IiTransformers zoMgangatho waMandla kunye noSasazo

Ukusebenza kakuhle kwezikhululo ze-transformer ezisasazwayo kuchatshazelwa kakhulu ngumgangatho wamandla. Ezi transformer, eziyinxalenye ebalulekileyo yenkqubo yokusasazwa kombane, ziguqula umbane we-voltage ephezulu ube ngamanqanaba aphantsi e-voltage afanelekileyo kwiizicelo zokugqibela. Ukusebenza kakuhle kunye nokusebenza kakuhle kwezi transformer kuxhomekeke kakhulu kumgangatho wamandla abawafumanayo.

Umgangatho wamandla ophantsi, obonakaliswa kukwehla kwamandla ombane, ukudumba, iiharmonics, kunye nokuqhawuka, kunokukhokelela ekwandeni kwelahleko kwiitransformers zokusasaza amandla. Ezi lahleko zingahlulwa zibe ziintlobo ezimbini: ilahleko eziphambili kunye nelahleko zekopolo. Ilahleko eziphambili zenzeka ngenxa yokwahluka kwintsimi yemagnethi ngaphakathi kwesiseko setransformer, ngelixa ilahleko zekopolo zenzeka ngenxa yokuxhathisa kwee-windings zetransformer. Zombini ezi lahleko ziyanda phantsi kweemeko zomgangatho wamandla ophantsi, nto leyo ekhokelela ekwehleni kokusebenza kakuhle kwetransformer.

IiHarmonics, inkalo ebalulekileyo yomgangatho wamandla, zinempembelelo enkulu kwixesha elide kwiitransformer ezisasazwayo. IiHarmonics zibhekisa ekuguqulweni kwesimo se-waveform yombane eqhelekileyo, ngokuqhelekileyo ngenxa yokusebenza kwemithwalo engangqalanga efana neekhompyutha, izibane ze-LED, kunye nee-variable speed drives. Ezi mpazamo zinokubangela ukwanda kobushushu kwitransformer, nto leyo ekhokelela ekugugeni ngokukhawuleza kunye nokuncipha kobomi bezixhobo.

Ngaphezu koko, iiharmonics zinokunyusa imfuno yamandla kunye nokulahleka kwenkqubo. Zinokugqithisa i-transformer kunye nezinye izinto zenkqubo yombane, nto leyo ekhokelela ekuphulweni kwangethuba kwaye kufuneke ukulungiswa okanye ukutshintshwa okubiza kakhulu. Ngoko ke, ukulawula iiharmonics yinxalenye ebalulekileyo yokugcina umgangatho ophezulu wamandla kunye nokuqinisekisa ukusebenza ngokufanelekileyo kwamandla. ii-transformer zokusasaza amandla .

Umgangatho wamandla udlala indima ebalulekileyo ekusebenzeni nasekuhlaleni ixesha elide kwesitishi sokuhambisa iitransfoma. Umgangatho wamandla ophantsi unokukhokelela ekulahlekelweni okwandileyo, ekunciphiseni ukusebenza kakuhle, kunye nobomi obufutshane bezixhobo. Ke ngoko, amaqhinga asebenzayo olawulo lomgangatho wamandla ayimfuneko ekusebenzeni kakuhle kweetransfoma ezisasaza.

Ukusebenza kweHarmonics kunye neTransformer

Imisinga yeHarmonic, ingakumbi leyo ikwiifrequency eziphezulu, inokuchaphazela kakhulu ukusebenza kweetransformer. Le misinga iveliswa yimithwalo engeyiyo emgceni efana neekhompyutha, ii-variable speed drives, kunye neentlobo ezithile zeenkqubo zokukhanyisa, nto leyo ebangela ukuphazamiseka kwi-sinusoidal waveform yombane.

Xa la mandla e-harmonic ehamba nge-transformer, anokubangela ilahleko eyongezelelekileyo ye-core ngenxa ye-hysteresis kunye ne-eddy currents. Ilahleko ye-Hysteresis inxulumene ne-magnetization kunye ne-demagnetization yezinto eziphambili ze-transformer ngokuphendula kwi-alternating current. Ilahleko yamandla e-Eddy yenzeka xa i-induction currents ijikeleza ngaphakathi kwezinto eziphambili, idala amasimi emagnethi asekuhlaleni achasene ne-main field. Zombini ezi lahleko ziyanda ngokuphindaphindeka kwamandla ombane. Ke ngoko, i-harmonic currents ephezulu inokukhokelela kwilahleko ephezulu kakhulu ye-core, inciphise ukusebenza kakuhle kwe-transformer kwaye ibangele ukuba ishushu kakhulu, nto leyo enokunciphisa ubomi bayo.

Zininzi izinto ezinokuchaphazela umgangatho wamandla kwiintambo zothumelo. Ezi ziquka:

1. Iimpawu zoMthwalo: Imithwalo engekho mgca inokuvelisa ii-harmonics eziphazamisa i-voltage kunye ne-current waveforms, ezichaphazela umgangatho wamandla.
