Description

Technical Field

[0001] The utility model relates to a shielding component, in particular to a high-voltage shielding cover. Background Art

[0002] High-voltage power transmission is a method of transmitting power by stepping up the voltage output by the generator through a transformer in a power plant. The reason for using this method of power transmission is that under the same transmission power, the higher the voltage, the smaller the current. In this way, high-voltage power transmission can reduce the current during transmission, thereby reducing the heat loss caused by the current and reducing the material cost of long-distance transmission. In DC high-voltage power transmission equipment, shielding covers are often used to protect important components of high-voltage power transmission equipment and can play a role in magnetic shielding. Therefore, their use in high-voltage power transmission equipment is essential.

[0003] In the prior art: CN201420697673.2 A new type of high-voltage resistant shielding cover includes a body and an upper cover. The body is cylindrical, and an upper cover is provided on the body. The upper cover and the body are connected to each other. The middle of the body is a hollow structure. A connecting flange is provided on the body. A connecting hole is provided in the middle of the connecting flange. Threaded holes are distributed around the connecting flange, and the threaded holes are evenly distributed on the connecting flange. A fastener is provided on the connecting flange to facilitate the connection between the connecting flange and the connecting piece, so that the connection between the flange and the connecting piece is tighter, and the electromagnetic signal will not leak out, thereby ensuring the use quality of the shielding cover. A shielding component is provided on the lower cover to improve the shielding performance of the shielding cover.

[0004] Although the existing technology can significantly reduce the leakage of electromagnetic signals, the middle of the lower cover is a horizontal structure, which can prevent the shielding cover from falling down easily during use and make the shielding cover more firmly fixed and not easily shaken, but the shielding effect inside the shielding cover is poor.
