The reactance inductive ho lenaihana oa potoloho

Hanyetsa ka potoloho ea motlakase ke oa mefuta e 'meli - mafolofolo le arabelang. Active emeloang resistors, litleloubu, futhumatsang makhetlo 'me joalo-joalo. Ka mantsoe a mang, likarolo tsohle tse ho phalla jwale ka ho toba o etsa mosebetsi e metle kapa, ka nyeoe e' ngoe e khethehileng, ho hlahisa a lakatsa futhumatsang mokhanni. Ka lehlakoreng le leng, sefofane sa jete - sekhele telele. Le bolela ho capacitive le inductive reactance. Likarolo oa potoloho ho ba le reactance, ho feta ha jwale motlakase teng tse sa tšoaneng lipakeng eneji, le ho sokoloha. capacitor A (capacitance) bakoang ke ho tefo, 'me joale o romela ho ea sekgoqetsane. Mohlala o mong o - ya inductive reactance ea kela ho, moo karolo ea matla a motlakase e fetoloa tšimo a khoheli a.

Ha e le hantle, "e hloekileng" kapa reactances a sebetsang a ke ke. Kamehla le karolo fapaneng hona joale. Ka mohlala, ha bala ka lithapo tsa mela e telele-hole matla, hlokomele se feela ho hanyetsa, empa hape capacitive. Le ho hlahloba reactance inductive, e lokela ho a hopola hore conductors bobeli le phepelo matla a ho etsa liphetoho tse itseng dipalelo ena.

Ka ho ikemisetsa ho hanyetsa kakaretso ea potoloho karolo, ho ke ho hlokahala hore mene metsoako e mafolofolo le arabelang. Ho feta moo, ho fumana chelete e tobileng ea e tloaelehileng tshebetso thuto ea lipalo khonehe, kahoo sebelisa thutatekanyo (vector) tsela ea ho haha. Haha e triangolo tokelo eo cathetus tse peli ba mafolofolo le inductive impedance, le hypotenuse - feletseng. Bolelele ba likarolo e tsamaisanang le melao ea boitšoaro ea morao-rao.

Nahana inductive reactance ho lenaihana potoloho. Emela ea potoloho e bonolo o nang le matla ao a tsoa mohloling (emf, E), e resistor (resistive motsoako, R) le kela (bottom, L). Ho tloha reactance inductive ke ka lebaka la ho intša susumetsoa EMF (E B) ka chenchana oa kela ho, ho totobetse hore ho eketsa le bottom potoloho le keketseho ea boleng ba jwale phallang ka oa potoloho ena.

molao Ohm bakeng sa balebeli ba potoloho ena shebahalang joaloka:

E + E B = Ke * R.

Ka mor'a ho beha nako sehlahisoa sa jwale (Ke PR) ho a bale intša induction:

E Si = -L * Ke Rd.

"-" letšoao ka abel a bontša hore phello ea E Si lebisitsoe ho fetola boleng jwale. Lenz puso ea bolela hore ha ho na le phetoho efe kapa efe ya ho hona joale intša susumetsoa EMF. Ho tloha ka liphetoho tse joalo ka lipotoloho lenaihana e leng ba tlhaho (le ke kamehla), ho E B e bopa e hanyetsa mohlomong kapa hore ho hanyetsa 'nete hape. Tabeng ea matla ao a tsoa mohloling oa morao-rao ka ho toba , kamano ena e sa kgotsofala le ha ba leka ho amahanya kela (bottom) ka potoloho e joalo e ne e tla 'short-oa potoloho hlahile khale

Ho hlōla E B phepelo matla lokela hlahisa phapang e 'nang ka se fumaneng kela hore ho ne ho lekane, bonyane ka E Si hanyetsa matšeliso. Ho latelang:

U = -SU katse Si.

Ka mantsoe a mang, ho gagamalo ka mose inductor ke numerically lekanang le lebotho la electromotive ho intša induction.

Ho tloha ka ho eketseha hona joale ka oa potoloho eketsa ea matla a khoheli le eena chelete Eddy tšimo bakang hōla bottom countercurrent, e mong a ka bolella hore ho na le mohato battlefield pakeng gagamalo le hona joale. Kahoo karolo e le 'ngoe: hobane intša induction EMF thibela phetoho efe kapa efe ka morao-rao, ha ho eketsa (pele kotara nako ya sinusoid ka) stats tšimo e hlahisoang, empa ka hoetla (bobeli poleloana e reng) ho fapana le hoo - the hlohlelletsoa jwale ke codirectional le botlaaseng. Ke hore, haeba postulate boteng ba se setle sa matla a tsoang mohloling ntle ho hanyetsa ka hare le bottom kantle ho motsoako ba mafolofolo, ho thothometsa eneji, le "mohloding - kela" ka etsahala ho sa feleng.
