[0002] As an important part of power grid equipment, the operating status of insulator strings is directly related to the safety and stability of the power grid. However, long-term exposure of insulator strings to harsh environmental conditions, such as high temperature, rain, snow, and humidity, can easily lead to a decrease in their insulation and mechanical properties, and thus form degraded insulators. Degraded insulator strings are very prone to flashover in humid or rainy and snowy weather. If not discovered and handled in time, they may cause serious string breakage and string drop accidents, posing a serious threat to the safe operation of the power grid. Therefore, regular inspections are required in daily maintenance.

[0003] Existing detection devices are often unable to be flexibly adjusted according to the actual length of the insulator string, resulting in the need to frequently replace detection devices of different specifications during the detection process. This is not only cumbersome to operate, but also increases the detection cost. Therefore, an insulator string detection device based on infrared hotspots is proposed to overcome the above problems.
