The main function of the shielding cover.

The primary function of the Shielding Cover is to block external electromagnetic waves from affecting the internal circuits and to prevent the internally generated electromagnetic waves from radiating outward. This protects Electronic Equipment from interference and prevents its electromagnetic radiation from impacting the surrounding environment. Specifically, the functions of the shielding cover include:

1. Preventing External Electromagnetic Interference: The shielding cover can block external electromagnetic waves from entering the electronic equipment, protecting the equipment from external interference and ensuring its normal operation.

2. Preventing Internal Electromagnetic Radiation: The shielding cover also prevents the electromagnetic waves generated inside the electronic equipment from radiating outward, reducing electromagnetic pollution in the surrounding environment.

3. Improving Electric Field Distribution: In certain applications, such as vacuum arc chambers, the shielding cover can improve the uniformity of the electric field distribution, reduce local field intensity, and enhance the performance of the equipment.

4. Condensing Arc Products: The shielding cover can condense arc products and absorb part of the arc energy, aiding in the recovery of the dielectric strength of the post-arc gap.

5. Heat Dissipation and Increasing Strength: The shielding cover also has functions of heat dissipation and enhancing the strength of the equipment, helping the equipment better withstand high temperatures and mechanical stress.
