Description
technical field [0001] The invention relates to an insulator monitoring and detection system for a high-voltage transmission frame of a power grid. Background technique [0002] In the grid transmission system, the application of insulators is very common, so the performance of insulators plays an important role in the normal operation of the entire grid. [0003] On the high-voltage power transmission frame, the performance of the insulator is affected by the following conditions: 1. Dirt, such as bird droppings, dust; 2. Damage, due to long-term use outdoors, even in harsh weather conditions, the insulator will be damaged. cause some damage. [0004] In view of the above problems, the power grid staff generally judge the quality of the insulator by checking the appearance of the insulator and the discharge during observation, or disassemble the insulator for testing, but these methods are very inefficient and have certain safety hazards. Therefore, how to improve the det...
