Description

technical field [0001] The invention belongs to the technical field of conductive coatings, in particular to an anti-corona acrylic conductive coating and its preparation method and application. Background technique [0002] Substations and transmission line wires often produce corona noise. The main reason for corona generation is that the wires are damaged during transportation and installation; or due to imperfect design considerations, the wire diameter is relatively small. Corona noise sources of conductors are widely distributed and located at a high position, and it is difficult to control them by setting up noise barriers and other measures. Therefore, it must be controlled from the source of the noise. The fundamental way to control corona is to reduce the local electric field intensity. The conventional method is to install a voltage equalizing device for treatment. For the case where the wire is long and there are many corona discharge points, this method will inc...
