Description

technical field [0001] The invention belongs to the technical field of high-voltage protective appliances, relates to the direction of insulator pollution monitoring, and in particular relates to an online monitoring system for high-voltage insulators. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. [0003] Floating dust and other pollution...

AI Technical Summary

Problems solved by technology

Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not have a significant effect and will damage the service and operating life of the entire line

[0003] Floating dust and other pollution adhere to the surface of the insulator, forming a path and being broken down by the voltage at both ends of the insulator. Especially in wet weather, dirty insulators are prone to flashover discharge, and the pollution caused by pollution is more harmful than that caused by lightning strikes. Larger, more serious losses
