Txoj haujlwm ua haujlwm thiab lub luag haujlwm tseem ceeb ntawm thyristor

1. Txoj haujlwm ua haujlwm ntawm tus kws kho mob yog:

1. Txhawm rau kom thyristor tig, ib qho yog siv qhov hluav taws xob rau pem hauv ntej ntawm nws qhov anode A thiab cathode K, thiab lwm qhov yog txhawm rau ntsuas qhov ntsuas hluav taws xob zoo ntawm nws cov tswj hluav taws xob G thiab cathode K. Tom qab lub thyristor tau qhib, tso lub khawm hloov, tshem tawm qhov ntsuas hluav taws xob, thiab tseem tswj hwm lub xeev.

2. Txawm li cas los xij, yog tias siv hluav taws xob thim rov qab siv rau anode lossis tswj hluav taws xob, lub thyristor tsis tuaj yeem qhib. Lub luag haujlwm ntawm tus ncej tswj yog tig rau lub thyristor los ntawm kev thov lub plawv dhia zoo, tab sis nws tsis tuaj yeem tua. Tua tawm qhov kev coj ua thyristor tuaj yeem txiav tawm cov khoom siv hluav taws xob anode (hloov S hauv Daim Duab 3) lossis ua kom cov anode tam sim no tsawg dua tus nqi tsawg kawg rau kev tswj xyuas (hu ua kev txhawb nqa tam sim no). Yog tias AC voltage lossis pulsating DC voltage tau siv nruab nrab ntawm anode thiab cathode ntawm thyristor, thyristor yuav tua nws tus kheej thaum qhov hluav taws xob hla xoom.

2. Lub luag haujlwm ntawm thyristor hauv Circuit Court muaj raws li hauv qab no:

1. Converter/rectifier.

2. Kho qhov siab.

3. Kev hloov pauv zaus.

4. Hloov.

Ib qho tseem ceeb tshaj plaws ntawm SCR yog ua kom ruaj khov tam sim no. Thyristors tau siv dav hauv kev tswj tsis siv neeg, cov tshuab hluav taws xob, kev tsim hluav taws xob thiab khoom siv hauv tsev. Lub thyristor yog lub zog hloov pauv tseem ceeb. Feem ntau nws tau khaws cia hauv lub xeev tsis dhau mus txog thaum nws tau tshwm sim los ntawm lub teeb liab tswj qis lossis “taws” kom ua rau nws dhau mus. Thaum nws tau taws, nws yuav nyob twj ywm txawm tias lub teeb liab raug tshem tawm. Hauv lub xeev cov channel, txhawm rau txiav nws tawm, qhov rov qab siv hluav taws xob tuaj yeem siv nruab nrab ntawm anode thiab cathode lossis tam sim no ntws los ntawm thyristor diode tuaj yeem txo qis qis dua tus nqi.
