Failure Analysis of High Frequency Quenching Machine Tool

Common fault analysis and elimination of primary and secondary short circuits of high frequency quenching machine tool transformers:

(1) Cause analysis of high frequency quenching machine tools

and inductive load circuits. When such a fault occurs, there is a fire between the primary and secondary of the transformer, and in severe cases, water leakage occurs in the primary or secondary. Since the short-circuit points appear in different parts of the primary and secondary, once the main contactor is turned on, the generator working curve may appear in different inductive curve positions, so the response of the instrument is different, but basically G is greatly reduced, /> Cos Xu is perceptual, falling, and both 1GL and 1GJ2 act.

(2) Fault diagnosis of high frequency quenching machine tools

The primary or secondary water supply of the transformer is not smooth or blocked, which causes the winding to heat up, the primary insulation breaks down, and the primary and secondary short circuits are formed.

This kind of fault is easy to find from the scorched winding or the leaking point, and then it can be judged by measuring the electric resistance of the light or the multimeter.
