Kedu otu esi ahọrọ thyristor maka ọkụ ọkụ induction?
Kedu otu esi ahọrọ thyristor maka ọkụ ọkụ induction?
Na ike imewe usoro nke ọkụ na-agbaze ọkụ, otu esi ahọrọ thyristor inverter kwesịrị ekwesị dị ka ngwa ngwa nwere ike ịgbaso ụkpụrụ ndị a:
1. Họrọ oge nkwụsị dị ka oge ọrụ nke ọkụ ọkụ induction na-agbaze ọkụ si dị:
a) Ụdị thyristor nke KK nwere oge ahọrọ nke 20µs-45µs na ugboro nke 100HZ-500HZ.
b) Ụdị thyristor nke KK nwere oge ahọrọ nke 18µs-25µs na ugboro nke 500HZ-1000HZ.
c) KK-ụdị thyristor nwere ugboro nke 1000HZ-2500HZ na oge ahọrọ nke 12µs-18µs.
d) Ụdị thyristor KKG nwere oge ahọrọ nke 10µs-14µs na ugboro 2500Hz-4000Hz.
e) KA-ụdị thyristor nwere ugboro nke 4000HZ-8000HZ yana oge ngbanwe ahọpụtara nke 6µs-9µs.
2. Họrọ voltaji na-eguzogide na akara ugbu a dị ka mmepụta ike nke ọkụ ọkụ induction:
Dabere na ngụkọ usoro nke parallel bridge inverter circuit nke induction na-agbaze ọkụ, nke ugbu a na-erute n’ime ọkụ ọ bụla induction na-agbaze thyristor bụ 0.455 ugboro ngụkọta ugbu a. N’iburu n’uche na oke oke zuru oke, a na-ahọrọkarị otu nha dị ka ọnụọgụ ugbu a. thyristor.
a) Thyristor nwere 300A/1400V ahọpụtara nke nwere ike nke 50KW—-100KW. voltaji na-aga n’ihu (380V)
b) SCR nwere 500A/1400V ahọpụtara nke nwere ike nke 100KW-250KW. voltaji na-aga n’ihu (380V)
c) SCR nwere 800A/1600V ahọpụtara nke nwere ike nke 350KW–400KW. voltaji na-aga n’ihu (380V)
d) SCR nwere 1500A/1600V ahọpụtara nke nwere ike nke 500KW–750KW. voltaji na-aga n’ihu (380V)
e) SCR nwere 1500A/2500V ahọpụtara nke nwere ike nke 800KW-1000KW. voltaji na-aga n’ihu (660V)
f) SCR nwere 2000A/2500V ahọpụtara nke nwere ike nke 1200KW-1600KW. voltaji na-aga n’ihu (660V)
g) SCR nke 2500A/3000V ahọpụtara ugbu a nwere ike nke 1800KW-2500KW. (1250V voltaji na-agba ọsọ)
