Maxaan ku sameeyaa ilaalinta xad dhaafka ah marka foornada dhalinta dhalaalaysa ma ku jirtaa koronto buuxda?

1. ifafaale guul darro

Inverter-ku wuu guuldarraystaa marka awoodda soo noqnoqda ee dhexdhexaadka ah ay soo baxdo koronto buuxda, iyo ilaalinta xad-dhaafka ah ayaa la hawlgeliyay. Marka ay soo baxdo koronto yar, inta jeer ee dhexdhexaadka ah ayaa si lama filaan ah hoos ugu dhacaya, Ua hoos u dhaca iyo Id ayaa kordha.

2. Falanqaynta iyo daawaynta fashilantay

Marka loo eego ifafaalaha khaladka ah, waxaa horudhac loo xukumay in hal gacan biriij ee buundada rogaal-celinta aysan ahayn mid shaqaynaysa. Haddii cududda buundada lambarka 3 aanay soconayn, cududda 4-aad lama dami karo.

Ku-fiirsashada U4 oo leh oscilloscope sidoo kale waa xariiq toosan. Voltage of No. 3 cududda buundada waxay la mid tahay korantada culeyska, sidaas darteed qaabka U3 waa mawjadda sinaha oo dhamaystiran. Marka cilada kor lagu soo sheegay ay dhacdo, marka hore go’aami in thyristor uusan soconin ama qaybta kale ee cududda buundada ay furan tahay.

Haddii thyristor uusan sameynin, oscilloscope-ka ayaa loo isticmaali karaa si loo sii go’aamiyo in wareegga kiciya uu khaldan yahay, tiirka kantaroolka thyristor uu khaldan yahay, ama khadka ayaa khaldan.

Marka hore isticmaal oscilloscope si aad u hubiso in garaaca garaaca wadnaha ku yaal cududda buundada iyo in garaaca kiciya uu caadi yahay. Haddii garaaca garaaca wadnaha aanu caadi ahayn, ciladdu waxay ku jirtaa wareegga kiciya. Dareemaha waa in lagu dhejiyaa booska kormeerka, iyo qaab-dhismeedka mawjadaha qayb kasta oo ka mid ah wareegga kicinta waa in tallaabo-tallaabo loo eego si loo helo cilladda. dhibic. Haddii garaaca garaaca garaaca wadnaha uu yahay mid caadi ah, isticmaal multimeter si aad u hubiso in tiirka xakamaynta thyristor uu furan yahay ama gaaban yahay.

Haddii ay caadi tahay, hubi iska caabbinta u dhaxaysa korantada kontoroolka iyo cathode ee thyristor. Haddii caabbinta gudaha ee tiirka kantaroolku aad u weyn yahay, beddel thyristor.

Haddii thyristor-ku uu si joogto ah u maqan yahay, hubi in kooxda thyristors ee maqan ay yihiin kuwo wareegsan. Haddii ay caadi tahay, hubi in wakhtiga daminta thyristor uu aad u dheer yahay iyo in kale.
