    Required protection for the 1.5 ton melting furnace control circuit

    1 , 1.5 ton melting furnace rectification trigger system. It is used to control the thyristor of the rectifier bridge, and can adjust the output voltage of the rectifier bridge to adjust the output power of the intermediate frequency. In the shutdown or fault state, it can also make the rectifier bridge into the inverter state, and feedback the stored energy in the filter reactance back to the grid to avoid overvoltage generated in the filter reactance Ld and stop the intermediate frequency device from working.

    2. 1.5 ton melting furnace inverter trigger system to control the normal operation of the inverter

    3. The composition of the protective circuit of the 1.5 ton melting furnace :

    a. Overcurrent protection Mainly used to protect all thyristors in the device to prevent damage during short circuit.

    b. Overvoltage protection Mainly used to protect the thyristor and compensation capacitors in the device from overvoltage breakdown.

    c. Current cut-off and voltage cut-off link When the IF load changes drastically, it is used to limit the load current and voltage within the allowable range.
