Ib qho piv txwv ntawm Kev Xaiv Cov Khoom Siv Hluav Taws Xob rau Kev Tswj Tsav Tsheb (mos pib)

Peb-theem thyristor rectifier choj yuav tsum tau tswj lub DC lub cev muaj zog.Cov cuab yeej tsim nyog yog ib qho tseem ceeb kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm qhov muag muag los tswj lub cev muaj zog thiab nws yuav tsum tau xaiv los ua ke nrog cov cuab yeej ntawm lub cev muaj zog thiab qhov yuav tsum tau ua ntawm qhov system.Txoj cai xaiv tau muab raws li hauv qab no:

1.Condition: input voltage Vkab= 380V (3N 50Hz), tso zis DC tam sim no Id= 3600A, txias hom ntawm thyristor yog cua txias, ib puag ncig kub TA= 40 ℃, qhov xav tau surge tam sim no ITSM= 20 KAB.

2.Selection ntawm voltage: ncov tus nqi ntawm rated kab voltage

VD(max)=*VI= * 380 = 537V, kev tiv thaiv kev cuam tshuam coefficient yog suav tias yog 2.5, cov qauv los suav cov qib voltage yog: VDSM≥537V * 2.5 = 1343V, yog li

VDSM= VRSM= 1400V.

3.Kev xaiv tam sim no: vim yog cov qauv ntawm thyristor sib txawv ntxiv rau qhov sib txawv tam sim no, yog li peb yuav tsum suav cov nqi tam sim no los ntawm thyristor nrog Vrrm = 1400V.Kuvd= 3600A, qhov nruab nrab tam sim no dhau los ntawm txhua tus thyristor IT= 1200A, qhov ntsuas tam sim no ntawm thyristor IT (AV)= 1200A * 2.5 = 3000A.

4. Xws li cov cua txias heatsink yuav raug xaiv raws li tus qauv ntawm thyristor.

5.Lub thyristor thiab heatsink yuav tsum raug xaiv los tiv thaiv daim ntawv thov thiab cov ncauj lus kom ntxaws txog kev tswj lub cev muaj zog.Cov theem tswj thyristor thiab heatsink tsim los ntawm Jiangsu Yangjie Runau Semiconductor Co yog kev koom ua ke nrog lub xeev ntawm cov txuj ci thev naus laus zis ntawm kev tsim hluav taws xob semiconductor ntaus ntawv.Nws yog dav siv nyob rau hauv lub cev muaj zog kis tau tus mob daim ntawv thov.Thov hu rau peb cov kws tshaj lij los xaiv qhov tsim nyogthyristorthiabheatsinkrau qhov ua tau zoo tshaj plaws ntawm koj daim ntawv thov.
