Abstract

The optical structure suitable for the on-line detection of high-voltage equipment is designed, the on-line analysis of trace decomposition gas composition of insulating gas SF6 of the high-voltage equipment is realized, and the prototype is developed. The optical noise suppression technology suitable for the field is studied, the optical path system is designed to withstand the gas pressure of high-pressure equipment, and the influence of field vibration and temperature change of the high-pressure equipment on the optical path structure is solved. The judgment threshold of expert diagnosis system is formed to predict the operation state and fault type of GIS equipment according to the changes of types and contents of typical decomposition products of the sulfur hexafluoride. The above achievements lay the theoretical foundation for realizing the on-line monitoring of the insulation status of SF6 Electrical equipment, greatly promoted the development and application of ultraviolet spectrum and non dispersive infrared optical live sensing detection technology, provided effective guarantee for the safe and stable operation of the sulfur hexafluoride electrical equipment, further improved the reliability of equipment, and ensured the ability of power grid to safely and continuously provide clean energy, ensure reliable power supply and good social benefits.
