The invention discloses an anti-corona device applied to a transmission line clamp. The anti-corona device comprises a metal mask and an elastic clip arranged on the metal mask, wherein the metal maskcomprises a top surface and four side surfaces and various edges are in smooth rounded transition; a through hole through which a bolt on the transmission line clamp passes is formed in the top surface; the elastic clip is provided with a U-shaped elastic clamping part for clamping the bolt; a trigger part for opening the U-shaped elastic clamping part is arranged on the top surface; and the trigger part can move in the direction vertical to the top surface to release the U-shaped elastic clamping part. The anti-corona device disclosed by the invention aims at solving the technical problem ofcorona discharge caused by a structure with a too small curvature radius on the line clamp of a high-voltage transmission line in the prior art.
Description
technical field [0001] The invention relates to the field of power transmission line fittings, in particular to an anti-corona device applied to transmission line clips. Background technique [0002] The design and application conditions of live metal fittings on transmission lines are related to their surface working field strength. When the surface working field strength is higher than the corona initiation field strength, corona discharge will be generated on the surface of the metal fittings. The size of the working field strength of the fittings is closely related to the structure of the fittings. Studies have shown that the smaller the curvature radius of the fittings surface, the higher the working field strength on the surface under the same voltage, the more likely corona discharge will occur at this place, resulting in electric shock. Halo noise and power loss are not conducive to energy saving and environmental protection. [0003] There are many places where the...
