And the use of CT (induction power taking) changes the distribution of an electric field, causes internal insulation heating, changes the thermal stability and seriously threatens the normal operation of a power system, so the CT power taking mode is an unreliable mode.
And when the local field intensity reaches a certain value, the gas is locally ionized, and blue fluorescence appears at the ionized part, namely the corona phenomenon.
The corona is generated because the uneven conductor generates a very uneven electric field, and when the voltage around the electrode with a small curvature radius around the uneven electric field rises to a certain value, the air is dissociated to generate discharge, so that the corona is formed. Because the electric field is very weak at the periphery of the corona and no collision ionization occurs, the charged particles at the periphery of the corona are basically ions, and the ions form a corona discharge current. In brief, a conductor electrode with a small radius of curvature discharges air, creating a corona.
During corona discharge, air flow can be generated due to ion movement, and the air flow can be utilized to invent a power generation device which is used as a low-voltage power supply for equipment such as monitoring, monitoring and warning on a high-voltage power transmission line.
