dv kev / ua dt yog tus nqi them ntawm qhov hluav taws xob hauv SCR. Lawv txuas nrog hla lub thyristor kom tiv thaiv. Thecapacitor 'C' yog siv los txwv cov dv kev / ua dt ntawm SCR. Lub resistor 'R' yog siv los txwv kev tso tawm siab dhau los ntawm SCR. Thaum hloov S raug kaw, lub capacitor 'C' behavesas luv-circuit.
Raws li, lub hom phiaj ntawm Di DT tiv thaiv yog dab tsi?
di / dt kev tiv thaiv yog yuav tsum tau tiv thaiv thyristor los yog SCR los ntawm kev tsim ntawm lub zos hotspot vim tus nqi siab ntawm tus nqi ntawm kev hloov ntawm anode tam sim no i.e. di / ua dt nyob ze ntawm lub rooj vag mus rau cathode hlws ris thaum nws tig rau txheej txheem.
Ib yam li ntawd, kev tiv thaiv thyristor yog dab tsi? A thyristor yog ib qho khoom siv hauv lub xeev siv los hloov thiab tswj cov hluav taws xob tam sim no. Vim tus yam ntxwv no thiab dav kev tiv thaiv rating ntau, thyristors yog siv raws li cov tswj tam sim no. Tiv thaivthyristors yog siv rau overvoltage kev tiv thaiv.
Piv txwv li, DV dt thiab di DT yog dab tsi?
di / ua dt yog tus nqi hloov ntawm tam sim no thiab dv kev / ua dt yog tus nqi hloov ntawm voltage.
Dab tsi yog qhov kev ntsuas ntawm SCR?
Qhov siab tshaj tus nqi ntawm anode tam sim no, uas ib SCR tuaj yeem ua tau zoo (tsis muaj kev puas tsuaj), yog hu ua forwardcurrent kev ntaus nqi . Tam sim no ib txwm kev ntsuam xyuas ntawm SCRs yog los ntawm 30 A mus rau 100 A. Yog hais tias qhov tam sim no tshaj lub forwardcurrent kev ntaus nqi , cov SCR tuaj yeem raug puas vim yog cua sov ntawm cov junctions.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Dab tsi yog atoms tsis yog thaum muaj tshuaj tiv thaiv?
Atoms tsis yog CREATED lossis DESTROYED thaum muaj tshuaj tiv thaiv. Cov kws tshawb fawb paub tias yuav tsum muaj tib tus lej ntawm atoms ntawm txhua SIDE ntawm EQUATION. Txhawm rau sib npaug ntawm cov tshuaj sib npaug, koj yuav tsum ntxiv COEFFICIENTS nyob rau hauv pem hauv ntej ntawm cov qauv tshuaj hauv qhov sib npaug. Koj tsis tuaj yeem ntxiv lossis hloov cov ntawv sau npe
Puas yog dej tiv thaiv tsis muaj zog tiv thaiv?
Kev sib txhuam yog lub zog tshwm sim los ntawm ob yam khoom sib tsoo ua ke. Huab cua tsis kam thiab dej tsis kam yog hom kev sib txhuam. Lawv hu ua non- contact rog
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
