On the Application Range of Transformer Skeleton
Transformer skeleton applications are extremely extensive. Transformers are used in almost all electronic products, and the principle is simple but different depending on the use of different occasions (different purposes) transformer winding process will be different requirements.
Transformer skeleton short circuit accident how to deal with. What should be the first thing to think about? First, the transformer parts after a short circuit accident check, test.
Transformer skeleton in the sudden short circuit, the most prone to deformation of the low-voltage winding and the balance winding, and then high and medium voltage winding, core and clip pieces. Therefore, the transformer skeleton short circuit after the inspection is mainly to check the winding, iron, clip and other parts.
First, the winding inspection and testing
As the transformer skeleton short circuit, under the action of electric power, the winding at the same time by the pressure, pull, bending and other forces, the resulting fault concealment is strong, it is not easy to check and repair, so short-circuit fault should focus Check winding conditions.
Second, the core and folder pieces of inspection.
The core of the transformer skeleton shall have sufficient mechanical strength. The mechanical strength of the core is ensured by the strength of all clamping parts on the core and its connections. When the winding generates electromotive force, the axial force of the winding will be counteracted by the reaction force of the clamp. If the strength of the plate is less than the axial force, the clamp, pull plate and winding will be damaged. Therefore, the core, clip, pull plate and its connection should be carefully checked.
Transformer frame is to change the AC voltage, current and impedance of the device, when the primary coil with AC current, the core (or core) will produce AC flux, the secondary coil induced voltage (or current).
The basic principle of transformer skeleton is the principle of electromagnetic induction. Transformer skeleton - the use of electromagnetic induction principle, from one circuit to another circuit to transfer electricity or transmission of an electrical signal is the power transmission or as an important component of signal transmission.
