Causes and treatment methods of overcurrent of high-frequency heating equipment

The reasons for the overcurrent of high-frequency heating equipment are:

The shape and size of the self-made induction coil is incorrect, the distance between the workpiece and the induction coil is too small, there is a short-circuit ignition phenomenon between the workpiece and the induction coil or the induction coil itself, and the prepared induction coil is affected by the customer’s metal fixture or nearby. Metal effects, etc.

Approach:

1. Remake the induction coil. The coupling gap between the induction coil and the heating part is preferably 1-3mm (when the heating area is small).

2. Check whether the heating power matches the protector. If the matching is correct, check whether the operation is correct, mainly the heating time;

3. When induction heating of materials with poor magnetic permeability such as copper and aluminum, the number of induction coils should be increased;

4. The equipment should be protected from sunlight, rain, humidity, etc.;

5. Change the protector switch to a larger one, provided that the heating system is normal.
