isiphumo sobushushu kuvavanyo loxinzelelo oluphezulu

Utshintsho lobushushu luya kuyichaphazela ngokupheleleyo imeko yokumelana nobushushu, ngoko ke xa ubushushu bangaphandle buqhubeka bunyuka, intshukumo yeemolekyuli kunye nee-ion kwizinto zokuthintela ubushushu iya kuqhubeka ikhawulezisa isantya sokuhamba kunye nokunyuka kobushushu, okuya kukhokelela ekubeni i-polarity yokumelana nokuthintela ubushushu iphuculwe, kwaye ukumelana nokuthintela ubushushu kuncitshiswe. Kwangaxeshanye, kwinkqubo yokunyuka kobushushu, isantya sokuhamba kweemolekyuli zamanzi kwimeko yokuthintela ukuthintela ubushushu siya kuqhubeka sikhawuleza, ukuze ukungcola kumphezulu wokumelana nokuthintela ubushushu kunyibilike ngokukhawuleza, ukuze ukumelana kuncitshiswe ngokukhawuleza. Ukongeza, ukwehla kokumelana nokuthintela ubushushu kunxulumene ngokuthe ngqo nokungcola kumphezulu. Kwangaxeshanye, uhlalutyo lwedatha yophando lubonisa ukuba utshintsho lobushushu luya kukhokelela ekutshintsheni komlinganiselo wokuthintela ubushushu we-transformer. Kule meko, inokwahlulwa ibe ziimeko ezimbini. Kwi-Lu yoxinzelelo oluguquguqukayo olomileyo, umlinganiselo wokuthintela ubushushu uya kwanda ngokunyuka kobushushu. Nangona kunjalo, xa ubushushu bunyuka bufikelela ngaphezulu kwama-40 ℃, umlinganiselo wokuthintela uyancipha. Kwezinye iimeko, ngokunyuka kobushushu, umlinganiselo wokuthintela uyancipha.

impembelelo yesantya sokunyuka koxinzelelo

Kuvavanyo lwe-high-voltage, isantya sokunyusa siya kuchaphazela ukuvuza kwangoku, ngoko ke kuvavanyo, kuyimfuneko ukubamba ngokuguquguquka ngokwesakhono se-transformer ukulawula ukwenzeka kwempazamo kangangoko kunokwenzeka, ukuze kuqinisekiswe ukuchaneka kweziphumo zovavanyo lwe-high-voltage.

Umzekelo wovavanyo lwe-power transformer

Ukuthatha uvavanyo lokuxhathisa lwe-DC lokujika kunye nokubopha njengomzekelo, imiba efuna ingqalelo kuvavanyo ichazwe ngokufutshane. Ngenxa yokuba ukujika kwe-transformer kune-inductance enkulu kunye ne-inductance efanayo, kodwa inokumelana okuncinci, ngokutsho kwe-time constant yi-L / R, kuya kufunyaniswa ukuba i-time constant inkulu kakhulu. Kwimeko enjalo, ukuba umbane uza kuzinza, ixesha lokutshaja liza kuba lide kakhulu. Ke ngoko, kwezinye ii-transformers ezinkulu, ixesha lovavanyo kufuneka lifinyezwe kangangoko kunokwenzeka. Ukuba kujongwa ukuxhathisa kwi-low-voltage winding ye-transformer enkulu, ekubeni kukho ukujika okumbalwa okunomdla kwi-low-voltage end, indlela ye-series winding magnetization inokusetyenziswa kwaye kufuneka kukhethwe imo yoqhagamshelo echanekileyo.
