The role of the shielding layer of a planar transformer is mainly reflected in the following aspects:

1、 Reduce electromagnetic interference

Preventing external electromagnetic interference:

The shielding layer of a planar transformer can effectively prevent external electromagnetic fields from interfering with the internal circuits of the transformer, ensuring stable and accurate transmission of electrical energy.

Reduce internal electromagnetic radiation:

The shielding layer can limit the radiation range of the electromagnetic field inside the transformer, reducing the impact of electromagnetic radiation on surrounding equipment and the environment.

2、 Improve electrical performance

Enhance electromagnetic compatibility:

By setting up a shielding layer, planar transformers can better meet the requirements of electromagnetic compatibility and ensure normal operation in different electromagnetic environments.

Enhance anti-interference ability:

The shielding layer can enhance the resistance of transformers to external interference signals, improve the stability and reliability of transformers.

3、 Protect transformers and their surrounding equipment

Prevent short circuit:

In a vehicle mounted flat transformer, the shielding layer can prevent short circuits between the metal components inside the vehicle and the primary winding, thereby protecting the transformer from damage.

Extend service life:

The shielding layer can reduce the erosion and damage of external factors to the transformer, such as dust, moisture, etc., thereby extending the service life of the transformer.

4、 Enhance security

Reduce the risk of electric shock:

The shielding layer can effectively prevent personnel from directly contacting the live parts of the transformer, reduce the risk of electric shock, and improve the safety of use.

Preventing arc hazards:

In some cases, the shielding layer can also isolate the arc inside the transformer within the shielding layer, avoiding harm to the outside.

In summary, the shielding layer of planar transformers plays an important role in reducing electromagnetic interference, improving electrical performance, protecting transformers and their surrounding equipment, and enhancing safety. Therefore, when designing and manufacturing planar transformers, the design and optimization of the shielding layer should be fully considered to ensure the performance and safety of the transformer.
