Nzira yekusarudza thyristor kune induction yakanyungudika choto?
Nzira yekusarudza thyristor kune induction yakanyungudika choto?
Mune simba rekugadzira maitiro e kudonhedzwa kunyorera vira, nzira yekusarudza yakakodzera inverter thyristor zvinoenderana neiyo chaiyo application inogona kutevedzera zvinotevera misimboti:
1. Sarudza nguva yekuvharwa zvichienderana nekushanda frequency ye induction yekunyungudutsa muchoto simba rekupa:
a) KK-mhando thyristor ine yakasarudzwa off-nguva ye20µs-45µs pafrequency ye 100HZ-500HZ.
b) KK-type thyristor ine yakasarudzwa off-time ye18µs-25µs pafrequency ye500HZ-1000HZ.
c) KK-type thyristor ine frequency ye1000HZ-2500HZ uye yakasarudzwa-nguva ye12µs-18µs.
d) KKG mhando thyristor ine yakasarudzwa off-nguva ye10µs-14µs pafrequency 2500Hz-4000Hz.
e) KA-type thyristor ine frequency ye4000HZ-8000HZ uye yakasarudzwa yekudzima nguva ye6µs-9µs.
2. Sarudza inomira voltage uye yakayerwa ikozvino zvichienderana nekubuda kwesimba kweiyo induction inonyungudika choto:
Zvinoenderana ne theoretical calculation ye parallel bridge inverter circuit ye induction melting furnace, iyo yazvino inoyerera kuburikidza neimwe induction inonyungudutsa furnace thyristor ndeye 0.455 nguva iyo yakazara ikozvino. Tichifunga kuti kune muganhu wakakwana, saizi yakafanana neyeyero yakayerwa ikozvino inowanzosarudzwa. thyristor.
a) Thyristor ine yakasarudzwa ikozvino ye300A/1400V ine simba re50KW—-100KW. (380V yepamberi voltage)
b) SCR ine yakasarudzwa parizvino ye500A/1400V ine simba re100KW—250KW. (380V yepamberi voltage)
c) SCR ine yakasarudzwa ikozvino ye800A/1600V ine simba re350KW–400KW. (380V yepamberi voltage)
d) SCR ine yakasarudzwa ikozvino ye1500A/1600V ine simba re500KW-750KW. (380V yepamberi voltage)
e) SCR ine yakasarudzwa ikozvino ye1500A/2500V ine simba re800KW-1000KW. (660V yepamberi voltage)
f) SCR ine yakasarudzwa ikozvino ye2000A/2500V ine simba re1200KW-1600KW. (660V yepamberi voltage)
g) SCR yeazvino yakasarudzwa 2500A/3000V ine simba re1800KW-2500KW. (1250V chikamu-in voltage)
