E toru-pou iahiko takahi: he tirohanga whānui, momo, āhuatanga me te arotake

E hangaia tuatea iahiko ki te aruaru i te whatunga hiko ka nui rawa te iahiko nāianei, me te poto whakahaere. tiaki ratou i te waea me te hono ki reira e kiritaki panamaha me roto i tetahi ki te wha amo. hangaia E toru-pou iahiko kaiwahi i ki te tiaki i te ara iahiko e toru-wāhanga i te wa ano ranei te waea e toru-wāhanga. Ki te kotahi o nga rārangi o te aituā, e monokia tonu toru amo.

Ko te pūrere solves te mahi e whai ake nei:

• wāhanga whatunga tiaki;
• rärangi ārai wahi iahiko;
• te kōwhiringa tika o te ārai o ngā haerenga kāore.

āhuatanga o

Ko te āhuatanga matua o te mīhini - ngā whakatau reira kaha e pakaru, me te tere tapahia-atu. mahi ratou i tikanga whakaweto rua: waiariki, me te hiko. Ko te tuatahi oroko te ara iahiko, ka he taiawhio poto, me te tuarua - te mahi o te nāianei tonu rawa te lau peé. Ka taea te whakamahi Pū rite te whakakā mā te kī mana.

Whakatauria kaha whawhati

uara āhuatanga tohu i te mōrahi whakaaetia nāianei poto-iahiko i ai taea ki te momotu i te waea ki ngā pūrere hono tukunga i te iti rawa kotahi te pana he. Kei te tohua te reira i runga i te whare o te mīhini, me te kua he uara o:

• 4,5 KA - ki te tiaki ki poto rārangi mara taiawhio o te taonga tūmataiti, te wahi e kore e ki te kawenga raina ātete i te substation nui ake i te 0.05 ohms;
• 6 KA - tiaki te rängai noho me nga wahi tūmatanui, kei hea he kore i raro i te 0.04 ohms te resistance aho;
• 10 KA - whakamahia ki te ārai kino ki te rārangi mana huri noa te substation.

whakarerekētanga taunakitia tauira 6 KA mō iahiko kāinga.

āhuatanga Wā-nāianei

A, no te kohi mana pāhiwihiwi meinga e kawenga rerekētanga, me te faatupu whakihauā ranei pūrere iahiko, i reira kia kia pai teka whakaaro tiaki e tika ana ki rawa te nāianei tauanga. Ki te whakaiti i te tūponotanga o triggering mīhini whakamahia ki këtia āhuatanga wā-nāianei (BTX). Tawhā tohu te wa cutoff i te tetahi ōwehenga o nāianei ki te uara mata. Kei te whai ake BTX.

1. B - te wae haerenga hiko haerenga i muri i 0,015 hēkona i takitoru e hua i roto i tēnei wā ki te whakapai kanohi ki te uara mata.
2. C - te āhuatanga tino noa, ka rongo tiaki e te whakanui ake i te uara mata 5 wā. He pai mō te rama, me te taputapu ki ngā inrush āhua Machines.
3. D - mihini hangaia mō te nui ngā inrush, pērā i ka te kōhua hiko, motors hiko, me te tahi atu pūrere toru-wāhanga. Te nuinga whakamahia i roto i te ahumahi.

tuatea Overview

hono Machine te i waenganui i te pūtake te mana, me te waea, e me e tiakina. E toru-pou iahiko kaiwahi Kei toru takirua whakapā, te wahi hono ia te i roto i te raupapa ki te wae haerenga waiariki, me te hiko. mono wāhanga aunoa anake kahore whawhati te kūpapa, e kore e nei hono ki reira. Ki te hiahia koe ki te momotu i te waea kūpapa, whakamahia tauira wha-pou. Tikanga, kei te whakamahia e ratou i runga i te tāuru matua.

Ko te whaitua me kāinga tūmataiti whakamahia mihini o te piha haapiiraa no te kawenga āhua. whiriwhiri te kaha o nāianei kei te rite ki te kaha o nga whakaaro tūhono, kei hea he rua te paepae te hāhi ki te whakakore pai teka.

hua Tūaritia iek umanga, o EKF, dek, INTES me "contactor". hua Domestic i rawaka tika me utu whaitake. Whānui e atu te utu mihini whakamahia i roto i te 16 A me 25 Imports A., engari kei te whakaputa kamupene pai-mohiotia kounga teitei me te tauira pono. I runga i te whakakā aunoa utu e toru-pou i kamupene pai-mohiotia ai kia tino rerekē, engari he reira kounga ōrite.

tono pūrere tiaki ki toru-wāhanga o nāianei i te whai wāhi o te whare, me te mo taputapu mana ngaio ki te ngaohiko o 380 V, mo te tauira, he toru-pou 100a pana aunoa.

kia hāngai ana tēnei kaha ki te counter, ki te tu i te reira i muri i te pana. Ko te tikanga e kore e he reira nui atu i 63 A. whakamahia te toru-pou iahiko kaiwahi atu kaha i roto i te ahumahi.

Mai i te urupare me te tohutohu o electricians mātanga whai reira e kore e taea te whakamahi mihini ki faaroo piriponotanga i roto i tetahi take. Ko te mōrea o te ahi kore ranei o te mea tenei.

tukua te wha-waea e toru-wāhanga, me te kore e ki te kāinga mahi. Kei te uaua ratou whakamahia taputapu tauanga i 380 V. te wāhanga i roto i te rōpū tohatoha e wehea. hua tenei 3 aho motuhake ki te ngaohiko o 220 V.

Ko te painga o mihini maha-pou ko te kaha ki te wā kotahi whakahaere rārangi maha. Na roto i te tāuta i te pana 25A e toru-wae hāngai mana te mana e toru-pou aunoa taea te kawea i roto i runga i ia raina takitahi. I roto i te hui o te taiawhio poto i runga i tetahi o ratou tutakina atu katoa i kotahi. Tikanga, i runga i ia raina ki te tāuta atu tuatea taiawhio kotahi-wāhanga. A, no te kore tetahi o ratou wāhanga mahi, e faarahi tika pūnaha.

mihini BA raupapa

hua mīhini kāinga raupapa AE me te BA. He tawhitotia te momo tuatahi, a ka te uaua whakamahia reira. He kaha iti o te tinana, te kore o te hononga ki te din-tereina. Hoki ngā tono kāinga he raupapa hua pai hāngai VA tātai mō ngā ake ki 63 A, B āhuatanga, C, D, me te kaha pakaru o 4.5 KA.

Domestic toru-pou tuatea iahiko VA tutuki tino whakaritenga hou, i te te haapa'oraa i te utu tino raro atu i ngā tauira kawemai.

E ai ki te maha arotake, tauira kawemai whai ki te kia tino tika i taua utu tiketike. Ko e paku ratou, ahakoa iti tauira kāinga.

mutunga

E toru-pou iahiko kaiwahi ko te wahi nui o te pūnaha hiko o te kāinga. Te kōwhiri i ngā tauira utu, kia whanau ai i roto i te ngakau e kia te toenga o te taputapu o te taumata kotahi: waea, whakakā me turanga, pouaka komititanga, huaki rama.

kei reira tonu nga āhuatanga matua o mihini i te taha ki mua o te whare. E tīpakohia ratou i runga i te rahi waea me te nui o te kawenga hono.
