It repeats no more.
It should be noted that embodiment 1 arrives the method based on three-phase framework that embodiment 3 proposes, being applied not only to discovery has
The three-phase reactor of defect, moreover it is possible to the technique for promoting live three phase arrangement, loosening, matched load value including connector etc.,
When testing at the scene, the adjacent appendages of three-phase reactor can be impacted three-phase matching degree, if three-phase matching degree
Difference, even if impedance value and power factor are being satisfied with range, it is additional that the later period may be because that three-phase imbalance causes a certain phase to obtain
Fever increment, cause to damage.
In addition, three phase frequency changing power has a frequency conversion function, in practical application, impact influences in order to prevent, can assess
Whether characteristic of the three-phase reactor under high-frequency current effect be consistent, can will test frequency raising here, observes corresponding ginseng
Number variation.And three-phase collector can realize that Full wave shape acquires, therefore can be to high-frequency current and/or high frequency voltage testing conditions
The signal of lower acquisition carries out frequency-domain transform, such as small echo or FFT Fourier analysis frequency spectrum analysis method.
