Type: conference-paper
Abstract: Air switchgear plays a critical role in control and protection during power transmission and distribution, where internal insulation defects may cause partial discharge (PD), threatening equipment safety. This paper aims to study the detection method of gas decomposition characteristics during partial discharge within air switchgear and designs an NO2 gas sensor based on a p-GO-n-WO3 heterojunction for detecting partial discharge characteristic gases. The preparation process of the p-GO-n-WO3 heterojunction gas sensor is detailed, followed by experimental verification of the sensitivity and response characteristics of the sensor to NO2 gas at room temperature. The results demonstrate that the 10 wt% GO-WO3 sensor exhibits high sensitivity at room temperature, effectively detecting NO2 gas generated by partial discharge in air switchgear, thereby providing technical support for improving equipment operational reliability.
