Description

Technical Field

[0001] This utility model relates to the field of magnetic shielding assembly structure technology, specifically a magnetic shielding assembly structure for transformer clamps. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are: an iron core (serving as the medium for electromagnetic induction, guiding changes in magnetic flux) and a coil (divided into a primary coil and a secondary coil; the primary coil is connected to a power source, and the secondary coil generates an induced voltage). When an alternating current flows through the primary coil, an alternating magnetic flux is generated in the iron core, inducing a voltage (or current) in the secondary coil. The magnitude of the induced voltage is proportional to the number of turns in the winding and the maximum value of the main magnetic flux; therefore, the voltage level can be changed by adjusting the number of turns. Traditional grounding wire designs fail to adequately consider the electric field distribution, increasing the risk of partial discharge and potentially posing a threat to the safe operation of equipment. Utility Model Content

[0024] It should be noted that in this embodiment, by stacking magnetic shielding components 5 that fit the iron core 14 on the inner side of the U-shaped shielding frame 1, the side limiting strips 6 on both sides of the magnetic shielding component 5 enter the inner limiting groove 9 on the inner side of the U-shaped shielding frame 1. At this time, the first through hole 7, the second through hole 8, and the third through hole 15 in the magnetic shielding component 5 are in the same position.
