Description

technical field [0001] The invention relates to an automatic detection technology, in particular to a device and method for imaging and contamination detection of high-voltage line insulators. Background technique [0002] The insulators on the high-voltage lines are exposed all the year round. Due to the influence of the natural environment, dust, waste gas, etc. will form pollution on the surface of the insulators. When the environment is dry, the pollution will not affect the insulation degree of the insulator, but in a humid environment, the pollution will greatly reduce the insulation capacity of the insulator, causing leakage of high-voltage lines and endangering the safety of the power grid. In recent years, alarms have been set up to monitor the leakage current of each insulator. When the current exceeds the preset value, it will be uploaded to the supervision center immediately for processing. This scheme of setting the alarm to judge the location of the insulator ...
