In the operation of baoding dry type transformer, some abnormal conditions often occur. In fact, these situations are often caused by short circuits. Today, in order to better solve the problem, shandong tebian power equipment co., LTD.

Baoding dry type transformer failure often because of internal and external two kinds of fault, if the external when subjected to sudden short circuit, the high and low voltage side will be impacted by the short circuit current, the momentary circuit breaker not disconnect before, produce strong electric short-circuit current, the electrical power will Yu Baoding dry type transformer winding.

In case of short circuit, the radial force acting on the winding will make the high voltage winding suffer tension. The axial force acting on the winding will put pressure on the low-voltage winding. As the winding of baoding dry type transformer is round, the round object is easier to deform under pressure than under tension. Therefore, the low-voltage winding is easy to deform. The axial force generated in the sudden short circuit will make the winding compress, and also make the high and low voltage winding axial displacement. In fact, the axial force also ACTS on the core and clamps. From the above summary, it can be seen that when the transformer suffers from sudden short circuit, the low-voltage winding is the most likely to deform, followed by the high-voltage winding, iron core and clamps.

Winding deformation, including the change of axial and radial dimensions, body displacement, winding distortion, drum and inter-turn short circuit, is a hidden danger in the safe operation of power system. After the transformer system is deformed, some of them will be damaged immediately, and most of them can continue to operate for a period of time, the length of which depends on the severity and location of the deformation. Obviously, this kind of transformer is with "ill" operation, with hidden trouble (hidden trouble).

For the power transformer whose windings have been deformed but are still in operation, although it does not mean that the insulation breakdown accident will occur immediately, it is different according to the deformation; When again subjected to a small overcurrent or overvoltage, even under normal operation of ferromagnetic vibration; It may also cause an insulation breakdown accident. Therefore, in some so-called "lightning strike" or "sudden" accident, it is likely to be hidden winding deformation fault factors.

So when the power transformer failure, to timely follow up inspection, troubleshooting, to avoid future safety hazards.
