Kev ua haujlwm ntawm lub zog transformer

Fais fab transformers yog ib qho ntawm cov khoom siv tseem ceeb hauv cov chaw tsim hluav taws xob thiab cov chaw ua haujlwm. Transformers ua haujlwm ntau yam: lawv tsis tsuas yog nce qhov hluav taws xob kom xa hluav taws xob rau cov neeg siv khoom siv, tab sis kuj txo qis kom tau raws li ntau qib kev siv. Hauv luv luv, ob theem voltage-nce thiab qib-down yuav tsum ua tiav los ntawm transformers. Thaum lub sij hawm sib kis ntawm hluav taws xob hluav taws xob hauv lub zog hluav taws xob, ob qho tib si hluav taws xob thiab hluav taws xob poob inevitably tshwm sim. Thaum xa cov hluav taws xob tib yam, qhov hluav taws xob poob yog inversely proportional rau qhov voltage, thiab lub zog poob yog inversely proportional rau lub square ntawm voltage. Siv cov khoom siv hluav taws xob los nce qhov hluav taws xob txo qis kev sib kis.

Lub transformer muaj ob los yog ntau dua coil windings raug mob ntawm tib lub tub ntxhais hlau. Cov windings yog txuas nrog ib qho chaw sib nqus sib nqus thiab ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Qhov chaw teeb tsa ntawm lub tshuab hloov pauv yuav tsum xav txog qhov yooj yim ntawm kev ua haujlwm, kev saib xyuas, thiab kev thauj mus los, thiab yuav tsum tau xaiv nyob rau hauv qhov chaw nyab xeeb thiab txhim khu kev qha. Thaum siv lub tshuab hloov pauv, nws cov peev txheej ntsuas yuav tsum raug xaiv kom tsim nyog. Thaum lub tshuab hluav taws xob ua haujlwm nyob rau hauv tsis muaj -load, nws yuav tsum muaj ntau lub zog reactive. Lub zog reactive no yuav tsum tau muab los ntawm lub hwj chim mov system. Xaiv lub transformer nrog lub peev xwm loj heev tsis tsuas yog nce kev nqis peev hauv thawj zaug xwb tab sis kuj tseem ua rau lub tshuab hloov pauv ua haujlwm nyob rau hauv tsis muaj -load lossis lub teeb- thauj khoom rau lub sijhawm ntev. Qhov no ua rau kom tsis muaj{10}}load poob, txo lub zog qhov tseem ceeb, thiab ua rau kev poob hauv lub network, ua rau kev lag luam tsis muaj txiaj ntsig lossis muaj txiaj ntsig. Hloov pauv, xaiv lub transformer nrog lub peev xwm me me heev yuav ua rau nws dhau mus rau lub sijhawm ntev, ua rau cov khoom puas tsuaj. Yog li ntawd, lub peev xwm ntsuas ntawm lub transformer yuav tsum raug xaiv raws li qhov yuav tsum tau muaj hluav taws xob thauj khoom thiab yuav tsum tsis txhob loj dhau lossis me dhau.
