First, the intermediate frequency power supply:
1. Phase-in voltage: 1250V, DC output voltage 1600V, intermediate frequency voltage: 2300V
DC current: 2200A, power: 3500KW
Intelligent control system
2, KK thyristor 1000A / 2500V 24
3, KP SCR 2500A / 3500V 6
4, air switch 4000A
5, installed copper bar 120 mm X 6 mm
Second, the capacitor cabinet:
电容器 Capacitor 4000KF / 2500V 10 sets
Third, the induction melting furnace
1.8 1.85 meters in diameter, 2.1 meters in height, double-layer furnace body, high-strength aluminum alloy on the inner layer, and high-quality stainless steel on the outer layer
2 531A reducers, 4 water cables
Total machine: RMB 360,000 (single furnace); RMB 510,000 (dual furnace)
Features:
1. The phase-in voltage is as high as 1250v, and the DC voltage is high, which significantly reduces the losses of electrical cabinets, transmission lines and power transformers.
2. The intermediate frequency voltage is up to 2300V, and the booster circuit is used. The voltage across the induction furnace is up to 4600V, which greatly reduces the loss of the induction coil and water cable.
3,24 1000A / 2500V KK thyristors, three sets of KK thyristors connected in parallel, low power consumption, and the cost of purchasing KK thyristors during maintenance can be reduced by three times (such as damage to 4 KK2500A / 2500V Silicon needs about 3600 yuan, and three sets of KK thyristors are connected in parallel.On the same condition, only one of them will be damaged. Four KK1000A / 2500V thyristors only need about 1200 yuan, which greatly reduces maintenance costs.) .
4. Increase the induction melting furnace. The new furnace can produce 6.5 tons, and the furnace will be used more later.
5. Intelligent system, fast protection, simple structure, convenient operation and easy maintenance.
