Method for comparing and detecting induction melting furnace

The contrast method is a method of finding the cause of the fault by comparing the normal feature with the wrong feature. When there is a problem in a certain unit circuit of the induction melting furnace, the parameters of the unit circuit can be the same as those of the normal unit circuit in the working state. (For example, theoretical analysis of current, voltage, waveform, etc.) for a comparison. This method is most suitable when there is no circuit schematic diagram, that is, the fault is judged by comparing the test data with the drawing data and the normal parameters recorded normally. The induction melting furnace with no data and no usual recording can be melted with the same type of intact induction. Comparing the furnaces, finding out the abnormal conditions in the unit circuit, analyzing the cause of the fault, and judging the fault point, the comparison method can be an analogy of the same unit circuit itself, or a comparison between the fault circuit board and the known circuit board. This can help maintenance personnel quickly narrow down the scope of the fault check.
