Pūrere Ārai Ngaru (SPD): Te Āraitanga Hiranga mō ngā Pūnaha Hiko Hou

I tēnei ao hiko me te hononga e piki haere ana i ēnei rā, kei te tūpono tonu ngā pūnaha hiko ki ngā mōrearea pēnei i tengā whiunga uira, ngā ngaru whakawhiti, me ngā ngaohiko tereKa taea e ēnei pikinga ohorere o te ngaohiko te whakararuraru i ngā taputapu hiko, te whakararuraru i ngā mahi, me te arahi ki te wā whakatā utu nui. Koinei te wāhi eNgā Pūrere Ārai Ngaru (SPD)whai wāhi nui.

He aha te SPD?

A Pūrere Ārai Ngaru (SPD)kua hangaia heite tiaki i ngā pūnaha hiko me ngā taputapu mai i ngā ngaohiko teremā te huri haumaru i te kaha o te ngaru nui ki te whenua. Ina puta he ngaru, ka tere tonu te urupare a te SPD, ka whakawhāiti i te ngaohiko ki te taumata haumaru, ā, ka ārai i te kino o ngā taputapu hono.

He aha te hiranga o ngā SPD?

He mea nui ngā SPD hei whakarite kia:

• Te Tiaki TaputapuTe tiaki i ngā taputapu hiko me ngā taputapu hiko tairongo mai i ngā pikinga ngaohiko
• Te Pono o te PūnahaTe whakaiti i te wā kore mahi i puta mai i ngā hapa e pā ana ki te ngaru hiko
• Te Whakapūmau HaumaruTe ārai i ngā tūponotanga kino pēnei i te pakaru o te whakamarumaru, te mōrearea ahi rānei
• Te Whai Hua o te UtuTe whakaiti i ngā utu whakatikatika me te whakakapinga

Me ngā wā urupare i inehia i roto ingā nanohekona, ka mahi ngā SPD hei rārangi parepare tere, pono hoki mō ngā pūnaha hiko.

Ngā horopaki tono noa

E whakamahia whānuitia ana ngā SPD puta noa i ngā ahumahi me ngā taiao, tae atu ki:

• Ngā whare ahumahi me ngā whare hanga
• Ngā whare arumoni me ngā tari
• Ngā pūnaha hiko kāinga
• Ngā pokapū raraunga me ngā pūnaha whakawhitiwhiti kōrero
• Ngā pūnaha pūngao hou pērā i ngā whakaurunga pūngao rā (PV)
• Ngā whatunga tohatoha hiko

Ngā mea e ruaNgā pūnaha AC me DCme whai ārai ngaru hiko, inā koa i ngā taiao e pāngia ana e te uira, e ngā mahi whakawhiti pinepine rānei.

Ngā Otinga SPD Hiko Mutai

Hei kaihanga ngaio o ngā taputapu hiko iti-ngaohiko,Rōpū Hiko Mutaie tuku ana i te whānuitanga katoa oNgā Pūrere Tiaki Ngaru AC me DC, i hangaia hei whakarato i te tiakitanga pono me te whai hua mō ngā momo tono.

Raupapa AC SPD

Mutai'sAC SPDhe pai ngā hua mōNgā pūnaha 220V/380V, e whakarato ana i te parenga pakari mai i ngā ia ngaru e puta mai ana i te uira, i ngā raruraru whatunga rānei.

Ko ngā āhuatanga matua ko:

• Te aukume tukunga mōrahi (Imax)tae atu ki100kA (8/20μs)
• Iahiko tukunga ingoa (In)tae atu ki60kA (8/20μs)
• Taumata tiaki iti (Ki runga)mai i1.5kV ki te 2.5kV
• Wā urupare tereiti iho i te20ns
• He iti te rerenga o te aumō te whakapakari i te pumau o te pūnaha

He pai rawa atu ēnei SPD mō te tiakingā panera tohatoha, ngā kāpata hiko, me ngā pūnaha hiko whare.

Raupapa SPD DC

Mutai'sDC SPDhe mea hanga motuhake ngā hua mōNgā pūnaha DC, inā koa i roto ingā tono photovoltaic solar (PV)me ētahi atu pūnaha pūngao hou.

Ko ngā āhuatanga matua ko:

• Ngaohiko whakahaere tonu mōrahi (Uc)tae atu kiDC1500V
• Iahiko tukunga ingoa (In) of 20kA (8/20μs)
• Te aukume tukunga mōrahi (Imax) of 40kA (8/20μs)
• Taumata parenga (Ki runga)≤3.2kV
• Te wā urupare tino tere of 25ns
• Hototahi kiTāutanga o te reera DINmō te whakaurunga ngāwari

He pai te tiaki a ēnei taputapu i teNgā pūnaha PV, ngā pūnaha tohatoha DC, me ngā whakaurunga rokiroki pūngaomai i ngā ngaru rangitahi.

Te Tiakitanga Pono Ka Taea e Koe te Whakawhirinaki

Mā te hoahoa matatau, ngā wāhanga kounga teitei, me ngā paerewa hanga tino pakari, ka whakaratohia e ngā hua SPD a Mutai Electricte mahi pumau, te urupare tere, me te pono mō te wā roaAhakoa i roto i ngā taiao ahumahi, i ngā pūnaha pūngao hou rānei, ka āwhina ā mātou SPD ki te whakaritete mahi tonu me te haumaru o ngā taputapu.
