He aha te rerekētanga i waenga i te kaiwawao hiko ngaohiko teitei me te pana wehe?

Ko te kaiwawao hiko hiko teitei (te pana hiko teitei rānei) te taputapu whakahaere mana matua o te teihana hiko, me ngā āhuatanga tinei pewa, ina mahi noa te pūnaha, ka taea te tapahi me te kore kawenga me te iahiko kawenga mā roto i te raina me ngā taputapu hiko rerekē; ina puta he hapa i roto i te pūnaha, ka taea e ia te tapahi tere i te iahiko hapa, kia kore ai e whakawhānui i te whānuitanga o te aituā.

Kāore he taputapu tinei hiko āwhata o te pana momotu. Ahakoa e kī ana ngā ture ka taea te whakahaere i te wā e iti iho ana te iahiko kawenga i te 5A, kāore i te nuinga o te wā ka whakahaerehia me te kawenga. Heoi, he hanganga māmā te pana momotu, ā, ka kitea tōna āhua mahi i te tirohanga tuatahi mai i te āhua. He wāhi momotu mārama kei te wā tiaki.

Ko te kaiwawao hiko e whakamahia ana ko te "pana", ko te pana momotu e whakamahia ana ko te "paraikete maripi", he maha ngā wā ka whakamahia ngātahitia ēnei e rua. Ko ngā rerekētanga i waenga i te kaiwawao hiko ngaohiko teitei me te pana momotu koia ēnei:

1) Ka taea te pakaru te pana kawenga ngaohiko teitei me te kawenga, me te mahi pewa tinei-ake, engari he iti rawa, he iti hoki te kaha o tana pakaru.

2) Ko te pana momotu hiko ngaohiko teitei te tikanga kāore i te pakaru te kawenga, kāore he hanganga uhi pewa, kei reira anō hoki te pana momotu hiko ngaohiko teitei ka taea te pakaru te kawenga, engari he rerekē te hanganga mai i te pana kawenga, he tino māmā.

3) Ka taea e te pana kawenga ngaohiko teitei me te pana momotu ngaohiko teitei te hanga i tētahi pūwāhi pakaru mārama. Ko te nuinga o ngā kaiwawao hiko ngaohiko teitei kāore he mahi wehewehe, ā, he iti noa ngā kaiwawao hiko ngaohiko teitei he mahi wehewehe.

4) Kāore he mahi tiaki a te pana momotu hiko teitei, ko te tiaki a te pana kawenga hiko teitei he tiaki fiusi noa iho, he tere te pakaru me te nui o te iahiko.

5) Ka tino teitei te kaha pakaru o ngā kaiwawao hiko hiko teitei i roto i te tukanga hanga. Ko te nuinga o te wā ka whakawhirinaki ki te whakawhiti hiko me ngā taputapu tuarua hei tiaki. Ka taea te whai i te tiaki ara iahiko poto, te tiaki taumaha, te tiaki turuturu me ētahi atu mahi.

Te whakarōpūtanga o ngā tikanga whakahaere pana

1. Te whakarōpūtanga o te tikanga whakahaere pana

Inaianei kua kitea e tātou te wāhanga matua o te pana, arā, he nui ake te hinu (ngā tauira tawhito, kāore i te kitea), he iti ake te hinu (kei te mau tonu ētahi teihana kaiwhakamahi), he SF6, he korehau, he GIS (ngā taputapu hiko whakakotahi) me ētahi atu momo. E pā ana ēnei ki te reo whakakorikori o te pana. Ki a tātou, ko te tuarua, he hononga tata ko te tikanga whakahaere o te pana.

Ka taea te wehewehe i te momo tikanga ki te tikanga mahi hikohiko (he tawhito rawa, ko te tikanga kei roto i te hinu, i te iti iho rānei o te hinu he mea rite ki tēnei); Tikanga whakahaere puna (ko te mea tino noa i tēnei wā, ko te SF6, te korehau, ko te GIS he mea rite ki tēnei tikanga); Nō nā tata nei i whakauru mai a ABB i tētahi momo hou o te kaiwhakahaere aukume tuturu (pēnei i te VM1 korehau).

2. Tikanga whakahaere hikohiko

Ko te tikanga whakahaere hikohiko e whakawhirinaki katoa ana ki te momi hikohiko e whakaputaina ana e te ia kati e rere ana i roto i te koiri kati hei kati me te pēhi i te puna whakamuri. Ko te nuinga o te whakamuri e whakawhirinaki ana ki te puna whakamuri hei whakarato pūngao.

Nō reira, he iti te ia o te whakamutu o tēnei momo tikanga whakahaere, engari he tino nui te ia kati, ka taea e te ia tere te eke ki te neke atu i te 100 ampere.

Koia te take me whakatuwhera, me kati hoki te pūnaha hiko ā-auau o te teihana hiko hei whakahaere i te pahi. Ko te whaea kati te kaihomai i te mana kati, ā, ko te whaea whakahaere te kaihomai i te hiko ki te porowhita whakahaere.

Kei te whakairihia tika te pahi kati ki runga i te kete pākahiko, ko te ngaohiko kati ko te ngaohiko o te kete pākahiko (te nuinga o te 240V), ko te whakamahinga o te pānga tukunga pākahiko hei whakarato i te iahiko nui i te wa e kati ana, ā, he tino koi te ngaohiko i te wa e kati ana. Ā, ko te pahi whakahaere kei roto i te mekameka silicon heke me te whaea e hono tahi ana (te nuinga o te whakahaere i te 220V), kāore te kati e pā ki te pumau o te ngaohiko pahi whakahaere. Nā te mea he tino nui te iahiko kati o te tikanga whakahaere hikohiko, ehara te ara iahiko kati tiaki i te tika mā te koiri kati, engari mā te hoapā kati. Kei te hono tika te ara iahiko haerenga ki te koiri haerenga.

Ko te momo ngaohiko o te koiri whakapā kati he momo ngaohiko whānui, he nui te uara ātete (he torutoru K). Ina honoa te parenga ki tēnei ara iahiko, me aro ki te kati kia mau tonu te tīmatanga whānui. Engari ehara tēnei i te raruraru, mā te pakaru ka taea te tīmata i te TBJ, nō reira kei reira tonu te mahi ārai-peke. He roa te wā kati o tēnei momo tikanga (120ms~200ms) me te wā whakatuwhera poto (60~80ms).

3. Te tikanga whakahaere o te puna

Ko tēnei momo tikanga te tikanga e whakamahia whānuitia ana i tēnei wā, ko tōna katinga me tōna whakatuwheratanga e whakawhirinaki ana ki te puna hei whakarato pūngao, ko te koiri katinga peke anake e whakarato ana i te pūngao hei kukume i te pine tūnga puna, nō reira kāore i te nui te ia katinga peke. Ka pēhia te rokiroki pūngao puna e te motuka rokiroki pūngao.

Porowhita tuarua o te kaiwhakahaere rokiroki pūngao puna

Mō te tikanga whakahaere rapa, ko te pahi kati te nuinga e tuku hiko ana ki te motuka rokiroki pūngao, ā, kāore i te nui te iahiko, nō reira kāore he rerekētanga nui i waenga i te pahi kati me te pahi whakahaere. Hei tiaki i tōna whakaritenga, i te nuinga o te wā kāore he take motuhake ki te aro ki te wāhi.

4. Kaiwhakahaere aukume tuturu

Ko te kaiwhakahaere aukume tuturu he tikanga i whakamahia e ABB ki te mākete ā-rohe, i whakamahia tuatahitia ki tana kaiwawao ara iahiko korehau VM1 10kV.

He rite tonu tōna kaupapa ki te momo hikohiko, he mea hanga te rakau taraiwa mai i te rauemi aukume tuturu, he aukume tuturu e karapoti ana i te koiri hikohiko.

I raro i ngā āhuatanga noa, kāore te koiri hikohiko e utua ana, ina whakatuwheratia, ina kati rānei te pana, mā te whakarerekē i te polarity o te koiri mā te whakamahi i te mātāpono kukume aukume, te mātāpono whakahē rānei, ka whakatuwhera, ka kati rānei te puku.

Ahakoa ehara tēnei iahiko i te iti, ka "penapenahia" te pana e tētahi pūnga iahiko nui te kaha, ka tukuna hei whakarato i tētahi iahiko nui i te wā e mahi ana.

Ko ngā painga o tēnei tikanga he iti te rahi, he iti ake ngā wāhanga mīhini tuku, nō reira he pai ake te pono i te tikanga mahi rapa.

I te taha o tā mātou taputapu tiaki, ka whakahaerehia e tā mātou koropiko whakataka he whakawhiti ātete-teitei e hiahia ana kia whakaratohia e mātou he pao mahi.

Nō reira, kāore e taea te tīmata i te pana, te pupuri i te koropiko, kāore hoki e taea te tīmata i te tiakitanga o te peke (te tikanga tonu me te peke).

Heoi, me mōhio, nā te nui o te ngaohiko whakahaere o te whakawhiti ā-pūngao totoka, ka honoa te hoahoa tuku iho TW kino ki te ara iahiko kati, e kore ai e mahi te whakawhiti ā-pūngao totoka, engari ka kore pea e tīmata te whakawhiti ā-pūngao tūnga nā te nui rawa o te ngaohiko wāhanga.

1. Puoto whakamahana o runga (me te rūma tinei-āwhata korehau)

2. Whakahekehia te rango whakamātao

3. Kakau whakatuwhera ā-ringa

4. Chassis (tikanga whakahaere aukume tuturu kua hangaia)

Whakawhiti hiko

6. I raro i te waea

7. Whakawhiti iahiko

8. I te ipurangi

Mō tēnei āhuatanga i tūponohia i te parae, ka kitea te tukanga tātari me te tukatuka motuhake i te wāhanga take patuiro o tēnei pepa, he whakaahuatanga taipitopito anō hoki.

Kei Haina anō hoki ngā hua o te pūnaha whakahaere aukume tuturu, engari kāore anō kia eke te kounga ki te paerewa i mua. I ngā tau tata nei, kua āta kawea mai te kounga ki te mākete. Ina whakaarohia te utu, ko te tikanga kāore he kaha o te pūnaha aukume tuturu o te whare, ā, ka tukuna tika mai te iahiko e te pahi kati.

Ko te hononga whakaweto-whakakā (te momo iahiko e tīpakohia ana i te nuinga o te wā) e peia ana e tā mātou tikanga whakahaere, ā, ka taea te tīmata i te pupuri me te ārai-peke.

5. Momo "whakawhiti" FS me ētahi atu

Ko ngā mea kua whakahuatia ake nei ko ngā kaiwawao hiko (e mōhiotia whānuitia ana ko ngā pana), engari tera pea ka tūtaki tātou ki ngā mea e kiia nei e ngā kaiwhakamahi he pana FS i roto i te hanganga o ngā tipu hiko. Ko te pana FS he whakarāpopototanga mō te pana uta + piu tere.

Nā te mea he nui ake te utu o te pana, ka whakamahia tēnei ara iahiko FS hei penapena utu. Ka tangohia te iahiko noa e te pana kawenga, ā, ka tangohia te iahiko hapa e te fiusi tere.

He mea noa tēnei momo ara iahiko i roto i te pūnaha tipu hiko 6kV. He mea nui te tiaki i te taha o tēnei ara iahiko hei ārai i te hinganga, hei tuku rānei i te tango tere o te iahiko whakakorikori mā te whakaroa ina nui ake te iahiko hapa i te iahiko pakaru e whakaaetia ana o te pana kawenga. Tērā pea ētahi kaiwhakamahi tipu hiko kāore e hiahia ki te tiaki i te porowhita pupuri.

Nā te kounga iti o te pana, tērā pea kāore te hononga āwhina i te tūnga, ā, ina tīmata te ara iahiko pupuri, me whakawhirinaki ki te hononga āwhina o te kaiwawao kia tuwhera i mua i te hokinga mai, ki te kore ka tāpirihia te iahiko kati peke ki te pōkai kati peke kia pau rā anō te pōkai.

Kua hangaia te koiri kati peke kia whakakahangia mō te wā poto. Mēnā ka tāpirihia te iahiko mō te wā roa, ka ngāwari te mura. Ā, me whai porowhita pupuri tātou, ki te kore ka tino ngāwari te mura o ngā hononga tiaki.

Ae, ki te tohe te kaiwhakamahi mara, ka taea hoki te tango i te koropiko pupuri. Ko te tikanga māmā ko te tapahi i te aho i runga i te papa ara iahiko e pupuri ana i te hononga tuwhera noa o te whakawhiti me te wahine mana pai.

I te pae patuiro, me aro nui ki te mea kei te whakaweto, kei te mahi te pana, kei te whakaweto te tohu tūranga. (haunga te puna kāore i te penapena i te pūngao, i tēnei wā ka whakaatuhia e te panui te whakaoho pūngao kāore i te penapena i te puna). Me whakaweto tonu te mana whakahaere kia kore ai e tahuna te koiri pana. He kaupapa matua tēnei hei maumahara tonu.
