METHOD AND DEVICE FOR AUTOMATICALLY DETECTING THE INTACTNESS OF GROUND ELECTRODES IN THE BATH OF AN INDUCTION FURNACE AND INDUCTION FURNACE |
摘要 |
<p>A method and an apparatus for detecting a ground fault in an induction furnace as well as an induction furnace are described. When a ground fault is detected by means of the ground-fault detector the ground fault is localized. By doing this it is determined if the ground fault is caused by a failure of the refractory lining or by other reasons. If the ground fault is caused by other reasons it is ascertained if it is caused by a defective magnetic yoke insulation. Furthermore, it can be ascertained which magnetic yoke of the induction furnace causes a ground fault. In this manner the induction furnace can be operated with improved security and smaller expense.</p> |
