Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.
[0027] like figure 1 As shown, a new type of electromagnetic shielding structure under the strong electromagnetic environment of a giant hydroelectric generator is characterized in that it includes a multi-layer silicon steel sheet 2 and a layer of aluminum plate 1 that are stacked and laminated in parallel; the multi-layer silicon steel sheet 2 and a layer The aluminum plates 1 are sequentially stacked and fixedly connected to form an integrated shielding structure; a plurality of channel steels 3 are evenly arranged on the surface of the machine pit wall opposite to the copper bar 9, and the shielding structure is arranged parallel to the machine pit wall and fixedly connected to the channel steel 3; The silicon steel sheet 2 is...
