What are the manifestations and causes of transformer short circuit

Transformer is a relatively important power equipment. There are many faults caused by transformer. Generally, most of them are caused by transformer short circuit. The problems caused by transformer short circuit should be properly solved, and the ability to solve transformer short circuit should be continuously improved, so that the transformer performance can be continuously improved. The problems that need to be paid attention to when transformers cause faults should be clear about the forms and main causes of transformer faults. The specific manifestations and causes are as follows:

There are many kinds of reasons for transformer short circuit, which are also complex. It is related to the quality of raw materials, process level, operating conditions and other factors. The remarkable feature of short circuit in the process of using ring transformer is that the high coil temperature causes the outer insulating material - polyester film to melt. There are two obvious manifestations:

A: Melting of partially wrapped polyester film;

B: Melting of polyester film;

This may be caused by the following reasons:

1: There is a short circuit fault in the components behind the transformer.

2: Working with rated load for a long time.

3: Voltage fluctuation is too high, resulting in transformer saturation.

4: The enameled wire is scratched or cracked.

5: Metal foreign matters enter during production.

6: Corrosive gas enters the working environment.

7: Hard collision occurs during transportation or use.

8: The winding wire is wrongly connected during use.

9: Insulation system breakdown or aging.

The above are the manifestations of transformer short circuit and the main causes of transformer short circuit. You should make clear the actual ground short circuit of the transformer and then solve it. In this way, the functions and various functions of the transformer will be more reflected.
