How are the power supply primary and secondary respectively????? And how to determine whether the fault is primary or secondary?!!!
This is a transformer, general primary only one winding, its line diameter is small (fine), the resistance is big, bear the voltage high level, the diameter of the line is coarse, the resistance is small, the withstanding voltage is small, and sometimes there are many windings
In general when Caifen power transformer primary and secondary side, external input for the primary electricity is very time. As for the fault diagnosis is too complex, a few words unclear
Normally, the high voltage at both ends of the transformer is low, and one end of the transformer is judged by secondary faults. You can use a multimeter to measure whether the primary resistance is normal
How are the power separately primary and secondary, and how to determine the fault in the primary or secondary? 1, if there is a group of output, then, from the surface, the transformer is generally only two lines of primary, secondary to three lines above. But there are signs in general. 2, from the inside, the primary circle more, line diameter fine. Secondary ring number is small, diameter is coarse. 3 、 by measuring method, the primary resistance is large, the secondary resistance is small, the primary voltage is high, and the secondary voltage is low.
