Mīhini Unipolar: taputapu, ngā āhuatanga hangarau me te āhuatanga o te hononga

Circuit kaiwahi - he pūrere whakawhitinga, te conductive nāianei hiko tīkina me tahuri atu te mana i roto i te taikaha o te uara mata. Kei te whakamahia te reira mo te tiaki ki kikī iahiko. Single-pou aunoa tiaki kotahi anake waea.

Te pūrere me te parau tumu o te mahi

Ko te āhuatanga matua o te whakakā he iti, me te whakaweto tere. mīhini Unipolar mahi i roto i rua tikanga: he kōwae haerenga waiariki, me te hiko. Ko te tuatahi mono te ara iahiko i roto i te hui o te nui haere kawenga o te mahi mo te wa roa, me te tuarua - tonu, ka he-taiawhio poto.

pūrere tiaki Thermal ko te paraharaha bimetal. A, no te haere o nāianei i roto i taua mea ki runga ake i te mōrahi, reira āta pupū ake me whakaiti, e aki ana i te hua, te mīhini kati-atu. I muri te meangiti pereti hoki ki wahi, a ka he rite ano hoki te mahi te pana. Hei tomo ki te mahi, te hono ā-ringa i te reira.

ngā o te pōkai kei roto i te matua te pūrere hiko. A, no te haere i roto i te nāianei poto-iahiko puta awhiowhio te hiko mandrel mara tuku, e mono i te mīhini. Ai e whakatuwheratia nga hoapā mana, iahiko itoito de-. Ka haere ratou ra te nāianei nui, he pewa. taka ki roto ki te ruma pewa, te wahi i nga pereti konganuku whakarara. Ki te to ratou awhina, e wawahi te pewa me saietí ake.

whakamahi hoki i te mīhini rite te whakakā i tītaka te hua mana ā-.

Ko te whakamahi o te mania takahi kotahi-pou

Waea i roto i te fare ka tuwhaina e ki te maha ngā rōpū. Hono i te mīhini kotahi-pou hua te i roto i te wahi pakaru o te kaiwhakahaere wāhanga. Kei te whakanohoia te reira i runga i te tereina din, a whakaurua i roto i tona waea Jig mana runga te. Kei te hono waea paruruhia ki te rawhi raro. Ki te aki nga waea i te tīwiri, me kia tightened ratou ki tautooraa iti.

Tikanga, kua hono te terminals o runga o te mihini kotahi-pou ki te supply mana i roto i te heru, me i te waea o raro mahi i roto i ngā rōpū. Ka taea e koe te whakaturia pūrere tārua maha.

tohu

tuatea iahiko i te tapanga paerewa, e lau nei i runga ki raro.

runanga Uara i runga i te mea Housing ona tawhā taketake:

• waitohu - EKF;
• tau rangatū - VA47-29;
• āhuatanga "C" me te nāianei tauanga ki te aunoa kotahi-pou - 25A;
• ngaohiko supply tauanga - 230/415 V;
• tīkina mōrahi ngā ara iahiko atu poto i - 4500 A;
• 3 - piha rohe o nāianei.

Na roto i te waitohu, ka taea e koe te tautuhi i te kaiwhakanao. Mihini he mea tika ki te whiriwhiri i rama pai-mohiotia: Legrand, ABB, iek, EKF, me ētahi atu.

Tapanga i runga i te mīhini 230/415 B tikanga e taea te pūrere mahi i roto i te kotahi-wāhanga, me whatunga toru-wāhanga. Te nuinga o nga waka i roto i te waea whare i tenei āheinga.

Whakatauria nāianei - ko te uara o te nāianei i nei e kore te mīhini e mahi mo te wa roa. A, no te te nui haere te reira i te 13%, ka tahuri te reira atu i muri i te haora. Ko te nui te uara o te nāianei roa-rere, te tere te mahi. Ko te whakaaro matua o te mīhini - ki te ārai i pukā o te waea, ka tūhono i te kawenga. He mea nui kia te nāianei kaiwhakahaere tīkina he nui mīhini haapa'oraa, e kore e hurihia.

Time-nāianei āhuatanga o "C" tikanga e te triggering atu o tikanga e rua puta i muri i whakanui i fivefold te nāianei tauanga. Ko reira e tika ana mō te māramatanga me te nuinga o taputapu. Ki te he utu te tomokanga ki tenei āhuatanga i te mīhini, kia tāuta reira i runga i te mīhini ki te āhuatanga matua o te tāuru "B" i roto i te rōpū flat. te tikanga o tēnei e mo te era atu katoa te taua āhuatanga e mahi i te reira tere. Na e kore koe e whai ki te rere ki te tomokanga, ka whakauru aunoa reira. pūrere tīpakonga tika ki te āhuatanga e tika ana whakarato selectivity hiahiatia o hīrau.

whakaatu mōrahi nāianei hīrau whakaaetia tona uara mōrahi i ai taea ki te tutakina iho i te iti rawa kotahi te mīhini, ko te.

Tau o amo

Ki te whiriwhiri koe i te kotahi-pou mīhini rua-pou ranei, he mea nui ki te, te wahi ki te tāuta i te reira. I tomo te fare te rōpū matua kia tāuta bipole. Tenei ka tukua reliably momotu te waea i te kāinga i roto i hanga ka ki te tahuri atu te wāhanga ki kūpapa. A, no te te waea 2 taea te eke mīhini ki te pou kotahi whakaurua ki te whare. I roto i te aroaro o te kaiwhakahaere uhupoho hoatu mīhini pourua whakamöhio.

I runga i ia peka o te whatunga kāinga hono te mīhini kotahi-pou ki te RCD.

Ki te Powered te fare e te ara iahiko e toru-wāhanga kia tāuta i te tāuru matua mīhini wha-pou.

Aunoa-pou kotahi: utu

Single-pou aunoa iti i roto i ētahi atu i roto i te lineup ki te maha nui o amo. Ka taea te hokona hua kāinga mō te 40-50 moni., ka ko kua rama kawemai 150-200 moni. He mea nui ki te whiriwhiri i te whakaaro i runga i te hononga kounga-utu, nui atu i te hunga e te hunga iti.

Mistakes i roto i te kōwhiri i te mīhini

Te kōwhiri i taka, tukua kaiwhakamahi he maha o ngā hapa.

1. Ma te arata'ihia e te katoa kohi mana hei utu o waea ki te tiaki ki kikī. Tāuta i te mīhini kaha i runga i te waea ngoikore arata'i ki tona pukā. He mea nui ki te tiki ake i te pūrere ki runga ki te wāhanga ripeka o te waea.
2. E mea pinepine whakaturia te taua mihini i runga i ngā rārangi katoa, i te mea he aha e etahi o ratou overloaded. Hoki Me turanga ki te kia tiakina i te 25 A, me mo te rama - 16 A. te raina ārahi ki te karati, e taea e puhoi utaina ki taputapu mana kaha. Tenei he mea tika ki te tāuta i te mīhini i 32 A.
3. Kaua e whiriwhiri mihini mo te utu. He pai ki te hoko hua o rama rongonui, te wahi whai te kounga e.

mutunga

Hei tīpako tika te mīhini kotahi-pou me mahino te waehere ki runga ki te whare i te taha ki mua. E tīpakohia āhuatanga pūrere i runga i te momo o hono kawenga me te waea ripeka wāhanga rānei.
