Analysis of six reasons that the equipment of the intermediate frequency induction heating furnace works normally but the power is not up: The equipment works normally, which can only indicate that the equipment parts are intact. If the power does not go up, it means that the parameters of the device are not adjusted properly. The main reasons that affect the power of the device are:

1. The rectifier part is not adjusted properly, the rectifier tube is not completely turned on, and the DC voltage does not reach the rated value, which affects the power output;

2. The IF voltage value is adjusted too high or too low, which affects the power output;

3. Improper adjustment of cut-off and cut-off values makes the power output low;

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

5. If the compensation capacitor is configured too much or too little, the best power output of electric and thermal efficiency will not be obtained, that is, the best economic power output will not be obtained;

6. The distributed inductance of the intermediate frequency output circuit and the additional inductance of the resonance circuit are too large, which also affects the maximum power output;
