Qhov kev kuaj tsis muaj load ntawm lub transformer yog hais txog qhov active poob uas tshwm sim thaum lub thib ob sab ntawm lub transformer yog qhib thiab cov rated voltage ntawm lub rated zaus yog siv rau thawj winding.
Thaum lub ntsuas hluav taws xob raug siv rau hauv thawj qhov cua, qhov sib nqus sib nqus flux yog tsim nyob rau hauv cov tub ntxhais hlau, uas ua rau hysteresis thiab eddy tam sim no poob hauv cov tub ntxhais hlau, uas yog hu ua hlau poob.
Qhov tsis muaj-load tam sim no thiab qhov tsis kam ntawm thawj winding yog qhov me me, qhov tsis kam ntawm cov thawj winding yog negligible, thiab tsis muaj-load poob ntawm transformer yog yeej sib npaug ntawm cov hlau poob.
Qhov tsis muaj-load poob ntawm lub transformer feem ntau tuaj yeem xam los ntawm kev ntsuas tsis muaj load.
Qhov loj ntawm qhov tsis muaj qhov poob yog cuam tshuam nrog cov yam ntxwv xws li lub peev xwm hloov pauv, cov qauv hluav taws xob sib nqus, cov ntawv silicon steel zoo, thiab lwm yam, thiab feem ntau yog nyob ntawm chav tsev poob ntawm cov khoom siv hlau, xws li: tsis muaj qhov poob-hluav taws xob steel. sheet unit poob × hlau core hnyav.
Thaum qhov hluav taws xob ntawm cov khoom siv hluav taws xob tsis tu ncua, qhov loj ntawm qhov tsis muaj kev thauj khoom yog qhov tseem ceeb, tsis hais qhov loj thiab qhov xwm txheej ntawm qhov load.
Qhov luv luv-circuit poob ntawm lub transformer yog dab tsi?
Lub hauv paus thiab theem nrab windings ntawm lub transformer muaj ib tug tej yam kuj, thiab thaum lub tam sim no ntws, ib tug npaum li cas ntawm lub hwj chim poob yuav tshwm sim.
Lub luv luv-circuit poob ntawm lub transformer yog sib npaug rau cov sum ntawm lub zog noj nyob rau hauv lub tsis kam ntawm lub thawj thiab thib ob windings thaum lub thib ob sab ntawm lub transformer yog luv luv thiab lub luv luv-circuit tam sim no ntws los ntawm thawj sab yog lub ntsuas tam sim no. Tsis quav ntsej cov hlau poob hauv lub xeev luv luv, vim tias qhov winding feem ntau yog ua los ntawm tooj liab hlau, nws tseem hu ua tooj liab poob.
Qhov loj ntawm qhov luv luv-circuit poob yog cuam tshuam nrog qhov loj ntawm lub load, load kev ua tau zoo thiab winding kub. Qhov loj ntawm qhov luv-circuit poob yog proportional rau lub square ntawm tam sim no los ntawm thawj thiab theem nrab windings, thiab luv luv-circuit poob yog txuam nrog qhov loj thiab qhov xwm ntawm lub load.
Qhov luv luv-circuit poob (kw) qhia rau ntawm daim ntawv teev npe yog hais txog tooj liab poob ntawm winding ntawm 75 degree thiab qhov ntsuas tam sim no dhau. Qhov loj ntawm qhov luv luv-circuit poob yog cuam tshuam nrog qhov kub thiab txias ntawm winding.
Cov saum toj no yog qhov tsis muaj load poob sim ntawm transformer, thiab cov kev paub txog ntawm lub luv luv-circuit poob ntawm transformer, kuv vam tias nws yuav pab tau rau txhua leej txhua tus.
