Product Description

It is suitable for vacuum consumable furnace, shell furnace and plasma furnace in vacuum metallurgy industry, and is used for smelting rare metals such as tungsten, titanium, zirconium, refractory metals and alloy ingots.It adopts high current and low voltage DC power supply, and takes 6-pulse double reverse star belt balanced reactor line as the basic unit topology. It can form 12-pulse, 24-pulse and other multi-pulse combination structures through transformer phase shifting, which can meet the application needs of different working conditions, effectively reduce harmonic pollution and improve reliability.

Main Parameters

Input Parameters：

          Voltage: AC 3Φ380V, 690V, 6kV, 10kV and other voltage levels

                  Frequency: 50Hz

Output Parameters：

          Voltage: DC30 ~ 85V (customizable)

                 Current: DC6000 ~ 30000A (customizable)

Features：

             The power supply output has high no-load voltage and is easy to start arc

                 The output DC current has a droop characteristic, which allows reliable operation even when the load is frequently short-circuited.

           The power supply has a large current margin and can withstand frequent impact currents. It has protection functions such as overcurrent, insufficient water pressure, fuse blown, transformer oil temperature and gas (oil change)
