Causes of Sudden Short Circuit of Transformer

To deal with transformer short circuit accident in daily operation, it is necessary to find out the essence of the problem through inspection and test. When the transformer suffers from sudden short circuit, the high and low voltage sides will be subject to large short circuit current. In the short time when the circuit breaker has no time to disconnect, the electric force generated by the short circuit current, which is proportional to the square of the current, will act on the transformer winding. This electric force can be divided into radial force and axial force. In case of short circuit, the radial force acting on the winding will make the HV winding subject to tension and the LV winding subject to pressure. Since the winding is circular, the circular object is more easily deformed under pressure than under tension, so the low-voltage winding is more easily deformed. The axial force generated in case of sudden short circuit compresses the winding and causes axial displacement of high and low voltage windings. The axial force also acts on the iron core and clamps. Therefore, when the transformer suffers from sudden short circuit, the low-voltage winding and balance winding are most likely to be deformed, followed by the high-voltage winding, iron core and clamp. In addition to checking the main windings, iron cores, clamps and other parts after the transformer short-circuit accident, a series of related problems should also be paid attention to during the handling process:

Analysis of Transformer Protection in Relay Protection

The transformer is a static device in continuous operation, which is relatively reliable in operation and has less chance of failure. However, since most of the transformers are installed outdoors, and are affected by the load during operation and the short-circuit fault of the power system, various faults and abnormal situations inevitably occur during operation.
