Kev xav ntawm induction cua sov cua sov

1. Lub zog hluav taws xob ntawm lub qhov cub hluav taws xob induction yog peb-theem alternating tam sim no, zaus yog 50Hz, thiab cov khoom siv hluav taws xob yog 380V. Rau high-power induction cua sov rauv, lub input voltage kuj yog 660V, 750V, 950V, thiab lwm yam.

2. Lub tshuab cua sov induction yog siv los ntawm lub tshuab hluav taws xob, uas tuaj yeem muab faib ua ob hom: qhuav-hom transformers thiab roj-txias transformers raws li qhov sib txawv ntawm cov cua txias. Hauv induction cua sov cua sov kev lag luam, peb pom zoo cov roj-txias rectifier transformers.

3. Nyob rau hauv qhov ntsuas hluav taws xob lossis ntsuas qhov ntsuas, qhov tso zis hluav taws xob ntawm lub qhov cub hluav taws xob induction tuaj yeem hloov kho tau yooj yim thiab tsis tu ncua, thiab qhov kev hloov pauv yog 5% -100% ntawm lub zog ntsuas;

4. Lub zaus hloov hluav taws xob lub txee ntawm lub qhov cub hluav taws xob induction yog cov khoom tseem ceeb, uas yog tsim los ntawm ob ntu: rectifier / inverter. Lub luag haujlwm ntawm lub rectifier ib feem yog cov txheej txheem ntawm kev hloov 50HZ alternating tam sim no mus rau hauv lub pulsating direct tam sim no. Raws li tus naj npawb ntawm cov pulse rectification, nws tuaj yeem muab faib ua 6-pulse rectification, 12-pulse rectification, thiab 24-pulse rectification. Tom qab rectification, ib tug smoothing reactor yuav txuas nrog nyob rau hauv series nrog tus ncej zoo. Lub luag haujlwm ntawm inverter ib feem yog hloov cov tam sim no ncaj qha los ntawm rectification rau hauv qhov nruab nrab zaus hloov tam sim no thiab tom qab ntawd muab lub zog rau lub kauj induction.

5. Thaum qhov tso zis hluav taws xob ntawm qhov hluav taws xob induction cua sov tshaj 1.1-1.2 npaug ntawm qhov siab tshaj plaws tso zis hluav taws xob lossis tshaj qhov ntsuas qhov ntsuas hluav taws xob, qhov kev tiv thaiv overvoltage yuav ua rau lub cuab yeej txiav tsis ua haujlwm thiab teeb tsa lub tswb – teeb tsa lub zog. overvoltage qhia lub teeb ntawm lub ntsuas lub thawv.

6. Lub capacitor txee ntawm induction cua sov rauv yog ib yam khoom uas muab reactive zog them rau lub induction kauj. Nws tuaj yeem nkag siab yooj yim tias tus nqi capacitance ncaj qha cuam tshuam rau lub zog ntawm cov khoom siv. Thaum uas tig mus resonance induction cua sov rauv tsuas muaj ib hom resonance capacitor (hluav taws xob cua sov capacitor), thaum lub series resonance induction cua sov rauv muaj lim capacitors ntxiv rau resonance capacitor (hluav taws xob cua sov capacitor).

7. Thaum tus choj inverter ntawm qhov hluav taws xob induction cua sov yog txuas ncaj qha thiab luv luv, qhov kev tiv thaiv yuav ua tam sim ntawd kom nres lub cuab yeej txiav, thiab xa tawm ib qho kev taw qhia overcurrent – teeb lub overcurrent qhia lub teeb ntawm lub ntsuas ntsuas.

8. Thaum lub zog ua haujlwm ntawm cov dej txias ntawm lub qhov cub induction cua sov yog qis dua ib qho nqi, cov khoom siv cua sov induction, quenching cua sov cov cuab yeej, thiab quenching thiab tempering kub kho cov kab ntau lawm tuaj yeem nres thiab teeb tsa cov dej siab. qhov taw qhia ntawm lub vaj huam sib luag.

9. zaus conversion ntaus ntawv ntawm lub induction cua sov cua sov txais yuav thyristor SCR, uas yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob. Kev ua tau zoo ntawm cov thyristor xaiv yuav cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov khoom siv. Feem ntau siv thyristor kev faib tawm,

1) KP hom zoo tib yam thyristor, feem ntau siv hauv kev kho;

2) KK hom ceev thyristor, feem ntau siv hauv inverter;

1. KF hom asymmetric thyristor yog ib yam tshiab ntawm thyristor tsim nyob rau hauv xyoo tas los no, uas yog siv nyob rau hauv series inverter khoom.
