Ngā āhuatanga hiko
E ai ki te kawenga hiko o te kaupapa, e whakaaro ana tā mātou kamupene ki te whakarato i te 18 MW ngā huinga whakaputa hau+6 ngā huinga o te whakakaha me te reti whakawhiti hiko (he ipu hei whakakaha ki te 10 kV)+1 huinga o te pou wāhanga iti 10 kV+1 huinga o te reti whakawhiti hiko whakaheke-iho. Mā te whāngai i ngā huinga 18 o te huinga whakaputa hau 1MW ki ngā reti whakawhiti momo pouaka e 6, ka whakanuia te ngaohiko 400 V ki te 10 kV, kātahi ka honoa ki te pou wāhanga iti 10 kV, ā, ka tukuna te hiko e te pou wāhanga iti ki te pūwero whakamatao. I taua wā anō, ka tukuna he wāhanga o te pūngao hiko ki te reti whakawhiti hiko whakaheke-iho, ka tohatohahia te pūngao hiko 400V e te reti whakawhiti hiko whakaheke-iho.
E ai ki te kawenga hiko tuturu o te kaupapa, 1~2 huinga o ngā huinga whakaputa hau 1MW （e mōhiotia ana ko pūkaha hau 1000kw） ka taea te whakaweto, ka taea hoki te whakawhiti hei whakamahi i roto i te tiaki i ngā pūkaha hiko i muri maiE taunakihia ana kia whakamahia he pūnaha whakahaere teihana mamao mō te kaupapa, hei tirotiro i te mahi motuhake a te huinga whakaputa hiko i roto i te rūma whakahaere matua. Ka whakamahia te hau para o te huinga whakaputa hiko hau mō te whakamahinga wera para, ā, kua rite te waeine 1MW ki te pane hau para DN300 me te flange.
Kotahi te pūtake hiko ngaohiko teitei e whakaratohia ana e te kaiwhakamahi ko te 10KV±5% 50HZ±0.5HZ, he pūnaha waea-toru-wāhanga-toru, ā, kāore te pūwāhi kūpapa i te whenua. Ka whakauruhia te tanumanga tika o ngā taura ngaohiko teitei kua whakakakahuhia ki te ārai.
Te whānuitanga o te hoahoa
Ko te Rōpū B te kawenga mō te hoahoa o te teihana hiko 10KV/0.4KV me te pūnaha tuku hiko me te tohatoha o te tipu wai (me te pane puranga whiwhi hiko o te kāpata e haere mai ana 10KV hei rohe), te kawenga mō te hoahoa o ngā hoahoa pūnaha hiko ngaohiko teitei me te iti, ngā hoahoa kauwhata whakahaere hiko, me te hoahoa Pūrua, te hoahoa whakatakotoranga tohutoro o ngā taputapu hiko ngaohiko teitei me te iti, me te hoahoa pouaka whakahaere ā-rohe (pou). Kāore i roto i te whānuitanga o tēnei hoahoa te tohatoha hiko o te Whakamahinga o te tipu katoa, te tuku hiko o te papu hiko matua o te pūnaha tiaki ahi, te whakamārama tūmatanui o te tipu katoa, te pūnaha rama whare, te tuku hiko ohorere o ngā miihini whakaputa hinu tīhi, me ngā pouaka tohatoha tiaki (kāpata).
Ngā mātāpono hoahoa me te whiriwhiri
(1) Me whai ngā taputapu whakahaere hiko o tēnei tipu wai kia pono, kia haumaru, kia matatau, kia ngāwari hoki te whakahaere i runga i te whakaaro kia tutuki i ngā tikanga hoahoa me ngā whakaritenga tukanga.
(2) Me whakatakoto te mana whakahaere, te ine, te tiaki me te tohu o ngā motuka me ngā taputapu hiko katoa kia rite ki ngā ture ā-motu e tika ana.
(3) Kua hangaia te pūnaha 0.4KV i roto i te wheketere hei ara iahiko takirua.
(4) Kei ngā taputapu hiko tukatuka katoa ngā pouaka whakahaere mahi ā-rohe (kāpini). Ko te taumata ātete-pahūtanga o ngā taputapu whakahaere hiko ā-rohe i ngā wāhi ātete-pahūtanga kua hangaia kia rite ki te DⅡBT4, ā, ko tōna taumata tiaki ko IP65; ko te taumata tiaki o waho o ngā taputapu whakahaere hiko i ngā wāhi kore-ātete-pahūtanga ko IP54 Hoahoa, ko te taumata tiaki o ngā taputapu whakahaere hiko o roto kua hangaia kia rite ki te IP30.
(5) Ina tīmatahia ngā motuka teitei me ngā motuka iti, me tutuki te ngaohiko pahi i te 85% o te ngaohiko whakatauranga. Nā konei, me tīmata ngā motuka ngaohiko iti me te mana whakatauranga o te 75KW me runga ake me te tīmatanga ngohengohe; ka whakamahia e te motuka matua o te pūwhakaoho hauhautanga he taputapu tīmatanga ngohengohe ngaohiko teitei.
(6) Ka whakamahia e te pūnaha ngaohiko-tiketike he taputapu tiaki rorohiko iti kua whakauruhia hei whakatutuki i ngā mahi pēnei i te tiaki whakawhiti me te ine.
(7) Ko te mana whakahaere, te tiaki me te tohu o te taputapu whakawhiti hiko-tiketike e whakamahi ana i te pūtake hiko DC o DC220V, e ahu mai ana i te mata pākahiko waikawa-mata DC kore tiaki, ā, ka tohaina te pūtake hiko DC ki te pūnaha 10KV.
(8) Ka uru te mana whakahaere o ngā taputapu hiko o ngā taputapu wai katoa me te tohu iahiko o te motuka 30KW me runga ake ki te pūnaha DCS hei whakaatu, ā, ka taea te tīmata me te whakamutu i ngā taputapu hiko katoa o ngā taputapu tukatuka i runga i te DCS i roto i te rūma whakahaere matua, ā, ka taea hoki te tīmata me te whakamutu ā-rohe. Kei roto i te rūma whakahaere matua ngā pātene whakamutu ohorere mō ngā pūwero hau whakamatao, ngā pūwero hau whāngai, ngā papu wai hurihuri, me ētahi atu.
(9) Ka tohatohahia, ka tāutahia hoki te taputapu tiaki whānui mō te rorohiko iti o te pūnaha ngaohiko reo ki runga i ia kāpata pana, ā, ka whakatūria he pūnaha aroturuki papamuri mō te rorohiko iti. Ka tohaina te pūnaha aroturuki papamuri 10KV ki te pūnaha aroturuki papamuri 35KV, ā, kāore he whakaritenga motuhake e hiahiatia ana. Ka whakatinanahia te aroturuki i ngā tawhā whakamahinga hiko o te tipu wai, te aroturuki kounga o te pūtake hiko whatunga, te mana mamao o ngā taputapu, ngā mahi ine me te whakaoho, te whakahaere pūrongo, te tātari au, ngā tatauranga, me te tuhi i ngā tawhā hiko katoa o te tipu wai.
