He otinga whānui te pūnaha whakaoho kore paraihe mō te tuku i te au hiko ā-marae ki ngā kaihanga hiko tukutahi i roto i ngā tipu hiko wai, ngā teihana hiko wera, me ngā pūnaha hiko ahumahi. Mā te whakakore i ngā paraihe me ngā mowhiti paheke, ka tino whakapai ake i te pono, ka whakaiti i ngā whakaritenga tiaki, ā, ka whakarei ake i te haumaru mahi.
I ēnei rā, he paerewa ngā pūnaha whakaoho kore paraihe i roto i ngā waeine whakaputa wai nui, waenga hoki, nā te mea he māmā noa iho te miihini me te roa o te ora mahi.
1. Whirihoranga Taketake
Ko te pūnaha whakaoho kore paraihe noa ko:
Kaiwhakahaere Ngaohiko Aunoa (AVR)
AC Exciter
Huinga Whakatikatika Hurihuri (Pītiti Diode)
Te Hurihanga Marae Rotora o te Pūkaha Matua
Ka whakanohoia ngā wāhanga hurihuri katoa ki runga i te pou kotahi me te whakaputa hiko matua, ka hanga he hanganga whakauru.
2. Te Mātāpono Mahi
Ko te mahi a te pūnaha whakaoho kore paraihe penei:
2.1 Te Kimi i te Ngaohiko
Ka aro turuki tonu te AVR i te ngaohiko o te pito o te whakaputa hiko.
2.2 Mana Whakahaere Mara Whakahihiri
Mena ka rerekē te ngaohiko mai i te uara kua whakaritea, ka whakatikatika te AVR i te iahiko DC e tukuna ana ki te takai mara whakahihiri.
2.3 Whakatupuranga AC
Ka whakaputahia e te whakaoho AC te iahiko whakawhiti-wāhanga-toru i roto i tōna anga.
2.4 Te Whakatikatika Hurihuri
Ka whakatikatikaina te putanga AC toru-wāhanga ki te DC mā te piriti diode hurihuri e mau ana ki runga i te kakau.
2.5 Te Tukunga o te Papa Matua
Ka uru tika te iahiko DC kua whakatikatikaina ki roto i te takai rotor o te whakaputa hiko matua, ka whakatū i te papa aukume e hiahiatia ana mō te whakaputa hiko.
Nā te mea ka puta te whakatikatika i runga i te kakau hurihuri, kāore he take mō ngā paraihe, mō ngā mowhiti paheke rānei.
3. Ngā Āhuatanga Hangarau Matua
3.1 Hanganga Kore Paraihe
Ko te korenga o ngā paraihe ka whakakore i te pakaru o te waku, te puehu waro, me ngā raruraru mura.
3.2 Te Pono Nui
Mā te iti ake o ngā wāhanga e pā ana ki te mīhini, ka iti ake ngā reiti rahunga o te pūnaha, ā, ka roa ake ngā wā mahi.
3.3 Te iti o te tiaki
Ko te tiaki o ia rā ko te tirotiro i ngā diode hurihuri me ngā hononga hiko.
3.4 Mahi Hihiri Pai
Ahakoa kāore i te tere rite ki ngā pūnaha whakaoho pateko, ka whakaratohia e te whakaoho kore paraihe he urupare e tika ana mō te nuinga o ngā whakamahinga wai me ngā tono ahumahi.
4. Ngā Painga i roto i ngā Whakamahinga Pūngao Wai
I roto i ngā tipu hiko wai, inā koa ko ngā mea kei ngā rohe maunga, kei ngā rohe tūmatanui rānei, he nui ngā painga whakahaere o te whakaoho kore paraihe:
Te whakaiti i te mahi tiaki
Te mahi pumau mō te wā roa
Te whakapai ake i te haumaru mahi
Teitei o te urutau ki ngā piki me ngā heke o te kawenga
Mō ngā teihana wai e rere ana i te awa, mō ngā teihana wai waenga-upoko rānei, ina koa he mea nui te pono me te ngāwari, ko ngā pūnaha kore paraihe te whiringa pai.
5. Ngā Mahi Tiaki me te Aroturuki
Ko ngā pūnaha whakaoho kore paraihe hou he rite tonu ki ngā āhuatanga tiaki matatau, tae atu ki:
Te aukati i te nui rawa o te whakaohooho
Te aukati i te iti o te whakaohooho
Te parenga o te aukume mara
Te parenga ngaronga-o-te-whakaohooho
Te kimi rahunga o te diode
Te aroturuki i te pāmahana o te rotor
Ka whakarei ake ngā AVR mamati i te tika o te whakahaere me te tātaritanga pūnaha, ka whakapai ake i te haumaru whānui o te waeine.
6. Ngā Auahatanga Whakawhanake
Kei te whanake haere ngā pūnaha whakaoho kore paraihe hou ki:
Mana AVR matihiko katoa
Hanganga whakahaere taurite
Te aroturuki ipurangi me te tātaritanga mamao
Te whakaurunga ki ngā pūnaha aunoatanga tipu
I te mea ka kaha haere ngā whakaritenga whatunga me te piki haere o te urunga mai o te hiko whakahou, ka nui haere te hiranga o te mana whakahaere whakaoho atamai ki te pumau o te ngaohiko me te whakahaere mana tauhohe.
Mā te pūnaha whakaoho kore paraihe ka whakaratohia he otinga pakari, he ngāwari hoki te tiaki mō te tuku mara whakaputa hiko tukutahi. Ko tōna hoahoa mīhini māmā, me te hangarau whakahaere mamati hou, ka whakarite kia pono, kia haumaru, kia whai hua hoki te mahi.
I roto i ngā tono hiko wai me ngā tono whakaputa ahumahi, ko te whakaoho kore paraihe tetahi o ngā otinga whakaoho tino whai hua me te whānui o te whakamahi puta noa i te ao.
