Causes and treatment methods of overcurrent when բարձր հաճախականության ջեռուցման սարքավորումներ միացված է

Reasons for overcurrent at startup:

1. IGBT breakdown.

2. Տախտակը անսարք է:

3. Caused by the balance of the small magnetic ring.

4. The circuit board is wet.

5. The power supply of the driver board is abnormal.

6. The sensor is short-circuited.

The processing method of overcurrent at startup:

1. Replace the drive board and IGBT, remove the small magnetic ring from the lead, check the waterway and whether the water box is blocked, blow the used board with a hair dryer, and measure the voltage;

2. Overcurrent after using for a period of time after booting: The reason is generally poor heat dissipation of the driver. Treatment method: Reapply silicone grease; check whether the waterway is blocked.
