Abstract

This paper elaborates the hazards to SF6 gas electrical equipment when the gas density decreases and its moisture exceeds the standard followed by a comprehensive analysis to the present situation of the online monitoring of SF6 gas density and moisture for high voltage apparatus. In order to prevent the potential harm

online monitoring device of internal moisture and density of the SF6 electrical equipment is proposed and developed. The monitoring device works basing on SF6 gas circulation. It realizes the online monitoring of internal moisture and density enabling a real-time understanding of SF6 gas chamber internal moisture level and density values. This system provides a valuable measure to taking all time control of the SF6 gas

which contributes to the prevention and elimination of hazardous incidents as well as to ensuring the safety running of electrical equipments.
