How can transformer shielding cover effectively suppress electromagnetic field interference?

Time:2024-10-23Number:836

In today's increasingly popular electronic devices, the problem of electromagnetic interference (EMI) has become more prominent, especially the electromagnetic radiation generated by power electronic devices such as transformers during operation. This not only affects the performance of the devices themselves, but may also cause interference to other electronic devices around them, and even pose a potential threat to human health. This article will explore in depthTransformer shielding coverHow to effectively suppress electromagnetic field interference, and cite actual data and cases, especially in combination with the technical practices of Advanced Institute (Shenzhen) Technology Co., Ltd. and Research Platinum brand.

Sources and Effects of Electromagnetic Field Interference

Electromagnetic field interference mainly comes from high-frequency current and voltage changes in electronic devices, which generate electromagnetic waves in space and cause interference to the surrounding environment and other devices. As a key component for power transmission and conversion, transformers inevitably generate electromagnetic radiation during their operation. When these radiations exceed a certain range, they will have adverse effects on surrounding electronic devices, communication systems, etc.屏蔽罩

Design principle of transformer shielding cover

Transformer shielding cover is a specially designed metal or composite material structure aimed at limiting the electromagnetic field generated by the transformer within a certain range and preventing it from leaking into the external environment. The design principles mainly include the following aspects:

  1. Material selection: The ideal shielding material should have good electrical conductivity and magnetic permeability, and be able to effectively absorb and reflect electromagnetic waves. Copper and aluminum are commonly usedShielding materialThey not only have good conductivity, but also relatively low cost. In addition, composite materials such as metal plastic composites and metal fiber reinforced composites are widely used due to their excellent properties.

  2. Structural design: The structural design of the shielding cover needs to ensure a tight fit with the transformer to reduce electromagnetic field leakage. Usually, the shielding cover can be designed to wrap around the entire transformer or only cover critical parts. The internal shielding layer should be tightly attached to the coil, while the external shielding layer should be connected to the transformer casing to form a complete shielding system.

  3. Grounding treatment: Good grounding is the key to the effectiveness of the shielding cover. The shielding cover needs to be closely connected to the reference ground plane of the transformer to ensure that electromagnetic waves can be effectively guided into the ground, thereby avoiding interference with other equipment.

Technical Practice of Advanced Institute (Shenzhen) Technology Co., Ltd

Advanced Institute (Shenzhen) Technology Co., LtdAs an innovative service provider of electromagnetic shielding and thermal conductivity solutions, we have accumulated rich experience in the design and application of transformer shielding covers. The company has launched a series of high-performance shielding materials and solutions through independent research and technological innovation, effectively suppressing electromagnetic field interference from power electronic devices such as transformers.

Data reference comparison

The following is a set of comparative data showing the changes in electromagnetic field intensity before and after using the shielding cover provided by Advanced Institute (Shenzhen) Technology Co., Ltd.:

measurement position Electromagnetic field intensity without using shielding cover (dB μ V/m) Electromagnetic field intensity after using a shielding cover (dB μ V/m) Decrease (%)
1 meter in front of the transformer 85 50 41.2
1 meter on the side of the transformer 70 35 50.0
1 meter behind the transformer 65 30 53.8

From the above data, it can be seen that after using the shielding cover provided by Advanced Institute (Shenzhen) Technology Co., Ltd., the electromagnetic field intensity at various positions around the transformer significantly decreased, with a maximum reduction of 53.8%. This fully demonstrates the effectiveness of the shielding cover in suppressing electromagnetic field interference.屏蔽罩

Application of Research Platinum Brand in Shielding Materials

As a well-known brand under Advanced Institute (Shenzhen) Technology Co., Ltd., Yanbo brand's products also perform well in the field of electromagnetic shielding.Research Platinum Brand Shielding MaterialsNot only does it have good conductivity and film-forming properties, but it also has good temperature stability and process stability. In the design of transformer shielding covers, platinum brand shielding materials are widely used in both internal and external shielding layers, further enhancing the shielding effect.

conclusion

Transformer shielding coverAs an effective means of suppressing electromagnetic field interference, it plays an important role in the design and application of power electronic equipment. By selecting shielding materials reasonably, optimizing structural design, and ensuring good grounding treatment, the electromagnetic radiation generated by transformers can be significantly reduced, ensuring the normal operation of surrounding equipment and human health. Advanced Institute (Shenzhen) Technology Co., Ltd. and its platinum brand products have demonstrated outstanding technical strength and market competitiveness in this field, making important contributions to the development and application of electromagnetic shielding technology.

The above data is for reference only, and specific performance may vary due to production processes and product specifications.联系我们
