Where are the parts that are easily damaged by induction heating equipment?
1. Thyristor: The short circuit of the thyristor is a good device to check, but be careful of the soft breakdown of the thyristor, which cannot be measured in the circuit. The general phenomenon of soft breakdown of thyristor is that the reactor has a very heavy noise.
2. Capacitor: The short-circuit terminal of the capacitor is generally interrupted. I have also tried to repair the capacitor and found that the repaired capacitor will be broken after a long time. The inspection of the capacitor boost will be easier to see.
3. Water cable: The failure rate of water cable of electric heating equipment is open circuit, and it is easier to be ignored when it seems to be disconnected. Of course, judging by the sound of the intermediate frequency heating electric furnace is an indispensable skill in the maintenance of induction heating equipment! Listen to the sound to judge that the sound of the reactor is heavy and generally rectified, and the sound is screaming generally reversed. When you see the phenomenon, you must ask the customer clearly when It is best to know the situation at that time.
