Pehea e ho'olālā ai i ka mana o ka mea hana?

E ka kamailio e pili ana pehea e ho omaulia i ka mana hokii. No ka hana'ana i nā ho'ohelu,'ike'ia ka'ike ha'aha'a mai ka papa kula o electrodynamics, e pili pū me ka volter, current, power.

Nā palena no nā helu

No ka ho'ohālikelike i ka mea'ai i kēia manawa, pono'oe e'ike i kona ikaika, a me ka volta o ka puna. Mana (P) he pōpilikia ma ka hoonuiʻikena ma anakahi uila.

'O ke kumu no ka helu'ana

No ka ho'omaopopo'ana i ke'ano o ka helu'ana i ka lawe'ana o ka mea hana ahi, e ho'omau i ka ho'ohālikelike o kēlā me kēia mea nui i ho'ohana'ia i loko o ke kumuhana.

AC mana ua kapaʻia ka nui o ka uila kauoha e hele ma ka hāʻawi 'āpana o ke alakaʻi mele no pa alima manawa.

Anakahi uila - keia physical nui, a ua wehewehe aku ma ka uila kahua hana ma kaʻikena.

'O ka pūnaewele o ka mana'o W,'o ia ka huahana o 1A a 1V.

Nā'ano o ka helu'ana

Eia kekahi la'ana, hiki iā'oe ke helu i ka mana o ke kukui i kahi e holo nei i ka'ōpuni o 3 A, voltage 100 V.'O ka mana i kēia hihia e 300 W.

Like extrasystemic mana ana pa alima ka hoʻohana 'ana i ka volt-amperes. E ho'ā'o ka ho'ā'o'ana e hō'ike i nā ha'aka holo ka'a (nā'ea pū ka'a). 'O kēia ka palena kūpono loa i kahi e holo ai ka mea ho'oholo.

Eia kekahi,'o nā paepae voltage a me nā loina o kēia manawa aia i loko o nā palapala i ho'okomo'ia i nā papahana, a ua kākau'ia ma kona hale.

'O nā koina o kēia'ano kino, nā'ano o nā mea kani kelepona, hiki ke loa'a ma nā puke kiko'ī kūikawā. Eia kekahi la'ana, no nā ho'olālā'ana o ka hale,'o ka ikaika i kēia manawa ma ka laulā he'umikumamālima ampres ka ma'amau. No nā mea hana ikaika i ho'ohana'ia i loko o ka hale, hiki i kēia wā ke pi'i i 60 ampres. 'O ka luala uila i ka'eneke he 220 V.

Nā Hana Hana Makemakika

No ka ho'omaopopo'ana pehea e ho'olālā ai i ka'ai mana, e ho'ohana mākou i kekahi hi'ohi'ona pa'akikī. Ina he 220 V ka hoailona voltage o ke kikowaena, a ke holo nei ke kahe i ka circuit 2 A, alaila, o ka lilo ana o keia meakei e 440 W.

Pehea e ho'olālā ai i ke kaona o kēia manawa, inā hā'awi'ia ke kumukū'ai o kēia manawa? Eia kekahi la'ana, ma ke kaha o 48 W a me ka volta o 24 V e ho'oholo ai i ka ikaika i kēia manawa, pono'oe e māhele i ka nui o ka mana i ka volis. 'O ke ka'ina o ke kaapuni'o 2'A.

Pehea e ho'olālā ai i ka mana i kēia manawa, e'ike ana i ka mana? Hiki ke ho'oholo i ka lāpili'oi loa o ke kaapuni mai ka waiwai o ka mana a me ka volis. Kekahi la'ana, ma 100 W a me 2 V no ka helu'ana i kēia manawa, ua māhele'ia ka mana e ka volter, loa'a iā mākou he 50 A.

Nānā no ka helu'ana i ka lawe mana

E no'ono'o e pili ana i ka ho'olālā'ana i ka mana lawe o nā mea hana i ho'ohana'ia i ke ola o kēlā me kēia lā. 'O ka mua, e nānā pono'ia. Hō'ike pinepine i ka mana ma ke kino o ka mea hana, no ka mea ua kau ka mea ho'ohana i kahi kiko'ī kūikawā. He aha kāu e heluhelu ai ma kēia lepili? Ka nui o ka ikaika o kēia manawa, nā palena voltage, a me ka mana'oi o kēia pūnaewele. I kekahi mau kumu, ua hō'ike'ia kēia'ike e ka mea hana ma ka pāpale inoa o ka mea hana hale.

Lawe nā mea i ke kukui ma muli o ka mana o ka mana, i hō'ike'ia i kilowatts. 'O kona kumu kūpono e hō'ike ana i ka nui o ka mana i makemake'ia no ka hana pa'a o ka mea. Eia kekahi la'ana, no nā refrigerators home,'o kēia koho he 500 watts.

No ka mālama'ana i ka eletani a me ke kālā, he mea nui e hana i ka helu'ana. Pehea e ho'olālā ai i ka mana o ka ike i loko o ka hale? E no'ono'o kākou i kekahi'ano kiko'ī.

Ka helu'ana o nā kukui kukui

Eia kekahi la'ana, i ka ho'ohana'ana i'elua mau kukui kukui me ka mana o 100 W a me 23 W, hiki iā'oe ke loiloi i ka pono waiwai o ke kū'ai'ana i ke kukui o ka mana ha'aha'a. E ho'ā'o kākou e ho'ākāka i kēia mana'o ma kahi helu ma'amau. No laila, i ka unuhi'ana mai kahi ho'ohālikelike li'ili'i, loa'a iā mākou kahi'oko'a o 77 V. Inā e uku ana i ka helu no ka pau'ana o ka manaea uila, e hana'ia nā uku ma muli o ka pau i ka kW / h. Ke ho'omehana'ia nā kukui no ka manawa lō'ihi, hiki nō, ma ka ho'onui'ana, e ho'oholo i ka'oko'a o ka uku no ke kukui 23 a me 100 watt.

No ka ho'omaopopo maika'i'ana i ke'ano o ka ho'olālā'ana i ka'ai mana, e lawe kākou i kahi hi'ohi'ona i ka manawa e ho'ohana ai ke ke'ena i nā kukui kukui he'umi,'o kēlā me kēia mea he 100 watts.

'O ka nui,'o nā kukui e ho'opau i ka 1000 W,'o ia ho'i, 1 kW. Inā no ka makahiki e puhi lākou i 2000 mau hora,'o ia 2000 2000. Ma ke kauka kū'ai he ho'okahi kilowatt-hora 5 mau pu'uwai e uku ai no ka ho'ohana'ana i nā kukui he 50,000 rubles. I mea e hō'emi ai i nā koina ho'ona'auao, ua lō'ihi nā loina o nā hale noho a me nā hale i ho'olālā i nā kukui mālama ola.

Hiki i kekahi mau mea'ai ke ho'olālā i ka manahuulina ma muli o ka hana'ole, akā e ho'omau i ka pūnaewele. Inā ho'omau ka ho'omau'ana o ka LED i ka'ōpili, e hō'ike ana kēia e ho'opau'ia ana kekahi mana.

Ke ho'ohālikelike i ka lawe'ana o ka mana e like me ke kumuhana, pono loa ka hopena. Nolaila, i ka hihia inā pono e loa'a ka hopena pono, ua ho'ohana'ia nā wattmeters.

Ka Hopena

Ma muli o ka ho'onui pinepine o nā kumukū'ai no ka uila,'o nā hihia e pili ana i ka helu'ana i ka'ike mana, e'imi ana i nā'ano e ola ai, ua kūpono a pili.

'O nā mea hana maika'i o nā hale ho'okipa a me nā hale noho'āina e ho'ā'o e nānā mua i ka ho'ohana'ana i nā pūnaewele i kū'ai'ia i mea e uku'ole ai i nā uku nui no ke kukui ma hope. Apau e huli i ka huina mana hokii o ka uila ikehu no kanaka wahi hana ma ka manao ke kahua electrification nenoaiu. I kēia hihia,'a'ole hiki iā'oe ke pale wale i nā kumukū'ai e pono'ole no ka ikehu elekene, akā e pale i ka ho'oulu'ana, hiki ke alaka'i i ka ho'opili'ana o nā mea hana a me ke ahi.

Ma waena o nā pono o ka hale e pono e mālama'ia i ka helu'ana i ka mana piha,'ike mākou i nā kukui a me nā mea kukui, ka mea'aila kukui, ka mea e ho'oma'ema'e ai i ka mea'ai, ka mīkini pa'akai,

Ua hana'ia kēlā me kēia mea no ka ho'ohana'ana i kekahi'ano kūlana,'o ia ho'i, e "ho'okomo'ia" i loko o ka pahu loa'a no ka ikehu hili. 'O ke ala ma'alahi loa e loa'a ai nā kālā i loko o ka waihona kālā'ohana, hiki ke no'ono'o'ia ka kū'ai'ana i nā mea hana no ka home, me kahi papahana mālama ola A ++.
