Te Parenga Ngaru Whānui mō ngā Pūnaha Hiko Pono

I tēnei ao hiko e piki haere ana te hihiko, he mea nui te tiaki i ngā taputapu mai i ngā ngaru hiko nui e puta mai ana i te uira, i ngā mahi whakawhiti rānei. Nā MUTAINgā Pūrere Ārai Pupuhi (SPD), tae atu ki te Momo 1 me te Momo 2, kua hangaia hei tiaki i ō pūnaha hiko me te whakarite kia kore e haukotia te mahi puta noa i te whānuitanga o ngā taiao ngaohiko.

Momo 1 SPD – Parenga Taumaha mō ngā Pānga Uira Tika

MUTAI'sRaupapa T1Kua hangaia te SPD hei whakahaere i ngā ngaru hiko nui, inā koa mai i ngā pānga uira tika. I hangaia mō ngā taiao pakari pēnei i ngā papa ahumahi, ngā teihana hiko iti, me ngā pūnaha tohatoha hiko arumoni.

Ngā Kaupapa Matua Hangarau:

• Iahiko Tukunga Whakatauranga (8/20μs)Tae atu ki te 50kA

• Te Auaha Tukunga Mōrahi (8/20μs)Tae atu ki te 200kA

• Iahiko Ārai (10/350μs): 15kA ki te 50kA

• Taumata Tiaki Ngaohiko: ≤2.0kV / ≤3.0kV

• Wā Whakautu: ≤100ns

• Te pāmahana whakahaere-40℃ ki te +80℃

• Rauemi: Nairona ātete-mura

• Te Parenga WhakauruIP20

• Te kaha o te waea: 6–35mm²

He tino pai te mimiti pūngao, he tere te urupare, he teitei hoki te taumata tiaki me te tautoko whānui i ngā ngaohiko mahi (220/385V).

Momo 2 SPD – Parenga Tuarua mō ngā Taputapu Hiko

TeRaupapa T2Ka tukuna e te SPD te parenga ngaru o raro, he mea tino pai mō ngā taputapu hiko kāinga, arumoni, me ngā taputapu hiko tairongo. I hangaia mō ngā pānga uira ā-korekore me ngā ngaru whakawhiti.

Ngā Kaupapa Matua Hangarau:

• Iahiko Tukunga Paerewa (8/20μs): 5kA – 60kA

• Iahiko Tukunga MōrahiTae atu ki te 100kA

• Taumata Parenga Ngaohiko (Ki Runga)Tae noa ki te 1.5kV

• Awhe Ngaohiko Mahi: 275V–440V

• Au Puta: <20µA

• Wā Whakautu: <25ns

Mā tēnei raupapa ka tiakina pai ngā pūnaha ngaohiko-iti mā te pupuri i ngā ngaru ngaohiko i mua i te taenga ki ngā kawenga tairongo.

Ngā Whakaritenga Tāutanga

• Te WhakamaungaReriwe DIN paerewa 35mm

• HonongaWaea parahi kounga teitei, te roa hononga katoa <0.5m

• Awhe WaeaWaea ngohengohe 2.5–16mm² / Waea mārō 2.5–25mm²

• Te Whakaritenga TiakiMe mahi tahi me ngā kaiwawao ara iahiko iti, me ngā fiusi rānei

• Hononga Whenua: Te horahanga o te waea whenua ≥4mm²

He mea nui te tāutanga tika me te whenua kia pai ai te mahi tiaki.
