The application of the transformer skeleton is extremely extensive. Transformers are used in almost all electronic products. The principle is simple, but depending on the application (different applications), the winding process of the transformer will have different requirements.

How to deal with the transformer skeleton short circuit accident. What should be the first thing to think about when encountering a problem. First, the inspection and test of the transformer accessory after a short circuit accident.

When the transformer skeleton is subjected to a sudden short circuit, the most likely deformation is the low voltage winding and the balanced winding, followed by the high and medium voltage windings, the iron core and the clamp. Therefore, the inspection after the short circuit accident of the transformer skeleton is mainly to check the windings, the iron core, the clamps and other parts.

First, the winding inspection and test

When the transformer skeleton is short-circuited, under the action of electrodynamic force, the winding is subjected to various forces such as pressing, pulling and bending at the same time, and the fault caused by the fault is strong, and it is not easy to check and repair, so the focus should be focused after the short-circuit fault Check the winding condition.

Second, the iron core and the clamp inspection.

The core of the transformer frame should have sufficient mechanical strength. The mechanical strength of the core is ensured by the strength of all the clamping members on the core and its connections. When the winding generates electric power, the axial force of the winding will be offset by the reaction force of the clamp. If the strength of the clamp and the pull plate is less than the axial force, the clamp, the pull plate and the winding will be damaged. Therefore, the condition of the core, clamps, pull plates and their connectors should be carefully checked.

The transformer skeleton is a device that converts alternating voltage, current and impedance. When an alternating current is passed through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core) to induce a voltage (or current) in the secondary coil.

The basic principle of the transformer skeleton is the principle of electromagnetic induction. Transformer skeleton--An electrical appliance that uses the principle of electromagnetic induction to transfer electrical energy or transmit signals from one circuit to another is an important component of electrical energy transfer or transmission.
