How to choose the transformer of the induction melting furnace?
The induction melting furnace transformer is an important part of the induction melting furnace. The suitable induction melting furnace transformer can be used to improve the working efficiency. If the induction melting furnace transformer is not suitable, the induction melting furnace may not work well or even process, so now A suitable induction melting furnace transformer is very important.
There are some points to note when choosing an induction melting furnace transformer.
1, group
2, the impedance voltage
3, the primary voltage
4, the secondary voltage
5, transformer with
6, capacity
7. The isolation barrier layer should be placed between the concave-convex windings and the grounding should be taken out to reduce the harmonic effect caused by the secondary side rectification, and also reduce the magnetic density and temperature rise of the transformer core, that is, the core and the copper wire are larger than the common transformer, and the short circuit The impedance is also about 30% higher than the short-circuit impedance of a conventional transformer.
Note that the output characteristics of the induction melting furnace should be as consistent as possible. If the output voltage is consistent, the leakage resistance is consistent, and the short-circuit impedance is consistent, otherwise serious circulation will occur. If one of the above indicators is inconsistent, it will affect the normal operation of the induction melting furnace. Reduce the work efficiency, and the heavy ones can not work, so when choosing the induction melting furnace transformer, it is necessary to pay special attention to whether the indicators are consistent.
