Intermediate Frequency Induction Furnace with Dual Power Supplying System

The dual power supply method can not only enable the full function of the "one drag and two electric furnaces" in the intermediate frequency induction furnace, but also the other power supply can also be operated when one power fails, thereby avoiding affecting production. The two furnaces in each set of electric furnaces in the entire system can work at the same time. At the time of work, one furnace body is melted, and the other furnace body is heating, insulation, and regulating.

The two sets of independent intermediate frequency power supply in this set of electric furnaces have no adjustable power, and the power adjustment range is: 10 to 100%. It is mainly to use households to improve productivity and meet different production technology needs. You can accurately adjust the temperature and warm heating section. The two furnaces can be preheated and sintered furnaces at the same time. Also, one is for melting and another for insulation. This can maximize production efficiency and reduce melting costs.

Set on-site operation cabinets on the electric furnace platform. Control the operation, stop, and power output adjustment of the two sets of power supply respectively. The output power adjustment can be controlled manually or automatically. The operating cabinet can install a computer, display, and instrument to display the running status and failure of the power supply, and control the two stoves in the two intermediate frequency power supply to work alone or at the same time. It can meet the requirements of a furnace body to mild a furnace body, and the two furnaces are heating up at the same time. When a stove fails, it is necessary to repair it, and the other stove can work normally.

The computer system has melting monitoring, setting alarm, and data acquisition display. The system continuously monitor and display various main parameters; it can automatically diagnose and display the system failure, and can also remember the source of the trip; you can monitor the inlet voltage at any time; display: Power supply status, power consumption (KW.H), voltage, current, power, power, stove voltage, current, working frequency and other parameters, and fault diagnosis status.

Power distribution and restrictions: turn on the automatic control system of the power supply. The two power supply can freely switch the working status (melting/insulation), and ensure that the total power of the two power supply does not exceed the limited value.

Isolation device: When a stove fails, it needs to be maintained, the isolation device can disconnect the two control systems, and the other stove can work normally.
