Abstract
The utility model provides a SF6 decomposition product detection device based on an electrochemistry hydrogen sensor. The SF6 decomposition product detection device based on the electrochemistry hydrogen sensor comprises a carbon monoxide sensor, a sulfur dioxide sensor, a hydrogen sulfide sensor, an electrochemistry hydrogen sensor, an active directory (AD) gathering module, an algorithmic remote manipulation (ARM) handler and a display controller. The carbon monoxide sensor, the sulfur dioxide sensor, the hydrogen sulfide sensor and the electrochemistry hydrogen sensor are connected with the AD gathering module. The AD gathering module is connected with the ARM handler. The ARM handler is connected with the display controller. The SF6 decomposition product detection device based on the electrochemistry hydrogen sensor can be effective to make up for defects of a carbon monoxide (CO) detection in an existing SF6 decomposition product. Interferences of hydrogen (H <2>) for the carbon monoxide sensor can be removed to be real and accurate to detect the CO contents in the SF6 electrical equipment. Meanwhile, an index of the H <2> contents of a sample gas can be enhanced so as to provide more detailed and reliable data. Therefore, the SF6 decomposition product detection device based on the electrochemistry hydrogen sensor is convenient to accurately judge whether breakdowns and hidden dangers exist in the electrical equipment or not.
