First, the configuration method of the intermediate frequency power supply cabinet:
1, rated phase voltage: 380V, medium frequency output voltage 900V, DC current: 1200A, power: 600KW
2, KK thyristor 1000A/1600V 8
3, KP thyristor 100A/1600V 6
4, air switch 1600A
5, installed copper row 60 mm X 6 mm
6, reactor (copper tube diameter 14mm, wall thickness 1.5mm coil, 8)
6, intelligent system
Second, the capacitor cabinet:
Capacitor 2000KF / 750V 4 sets 360KF/750V 1 set
Induction melting furnace
Reducer: 431
Furnace shell: diameter 1130 mm high 1280 mm.
Induction ring: Copper tube 25 mm X 35 mm X 3.5 mm Inner diameter 630 mm 18 turns.
Features:
1. Intelligent system, fast protection, durable thyristor, good starting performance, stable operation and convenient operation.
2, using large copper discharge machine, saving electricity; using the booster circuit, the voltage across the furnace can reach 1800V (two times the output voltage of the electric cabinet), the water cable, the induction loop loss is small, and the power is saved.
