Nāianei pārōnaki. mīhini pārōnaki: āhuatanga, whakaaro

Hoki māramatanga māmā o te nāianei pārōnaki kia whakaaro te tukanga tinana. A, no te reira te mea he pa o te ara tataki kiriweti, he aha e kore ru hiko? He kitea te whakahoki: wehe ārai rere o nāianei i roto i te tinana tangata. Otiia ki te whanau kaiwhakahaere, kamata i runga i te tïpako tuuraa me pa ki te waea? Ko te taua te pānga - kahore he ru hiko. E kore e te tïpako maukati ara iahiko i roto i te tinana ki te whenua.

Ko te ariā o te nāianei pārōnaki

I roto i te āhua i reira he he tukanga tinana pērā i pārōnaki nāianei. Tenei ariā Ko te rahinga pere, faaite rite te moni o te ngā reira i roto i te ara iahiko, tangohia i roto i te tikanga o te tapawhā toharite. Ki puta pārōnaki o nāianei, ki te tukanga tinana puta, o nāianei leakage huaina. Ko he tika ki te kua i haapa'o ki kotahi huru reira: te whare taputapu, te wahi i he nāianei leakage reira ki te kia hono ki te whenua. Kore, ki te kore e niuhia te tinana, na te takanga o te leakage nāianei e kore e meinga te nāianei pārōnaki. Na wäriu takahi taiawhio nāianei (RCD) e kore e mahi.

Kōrero i waenganui i te pārōnaki me te nāianei leakage

A, no te puta te leakage nāianei i roto i te ara iahiko, puta reira ki nga mea timatanga he te rauemi conductive (kuhunga whakarewa mo taputapu, paipa whakawera, me ētahi atu) i te wahi i raro i ngaohiko (ara iahiko, waea). I roto i enei pae poto-leakage kore e whai. Na pera i reira he kahore meka o te maumaui mahi iahiko (kitea lesion reira).

Mai te nāianei pārōnaki, ka pāngarau tohu tona faaite te rerekētanga (uara pere) i waenganui i te nāianei i te nāianei pūtake putanga me i muri i te kawenga, ko reira mahinongofua e ko te reira tata ōrite ki te nāianei leakage. Otiia ki te tino vai te whakamutunga i roto i te ofatiraa, pērā i mātao, te taiao haumākū nui, i roto i nei e taea e ia whiti, ranei te tahi mea atu, puta te nāianei pārōnaki, ka te hononga ki te whenua.

Hīrau me hīrau-kore ngā pārōnaki

I raro i hīrau nāianei (ranei hīrau) ite te rere pārōnaki o nāianei i ngā i roto i te turuturu momotunga VDT i te mekameka.

Ko te rere o nāianei i te mea whakaaetia i roto i te ara iahiko pūrere (RCD) ka huaina tona actuation e kore e puta te pārōnaki nāianei kore-hīrau.

Ko te ara iahiko utaina mahi pūrere pini-momo: rectifiers, motuhake whakaaro mamati mō te mana te mana - taputapu hou katoa, ko te aroaro o ngā papamuri pārōnaki. Otiia e kore e he ngā kino enei ngā, a kore e taea te momotu i te ara iahiko hiko i roto i tenei take. Na reira, tīpakohia te RCD hīrau paepae te pērā i kore ki te tauhohe ki te uara whakahaere o te papamuri, ka tahuri atu rawa tenei uara te nāianei leakage.

RCD Mīhini pārōnaki ranei

I roto i te tikanga ki te tiaki i te ara iahiko ki ngā tetahi he whenua rahinga nui, whakawhanakehia motuhake kupu taka iahiko. tonu whakamatautau peia pūrere te ara iahiko whakahaeretia hoki te leakage hiko. Kia ka waiho te moni pere o nga uara ngā raina nui ake i te kore me te tomo i te rohe rapunga, ia tonu tutakina atu te ara iahiko. E whakatakotoria taua pūnaha me i kotahi-wāhanga, me te toru-wā rārangi.

Āhuatanga whakakā pārōnaki

rerekē Various akatuke'anga whakaaro tiaki i ia atu e:

• āhuatanga hoahoa;
• tikanga leakage o hiko;
• tautuhinga tūtohutanga;
• tere.

Tei runga i te hoahoa āhuatanga e:

• pūrere VDT (pana pārōnaki), ai te mea kahore he tiaki ki ngā tiketike. huru ratou ki Tuhinga ngā, engari ki te tiaki i to ratou kaupapa, Me ngā wā katoa ki te ngā fuses.
• RCBOs taputapu i reira whakaratohia hoki momo aunoa pana. He whakaaro ao ki te mahi rua enei - ki te tiaki ki taiawhio poto me te kikī, me te mana leakage.
• pūrere BDT ki mīhini tiki taea i te wāhi hononga. tikanga te pūrere te ki kia tāuta tahi ki te kaiwahi i ara iahiko. mahi Ko tōna hoahoa kei roto i te ara taua e anake taea te hononga kotahi-wā ki te mīhini.

Tei runga i te āhua o te ngā leakage te whakarite i ngā pūrere rōpū paruru e whai ake nei whakarerekētanga:

• AC - pūrere mahi ki tauutuutu nāianei sinusoidal. e kore ratou e whakautu ki te pārōnaki ngā pini e puta i te kau, ka, mo te tauira, kōrekoreko, rama X-ray taputapu, pūrere hoki tukatuka tohu mōhiohio, pūtahuri thyristor.
• A - whakatangi mō te tiaki i te pumanawa tonu, me te tauutuutu nāianei. Kaua e mohio ki te tihi pini ngā pārōnaki leakage. mahi ratou i roto i iahiko hiko pērā i rectifiers, positionally tauwehe faafariuraa. Aukatia te leakage whenua hiko pākau i, e kua he wāhanga ngaohiko tamau.
• B - pūnaha mahi ki tāupe, o nāianei leakage tamau me te pumanawa.

Tūtohutanga pārōnaki whakakā kua te momo e whai ake nei:

• pūnaha tūtohutanga iti e mono iahiko whakapā autaki.
• Systems ki tiketike-raupapa tūtohutanga. Tiaki, ki te mea kua whakapā tika ki te kaiwhakahaere.
• Ahi-whawhai mahi.

E ai ki te wa e hiahiatia ana mō te mahi pūrere:

• mahi Inamata.
• Tere High.
• Hoki whakaaro whānui.
• Roa - momo whiriwhiri.

tiaki pārōnaki o nāianei o te whakaaro kaikōwhiri taea mono i te wahi anake o te taputapu, te wahi i puta te hara.

Nahea te wäriu takahi ara iahiko o nāianei

RCD titoa o te matua i roto i te puka o te whakakai me rua coils. Ko rite enei kopiko te taua, i hanga e te o tetahi waea wāhanga ripeka me te maha o hohoko ōrite. I muri i tetahi rerenga o nāianei pōkai i roto i te ahunga tāuru kawenga, a atu i roto i nga hoki kawenga ki te tuarua awhiowhio te. Mai haere ia kawenga te nāianei tauanga, ka whakarapopototia nga ngā i te wāhi me te i te putanga o Kirgofu kia kia rite. Ka rite ki te hua, te ngā i roto i te kopiko hanga te rere autō taua whakahaua i roto i te huarahi i te ritenga. Paraire ēnei rerenga tahi i te tahi, me te noho tonu te pūnaha i roto i te āhua kotahi. Ki te noa i reira ko tetahi o nāianei leakage, ka kia rerekē te papa autō, ka mahi i te pārōnaki tānga o nāianei, e ka hua i roto i te kuwaha o te hoapā hiko. Ko te raina hiko ka kia tino de-faaitoitohia.

Hea haumaru hāngai wäriu pūrere nāianei

I roto i te hanga hou me te wāhi taputapu hiko, me te te TEETH o atu whakamahi pūrere e nāianei wäriu. Kei te e te hua i roto i te haumaru whakahaere o whatunga hiko, me te he hekenga i roto i whara tenei whakatikaia. E whakamahia RCDs i roto i:

• whare tūmatanui: kura, whare ahurea, ngā hōhipera, hotels, whakaurunga hākinakina;
• whare me te takitahi fare noho: whare, whare, rātau, whare turuki;
• wāhi hokohoko, rawa hanga i runga i te pūtake o ngā hanganga whakarewa;
• whare mō ngā take whakahaere;
• hinonga ahumahi.

kōwhiringa Hononga kaupapa RCD

Pārōnaki pūrere paruru o nāianei ki te whakaputa i te maha rerekē o ngā wāhanga aroturuki. He kotahi-wā,-wāhanga e rua, me te toru-wāhanga wäriu tuatea iahiko o nāianei.

Ki te he wāhanga kotahi te aho, me te me kia hono ki reira, me te RCD takahi ara iahiko kotahi, kahore tahi he tikanga i roto i te parau tumu, te mea ki te hoatu i roto i te wahi tuatahi. E whakanohoia enei whakaaro katoa i runga i te tāuru ara iahiko. Noa watea atu ki te hoatu i runga i te wāhanga aunoa tuatahi, me te wäriu takahi taiawhio nāianei i muri. Mai te reira hono te kawenga ki e rua hoapā RCD hei utu o te wāhanga - i roto i te mīhini, hei utu o te kore - i roto i te pūrere tiaki.

Ki te te wehea te raina matua ki te maha rārangi ki pikaunga, te RCD hoatu mua, a ka hoki ia aho o te kaiwahi i taiawhio. He mea nui kia te tauanga o nāianei e taea whiti te RCD, ko roa nāianei whakahaere mīhini, te kore e kore e taea e ki te tiaki i te pūrere iho.

mutunga

mahi katoa i runga i te whakahaere o ngā pūnaha tiaki waea hiko, me te ara iahiko e pai mahue ki te hiko ngaio! koe anake e taea kohikohi ki o ratou ringa ohie ara iahiko, me te tūhono whakaaro haumaru, tino whai i nga tohutohu. Tikanga, He he tapanga hāngai ia whakapā.
