Momotuhi roto i Electrics L me N: momo o waea, ratou āhuatanga

kaiwhakanao ao o taputapu whare i roto i te whakaminenga o te taputapu e whakamahia ana tāutanga waea tae-ā. Ko te ti'araa i roto i te L hiko, me te N. Nā ki te tae tino tautuhia, kia hohoro te whakatau i te ruānuku e o te conductors he wā, kore ranei whenua. He nui tenei ina hono koe momotu te taputapu i te supply te mana ranei.

momo o taura

A, no te hono koe i ngā taputapu hiko, e kore e taea te mahi i te tāutanga o ngā pūnaha, kahore conductors motuhake. E hanga ana ratou o konumohe parahi ranei. whakahaere ēnei rauemi hiko tino pai.

Nui! Me hono waea konumohe ki konumohe anake. He mātātoa matū ratou. Ki te hono ratou ki te parahi, ka hohoro whakangaro i te ara iahiko whakawhiti nāianei. E hono nuinga o waea konumohe ki te nati me raka. Parahi - i roto i terminals. He mea utu te tuhituhi e te momo o te kaiwhakahaere muri he drawback nui - Kei te tere oxidized reira ki runga ki te rongo ki te rangi.

Poari i roto i te take i te wahi o te takanga o te hāora nāianei mutu ki te haere: ki te whakahokia mai te supply o te hiko, me te taratahi te waea i awenga waho mā te whakamahi i te rīpene hiko.

waea whakarōpū

Ko te kaiwhakahaere te tikanga kotahi uninsulated ranei tetahi ranei conductors atu kiriweti. Ko te momo tuarua o conductors pani ki te anga motuhake kore-konganuku. kia waiho hei rīpene tuuraa i awhiowhio te fi 'o te rauemi kaiota ranei tenei. e kore e waea whanau i tetahi coatings tiaki. E whakamahia ratou i roto i te hanga o ngā rārangi mana.

I runga i te i mua, faaoti tatou e te waea he:

• tiaki;
• wateatanga;
• mana;
• whakapuru.

kia whakamahia ratou rite rite whakaritea. Te ine iti i te whakaritenga mahi arata'i ki naianei o te supply mana. Ka rite ki te hua, ahi iahiko puta.

wāhanga ti'araa, kore me waea whenua

A, no te te ekeeke o whatunga hiko whakaaro whakamahi kāinga, me te ahumahi kiriweti taura. ngā ratou o te maha o conductors. pania Ia o ratou i roto i te tae e tika ana. Ti'araa LO, L, N i hiko whakaiti te wa o te tāutanga, me te mea e mahi hanga e tika ana.

Whakaahuatia i raro i roto i te hiko ti'araa L me N tino tutuki nga whakaritenga GOST 50462 me te whakamahia i roto i ngā utanga hiko i roto i nei te ngaohiko tae 1000 V. te ratou i earthed kūpapa. Tenei rōpū ngā te taputapu hiko katoa o noho, whare tari, ngā rauhanga arumoni. He aha te tae Tapa wāhanga L, kore, me kitea N me te whenua, ka tāuta whatunga hiko? Tatou i te reira.

nga conductors wāhanga

He conductors e kua faaitoitohia te AC. E huaina ratou nga conductors wāhanga. Iritihia i Ingarihi, i te "wā" wā tikanga he "aho", "waea kaha" "waea ora" ranei.

Mo te tangata i te tahanga kau i te mātao wāhanga kaiwhakahaere taea hua i roto i weranga taumaha ranei ara te mate. Eaha te auraa ki te Ihowa ti'araa hiko me N? Electrical waea wāhanga schematic tohua te Latin reta «L», a i roto i te maha-matua taura mātao o te kaiwhakahaere wāhanga peita i roto i tetahi o nga tae e whai ake nei:

• ma;
• mangu;
• parauri;
• whero.

Ngā Tūtohutanga! Ki te hoki tetahi take ruarua te hiko te iri o te mōhiohio e whakaatu waea taura tae-ā ki te whakatau i raro i te hiahia waea ngaohiko ki te whakamahi i iti-ngaohiko tohu ngaohiko.

kore Kaiārahi

E wehea ēnei waea hiko ki e toru ngā kāwai:

• pēne kūpapa.
• kore paruru (whenua) conductors.
• kaiwhakahaere kūpapa, te whakakotahi i te mahi tiaki me te mahi.

He aha te mea te ti'araa o hiko waea L me N? whatunga kūpapa kaiwhakahaere kūpapa ranei iahiko i roto i mekameka hiko rawea, Latin reta «N». Kore taura te whakahiko i te tae e whai ake nei:

• tae puru i runga i te roa katoa, kahore tetahi inclusions;
• tae puru i runga i te roa katoa o nga uaua, kahore inclusions atu.

Eaha te auraa Ihowa, N me te PE i roto i engineering hiko? PE (N-RE) - te kaiwhakahaere paruru, i te mea te roa katoa o te waea ngā i roto i te rārangi taura e peitatia ki tauutuutu kōwhai me te matomato.

Ko te kāwai tuatoru o te kore conductors (tamariki-waea), e te whakakotahi te mahi me ngā mahi tiaki, kua he momotuhi tae hiko (L me N). E tae puru, me nga pito o te hononga ki te whiu kōwhai-matomato.

Ko te hiahia ki te manatoko i te tohu

Ti'araa LO, L, N i te whakapuru whatunga hiko hiko - he taipitopito nui. Me pēhea te ki te tirohia i te tika o te waehere tae? Ki te mahi i tenei, e hiahia ana koe ki te whakamahi i te huriwiri tohu.

Hei whakatau i o nga conductors ko te wāhanga me te kore ki te awhina o te tohu huriwiri, e hiahia ana koe ki te pa ki reira ki tafe whanau wahi o waea. Ki te tiaho atu ana te arahina, ka reira ko whakapā ki te kaiwhakahaere wā. I muri mo te huriwiri ki te kaiwhakahaere kūpapa o te pānga luminous kore e waiho.

Ko te faufaa o te conductors tae-ā me pipiki tino ki nga ture o tona whakamahi tino e whakaiti i te wa o te rapu tāutanga me hape hiko, i te tau'a ore i teie mau titauraa tumu arata'i ki te tūpono ki te hauora.
