Alternating uila au i

Alternating uilaʻikena - pono me ka olelo manawa-e loli iki ana a me ka ikaika. O ka poe au i hoano e wale ma ka nui, i kapaʻia pulsating. I ka hana a me ka maʻamau o ke ola ua loa pinepine hoʻohana alternating sinusoidalʻikena.

Hoʻololi ' DC i AC uila hiki ke hana penei. Ua waiho ihola i loko o kaʻaʻahu kūpaʻaʻume mākenēki kahua'ōwili hao o ka uea. Me kaʻaʻahu kuapo o ka'ōwili hao e pili ana i ka iho (axis) o kaʻume mākenēki koko , e noke oko a ma ka nui a me ka ao ao. Nolaila, ma ke kānāwai o ka electromagnetic a hoʻokomo, he'ōwili hao ua hana ee iaaanu aey ma ka hema a me ka nui o ka electromotive ikaika (EMF). Inā ia i ka'ōwili hao i pili i ka mawaho kaapuni, a laila ka mea, ua loaa i kekahi alternating uilaʻikena.

A hiki i ka pelane o ke kaʻapuni'ōwili hao i ÷ haku me ka pili ana i ke kula laina o kaʻume mākenēki kula hele therethrough kaʻume mākenēki koko - ka nui (Φ = Φmax), i ka mämä holo o ka loli i loko o kona 'Aʻohe (ΔΦ / Δt = 0), e like me ka hele ana o ka oihana Guides kipi 'oihana o ka laina o ka ikaika, me ka holo ia. Nolaila, i ka hoʻokomo electromotive ikaika i hanaʻia i loko o ka'ōwili hao i Aʻohe (E = 0).

A hiki i ka'ōwili hao pelane mea ia laua a hiki i ka laina o ka ikaika, koko penetrating ka mea, ua like pu ia 'Aʻohe (Φ = 0), i ka uku o ka loli ana o kona i kā mākou i loko o kēia wahi ((ΔΦ / Δt) max), mahope mai o ka'ōwili hao conductors e neʻe maila p ÷ haku i ka laina o ka poe ikaika no lakou.

Electromotive ikaika i kupu mai ma keia hihia i loko o ka loop, i ka i kā mākou waiwai (E = Emax). I hou kuapo o Kahualoa Kokohi māmā loli koko penetrating i ka'ōwili hao, e mahuahua; nolaila, e mahuahua EMF i loa waiwai mai ka 0 a hiki i Emax. Penei, o ka nui o ka emf e poloʻai pule ma ka kaʻapuni'ōwili hao no kipi hoʻololi mai kona -Emax a hiki i + Emax.

Us hamama'ōwili hao uea, a paʻa ia i ka oscilloscope. A hiki i ka'ōwili hao ke ka ao kaʻume mākenēki kahua, ka oscilloscope e palapala i nā hoʻololiʻikena, a e e hookolokoloia mai ai au, a me ka loli ana o ka electromotive koa i loko o ka loop i kekahi pōʻaiapuni.

Ke au i ua loaʻa i loko o ka'ōwili hao i konaʻaʻahu maikaʻiʻole i loko o kaʻaʻahuʻume mākenēki ke kahua, e like me ka hoike ma ka waveform loli aʻe sinusoidally. Ua kapaʻia kēiaʻikena alternating sinusoidal.

Ke au o ka manawa no a ka electromotive ikaika hanaʻia kekahi oscillation, i kapaʻia ka wā o ka AC.

Ka huapalapala mua inoa oscillation au - T. Ka helu o oscillations no 1 lua - ka he alapine, a ua hoʻokohu 'ia e ka palapala. F. Kona pa alima o ana - Hertz (Hz):

. f = 1 / T, a T = 1 /. f.

Inā i ka waiwai o ka EMF i kekahi ākeʻakeʻa kumu manawa ua denoted ma ka E (kona instantaneous waiwai), a me ka nui waiwai (piko) - ma ka Emax, i ke kānāwai ka haʻiʻana i ke kaukaʻi mea, mai ka manawa i ka manawa, hiki ke kaheaia like me ka hahai ana i olelo i loko o ka hihia o ka sinusoidalʻikena.

E = Emax˖sin (2 / T) 'ole.

Ma ka hapanui o nā'āina, a me ka hanalima eeuo ana alternating uila kala pono me ka alapine (frequency) o 50 Hz, ka lōʻihi o ka wā o 0,02 kekona.

E hoomakaukau ai no ka alternating uila pono, mai ka mea me mechanical ikehu ua hana ma ka mea o kūikawā machines, i ka poe i kaheaia nā mīkini uila. I ka rula o ko lākou hanaʻana - i ke kānāwai o ka electromagnetic a hoʻokomo. Ka loa alodio oscillator kaapuni i e na poe like me ka kapiliia kaʻapuni a puni ka iho (axis) i loko o kaʻume mākenēki kahua o ka electromagnet a me ka mau Mākēneki. A hiki aku oe i ka ao ke kino i hana ia e ka ee iaaanu aey electromotive ikaika i loko o laila. Ma ka ai pili aku i ke kino a hiki i ka mawaho kaapuni, ua loaa i ka alternating uilaʻikena. An alternator me kaʻume mākenēki'ōnaehana wahi a kaʻapuni coils kūkulu infrequently.

Kokoke a pau o ka mīkini hana wāwahieʻanuʻu (heleuma) ua kau wahi, a me ka Mākēneki nenoaia (inductor) ua ke ka ao. Oni ole hapa o ka mīkini hana wāwahie ua kapaia he stator, a hoʻoneʻe - epaepa huila.
