Oumu arataki: te parau tumu, me te whānui

whakarewa hongia e arataki whakawera kua tipu i runga i rau o nga tau, tonu reira ki whanake ki tenei ra. ka anga te reira i katoa ki te kitea o te kaiputaiao Michael Faraday tītohunga o whakaurutanga hiko. Kua i taua wa i hanga ai te nganatanga mahi tuatahi ki te hanga i tētahi hangarau whakarewa tango, hou, engari mutu ratou katoa i roto i te kore i roto i ngā āhuatanga taiwhanga. I te wa i reira i kore whakaurunga ahei o te whakaputa ngā mana rawaka nui haere auau.

I whakaarohia e te oumu arataki tuatahi e S. Farrant i roto i 1887. Otiia i mua i tona whakatinanatanga ka mau te reira i te rota o te wā. I roto i 1890, i te kamupene Benedicks Bultfabrik ite tenei whakaaro, i reira te mea he taea tūturu o te tauine ahumahi ki te ngohe konganuku mō te hangarau hou. Otiia i te wa i reira ko kahore he puna o nāianei kaha, na mahi te oumu whakauru, ki te moni iti o te whakarewa.

timata mea ki te huri i roto i te tīmatanga o te rau tau 20, ka kua pehia te hanganga oumu huringa nui. He generators kaha, me ngā puna mana o te auau tiketike, i whakamahia nei mo tona mahi.

Ko te whanaketanga o ngā pūrere Semiconductor me te putanga o te tuatahi pūtahuri thyristor tukua ki te waihanga pūnaha supply whai hua e hāngai ana ki runga ki a ratou. oumu arataki Modern ki te mahi ki nui o whakarewa. Na roto i te whakamahi o ngā pūnaha whakahaere auaha, kua riro te reira atu economical.

Tenei tikanga taea ki te whiwhi alloys parakore rawa o ngā konganuku. Ki te te tikanga rewa tuku iho, mo te tauira, i roto i te pūtahuri, tonu reira he ōrau nui o poke, ka whakamahi i tenei tikanga e ngaro. Tenei ka taea te hanga o alloys parakore rawa ki pai ana te whakahaere.

Mea faahiahia te parau tumu o te mahi o te oumu arataki ngā te whakawera i te whakarewa i roto i te whakapā mā te mara hiko. puta tenei mā te pūpoapoa, me e te kaimahi rite te kawenga ki te whakarewa oumu. Ki te he tiketike nui te kaha o te oumu, rewa reira.

oumu arataki iho taea whai i te whānuitanga o ngā āhuatanga, me te whakaaro. Ka taea te whakamahi i te reira i roto i te taputapu taiwhanga complexes nui ahumahi ranei, i te mana rerekē me te mahi.

Ka taea e Iti oumu arataki kāinga kia tino whai hua i roto i te taiwhanga kāinga. Ka taea te whakamahi i te reira ki te whakaputa i, mo te tauira, tūhoto ki tirotiro rerekē o te konutea me te tine, me te nui atu. A, no te mea e tika ana ki te whakaaro i te hanga o te parau tumu i runga ake. Whakamahia te generator nui-auau (i waenganui i te 30 MHz me runga ake), he puna mana kaha, kōwae mana, hua i roto i te para (e ai ngā o 6-15 tahuri o waea NDV 8.0) e taea e te wahi o te konutea ngohe i roto i te wa poto (15 -20 hēkona).

Kei te neke te whanaketanga o tenei hangarau ki te āta hanga-ake o ngā tipu kaha, te whakapai ake turanga mana pūtau, ake i te auau o te generator me te whakamahi o te auaha i roto i iahiko mana, mana, me te tiaki.
