Magnetic shielding structure of smoothing reactor

The invention discloses a magnetic shielding structure of a smoothing reactor. A ferromagnetic material is wound to form a cylindrical shielding body and is arranged in a non-magnetic conduction shellof the smoothing reactor, a round planar structure is arranged at a bottom surface of a lower end of the cylindrical shielding body and is made of a high-magnetic conduction material, a hole is formed in the center of the round planar structure, and a plurality of support holes are formed in the round planar structure with the central hole and are used for fixing the cylindrical shielding body ona support piece and isolating with a live-line part of the smoothing reactor. By the shielding structure disclosed by the invention, a space magnetic field around the smoothing can be effectively reduced, the influence on an environment of a converter station is reduced, and potential risk on health of a worker at the converter station and influence on surrounding equipment are prevented. 本发明公开了种平波电抗器的磁屏蔽结构，采用铁磁材料卷绕成筒状屏蔽体
