Siffofin zaɓi na Thyristor don 1000kw induction narkewa tanderu

Matsalolin zaɓi na Thyristor na 1000kw injin wutar lantarki

Wutar lantarki mai shigowa da aka ƙera shine 380V, kuma ana iya samun waɗannan bayanan ta hanyar ƙididdigewa:

DC ƙarfin lantarki Ud=1.35×380V=510V

DC na yanzu Id=1000000÷510=1960A

Matsakaicin mitar ƙarfin lantarki Us = 1.5 × Ud = 765V

rated silicon rectifier na yanzu IKP=0.38×Id=745A

rated silicon rectifier ƙarfin lantarki UV=1.414×UL=1.414×510V=721V

Inverter silicon rated halin yanzu Ikk=0.45×19600=882A

Inverter silicon rated irin ƙarfin lantarki UV = 1.414 × Us = 1082V

Tsarin zaɓin ƙirar SCR: zaɓi Xiangfan Taiji SCR:

Saboda yana ɗaukar kayan aikin gyara guda 6-pulse guda ɗaya, mai gyara SCR ya zaɓi KP2000A/1400V (jimlar 6), wato ƙimar halin yanzu shine 2000A kuma ƙimar ƙarfin lantarki shine 1400V. Idan aka kwatanta da ƙimar ka’idar, ƙimar ƙarfin lantarki shine sau 1.94 kuma gefe na yanzu shine sau 2.68.

The inverter thyristor ya zaɓi KK2500A/1600V (hudu a jimlace), wato rating halin yanzu 2500A, kuma rated ƙarfin lantarki ne 1600V. Idan aka kwatanta da ƙimar ka’idar, ƙimar ƙarfin lantarki shine sau 1.48, kuma gefen yanzu shine sau 2.83.
