    Medium frequency melting furnace maintenance classroom IF power overvoltage and overcurrent protection link failure maintenance.

     

    The protection link of the IF power supply is very important. Generally, there are over voltage, over current protection, cutoff, shutoff, overload protection and fast fuse short circuit protection. These three "defense lines" can protect the general faults.

    If the protection link fails, some components fail, the circuit is soldered, or the setting value is incorrect, the thyristor may be damaged. Therefore, their protective properties should be checked regularly, and ^sickness ̄ work is not allowed.

     The frequency of the intermediate frequency electric furnace does not go wrong: the intermediate frequency melting furnace works normally, but the power is not analyzed and processed: the intermediate frequency melting furnace works normally, and only the components of the intermediate frequency melting furnace can be said to be intact. The power does not indicate that the adjustment of the parameters of the intermediate frequency melting furnace is not suitable, and the main reasons that affect the power of the intermediate frequency melting furnace are:

     

        1. The furnace body and the power supply are not matched, which seriously affects the power output.

     

        2. The rectification part is not adjusted well, the rectifier tube is not fully turned on, and the DC voltage does not reach the rated value, which affects the power output.

     

        3. The distributed inductance of the output circuit of the intermediate frequency melting furnace and the additional inductance of the resonant circuit are too large, which also affects the maximum power output.

      

        4. The voltage value of the intermediate frequency electric furnace is adjusted too high and too low, affecting the power output.

     

        5. The interception and interception values are adjusted improperly, resulting in low power output.

     

        6. If the compensation capacitor is configured too much or too little, the power output with the best electrical efficiency and thermal efficiency will not be obtained, that is, the optimal economic power output will not be obtained.
