Problems solved by technology

However, in the actual installation process, it is found that due to handling, transportation, vibration and other reasons, the two electrodes will be deformed, rotated, etc., and the distance between the two electrodes is different. It is difficult to adjust the distance between the two electrodes during installation. If the gap between the electrodes is too large or too small, the lightning protection effect will be reduced, and even the lightning protection effect will be lost.

Description

Technical field [0001] The invention relates to the technical field of lightning protection for power overhead lines, in particular to an insulator lightning protection device with adjustable discharge gap. Background technique [0002] An insulator is a special insulation control that can play an important role in overhead power transmission lines. The insulator usually includes a porcelain body, a core rod at one end of the porcelain body, and a steel cap at the other end of the porcelain body. When the external environment and electrical load conditions change, various electromechanical effects will degrade the insulators, causing insulation failure and critical line safe operation. Among many factors, lightning and lightning strikes cause the greatest damage to insulators. It is particularly urgent to study the protection measures of insulators under lightning conditions. The existing method is to provide electrodes at both ends of the insulator, and there is a gap between ...
