Problems solved by technology

[0003] At present, power grid companies mainly use manual inspections to detect cracks, and conduct visual inspections or other means of appearance inspection. However, there is no reliable way to check for internal cracks.
Therefore, the power grid company will replace insulators in large quantities every few years. In order to ensure safety, the replacement cycle is much lower than the service life of normal insulators, which will cause a lot of waste
[0004] For suspension insulators, they are mainly used to suspend overhead transmission lines, and the installation position is relatively high. Therefore, after the suspension insulators are put into use, it is difficult to detect the internal cracks through manual inspection at high altitude.

Description

technical field [0001] The present application relates to the technical field of product detection, and more specifically, to a detection device and method for a suspension insulator. Background technique [0002] Insulators provide electrical insulation and mechanical fixation and are therefore often used on transmission lines or substations. However, after long-term use of the insulator, cracks will occur inside it. When the crack reaches a certain level, it will cause the line to collapse and cause serious electrical accidents. Therefore, in order to prevent serious electrical accidents, it is necessary to detect internal cracks of insulators. [0003] At present, power grid companies mainly use manual inspections to detect cracks, and conduct visual inspections or other means of appearance inspection. However, there is no reliable way to check for internal cracks. Therefore, the power grid company will replace insulators in large quantities every few years. In order t...
