Te Mārama i ngā Tono Hiko o ngā Rohe Kāinga me ngā Whakamahinga Tapatoru LV
Te Whakaaetanga i ngā Tapatoru LV ki ngā Tau Utu Rerekē i ngā Huinga Kāinga
Ko ngā takiwā hokohoko e hiahiatia ana ngā punaha rerekētanga hiko nā te huringa o ngā herekore hiko i roto i ngā wāhi hoko, ngā taputapu whare, me ngā pokapoka raraunga. Me āwhina te taputapu hiko mōhio ki ngā tauwā e rerekē ana—mai i ngā mahi HVAC mā te wā, ki ngā taputapu hiahia teitei pāpaku pērā i ngā karaka. Ko ngā whakaritenga matua ko:
- Ngā hiko maataamua ki te hiko toharite : Ka huri ake ngā taputapu hokohoko ki te 40% ake ake i te ahiahi (Pukapuka Whakahaere Hiko 2023), ka hiahiatia ai te mātau kikoikoi kiko.
- Te whakarere i ngā āhuatanga harmonik : Ko te mārama anuanu hou me ngā taputapu IT e hāngai ana i ngā āhuatanga harmonik, e hiahiatia ana ngā kauwhiu e uru mai ana hei aukati i te kikokiko me te heke iho o ngā turupairehe.

Te whakatakotoranga : Ko ngā hoahoa āwhānui e taea ai te tāpiri i ngā ara i te wā e neke atu ana ngā kainoho, kāore he panonitanga o te punaha—e taea ai ngā whakapai ake takirua e hāngai ana ki ngā wāhi rīhi, ki te kāinga rānei.
Ko te whiriwhiri i ngā kapa iti ake e mōrearea ai te pakaru pakaru i te wā o ngā hiko maataamua, ā, ko ngā punaha nui ake e piki ake ai ngā utu tuatahi umanga ~15% ā, e heke ai i te mātauranga whakahaere.
Ngā Tōaitanga Maru me te Maru i ngā Rohe Whakamahinga Ķoretake me ngā Rohe Hoko Nui-Tono
Ko ngā whanaketanga ķoretake e hono ana i ngā kainga, hokohoko, me ngā tinihanga, e here ana i te taputapu maru mō ngā pūnaha 400V–690V me ngā kaha taraiwa e piki ake ana i te 6,300A. Ngā āhuatanga matua:
- Te Whakapumautanga Taura : Ka pāngia ngā rohe tiaki-tiaki ki te 8% iti iho o te maru i te wā pikinga, e here ana i ngā kaiwhakarāwekenga maru tūmatanui, i ngā kaiwhakarāwekenga haepapa ranei hei āki ai i te hapa.
- Te whakauru maru : Ko ngā maru poto-korikori e piki ake ana i te 50kA i ngā rohe pakihi matua e here ana i ngā tautuhinga totohu-mōhio tūmatanui me te whakauru tīpokaia kia taea te wehe i ngā hapa kaua ko ngā whakamutunga tū ake.
-
Te Mana Whakatikahanga Taiao : E hiahiatia ana ngā pouaka IP55 mō ngā tāpiritanga waho i ngā komati parkingi, i ngā rūma taonga runga rānei kia āki ai i te puehu, te waimā, me ngā kirihou kikohe i te taone.
Ko te tika o te rahi e aukati ana i ngā take parauri, e pā ana ki te 80% o ngā whara hiko i ngā whakapākanga hokohoko (NFPA 70E 2023).
Ngā Paerewa Matua Mō te Tīpoka LV: Maru, Maru, Tītoki IP, me te Kaha Kua Ora
Te Whakarāwekenga i te Tukutuku Umanga Iti mā te Whakamātau i te Taura Iaite me ng Tātaitanga Katoa o te Tīmata
Kia tika te rahi o te taputapu me te whakarite kia ōrite ngā tatauranga volta ki te mea e hiahiatia ana e te pūnaha tohutohu kia rere ai tika. Ka taea e te nuinga o ngā taputapu taura volta iti te kawe i te 1000 volts, engari ko ngā wāhi e āhua rerekē ana ngā volta e hiahiatia ana he aha atu hei titiro kia kaua ai te whakamātautau ki te takotoranga, kia kaua hoki ngā wāhanga e mate mōrearea. Heoi anoo, me titiro hoki ki ngā herekai o te irahiko. Ko ngā rohe tohutohu ka kitea he iti ake i te 30 ki te 50% te whakamahi i te hiko i te wā hangaga, i te wā e noho ai te katoa. Hei tauira, ko te tatau irahiko 4000 amp e tino hiahiatia ana kia taea ai te kawe i ngā waeine noa, tāraiwa hoki i ngā wā poto ka hāungaia ngā tīramarama, ngā kōpae ranei. Me taea hoki e te taputapu te ora mai i ngā ara poto e neke ake i te 100 kiloampere i ngā rohe tāone e pai ana ngā tāpoi. Me whakatutuki katoa i ngā tautohetohe e tohua ana i IEC 61439-1 e pā ana ki tana wera, tana uauatanga ki te pakaru hiko, me tana kaha tinana. Mā te tāpiri i te 15 ki te 20% atu anō ki ēnei tātaitanga ka taea ai te āki ki ngā panonitanga kāore i whakarārangihia, me te prepare mō ngā taputapu hou e tāpiri ana i muri ake nei.
Te Rāingi IP me te Arataki mō ngā Tāutanga Kaupapa-Āmiki, Āhuatanga Ārai
Ko te āhua e taea ai te whakahaere i ngā tikanga taiao rerekē e rua ngā mea matua: arataki aukati urunga (ngā tātaitanga IP e kōrero ana katoa), me ngā punaha e tipu ana i te wā. Ko ngā tātaitanga IP nei i te matua e whakaatu ana i te pēhea o te tapanga o ngā taputapu ki te paraihe, ki te wai hoki. Mea nui ake i te arataki IP20 mō ngā tautuhinga hiko mō roto, engari mēnā kei waho, kei raro, i te taha o te moana rānei, ka hiahiatia te IP54, te mea pai ake hoki kia aukatia ai ngā whiti wai, ngā hau paraumu, me ngā pārito iti katoa e noho ana. Ka huri katoa te hoahoa takitahi ina pā ana ki te whānuitanga o ngā wherewherenga. Engari i te whakaaro mō te whānuitanga i muri ake, ka taea e ngā kamupene te whakarite mō te tipu mai anō i te timatanga. Mā te whakauru i ngā wāhanga kua hangaia kē, ka taea e ngā kamupene te tāpiri anō i ngā tapowha hiko, i ngā taputapu ine rānei, tae atu anō ki ngā hangarau mōhio pūkaha, ā, e pērā anō hoki te huringa o ō rātou hiahia. Hei tauira i te ao tūmatanui: ko te whānuitanga o te kapara mā te 25% mā te whakamahi i ngā wāhanga takitahi e iti ana te wā kua pau, heoi anō te 70% i te nuinga o te wā i te wehenga i ngā papa tawhito. Tāpirihia atu ngā matērau e aukati ana i te putiputi, ngā punaha taraiwa e tūpato ana ahakoa te hurihanga o te wera, ā, ka taea e tēnei momo tautuhinga te ora ake i te 20 tau i te nuinga o te wareware e hua ana i ngā tikanga rerekē o te rangi, me ngā kirihou kei te hau.
Ngā Āhuatanga Matua Mōrearea me te Tiaki i ngā Taputapu Whakamātau Taura Iharaira mō te Whakamahi Pakari
Te Tiaki i te Anuanu me te Pānga Poto: Te Whakawhitinga Kotahi me te Whakauru I²t
Me whakaaro ngā taputapu whakamātau taura iharaira pai ki te whakarite kia taea e ngā taputapu tiaki te wehe i ngā pāga tika, kaua ko ngā ara tukutuku runga rānei, ina koa kia kaua e whai pāga ki ngā pūnaha matua pērā i ngā karaka, ngā paraihe ahi, me ngā kotahi hāngai hau hou. Kātatahi ngā paraihe arataki māmāri i te wātea o rātou I te taumata tāpiripiri e āwhina ana kia tino mōhiotia e ngā taputapu i raro i te ara tukutuku te nui o te wātea kia noho haumaru ai, kia tu ana te pāga ki te 200 kiloampere e ai ki te Puka Rangahau Mātauranga Plant. Ko te ara e mahi ai tēnei whakawhitinga kotahi he nuinga i ētahi take matua pērā i...
- Ngā āhuatanga tohua kōaro e matua whai whakaaro ana ki te wāhi o te pāga me te whakaiti i te roa o te wehenga
- Ngā hoahoa here-tau e pakari ana i te tau mātau tōpoki me te wātea pāga
- Ngā pātene tōirirotia e te rohe (ZSIs) mō ngā whatunga kārihi, e whakakaha ana i te wehenga iti ake i te tētahi hēkona i waenganui i ngā pātene matua me ngā pātene kaihoko
Haumātauranga me te Arataki mō te Tārua Maruaroa me ngā Tīmataka IEC 61439-1/2
Ko te taputapu hiko o nāianei e whakauru ana i te hanganga e here ana i te tārua, kua whakamatauria ki ngā tīmataka IEC 61439-1/2, e whakaiti ana i te kaha o te takirua i raro i te 8 cal/cm²—te rāwekenga mō ngā pānga tuarua—trū ahuatanga e toru e pā ana ki te hoahoa:
| Ahuatanga Whakaiti Tārua Maruaroa | Te mahi |
|---|---|
| Ngā ara whakamāmautanga toki | Whakarahia te kaha e puia ana ki runga, i waho i ngā kaimahi |
| Wehenga o roto | Wehia ngā tārua ki roto i ngā wā kua wehia, kua whakakaha |
| Te tārua mōhio mā te māmā | Tīkina ia 2 ms mā ngā rārangi kaiwhakarato kōpae e whakamātau ai i te tārua |
Ko te whai mātai he whakamātau anuanu—kāore i ngā waeine anake—o te kaha ā-tau, te eke atu ki te poka poto (≤65 kA/1 s), me ngā tepe e whakaae ana ki te whakapakari ake i ngā tikanga tāpoi katoa. Ina honoa ki ngā tikanga tiaki e ū ana ki NFPA 70E me ngā taputapu ārai e tika ana, ka nekehia ēnei āhuatanga i te 72% ngā pānga e hāngai ana ki te arca.
FAQ
-
He aha ngā whakaaro matua ina tīmata ana te kōwhiringa i te taputapu hiko LV mō ngā whare hokohoko?
Ko ngā whakaaro matua ko te āhua mōhio ki ngā tau e rerekē ana, te whakahaere i te tāpoi piki vs. tohumu, te whakaiti i ngā harimonikia, me te āhua mōhio kia taea ai te whānui ake mō ngā kainoho kāore he huringa anuanu i te pūnaha.
-
Pēhea te pānga o te tūpono o te volta ki ngā pūnaha hiko hokohoko?
I ngā rohe kīato, he mea matua nui te tūpono o te volta nā ngā tūmomo volta e taea ana i te wā o te tāpoi piki. E hiahiatia ana pea ngā kaiwhakarite volta aunoa, i ngā kaiwhakarite hiko whakarewa rāwekenga rānei kia tūpono ai.
-
He aha te tūwāhi o te hoahoa āhua mōhio i ngā taputapu hiko LV?
Ko te hoahoa takirua e āwhina ana i te whānuitanga ngāwari mā te tuinga i ngā wāhanga rite ki te mahi, he iti ake te wā kore mahi, ā, ka taea ngā tūhuratanga anamata e hāngai ana ki te hiahia.
-
He aha te take e nui ana te whakamarumaru urunga (IP) mō te taputapu tīkini LV?
Ko ngā tātaitanga IP e whakaatu ana i te āhua o te taputapu kia pakari ki ngā take taiao pērā i te puehu me te wai, kia pono ai, kia roa ai hoki te ora i ngā tikanga rerekē, īt especially mō ngā wāhi waho, i ngā wāhi uaua.
