Description

technical field

The invention relates to the technical field of power line fault detection devices, in particular to an insulator with a fault indication function.

Background technique

With the rapid development of the national economy and the continuous improvement of the voltage level of the transmission lines of the power system, it is very important to ensure the normal operation of the cable lines. Insulators play a vital role in ensuring line safety. Due to the harsh working environment of insulators, insulators are often affected by the surrounding environment and weather, so that insulators often have flashovers, cracks in the connection between insulating materials and metal terminals, and brittle fractures, which reduce or even lose the insulation function. . Therefore, regular inspections of insulators are required to keep the line running stably. At present, the common insulator fault detection methods include UAV infrared thermal imager detection, optical imaging picture detection and direct manual observation methods. However, there are errors in these methods, and the workload of each inspection is relatively large, and it is necessary to inspect the insulators at each location, and real-time inspection cannot be achieved. For this detection method, it is possible that small cracks cannot be detected in the obtained pictures, which may lead to brittle fracture of the insulator during operation. It is also possible that the insulator has flashover but can still work normally until the next flashover occurs again. , which will affect the line and residential electricity consumption.

To sum up, if the insulators can be inspected in time, and the insulators that have flashover, leakage or cracks have been replaced in time, it will avoid secondary damage to the insulators, resulting in damage to power equipment that affects industry and industry. Residential electricity.

Therefore, it is necessary to provide a new insulator with a fault indication function to solve the above technical problems.
