    After the start of the intermediate frequency furnace, when the power rises to a certain value, the maintenance of the overcurrent protection action of the intermediate frequency furnace

    Fault analysis and processing: This fault phenomenon is generally caused by the following two reasons:

     

        1) The intermediate frequency furnace inverter thyristor water-cooled jacket has a reduced water or heat dissipation effect - replace the water-cooled jacket. Sometimes it is sufficient to observe the water output and pressure of the water jacket, but often due to water quality problems, a layer of scale is attached to the wall of the water jacket, because the scale is an object with poor thermal conductivity, although there is enough water flow. However, because the segregation of scale is greatly reduced in its heat dissipation effect. The method of judging is: running the power at a power lower than the overcurrent value for about ten minutes, stopping quickly, and quickly touching the core of the thyristor element by hand after stopping, if the hand feels hot, the fault is caused by Caused by this.

     

        2) The connection wires of the intermediate frequency furnace channel have poor contact and disconnection - check the connection of the channel, and handle it according to the actual situation. When the connecting line of the tank circuit has poor contact or disconnection, the fire will rise after a certain value rises, which will affect the normal operation of the intermediate frequency furnace, thus causing the protection of the intermediate frequency furnace. Sometimes a transient overvoltage will occur across the thyristor due to a fire. If the overvoltage protection action is too late, the thyristor component will burn out. This phenomenon often occurs when overvoltage and overcurrent occur simultaneously.
