Research on Pollution Flashover Detection of Power Insulator Based on High Frequency Electromagnetic Wave

Abstract

In power system accidents, power insulators account for a large proportion of pollution flashover accidents caused by pollution. Real-time detection of pollution flashovers is an important guarantee for reducing power system accidents. This paper proposes a principle of using partial discharge of polluted insulators to generate electromagnetic waves to achieve pollution flashover detection. According to the characteristics of electromagnetic waves, this method selects the corresponding frequency band antenna to receive and amplify electromagnetic wave signals, filter out signal interference, and perform data analysis and processing to detect pollution flashover. Experiments show that this method has high detection accuracy and strong anti-interference ability. It can judge the severity of pollution and the type of pollution in real time. It has strong practicability and is widely used.
