Question:

What is the difference between the total switching time and the excessive time in the transformer on-load tap-changer test data?

There are the same period, these three parameters on behalf of what?

Answer:

2, the so-called transition time refers to the transition process in the transition resistance of the input time, from the waveform point of view is the falling section of the waveform (including the middle of the waveform half of the protruding section), and the total switching time also includes the transition time Initial and end of the sliding time.
1, on the on-load tap-changer refers to the same period refers to the same period (different from the same period of multi-fracture), that is, the difference between the maximum and minimum, different brands of tap-changer performance indicators are different, but The same period generally requires a few ms. Part of the on-load tap-changer tester only switch time display, the same period of data need their own calculation.
The total number of a few, that also called what the same period! There are ah! I tell you ha! The nature of the on-load tap-changer and the circuit breaker is almost a switch itself, but there is an over-resistance or an over-device in the same period, the same period refers to the synchronization between the three phases, three different numbers Normal, the key is whether the deviation in line with national norms or industry standards.
The total switching time includes excessive time. Excessive time means that the on-load tap-changer switches from one splitter to another. The splitter has an over-process, similar to the semi-detached state. The total switching time is obviously the total time for all the processes to be completed. The same period refers to the three-phase switch breaking and closing the same period.
