Me pēhea te mahi a te pūnaha hiko DC?

E rua ngā irahiko o te mana DC, he pai, he kino. He teitei te pūmanawa o te irahiko pai, ā, he iti te pūmanawa o te irahiko kino. Ina honoa ngā irahiko e rua ki te ara iahiko, ka taea te pupuri i te rerekētanga pūmanawa pumau i waenga i ngā pito e rua o te ara iahiko, kia rere ai he iahiko mai i te pai ki te kino i roto i te ara iahiko o waho. Kāore e taea e te rerekētanga i waenga i te taumata wai anake te pupuri i te rere o te wai pumau, engari mā te awhina o te papu hei tuku tonu i te wai mai i te wāhi iti ki te wāhi teitei, ka taea te pupuri i tētahi rerekētanga taumata wai hei hanga i tētahi rere wai pumau.

E whakamahia ana te pūnaha DC i roto i ngā tipu hiko waipēhi me te wera me ngā teihana hiko rerekē. Ko te nuinga o te pūnaha DC he mea tito mai i ngā kete pākahiko, ngā taputapu utu, ngā panera whāngai DC, ngā kāpata tohatoha DC, ngā taputapu aroturuki hiko DC, me ngā whāngai peka DC. Mā te whatunga tuku hiko DC nui, tohatoha hoki e whakarato te hiko mahi haumaru me te pono mō ngā taputapu tiaki whakawhiti, te whakaweto me te kati i ngā kaiwawao ara iahiko, ngā pūnaha tohu, ngā rihi DC, ngā whakawhitiwhitinga UPSc me ētahi atu pūnaha iti.

E rua ngā mātāpono mahi, ko tētahi he whakamahi i te hiko matua hei huri i te AC ki te DC; ko tētahi he whakamahi i te DC

AC ki DC

Ina hurihia te ngaohiko matua ki te ngaohiko kua hoahoatia mā te pana whakauru, ā, ka tahuri te whakawhiti hiko, ka uru ki te ara iahiko whakapūmau-mua. Ko te ara iahiko whakapūmau-mua he whakahaere ngaohiko tuatahi i runga i te ngaohiko putanga e hiahiatia ana, ā, ko tana kaupapa he whakaiti i te whakatikatika mana-teitei. Mā te hekenga ngaohiko ngongo i waenga i te whakauru me te putanga o te ngongo ka taea te whakaiti i te whakamahinga mana o te ngongo whakahaere mana-teitei me te whakapai ake i te whai huatanga o te mahi a te pūtake hiko DC. whakapūmau i te ngaohiko. I muri i te haere i roto i te pūtake hiko kua whakaritea-mua me te tātari, ka pumau te ngaohiko i whiwhihia, ā, ka tukuna te iahiko DC me te riu iti i roto i te ngongo whakahaere mana-teitei e whakahaerehia ana e te ara iahiko whakahaere kia tika me te tere te pātai i te pēhanga o runga, ā, ka tutuki te tika me te mahi o te whakahaere ngaohiko ki te paerewa. I muri i te tātaritanga o te ngaohiko DC e te tātari 2, ka whiwhihia te mana DC putanga e hiahiatia ana e au. Hei whiwhi i te uara ngaohiko putanga, te uara iahiko pumau rānei e hiahiatia ana e au, me tauira hoki tātou me te kite i te uara ngaohiko putanga me te uara iahiko. Ā, ka tukuna atu ki te ara iahiko whakahaere/tiaki, ka whakatauritea, ka tātarihia hoki e te ara iahiko whakahaere/tiaki te uara ngaohiko putanga me te uara iahiko kua kitea ki te uara kua whakatakotoria e te ara iahiko tautuhinga ngaohiko/iahiko, ā, ka peia te ara iahiko mua-whakahaere me te ngongo whakatikatika mana-teitei. Ka taea e te pūhiko whakapūmau DC te whakaputa i ngā uara ngaohiko me iahiko kua whakatakotoria e tātou. Ā, i te wā kotahi, ina kitea e te ara iahiko whakahaere/tiaki ngā uara ngaohiko, iahiko rānei rerekē, ka whakahohehia te ara iahiko tiaki kia uru ai te pūhiko hiko DC ki te āhua tiaki.

Pūnaha hiko DC

Ka tukuna e ngā aho AC e rua te hiko kotahi (kotahi anake rānei te hiko AC e tomo mai ana) mā te pūrere whakawhiti hei tuku hiko ki ia waeine utu. Ka hurihia e te waeine utu te hiko AC toru-wāhanga whakauru ki te hiko DC, ka utua te pākahiko, ā, ka tukuna te hiko ki te kawenga pahi kati i te wā kotahi. Ka tukuna te hiko e te pae pahi kati ki te pae pahi whakahaere mā te pūrere whakaheke-iho (kāore ētahi hoahoa e hiahia ki te pūrere whakaheke-iho).

Pūnaha hiko DC

Ko ia wae aroturuki i roto i te pūnaha ka whakahaerehia, ka whakahaeretia hoki e te wae aroturuki matua, ā, ko ngā mōhiohio ka kohia e ia wae aroturuki ka tukuna ki te wae aroturuki matua hei whakahaere kotahi mā te raina whakawhitiwhiti RS485. Ka taea e te aroturuki matua te whakaatu i ngā mōhiohio maha i roto i te pūnaha, ā, ka taea hoki e te kaiwhakamahi te uiui i ngā mōhiohio pūnaha me te whakatutuki i ngā "mahi mamao e whā i runga i te mata whakaatu aroturuki matua mā te pā, te mahi kī rānei. Ka taea hoki te uru atu ki ngā mōhiohio pūnaha mā te atanga whakawhitiwhiti rorohiko manaaki i runga i te pūnaha aroturuki mamao. Haunga te wae ine whānui, ka taea hoki te whakauru i te pūnaha ki ngā wae mahi pēnei i te aroturuki whakamahana, te tirotiro pākahiko, me te aroturuki uara whakawhiti, e whakamahia ana hei aroturuki whānui i te pūnaha DC.
