Ko te kaitahuri auau – te puku auau taurangi rānei (VFD) – he taputapu hiko e huri ana i te iahiko me tētahi auau ki tētahi iahiko me tētahi atu auau. He rite tonu te ngaohiko i mua me muri i te huringa auau. Ko ngā kaitahuri auau te tikanga e whakamahia ana hei whakahaere i te tere o ngā motuka e whakamahia ana hei taraiwa i ngā papu me ngā pā.
He taputapu hiko te kaitahuri auau e huri ana i te iahiko me tētahi auau ki tētahi atu iahiko me tētahi atu auau. He rite tonu te ngaohiko i mua me muri i te huringa auau. Ko ngā kaitahuri auau te tikanga e whakamahia ana hei whakahaere i te tere o ngā motuka e whakamahia ana hei taraiwa i ngā papu me ngā pā.
E whakaatu ana te tauira e whai ake nei i te mahi a tēnei:
Ka whakaratohia he iahiko 400 VAC, 50 Hz ki tētahi pā hau. I tēnei auau (50 Hz), ka taea e te pā hau te oma i tētahi tere. Hei whakatere i te oma o te pā hau, ka whakamahia he kaitahuri auau hei whakanui ake i te auau ki (hei tauira) 70 Hz. Tērā atu rānei, ka taea te huri i te auau ki te 40 Hz mēnā ka pōturi te oma o te pā hau.
Kāore koe e hiahia ki te mono i ngā taputapu ki te pūtake hiko hē, kei tūpono koe ki te tuku i te paoa kia puta mai i ō taputapu. Ā, he rite te paoa ki te "genie i roto i te pounamu", ina puta mai i te taputapu hiko, kāore e taea te whakahoki ki roto……Kāore e taea e ngā taputapu nui ake, ā-wāhanga-toru te mahi i runga i te auau hē nā te mea ka taea e te auau hē te whakararu, te pakaru rānei i te taputapu i te wā wawe.
Nō reira, me pēhea te wehewehe i tētahi kaitahuri auau tūturu e whakamahia ana i runga i te mīhini horoi waka, koinei te kaupapa matua.
Ina hoki, e kī ana te nuinga o ngā kaihokohoko he kaitahuri tā rātou, ā, ka whakamahia ki te mīhini horoi waka. Engari ehara i te kaitahuri auau tūturu e taea ai te whakarerekē i te ngaohiko me te tere neke o te mīhini horoi waka. I te nuinga o te wā, he motuka iti 0.4 e whakamahia ana ki te tinana neke, ā, kāore e taea te whakarite i ngā tauira rerekē he pēhanga teitei me te iti o te wai rehu me te tere teitei me te iti o ngā pā. He aha te mea kino atu, ki te kore he kaitahuri auau, ina tīmata te mīhini ki te mahi, ko te iahiko inamata he 6-7 ngā wā i te iahiko noa, ka ngāwari te pakaru o te hāora me te maumau hiko.
Ka whakamahia e te mīhini horoi waka CBK te hangarau whakawhiti auau 18.5kw hei taraiwa, ā, nā te pēhanga teitei me te iti o te wai i ringihia me te tere teitei me te iti o ngā pā, ka penapenahia te whakapaunga hiko neke atu i te 15%, ko te tikanga ka taea e te rangatira te whakarite i tētahi tukanga e hiahia ana ia. Nō reira, ka taea e te mīhini horoi waka CBK te whakaiti i te hiahia mō te tiaki me ngā utu e haere tahi mai ana.
I te nuinga o te wā, ko ngā mea katoa he motuka kei roto, me whai kaitahuri auau, ā, ka taea e te mīhini horoi waka CBK te mahi i tēnā.
