He aha te hiranga o te VPD mō te hanga hiko whakawhiti hiko, ā, ko wai ngā kaiwhakarato matua i Haina?
Ko te Whakamaroke Āhuatanga Kohu (VPD) tētahi o ngā tukanga tino nui i roto i te hanga whakawhiti hiko nā te mea ka whakarite kia tangohia katoatia te makuku mai i te pūnaha whakamarumaru (te nuinga ko te pepa cellulose me te papa perehi). Ko te makuku tētahi o ngā hoariri nui o te pono o te whakawhiti hiko.
Kei raro nei ngā take matua he aha te hiranga o te VPD:
- Ka tino whakaitihia te kaha o te ārai i te makuku
Ko ngā pūnaha whakamahana whakawhiti he mea hanga te nuinga mai i ngā rauemi cellulose (pepa, papa pēhi) me te hinu whakawhiti.
- Ahakoa te 1–2% o te makuku i roto i te cellulose ka taea te whakaiti nui i te kaha dielectric.
- Ka taea e te wai te whakaputa i te rerenga wāhanga, te rahunga o te whakamarumaru, me ngā hapa o roto.
Ka whakaitihia e te VPD te nui o te makuku i roto i te whakamarumaru hiko ki raro iho i te 0.5%, e hiahiatia ana mō ngā whakawhiti hiko ngaohiko teitei me ngā whakawhiti hiko tino teitei.
- Ka whakaroa i te roanga o te wā o te Transformer
Ka tere ake te koroheketanga o te cellulose e te makuku mā te hydrolysis.
Ngā pānga o te makuku:
- Te tere ake o te pakaru o te mekameka polymer
- Te whakaiti i te taumata o te polymerization (DP)
- Te roa o te ora o te whakawhiti
Mā te whakamaroke tika mā te VPD ka roa ake te ora o te whakawhiti hiko mai i te 20 tau ki te 40+ tau i te nuinga o te wā.
- He Tere Rawa Atu i te Whakamaroke Koreutu Tikanga
He puhoi te whakamaroke i te hau wera tuku iho, i te korehau rānei, nā te mea kāore e whai hua te whakawhiti wera i roto i te takai.
Ka whakamahia e te VPD te whakarewa mimiti (te nuinga o te hinuhinu) e:
- Ka whakapūmau i runga i te mata whakamahana makariri
- Ka tukuna te wera huna nui
- Ka uru hōhonu ki roto i te kopikopiko
Hua:
- Whakamahana ōrite
- Tere rawa te whakamaroke
Te whakataurite wā noa:
Tikanga Whakamaroke Te Wā Noa
Te whakamaroke i te hau wera 10--20 rā
Whakamaroke i roto i te mīhini horoi 5--10 rā
VPD 2--5 rā
- Te Whakamaroke Hōhonu o ngā Hanganga Whakamaroke Matotoru
He matotoru rawa ngā hanganga whakamarumaru o ngā whakawhiti hiko nui:
- Ngā rango papa pēhi matotoru
- Ngā takai maha-paparanga
- Ngā huihuinga matua-kōiri nui
Mā te VPD ka hohonu te whakamahana, ka taea ai te heke o te makuku mai i ngā paparanga whakamarumaru o roto, he mea uaua tēnei ki ētahi atu tikanga whakamaroke.
- He mea nui mō ngā Whakawhiti Ngaohiko Teitei
Mō ngā whakawhiti hiko ≥220 kV, inā koa ko te 400 kV / 500 kV / 765 kV, ka kiia te VPD he taputapu paerewa ā-umanga.
Ko te nuinga o ngā kaihanga nui e whakamahi ana i tēnei, pērā i:
- Siemens Energy
- Hitachi Energy
- GE Vernova
- TBEA
Ki te kore e maroke tika, kāore e taea e te whakawhiti hiko te tu atu i ngā whakamātautau ātete i te pehanga me te AC.
- Whakapai ake i te Whai Hua o te Whakaputa
Ka whakapai ake hoki ngā pūnaha VPD i te whai huatanga o te hanga:
- He poto ake te huringa whakaputa
- He kounga whakamātao pumau ake
- He iti ake te mōrearea o te korenga o te whakamātautau wheketere
Mō ngā wheketere e hanga ana i ngā whakawhiti hiko nui, ka noho te VPD hei arai whakaputa, nō reira he mea nui tōna pono me tōna kaha.
I ngā kupu māmā noa iho:
Mena ko te takai te "ngakau" o te whakawhiti hiko, ko te maroke o te whakamarumaru te "ora".
Ko te VPD te huarahi tino whai hua hei whakapūmau i taua oranga.
I te mea i kōrero koe i mua ake nei kei te mahi koe i ngā tono tono taputapu whakawhiti hiko mō ngā kaupapa Siemens, ko ngā taputapu VPD tētahi o ngā mīhini tino uara, tino arotakehia hoki i roto i ngā haumitanga ki te wheketere whakawhiti hiko.
Ki te hiahia koe, ka taea hoki e au te whakamārama:
- He aha i pai ake ai te VPD i te Hot Oil Spray (HOS) i te nuinga o ngā wheketere whakawhiti hiko?
- Ngā tawhā hangarau matua e arotakehia ana e ngā kiritaki ina tono ana i ngā pūnaha VPD
- Ko ēhea ngā kamupene e whakahaere ana i te mākete taputapu VPD puta noa i te ao?
He mea tino nui ēnei āhuatanga i roto i ngā tono tono taputapu whakawhiti.
I roto i te umanga whakawhiti hiko, he iti noa iho, he motuhake hoki te mākete taputapu Whakamaroke Wāhanga Kohu (VPD), he iti noa iho ngā kaiwhakarato wheako o te ao. Ko te tikanga, ka whiriwhiria e ngā kaihanga whakawhiti hiko ngā kaiwhakarato he roa ngā tohutoro me te hangarau whakamaroke kua whakamātauhia, nā te mea he mea nui te VPD mō te kounga o te whakamahana.
Kei raro nei tētahi tirohanga ā-ahumahi mō ngā kaiwhakarato matua.
