Hana a me ka mana o ka uilaʻikena

Ma kēlā me kēia paʻa kaapuni compulsorily hoʻopaʻa papalua ikehu huli ana. Ma ka hooponopono hou ana i ka he kumu ua i mai o kekahi ikehu (e laʻa me, mīkini hana wāwahie - machining) i loko o uila ikehu, a me ka huakai kaapuni a kaʻikena ua hou hoohuliia i loko o ka ikehu hoʻokoe i kekahi? Ueo. Ana huli ana kaapuni uila kala pono i loko o kekahi o nā 'ano o ka ikehu - i ka waiwai o ka hana anakahi uila.

Akā, ua maopopo i ka hana a me ka mana o ka uila pono o ka hana ana o ka uila kahua ikaika, neʻe maila i ka 'āhewa' ana; no laila ia mea maʻalahi e hoʻomaulia.

Hana ma luna o ka hoololiia ana o ka uila mālama i loko o ka uila kahua aiee oaeuiinoe ma ka huina hoonui hoololiia ma ka waiwai o ka mālamaʻia oko ma waena o ka papa ma ka hoʻomaka a me ka hopena o ka hoolilo, a laila ma luna o ke anakahi uila:

A = qU.

ʻae nō hoʻi, i kēia lākiō i e pili ana i ka loiloi 'ana i manaÿo e like me ka hana a me ka mana o ka pila nui ʻikena. About ka nui o ka uku ole, hala i loko o ke kaula, ua hiki ke hoʻoponopono ma ka pono e kahe ana i loko o ka huakai kaapuni, a me ka manawa o kona hanana, e like me Q = It.

E ho ohana ia ka pilina, ua loaa i ka haʻilula ka haʻiʻana i ka waiwai o ka mea he hana ma kekahi wahi kaawale o ke kaula, me ka anakahi uila U:

A = UIt.

Hana a me ka mana o ka uila he ana me penei: ina ka he ana i amperes manawa i loko o kekona, a me ke anakahi uila ma Volts, o ka hana - i loko o joules (J).

Penei, 1 joule = 1 volt amperes m 1 m 1 kekona.

Mana ua anaia mai ka manawa e watts (W):

O 1 watt = 1 joule / 1 kekona, a 1 watt = 1 volt m 1 Amp.

I ka ninau o ka helu ana i ka waiwai o ka mea he hana i loko o kēia wahi pono unrelated i ka ninau o ka mea e huli 'ano o ka ikaika ma ka paena uila ikehu. Kēia hana o ka ana o ka mana, lilo iho i loko o nā 'ano apau loa.

Uilaʻikena e hali ana i hana ke hoʻa'ā i ka filament pu u kukui, heheʻe ke hooheheeia, ao ka ka armature o ka Hawaii, i Nine Inch huli ana, etc. Hana a me ka mana o ka uila pono i loko o nā hihia a pau, hooholo i ka nui o ka uila mana huli ana i loko o nā 'ano apau loa - me mechanical ikehu, i ka ikaika o thermal neʻeʻana, etc.

Ike i ka mana P = A / t, ke loaa i ka haʻilula ana i ka manaʻikena he pōpilikia ma ka hookahi paena kaula

P = UI.

Hana a me ka mana o DC hiki ke pōpilikia ma ka hoʻohana 'ana i kēia mau nā papakuhikuhi, a me ka ammeter, voltmeter. Ma ka hana pono, i ka hana o ka uila ke kahua ua anaia mai ka manawa ma kekahi kūikawā mea - loan. Maalo ae la oia ma ka mika, loko o ka mea, hoʻomaka e e holo Lightweight Aluminum pā hōkū, a me kona kuapo mämä holo ka pololei hapaʻauhau i ka amperage a me ka anakahi uila. I ka helu o ka Hope, aʻo ia e hana ai no kekahi manawa, e kōkua e hoʻoholo i ka hopena e pili ana i pono no keia manawa o ka hana. Uila mika Hiki ke loaʻa i loko o kēlā me kēia keʻena.

AC mana ua anaia mai ka hoʻohana 'ana i ka kūikawā mea - he mana mika. Ma ka nakeke o keia mea i hui kumu voltmeter a me ka ammeter.

He nui pou nā mīkini home a me oaoieei manaʻo hoike i ko lakou mana. , No ka laʻana, ka mana e lilo i incandescent u kukui 25 W, 75 W, etc., i ka mana o ka holo wahine holoi a me ka hao, a ma kahi o 1000 W, uila mana ke hiki kiʻekiʻe loa Hawaiʻi - mai i mau tausani kilowatts. Ma keia hihia, e malama i ka manao o kaʻikena nona iho, a hele ma kekahi lima kūlana kiʻekiʻe.

Hana a AC mana i mau hōʻailona i okoa. Pela, e hoʻomaulia i ka hana i hanaia ma ka alternating pono no i kekahi wa o ka manawa, i kekahi ke hoʻohana i ka haʻilula:

P = 1 / 2I₀U₀ cos φ. Pinepine keia helu kaulike ua palapala i loko o kēia palapala: P = Iu cos φ, kahi au a me ka U - cia o ke anakahi uila a me ka papa, i mea 2 manawa uuku ma mua o ka AYEIE ikaika hawewe loina.

Ke haʻilula no ka helu ana i ka AC mana o ka ia me ia no ka mea DC.

Unit o ka ikaika a me ka hana:

1 watt-kekona = 1 J 1 WH = 3600 J;

Hectowatt 1 hola J = 360.000;

1 kWh = 3600000dzh.

Units o ka mana:

1 ampere volt = 1 W;

1 hectowatt = 100 W;

1 kilowatt = 1000 watts.
