Kev piav qhia Advanced ntawm lub zog qhov tseem ceeb ntawm induction melting rauv

Kev piav qhia theem siab ntawm lub hwj chim ntawm induction melting rauv: Nyob rau hauv inductive load Circuit Court, lub ncov tus nqi ntawm tam sim no waveform tshwm sim tom qab lub ncov nqi ntawm lub voltage waveform. Kev sib cais ntawm qhov siab tshaj plaws ntawm ob lub waveforms tuaj yeem qhia tau los ntawm qhov muaj zog. Qhov qis zog qhov tseem ceeb, qhov ntau dua qhov sib cais ntawm ob lub waveform peaks. Paulkin tuaj yeem nqa ob lub ncov los ze zog ua ke dua, yog li txhim kho kev ua haujlwm ntawm lub cev.

Lub zog tseem ceeb yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm AC circuits. Cov theem ntawm lub zog yog qhov tseem ceeb heev rau kev siv thiab kev tsom xam ntawm cov hluav taws xob induction melting rauv, nrog rau kev kawm txog kev siv hluav taws xob thiab lwm yam teeb meem. Lub zog hluav taws xob yog hais txog lub cosine ntawm theem sib txawv ntawm qhov voltage U ntawm ob qho kawg ntawm ob lub davhlau ya nyob twg network (ib lub voj voog nrog ob qhov kev sib cuag rau lub ntiaj teb sab nraud) thiab tam sim no kuv nyob hauv nws. Lub zog siv nyob rau hauv ob lub davhlau ya nyob twg yog hais txog lub zog nruab nrab, tseem hu ua lub zog nquag, uas yog sib npaug rau: P = UIcosΦ. Los ntawm qhov no, nws tuaj yeem pom tias lub zog P tau siv hauv Circuit Court tsis yog nyob ntawm qhov voltage V thiab tam sim no kuv, tab sis kuj tseem cuam tshuam nrog lub zog hluav taws xob. Lub zog qhov tseem ceeb nyob ntawm qhov xwm txheej ntawm qhov load hauv Circuit Court. Rau cov loads resistive, theem sib txawv ntawm qhov voltage thiab tam sim no yog 0, yog li lub hwj chim ntawm Circuit Court yog qhov loj tshaj (); thaum rau cov ntshiab inductive circuits, theem sib txawv ntawm voltage thiab tam sim no yog π / 2, thiab qhov voltage ua rau tam sim no; nyob rau hauv ntshiab capacitance Nyob rau hauv Circuit Court, qhov sib txawv theem ntawm qhov voltage thiab tam sim no yog – (π / 2), uas yog, tam sim no ua rau voltage. Hauv ob lub voj voog tom kawg, lub hwj chim yog xoom. Rau cov khoom siv hluav taws xob dav dav, lub zog hluav taws xob yog nruab nrab ntawm 0 thiab 1.
