Unokukhetha njani i-thyristor kwiziko lokunyibilikisa induction?

Kwinkqubo yoyilo lwamandla e ukuchithwa kwesithando somlilo, indlela yokukhetha i-inverter thyristor efanelekileyo ngokwesicelo sangempela inokulandela le migaqo ilandelayo:

1. Khetha ixesha lokuphumla ngokuhambelana nokusebenza rhoqo kobonelelo lwamandla ombane wokunyibilika kwesithando somlilo:

a) KK-uhlobo lwe-thyristor kunye nexesha elikhethiweyo le-20µs-45µs kwi-frequency ye-100HZ-500HZ.

b) I-thyristor yohlobo lwe-KK kunye nexesha elikhethiweyo le-18µs-25µs kwi-frequency ye-500HZ-1000HZ.

c) I-thyristor yohlobo lwe-KK ene-frequency ye-1000HZ-2500HZ kunye nexesha elikhethiweyo elikhethiweyo le-12µs-18µs.

d) KKG chwetheza i-thyristor enexesha elikhethiweyo elingekhoyo le-10µs-14µs ngamaxesha amaninzi 2500Hz—4000Hz.

e) I-KA-uhlobo lwe-thyristor kunye ne-frequency ye-4000HZ-8000HZ kunye nexesha elikhethiweyo lokucima i-6µs-9µs.

2. Khetha i-voltage yokumelana kunye nereyithingi yangoku ngokuhambelana nemveliso yamandla yesithando somlilo sokunyibilikisa:

Ngokutsho calculation theory of the parallel bridge inverter circuit of the induction melting furnace, ikhoyo ngoku equkuqelayo nganye induction ukunyibilika thyristor 0.455 amaxesha iyonke langoku. Ukuqwalasela ukuba kukho umda owaneleyo, ubungakanani obufanayo nomgangatho olinganisiweyo ngokuqhelekileyo ukhethwa. thyristor.

a) I-thyristor ene-current ekhethiweyo ye-300A/1400V enegunya le-50KW—-100KW. (380V amandla ombane angaphambili)

b) I-SCR ene-current ekhethiweyo ye-500A/1400V enamandla angama-100KW—250KW. (380V amandla ombane angaphambili)

c) I-SCR ene-current ekhethiweyo ye-800A/1600V enamandla angama-350KW–400KW. (380V amandla ombane angaphambili)

d) I-SCR ene-current ekhethiweyo ye-1500A/1600V enamandla angama-500KW–750KW. (380V amandla ombane angaphambili)

e) I-SCR ene-current ekhethiweyo ye-1500A/2500V enegunya le-800KW-1000KW. (660V amandla ombane angaphambili)

f) I-SCR ene-current ekhethiweyo ye-2000A/2500V enamandla e-1200KW-1600KW. (660V amandla ombane angaphambili)

g) I-SCR ye-2500A/3000V ekhethiweyo yangoku ngamandla e-1800KW-2500KW. (1250V isigaba sombane)
