka roa te ine taumahatanga ātete, ka hiki ake i te ātete.

Mā te kaha whakawhāiti ka whakapotohia te matotoru o te ine taumahatanga ātete, ā, ka whakaitihia te ātete. Ka tāpirihia te ine taumahatanga ātete ki te tuara angiangi (te pūmau), e piri tonu ana ki te waeine pauna, kia taea ai e te ine taumahatanga ātete te rongo i te kaha taumahatanga o te pauna maha-upoko. He tino iti te whakawhiti ātete i ine tikahia e te ine taumahatanga ātete kotahi, tata ki te 0.12°.

Ka piki ake te aro o te waeine kawenga me te maha o ngā ine taumahatanga e tukuna ana. Ko te huarahi pai ki te huri i tēnei nekehanga iti hei mea e taea ake ai te whakaaro ko te hono atu i a rātou hei piriti pauna atamai. Ngā momo ine taumahatanga ātete Ka whakatakotoria ngā ine taumahatanga ātete ki ngā aronga rerekē, ā, ko te mea pono kei roto i te momo kaha e ine tika ana.

Ka ine tikahia te taumahatanga piko, te taumahatanga kutikuti, te taumahatanga radial, te taipana me te pēhanga mahi mā te whakamahi i tētahi whakaritenga whakaaro motuhake o ngā ine taumahatanga ātete. E whā ngā ātete whakataurite kei roto i te ara iahiko piriti pauna atamai, ā, e whakamahi ana i te ngaohiko whakahaere whakaohooho e mōhiotia ana, e whakaaturia ana i raro nei: Ko te 5 te ngaohiko whakahaere pumau e mōhiotia ana, ā, ka ine tikahia te VO. Mena he taurite ngā ātete katoa, ko te tikanga he kore a R1/R2R3/R4, kātahi ko te VO.

Mena he panoni kei roto i tētahi o ngā uara ātete, ka puta he panoni ki te VO, ka taea te ine tika me te whakaatu mā te whakamahi i te ture a Ohm. E whakanui ana te Ture a Ohm ko te nui o te iahiko (I, i roto i ngā amperes) e haere ana i roto i tētahi kaiārahi hiko i waenga i ngā pūwāhi e rua he hononga pai ki te ngaohiko whakahaere (V) i waenga i ngā pūwāhi e rua. Ka whakaurua te ātete (R, i ine tika i roto i ngā ohms) hei whakamāramatanga taurangi i roto i tēnei hononga, ā, kāore he pānga ki te rere o te iahiko.

Ko te ture a Ohm e whakaatuhia ana i roto i te tātai I=V/R. Ina whakamahia ki ngā rīpene pepa e 4 o te ara iahiko hiko o te piriti pauna atamai, ko ngā whārite ka puta ko: I roto i te pauna maha-upoko, ka whakakapia tēnei ātete e te ine taumahatanga ātete i roto i te whakakapinga o te kaha tautoko me te ine tika o te whakahekenga. Ina tukuna te kaha ki te pākahiko ka taea te whakahou kua paunatia, ka huri ngā ātete i roto i ia ine taumahatanga ātete, ā, ka ine tika te VO.

Mai i ngā raraunga kua puta mai, ka taea te tautuhi ngāwari i te VO mā te whakamahi i te pūnaha whārite i runga ake nei.
